Effects of the level of nutrient intake on abundance of growth-related proteins in psoas major muscle of pigs with different birth weight. ANI, adequate nutrient intake; HNI, high nutrient intake; IUGR, intrauterine growth restriction; NBW, normal birth weight; mTOR, mammalian target of rapamycin; p-mTOR, phosphorylated mTOR; Akt, protein kinase B; P-Akt, phosphorylated Akt; RPS6, ribosomal protein S6; P-RPS6, phosphorylated RPS6; eIF4E, eukaryotic translation initiation factor 4E; P-eIF4E, phosphorylated eIF4E. Values are means, with their standard errors represented by vertical bars (n = 6 for each group). Mean values with different letters (a, b) were significantly different between four groups (P < 0.05). ^*P < 0.05 for the respective sources of variation (nutrition intake or body weight)
