HSS promotes SERCA expression at MAM. Cells were treated with PA (300 μM) for 24 h. (a) Levels of SERCA were determined with western blotting. Densitometry results are shown. (b) SERCA activity was analyzed. (c) SERCA expression was measured in the ER and MAM compartments. Densitometry results are shown. *P<0.05.
