Aldosterone upregulates Ca(2+) current in adult rat cardiomyocytes.

abstract：:Generation of proapoptotic sphingolipids by neutral sphingomyelinase activation is an early response to hypoxia/reoxygenation (HR) in cardiomyocytes. Factor associated with neutral sphingomyelinase activation (FAN) mediates activation of sphingomyelinase and subsequent apoptosis. However, the participation of FAN in H...
