1 H2O2 evokes injury of cardiomyocytes through upregulating HMGB1. Hydrogen Peroxide high mobility group box 1 Rattus norvegicus
2 This study aimed to investigate the role of high-mobility group box 1 protein (HMGB1) in cardiomyocytes undergoing H2O2 treatment. Hydrogen Peroxide high mobility group box 1 Rattus norvegicus
3 This study aimed to investigate the role of high-mobility group box 1 protein (HMGB1) in cardiomyocytes undergoing H2O2 treatment. Hydrogen Peroxide high mobility group box 1 Rattus norvegicus
4 RESULTS: H2O2-induced ROS significantly decreased cell viability, promoted the apoptosis of neonatal myocytes, and upregulated the expression of HMGB1 in a dose-dependent manner. Hydrogen Peroxide high mobility group box 1 Rattus norvegicus
5 However, NAC or HMGB1 neutralizing antibody suppressed the loss of cell viability and the rate of cell apoptosis induced by H2O2. Hydrogen Peroxide high mobility group box 1 Rattus norvegicus
6 CONCLUSION: The present study suggests that H2O2-induced ROS evoke injury to cardiomyocytes that may be associated with upregulating HMGB1. Hydrogen Peroxide high mobility group box 1 Rattus norvegicus
