Antioxidants and Phase 2 Enzymes in Cardiomyocytes: Chemical Inducibility and Chemoprotection Against Oxidant and Simulated Ischemia-Reperfusion Injury

Abstract

The increasing recognition of the role for oxidative stress in cardiac disorders has led to extensive investigation on the protection by exogenous antioxidants against oxidative cardiac injury. On the other hand, another strategy for protecting against oxidative cardiac injury may be through upregulation of the endogenous antioxidants and phase 2 enzymes in the myocardium by chemical inducers. However, our current understanding of the chemical inducibility of cardiac cellular antioxidants and phase 2 enzymes is very limited. In this study, using rat cardiac H9c2 cells we have characterized the concentration- and time-dependent induction of cellular antioxidants and phase 2 enzymes by 3H-1,2-dithiole-3-thione (D3T), and the resultant chemoprotective effects on oxidative cardiac cell injury. Incubation of H9c2 cells with D3T resulted in a marked concentration- and time-dependent induction of a number of cellular antioxidants and phase 2 enzymes, including catalase, reduced glutathione (GSH), GSH peroxidase, glutathione reductase (GR), GSH S-transferase (GST), and NAD(P)H:quinone oxidoreductase-1 (NQO1). D3T treatment of H9c2 cells also caused an increase in mRNA expression of catalase, gamma-glutamylcysteine ligase catalytic subunit, GR, GSTA1, M1 and P1, and NQO1. Moreover, both mRNA and protein expression of Nrf2 were induced in D3T-treated cells. D3T pretreatment led to a marked protection against H9c2 cell injury elicited by various oxidants and simulated ischemia-reperfusion. D3T pretreatment also resulted in decreased intracellular accumulation of reactive oxygen in H9c2 cells after exposure to the oxidants as well as simulated ischemia-reperfusion. This study demonstrates that a series of endogenous antioxidants and phase 2 enzymes in H9c2 cells can be induced by D3T in a concentration- and time-dependent fashion, and that the D3T-upregulated cellular defenses are accompanied by a markedly increased resistance to oxidative cardiac cell 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.
