Figure Lengend Snippet: Andrographolide prevents HFD-induced weight increase and adipogenic differentiation (A and B) Body weights of mice fed with HFD increased markedly. Intragastric administration of andrographolide reduced the increase significantly. AP does not change body weight of mice received normal diet, and did not affect the amounts of the food intake. (C) Histology of mice fed with HFD with or without given AP. Scale bars, 100 μm. (D) Weights of visceral, subcutaneous, and brown adipose tissues from HFD- and HFD plus andrographolide-fed mice.

Figure Lengend Snippet: Andrographolide acts on GSK3β (A) GSK3β was dephosphorylated at S9 upon inducing differentiation of ADSCs toward adipocytes. AP prevents the dephosphorylation of GSK3β dose-dependently. (B) In cellular thermal shift assay, AP protected GSK3β from denaturing and increases the amount of protein in the supernatants, indicative of direct binding. (C) Similar to AP, small molecular inhibitor of GSK3β laduviglusib also blocks the adipogenic differentiation of ADSCs as revealed by oil red O staining. Scale bars, 100 μm.
