A IB analysis of the indicated proteins in control shRNA or YAP1-depleted SW 1353 cells. Cry61 was used as a positive control for the inactivation of YAP1 signaling. B A total of 154 miRNAs were found to be up- or downregulated in YAP1-depleted SW 1353 cells by high-throughput small RNA sequencing. C Eleven p21-regulating miRNAs were identified in YAP1-depleted SW 1353 cells by overlapping the above sequencing data with the predicted p21-targeting miRNAs with the online tools miRDB, miRTarBase, TargetScan, and DIANA-microT. D Heat map of 11 miRNAs regulated by YAP1 in SW 1353 cells. E The consensus sequences targeting p21 in the miR-17 family members were aligned. F qRT-PCR was used to quantify the expression of miR-17, miR-20a, miR-20b, miR-93, miR-106a, and miR-106b in the indicated cells. GI Control shRNA or YAP1-depleted SW 1353 cells were transfected with either miR-93 Control or miR-93 Mimic, and expression of p21 and p27 was analyzed by IB (G). The percentage of SA-β-gal-positive cells was quantified (H), and representative photos of the senescent cells are shown in (I), scale bars: 20 μm. J Control shRNA or YAP1-depleted SW 1353 cells were transfected with either miR-93 Control or miR-93 Inhibitor, and expression of the indicated protein was detected by IB. Data are presented as the mean ± SD of at least three independent experiments in (F, H). Student’s t-test for (F). Two-way ANOVA followed by Tukey’s test for (H). n.s. nonsignificant, **P < 0.01, ***P < 0.001, ****P < 0.0001.
