Values are presented as means ± SE; n = 6–10. Two-way ANOVA was used to compare effects of PVAT and genotype with Tukey’s post hoc test for cumulative concentration–response curves to assess vasorelaxation and vasoconstriction (Fig. 3). symbols indicate statistically significant differences (P < 0.05) for post hoc tests showing differences within genotypes with (+) and without (−)PVAT. AUC, area under the curve; HBK, hepatocyte-specific Bmal1 knockout; ACh, acetylcholine; PE, phenylephrine; PVAT, perivascular adipose tissue; SNP, sodium nitroprusside.

P < 0.05 flox + PVAT vs. flox.

*P < 0.05 HBK + PVAT vs. HBK.
