鸡原始生殖细胞(PGC)的独特特性为转基因动物的产生提供了潜在的策略,然而,PGC的不足限制了其应用。骨形态发生蛋白4(BMP 4)是PGC形成的关键因子,对BMP 4的调控可能为PGC的产生提供新的策略。我们在这里确定了一个长的非编码RNA(lncRNA)的目标BMP 4(LncBMP 4)。LncBMP 4具有与BMP 4类似的功能,因为它促进PGCs的形成和迁移。LncBMP 4通过吸附miRNA gga‐mir‐12211促进BMP 4表达,从而降低其对BMP 4表达的抑制作用。此外,LncBMP 4编码的小肽EPC 5促进BMP 4的转录。LncBMP 4的竞争性内源性RNA(ceRNA)效应需要N6-甲基腺苷(m6 A)修饰,以剂量依赖性方式进行,高水平的m6 A修饰会阻碍EPC 5翻译。了解LncBMP 4在PGC形成过程中促进BMP 4表达的分子机制可能为有效的PGC生成提供新的途径。
The unique characteristics of chicken primordial germ cells (PGCs) provide potential strategies for transgenic animal generation; however, insufficient PGC availability has limited their application. Regulation of bone morphogenic protein 4 (BMP4), a crucial factor for PGCs formation, may provide new strategies for PGC generation. We here identify a long noncoding RNA (lncRNA) that targets BMP4 (LncBMP4). LncBMP4 has similar functions as BMP4, in that it facilitates the formation and migration of PGCs. LncBMP4 promotes BMP4 expression by adsorbing the miRNA gga‐mir‐12211, thus reducing its inhibitory effect on BMP4 expression. In addition, the small peptide EPC5 encoded by LncBMP4 promotes the transcription of BMP4. The competing endogenous RNA (ceRNA) effect of LncBMP4 requires N6‐methyladenosine (m6A) modification, in a dose‐dependent manner, and high levels of m6A modification hinder EPC5 translation. Understanding the molecular mechanisms through which LncBMP4 promotes BMP4 expression during PGC formation may provide new avenues for efficient PGC generation.
