TFE3 regulates glucose homeostasis AGlucose levels in fed and after 24 h fasting in 2‐month‐old WT and Tfe3 KO mice (n = 12 per group). Data are presented as mean ± SEM. Student's two‐tailed t‐test: ***P < 0.001.B, CPlasma insulin (B) (n = 5 WT and n = 3 Tfe3 KO) and glucagon (C) (n = 12 per group) levels in WT and Tfe3 KO mice. Data are presented as mean ± SEM. Student's two‐tailed t‐test: **P = 0.0090; *P =  D–FInsulin and glucose tolerance tests in WT and Tfe3 KO mice fed a chow diet. Glucose levels (D) at the indicated time points after insulin challenge (n = 3 per group). Glucose (E) (n = 20 per group) and serum insulin (F) (n = 5 per group) levels at the indicated time points after glucose challenge. Data are presented as mean ± SEM. ANOVA test followed by post hoc Bonferroni test: GTT ***P =   min; *P =   min; ***P =   min; insulin during GTT ***P = 0.0005; *P =  GPyruvate tolerance test in WT (black line; n = 5) and Tfe3 KO mice (red line; n = 4) fed a chow diet. Data are presented as mean ± SEM. ANOVA test followed by post hoc Bonferroni test: **P =  HExpression analysis of genes involved in gluconeogenesis in the liver (n = 5 per group).

Data are presented as mean ± SEM. Student's two‐tailed t‐test: blood glucose *P = 0.049; blood lactate *P = 0.027.LExpression analysis of Gsk3 in muscle of WT and Tfe3 KO mice fed a chow diet (n = 4 per group).
