Insulin resistance of lean or HFD-fed Gpnmb-/- and wildtype mice. (A) Blood glucose time line of oral glucose tolerance test conducted in 6 h fasted animals and (B) its respective integrated area under the curve (iAUC). (C–E) Blood glucose of (A) in comparison to female control animals. (F,I) ELISA of insulin and C-peptide in plasma. (J–K) Homeostatic model assessment for insulin resistance (HOMA-IR), a product of insulin and fasted blood sugar. NC: normal chow, HFD: high fat diet. n = 6–7, mean ± SEM. Statistical differences were determined by a non-parametric t-test/Mann Whitney test for female animals (C,F,H,J) and by a Two-way ANOVA with Bonferroni post-hoc tests for male animals (A,B,D,E,G,I,K). (A) * C57BL/6N (16 weeks HFD) vs. C57BL/6N-Gpnmb-/- (16 weeks HFD); $ C57BL/6N (16 weeks HFD) vs. C57BL/6N (NC); § C57BL/6N-Gpnmb-/- (16 weeks HFD) vs. C57BL/6N-Gpnmb-/- (NC). For all graphs: * p < 0.05; **/$$ p < 0.01; ***/§§§ p < 0.001.
