Figure 3. The effect of TSH on HNF-4α phosphorylation is dependent on TSHR.
(A) Total protein (500 μg) from Tshr(+/+) and Tshr(−/−) mouse liver extracts were purified by IP with the HNF-4α antibody and subjected to WB with the p-Ser antibody. Total lysates were analyzed by WB with antibody against HNF-4α as indicated. Normal mouse IgG was used as a negative control. (B) Protein levels of cytoplasmic (-P) and nuclear (-N) HNF-4α were detected in Tshr(+/+) and Tshr(−/−) 8-week old littermate mice. All panels above are representative of 3 independent experiments. All the gels were run under the same experimental conditions, and key data cropped blots are used here. The full-length gel images are available in the Supplementary Figures.
