Regulation of L-type Ca2+ channels in the heart: overview of recent advances.

abstract：:Experiments were designed to determine if cotton bract tannin, a component of cotton mill dust, would promote the phosphorylation of alveolar macrophage proteins in doses potentially achievable in vivo. Rabbit alveolar macrophages were loaded with 32PO4 and challenged with various doses of tannin for time periods rang...

abstract：:Modulation of Ca(2+) homoeostasis in cardiac myocytes plays a major role in beat-to-beat regulation of heart function. Previous studies suggest that sphingosine-1-phosphate (S1P), a biologically active sphingomyelin metabolite, regulates Ca(2+) handling in cardiac myocytes, but the underlying mechanism is unclear. In ...
