Main methods
In this study, we used human renal cortical epithelial (HRCE) cells. The anti-apoptotic effect of βOHB was evaluated using flow cytometry analysis. The expression of apoptosis-related proteins and HDACs was evaluated by western immunoblot.
Key findings
The results showed that βOHB significantly reduced cisplatin-induced apoptosis in HRCE cells. Furthermore, βOHB significantly reduced cisplatin-induced cleavage of caspase-3, acetylation of histone H3, and phosphorylation of AMP-activated kinase. This anti-apoptotic effect of βOHB was markedly attenuated by an inhibitor of HDAC4/5, and βOHB-mediated suppression of cleavage of caspase3 was significantly blocked by siRNA-induced gene silencing of HDAC5.
Significance
βOHB attenuates cisplatin-induced apoptosis by activation of HDAC5 in HRCE cells, suggesting that βOHB may be a new therapeutic agent for cisplatin nephropathy.
