Biliary injury improves in ATP binding cassette subfamily B member 4 (Abcb4−/−; Mdr2−/−) knockout (KO) mice at 2 and 4 weeks after Sobetirome (GC-1), at the expense of hepatic injury. Blood serum levels of alkaline phosphatase (ALP) show decreased biliary injury, whereas alanine aminotransferase (ALT) and aspartate aminotransferase (AST) indicate increased hepatic injury, in KO mice on short-term GC-1 diet compared with KO mice.

GC-1 treatment of hMet-mutant-β-catenin mice for 21-days leads to marked inhibition of Met signaling. A. A profound decrease in p-Met (Y1234/Y1235) is observed by WB analysis using whole liver lysates from GC-1 treated mice versus basal diet controls. A marginal but variable decrease in total Met was also evident in this group. GAPDH shows comparable loading. B. Another representative WB shows lack of p-Met (Y1234/1235) along with a dramatic decrease in downstream p-ERK1 (T202) and p-ERK2 (Y204)

Western blot of whole-liver lysates shows increased cyclin D1 and pSer675-β-catenin in GC-1-treated mice compared with DMSO control. Western blot analysis using whole-cell lysates from the livers from the two groups shows increased pSer675-β-catenin and cyclin D1 levels in the GC-1-treated group, while total β-catenin levels do not show much difference.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (7.61 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Protocol
Mice[2]
One hundred eighteen male C57BL/6 mice, 3 months old, are kept in standardized conditions with free access to water and normal chow. 3,5,3′-triiodo-L-thyronine (T3) or Sobetirome is administered i.p. in 20% DMSO or propylene glycol for 8 days, once daily at 9:00 a.m.; controls receive vehicle. In one experiment, nine groups of six mice are treated with vehicle, or 5.4, 24, 48, and 97 nmol/kg per day of T3 or Sobetirome. The lowest dose of T3 induces euthyroidism in hypothyroid mice. In another experiment, one group of seven mice is given no additional supplementation; three groups of seven mice receive 10% corn oil and 2% cholesterol (cholesterol diet); and three groups of seven mice receive 10% corn oil, 2% cholesterol, and 0.5% cholic acid (cholic acid diet). For this experiment, mice are treated with vehicle or 97 nmol/kg per day Sobetirome or T3. Food is withdrawn 5 h before kill. Blood is drawn by cardiac puncture under light isoflurane anesthesia. Animals are killed by cervical dislocation. Livers are immediately frozen in liquid nitrogen. For analysis of bile acid excretion, three groups of five chow-fed mice are treated with vehicle, 48 nmol/kg per day of Sobetirome, or T3 for 5 days. Feces are collected group-wise 24 h before treatment and in the last 24 h of the experiment.
Rats[3]
Female Wistar rats are randomly divided into five groups (n=8 per group): (i) control, treated with saline; (ii) 10× T3, treated with 3 μg T3/100 g body weight (BW) per day, which is equivalent to ten times the physiological dose of T3; (iii) 20× T3, treated with double of the previous T3 dosage (6 μg T3/100 g body weight (BW) per day); (iv) 10× Sobetirome, treated with 1.5 μg Sobetirome/100 g BW per day and (v) 20× Sobetirome, treated with 3 μg Sobetirome/100 g BW per day. The latter two groups are treated with Sobetirome in equimolar doses of 10× T3 and 20× T3 respectively. The equimolar doses of Sobetirome are calculated from the molecular mass of T3 (mol mass=651) and Sobetirome (mol mass=328.4). T3 is dissolved in 40 mM NaOH, and Sobetirome is dissolved in DMSO to a concentration of 1 mg/mL; either T3 or Sobetirome are then diluted in saline and administered i.p. every day for 6 weeks. BW is measured thrice a week. Body length (nose to base of the tail) is determined at the end of the experimental period.
