Evaluation of the TP53-dependent mechanism of OR-2100. (A) RC and OCI-Ly18 cells were transduced with shRNA that targeted TP53, and the reduction in TP53 expression was confirmed by immunoblotting. (B) The cells were treated with OR-2100 for 72 hours, followed by assessment of the cell viability. (C) The protein expression levels of β-tubulin and borealin (CDCA8) in RC and OCI-Ly18 cells treated with OR-2100 was assessed by western blotting. The representative images demonstrate that the protein levels of borealin was more profoundly downregulated in shCtr cells than in shTP53 cells.
