Imiquimod activates p53-dependent apoptosis in a human basal cell carcinoma cell line

Highlights • IMQ induces p53 expression and activation in skin cancer cells in a TLR7/8-independent manner. • The IMQ-induced p53 expression and activation are achieved through increased ROS production to stimulate the ATM/ATR-Chk1/Chk2 axis. • Genetic silencing of p53 significantly decreases the IM...
