FIGURE 7.
Expression of Ca2+-handling proteins in Wt and RyR-null primary myotubes. Left, representative Western blots using antibodies directed against RyR1, PMCA, NCX3, SERCA1, myosin (to demonstrate similar differentiation state), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) as a loading control. Right, expression of RyR1 associated with a significant decrease in the expression of SERCA and NCX3 and a significant up-regulation of the expression of PMCA. Data are expressed as mean ± S.D., n = 5 Western blots/group.
