A Transfection efficacy of two siRNAs for YAP1 (siYAP1 No.1 and No.2). B Cisplatin sensitivity of siYAP1-transfected ES-2 cells measured using MTS assay. The viability of treated cells was compared with that of cells transfected with negative control siRNA (siCtrl) using Student’s t test. C Apoptosis assay of transfected cells treated with 7.5 µM cisplatin. The percentage of apoptotic cells was compared using Student’s t test. D Cisplatin sensitivity of YAP1 inhibitor-treated ES-2 cells measured using MTS assay. The viability of treated cells was compared with that of cells treated with DMSO using Student’s t test. E Expression of miRNAs and YAP1 in YAP1 overexpressed ES-2 cells (FLAG-YAP1) and mock transfected cells (FLAG). The cells were further transfected with combination of miR-509-3p and miR-509-3-5p. F Cisplatin sensitivity of FLAG-YAP1 cells measured using MTS assay. The viability of the two miRNAs transfected cells was compared with that of NC transfected cells using Student’s t test. G Representative images and bar graph of clonogenic assay. The transfected cells were treated with 1 µM cisplatin for 8 days, and the number of colonies was compare using Student’s t test. H The expression of phospho-YAP (Ser127) in the cytoplasm and nucleus of FLAG-YAP1 cells. Error bars represent standard errors of the mean. *p < 0.05, **p < 0.01, and ***p < 0.001.
