Abstract

Gastric cancer (GC) is a global health problem with poor clinical outcomes. The mechanism of its development and progression remains largely unclear. The present study investigated the role of microRNA‑9 (miR‑9‑5p) in the development and progression of GC. Overexpression of miR‑9‑5p led to reduced expression of neuropilin‑1 (NRP‑1) in GC cells. Dual‑luciferase reporter assay results indicated that miR‑9‑5p directly targeted NRP‑1. Furthermore, overexpression of miR‑9‑5p in GC cells increased the expression of mesenchymal markers, N‑cadherin and vimentin, and decreased the expression of epithelial markers, E‑cadherin and β‑catenin. Overexpression of miR‑9‑5p inhibited GC cell proliferation, migration and invasion, and increased the sensitivity of GC cells to the anti‑cancer drug cisplatin. By contrast, the opposite effects were observed in GC cells following downregulation of miR‑9‑5p. Taken together, the present findings suggested that miR‑9‑5p suppressed NRP‑1 expression and inhibited GC cell proliferation and invasion. In addition, miR‑9‑5p overexpression attenuated GC cell resistance to anti‑cancer drugs, which highlighted the potential of miR‑9‑5p as a target for the treatment of GC.
