Effect of chronic alcohol consumption and hepatocyte-specific Bmal1 gene deletion on glycogen metabolism genes. Diurnal gene expression profiles of glycogen synthase 2 (Gys2; A and E), glycogen phosphorylase (Pygl; B and F), glycogen synthase kinase 3β (Gsk3b; C and G), and protein phosphatase 1 catalytic subunit (Ppp1cc; D and H) were determined in livers collected from control and alcohol-fed hepatocyte-specific BMAL1 knockout (HBK; E–H) and control genotype (Con; A–D) mice at ZT 3, 7, 11, 15, 19, and 23 h (ZT 0: lights on; ZT 12: lights off, gray shading). mRNA levels were normalized to Gapdh and are displayed as a fold-change from the trough of Con mice fed the control diet. Data are fitted to a cosine function and expressed as means ± SE for n = 5–8 mice/genotype/diet/time point. Solid lines indicate a significant cosine curve fit, whereas dashed lines indicate a nonsignificant fit. Results for Cosinor and ANOVA analyses are provided in Tables 5 and 6, respectively.
