Fatty acid-binding proteins (FABPs) are members of the superfamily of lipid-binding proteins (LBP). So far 9 different FABPs, with tissue-specific distribution, have been identified: L (liver), I (intestinal), H (muscle and heart), A (adipocyte), E (epidermal), Il (ileal), B (brain), M (myelin) and T (testis). The primary role of all the FABP family members(More)
New molecular techniques focused on genome analysis open new possibilities for complex evaluation of economically important traits in farm animals. Milk production traits are typical quantitative characteristics controlled by a number of genes. Mutations in their sequences may alter animal performance as well as their breeding values. In this study, we(More)
Chromosomal localization of nine porcine genes encoding transcription factors involved in adipogenesis was determined. BAC clones harboring sequences of selected genes CEBPA (SSC6q12), CEBPB (SSC17q23), CEBPD (SSC4q15), CEBPG (SSC6q12), PPARG (SSC13q24), SREBF1 (SSC10q17), DDIT3 (SSC12q15), GATA2 (SSC13q24 -->q31) and GATA3 (SSC5p12) were mapped by FISH.(More)
In the present study cytogenetic localization of eight fatty acid binding protein genes in the pig genome was shown. BAC clones, containing sequences of selected genes (FABP1, FABP2, FABP3, FABP4, FABP5, FABP6, FABP7 and FABP8) were derived from porcine BAC libraries and mapped by FISH to porcine chromosomes (SSC) 3q12, 8q25, 6q26, 4q12, 4q12, 16q22, 1p22(More)
Associations between FABP3 (alternatively named H-FABP) gene polymorphisms and fatness traits were tested in two pig breeds (Polish Large White and Polish Landrace) and one synthetic line - 990. Three known single nucleotide polymorphisms, detected by HinfI, MspI and HaeIII restriction enzymes, were analyzed. Moreover, three new polymorphisms in the 5'(More)
Maternal diet during gestation can exert a long-term effect on the progeny’s health by programming their developmental scheme and metabolism. The aim of this study is to analyze the influence of maternal diet on lipid metabolism in 10- and 16-week-old rats. Pregnant dams were fed one of four diets: a normal protein and normal folic acid diet (NP-NF), a(More)
Complex traits, including those involved in diet-related diseases, are determined by multiple genes and environmental influences. Factors influencing the development of complex traits should be expanded to include epigenetic factors, such as DNA methylation, which occurs in utero. Epigenetic factors regulate gene expression and thereby cell differentiation(More)
OBJECTIVE Serum homocysteine levels show interindividual variation and are determined by nutritional factors, such as B-vitamin intake, and by age and genetic influences, such as the genotype of the methylenetetrahydrofolate reductase (MTHFR) gene. Recently, the relation between one-carbon and lipid metabolism has been shown. Therefore, we hypothesized that(More)
In the present study we show FISH localization of 4 porcine BAC clones harbouring potential candidate genes for fatness traits:DGAT1 (SSC4p15),PPARA (SSC5p15),ADIPOR1 (SSC10p13) andCREB (SSC15q24). Until now theCREB andADIPOR1 genes are considered to be monomorphic,DGAT1 is highly polymorphic, while for thePPARA gene only 1 SNP was identified. Assignment of(More)
Although maternal, fetal, and placental mechanisms compensate for disturbances in the fetal environment, any nutritional inadequacies present during pregnancy may affect fetal metabolism, and their consequences may appear in later life. The aim of the present study is to investigate the influence of maternal diet during gestation on Fe, Zn, and Cu levels in(More)
