Effects of gestational chronic phase shift of photoperiod on intraperitoneal glucose tolerance test (A, C, E) and intraperitoneal insulin tolerance test (B, D, F) of rats fed with 45% high-fat diet (HFD) for 12 weeks, measured at week 0/basal (A, B), 6 weeks (C, D) and 12 weeks (E, F). Data are mean ± SEM. Solid line: LD, adult rats that had been gestated under control 12:12 (LD) photoperiod; dashed line: CPS, adult rats that had been gestated under chronic phase shift (CPS) photoperiod. AUC, Area under the curve; AAC, Area above the curve. n = 8 per group. *different from LD (p < 0.05 pairwise comparison at each time point with Bonferroni correction), ^#different from LD (p < 0.05, unpaired t-test).
