Expression of lipid metabolism and myosin heavy chain genes was evaluated in skeletal muscle of pig’s genotypes submitted to different dietary digestible lysine contents. Fifty-two barrows and fifty gilts from three genotypes (G: Piau, Duroc and Pietrain crossbreds) were assigned to three dietary digestible lysine conten.. Read More»

Delta-6 fatty acid desaturases are rate-limiting desaturases involved in metabolic processes of fatty acids, and they are encoded by the FADS2 gene. In the current study, an F2 resource population of Gushi chickens crossed with Anak broilers was used to investigate the genetic effects of the chicken FADS2. Two adjacent single .. Read More»

Fatty acid desaturases exist in all living organisms and play important roles in many different biologic processes, such as fatty acid metabolism, lipid biosynthetic processes, and pheromone biosynthetic processes. Using the available silkworm genome sequence, we identified 14 candidate fatty acid desaturase genes. Eleven gene.. Read More»

Adipose tissue plays an important role in energy metabolism and related diseases. The content of intramuscular fat significantly influences the pork quality. In this study, the whole gene expression of dorsal subcutaneous (s.c.) adipose tissue and intramuscular (i.m.) adipose tissue isolated from longissimus dorsi muscle tissue were compared using Affymet..

The sterol regulatory element binding factor 1 gene (SREBP1) plays an important role in the biosynthesis of fatty acids and cholesterol, and in lipid metabolism. The objective of this study was to investigate the effect of genetic polymorphisms of SREBP1 on the fatty acid composition of muscle and carcass traits in Simmental bulls and Snow Dragon black ca..

The tung tree (Vernicia fordii Hemsl.; Vf) has great potential as an industrial crop owning to its seed oil that has multiple uses. Diacylglycerol acyltransferases (DGATs) catalyze the last and most committed step of triacylglycerol (TAG) biosynthesis. In order to examine the physiological role of the VfDGAT2 gene in the tung tree, we characterized its ex.. Read More»

ntramuscular fatty acid (FA) is related to meat qualities such as juiciness, tenderness, palatability, and shear force. PPARα plays an important role in lipid metabolism in the liver and skeletal muscle. This study investigated FA composition in yaks and cattle, in order to ascertain whether a correlation between PPARα signal pathway genes as .. Read More»

Lack of continuous progress in Theobroma cacao (Malvaceae) breeding, especially associated with seed quality traits, requires more efficient selection methods based on genomic information. Reverse transcript quantitative PCR (RT-qPCR) has become the method of choice for gene expression analysis, but relative expression analysi.. Read More»

A time-course feeding trial was conducted for 120 days on juvenile channel catfish (Ictalurus punctatus) to study the effects of diets differing in oil source (fish oil or soy oil) and supplementation with a commercial probiotic. Relative levels of Δ6-fatty acid desaturase (Δ6-FAD) and fatty acid elongase (FAE) expression were assessed in brai.. Read More»

In Gucheng Lake, Jiangsu Province, China, randomly selected crabs were fed 2 diet types. Crab crude oil methyl ester analysis was performed using gas chromatography-mass spectrometry. Fatty acid compositions in the 3 edible parts of a crab - the hepatopancreas, gonad, and muscle - were analyzed. C16:1 and C18:2 were significantly higher in most commercial.. Read More»
