Ticagrelor reduces doxorubicin-induced pyroptosis of rat cardiomyocytes by targeting GSK-3β/caspase-1.

ABSTRACT: Doxorubicin (Dox) is a widely used clinical drug whose cardiotoxicity cannot be ignored. Pyroptosis (inflammatory cell death) has gradually gained attention in the context of Dox-induced cardiotoxicity. In addition to the inhibition of platelet activation by ticagrelor, little is known about its other pharmacological effects. Glycogen synthase kinase 3β (GSK-3β) has been shown to contribute to the pathological process of pyroptosis, but whether it is related to the potential role of ticagrelor is unclear. In this study, we investigated the effects of ticagrelor on Dox-induced pyroptosis in cardiomyocytes. Rats were treated with ticagrelor (7.5 mg/kg, i.g.) 1 h before intravenous injection of Dox (2.5 mg/kg), once every 3 days, six times in total. Hearts were collected for histochemical ana
