摘要:

黑色素细胞对于毛色和肤色的形成具有至关重要的作用。黑色素细胞由胚胎时期的神经嵴干细胞分化而来,在成熟黑色素细胞内通过一系列复杂的酶催化反应最终生成黑色素,从而决定动物的毛色和肤色。黑色素的生成过程复杂,受到一些转录因子、激素、信号通路分子协同调控。microRNA(miRNA)是一类长约22 nt的内源性非编码RNA,主要通过抑制转录后的翻译过程来调控基因表达。越来越多的研究表明,miRNA与黑色素生成相关。本文对黑色素沉积相关的miRNAs的挖掘和鉴定工作以及miRNAs调控毛色和肤色的研究进展进行综述。

Abstract:

Melanocyte,generated from embryonic neural crest stem cells,plays important roles in coat and skin color formation.Melanin,the product of a series of enzyme catalyzed reactions in melanocyte,determines animal coat and skin color.Melanogenesis is a complex process involving coordinated regulation of some transcription factors,hormones and signaling pathway molecules.microRNA (miRNA) is a class of endogenous,non-coding,small RNA molecule (about 22 nt),which regulates gene expression mainly at the post-transcription level.More and more evidences demonstrated that miRNA involve in the regulation of melanogenesis.Herein,it was reviewed in this paper the studies on the discovery and identification of melanin-associated miRNAs,and the research progress of how miRNAs regulate animal coat and skin color.
