Figure 4. YAP1/WWTR1 knockout impairs proliferation and induces apoptosis in dependent cells.
(A) Knocking out YAP1 or WWTR1 significantly inhibited cell proliferation in the respective dependent cell lines. Cell viability of HSC-2 (a YAP1- and WWTR1-non-dependent cell line) was not affected by depletion of either YAP1 or WWTR1. Experiments are repeated twice in technical triplicates. (n = 3 technical repeats for two biological repeats). Data shown as mean ± SD. *p<0.01; **p<0.001. (B) Apoptosis assay revealed that YAP1 depletion in YAP1-dependent ORL-48 resulted in significant increase in apoptotic cells while WWTR1 depletion in WWTR1-dependent ORL-214 resulted in an increase in apoptotic cells. No significant changes in apoptotic cells were observed in HSC-2 when either YAP1 or WWTR1 was depleted. Experiments are repeated twice in technical triplicates. Data of one experiment are shown as mean ± SD (n = 3 technical repeats). *p<0.01; **p<0.001.
