MiR-134-3p driven by anisomycin impairs ovarian cancer stem cell activity through inhibiting GPR137 expression.

ABSTRACT: Background: Ovarian cancer recurrence and metastasis are predominantly attributed to ovarian cancer stem cells; however, the mechanism by which anisomycin regulates human ovarian cancer stem cells (HuOCSCs) remains unclear. Methods: cDNA microArray was used to screen microRNAs (miRNAs) targeted by anisomycin, and RT-qPCR validated the miRNA targets. TargetScan database, GO enrichment analysis, and RT-qPCR, accompanied by a fluorescent reporter system, were employed to verify the miRNA target genes. In vitro experimental cell proliferation inhibition assay, flow cytometry, Transwell, angiogenesis assay, and in vivo transplantation tumor assay were implemented to assess the ability of the overexpressed miRNAs to hinder HuOCSC activity. Western blot, RT-qPCR, and i
