1 It has been suggested that beta2-adrenergic receptor (beta2-AR)-mediated signaling induced by catecholamines regulates the degradation of p53. Catecholamines adrenoceptor beta 2 Homo sapiens
2 It has been suggested that beta2-adrenergic receptor (beta2-AR)-mediated signaling induced by catecholamines regulates the degradation of p53. Catecholamines adrenoceptor beta 2 Homo sapiens
3 In the present study, we demonstrated that catecholamines upregulated the expression of silent information regulator 1 (Sirt1) through activating beta2-AR-mediated signaling pathway, since selective beta2-AR antagonist ICI 118, 551 and non-selective beta-blocker proprenolol effectively repressed isoproterenol (ISO)-induced Sirt1 expression. Catecholamines adrenoceptor beta 2 Homo sapiens
4 In the present study, we demonstrated that catecholamines upregulated the expression of silent information regulator 1 (Sirt1) through activating beta2-AR-mediated signaling pathway, since selective beta2-AR antagonist ICI 118, 551 and non-selective beta-blocker proprenolol effectively repressed isoproterenol (ISO)-induced Sirt1 expression. Catecholamines adrenoceptor beta 2 Homo sapiens
5 In addition, we demonstrated that catecholamines induced resistance of cervical cancer cells to chemotherapeutics both in vitro and in vivo and that beta2-AR was overexpressed in cervical cancer tissues. Catecholamines adrenoceptor beta 2 Homo sapiens
6 Our data suggest that the p53-dependent, chemotherapeutics-induced cytotoxicity in cervical cancer cells may be compromised by catecholamines-induced upregulation of the Sirt1 expression through activating the beta2-AR signaling. Catecholamines adrenoceptor beta 2 Homo sapiens
