  • Abstract:Background:miR-199a-3p was significantly downregulated in the majority of human hepatocellular carcinoma (HCC) tissues and HCC cell lines. Yes associated protein 1 (YAP1) was overexpressed in human HCC, which promoted HCC development and progression by upregulating Jagged1 and activating the Notch pathway. We searched potential targets of miR-199a-3p with DIANA, TargetScan and PicTar tools, and found that YAP1 is one of the potential targets. Based on these findings, we speculated that miR-199a-3p might suppress HCC growth by targeting YAP1, downregulating Jagged1 and suppressing the Notch pathway. Results:We determined the expression of miR-199a-3p and YAP1 by quantitative Real-Time PCR (qRT-PCR) and western blot assays, respectively, and found downregulation of miR-199a-3p and upregulation of YAP1 in HCC cell lines. Cell proliferation and apoptosis assays showed that miR-199a-3p suppresses HCC cell proliferation and promotes apoptosis, and knockdown of YAP1 has similar role. Furthermore, we verified that miR-199a-3p can directly target YAP1. We further investigated and confirmed that miR-199a-3p and YAP1 regulate HCC cell proliferation and apoptosis through Jagged1-Notch signaling. Conclusion:miR-199a-3p targets YAP1, downregulates Jagged1 and suppresses the Notch signaling to inhibit HCC cell proliferation and promote apoptosis. These findings provide new insights into the mechanism by which miR-199a-3p suppresses HCC cell proliferation and induces apoptosis.
