ABSTRACT
BACKGROUND:
The aim of this research was to investigate the mechanism of miR-96 affecting hepatocellular carcinoma (HCC).METHODS:
mRNA and protein expression was detected by qRT-PCR and Western blot, respectively. HepG2 cells were transfected and grouped as follows miR-NC group, miR-mimics group, NC + Vector group, mimics + Vector group, mimics + FOXO1 group. Luciferase reporter assay was performed. MTT and Transwell assay was conducted. In vivo studies by nude mice were performed. Immunohistochemistry and immunofluorescence was executed.RESULTS:
Up-regulated miR-96 and down-regulated FOXO1 was found in tumor tissues and HepG2 cells (P < 0.01). FOXO1 was directly suppressed by miR-96. Compared with NC + Vector group, mimics + Vector group has higher OD495 value (P < 0.05), higher migration and invasion cells (P < 0.01), larger transplanted tumor volume (P < 0.01), lower FOXO1 positive cell numbers (P < 0.01), higher p-AKT and p-GSK-3ß expression (P < 0.01), lower p-ß-catenin expression (P < 0.01), more ß-catenin expression in the nucleus (P < 0.01). Compared with mimics + Vector group, mimics + FOXO1 group has lower OD495 value (P < 0.05), lower migration and invasion cells (P < 0.01), smaller transplanted tumor volume (P < 0.01), higher FOXO1 positive cells (P < 0.01), lower p-AKT and p-GSK-3ß expression (P < 0.01), higher p-ß-catenin expression (P < 0.01), less ß-catenin expression in the nucleus (P < 0.01).CONCLUSION:
miR-96 exerts carcinogenic effect by activating AKT/GSK-3ß/ß-catenin signaling pathway through targeting inhibition of FOXO1 in HCC.
