A. mRNA for proteasome subunit C2 in gastrocnemius muscle measured by semiquantitative RT-PCR with normalization to β-actin. Data are means ± SE. Compared to control group, *P < 0.05. B. Proteasome subunit C2 protein by western blot with protein levels quantified by densitometry and normalized to β-actin. Compared to control group, *P < 0.05; to LPS group, #P < 0.05; to low-dose insulin group, $P < 0.05.
