Figure 1. Nifedipine incubation reduces [Ca²⁺]_r in mdx myotubes.

Myotubes were incubated with 10 µM Nifedipine for 10 min at room temperature in Krebs Ringer solution and [Ca²⁺]_r was measured using double-barreled Ca²⁺ selective microelectrodes. Data are expressed as mean ± S.E.M. Wt (n = 10), mdx (n = 27), Wt+Nife (n = 10) and mdx+Nife (n = 10). ***P<0.001, ANOVA-Tukey’s.
