Recent evidence shows that miRNAs are dysregulated in a variety of cancers
including gastric cancer (GC), and emerging as key oncogenes or tumor
suppressors. In this study, qRT-PCR was used to analyze the expression of miR-186
in GC tissues and adjacent non-cancerous tissues, and then more in-vitro
experiments were used to investigate the role of miR-186 in GC cells. Here, we
identified miR-186 was generally down-regulated in GC tissues; however, Twist1
was generally up-regulated in GC tissues. Moreover, miR-186 and Twist1 were
associated with larger tumor size and advanced clinical stage of GC. In-vitro
experiments demonstrated that ectopic overexpression of miR-186 inhibited GC cell
proliferation, invasion and migration; however, inhibited expression of miR-186
enhanced cell proliferation, invasion and migration. Furthermore, the luciferase
reporter assay demonstrated Twist1 as a direct target of miR-186. Finally,
over-expression of Twist1 abrogated inhibitory impact of miR-186 on cell
proliferation, invasion and migration. In conclusion, miR-186 affects the
proliferation, invasion and migration of human gastric cancer by inhibition of
Twist1, and could be a tumor suppressor in GC development. Thus, miR-186 may be
served as a candidate prognostic biomarker and target for new therapies in human
gastric cancer.
