Kaempferol attenuated cisplatin-induced cardiac injury via inhibiting STING/NF-κB-mediated inflammation.

Cardiovascular complications have been well documented as the downside to conventional cancer chemotherapy. As a notable side effect of cisplatin, cardiotoxicity represents a major obstacle to the successful treatment of cancer. It has been reported that kaempferol (KPF) possesses cardioprotective and anti-inflammatory qualities. However, the effect of KPF on cardiac damage caused by conventional cancer chemotherapy remains unclear. In this study, we clarified the protective effect of KPF on cisplatin-induced heart injury, and conducted in-depth research on the molecular mechanism underlying this effect. The results showed that KPF protected against cardiac dysfunction and injury induced by cisplatin in vivo. In H9c2 cells, KPF dramatically reduced cispaltin-induced apoptosis and inflammatory response by modulating STING/NF-κB pathway. In conclusion, these results showed that KPF had great potential in attenuating cisplatin-induced cardiac injury. Besides, greater emphasis should be placed in the future on natural active compounds containing KPF with anti-inflammatory effects for the treatment of these diseases.
