Neuregulin-1 attenuated doxorubicin-induced decrease in cardiac troponins

Neuregulin-1 attenuated doxorubicin-induced decrease in cardiac troponins.

Neuregulin-1 (NRG1) is a potential therapeutic agent for the treatment of doxorubicin (Dox)-induced heart failure. NRG1, however, activates the erbB2 receptor, which is frequently overexpressed in breast cancers. It is, therefore, important to understand how NRG1, via erbB2, protects the heart against Dox cardiotoxicity. Here, we studied NRG1-erbB2 signaling in Dox-treated mice hearts and in is...

Protective role of neuregulin-1 toward doxorubicin-induced myocardial toxicity.

The aim of this study was to investigate the role of the rat neuregulin-1 (NRG-1) protein in reducing doxorubicin (DOX)-induced myocardial toxicity and its underlying mechanism. The prokaryotic expression of the NRG-1 protein and the CCK8-determined activity of rat primary myocardial cells were evaluated under different DOX concentrations. Myocardial cells were divided into three groups: the co...

Cardiac troponins.

Cardiac troponins

Objective: To review the use of cardiac troponins as biomarkers for myocardial injury in human and veterinary medicine. Data sources: Data sources included scientific reviews and original research publications. Human data synthesis: Cardiac troponins have been extensively studied in human medicine. Finding an elevated cardiac troponin level carries important diagnostic and prognostic informatio...

Prior exercise training attenuated Doxorubicin-induced hepatic oxidative stress in Wistar rats: Age-related differences

Introduction: Previous studies have confirmed the sidelong effects of Doxorubicin (DOX) on healthy tissues, but pretreatment effect of regular Aerobic exercise in restrain of hepatotoxicity induced by doxorubicin is not clear. The aim of this study was to investigate the pretreatment effect of regular aerobic exercise on hepatic oxidative stress induced with doxorubicin of Wistar rats in differ...
