OBJECTIVE: Our goal was to determine if the MKK6-p38 MAPK pathway regulates cardiac intracellular calcium ([Ca(2+)](i)). We also tested if MKK6 might influence expression of SERCA2, a calcium regulatory molecule involved in relaxation, and the …
In the present study, it was shown that physiologically relevant levels of the proinflammatory cytokine TNFalpha induced apoptosis in rat cardiomyocytes in vitro, as quantified by single cell microgel electrophoresis of nuclei (\"cardiac comets\") as …
To characterize the effects of the cellular events associated with contraction on atrial natriuretic factor (ANF) secretion, primary neonatal rat atrial myocytes were electrically paced to contract while being monitored for ANF release, cytoplasmic …
