Depletion of CSE1L induces a more pronounced cytotoxicity in p53 WT NSCLC cells. A549 p53+/+ and p53−/− cells were transfected with control siRNA or CSE1L siRNA for 72 h and then analyzed with MTT assay (A) or FACS analysis for sub-G1 (B). Average (8 replicates) relative MTT absorbance and average (triplicate) % sub-G1 cells are presented with SD indicated. (C) A549 p53+/+ and p53−/− cells were transfected with control siRNA or CSE1L siRNA for 48 h and then plated for colony formation assay. Average (triplicate) % colony formation is presented with SD indicated. Representative images are presented. (D). A549 p53+/+ and p53−/− cells were treated with vehicle or onvansertib (1 µM) for 72 h and then analyzed for sub-G1 cells. % sub-G1 cells are presented with SD indicated. Statistical differences (* p < 0.05) are indicated in (A), (B), and (C). There is no significant difference in D.
