Protein synthesis (A nmol Phe/mg protein/3 h) and protein degradation (B; %) in IPEC-1 cells treated with or without 20 ng/ml LPS. Cells were cultured for 96 h in Arg-free DMEM containing 10, 100, or 350 μM arginine and 0 or 20 ng/ml LPS. Data are expressed as means ± SEM, n = 8. a–d Means sharing different letters differ (P < 0.001)
