circBDP1中A-G的新突变可影响牛脂肪细胞的增殖分化及胴体性状1西北农林科技大学动物科技学院, 中国杨凌, 712100 2安徽农业大学动物科技学院, 中国合肥, 230036 3山东省农业科学院畜牧兽医研究所, 中国济南, 250100 摘要:脂肪沉积是影响牛生长发育及肉产量和品质的重要因素。前期发现环状RNA circBDP1可促进牛脂肪细胞的增殖与分化。本研究通过鉴定circBDP1基因(rs454813519)上的A>G突变,采用Sanger测序与Kompetitive Allele-Specific PCR(KASP)技术,在秦川牛及山东黑牛遗传资源群体(Shandong Black Cattle Genetic Resource, SDBCGR)中检测到circBDP1-SNP位点的三种基因型(AA、AG和GG)。关联分析结果表明,该circBDP1-SNP A>G变异与SDBCGR母牛胸肌、上脑、牛肋排等性状和公牛胴体重、秦川牛体长等性状相关。为揭示该突变的相关功能,本研究构建了携带circBDP1-SNP不同等位基因的circBDP1-G/A过表达载体,并转染至牛前体脂肪细胞中。EdU检测、流式细胞术及qRT-PCR等实验结果显示,与circBDP1-G相比,circBDP1-A可显著增强前脂肪细胞的增殖与分化。此外,据已发表的全球牛基因组数据推测,G等位基因可能源自印度瘤牛。综上,circBDP1基因上的circBDP1-SNP A>G突变影响前脂肪细胞增殖与分化,可作为肉牛分子辅助选择的DNA标记。 关键词组: Darkslateblue:Affiliate; Royal Blue:Author; Turquoise:Article
