Fig. 2From: Sex differences in sympathetic innervation and browning of white adipose tissue of miceCL treatment induces expression of brown adipocyte markers in gWAT female specifically. a,b Immunoblot analysis of mitochondrial proteins involved in oxidative phosphorylation. Two-way ANOVA revealed significant main effects of sex in mitochondrial proteins (ATP5A: p = 0.013, UQCRC2: p = 0.034, NDUFB8: p = 0.004) and significant interaction of sex and treatment (NDUFB8: p = 0.0054). Significant differences between male and female were determined by post hoc pairwise comparison with Bonferroni correction (mean ± SEM; n = 6, *p < 0.05, **p < 0.01). c qPCR analysis of brown adipocyte markers and genes involved in mitochondrial FFA oxidation in gWAT of male and female mice treated with CL for 3 days and untreated control mice. Two-way ANOVA revealed significant main effects of sex in brown adipocyte markers (Ppargc1a: p = 0.042, Cox8b: p = 0.011, Dio2: p <0. 0001) and significant interaction of sex and treatment (Ppargc1a: p = 0.008, Cox8b: p = 0.013, Dio2: p = 0. 001). Significant differences between male and female were determined by post hoc pairwise comparison with Bonferroni correction (mean ± SEM; n = 4, **p < 0.01). d Mitochondrial respiration in gWAT of male and female mice treated with CL for 3 days (mean ± SEM; n = 4, *p < 0.05) as determined by reduction of the electron acceptor dye TTC. e–h VO2 (e), energy exchange ratio (RER) (f), and energy expenditure (EE) (g) are shown. h Total EE for 24 h (dark, 12 h; light, 12 h) without stimulation (h, left panel) and total EE for 12 h after CL injection (h, right panel). Arrows indicate the time of CL injection. Mean ± SEM, n = 6 per groupBack to article page
