Embodiment Construction

[0020] The present invention will be further illustrated by specific examples of the methylation detection of CDKN2A gene fragments in the blood of tumor patients and normal people.

[0021] 1) Genomic DNA extraction and bisulfite treatment.

[0022] The DNA extraction kit was used to extract the total genomic DNA of the blood sample, and the purity and concentration of the DNA solution were detected by agarose gel electrophoresis and ultraviolet-visible light spectrophotometry. Take a certain amount of genomic DNA with a known concentration and treat it with a bisulfite conversion kit to convert unmethylated cytosine (C) into uracil (U), while methylated cytosine remains constant.

[0023] 2) The following describes the specific design method of PCR primers for CDKN2A gene fragments of the present invention as follows:

Abstract

The invention discloses a CDKN2A gene fragment and application of the primers of CDKN2A gene fragment in diagnosing tumors.By designing an upstream and downstream primer pair, the specific CDKN2A gene fragment is determined, the gene fragment shows remarkable high DNA methylation in tumor patients while showing low DNA methylation in normal people, and statistic differences exist between DNA methylation of tumor patients and that in normal people.Occurrence and development of tumors are tracked with the level changes of DNA methylation of the gene fragment, and thus a novel biomarker is provided for diagnosis, treatment effect monitoring and prognosis improvement judgment of tumors.

Description

Technical field [0001] The invention belongs to the field of gene technology, and specifically relates to the application of CDKN2A gene fragments in the fields of tumor clinical diagnosis, curative effect monitoring and prognosis judgment. Background technique [0002] Tumor is a common and frequently-occurring disease. At present, malignant tumors have become one of the most serious diseases that endanger human health. The mortality rate of malignant tumors ranks second only to cardiovascular system diseases, and is gradually increasing, consuming a lot of medical resources. Most tumors are caused by the gradual accumulation and interaction of genetic mutations and epigenetic changes, and their development is slow. If they can be detected at an early stage, surgical resection and radical treatment can be performed. Therefore, early tumor screening is of great significance. Existing tumor screening methods include colonoscopy, stool sDNA examination, serum carcinoembryonic anti...
