Abstract

This work aims to elucidate the effects and the potential underlying mechanisms of microRNA-216a-3p (miR- 216a-3p) on the proliferation, migration, and invasion of gastric cancer (GC) cells. In this study, we revealed that the expression of miR-216a-3p was significantly elevated in GC tissues and cell lines. The different expression level of miR-216a-3p was firmly correlated with clinicopathological characteristics of GC patients. We next demonstrated that upregulation of miR-216a-3p could dramatically promote the ability of proliferation, migration, and invasion of GC cells using a series of experiments, whereas downregulation essentially inhibited these properties. Additionally, through bioinformatics analysis and biological approaches, we confirmed that runt-related transcription factor 1 (RUNX1) was a direct target of miR-216a-3p, and overexpression of RUNX1 could reverse the potential effect of miR-216a-3p on GC cells. Furthermore, mechanistic investigation using Western blot analysis showed that downregulation of RUNX1 by miR-216a-3p could stimulate the activation of NF-kB signaling pathway. In summary, this work proved that miR-216a-3p can promote GC cell proliferation, migration, and invasion via targeting RUNX1 and activating the NF-kB signaling pathway. Therefore, miR-216a-3p/RUNX1 could be a possible molecular target for innovative therapeutic agents against GC.
