Abstract

Our previous studies showed that the effect of resveratrol preventing mitochondrial permeability transition pore (mPTP) opening in myocardial ischemia/reperfusion injury was achieved by regulating voltage-dependent anion channel 1 (VDAC1). However, the underlying mechanism remains unclear. Previous studies demonstrated that the activity and function of VDAC1 are highly regulated by post-translational modification. In present study, we investigated whether resveratrol modulates VDAC1 phosphorylation to achieve cardioprotection and explored the signaling pathways involved. Our findings demonstrated that anoxia/reoxygenation (A/R) treatment, an ischemia/reperfusion model in vitro, enhanced VDAC1 phosphorylation in cardiomyocytes. Moreover, we found phosphorylated VDAC1 showed increased affinity to Bax, whereas interaction with hexokinase 2 (HK2) was reduced. Accordingly, the generation of reactive oxygen species increased, the mitochondrial membrane potential collapsed, mPTP opening increased and cytochrome c released into cytoplasm, thereby leading to increased apoptosis. Moreover, our data showed that pretreatment with resveratrol prior to A/R injury inhibited VDAC1 phosphorylation. Dephosphorylated VDAC1 using pretreated resveratrol promoted dissociation with Bax and binding to HK2, which subsequently protected cardiomyocytes against A/R injury. In addition, Akt and its downstream glycogen synthase kinase 3 β (GSK3β) were phosphorylated by the action of resveratrol. Akt inhibitor IV abrogated Akt-GSK3β phosphorylation and thereby abolished the dephosphorylation activity of resveratrol on VDAC1. Moreover, all resveratrol-mediated protective effects on A/R injured cardiomyocytes were abolished by Akt inhibitor IV. Taken together, our data indicated that A/R injury enhanced VDAC1 phosphorylation in cardiomyocytes, whereas pretreatment with resveratrol dephosphorylated VDAC1 through the Akt-GSK3β pathway, thereby protecting cardiomyocytes against A/R injury.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
