Abstract

MicroRNAs (miRNAs) are dysregulated in human ovarian carcinoma (OC). But the mechanism underlying miR-10a-5p in regulating the progression of OC need deeply explored. In the current study, we observed that miR-10a-5p was down-expressed in OC samples and OC cell lines. In addition, miR-10a-5p restrained the viability, colony formation, migration ability and invasiveness of OC cells. We further ascertained Homeobox A1 (HOXA1) was a downstream gene of miR-10a-5p. Furthermore, HOXA1 was distinctly upregulated in OC samples. Finally, upregulation of HOXA1 abolished the suppressive effects of miR-10a-5p on OC cells. These observations suggested that miR-10a-5p suppressed the aggressive phenotypes of OC cells via regulating HOXA1.

Keywords: HOXA1; invasion; miR-10a-5p; migration; ovarian cancer.
