Embodiment 1

[0082] This embodiment provides a kit for auxiliary diagnosis of colorectal cancer or colorectal adenoma, which includes: detection reagents for detecting methylation of colorectal cancer-related genes, wherein the colorectal cancer-related gene is the SDC2 gene, The detection reagents include a first reagent for detecting methylation of a first target region on the SDC2 gene;

[0083] The first target region is selected from any one of the following regions of the SDC2 gene: region a, region b and region c;

[0084] Among them, refer to figure 1, region a is selected from the full-length region of chr8:96493351-96493635 (hereinafter referred to as SDC2DMR1, it should be noted that, in other embodiments, region a can be selected from a partial region of chr8:96493351-96493635, whether it is the detection The full length of the chr8:96493351-96493635 region or a part of it, all belong to the protection scope of the present invention);

[0085] Region b is selected from the fu...

Embodiment 2

[0095] The kit for auxiliary diagnosis of colorectal cancer or colorectal adenoma provided in this example is basically the same as that in Example 1, the difference is that in this example:

[0096] Area a is selected from the partial area of ​​SDC2 DMR 1, specifically, refer to figure 1 , region a is selected from chr8:96493393-96493581 (named SDC2 DMR 1-a) or chr8:96493456-96493629 (named SDC2 DMR 1-a1);

[0097] Area b is selected from the partial area of ​​SDC2 DMR 2, specifically, refer to figure 1 , region b is selected from chr8:96493701-96493858 (named SDC2 DMR 2-b) or 96493770-96493900 (named SDC2 DMR 2-b1);

[0098] Area c is selected from the partial area of ​​SDC2 DMR 3, specifically, refer to figure 1 , region c is selected from chr8:96494006-96494166 (named SDC2 DMR 3-c) or chr8:96494140-96494327 (named SDC2 DMR 3-c1).

[0099] Furthermore, the kit of this embodiment also includes primer pairs and fluorescent probes for detecting the above target regions, and...

Embodiment 3

[0105] This embodiment provides a kit for the auxiliary diagnosis of colorectal cancer or colorectal adenoma, which includes: a detection reagent for detecting the methylation of colorectal cancer-related genes, wherein the colorectal cancer-related gene is the TFPI2 gene, The detection reagents include a second reagent for detecting methylation of a second target region on the TFPI2 gene;

[0106] Wherein, the second target region is selected from any one of the following regions of the TFPI2 gene: region d and region e;

[0107] Among them, refer to figure 2 , region d is selected from the full-length region of chr7:93890026-93890319 (hereinafter referred to as TFPI2 DMR1, it should be noted that, in other embodiments, region d can be selected from a partial region of TFPI2 DMR1, whether it is to detect chr7: The entire length of the 93890026-93890319 area or a part of it, all belong to the protection scope of the present invention);

[0108] Region e is selected from the...

Abstract

The invention discloses application of a detection reagent for detecting methylation of genes related to colorectal cancer and a kit, and relates to the technical field of gene detection. The kit comprises the detection reagent used for detecting methylation of the genes related to colorectal cancer, conducts methylation detection on specific areas in the genes SDC2 and TFPI2, takes the methylation detection result of the areas as a basis for auxiliary colorectal cancer diagnosis, is higher in sensitivity and specificity and provides a more accurate and reliable reference basis for early screening, diagnosis and the like for colorectal cancer or colorectal adenoma.

Description

technical field [0001] The invention relates to the technical field of gene detection, in particular to the application and kit of detection reagents for detection of colorectal cancer-related gene methylation. Background technique [0002] Colorectal cancer is the third most common malignancy in the world. In recent years, the incidence of colorectal cancer in China has been increasing year by year. It is estimated that there are about 400,000 new cases each year, ranking second among malignant tumors of the digestive system in my country. Colorectal cancer usually develops slowly from precancerous polyps through a series of genetic and epigenetic alterations as well as histological and morphological changes, and most colorectal tumors grow slowly, remain silent, or are asymptomatic until they reach the A certain size or stage of development. Therefore, colorectal cancer is an ideal target for intervention through screening. The 5-year survival rate of patients with earl...
