The affinity of 5-methyl-urapidil for alpha 1-adrenoceptors was determined from the inhibition of [3H]prazosin binding on membrane of different rat tissues. In hippocampus, vas deferens and heart 5-methyl-urapidil displaced [3H]prazosin in a biphasic manner with mean pKI values between 9.1

alpha(1)-Adrenoceptor has been discovered to exist in many human tissues and mediates important physiological functions. The purpose of this study was to detect the expression, distribution, and function of alpha(1)-adrenoceptor subtypes in human submandibular glands. alpha(1A)- and alpha(1B)-Adrenoceptor mRNAs were

The outward current flowing through the two-pore domain acid-sensitive potassium channel TASK-1 (I(TASK)) and its inhibition via alpha1-adrenergic receptors was studied in rat ventricular cardiomyocytes. Quantitative RT-PCR experiments were carried out with mRNA from rat heart. Patch-clamp recordings were performed
