Abstract
PURPOSE: Tumour seriously affects people's quality of life. Colorectal cancer is a refractory tumour in digestive tract tumors. In colorectal cancer, gene expression abnormalities is the main reason for its incidence, we mainly focus on the molecular mechanism of MTAP in the development of colorectal cancer.
METHODS: The tumour tissue and its adjacent tissue samples of 50 patients with colorectal cancer were screened from July 2011 to February 2015, and the expression of MTAP was detected. Cell lines that overexpress MTAP and low expression of MTAP were constructed in colorectal cancer cell lines. The cell proliferation, invasion and migration was detected in the cells with different expression levels of MTAP. Immunohistochemistry was used to detect the expression of MTAP in liver metastasis and to investigate its clinical significance. And statistics of clinical significance.
RESULTS: Q-PCR results showed that the expression of MTAP in colorectal cancer cell lines were significantly higher than that normal human colonic myofibroblasts cell line. Cell proliferation test results showed that cell proliferation was accelerated when MTAP was overexpression, cell invasion and migration were simultaneously accelerated. The expression of MTAP in primary liver was positively correlated with metastatic disease in patients with liver metastatic colorectal cancer via EMT.
CONCLUSIONS: MTAP accelerates the growth and metastasis of colorectal cancer through EMT.
