Figure Legend Snippet: SHP2 deficiency in macrophages protects mice from HFD-induced obesity by promoting energy expenditure. WT and cSHP2-KO mice were fed on NCD or HFD. A to C, body weight change (A and B) and food intake (C) were recorded. **, p < 0.01 versus corresponding time point from WT-HFD. Energy expenditure of HFD-fed WT and cSHP2-KO mice were monitored using CLAMS for 24 h. D, the curve of oxygen consumption rate (VO2). E, the carbon dioxide production rate (VCO2). F, heat production. Data are expressed as mean ± S.E., n = 6–8. *, p < 0.05.
Techniques Used:
Figure Legend Snippet: Ablation of SHP2 in macrophages protects mice from HFD-induced insulin resistance. WT and cSHP2-KO mice were fed on NCD or HFD. A and B, glucose tolerance test and insulin tolerance test were performed on mice with 14 weeks of HFD feeding. C, hepatic gluconeogenesis was determined by PTT assay. *, p < 0.05; **, p < 0.01 versus corresponding time point from WT. D, Pepck and G6Pase mRNA level in liver was determined by qPCR. E, fasting insulin level in the serum was determined by ELISA. F, insulin signaling in liver was determined by Western blot analysis after 6 h of fasting. Data are expressed as mean ± S.E., n = 6–8. *, p < 0.05; ns, not significant.

Figure Legend Snippet: Loss of SHP2 in macrophages promotes elevated IL-18 secretion and caspase-1 activation both in vivo and in vitro. A and B, after feeding on NCD or HFD for 16 weeks, mice were sacrificed. The levels of IL-1β and IL-18 in the serum were determined by ELISA (A), and caspase-1 (CASP1) activation in peripheral macrophages from mice was determined by Western blotting (B). C–F, Peritoneal macrophages obtained from WT and cSHP2-KO mice were stimulated with 100 ng/ml LPS in the presence of ceramide (0.1 mm) or palmitic acid (PA, 200 μm). The level of IL-18 in the supernatant was determined by ELISA (C and E); CASP1 activation was determined by Western blotting (D and F). Data are expressed as mean ± S.E. in panels A–E, n = 6 in A and n = 3 in C, E. *, p < 0.05; **, p < 0.01.
Techniques Used: Activation Assay, In Vivo, In Vitro, Enzyme-linked Immunosorbent Assay, Western Blot
Figure Legend Snippet: SHP2 deficiency-caused increase of insulin sensitivity is almost blocked by caspase-1 deletion. WT, cSHP2-KO, and SHP2/caspase-1 double knockout (DKO) mice were fed on HFD for 16 weeks. A, body weight change was recorded. B and C, GTT and ITT assays were carried out after mice were on HFD for 14 weeks. D, fasting insulin level in the serum of mice was determined by ELISA. E, insulin signaling in liver was determined by Western blotting after 6 h fasting.

Figure Legend Snippet: The SHP2 inhibitor SHP099 improved hepatic steatosis and insulin resistance in HFD mice. C57BL/6 mice were fed on HFD for 16 weeks. After that, mice were i.p. treated with 2.5 and 5 mg/kg SHP099 for 16 days. A, change of body weight was recorded. B and C, GTT and ITT assays were performed. D and E, fasting level of insulin and IL-18 in serum was examined by ELISA. F and G, weight (F) and H&E staining (G) of liver from SHP099-treated and control mice. Scale bar, 50 μm.

Figure Legend Snippet: The graphic illustration for the mechanism of SHP2 regulating HFD-induced obesity and insulin resistance. Knockout of SHP2 in macrophage significantly ameliorates HFD-induced obesity and insulin resistance in mice through promoting caspase-1-dependent overproduction of IL-18. IL-18 promotes lipolysis in target tissues and alleviates the whole-body lipid accumulation as well as insulin resistance. More importantly, SHP2-specific inhibitor SHP099 and Phps1 significantly ameliorates HFD-induced insulin resistance and fat liver, indicating a potential drug target for treatment of insulin resistance.
