A–C, representative Western blots are shown for LAT1 (A), LAT2 (B) (30 kDa and 50 kDa) and CD98 (C) in TPM isolated from mice placenta at E18.5. D, bar graph summarizing the Western blot data from control (C, n= 6) and fADN (A, n= 6) infused groups. After normalization to β-actin, the mean density of control samples was assigned an arbitrary value of 1. Individual C and A density values were expressed relative to this mean. Values are given as means + SEM. *P < 0.05 versus control; Student's unpaired t test.
