Fig. 2From: Histamine 1 receptor-Gβγ-cAMP/PKA-CFTR pathway mediates the histamine-induced resetting of the suprachiasmatic circadian clockH1R activation increases the cAMP level in the SCN through the Gβγ protein. Graph showing the effects on the content of cAMP in the mouse SCN tissue, of H1R (2-pyridylethylamine, 100 μM, n = 5 mice) and H2R (amthamine, 20 μM, n = 5 mice) agonists alone or in combination with the Gβγ inhibitor gallein (100 μM, n = 6 mice). Control: n = 5 mice. One-way ANOVA followed by Student-Newman-Keuls pairwise comparison test (*: p < 0.05)Back to article page
