摘要:

本研究以鸡原始生殖细胞(Primordial germ cells,PGCs)为材料进行Piwi基因的干扰,并探究Piwi和生殖特异性标记基因CVHDazlCDH及调控干细胞多能性转录因子基因Sox2、NanogPouV间的关系。由孵化至19期的鸡胚分离出PGCs,经鉴定后,利用RNA干扰技术抑制Piwi基因表达,相对实时荧光定量PCR检测目的基因的表达。结果发现,体外抑制Piwi后,CVHDazlNanog表达量显著增加(P<0.05),PouVSox2表达量显著下降(P<0.05),CDH表达量变化不显著(P>0.05)。本研究在家禽PGCs中建立Piwi基因干扰模型,并发现其干扰后影响生殖特异性标记基因和干性转录因子的表达,为其在生殖生物学中的功能研究提供了新的依据。

Abstract:

This study was designed to interfere Piwi gene in chicken primordial germ cells (PGCs) and explore its interaction with CVHDazlCDH, Sox2, Nanog and PouV genes.PGCs was isolated from 19 stage chicken embryo,and after identification of PGCs,we analyzed expression of CVHDazlCDHNanogSox2 and PouV under the condition of Piwi interference in PGCs by using real time quantitative PCR.The results showed that expression of CVHDazl and Nanog genes increased significantly(P<0.05),while the expression of PouV and Sox2 genes decreased significantly followed with Piwi interference in PGCs (P<0.05).Collectively,we constructed a Piwi gene interference model in vitro and found,and which influenced expression of CVHDazlCDH, Sox2,Nanog and PouV,which provided new basis for studying Piwi gene function in reproductive biology.
