Iodothyronine Interactions with the System L1 Amino Acid Exchanger in 3T3-L1 Adipocytes

Figure 2

Effect of amino acids and iodothyronines on uptake of phenylalanine into 3T3-L1 adipocytes. [³H]phenylalanine uptake was measured at 5 $\mu$M over 3 minutes in the absence (control) or presence of 10 $\mu$M iodothyronine or 10 mM amino acid in the uptake buffer. Values are expressed $\pm$ SEM of 3 measurements (except where indicated) as % of the control flux. **$P<.01$; value significantly different from control using Dunnett’s Multiple Comparison Test.
