The central clock is sufficient to drive circadian rhythms of hepatic transcription and to restore glucose tolerance. (A) Venn diagram representing the overlap of significantly oscillating (JTK, P < 0.01) liver transcripts between WT, Bmal1 KO mice, and Bmal1 BRE. (B) Heatmaps representing the oscillating transcripts in WT only (left heatmap), overlapping between WT and BRE (middle heatmap), and in BRE only (right heatmap). (C) Radar plots illustrating the phase of transcriptional oscillations in WT only (bottom left radar plot), overlapping between WT and BRE (top radar plot), and in BRE only (bottom right radar plot). (D) Graph displaying the amplitudes of the overlapping oscillating transcripts between WT and BRE. Significant difference was assessed by paired t test. (E) Pathway enrichment of oscillating transcripts overlapping between WT and BRE mice. (F) Oral glucose tolerance test (OGTT) and the calculated area under the curve (AUC) in all genotypes presented in the study. Significant differences were analyzed by a one-way analysis of variance (ANOVA) followed by the Fisher’s least significant difference post hoc test. *P < 0.05, **P < 0.01, ***P < 0.001, and ****P < 0.0001. All analyses were performed using at least n = 3 mice. Credit: Science Advances (2022). DOI: 10.1126/sciadv.abo2896
