Short summary
We present a novel study of the effect of bta-miR-33a on lipid metabolism in bovine mammary epithelial cells (BMECs). The correlation between bta-miR-33a and target gene ELOVL6 is also verified by a luciferase reporter assay. We show that bta-miR-33a directly inhibits the expression of ELOVL6 in BMECs, altering the mRNA expression of relative genes. This suggest that bta-miR-33a regulates lipid metabolism by targeting ELOVL6, which might be a potential molecular marker of milk fat composition.
