The Efficacy of Etoposide on H9c2 Cardiomyoblasts Against Doxorubicin Induced Cardiotoxicity
Author(s): Sara Shabana*
Background: Doxorubicin (DOX), a widely used anticancer drug, has been associated with cardiotoxicity. Recently, DOX-induced cardiotoxicity has been attributed to topoisomerase II (TOPII)-β expression and activity. In our study, we investigated the effect of inhibiting TOPII in attenuating the DOX induced cardiotoxicity.
Method: H9c2 cardiomyoblasts were treated with 1 or 2 μM DOX (+/-) 1 μM ETO. Cardiotoxicity was assessed by examining cell viability using the MTT assay, hypertrophy of crystal violet stained cardiomyoblasts and ROSproduction.
Results: DOX induced a dose dependent increase in cardiotoxicity as indicated by the significant reduction in cell viability (71.77 ± 9.25% 2 μM DOX vs. 100% control, P<0.05), ROS production and hypertrophy. Stimulation of H9c2 cardiomyoblasts with bot.. View More»
