Cell-Specific Transport and Thyroid Hormone Receptor Isoform Selectivity Account for Hepatocyte-Targeted Thyromimetic Action of MGL-3196
Thyroid hormones (THs) and TH receptor-beta (TRβ) reduce hepatic triglycerides, indicating a therapeutic potential for TH analogs in liver steatosis. To avoid adverse extrahepatic, especially TRα-mediated effects such as tachycardia and bone loss, TH analogs with combined TRβ and hepatocyte specificity are desired. MGL-3196 is a new TH analog that supposedly meets these criteria. Here, we characterize the thyromimetic potential of MGL-3196 in cell-based assays and address its cellular uptake requirements. We studied the contribution of liver-specific organic anion transporters (OATP)1B1 and 1B3 to MGL-3196 action. The TR isoform-specific efficacy of MGL-3196 compared with 3,5,3′-triiodothyronine (T3) was determined with luciferase assays and gene expression analysis in OATP1B1 and OATP1B3 and TRα- or TRβ-expressing cells and in primary murine hepatocytes (PMHs) from wild-type and TRβ knockout mice. We measured the oxygen consumption rate to compare the effects of MGL-3196 and T3 on mitochondrial respiration. We identified OATP1B1 as the primary transporter for MGL-3196. MGL-3196 had a high efficacy (90% that of T3) in activating TRβ, while the activation of TRα was only 25%. The treatment of PMHs with T3 and MGL-3196 at EC50 resulted in a similar induction of Dio1 and repression of Serpina7. In HEK293 cells stably expressing OATP1B1, MGL-3196 had comparable effects on mitochondrial respiration as T3. These data indicate that MGL-3196’s hepatic thyromimetic action, the basis for its therapeutic use, results from a combination of hepatocyte-specific transport by OATP1B1 and the selective activation of TRβ over TRα
Molecular Dynamic Simulation To Reveal the Mechanism Underlying MGL-3196 Resistance to Thyroxine Receptor Beta
Thyroxine receptor beta (TRβ) is a ligand-dependent
nuclear
receptor that participates in regulating multiple biological processes,
particularly playing an important role in lipid metabolism regulation.
TRβ is currently a popular therapeutic target for nonalcoholic
steatohepatitis (NASH), while no drugs have been approved to treat
this disease. MGL-3196 (Resmetirom) is the first TRβ agonist
that has succeeded in phase III clinical trials for the treatment
of NASH; therefore, studying its molecular mechanism of action is
of great significance. In this study, we employed molecular dynamic
simulation to investigate the interaction mode between MGL-3196 and
TRβ at the all-atom level. More importantly, by comparing the
binding patterns of MGL-3196 in several prevalent TRβ mutants,
it was identified that the mutations R243Q and H435R located, respectively,
around and within the ligand-binding pocket of TRβ cause TRβ
to be insensitive to MGL-3196. This indicates that patients with NASH
carrying these two mutations may exhibit resistance to the medication
of MGL-3196, thereby highlighting the potential impact of TRβ
mutations on TRβ-targeted treatment of NASH and beyond
