β₂‐Adrenoceptor Agonists Induce the Mammalian Clock Gene, hPer1, mRNA in Cultured Human Bronchial Epithelium Cells in vitro

Abstract

The mammalian Per1 gene is one of the most important components of circadian clock function of the suprachiasmatic nucleus and peripheral tissues. We examined whether the β₂‐adrenoceptor agonists, procaterol and fenoterol, induce human Per1 mRNA expression in human bronchial epithelium. The in vitro stimulation of β₂‐adrenoceptor agonists in BEAS‐2B cells led to a remarkable increase in the level of hPer1 mRNA. Moreover, fenoterol or procaterol induced the phosphorylation of CREB in BEAS‐2B cells as verified by immunoblot analysis. β₂‐adrenoceptor agonists induced human Per1 mRNA expression by the signaling pathways of cAMP‐CREB in BEAS‐2B cells.
