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

Figure 1

Uptake of the iodothyronine L-T₃ into 3T3-L1 adipocytes and pre-adipocytes. [¹²⁵I]-T₃ uptake was measured at 50 nM over 10 minutes in the absence (control) or presence of 10 $\mu$M unlabelled T₃ or 10 mM leucine in the uptake buffer. Values are expressed ± SEM of 6–12 measurements. *$P<.05$; value significantly different from control using Dunnett’s Multiple Comparison Test.
