Diurnal expression patterns of clock genes and PDK4 in adipose tissue. Gene expression of selected clock genes (CLOCK, BMAL1, PER1, PER2, and REV-ERBα) and PDK4 normalized to GAPDH expression in subcutaneous adipose tissue obtained from metabolically healthy women (n = 10). Data are means ± SEM. ^†P < 0.05, ^‡P < 0.001, by using one-way repeated measures ANOVA.
