Silencing of COPB2 inhibits the proliferation of gastric cancer cells and induces apoptosis via suppression of the RTK signaling pathway.

ABSTRACT: Emerging studies have reported that coatomer protein complex subunit β2 (COPB2) is overexpressed in several types of malignant tumor; however, to the best of our knowledge, no studies regarding COPB2 in gastric cancer have been published thus far. Therefore, the present study aimed to determine the significance and function of COPB2 in gastric cancer. COPB2 expression in gastric cancer cell lines was measured using reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) analysis. In addition, lentivirus‑short hairpin RNA (shRNA) COPB2 (Lv‑shCOPB2) was generated and used to infect BGC‑823 cells to analyze the effects of COPB2 on the cancerous phenotype. The effects of shRNA‑mediated COPB2 knockdown on cell proliferation were detected using MTT, 5‑bromo‑2‑deoxyuridine and colo
