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 …
While hormonal stimuli and mechanical stretch can induced cardiac-specific gene expression and in some cases cellular hypertrophy, the relationship between myocyte contraction frequency, gene expression, and myocyte growth has not been well …
