The proliferative and migration abilities of colon cancer cells were determined with CCK-8 and Transwell cell assays, respectively.Results: Compared with untreated group, CNRIP1 promoter methylation level was decreased significantly in SW620 cells treated with 5-azaC, mRNA and protein expressions of CNRIP1 were increased significantly, mRNA and protein expressions of HK2, PKM2 and LDH-A were depressed significantly, and the proliferative and migration abilities were depressed significantly(P<0.05).Conclusion: CNRIP1 promoter demethylation could depress the glycolysis pathway, and reduce the proliferative and migration abilities in colon cancer cells %K 结肠癌 %K 大麻素受体互作蛋白1 %K 去甲基化 %K 糖酵解 %K 增殖 %K 迁移< %K br> %K colon cancer %K cannabinoid receptor interacting protein 1 %K demethylation %K glycolysis %K proliferation %K migration %U http://jms.zzu.edu.cn/oa/darticle.aspx?type=view&id=201801018
