Modulation of arginine-induced insulin and glucagon secretion by the hepatic vagus nerve in the rat: effects of celiac vagotomy and administration of atropine.

abstract：:To study the transcriptional regulation of the vasopressin gene in vitro, 3 kb of the 5' regulatory region of the rat vasopressin gene was isolated and subcloned, along with a series of various deletion mutants, into vectors containing the luciferase reporter gene. After transfecting these genes transiently into the h...
