Estimates of whole body and muscle proteolysis in control and HIV-1 Tg rats. A and B: whole body proteolysis estimated from excretion of 3-methylhistidine (3-MH) in a 24-h urine sample normalized to LBM or urinary creatinine (Cr) concentration. Values are means ± SE of 12 PF control (PF Cont) and 14 HIV Tg rats. *P < 0.05 vs. PF Cont. C and D: in vitro-determined 26S and 20S proteasome activity of muscle (gastrocnemius) from ad libitum- and pair-fed control and HIV-1 Tg rats. Values are means ± SE of 6 AL, 12 PF, and 14 HIV-1 Tg rats. Means without a common letter (a, b) are significantly different (P < 0.05). E: representative Western blot showing increased abundance of 14-kDa actin fragment in gastrocnemius from HIV-1 Tg vs. control (AL and PF) rats.
