Abstract

The invention discloses a kit and a method for detecting the mutation of a TERT promoter through a pyrosequencing method. The mutation of the TERT promoter specifically refers to mutations of -124bp 1295, 228C>T and -146bp 1259, 250C>T on the upstream of the promoter. The kit comprises a PCR (Polymerase Chain Reaction) buffer solution, a TaqDNA polymerase, a primer, a template DNA, a pyrosequencing kit, a magnetic bead, a combined buffer solution, a washing buffer solution, an annealing buffer solution and a denaturation buffer solution. The kit can accurately efficiently detect the mutation of the TERT promoter at high throughput, so that the evidence is provided for the early diagnosis and screening of the thyroid cancer.

Description

technical field [0001] The invention belongs to the field of molecular biology, relates to medicine and biotechnology, in particular to a kit and a method for detecting TERT promoter mutation by pyrosequencing. Background technique [0002] Telomeres are small nucleoprotein structures at the ends of linear chromosomes that maintain genome stability by preventing DNA fusion and degradation. In normal cells, telomeres gradually shorten with cell mitosis, thereby regulating cell aging and apoptosis. However, in cancer cells, telomerase is activated and continuously expressed, maintaining the length of telomeres and making tumor cells immortal. Telomerase is a ribonucleoprotein that uses its own RNA as a template to synthesize telomere DNA, add it to the end of chromosomes, and extend telomeres. Telomerase is highly expressed in a variety of tumor cells and plays an important role in the proliferation and differentiation of cancer cells. Inhibiting the activity of telomerase c...
