Effect of nocturnal light exposure and liver denervation on the enzyme/receptor expression of peripheral tissues.

<p>Effects of a 1 h light exposure at either CT14 or CT20 on the expression of enzymes/receptor genes in different organs of liver-intact (control) and liver-denervated (CD) animals. Gray bars represent the non-light-exposed animals (n = 8 at CT14 and n = 6 at CT20) and white bars represent the light-exposed animals (n = 9 at CT14 and n = 6 at CT20). Hatched bars represent the liver denervated groups (non light-exposed group, n = 4, light-exposed group CD, n = 6). Note that the effect of light on hepatic Per1, Per2, GLUT2 and PEPCK is absent in denervated rats. Each value is the mean±S.E.M. * P<0.05, ** P<0.01, *** P<0.005, compared to the non-light-exposed control group; ∧∧∧ P<0.005, compared to the non-denervated control group.
