OBJECTIVE: The aim of this study was to evaluate the effectiveness of ranolazine on hypoxia-inducible factor-1α (HIF-1α) and oxidative stress in H9c2 cardiomyocyte cells. MATERIALS AND METHODS: We have assessed the effects of increasing concentrations of methotrexate (MTX) and ranolazine on proliferation of H9c2 rat cardiomyocyte cells by MTT assay. Malondialdehyde (MDA) protein oxidation [advanced oxidation protein products (AOPPs)], lipid hydroperoxide (LOOH) and xanthine oxidase (XO) activity as oxidative stress markers and HIF-1α levels increased and total thiol (T-SH), catalase (CAT) activity and total antioxidant capacity (TAC) antioxidant capacity markers decreased in MTX-treated cells compared to control cells. RESULTS: Oxidative stress markers decreased, and antioxidant capacity markers increased in cells treated with ranolazine alone compared to control cells. For all parameters, we showed that the levels of oxidant, antioxidant markers and HIF-1α in cells treated with MTX and ranolazine together reached the level of the control group, and ranolazine reversed the oxidative damage caused by MTX. CONCLUSIONS: The cell viability increased the levels of oxidant and prooxidant markers and decreased the levels of antioxidant markers decreased in H9c2 cardiomyocytes induced by oxidative stress. These results suggest that ranolazine may protect the cardiomyocytes from MTX-induced oxidative damage. The effects of ranolazine could result from its antioxidant properties.
