BACKGROUND The involvement of muscle triacylglycerol (TAG) storage in the onset of insulin resistance is questioned and the attention has shifted towards inhibition of insulin signalling by the lipid intermediate diacylglycerol (DAG). The enzyme 1,2-acylCoA:diacylglyceroltransferase-1 (DGAT1) esterifies a fatty acyl-CoA on DAG to form TAG. Therefore, the aim of the present study was to investig...
quantitative traits locus for milk production traits has been described on centromeric end of bovine chromosome 14. reports name the acyl coa: diacylglycerol acyltransferase (dgat1) gene as a potential candidate gene with dinucleotide substitution (aa to gc) in exon viii which causes the change of lysine to alanine in amino acid (k232a).the aim of the present study was to estimate the frequency...
diacylglycerol acyltransferase1 (dgat1) is a key enzyme in synthesis of triglycerides. a transition mutation resulting substitution of guanine by adenine in dgat1 gene and substitution of lysine by alanine in diacylglycerol-acyltransferase enzyme in cattle has a major effect on milk yield and milk composition traits. in this research, the polymorphism of the region spanning exon 3 to exon 17 of...
The diacylglycerol acyltransferase 1 gene (DGAT1) was identified as a strong candidate gene affecting mutton quality traits in sheep. Single nucleotide polymorphism creates a single base mutation (C to T) in AGCT site of endonuclease AluI. DGAT1 is one of the candidate genes to improve carcass characteristics in feedlot animals. In order to study area T487C in exon 17 of the DGAT1 polymorphism,...
The objective of this study was to estimate the effect of acylCoA-diacylglycerol-acyltransferase 1 (DGAT1), leptin and thyroglobulin (TG) loci on the milk fat, milk protein and milk yield in Holstein Friesian, Jersey and Hungarian Simmental cows. Leptin and DGAT1 genotypes were determined by qPCR assay, while TG genotypes were identified using the polymerase chain reaction-restriction fragment ...
Calorie restriction results in leanness, which is linked to metabolic conditions that favor longevity. We show here that deficiency of the triglyceride synthesis enzyme acyl CoA:diacylglycerol acyltransferase 1 (DGAT1), which promotes leanness, also extends longevity without limiting food intake. Female DGAT1-deficient mice were protected from age-related increases in body fat, tissue triglycer...
Diacylglycerol transferase is a microsome enzyme that plays an important role in glycerol lipid metabolism. The acyl CoA-diacylglycerol- acyltransferase 1 (DGAT1) is considered to be the key enzyme in controlling the synthesis of triglycerides in adipocytes. This enzyme catalyzes the final step of triglyceride synthesis (transform triacylglycerol (DAG) into triacylglycerol (TAG). The present st...
Acyl CoA:diacylglycerol acyltransferase (DGAT) is a ubiquitously expressed enzyme that catalyzes the final reaction in the major pathways of triglyceride synthesis. Mice lacking DGAT1 (Dgat(-/-)) demonstrate significant changes in lipid metabolism in several tissues, including the skin. Here we report the effects of DGAT1 deficiency on fur and sebaceous glands. Adult Dgat(-/-) mice had dry fur ...
The objective was to determine the single gene and interaction effect of composite genotype of beta-kappa casein and DGAT1 gene on milk yield (MY) and milk composition, content of milk fat (%FAT), milk protein (%PRO), solid not fat (%SNF), and total solid (%TS) in crossbred Holstein cows. Two hundred and thirtyone cows were genotyped with PCR-RFLP for DGAT1 and composite genotype data of beta-k...
Increased fat deposition in skeletal muscle is associated with insulin resistance. However, exercise increases both intramyocellular fat stores and insulin sensitivity, a phenomenon referred to as "the athlete's paradox". In this study, we provide evidence that augmenting triglyceride synthesis in skeletal muscle is intrinsically connected with increased insulin sensitivity. Exercise increased ...
