(A) Survival curves for HFD- ThrbPV/PVPten+/− mice treated with S3I-201 (5 mg/kg body weight, n=12) or vehicle (0.05% DMSO, n=12)) I.P. injection 3 times a week from 8 weeks of age until they had to be euthanized because of sickness. Data are presented by Kaplan-Meir methods and analyzed by log-rank test. The p values are indicated. (B) Thyroid weights of vehicle-treated or S3I-201-treated wild type (n=10–11) or ThrbPV/PVPten+/− mice (n=10–13). (C-I). Comparison between the two groups of representative microphotographs of immunohistochemistry (IHC) one using anti-Ki67 antibody on thyroid sections from wild type mice with/without S3I-201 (panels a, b, c and d) and one without the treatment with primary antibodies are shown in the corresponding panels (a and c). The thyroid sections from ThrbPV/PVPten+/− mice (e, f, g, and h) and the negative without the treatment with primary antibodies are shown in the corresponding panels (e and g). (C-II) The Ki67-positive cells were counted and the data expressed as percentage of Ki67-positive cells versus total cells. The data are expressed as mean ± SE (n=2 slides). The p values are shown.
