Description

Probe composition for detecting 6 Chinese high-incidence cancers

Technical Field

The invention relates to a cancer gene methylation detection composition, in particular to a probe composition for specifically identifying a DNA sequence after Bisulfite (bisufite) treatment, and an application of detecting free DNA methylation level changes of 6 tumors such as esophageal cancer, gastric cancer, colorectal cancer, lung cancer, liver cancer and pancreatic cancer based on a high-throughput sequencing (NGS) method.

Background

The high-throughput sequencing (NGS) technology, which is a revolutionary innovation in the field of modern genomics research, can simultaneously perform sequence analysis on dozens to millions of DNA molecules, which marks the arrival of the post-genome era. By controlling the sequencing depth, different targets such as de novo sequencing and re-sequencing can be realized, and the sequences of genome, transcriptome and methylation set can be analyzed through different pre-treatment.

The current clinical gene detection technologies mainly include Polymerase Chain Reaction (PCR), Fluorescence In Situ Hybridization (FISH) and gene chip technologies. The PCR instrument has low equipment price, high sensitivity, simple and quick operation and high clinical popularization, but is limited by technology and can only detect a few genes simultaneously. FISH sensitivity is high, but the manipulation difficulty is large. The gene chip has higher flux than the former two, and can detect a large number of genes simultaneously. But the method is limited in that only known genes or variations can be detected, the accuracy is low, and the false positive is high. The NGS technology has the characteristics of high flux (simultaneously detecting a large number of known and unknown genes and variations), accurate result (higher accuracy than a gene chip), high detection speed, low detection cost shared by each gene and the like, and is gradually applied to the fields of clinical disease detection, monitoring and the like. With the further reduction of the sequencing cost in the future, the NGS will inevitably replace gene chips and other high-throughput technologies step by step.

Due to the high overall price of current conventional whole genome sequencing, the final price is overwhelming for the consumer if the sequencing depth is increased in order to detect rare variations. Therefore, the capture sequencing of the target sequence becomes a mainstream choice, and the technology is to design a capture probe aiming at a genomic region of interest according to the detection requirement, enrich the target fragment DNA by the hybridization complementary principle, and perform the NGS detection subsequently. The strategy can be flexibly customized according to the purpose of research or detection, only a small number of gene regions are selected, the sequencing depth is increased, the variation condition of the target region can be effectively found, and the method has high sensitivity and accuracy.

During the development and progression of cancer, genetic information can undergo a series of changes, including mutations, insertions/deletions of DNA, structural variations of chromosomes, copy number variations, and alterations in epigenetic information. During the progression of cancer, variations in DNA sequence occur randomly, and can lead to the development of malignant tumors only when the variations occur in key growth control genes. Most gene expression abnormalities are due to epigenetic changes, usually changes in the level of DNA methylation. Research shows that the change of gene methylation level is earlier than gene variation, and the change of gene methylation is tracked and detected, so that the generation of cancer can be predicted earlier. In recent years, with the development of genomics, epigenomes of over 30 cancers have been studied. The results show that although DNA methylation is not predominant in every cancer, it is doubtful that changes in the pattern of gene methylation modification alter the propensity of cells to develop and the phenotype of tumors, thereby having a significant impact on the development of most cancers.

The genomic map of cancer (TCGA) in 2018 early published 27 summarized analyses, which have so far made the most comprehensive pan-cancerous genomic analysis of more than 30 cancer data over a period of ten years. After analysis by integrating various data such as chromosomal variation, DNA methylation, RNA and protein, it was found that 33 anatomical cancers can be divided into 28 subtypes according to molecular characteristics. A certain molecular subtype will include 26 cancers in the classical sense. This result suggests that cancers derived from different organs share common molecular characteristics. Meanwhile, cancers derived from the same organ may have different genomic profiles. Therefore, in the near future, the development of cancer screening and diagnosis markers will certainly introduce more pan-cancer concepts, and the markers can be used for researching cancers not only in anatomical levels, but also in molecular levels, and developing pan-cancer markers capable of covering certain molecular typing.

Liquid biopsy is a mode of in vitro diagnosis, non-invasive blood detection is adopted, Circulating Tumor Cells (CTC) or circulating tumor DNA (ctDNA) released from tumors or metastatic foci to blood can be monitored, the technology can effectively reduce the damage caused by invasiveness, can realize sampling of all parts of tumors and all metastatic foci, overcomes tumor heterogeneity (the current adopted standard tissue biopsy can only reflect the characteristics of a certain part of tumors), realizes real-time monitoring, has higher sensitivity, even can predict the diseased part through genome information, and can effectively prolong the life cycle of a patient. According to the advantages, the liquid biopsy can be used for early diagnosis, auxiliary staging, prognosis and recurrence monitoring of tumors, medication guidance and the like. The most commonly used free DNA for liquid biopsy today.

Free DNA (cfdna) is free and extracellular partially degraded endogenous DNA present in circulating blood. Research shows that during the development of tumor tissue, after tumor cells are apoptotic, DNA is released into plasma, and after degradation, free tumor DNA (ctDNA) is formed. The molecular genetic characteristics (such as gene mutation, microsatellite instability, tumor suppressor gene promoter methylation and the like) of the CtDNA are consistent with those of tumor tissue DNA. In early screening and detection of multiple cancers, the method is simpler and more convenient to collect peripheral blood than other clinical detection means, is easy to popularize to the basic level, and is easier to be accepted by asymptomatic people due to the non-invasive characteristic. Therefore, the detection of the change of the ctDNA methylation level in the plasma can become one of the important means for the early screening and diagnosis of multiple cancers.

By using a target sequence capture technology in combination with NGS to monitor the variation of cfDNA and the change of methylation level, the application of early tumor screening, susceptibility gene monitoring, companion diagnosis, personalized medicine application, prognosis monitoring and the like can be realized. At present, various companies at home and abroad push out different scales, and some of the panel has obtained approved literature numbers of FDA or CFDA aiming at cancer detection panels of different application scenes. For example, Foundation one CDx proposed by Foundation Medicine covers 324 genes, IMPACT proposed by the memorial Schlumberger Katelin cancer research center (MSK) covers 468 cancer-related genes, a "human EGFR/ALK/BRAF/KRAS gene mutation joint detection kit" proposed by stone burning Medicine, a "human EGFR, KRAS, BRAF, PIK3CA, ALK, ROS1 gene mutation detection kit" proposed by Norway of causing, and the like. Kun distant gene also introduced the product "Changle si" in 2018 for detecting methylation level of colorectal cancer.

Definition of

Unless specifically defined elsewhere herein, all other technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this document belongs.

The probe is single-stranded or double-stranded DNA with the length of tens to hundreds or even thousands of base pairs, and can be combined (hybridized) with complementary non-labeled single-stranded DNA or RNA in a sample to be detected by hydrogen bonds to form a double-stranded complex (hybrid) by utilizing the denaturation and renaturation of molecules and the high accuracy of base complementary pairing. After washing off the probe which is not coupled, the result of hybridization reaction can be detected by a detection system such as autoradiography or enzyme-linked reaction. Herein, the region to which the probe complementarily binds or hybridizes is a specific target region. Multiple probes are combined into a probe composition.

A cancer specific region is one in which the methylation level of the region is significantly different in a small percentage of cancer species as compared to normal control tissue.

Pan-cancer specific regions refer to regions of significant difference in methylation levels in most cancer species compared to normal control tissues.

A tissue-specific region is one in which the methylation level of the region is significantly different in a particular tissue as compared to other tissues.

DNA methylation refers to the methylation process of the 5 th carbon atom on cytosine in CpG dinucleotide, and is an important epigenetic mechanism which can be inherited to new filial generation DNA along with the DNA replication process under the action of DNA methyltransferase as a stable modification state. Aberrant methylation includes hypermethylation of cancer suppressor genes and DNA repair genes, hypomethylation of repeat DNA, loss of imprinting of certain genes, which is associated with the development of a variety of tumors.

In a specific embodiment herein, the detection method enriches cfDNA by means of hybrid capture and detects methylation sites highly associated with cancer using NGS technology. Covers 6 malignant tumors (esophageal cancer, gastric cancer, colorectal cancer, lung cancer, liver cancer and pancreatic cancer) with the highest incidence rate in China. Finally, information is provided for early screening and early diagnosis of multiple cancers according to the detection of the gene methylation change level in the cfDNA of the blood plasma.

The application also provides a method for simultaneously detecting the change of the methylation level of the 6 cancers by using the kit.

In particular, the present application relates to a method for the in vitro detection of 6 cancers in a subject, comprising the steps of: collecting a subject sample; extracting and purifying DNA in the sample; constructing a DNA library for sequencing against the purified DNA sample; transforming said constructed DNA library with bisulfite; pre-PCR amplifying the bisulfite-converted DNA library; performing hybridization capture on the sample subjected to the pre-PCR amplification by using the probe composition; amplifying the product obtained after hybridization capture by utilizing PCR; performing high-throughput second-generation sequencing on a product obtained after hybridization and capture after PCR amplification; analyzing the sequencing data to determine the methylation level of the sample; interpreting the patient's condition based on the methylation level of the sample.

In particular, the subject is suspected of having cancer. In particular, the sample taken from the subject is a plasma sample. In particular, the conversion is treated with bisulfite.

Specifically, the probe composition comprises: 2 probes targeting pan-cancer specific regions, n probes targeting cancer specific regions, and m probes targeting tissue specific regions. The probe composition comprises: hypomethylated probes that hybridize to the cancer specific, pan-cancer specific, and tissue specific regions that are bisulfite converted without CG methylation, and hypermethylated probes that hybridize to the cancer specific, pan-cancer specific, and tissue specific regions that are bisulfite converted CG all methylation. Each probe in the probe composition has a length of 40-60 bp. For example, each probe in the probe composition has a length of 45 to 56bp, preferably 50 to 56bp, and more preferably 50 bp.

Specifically, n probes in the probe composition target the cancer specific region, wherein n is any integer selected from 1-192; wherein the cancer specific region is selected from the group consisting of Seq ID No.: 1-62. M probes in the probe composition target the tissue specific region, wherein m is an integer selected from any of 1-116; wherein the tissue specific region is selected from the group consisting of Seq ID No.: 65-67, 70-74, 76, 79, 81-83, 87-92, 97-105, 108, 111-118. The hypomethylated probes include probe Seq ID No.: any of 119-215, probes Seq ID No.: any of 216-217, and a probe Seq ID No.: 218-. The hypermethylated probes include probe Seq ID No.: any of 277-373, probe Seq ID No.: 374-375, and a probe Seq ID No. targeting a tissue-specific region: 376-, 378-, 381-, 387-, 388-, 391-, 393-, 395-, 399-, 404-, 409-, 418-, 421-, 424-, 434.

In particular, the interpretation comprises the following steps: (1) comparing the pan-cancer specific region database and performing interpretation to confirm whether the subject has cancer; (2) comparing the cancer specific region database, and judging to confirm that the cancer suffered by the subject is one of several suspected cancers; (3) comparing the tissue specific region database, and performing interpretation to confirm the cancer part of the subject. The step (1) comprises the following interpretation: judging the pan-cancer specific region Seq ID No.: 63, and the pan cancer-specific region Seq ID No.: 64 is greater than or equal to 60%, the patient is read as having cancer. The step (2) comprises the following interpretation: the patient is judged to have any one of the tissue-specific cancers if the methylation level of the region targeted by n1 probes among the n probes targeting the cancer-specific region is equal to or greater than the respective threshold value, and n 1/n.gtoreq.20%, preferably n 1/n.gtoreq.30%. The step (3) comprises the following interpretation: and if the methylation level of the region targeted by the m1 probes in the m probes targeting the tissue-specific region is greater than or equal to the respective threshold value, further analyzing the tissues targeted by the m1 probes greater than or equal to the respective threshold value and counting the number of the probes greater than or equal to the threshold value in each tissue, and judging that the tissue of the patient suffering from the cancer is the tissue with the highest number of the probes with the methylation level greater than or equal to the threshold value. The threshold for methylation for each target region is also given in table 1 below.
