Several long-chain fatty acids (LCFA) are natural ligands of nonruminant peroxisome proliferator-activated receptor-gamma (PPARG), which, along with its lipogenic target genes, is upregulated in bovine mammary tissue during lactation. Thus, PPARG might represent an important control point of bovine milk fat synthesis. We tested lipogenic gene network(More)
The objective of this study was to assess the relationship between individual milk fatty acids (FA) and diet-induced milk fat depression (MFD) using principal component analysis (PCA) and multivariate analysis (MA). Cow treatment observations (n = 63) from 3 published feeding experiments with lactating dairy cows were used in the analyses. In the PCA,(More)
Dietary lipid supplements affect mammary lipid metabolism partly through changes in lipogenic gene expression. Quantitative PCR (qPCR) is a sensitive, reliable, and accurate technique for gene expression analysis. However, variation introduced in qPCR data by analytical or technical errors needs to be accounted for via normalization using appropriate(More)
The objectives were to determine the effect of stearoyl-CoA desaturase (SCD1) inhibition on adipocyte proliferation, differentiation and cellular lipid metabolism in bovine primary adipocytes. Inhibition of SCD1 activity by sterculic acid (SA) or conjugated linoleic acid, trans-10 cis-12 isomer, (t10, c12-CLA) did not alter adipocyte cellular proliferation,(More)
Our objectives were to: (1) confirm elongation products of palmitoleic acid (16:1 cis-9) elongation in vitro using stable isotopes and (2) evaluate if exogenous supplementation of palmitoleic acid, elongation products, or both are responsible for decreased desaturation and lipogenesis rates observed with palmitoleic acid supplementation in bovine(More)
Milk lipid is secreted by a unique process, during which triacylglycerol droplets bud from mammary cells coated with an outer bilayer of apical membrane. In all current schemes, the integral protein butyrophilin 1A1 (BTN) is postulated to serve as a transmembrane scaffold, which interacts either with itself or with the peripheral proteins, xanthine(More)
The biological activities and mechanisms of action of individual transoctadecenoic acids (trans-18:1 FA) have not been completely elucidated. We examined the effects of several individual trans-18:1 FA isomers and trans-10, cis-12 conjugated linoleic acid (CLA) on fat synthesis, and expression of lipogenic genes in mammary and liver tissue in lactating(More)
The objective of this study was to compare the effects of abomasal infusion of butterfat containing all fatty acids (FA) present in milk, including the short- and medium-chain FA, with infusion of only the long-chain FA (LCFA) present in milk, on the FA composition and milk fat yield in lactating dairy cows. Eight rumen-fistulated Holstein cows, in early(More)
Intramyocellular accumulation of lipids is often associated with insulin resistance. Deficiency of comparative gene identification-58 (CGI-58) causes cytosolic deposition of triglyceride (TG)-rich lipid droplets in most cell types, including muscle due to defective TG hydrolysis. It was unclear, however, whether CGI-58 deficiency-induced lipid accumulation(More)
Palmitelaidic (C16:1 trans-9) acid has been suggested to have beneficial effects on human health, including reduced adiposity. Objectives of this research were to quantify the amounts of palmitelaidic acid in beef samples and determine the effect of palmitelaidic acid supplementation on lipogenesis in bovine preadipocytes and adipocytes in vitro.
