MVM system A activity and SNAT 2 expression in relation to BMI and birth weight. A, Relationship between birth weight and system A amino acid transport activity was measured in vitro in MVM isolated from placentas of pregnancies with varying BMI and birth weights (n = 23). B, Representative Western blots for MVM expression of SNAT1, -2, and -4 isoforms of the system A amino acid transporter. C and D, Relationship between BMI (C) or birth weight (D) and MVM SNAT 2 expression. n = 22; r = Pearson's correlation coefficient.
