The expression of genes for fatty acid metabolism in dairy cows was studied by incubating mammary epithelial cells with LPS at 0, 0.1 or 10 ng mL-1 for 24 h using RT-qRCR in vitro. LPS increased transporter CD36 mRNA expression (p<0.01). FABP3 mRNA expression (p>0.05) was not affected by LPS but the FABP4 mRNA expression was affected (p<0.05), decreasing 0.79 fold when LPS was provided at 10 ng mL-1. Treatment with 0.1 ng mL-1 LPS tend to increased fatty acid synthesis enzyme FASN, ACACA, ACSS2 and fatty acid metabolism gene PPARG, PPARGC1A mRNA expression (0.10>p>0.05) compared with the control. LPS alters fatty acid metabolism, functioning as an important factor affecting milk fat synthesis. ER -
