Abstract

MicroRNAs (miRs) are involved in many aspects of cell biology, including cell proliferation and apoptosis, two critical aspects of tumor biology. We investigated the effect of miR‑711 on Bcl‑2 expression in human MGC803 gastric cancer cells and the mechanism of cell proliferation, apoptosis, and invasion. Expression of miR‑711 and Bcl‑2 was significantly increased in gastric adenocarcinoma compared to adjacent normal tissue. Inhibition of miR‑711 in MGC803 gastric cancer cells decreased the expression of Bcl‑2, decreased cell proliferation, decreased the invasion ability, and increased apoptosis. The expression of Bcl‑2 protein correlated with clinical staging, lymph node metastasis, and tumor differentiation in patients with gastric cancer. The expression of miR‑711 positively correlated with the expression of Bcl‑2, suggesting that miR‑711 and Bcl‑2 are co‑regulated and involved in the development of gastric cancer.
