摘要: 卵泡发育是决定排卵率和产羔数的重要因素,直接影响母畜生殖机能和繁殖力高低。随着近年来组学技术的发展,微小RNA(microRNA,miRNA)和长链非编码RNA(long non-coding RNA,lncRNA)在反刍动物的卵泡动态发育过程中发挥了重要的调控作用。miRNA可以通过沉默或诱导靶基因表达参与颗粒细胞功能、卵母细胞成熟和卵泡发育的调控;lncRNA作为miRNA的分子海绵,通过竞争性结合miRNA间接调控基因表达,影响卵泡内的生殖细胞发育和卵巢功能。作者综述了miRNA和lncRNA在反刍动物卵泡发育中的分子功能和作用机制,并对miRNA、lncRNA和基因三者之间的竞争性内源RNA(competing endogenous RNA,ceRNA)互作网络进行归纳,为挖掘母畜繁殖力性状关键基因和分子育种工作提供可靠的基因资源和理论参考。

Abstract: Follicular development is an important factor in determining ovulation rate and lambing number,it directly affects the reproductive function and fecundity of maternal animals.With the development of omics technology in recent years,microRNA (miRNA) and long non-coding RNA (lncRNA) have played an important regulatory role in the dynamic development of follicle in ruminants.miRNA can participate in the regulation of granulosa cell function,oocyte maturation and follicular development by silencing or inducing the expression of target genes.lncRNA acts as a molecular sponge for miRNA and indirectly regulates gene expression by competitive binding to miRNA,affecting germ cell development and ovarian function within the follicle.The authors review the molecular function and mechanism of miRNA and lncRNA in follicle development of ruminants,and summarize the competitive endogenous RNA (ceRNA) interaction networks among miRNA,lncRNA and gene,in order to provide a reliable genetic resources and theoretical reference for excavating key genes for reproductive traits of maternal animals and carrying out molecular breeding work.
