Effect of breed on fatty acid composition and lipogenic enzyme abundance in the subcutaneous adipose tissue of pigs (2013)
Journal Article

This study investigated the role of lipogenic enzyme expression in breed-specific fat deposition in pigs. Objectives: (i) determine effect of breed on the relative abundance of the key lipogenic enzymes stearoyl-CoA desaturase (SCD), delta-6 desatura...

Differential effects of reduced protein diets on fatty acid composition and gene expression in muscle and subcutaneous adipose tissue of Alentejana purebred and Large White ×â Landrace ×â Pietrain crossbred pigs (2013)
Journal Article

The present study assessed the effect of pig genotype (fatty v. lean) and dietary protein and lysine (Lys) levels (normal v. reduced) on intramuscular fat (IMF) content, subcutaneous adipose tissue (SAT) deposition, fatty acid composition and mRNA le...

Hepatic lipogenic enzyme expression in pigs is affected by selection for decreased backfat thickness at constant intramuscular fat content (2013)
Journal Article

This study investigated (i) whether genetic selection for decreased backfat thickness at constant intramuscular fat (IMF) affects the expression of lipogenic enzymes in pig liver and (ii) whether expression of the hepatic lipogenic enzymes is related... Read More about Hepatic lipogenic enzyme expression in pigs is affected by selection for decreased backfat thickness at constant intramuscular fat content.

Fatty acid composition and lipogenic enzyme protein expression in subcutaneous adipose tissue of male pigs vaccinated against boar taint, barrows, and entire boars (2013)
Journal Article

Objectives of this study were to compare fatty acid composition of subcutaneous adipose tissue of entire boars, barrows, and male pigs vaccinated against boar taint with a vaccine containing a GnRH analogue-protein conjugate (Improvac, Pfizer Animal... Read More about Fatty acid composition and lipogenic enzyme protein expression in subcutaneous adipose tissue of male pigs vaccinated against boar taint, barrows, and entire boars.

Effect of pig breed and dietary protein level on selected fatty acids and stearoylcoenzyme A desaturase protein expression in longissimus muscle and subcutaneous fat (2013)
Journal Article

The aims of the study were 1) to investigate effects of a low protein diet on fatty acids content and composition of the LM and subcutaneous adipose tissue in 3 genetically diverse breeds, Large White × Landrace, Alentejano, and Bizaro, and 2) to det...

Investigation of Testosterone, Androstenone, and Estradiol Metabolism in HepG2 Cells and Primary Culture Pig Hepatocytes and Their Effects on 17βHSD7 Gene Expression (2012)
Journal Article

Steroid metabolism is important in various species. The accumulation of androgen metabolite, androstenone, in pig adipose tissue is negatively associated with pork flavor, odour and makes the meat unfit for human consumption. The 17β-hydroxysteroid d...

Influence of oilseed supplement ranging in n-6/n-3 ratio on fatty acid composition and δ5-, δ6-desaturase protein expression in steer muscles (2012)
Journal Article

This study investigated effects of roasted or extruded oilseed supplementation ranging in n-6/n-3 ratios from 0.3 to 5.0 on the fatty acid composition and expression of delta-5 desaturase (δ5d) and δ6-desaturase (δ6d) protein in commercial steer chee...

Expression of the hepatic skatole- and androstenone-metabolising enzymes in entire male pigs of two live weights (2012)
Journal Article

The aim of the present study was to investigate an in vivo relationship between increased levels of testicular steroids and protein expression of the key enzymes involved in hepatic metabolism of skatole (cytochrome P4502E1 and CYP2E1 and CYP2A) and... Read More about Expression of the hepatic skatole- and androstenone-metabolising enzymes in entire male pigs of two live weights.

Relationship between the hepatic SULT2A1 protein expression and backfat androstenone level in pigs of three breeds (2010)
Presentation / Conference Contribution

Excessive accumulation of androstenone in pig adipose tissue contributes to the phenomenon of boar taint, an off-odour of some cooked pork. One of the reasons for high androstenone accumulation is a low rate of androstenone metabolism in pig liver. T...

Effect of dietary fatty acids on expression of lipogenic enzymes and fatty acid profile in tissues of bulls (2010)
Journal Article

This study investigated the effects of dietary linolenic acid (C18:3n-3) v. linoleic acid (C18:2n-6) on fatty acid composition and protein expression of key lipogenic enzymes, acetyl-CoA carboxylase (ACC), stearoyl-CoA desaturase (SCD) and delta 6 de...

Comparison of two derivatisation methods for conjugated linoleic acid isomer analysis by Ag+-HPLC/DAD in beef fat (2010)
Journal Article

Two different procedures for the methylation of conjugated linoleic acid isomers (CLA) were compared by silver ion (Ag+)-HPLC. The base-catalysed method followed by an acid-catalysed method (NaOCH3/ BF3), and base hydrolysis followed by methylation w...
