By using flow cytometry and Western blotting , we demonstrated that isoproterenol , S - propranolol , CGP - 12177 [ 4 - [ 3 - [ ( 1 , 1 - dimethylethyl ) amino ] 2 - hydroxypropoxy ] - 1 , 3 - dihydro - 2H - benzimidazol - 2 - one ] , pindolol , and timolol , which displayed agonistic properties toward the beta ( 1 ) AR in either the adenylyl cyclase or the mitogen - activated protein kinase signaling pathways , induced cleavage of the mature cell - surface receptor .
