It is known that anterior pituitary hormone prolactin(PRL) and posterior pituitary hormone arginine vasotocin(AVT) play important roles in the expression of courtship behavior of the male newt Cynops pyrrhogaster. In this study, we demonstrated that PRL has AVT releasing activity by the organ culture technique and up-regulates the expression of AVT precursor gene. Judging from the result of reporter gene assay using vasopressin V1a receptor antagonist and the localization of AVT V1a-type receptor in the newt brain, it was concluded that the AVT V1a-type receptor is one of the most important receptor in the courtship behavior induced by AVT.

垂体前叶激素催乳素（PRL）和垂体后叶激素精氨酸催产素（AVT）在雄性蝾螈求偶行为的表达中发挥着重要作用。本研究通过器官培养技术证明PRL具有AVT释放活性，并上调AVT前体基因的表达。从加压素V1a受体拮抗剂的报告基因检测结果和AVT V1a型受体在蝾螈脑中的定位来看，AVT V1a型受体是蝾螈诱导求偶行为中最重要的受体之一。 AVT。
