A novel mutation in the promoter region of RPL8 regulates milk fat traits in dairy cattle by binding transcription factor Pax6

Ribosomal protein L8 (RPL8) was considered as a promising candidate gene for the milk fat percentage trait in dairy cattle in our previous genome-wide association studies, but the mechanism remains to be determined. Here we investigated the molecular mechanism underlying the effect of bovine RPL8 on milk fat percentage. We demonstrated that RPL8 silencing in bovine mammary epithelial cells affected the expression of genes encoding fat-related...
