Arsenic Trioxide 0-16 tumor protein p53 Homo sapiens 72-75 25116336-4 2014 Previously, we found that arsenic trioxide (ATO), a drug for acute promyelocytic leukemia, degrades mutant p53 protein through a proteasome pathway. Arsenic Trioxide 26-42 tumor protein p53 Homo sapiens 107-110 25116336-4 2014 Previously, we found that arsenic trioxide (ATO), a drug for acute promyelocytic leukemia, degrades mutant p53 protein through a proteasome pathway. Arsenic Trioxide 44-47 tumor protein p53 Homo sapiens 107-110 25116336-8 2014 We also found that knockdown of Pirh2 inhibits, whereas ectopic expression of Pirh2 enhances, ATO-induced degradation of mutant p53 protein. Arsenic Trioxide 94-97 tumor protein p53 Homo sapiens 128-131 25116336-10 2014 Interestingly, we found that ATO cooperates with HSP90 or HDAC inhibitor to promote mutant p53 degradation and growth suppression in tumor cells. Arsenic Trioxide 29-32 tumor protein p53 Homo sapiens 91-94 25116336-11 2014 Together, these data suggest that ATO promotes mutant p53 degradation in part via induction of the Pirh2-dependent proteasome pathway.
