Curcumin derived from the rhizome of turmeric (Curcuma longa L.), is a well known coloring culinary agent, that has therapeutic properties against diverse pathologies such as cancer, atherosclerosis and heart failure. Given the salutary potential of curcumin, deciphering its mode of action particularly in cardiac cells, is of outstanding value. Accumulating(More)
One of the most significant insults that jeopardize cardiomyocyte homeostasis is a surge of reactive oxygen species (ROS) in the failing myocardium. Early growth response factor-1 (Egr-1) has been found to act as a transcriptional regulator in multiple biological processes known to exert deleterious effects on cardiomyocytes. We thus investigated the(More)
The aim of the present study was to examine and compare the role of the stress-activated protein kinases in ischemic and stretch-induced preconditioning. A model of anesthetized rabbits was used, and the preconditioning protocol included one or three cycles of short ischemia/reperfusion, or short mechanical stretch with acute pressure overload without or(More)
pH is one of the most important physiological parameters, with its changes affecting the function of vital organs like the heart. However, the effects of alkalosis on the regulation of cardiac myocyte function have not been extensively investigated. Therefore, we decided to study whether the mitogen-activated protein kinase (MAPK) signaling pathways [c-Jun(More)
Gender seems to interfere with the cardioprotective effect of ischemic preconditioning (PreC) and postconditioning (PostC); PreC-conferred protection is weaker or lost in female animals after ovariectomy (Ov), while the role of PostC is still in dispute. We sought to investigate the effect of PostC in female rabbits, its interaction with Ov, and the(More)
Atrial natriuretic peptide (ANP) is a cardiac hormone involved in the regulation of fluid balance and blood pressure homeostasis. Using conventional reverse transcription and polymerase chain reaction and amplification, preproANP transcript from Rana ridibunda heart ventricle was cloned and characterized. Sequence analysis of the complete cDNA revealed an(More)
