This study analyzed effects of vegetable oils fed to dairy cows on abundance of genes related to lipid metabolism in milk somatic cells (MSC). During 63 days, 15 cows were allocated to 3 treatments: a control diet with no added lipid the same diet supplemented with olive oil (OO, 30 g/kg DM) or hydrogenated vegetable oil (HVO, 30 g/kg DM). On days 21, 42 and 63, MSC were obtained from all cows. Relative abundance of genes involved in lipid metabolism in MSC from cows fed control on days 42 and 63 was compared with relative abundance at day 21 to evaluate fold-changes. Those genes without changes over the time were selected to analyze effects of OO and HVO. Compared with control, on day 42, PLIN2 and THRSP were upregulated by OO. Compared with control, on day 21, HVO up regulated ACACA, down regulated FABP3, and on day 63 THRSP and FABP4 were down regulated. Dietary oil supplementation (3\% DM) had a modest nutrigenomic effect on different biological functions such as acetate and FA activation and intra-cellular transport, lipid droplet formation, and transcription regulation in MSC.}, doi = {10.3390/ani10010057}, eissn = {2076-2615}, issue = {1}, journal = {Animals}, publicationstatus = {Published}, publisher = {MDPI}, url = {https://nottingham-repository.worktribe.com/output/3637527}, volume = {10}, year = {2020}, author = {Vargas-Bello-pérez, Einar and Geldsetzer-Mendoza, Carolina and Cancino-Padilla, Nathaly and Morales, María Sol and Leskinen, Heidi and Garnsworthy, Philip C. and Loor, Juan J. and Romero, Jaime} }
