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.
微小 RNA(miRNAs)在人类卵巢癌(OC)中失调。但是,miR-10a-5p 调节 OC 进展的机制需要深入研究。在本研究中,我们观察到 miR-10a-5p 在 OC 样本和 OC 细胞系中表达下调。此外,miR-10a-5p 抑制 OC 细胞的活力、集落形成、迁移能力和侵袭能力。我们进一步确定同源盒 A1(HOXA1)是 miR-10a-5p 的下游基因。此外,HOXA1 在 OC 样本中明显上调。最后,HOXA1 的上调消除了 miR-10a-5p 对 OC 细胞的抑制作用。这些观察结果表明,miR-10a-5p 通过调节 HOXA1 抑制 OC 细胞的侵袭表型。
