[0001] Related Applications This application is a continuation of U.S. Provisional Patent Application No. 62 / 584,899, filed November 12, 2017. No. 60 / 699,999, filed on May 1, 2003, the contents of which are incorporated herein by reference in their entirety.
[0002] The present disclosure generally relates to methods for detecting or quantifying non-coding nucleic acid sequences in a sample. Detection of non-coding RNA molecules or target diagnostics, particularly molecular biology of cancer, including breast cancer Marker identification and use. [Background technology]
[0003] Widespread reprogramming of gene expression is a hallmark of cancer development. Systematic identification of regulatory pathways that drive pathological gene expression patterns is crucial for understanding and improving cancer. Over the years, numerous regulatory mechanisms have been identified that regulate the function of cancer cells. It has been implicated in the oncogenic expression of genes involved in differentiation, survival, invasion, and metastasis. Although much research has focused on the transcriptional pathways underlying carcinogenesis, post-transcriptional regulatory pathways are also important. have emerged as key regulators of processes such as gene silencing. MicroRNAs (small non-coding RNAs), a subclass of small RNAs, function in A) was one of the first characterized post-transcriptional regulators of breast cancer progression (1). RBP-binding proteins (RBPs) are also important post-transcriptional regulators of gene expression, with several specific Several RBPs have been shown to affect carcinogenesis and cancer progression (e.g., 2-5). Recently, other classes of small non-coding RNAs, tRNAs (6) and tRNA fragments (7 ) has been demonstrated to play a fundamental role in breast cancer progression.
[0004] Although a diverse repertoire of regulatory mechanisms is involved in cancer, there are commonalities among them. Their distinctive feature is that they exploit or dysregulate existing pathways within the cell. In other words, cancer cells overactivate oncogenic pathways and cause tumors. To downregulate tumor suppressor pathways, somatic mutations (e.g., KRAS, 8), gene fusions, In cases of BCR-ABL, epigenetic modifications (e.g., promoter hypermetastasis) 10), and disruption of regulatory mechanisms (NFkB transcription factors, 10). (11, 12). These strategies may be used to investigate the pathology of pre-existing regulatory programs. While dependent on the node, cancer cells may develop specialized regulatory pathways that drive tumorigenesis. There is the often overlooked possibility that a new system can be created.

[Brief explanation of the drawings]
[0009] [Figure 1A]We demonstrate the discovery, annotation, and validation of cancer-specific orphan noncoding RNAs in breast cancer. Figure 1A is a heat map depicting the relative abundance of 437 small noncoding RNAs significantly expressed in breast cancer lines but not in normal HUMEC. HUMEC were treated in triplicate, while all other cell lines were analyzed in duplicate. Figure 1B is a heat map showing that of the 437 small RNAs identified in (Figure 1A), 201 were significantly expressed in small RNA gene expression profiles of breast tumor biopsies collected as part of the Cancer Genome Atlas (TCGA-BRCA), and these 201 were largely absent in adjacent normal tissues collected from approximately 200 individuals in this dataset. Figure 1C is a heat map showing that these 201 cancer-specific small RNAs were classified as orphan noncoding RNAs or oncRNAs and independently validated in a third dataset comparing small RNA profiles from four normal epithelial samples and 10 patient-derived xenograft models. [Figure 1B] Same as above. [Figure 1C] Same as above. [Figure 2A]Orphan small RNAs are relatively abundant in cancer cells and rarely detected in normal tissues. In Figure 2A, to identify cancer-specific small RNAs, RNAs that are rarely present in normal cells / tissues but commonly expressed in cancer cells were searched for. Such RNA species were identified from two independent sources: (i) profiles of breast cancer cell lines compared with HUMEC, and (ii) The Cancer Genome Atlas dataset (TCGA-BRCA), which contains approximately 200 normal tissue biopsies and approximately 1,000 tumor samples. These two independent sets were then superimposed to identify orphan noncoding RNAs (oncRNAs). As shown in Figure 2A, strong overlap was observed between these two analyses (hypergeometric test, P value approximately 0). In Figure 2B, the total abundance of 201 oncRNAs was calculated for four normal epithelial samples and 10 PDX models. As shown in Figure 2B, total oncRNA expression can perfectly predict whether a sample is cancerous or normal (both AUC and AUPRC equal 1.0). [Figure 2B] Same as above. [Figure 3A]We demonstrate that oncRNA T3p is strongly associated with breast cancer progression. Figure 3A is a volcano plot comparing oncRNA expression in low-metastatic breast cancer cells versus their highly metastatic derivatives. Significantly upregulated oncRNA T3p in highly metastatic cells is highlighted. Figure 3B is a schematic diagram showing that T3p maps to the 3' end (CR7 domain) of TERC, the RNA component of telomerase. Figure 3C shows the expression of T3p (cpm) in breast tumor biopsies and their corresponding normal tissues from the TCGA-BRCA dataset. Association p values were calculated using a paired Wilcoxon test. Figure 3D shows T3p expression across the entire TCGA-BRCA dataset. Figure 3E shows a survival analysis of the TCGA-BRCA dataset for patients stratified based on T3p expression in their tumors. Samples from the top and bottom thirds were included in this analysis (log-rank test). Figure 3F shows the expression of T3p among normal samples, stage I, and stage II or III samples in the TCGA-BRCA dataset (*: P<0.05; ***, P:<0.001; using the Mann-Whitney test). [Figure 3B] Same as above. [Figure 3C] Same as above. [Figure 3D] Same as above. [Figure 3E] Same as above. [Figure 3F] Same as above. [Figure 4A]We demonstrate that oncRNA T3p is associated with aggressive breast cancer. Figure 4A shows a summary of the number of samples in the TCGA-BRCA dataset based on sample type (normal vs. breast cancer). Each contingency table also includes an accompanying Fisher's exact chi-square test. Figure 4B shows stratification of patients in the TCGA-BRCA dataset based on whether T3p was detected in their tumor biopsies. Even minimal detection of T3p in biopsies is associated with poor survival in breast cancer (p calculated based on the log-rank test). Figure 4C shows a comparison of T3p expression levels in TCGA-BRCA samples divided based on ER, PR, or HER2 status. Figure 4D shows that T3p is significantly expressed in breast cancer PDX models (***: P<0.001; Mann-Whitney test). [Figure 4B] Same as above. [Figure 4C] Same as above. [Figure 4D] Same as above. [Figure 5] We show that T3p promotes metastatic progression. The gene expression changes induced by anti-T3p LNAs are nearly equivalent regardless of whether (i) scrambled LNA or (ii) anti-TERC (but not T3p) LNA controls are used. Pearson correlation coefficients and associated P values are included. [Figure 6A]T3p is shown as a regulator of gene expression and a driver of metastatic progression. Figure 6A shows a comparison of gene expression changes induced by anti-T3p LNA in MDA-LM2 cells to T3p mimics in MDA-MB-231 cells. The accompanying Pearson correlation (P value approximately 0) is reported. Figure 6B shows bioluminescence imaging plots of lung metastases from MDA-LM2 cells transfected with anti-T3p LNA (LNA-T3p) or scrambled LNA (LNA-Scr) (n = 4 or 5 in each cohort). Statistical significance was determined using two-way ANOVA. The area under the curve for each mouse was also calculated (change in normalized lung photon flux multiplied by the number of days elapsed). Error bars indicate the standard error of the mean. **: P < 0.01 by one-sided Mann-Whitney test. Figure 6C visually illustrates the number of visible metastatic nodules counted in three mice from each cohort. The right panel shows representative lung sections stained with hematoxylin and eosin (H&E) from each cohort, along with median counts. Error bars indicate the standard error of the mean. *: P<0.05 by one-sided Mann-Whitney test. [Figure 6B] Same as above. [Figure 6C] Same as above. [Figure 7A] Systematic profiling of oncRNAs in the exosomal compartment is shown. Figure 7A shows that the majority of oncRNAs were detected in exosomal small RNA data collected from MDA-MB-231 cells but not in normal HUVEC cells. Figure 7B shows small RNA profiling of exosomal RNA collected from breast cancer cell lines and normal HUVECs. A heat map showing oncRNA detection among extracellular populations is shown. Figure 7C shows oncRNA detection in serum samples collected from breast cancer patients with stage II and III disease. As a baseline for evaluation, data from 11 healthy individuals from an independent study were used as a reference. [Figure 7B] Same as above. [Figure 7C] Same as above. [Figure 8A]We demonstrate that T3p can be detected in exosomes and circulating compartments. Figure 8A shows the results of previously published small RNA-seq data (7) and quantitative RT-PCR validation of T3p upregulation in highly metastatic MDA-LM2 cells compared to their low-metastatic parental cells (n = 6 for each sample, **: P < 0.01; two-tailed Mann-Whitney test). Figure 8B demonstrates that T3p can be detected at high levels in the vast majority of serum samples collected from patients, while it is present at very low levels (or undetectable) in serum samples collected from healthy individuals. [Figure 8B] Same as above. [Figure 9A] We demonstrate that oncRNA T3p is associated with aggressive breast cancer. Figure 9A shows normalized T3p expression by small RNA sequencing for the indicated cell lines on the x-axis. All cancer lines were prepared and processed in biological triplicates, and HMECs in biological duplicates. Cell lines are grouped by subtype: HMEC (circles on the left side of the panel), triple-negative breast cancer (TNBC; squares, triangles, and diamonds in the center of the panel), HER2-positive (circles and squares on the right side of the panel), and luminal (triangles on the right side of the panel). Figure 9B shows a comparison of T3p expression levels in TCGA-BRCA samples divided based on ER, PR, or HER2 status (n = 1033, 1030, and 715, respectively). Mean values ± standard deviations are shown for each cohort. Figure 9C shows relative T3p expression measured by qRT-PCR in two low-metastatic and two highly metastatic breast cancer PDX models. [Figure 9B] Same as above. [Figure 9C] Same as above. [Figure 10A]We demonstrate that T3p can be detected in both the extracellular and circulating compartments. Figure 10A shows that T3p was present in sequenced small RNAs isolated from extracellular vesicles (EVs) from 7 / 8 breast cancer cell lines but not in HMEC EVs.

RNA initiates translation by binding to target mRNA at sites with appropriate sequence complementarity. acts as a lesser (Ameres et al., 2007), but is highly abundant in the cytoplasm Y RNA regulates RNA quality by influencing the subcellular location of Ro proteins. It functions in the regulation of mRNA translation (Sim et al., 2009). The repression activity of molecular non-coding RNAs silences retrotransposons at defined subcellular locations. In addition to signaling piRNAs, other classes of siRNAs, including endogenous siRNAs, It is shared with ncRNA (Chuma and Pillai, 2009). The activity of the code RNA is abundant at sufficient levels in the cytoplasm and localized to endosomal membranes. Depends on interaction with the RNA-induced silencing complex (RISC) (Gibbing s et al., 2009, Lee et al., 2009a), but a small amount of low-molecular-weight Non-coding RNAs have a smaller effect on translational repression. Even subtle changes in the levels of small non-coding RNAs can already affect cellular processes. However, strong perturbations can cause disease. Interaction with non-coding RNA partners and correct subcellular localization are essential for small non-coding RNAs These are interrelated factors that control the physiological functions of the .,2012, Wee et al.,2012).
[0046] Small RNAs can be secreted into cell-derived extracellular vesicles such as exosomes. Both A and small non-coding RNA species have been found to be contained in exosomes. Therefore, exosomes are a key component in the transport of RNA content and protecting it from degradation in the environment. This may provide a means for protection and provide a stable and reliable detection of RNA biomarkers. Make the selected source available.

(1990) J Clin Microbiol See Vol. 28, 495-503, which is incorporated herein by reference in its entirety. The following is stated:
[0060] Determining the levels of small RNA biomarkers in a sample The levels of one or more small non-coding RNA biomarkers in a biological sample can be determined by any suitable method. The level or amount of small non-coding RNA in a sample can be determined by various methods. Any reliable method for detecting small non-coding RNAs can be used. Generally, small non-coding RNAs are detected using methods such as For example, amplification-based methods (e.g., polymerase chain reaction (PCR), real-time polymerase chain reaction (RTC)) polymerase chain reaction (RT-PCR), quantitative polymerase chain reaction (qPCR), low-cost hybridization-based methods (e.g., hybridization Arrays (e.g., microarrays), NanoString analysis, Northern blot analysis, Lot analysis, branched DNA (bDNA) signal amplification, in situ hybridization tion), and sequencing-based methods (e.g., Illumina or IonT publicly available data for mRNA, including next-generation sequencing using current platforms Detection or detection of RNA from samples (including fractions thereof) such as RNA samples isolated by various known methods. Other exemplary techniques include ribonuclease protection assays (RPAs). A) and mass spectrometry.
[0061] In some embodiments, the RNA is converted to DNA (cDNA) before analysis. A can be produced by reverse transcription of isolated small non-coding RNA using conventional techniques. In some embodiments, the small non-coding RNA is amplified prior to measurement. In this example, the levels of small non-coding RNAs are measured during the amplification process. In embodiments, the level of small non-coding RNA is not amplified prior to measurement. Some exemplary methods suitable for determining levels of non-coding RNA are described in more detail below. These methods are provided by way of example only; other suitable methods may be used as well. It will be apparent to those skilled in the art that other methods may be used.
[0062] A. Amplification-Based Methods including but not limited to PCR, RT-PCR, qPCR, and rolling circle amplification Multiple amplification-based methods for detecting levels of unspecified small non-coding RNA nucleic acid sequences Other amplification-based techniques include, for example, ligase chain reaction, multi-site PCR, and Amplification using suitable ligatable probes (multiplex ligabl e probe amplification), in vitro transcription (IVT), strand displacement amplification amplification, transcription-mediated amplification, RNA (Eberwine) amplification, and other methods known to those skilled in the art. Examples include the law.
[0063] A typical PCR reaction involves multiple steps that selectively amplify a target nucleic acid species: Cycles include: a denaturation step in which the target nucleic acid is denatured; a set of PCR primers ( i.e., forward and reverse primers) anneal with complementary DNA strands. The annealing step involves the primer extension step, which is performed by a thermostable DNA polymerase. By repeating these steps multiple times, DNA fragments can be generated. The fragment is amplified to produce an amplicon corresponding to the target sequence. A typical PCR reaction consists of , which involves 20 or more cycles of denaturation, annealing, and extension. The ring and extension steps can be performed simultaneously, in which case the cycle consists of two steps. The reverse transcription reaction (the generation of cDNA sequences complementary to small non-coding RNAs) is the only step involved. A reverse transcription reaction (which produces a sequence) can be performed prior to PCR amplification. This involves the use of a DNA polymerase (reverse transcriptase) and primers.
[0064] Kits for quantitative real-time PCR of small non-coding RNAs are known and commercially available. Examples of suitable kits include the TaqMan miRNA Assay (Appli ed Biosystems) and mirVana.qRT-PCR miRNA detection Kits include, but are not limited to, the kit (Ambion). The molecular non-coding RNA is identified by a universal primer sequence, polyadenylation sequence, or adaptor. The primer is ligated to a single-stranded oligonucleotide containing a target sequence, Primers complementary to the mer sequence, poly(T) primers, or primers complementary to the adapter sequence The DNA can be amplified using primers containing the desired sequence.
[0065] In some cases, custom qRT-PCR is used to determine small non-coding RNA levels. Assays can be developed to measure small non-coding RNAs in biological samples (e.g., body fluids). For example, methods involving extended reverse transcription primers and locked nucleic acid modified PCR are used to Using the method, custom qRT-PCR assays can be developed. The code RNA assay uses a dilution system of chemically synthesized small non-coding RNA corresponding to a target sequence. This can be done by running an assay on the array. Furthermore, when used as a calibration curve, these These data allow for estimation of the absolute abundance of small non-coding RNAs measured in biological samples. To perform Noh.
[0066] Optionally, check the amplification curves to ensure that Ct values are evaluated within the linear range of each amplification plot. Typically, the linear range spans several orders of magnitude. For small non-coding RNAs, obtain a chemically synthesized version of the small non-coding RNA. A dilution series can then be analyzed to determine the sensitivity limit and linear range of quantitation of the assay. Relative expression levels can be calculated using the method described, for example, in Livak et al., Methods (2001). ) December;25(4):402-8 do.
[0067] In some embodiments, two or more small non-coding RNAs are amplified in a single reaction volume. For example, multiplex q-PCR, such as qRT-PCR, uses two or more pairs of primers and / or By using two or more probes, you can mix at least two nucleotides of interest in one reaction volume. The primer pairs allow for simultaneous amplification and quantification of small non-coding RNAs of interest. The molecule comprises at least one amplification primer that specifically binds to non-coding RNA, The R&D units are labeled so that they can be distinguished from one another, allowing multiple small non-coding R&D units to be Simultaneous quantification of NA becomes possible.
[0068] Rolling circle amplification is the process of converting circularized oligonucleotide probes into linear or cyclic oligonucleotides under isothermal conditions. is a DNA polymerase-driven reaction that can replicate either by cleavage or geometric kinetics. (e.g., Lizardi et al., Nat. Gen. (1998) 19(3) :225-232;Gusev et al., Am. J. Pathol. (2001) 159(1):63-69, Nallur et al., Nucleic Acids Res. (2001) 29(23):E118). The presence of two primers In the presence of β-glucan, one hybridizes to the (+) strand of DNA and the other to the (-) strand. The complex pattern of strand displacement was observed in 10 of each DNA molecule within 90 minutes. 9Creating more than 100 copies By using a single primer, tandem sequences of closed circular DNA molecules can be linked. A bound copy can be formed. This process can be carried out using matrix-bound DNA. The template used for rolling circle amplification can also be reverse transcribed. This method can be used to identify small non-coding RNA sequences and very low small non-coding RNA sequences. A concentration can be used as a sensitive indicator of expression levels (e.g., Cheng et al.,Angew Chem.Int.Ed.Engl.(2009)48( 18):3268-72, Neubacher et al., Chembiochem (2009)10(8):1289-91).

Non-positive spots after background removal and outliers detected by the ESD procedure were removed. The resulting signal intensity values are normalized to the median value per chip and then used to obtain the geometric mean and standard error for each small non-coding RNA. Each signal can be transformed into a logarithm base 2 and a one-sample t-test can be performed. To increase the robustness of the data, each small non-coding RNA was spotted multiple times. Independent hybridizations for the samples can be performed on the chip.
[0072] Microarrays for profiling the expression of individual small non-coding RNAs in disease For example, RNA can be extracted from the sample and, if desired, Small non-coding RNAs are size-selected from total RNA. Oligonucleotide linkers are added. The resulting ligation product can be attached to the 5' and 3' ends of small non-coding RNAs. The reaction product is used as a template for the RT-PCR reaction. The primers are designed to bind fluorophores to their 5' ends, allowing the detection of PCR products. The PCR products are denatured and then hybridized to a microarray. The corresponding small non-coding RNAs, called target nucleic acids, are captured on the array. PCR products complementary to the probe sequence base-pair at the spots where the capture probes are immobilized. The spots are then scanned using a microarray laser scanner. When excited using a
[0073] Several positive and negative controls and array data normalization methods were then used to analyze each sequence. The fluorescence intensity of the pot is evaluated in terms of the copy number of a specific small non-coding RNA. The result is an assessment of the expression levels of specific small non-coding RNAs.

For example, T4 RNA ligase and and 3'-end labeling of RNA using fluorophore-labeled short RNA linkers. The fluorescent probes are complementary to the corresponding small non-coding RNA capture probe sequences on the array. The proteophore-labeled small non-coding RNAs base-pair at the spots where the capture probes are immobilized. Then, several positive and negative controls and arrays are hybridized. Using data normalization methods, the fluorescence intensity of each spot was determined to be the proportion of copies of a specific small non-coding RNA.

On-line chromatography of endonuclease digests by reversed-phase HPLC. The mass shift from the expected mass based on the RNA sequence determined the transcript. The presence of post-modifications can then be revealed by tandemly sorting the ions with unusual mass / charge values. and isolate them for MS sequencing to determine the sequence arrangement of post-transcriptionally modified nucleosides. This can be done.
[0083] Matrix-assisted laser desorption / ionization mass spectrometry (MALDI-MS) has also been used to characterize post-transcriptional modifications. It is used as an analytical method to obtain information about nucleosides. MAL-based techniques can be distinguished from ESI-based techniques by a separation step.

The cells were obtained from the American College of Cancer Culture Collection (ATCC) and transfected according to their protocol. and grew it.
[0134] All cells were cultured in a humidified incubator at 37°C and 5% CO2. B-231, MDA-LM2, CN34-par, CN34-Lm1a, MCF7, and and MDA-MB-453 cell lines were cultured in 4.5 g / L glucose, 10% FBS, 4 mM of L-glutamine, 1 mM sodium pyruvate, penicillin (100 units / mL), Supplemented with streptomycin (100 μg / mL) and amphotericin (1 μg / mL). HCC1395, ZR-75-1, and HCC1395 were grown in DMEM-based medium supplemented with HCl. CC38 cell line was cultured in 10% FBS, 2 mM L-glutamine, penicillin (100 units / mL), streptomycin (100 μg / mL), and amphotericin (1 μg / SK-BR-3 cell line was grown in RPMI 1640-based medium supplemented with 1000 mg of 10 ... 10% FBS, penicillin (100 units / mL), streptomycin (100 μL), in McCoy's 5a modified medium supplemented with 1 μg / mL), and amphotericin (1 μg / mL). HMECs were obtained from Thermo Fisher Scientific. and grown in pre-made HuMEC medium (Thermo Fisher Scientific). I bred them.
[0135] Small RNA and exosomal RNA extraction and sequencing of RNA from extracellular vesicles Preparation of conditioned medium and complete conditioned medium for isolation was performed using 7 x 10 5 Seeding cells with After 24 hours, the cells were washed twice with PBS and 10 mL of exosomes was added. After 48 hours, the medium was centrifuged at 200 × g for 15 minutes, and the supernatant was FBS was collected by removing the exosomes from the culture medium. Remove exosomes by substituting with HCl (Fisher Scientific) The exosome-depleted HMEC medium was incubated at 4°C for 100,000 cycles. The medium components of bovine pituitary extract were prepared by centrifugation at × g for 16 hours.
[0136] Extracellular vesicle RNA was collected using Cell Culture Media Exosome Pu rification and RNA Isolation kit(Norgen Using a PBS (BioTek), a single PBS was prepared from 5 mL of conditioned medium prepared as outlined above. RNA from the conditioned medium was purified using miRNeasy serum / plasma kit. The total intracellular ATP was isolated from 400 ul of complete conditioned medium using a Qiagen ELISA kit. RNA samples were purified using Norgen Biotek's small molecule RNAi kit according to the manufacturer's protocol. RNA samples were extracted using an RNA purification kit. The RNA samples were then purified according to the manufacturer's protocol ( Bio Scientific) to use NEXTflex Small RNA Prepared for high-throughput sequencing using Sequencing Kit v3 The resulting library was then sequenced and processed as recommended by the manufacturer. In summary, we used cutadapt(v1.4) to remove the adapter sequences and The first and last degenerate sequences of each read were trimmed. Using ie2 (v2.3.3), the obtained sequences were cloned into the human genome (build hg38 The resulting BAM files were then sorted and used for further analysis. Extracellular vesicle RNA was converted to BED for ELISA. a / serum Exosome Purification and RNA iso was isolated from serum samples using a lation kit (Norgen Biotek). .
[0137] Small RNA sequencing data from TCGA-BRCA and TCGA-BRCA projects The identification of oncRNA reads by the project was performed using the Genomic Data Common Download the sample in BAM format (hg38) from GDC A. Annotation was performed using PI. The Piranha package was used for BED format conversion. J 40 The loci of expressed small RNAs were identified using , merged across all samples using mergeBed to identify the genes occurring in breast tissue and breast cancer. We generated a comprehensive list of expressed small RNA loci.
[0138] By enumerating small RNA sequences obtained from breast cancer cell lines and HMECs, We generated a count table for each small RNA locus. They normalized the resulting table by library size and calculated the total number of replicates across all three HMEC replicates. Only loci for which no reads were observed in the whole genome were retained. Using robust statistical tests, we compared the data across all cancer cell lines or for each subtype individually (TNBC, HER2+, and luminal) were compared: (i) we used the DESeq R package (ii) we used Fisher's exact test to calculate adjusted p-values. The present inventors compared the presence and absence of each small RNA in the former test. had an adjusted P value <0.05 in the latter test or P across all comparisons in the latter test Loci with <0.1 were selected.
[0139] 437 loci (listed in Figure 1A) met these criteria. Next, we normalized each column to its maximum value and performed k-means clustering (k=3). For the TCGA-BRCA database, we have identified subtypes annotated Among all samples tested (based on PAM50 classification) and all small RNA loci Generate a similar count table and normalize the resulting table to counts per million reads. We generated a table of the number of small RNAs (cpm) in normal cells. To identify small RNAs that are rarely present in normal samples, we first Only loci with 90th percentile expression below 0.5 cpm in the sample were retained. Of the 437 loci listed above, 268 passed this step. We performed Fisher's exact test to confirm all the differences between tumor samples and normal biopsies. The present inventors compared the presence of small RNAs in normal samples and each of the breast cancer subtypes. We then performed a similar comparison between the two groups, with an adjusted p-value of <0.05. Loci that were significant in at least one of these tests were retained. Small RNAs pass through this final step and are therefore classified as orphan non-coding RNAs. The present inventors have not previously classified any of these small RNAs as miRNAs, s We confirmed that they were not annotated as noRNA or tRNA.

We performed a survival analysis based on the expression of T3p in the tissues. Stratify patients based on β and generate Kaplan-Meier curves using all tertiles. Log-rank (Mantel-Cox) tests were performed to calculate the associated P values. Clinical data were also used to compare T3p expression between early and late stage tumors (unilateral Mann-Whitney U test). T3p regulation and gene expression profiling We performed miR- CURY LNA inhibitor (Exiqon) was used: T3p:CAGGACTCGGC TCACACATGC;TERC:TTGTCTAACCCTAACTGAGAAGG; Scrambled sequence: AGACGACAGCTGGATCACACG.

We then administered LNA to highly metastatic MDA-LM2 cells. The mimics and mimetics were transfected into MDA-MB-231 parental cells and subjected to gene expression profiles as previously described. Profiling was performed 7 Differential gene expression analysis was also performed as previously described. 7 . Tough Decoy and in vivo lung colonization and tumor growth assays stomach MDA-LM2 cells were incubated with anti-T3p or scrambled LNA (same as above). After transfection, the cells were transfected into the tail vein of immunodeficient NOD SCIDγ (NSG) mice for 48 hours. The mice were injected into the vasculature via the endothelial cells (2.5 x 10 per mouse). 4 (n=5 per cohort) In vivo imaging and curve comparison were performed as previously described. 19 Next , Lungs were removed and fixed from at least three mice per cohort (middle signal). Sectioned, stained (H&E), and quantified as previously described 19 . To induce stable inhibition of T3p, we used a lentiviral backbone The T gene for this small RNA was expressed under the RNA Pol III promoter (pLKO.1). We then stably transduced MDA-LM2 cells and expressed pulmonary Colony formation assays were performed (as above; 5 × 10 per mouse). 4 cells) HCC1395 cells were similarly transduced, with 2 x 10 cells per mouse. 5 cells were injected Orthotopic tumor growth assays were performed in 50 ul of PBS mixed with 50 ul of Matrigel.

The tumor diameter (L) and width (W) are measured every 2 days and calculated using the formula πLW2 / 6. Once the tumor reached 800 mm, the tumor volume was determined. 3 When the volume reaches In vitro cell proliferation: Cancer cell proliferation assay was performed at 0 5 x 10 on the day 4 cells were seeded and then plated in triplicate on days 3 and 5.

RNA-binding proteins with known binding sites were added. 42 Next, the present inventors investigated the TCGA- Co-expression between T3p levels in the BRCA dataset and levels of genes on this list The present inventors performed an analysis of the upregulated and regulated IL-111 in highly metastatic MDA-LM2 cells. and similarly in breast cancer samples compared to normal biopsies in the TCGA-BRCA dataset. Based on these criteria, genes with high and strong associations were overlaid. We identified seven candidates, two of which have known double-stranded binding activity. The CR7 domain of TERC is assembled (i.e., forms a double-stranded region), The inventors have demonstrated that these proteins (i.e., DROSHA and TARBP2) We concluded that DR1 is the best candidate for investigation. OSHA and TARBP2, and further interact with these proteins, respectively DGCR8 and DICER1, which are known to be involved in the development of gliomas, were knocked down (IDT).

[0144] First, we investigated the accessibility of potential regulators in cancer cells, which are present only in cancer cells. It was determined whether there existed a set of small RNAs that could provide a viable pool. OncRNA is detectable only in cancer cell lines, but not in normal cells. To test this hypothesis, small RNA sequencing was performed on nine species of breast cancer cell lines (all representing major breast cancer subtypes) and human mammary epithelial cells as a reference The results were performed on human mesenchymal stem cells (HMEC). The results were significant in all breast cancer lines, but not in HMEC samples. 437 unannotated small RNAs were identified that were not detected by the IL-1 gene (Figure 1A).
[0145] To further narrow the search and strengthen these findings, a similar analysis was performed on approximately 200 We provided small RNA expression profiles of normal tissue samples and all 1200 breast cancer biopsies. Small molecules obtained from The Cancer Genome Atlas (TCGA) This analysis was performed on RNA sequencing data. 268 cancer-specific low-molecular-weight genes were identified. Two RNA molecules were identified, 201 of which were also present in the breast cancer cell lines. The highly significant overlap between the independent analyses of 201 on with high confidence is shown in Table 1 below. A set of cRNAs was identified (Fig. 1B and Fig. 2A). [Table 1-1] [Table 1-2] [Table 1-3] [Table 1-4] [Table 1-5] [Table 1-6] [Table 1-7] [Table 1-8] [Table 1-9] [Table 1-10] [Table 1-11] [Table 1-12] [Table 1-13]
[0146] As a third line of evidence, 10 patient-derived xenograft (PDX) models and 4 normal epithelial models A dataset of small RNA profiles from unmatched samples was analyzed. As shown, these oncRNAs are almost absent in normal samples but are present in PDX models. By summing the expression of all 201 oncRNAs across all samples, A simple classification that perfectly separates normal and PDX profiles Taken together, these findings suggest that the expression of ribosomal proteins is essential for the development of breast cancer. We establish the existence of a large pool of oncRNAs that are strongly associated with cancer.
[0147] Example 3. Identification of T3p, an oncRNA associated with breast cancer progression In addition to the aforementioned cell lines, we selected for high metastatic potential in vivo in immunodeficient mice. Highly metastatic cell lines that have been identified have also been profiled (1, 15). When the expression of oncRNAs in highly metastatic cells was compared to their low metastatic parental lines, One oncRNA was observed whose levels were significantly increased in the 40-nucleotide The oncRNA of the otide is 3' to the TERC gene, which encodes the RNA component of telomerase. Therefore, this previously unknown small RNA A was named T3p because it is the 3' RNA of TERC. Analysis of a previously published dataset (7) demonstrated high expression of T3p in highly metastatic cells. This upregulation of T3p expression in metastatic cells was further confirmed by qPCR (Fig. 3C). This was confirmed by (Figure 3C).
[0148] Next, it was investigated whether increased T3p expression contributed to the pathogenesis of the underlying disease. Approximately 400 from BRCA (The Cancer Genome Atlas, breast cancer) Matched normal and breast cancer tumor tissue samples were analyzed, and T3p expression was found to be highly cancer-specific. It was found that there was a significant difference (Figure 3D). Next, TCG with approximately 1000 tumor samples was performed. The entire A-BRCA dataset was included. Consistent with its identity, T3p was not detected in the majority of normal samples, but It was detected at relatively high levels in tumor biopsies and, more importantly, in highly metastatic cell lines. Consistent with the high expression of T3p in rhesus monkeys, there was a highly significant association between patient survival and T3p expression. Furthermore, as shown in Figure 3G, T3p expression was significantly increased in TCGA-B cells. Normal samples, stage I, and stage II or III in the RCA dataset The detection of any level of T3p in tumor samples is indicative of breast cancer and The T-cell response in clinical breast cancer samples was strongly associated with both shorter and more severe overall survival (Figure 4A and Figure 4B). Higher expression of 3p also strongly correlated with advanced stage breast cancer (Figure 3E). Stratification of these cancer samples by HER2 and HER2 status was consistent with T3p levels. Strong association with strogen receptor, progesterone receptor, or HER2 receptor expression Consistent with this finding, PD in breast cancer compared with normal epithelial tissue was not observed (Figure 4C). Increased expression of T3p was also observed in the X model (Figure 4D). established oncRNA T3p as a cancer-specific biomarker with high prognostic value do.
[0149] Example 4. T3p acts as a broad regulator of gene expression in breast cancer cells The strong association between T3p expression and breast cancer progression from multiple independent data sets supports the conclusion that T3 This raises the possibility that p plays a direct and functional role in breast cancer progression. To elucidate the function of T3p, it was investigated whether modulation of T3p expression levels resulted in modulation of the outcome. To this end, highly metastatic MDA-LM2 cells were treated with antisense oligonucleotides targeting T3p. by transfection with LNA or scrambled LNA as a control. Gene expression profiling was then performed to determine whether T3p was silenced. We measured the genome-wide regulatory impact of T3p silencing. Surprisingly, thousands of T3p silencing significantly alters the cellular gene expression profile, affecting a wide range of genes. Significant changes were observed in many established transcription factors, including small non-coding RNAs. However, the effects of LNAs targeting T3p are comparable to those of post-regulatory factors (7, 16). also affect TERC function, which may account for the observed changes in gene expression. The full-length TERC transcript remains a potential confounding factor because it may be possible that Two independent methods were used to distinguish between the two. First, a scrambling LNA In addition, antisense LNAs against the 5' end of full-length TERC and T3p were also used. As shown in Figure 1, the gene expression changes caused by anti-T3p LNA were Whether a scrambled LNA or an anti-full-length TERC LNA is used as a reference This observation supports the conclusion that inhibition of full-length TERC is mediated by T3p inhibition. Furthermore, these findings suggest that ATP does not induce the same dramatic regulatory changes as ATP. To strengthen the relationship, gain-of-function experiments were also performed. MDA-MB-231 parental breast cancer cells were cultured using scrambled oligonucleotides as a control. Transfection with oligonucleotides and then gene expression profiling was performed. Similar to the LNA experiments, significant changes in the distribution of cellular gene expression were observed. Notably, these gene expression changes were similar to those observed in loss-of-function LNA experiments. This was generally anti-correlated with anti-T3p LNA and T3p mimics (Figure 6A). This is consistent with the expectation that α should induce opposing changes in gene expression. These observations establish T3p as a broad regulator of gene expression in breast cancer cells. do.
[0150] Example 5. T3p promotes breast cancer metastasis Broad regulatory effects of T3p on gene expression and its association with metastasis and breast cancer Given the association with poor survival in mice, we next investigated the role of this oncRNA in metastasis in vivo. To test this hypothesis, we investigated whether highly metastatic MDA-L M2 cells were transfected with anti-T3p LNA and these cells were transformed into immunodeficient mice. Metastatic lung colonization assays were performed by injecting the mice into the venous circulation. In vivo imaging was used to study the time course of metastatic lung colonization of these cells. The effect of T3p inhibition on T3p expression was measured. As shown in Figure 6B, anti-T3p LNA Cells transfected with α-glucan significantly attenuated their lung colonization ability. Macroscopic histological examination also revealed that the lungs of mice injected with T3p-LNA transfected cells As shown in Figure 6C, the results revealed significantly fewer visible metastatic nodules in the 100% PO4+ / 2 ... Visual metastatic nodules were counted in three mice from each cohort. Representative H&E-stained lung sections from the study are also shown, along with median counts. reveals the previously unknown functional role of T3p in driving breast cancer metastasis. Strongly support the role.
[0151] Example 6. Specific oncRNAs are sorted into the exosome compartment The exosome compartment contains small molecules such as small non-coding RNAs and tRNA fragments. It has previously been reported as a biologically relevant destination for dna RNA (28). Analysis of exosome small RNA-seq data from MDA-MB-231 cells (29 ) demonstrated that a large number of annotated oncRNAs in this study are exogenous to cancer cells. In comparison, these cytoplasmic vesicles were found to be highly resistant to ATP (Fig. 7A). Only a few of these oncRNAs were detected in exosome samples from HUVEC cells. For example, T3p was expressed in MDA-MB-231 cells but not in HUVEC cells. These observations support the idea that exosomes contain small molecules called R This prompted the next series of experiments aimed at profiling NA. In this study, small RNAs were isolated from exosomes secreted by eight breast cancer cell lines and HMECs. Small RNA sequencing of this material revealed 201 annotated oncRNAs. Of the A's, approximately two-thirds were found in exosomal RNA from one or more of these breast cancer lines. We found that IL-16 was detected in IL-16 cells but not in HMECs (Fig. 7B). Interestingly, T3p was detected in 5 of the 8 cell lines.
[0152] To assess whether oncRNAs are also present in the circulating RNA population, we analyzed breast cancer patient-derived We reanalyzed a collection of RNA-seq data generated from RNA isolated from serum of (31) The baseline included data collected from the serum of 11 healthy individuals. As shown in Figure 7C, the majority of oncRNAs were circulating RNAs derived from breast cancer patients. Although detectable in samples, it was generally absent in healthy individuals. This observation is consistent with the ncRNAs may be used for cancer fingerprinting using liquid biopsies To assess this possibility, a linear model was applied to the collected data from the cell line. We trained on the exosomal oncRNA dataset (Figure 7B) and used it to generate circulating The trained model predicted the classification of RNA profiles in 11 / 11 healthy individuals (Figure 7C). Normal samples and samples from 31 / 40 cancer patients were successfully assigned (AUC: 0.96 , AUPRC: 0.99, and ACC: 0.82). For example, T3p alone is associated with breast cancer The expression levels were significantly different between the control and healthy volunteers (Figure 7C and Figure 8B Given the success of this simple classifier, a more generalizable machine learning approach is being developed, known as TCGA- Train a gradient boosting classifier on 201 oncRNAs from the BRCA dataset This model, trained on the TCGA data, was then compared with the circulating hypothetical data in Figure 7C. The classifier was tested on 11 / 11 healthy samples and 37 / 4 0 patient samples were successfully classified (AUC: 0.976, AUPRC: 0.993, and Based on these results, we hypothesized that circulating oncRNA Detection should provide highly specific and robust information regarding the potential presence of cancer. The list of 67 identified circulating oncRNAs is shown in Table 2 below. vinegar. [Table 2-1] [Table 2-2] [Table 2-3] [Table 2-4] [Table 2-5]
[0153] Finally, from the 201 identified oncRNAs, the following oncRNAs shown in Table 3 were identified: Which has the strongest ability to predict the presence of breast cancer in subjects by analysis of serum samples? It was found that... [Table 3-1] [Table 3-2]
[0154] The current hypothesis of breast cancer development and progression is that abnormalities result in increased selection of oncogenic phenotypes. As a result, the development of cancer therapeutics and diagnostic agents is Targeting these pathways to reduce the ability of these cancer cells to survive, divide, or spread In an embodiment of the present invention, the cancer cells express cancer-specific regulatory pathways. It was proposed that the brain can evolve to create new cells. Systematic and unbiased discovery steps targeting cancer cell lines and HUMEC 201 expressed in breast cancer cells but nearly undetectable in normal tissues A group of RNA species, collectively termed orphan non-coding RNAs, was identified. These RNA molecules represent novel pathways that cancer cells can use to create novel regulatory circuits. This provides a diverse pool of potential regulatory factors. To answer this question, low- and high-metastatic cells were compared. One of these RNAs, tagged with α-glucan, was identified in both the cell line model and the clinical dataset. Finally, the present invention has been shown to be strongly associated with metastatic progression in the presence of IFN-γ. Examples include the fact that oncRNAs can be detected in the circulating and exosomal compartments. Indicates that.
[0155] These findings may contribute to understanding how cancer progression and tumors evolve and regulate their progression on the way to metastatic spread. It offers a new paradigm for how pathways can be rewired. The results also suggest a novel tool for breast cancer detection and monitoring that may complement current methods. Current screening methods for breast cancer, including mammography and ultrasound, are low-resolution Given that they provide limited detection signals due to Other strategies in development for early cancer detection involve extracting circulating tumors from patients' serum. Liquid biopsy, which attempts to detect biological markers of cancer, including tumor cells and DNA. We have focused on the high abundance of secreted exosomes in the serum of patients and on The cancer cell specificity of cRNA provides a more reliable method for early detection or screening. In other words, the research described herein may provide a significant enhancement to our repertoire for The study found that oncRNA acts as a digital fingerprint of potential tumors – i.e. , supporting the idea that each marker is either detected or not detected.
[0156] Although the examples described herein have mostly focused on the role of T3p in breast cancer metastasis, The techniques and concepts presented herein are generalizable and applicable to several cancers. Taken together, these findings support further investigation of cancer-specific RNA distribution. and oncRNA research will lead to alternative treatments and diagnostic methods for many cancer types.
