AdipoRon administration suppresses ILC2 and energy expenditure in adiponectin KO mice. (A) The effect of AdipoRon administration (30 mg/kg i.p. once per day for 5 d) on basal and cold-induced O2 consumption in 10-wk-old adiponectin KO mice. 24 h after administration of AdipoRon, the calorimetry study was performed. The average O2 consumption was normalized to whole-body mass and analyzed by ANOVA. n = 7–9/group. Data are presented as means ± SEM. *, P < 0.05. (B and C) Expression levels of UCP1, C/EBPβ, and PGC1α were significantly down-regulated by AdipoRon administration in iWAT (B) without significant difference in BAT (C) in adiponectin KO mice. Representative data are presented. (D and E) Administration of AdipoRon decreased the fractions of ILC2s (D) and M2 macrophages (E) in iWAT in adiponectin KO mice despite no significance in eWAT. n = 4–6/group. Data are presented as means ± SEM. *, P < 0.05, Student’s t test. (F) Intra-iWAT injection of AdipoRon (3 mg/kg body mass) suppressed cold-induced expression of UCP1, C/EBPβ, and PGC1α in iWAT. Representative data are presented. (G) The data in F were quantified and analyzed. n = 5–7/group. Data are presented as means ± SEM. *, P < 0.05; **, P < 0.01; Student’s t test. A, AdipoRon; V and Veh, vehicle.
