Problems solved by technology

A number of current studies have shown that the polymorphism of this site will weaken the performance of the transcription factor complex that ERCC2 participates in, thereby reducing the ability to repair DNA damage, and the ability of transcription factors will also decrease at the same time, resulting in a series of Occurrence of diseases such as lung cancer, prostate cancer, etc.

Embodiment 1

[0029] Example 1. Use of detection kits

[0030] Step 1: Extraction of DNA template

[0031] Genomic DNA of oral epithelial cells was extracted by silica gel adsorption.

[0032] Step 2: Real-time quantitative PCR reaction

[0033] Use a fluorescent quantitative PCR detection kit that can detect susceptibility to lung cancer, which contains the following primer pairs and fluorescent probes:

[0034] Sense primer 1: 5'-TTTGCCATTCACTGTGTTGG-3' (SEQ ID NO: 1) with a Tm value of 58°C

[0035] Antisense primer 1: 5'-ATCCTTGCTGCTATCATCA-3' (SEQ ID NO: 2) with a Tm value of 54°C

[0036] Sense primer 2: 5'-TAACTGGCATCTTCACTTCT-3' (SEQ ID NO: 3) with a Tm value of 56°C

Embodiment 2

[0052] Example 2. Services that guide people to proactively prevent lung cancer

[0053] At present, Shanghai Zhujian Bioengineering Co., Ltd. has launched this service.

[0054] Step 1: DNA Extraction

[0055] The subjects were consulted before the service, and the subjects signed the informed consent and filled out the questionnaire on living and eating habits. According to the instructions in the sampling box, the oral epithelial cells were sampled with oral swabs, and the DNA of the oral epithelial cells was extracted by silica gel adsorption.

[0056] Step 2: Genotyping Assays

[0057] Using the kit provided by the invention, the SNP site No. rs1136410 on the PARP1 gene, the SNP site No. rs25487 on the XRCC1 gene, the SNP site No. rs13181 on the ERCC2 gene and the SNP site No. rs1799793 on the ERCC2 gene Fluorescent quantitative PCR detection was performed at the same time to determine the genotypes of the four SNPs loci.

Abstract

The invention discloses a regent box for detecting the susceptibility to lung cancer, comprising a specific primer and a specific fluorescent probe which are capable of synchronously detecting an rs1136410 SNP locus on an PARP1 gene, an rs25487 SNP locus on a XRCC1 gene and an rs13181 SNP locus and an rs1799793 SNP locus on an ERCC2 gene, and common components for fluorescent quantitative detection of PCR. The reagent box of invention predicts the susceptibility to lung cancer of an individual by detecting the genotype of genes on the SNP loci of the PARP1 gene, the XRCC1 gene and the ERCC2 gene of the individual.

Description

technical field [0001] The present invention relates to a kit for detecting disease susceptibility, especially a kit for detecting susceptibility to lung cancer. , PARP1, also abbreviated as ADPRT), X-ray repair cross-complementing gene 1 (XRCC1) and excision repair complex 2 (Excision Repair Cross-complementing Rodent Repair Deficiency, Complementation Group 2, ERCC2) single nucleotide polymorphism sites (SNPs) to predict individual susceptibility to lung cancer. Background technique [0002] Primary bronchial lung cancer, referred to as lung cancer, is one of the most common malignant tumors in the world and a serious threat to human health and life. Tumor cells originate from the bronchial mucosa or glands, and often have regional lymph node and hematogenous metastasis. In the early stage, respiratory symptoms such as irritating cough and blood in the sputum are often present. The speed of disease progression is related to the biological characteristics of the cells. ...
