微小RNA与胃癌

MicroRNA and Gastric Cancer

胃癌的发生是基因和环境共同作用的结果。微小RNA(miRNA)分子可以调控细胞的增殖、分化和凋亡等过程,并对胃癌的发生、发展发挥重要的调节作用。近年来,miRNA与胃癌的相关性研究不断深入,从miRNA表达谱研究、miRNA与表观遗传相互调控及幽门螺杆菌感染相关miRNA等方面揭示了miRNA在胃癌发生发展中的作用。miRNA在血液中有高稳定性,循环miRNA无创诊断胃癌有着广阔的临床应用前景。

Gastric cancer is caused by the interaction of genetic and environmental factors. MicroRNA （miRNA） is involved in many cellular processes including proliferation, differentiation, and apoptosis and plays an important role in pathogenesis of gastric cancer, as demonstrated in many recent studies from perspec- tives including miRNA profiling, reciprocal modulation between epigenetic and miRNA, and Helicobacter pylori infection. MiRNA is highly stabe in blood, and therefore non-invasive diagnosis of gastric cancer using circulat- ing miRNA may be promising.
