Uterine uptakes of essential (EAA) and nonessential (NEAA) assessed by 3H20 transplacental diffusion at 130 dGA: (a) uterine uptakes of essential amino acids, μmol/min (b) uterine uptakes of essential amino acids, μmol/min. Data are shown as means ± SEM for all pregnancies in each treatment group. CSH, chorionic somatomammotropin; RNAi, RNA interference. Ala, alanine; Arg, arginine; Asn, asparagine; Cit, citrulline; Gln, glutamine; His, histidine; Ile, isoleucine; Leu, leucine; Lys, lysine; Met, methionine; Orn, ornithine; Phe, phenylalanine; Ser, serine; Thr, threonine; Tyr, tyrosine; Val, valine. ** p ≤ 0.01, * p ≤ 0.05, # p ≤ 0.10, when CSH RNAi pregnancies are compared with control RNAi pregnancies.
