Abstract: Fat deposition in cattle, influenced by factors such as genetics, age, sex, and nutrition, plays a crucial role in determining growth rates, beef yield, and meat quality. Among these, genetics is the predominant factor (Kim et al., 2020; Xing et al., 2025). Research indicates a high heritability for visceral (36%) and subcutaneous (57%) fat (Fox et al., 2012). Gene mutations that affect adipocyte function are significant contributors to variations in fat deposition and meat quality (Mannen, 2011; Mwangi et al., 2019; Sun et al., 2023; Dementieva et al., 2024). Therefore, investigating genetic variations in fat-related genes is essential for enhancing cattle performance.

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。
