MiR-4268 suppresses gastric cancer genesis through inhibiting keratin 80.

ABSTRACT: Gastric cancer (GC) affects a large proportion of cancer patients worldwide, and the prediction of potential biomarkers can greatly improve its diagnosis and treatment. Here, miR-4268 and keratin 80 (KRT80) expression in GC tissues and cell lines was determined. The effect of downregulating miR-4268 and interfering with KRT80 expression on the viability, proliferation, apoptosis, and migration of GC cells were evaluated. The interaction between miR-4268 and KRT80 was studied using luciferase reporter and RNA pull-down assays. The western blot, CCK-8, BrdU, caspase-3 activity, Transwell assays were performed for the functional characterization. In GC tissues and cells, KRT80 expression was found to be significantly higher, while that of miR-4268 was significantly lower than the respective e
