Female adult mouse cardiomyocytes are protected against oxidative stress.
Premenopausal women have less cardiovascular disease and lower cardiovascular morbidity and mortality than men the same age. Our previous studies showed that female mice have lower mortality and better preserved cardiac function after myocardial infarction. However, the precise cellular and molecular mechanisms responsible for such a sex difference are not well established. Using cultured adult...
متن کاملSperm of colourful males are better protected against oxidative stress.
Sperm cells are highly vulnerable to free radicals, and sperm quality and male fertility are critically affected by oxidative stress. Recently, sexual ornaments, particularly carotenoid-based colourful traits, have been proposed to depend on a male's capacity to resist oxidative stress, and thus to signal sperm quality. We conducted an experimental test of this hypothesis on great tits Parus ma...
متن کاملTitin isoforms in heart failure: are there benefits to supersizing?
Titin is a giant sarcomeric protein that functions as a complex, molecular spring. Its presence in the sarcomere of striated muscle was recognized in the 1980s,1 but its functions have been appreciated only over the past decade, in considerable measure because of the efforts of Granzier, Labeit, Linke, and coworkers.2–4 Earlier work by these investigators and others4 delineated the spring prope...
متن کاملProtective effect of pomegranate seed oil against H2O2 -induced oxidative stress in cardiomyocytes
Objective: It has been well documented that oxidative stress is involved in the pathogenesis of cardiac diseases. Previous studies have shown that pomegranate seed oil (PSO) has antioxidant properties. This study was designed to investigate probable protective effects of PSO against hydrogen peroxide (H2O2)-induced damage in H9c2 cardiomyocytes.Materials and Methods: The cells were pretreated 2...
متن کاملSIRT5: a safeguard against oxidative stress-induced apoptosis in cardiomyocytes.
BACKGROUND SIRT5 is located in the mitochondria, and plays a crucial role in the regulation of metabolic process and cellular apoptosis. Cardiomyocytes are abundant in mitochondria. However, the role of SIRT5 in oxidative stress-induced apoptosis is still unknown in cardiomyocytes. METHODS AND RESULTS Western blots analysis revealed that SIRT5 is significantly down-regulated in cardiomyocytes...
