Relationship between TH status and expression of TH transporters in the myocardium. Values are means (SD). A–C, MCTs (A); large neutral amino acid transporters (LAT; A);, 4F2 cell surface antigen heavy chain (LAT escort protein; 4F2hc) (B); fatty acid translocase (FAT; B); SLCO (C). All transporters from the SLCO transporter family had low cardiac gene expression levels (Ct values > 30) (n = 5–6/group). *, P < .05 vs control; †, P < .05 vs PTU; €, P < .05 vs PTU + 0.03 T3.
