Regulation of milk fat synthesis by dietary fatty acids
… the molecular mechanisms by which dietary fatty acids (FA) regulate lipogenic gene expression and milk fat synthesis. Principal component and multivariate analyses were conducted to establish the relationship between milk fat and FA concentrations in lactating cows fed milk fat depressing …

Regulatory factors of milk fat synthesis in dairy cows
… of these studies was to investigate the milk fat synthesis regulation by transcription factors. In the first study, bovine mammary epithelial (MAC-T) cells were treated with sterol regulatory element binding protein-1 (SREBP-1) specific siRNA. The mRNA and protein expression of SREBP-1 were …

Postruminal flow, digestibility, and utilization of fatty acylamides or conjugated linoleic acid for milk fat synthesis by lactating Holstein cows
… were used to evaluate the effects of dietary fatty acylamides (canolamide) or abomasally infused conjugated linoleic acid on milk production and composition. In the first experiment, cows were fed diets with no supplemental fat(control), or the control diet supplemented at 3.3% of DM with …

Identification of molecular targets regulating fatty acid synthesis in bovine mammary epithelial cells
Consumer demand for milk fat has declined due to the increased risk of cardiovascular disease associated with consuming a high saturated fat diet. Milk fat synthesis is energetically expensive for the dairy cow, especially during early lactation or periods of poor nutrition. Thus, manipulating milk …

Quantitative analysis of carbon fluxes for fat biosynthesis in wild-type and IRS-1 knockout brown adipocytes
Excessive fat synthesis and the subsequent dysregulation of lipid metabolism constitute the major pathological factors of obesity and type 2 diabetes through triggering insulin resistance. Thus, controlling fat synthesis by identifying key sites for regulation of lipogenesis and modulating the …

Effects of Dietary Conjugated Linoleic Acid Supplementation on Bovine Oocyte Lipid Metabolism, Lipid Composition and Embryo Cryotolerance
… was identified as a potent inhibitor of milk fat synthesis in lactating cows (Baumgard et al., 2000) and inclusion of CLA in bovine embryo culture medium improved post-thaw embryo survival (Pereira et al., 2007). Dietary supplementation of cows with CLA could alter oocyte fatty acid …

RELATIONSHIPS BETWEEEN CARBOHYDRATE NUTRITION AND METABOLISM, INFLAMMATION, AND PERFORMANCE OF DAIRY CATTLE DURING THE PERIPARTURIENT PERIOD
… negatively alter the rumen environment and milk fat synthesis.

Regulation of sterol regulatory element binding protein-1 in bovine mammary epithelial cells
… protein-1 (SREBP1) plays a central role in milk fat synthesis. SREBP1 stimulates the transcription of genes encoding lipogenic enzymes. The overall objective of these studies was to investigate the mechanisms of SREBP1 regulation by nutrients. In the first study, chromatin immunoprecipitation …

Transcriptional variation in muscle from cattle with alternative NCAPG/LCORL QTL genotypes
… an up- and downregulation of lean growth and fat synthesis pathways, respectively, associated with our list of differentially expressed genes; additionally, enrichment and activation of growth and metabolism related-pathways was reported for WGCNA Blue module. Our results suggest that LCORL …

Associations between gene variations and milk composition in New Zealand dairy cattle: A thesis submitted in fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… (NZ). Of the MS, increased production of milk fat and protein, would increase farm and industry income, and accordingly the production traits of milk volume, fat percentage and protein percentage are included in the National Breeding Objective. This is underpinned by the Breeding Worth (BW) …
