摘要 为研究miR-3880对奶山羊OGR1基因的靶向调节作用,试验选用泌乳期奶山羊乳腺上皮细胞为研究材料,采用生物信息学和双荧光素酶报告载体试验,初步确定OGR1为miR-3880的靶基因。利用RT-qPCR和Westernblot方法进一步研究miR-3880对OGR1的靶向作用。结果显示,miR-3880通过与OGR1基因3ˊUTR结合调控其mRNA和蛋白的表达。本试验为研究miR-3880对乳腺上皮细胞泌乳功能的调节作用提供试验基础。 In order to study the targeted regulation of miR-3880 on the OGR1 gene in dairy goats,the mammary epithelial cells of lactating dairy goats were selected as the research materials.The bioinformatics and dual luciferase reporter vector experiments were used to determine the OGR1 as the target gene of miR-3880.The targeting effect of miR-3880 on OGR1 was further investigated by RT-qPCR and western blot.The results showed that miR-3880 regulated the expression of mRNA and protein by binding to the OGR1 gene 3ˊUTR.This experiment provides a basis for studying the regulation of miR-3880 on the lactation function of mammary epithelial cells.
