Description

Technical Field

[0001] This invention belongs to the field of bioinformatics technology, specifically relating to a method, apparatus, equipment, and storage medium for assessing the public value of a neotumor antigen. Background Technology

[0002] Cancer is caused by the accumulation of mutated genes, some of which may lead to the production of new proteins called neoantigens. Neoantigens possess high immunogenicity and have long been considered ideal targets for tumor immunotherapy. However, due to limitations in drug development cycles and the existence of heterogeneous clones within cancer tissue, most neoantigens derived from random "passenger gene" mutations often show poor therapeutic efficacy. Conversely, neoantigens generated from driver gene mutations typically maintain high clonal conservatism, exhibiting more stable therapeutic potential. If a neoantigen generated from a hotspot mutation in a driver gene successfully binds to a common HLA allele, this type of cancer-specific epitope will be shared among cancer patients, forming a "public" neoantigen. Compared to individual patient-specific neoantigens, public neoantigens have greater clinical translational value due to their tumor specificity, clonal conservation, and widespread presence in specific patient populations, enabling more patients to benefit from this therapy. To date, only a few public neoantigens have been publicly disclosed, reflecting that current assessment methods based on the frequency of missense mutations in large-scale disease genes and class I HLA binding ability are not yet effective in evaluating neoantigen value, resulting in poor suitability of the screened neoantigens. Summary of the Invention

[0003] The purpose of this invention is to provide a method, apparatus, device, and storage medium for assessing the public value of tumor neoantigens, which can effectively assess the value of neoantigens and screen out more suitable neoantigens.

Furthermore, the terms "comprising" and "having," and any variations thereof, as used herein, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such processes, methods, products, or apparatus.

[0049] This invention discloses a method for assessing the public value of tumor neoantigens, which can be implemented through computer programming. The method can be executed by electronic devices such as computers, laptops, and tablets, or by a public value assessment device for tumor neoantigens embedded in an electronic device; this invention does not limit this to any particular type. To facilitate understanding of this invention, specific embodiments will be described in more detail below with reference to the accompanying drawings.

[0050] like Figure 1 As shown, the method includes the following steps 110-160:

[0051] 110. Obtain pan-cancer sample mutation data, and perform missense mutation analysis on the pan-cancer sample mutation data to obtain multiple missense mutation sites.

[0052] Missense mutation analysis includes: calculating the missense mutation frequency of each mutation site in the pan-cancer sample mutation data, and screening mutation sites whose missense mutation frequencies reach a first specified proportion to be identified as missense mutation sites. The first specified proportion is a preset value, such as 0.2% or 0.3%.

[0053] 120. Multiple missense mutation sites were compared with the human genome to obtain multiple candidate mutation sites.

[0054] The pan-cancer sample mutation data can be downloaded and statistically analyzed from a database, which can be selected from any of the following: cBioPortal, TCGA (The Cancer Genome Atlas), GEO (Gene Expression Omnibus), COSMIC (Catalogue of Somatic Mutations in Cancer), Kaplan-Meier Plotter, or GENIE (Genomics Evidence Neoplasia Information Exchange). The human genome can be selected from any of the following versions: GRCh38 / hg38, T2T CHM13v2.0 / hs1, GRCh37 / hg19, NCBI36 / hg18, NCBI35 / hg17, or NCBI34 / hg16.

[0055] 130. Extract the nascent peptide corresponding to each candidate mutation site.

[0056] Among them, the nascent peptide is a peptide that can bind to two types of molecules of human leukocyte antigen (HLA) and induce an immune response. These two types of molecules include HLA-I molecules and HLA-II molecules.

[0057] 140. Input the newly formed peptide into the prediction model to predict the binding score between the newly formed peptide and human leukocyte antigen.

[0058] The prediction model can be a pre-built machine learning model, for example, selected from any of the following: NetMHCpan4.1, NetMHCIIpan4.1EL, Consensus, ANN 4.0, SMMPMBEC, SMM, netMHCcons. The binding score of the nascent peptide to human leukocyte antigen can be calculated based on the affinity of the nascent peptide to HLA-I and HLA-II.

[0059] 150. Calculate the common value score of each new peptide based on the number of newly generated peptides generated by the candidate mutation sites and the binding score of the corresponding newly generated peptides to human leukocyte antigens.

[0060] The public value score can be specifically the Cauchy-Schwarz score, which is calculated by taking into account the number of newly generated peptides produced by candidate mutation sites and the affinity of the newly generated peptides to HLA-I and HLA-II, based on the gene mutation frequency of different disease patient groups.

[0061] The Cauchy-Schwarz score can be calculated using the following formula:

[0062] Cauchy-Schwarz rating = [∑ i=1…n (HLAI1+HLAI2+…+HLAI n )+

[0063] ∑ i=1…n (HLAII1+HLAII2+…+HLAII n )]×VAF;

[0064] Where n represents the number of newly generated peptides from candidate mutation sites, i.e., the number of effective peptides. Effective peptides are sub-peptides that contain missense mutation sites and have a binding score with HLA. n The predicted score of the newly formed peptide and the nth HLAII is given by HLAII. n The predicted score for the newly formed peptide and the nth HLAII is given, and VAF represents the missense mutation frequency.

[0065] 160. Sort multiple newly generated peptides in descending order of public value score to obtain the sorting results, and screen out the new antigen sequences from the sorting results.

[0066] The process of sorting multiple newly formed peptides includes listing both the number and sequence of each peptide. The screening criteria for selecting neoantigen sequences from the sorting results are as follows: sequences are ordered from highest to lowest Cauchy-Schwarz score, and based on the total number of newly formed peptides, the second-highest percentage of sequences with the highest Cauchy-Schwarz scores are selected as valid neoantigen sequences. This second-highest percentage is a preset value, such as 1% or 2%.

[0067] The final selected neoantigen sequences are used to translate into clinical drugs. Comparing the neoantigen sequences with in vitro experimental validation results and clinical sequencing data allows for the validation of the Cauchy-Schwarz score. Specifically, sample data from at least one cancer patient group can be selected as the research sample, and the Cauchy-Schwarz score can be used to score and rank the research samples. The cancer types in the cancer patient group can be selected from at least one of the following: lung cancer, breast cancer, and prostate cancer.

[0068] Example 1

[0069] The overall flowchart of this embodiment is as follows: Figure 2 As shown, the process includes preliminary preparation, Cauchy-Schwarz scoring, ranking of neoantigen value scores, and verification of the screened neoantigen sequences.

[0070] (1) Preliminary preparations

[0071] Specifically, 98,478 cancer patients were selected as the study subjects, containing a total of 3,392,826 missense mutation sites. The sample population was predominantly Caucasian, followed by Asian and African populations; it covered 33 different cancer types, with lung cancer, breast cancer, and prostate cancer being the main types. A missense mutation frequency of ≥0.2% was used as the screening criterion, and 1200 missense mutation sites were obtained for subsequent research. The NetMHCpan4.1 model was used to predict the affinity of the nascent peptide with HLA-I, and the NetMHCIIpan4.1EL model was used to predict the affinity of the nascent peptide with HLA-II. The binding scores of the nascent peptide with HLA-I and HLA-II were calculated. The specific cancer population statistics are shown in Table 1 below:

[0072] Table 1. Statistics on the number of cancer cases

[0073]

[0074]

[0075] (2) Cauchy-Schwarz score

[0076] Following the prior evaluation method for common neoantigens, a total of 7 common neoantigens were screened. Using the Cauchy-Schwarz scoring method, 15 neoantigens were obtained. Besides 6 identical neoantigens, EGFR-L858R, KRAS-G13*, and TP53-G245 were found to have been validated in Phase 1 / 2 clinical trials. Four completely previously unreported novel sequences, including IDH1 and DNMT3A, were also identified.

[0077] (3) Ranking of neoantigen value scores

[0078] The newly formed peptides were sorted in descending order of their Cauchy-Schwarz scores. The sorting results are as follows: Figure 3 As shown.

[0079] (4) Result comparison

[0080] Table 2 Comparison of Cauchy-Schwarz Index Assessment Results with In Vitro Experimental Results and Clinical Test Results

[0081]

[0082]

[0083] (5) Validation of the screened new antigen sequences

[0084] like Figure 4 As shown, sequencing data from 8065 lung cancer patients, 3374 prostate cancer patients, 6439 breast cancer patients, and 494 lung adenocarcinoma patients were tested, with "checkmarks" indicating validated peptides. This finding not only validates the effectiveness of the Cauchy-Schwarz index assessment model in identifying neoantigens with broad potential but also demonstrates the universality and reliability of this assessment method across disease domains. Therefore, the results indicate that the Cauchy-Schwarz score can be used to develop common neoantigens into routine drugs for rapid cancer treatment, demonstrating the significant effectiveness of this assessment method in advancing neoantigen research and clinical application.

[0085] In summary, this invention broadly covers various cancer populations and spans multiple cancer lineages. Through a qualitative and sophisticated neoantigen value assessment mechanism, it successfully transforms highly adaptable public neoantigens into standardized, potentially clinically applicable routine drugs. This transformation process not only marks a significant leap from theoretical research to clinical practice but also brings innovative treatment strategies and methods to the field of cancer therapy.
