Increased citrate synthase activity in gastrocnemius muscle from EX mice.

Gastrocnemius muscle was homogenized as described in the methods section. Citrate synthase activity in muscle homogenate was determined by measuring the production of SH-CoA from the condensation of dicarboxylate oxaloacetate and acetyl CoA by citrate synthase (n = 8 per group). The data are expressed as μmol/min/mg protein. *p < 0.001 compared to SED mice.
