Abstract

The aberrant expression of microRNA‑183 (miRNA/miR‑183) has been found to be involved in numerous tumor types. However, the role of miR‑183 in gastric cancer pathology is unclear and requires investigation. In the present study, the miR‑183 expression levels of gastric cancer cell lines and tissues obtained from gastric cancer patients were measured by reverse transcription quantitative polymerase chain reaction analysis. The effect of miR‑183 on gastric cancer cell proliferation and invasion was evaluated using MTT, colony formation and Transwell assays. The target of miR‑183 was identified and confirmed using a luciferase activity assay. The results revealed that miR‑183 was significantly downregulated in gastric cancer cells compared with GES‑1 normal gastric epithelial cells. In addition, miR‑183 was reduced in gastric cancer tissues compared with adjacent normal tissues. The ectopic expression of miR‑183 significantly inhibited gastric cancer cell proliferation, colony formation and invasion. Bmi‑1 was also confirmed as a downstream target of miR‑183 in the gastric cancer cells by western blot analysis and luciferase activity assays. In conclusion, miR‑183 is downregulated in gastric cancer cells and tissues, and inhibits gastric cancer cell proliferation and invasion by targeting Bmi‑1. Therefore, targeting miR‑183 may be a potential therapeutic strategy in gastric cancer patients.
