A method and system for quantifying the relative abundance of gene transcripts in a biological sample. One embodiment of the method generates high-throughput sequence-specific analysis of multiple RNAs or their corresponding cDNAs (gene transcript imaging analysis). Another embodiment of the method produces a gene transcript imaging analysis by the use of high-throughput CDNA sequence analysis. In addition, the gene transcript imaging can be used to detect or diagnose a particular biological state, disease, or condition which is correlated to the relative abundance of gene transcripts in a given cell or population of cells. The invention provides a method for comparing the gene transcript image analysis from two or more different biological samples in order to distinguish between the two samples and identify one or more genes which are differentially expressed between the two samples.

The invention discloses a DNA and protein level mutation analysis method. The method comprises the steps of 1, reading a gene mutation file, and formatting the file into a standard name; 2, indexing a transcript sequence, gene information and gene transcript annotation information, thereby forming an amino acid codon corresponding relationship table; judging a mutation level and a mutation mode, and judging whether a mutation name is protein level mutation, genome DNA level mutation or CDS code area mutation; and 4, entering different level mutation mapping processes according to a judging result of the step 3, thereby obtaining mapping relationships of three mutation names. According to the method, the mapping relationships of various mutation names are output by carrying on phenotypic correlation gene mutation and polymorphic sites mined from literatures, thereby finishing annotating correspondence between pathogenic variation mined from the literatures, and gene mutation and polymorphic sites identified by sequencing.

The invention provides a gRNA for targeting a pathogen gene RNA, and the invention also provides a human pathogen gene detection method and detection kit based on a clustered regularly interspaced short palindromic repeat (CRISPR)-C2c2 system. The detection method combines the advantages of the gRNA in targeting to recognize a pathogen gene transcript RNA (target RNA sequence) and the characteristic that when the CRISPR-C2c2 complex detects the target RNA sequence, the complex cleaves a reporting RNA with a detection marker to release detectable signals, the CRISPR-C2c2 system is applied to pathogen gene detection, and has high sensitivity and high accuracy. The detection method and the detection kit have great commercial application value.

A multi-analyte composition for the diagnosis of lung cancer or lung disease comprises a ligand selected from a nucleic acid sequence, polynucleotide or oligonucleotide capable of specifically complexing with, hybridizing to, or identifying an mRNA gene transcript from a mammalian blood sample, and an additional ligand selected from a nucleic acid sequence, polynucleotide or oligonucleotide capable of specifically complexing with, hybridizing to, or identifying an miRNA of a gene from a mammalian blood sample. Each ligand and additional ligand binds to a different gene transcript or miRNA and the gene transcripts and miRNA identified form a characteristic profile of a stage of lung cancer or lung disease. Methods of using this composition for diagnosis and evaluation and methods for developing such compositions are described.

Methods and compositions are provided for diagnosing ectopic pregnancy in a mammalian subject by detecting changes in expression of ISM2, ADAM12, PST1, PSG7, PST11, PSG9, PSG2 and other genes identified therein, including combinations thereof. A selected gene, gene transcript or protein/peptide expression product, or profiles or signatures formed by combinations of same, detected in a biological fluid of a subject, enables comparison of the corresponding genes, proteins or profiles from that of a reference or control having a normal intrauterine pregnancy. Detection of characteristic changes in the gene profile or protein expression signature of the subject is correlated with a diagnosis of ectopic pregnancy. Various compositions for use in such diagnosis include PCR primer-probe sets or ligands, labeled or immobilized, which are capable of detecting the changes in expression or translation of these targets.

The present invention discloses a novel single nucleotide polymorphism (SNP) in the isolated 5′ tandem repeats of the thymidylate synthase (TS) gene and methods for its use. The novel SNP, located in the 12th nucleotide of a 28 bp third tandem repeat (3R) of the TS gene, substitutes a C for a G, and is the variant form of the repeat. Subjects with the wild-type form of 3R have greater transcription of the TS gene than subjects with the variant form. The invention also reveals that a six base pair deletion in the 3′ region of TS (−6 bp/1494) indicates mRNA instability and thus reduced production of TS. In diseased tissue, such as cancer, reduced production of TS is beneficial because it prevents the cancerous cells from growing and spreading. Analysis of either polymorphism or both together allows for prediction of a subject's response to chemotherapeutic and anti-cardiovascular disease treatments because both diseases are related to TS levels in a subject.

Using an RT-PCR platform, detection of gene transcripts highly expressed in prostate tissue and expressed in peripheral blood mononuclear cells (PBMC) from patients with mCRPC can provide a more reliable and robust prediction of poor overall survival than that of CTC enumeration in mCRPC. Disclosed is the identification of five genes, KLK3, KLK2, HOXB13, GHRL2 and FOXA1, the detection of two (2) or more transcripts of which predicts overall poor survival. The test is performed on blood samples that have been collected in collection tubes that stabilize intracellular RNA, require minimal on-site processing and can be easily stored and shipped for subsequent extraction of total RNA from whole blood for RT-PCR.
