摘要: Hesperidin (HES), a citrus fruit extract, has beneficial effects on various ischemia/reperfusion (I/R) models. Here, we investigated the possible positive effect of hesperetin (HPT), an active metabolite HES, and identified potential molecular mechanisms involved in cardiomyocytes H/R-induced injury. To construct cardiomyocyte model hypoxia/reoxygenation (H/R) injury, cultured neonatal rat were subjected to 3h hypoxia followed by reoxygenation. Cell viability apoptosis detected. The levels Apoptosis-related proteins PI3K/Akt detected western blot. Our results showed that HPT post-treatment significantly inhibited elevating expression Bcl-2, decreasing Bax cleaved caspase-3, diminished apoptotic ratio. Mechanism studies demonstrated up-regulated p-PI3K, p-Akt. Co-treatment with PI3K/Akt-specific inhibitor LY294002 blocked HPT-induced cardioprotective effects. Taken together, these data suggested prevented from H/R injury vitro most likely through activation signaling pathway.
