摘要: 本研究旨在检测miR-193b及其靶基因Kit在不同毛色羊驼皮肤中的表达,并分析它们与羊驼毛色的关系。试验以不同毛色的成年羊驼为研究对象,应用实时荧光定量PCR技术(QRT-PCR)对miR-193b及Kit在不同毛色羊驼皮肤中的相对表达量进行检测。结果显示,miR-193b在棕色羊驼中显著表达,其相对表达量是白色羊驼的1.741346倍;而Kit在白色羊驼中显著表达,其相对表达量是棕色羊驼的4.6029倍。通过以上研究结果显示miR-193b及其靶基因Kit可能参与羊驼毛色形成过程。提示,miR-193b可能通过负调控Kit参与羊驼毛色形成。

Abstract: This experiment was conducted to explore the expression of miR-193b and Kit in different colors of alpaca skin. The tissues were obtained from adult alpaca skins of white and brown hair colors. The comparative expression quantity of miR-193b and Kit in different hair colors was analyzed by real time quantitative PCR. The results of QRT-PCR showed that the comparative expression level of miR-193b in brown alpacas was 1.741346 times than that in white ones, and the comparative expression level of Kit in white alpacas was 4.6029 times than that in brown ones. The findings showed that miR-193b and its target gene Kit might involved in the regulation of hair color formation and miR-193b might regulate the formation of coat color by downregulating the expression of Kit.
