【摘要】：鴿(Columba livia)是少數(shù)幾種能分泌營養(yǎng)液哺育雛鳥的鳥類之一。孵化期的親鴿嗉囊壁逐漸增厚,當雛鴿被孵出,親鴿嗉囊會產(chǎn)生鴿乳(crop milk)以哺育雛鴿。鴿乳的營養(yǎng)成分及其生物學功能與哺乳動物的乳汁相似,其產(chǎn)生過程受催乳素的調節(jié)。在催乳素作用下,嗉囊上皮細胞快速增殖脫落形成鴿乳,該過程可能與膜聯(lián)蛋白Icp35(Anx Icp35)等關鍵基因的轉錄以及JAK/STAT和Wnt等信號通路的激活有關。本文對鴿乳的主要成分、生物學功能和泌乳過程中嗉囊組織學變化進行了介紹,對鴿乳生成過程中特異的基因變化和分子調控機制進行了總結,以期為后續(xù)的相關研究工作提供有益的參考。
[Abstract]:The pigeon Columba livia is one of the few birds that secrete nutrients to feed their nestlings.The crop wall of the parent pigeon gradually thickened during the incubation period, and when the young pigeon was hatched, the crop of the parent pigeon would produce the pigeon milk crop milk) to feed the young pigeon.The nutritional composition and biological function of pigeon milk are similar to that of mammal milk, and its production process is regulated by prolactin.Under the action of prolactin, crop epithelial cells proliferate rapidly and shed off to form pigeon milk, which may be related to transcription of key genes such as Icp35(Anx Icp35 and activation of signal pathways such as JAK/STAT and Wnt.In this paper, the main components, biological functions and crop histological changes of pigeon milk during lactation were introduced, and the specific gene changes and molecular regulatory mechanisms during pigeon milk production were summarized.In order to provide a useful reference for the follow-up related research work.
