Elevated expression of Yes-associated protein (YAP1) is associated with ovarian cancer. Bioinformatics analysis showed a relationship between miR-194 and YAP1. Our study intends to assess whether miR-194 regulates YAP1 expression and affects the proliferation of ovarian cancer cells
and CDDP resistance. CDDP-resistant cell line A2780/CDDP was established and the expression of miR-194 and YAP1 in parental A2780 cells and normal ovarian epithelial IOSE80 cells were compared. A2780/CDDP cells were separated into miR-NC group and miR-194 mimic group followed by analysis of
miR-194 and YAP1 expression, and cell apoptosis and proliferation by flow cytometry. There was a targeted relationship between miR-194 and YAP1 mRNA. A2780/CDDP cells had the lowest miR-194 expression followed by A2780 cells and IOSE80 cells. In addition, YAP1 level was highest in A2780/CDDP
cells followed by A2780 cells and IOSE80 cells. Compared with miR-NC group, miR-194 expression was significantly increased in miR-194 mimic transfection group and YAP1 protein expression was significantly decreased, with increased cell apoptosis and reduced cell proliferation ability. Decreased
miR-194 expression and increased YAP1 expression are related to ovarian cancer CDDP resistance. Increased miR-194 can down-regulate YAP1, inhibit ovarian cancer cell proliferation, promote cell apoptosis, and reduce CDDP resistance.
