摘要： ATP binding cassette subfamily A member 1 (ABCA1) is a membrane protein. As a member of the superfamily of ABC transporters, ABCA1 can transport lipids and cholesterol across cell membranes. To further verify the relationship between the ABCA1 gene and milk fat metabolism of Chinese Holstein dairy cows, we exploited transient transfection mediated-RNA interference technology to specifically knockdown expression levels of the endogenous gene ABCA1 in bovine mammary epithelial cells (BMECs) to analyse the effect on intracellular triglyceride (TG) content by quantitative real-time polymerase chain reaction (qRT-PCR), Western blot, cell TG Assay and RT2 Profiler PCR array. The results showed that ABCA1 knockdown reduced the TG content in BMECs. On the other hand, the RT2 Profiler PCR array demonstrated that the expression levels of 12 genes, including fatty acid binding protein 4 (FABP4), acyl-CoA dehydrogenase short/branched chain (ACADSB), ELOVL fatty acid elongase 3 (ELOVL3) and solute carrier family 27 member 1 (SLC27A1), were altered upon ABCA1 down-regulation using RNA interference (RNAi). Overall, ABCA1 expression influenced triglyceride metabolism in BMECs by regulating the expression of related genes in the lipid metabolism pathway.
