Figure 5From: Transgenic overexpression of γ-cytoplasmic actin protects against eccentric contraction-induced force loss in mdx miceRemoval of extracellular calcium or addition of streptomycin does not affect immediate force loss during eccentric muscle contractions in mdx mice. (A) Eccentric contractions performed in calcium-free buffer (CaCl2 replaced with MgCl2). (B) Eccentric contractions performed in calcium-free buffer with the addition of 1 mM ethylene glycol tetraacetic acid (EGTA). (C) Eccentric contractions performed in normal buffer with the addition of 2 mM streptomycin. Data are means ± SEM. *Statistically significant difference from Krebs-Ringer bicarbonate buffer.Back to article page
