Relationship between the expression of key lipogenic enzymes, fatty acid composition, and intramuscular fat content of Limousin and Aberdeen Angus cattle (2010)
Journal Article

The amount and fatty acid composition of intramuscular fat (IMF) are major factors in determining the nutritional value of beef. Understanding the mechanisms regulating IMF formation is important for designing strategies for manipulation of IMF quant...

Acetyl-CoA carboxylase and stearoyl-CoA desaturase protein expression in subcutaneous adipose tissue is reduced in pigs selected for decreased backfat thickness at constant intramuscular fat content (2009)
Journal Article

The objectives of this study were 1) to determine whether selection toward less subcutaneous fat thickness at constant intramuscular fat content in pigs is related to tissue-specific changes in the expression of lipogenic enzymes acetyl-CoA carboxyla...

Effect of supplementation of the maternal diet with fish oil or linseed oil on fatty-acid composition and expression of δ5- and δ6-desaturase in tissues of female piglets (2009)
Journal Article

The present study investigated whether enrichment of the pig maternal diet with n-3 polyunsaturated fatty acids (PUFA) affects the fatty-acid composition of female piglets via enhancing of expression of the lipogenic enzymes 5-desaturase (5d) and 6-d...

Δ 9 desaturase protein expression and fatty acid composition of longissimus dorsi muscle in lambs fed green herbage or concentrate with or without added tannins (2009)
Journal Article

The aims of this study were to investigate the effect of feeding system and of supplementation of tannins (8.93% DM) on the relationship between intramuscular fat content, fatty acid composition and Δ 9 desaturase (Δ 9 d) protein expression in longis...

Effect of sex steroids on expression of sulfotransferase 2B1 immunoreactive protein in primary cultured porcine hepatocytes (2008)
Journal Article

An excessive accumulation of androstenone (5α-androst-16-en-3-one) in pig adipose tissue is one of the two major contributors to the phenomenon of boar taint. High levels of adipose tissue androstenone have been related to a low rate of hepatic andro...

Effect of testosterone, estrone sulphate and androstenone on 3β-hydroxysteroid dehydrogenase protein expression in primary cultured hepatocytes (2008)
Journal Article

Androstenone (5α-androst-16-en-3-one) is a steroid pheromone, excessive accumulation of which in pig adipose tissue contributes to the phenomenon of "boar taint". The incidence of boar taint increases with age and weight of entire male pigs. One of t...

Regulation of CYP2A6 protein expression by skatole, indole, and testicular steroids in primary cultured pig hepatocytes (2008)
Journal Article

CYP2A6 is one of the enzymes involved in the hepatic metabolism of a naturally produced compound, skatole, in the pig. Low CYP2A6 activity has been linked to excessive accumulation of skatole in pig adipose tissue and development of the phenomenon "b...

Expression of 3β-hydroxysteroid dehydrogenase, cytochrome P450-c17, and sulfotransferase 2B1 proteins in liver and testis of pigs of two breeds: Relationship with adipose tissue androstenone concentration (2007)
Journal Article

An excessive accumulation of androstenone in pig adipose tissue is a major contributor to the phenomenon of boar taint. Androstenone deposition is dependent on the rate of androstenone biosynthesis in testis and androstenone degradation in liver. The...

Relationship between carcass weight, adipose tissue androstenone level and expression of the hepatic 3β-hydroxysteroid dehydrogenase in entire commercial pigs (2007)
Journal Article

Boar taint is a major meat-quality defect in pigs and is due to excessive accumulation of skatole and androstenone in adipose tissue. The present work investigated the relationship between carcass weight, levels of skatole and androstenone in adipose...
