MYF6 gene codes for the bHLH transcription factor belonging to MyoD family. Its expression accompanies the processes of differentiation and maturation of myotubes during embriogenesis and continues on a relatively high level after birth, affecting the muscle phenotype. The porcine MYF6 gene was amplified and sequenced and compared with MYF6 gene sequences(More)
This study was performed in order to investigate a relationship between polymorphism's of calapastatin gene (CAST) identified with HinfI, MspI and RsaI restriction endonucleases in pigs and meat quality characteristics and also interactions between CAST and RYR1 genes. Investigations were carried out on group of 89 fatteners being crosses of (Polish Large(More)
Myogenic factor 5 (myf-5) is the product of theMYF5 gene, belonging to theMyoD family. This transcription factor participates in the control of myogenesis. We identified 3 new mutations in the promoter region of the gene:A65 C, C580T andC613T. The aim of this study was to evaluate the influence of theA65C transversion on gene expression. The analysis was(More)
Myogenic factor 3 (myf - 3) and myogenic factor 5 (myf - 5) are the products of genes: MYOD1 (MYF3) and MYF5, respectively, which belong to the MyoD family. These transcription factors control the processes of myogenesis. The fragments of both the genes comprising exons and promoters were amplified and sequenced. In the 5'UTR region of gene MYOD1, the G302A(More)
The aim of the study was to characterize the polymorphism of calpastatin (CAST) gene identified with three restriction enzymes (HinfI, MspI, RsaI) in several pig breeds and lines bred in Poland and to evaluate the relation between the CAST genotypes and carcass traits. The analyses covered a total of 294 fatteners of Polish Landrace (PL), Pietrain (P),(More)
Investigation was carried out on 96 [(Polish Large White × Polish Landrace) × (Duroc × Pietrain)] fatteners. The results concerning the influence CAST × RYR1 genes interaction on some meat quality parametres suggest that incidence of faulty, exudative meat appearing in some stress-resistant fatteners (CC genotype in relation to RYR1 locus) and also normal(More)

Genes MYOD1 and MYF5 of the MyoD family were considered as candidate genes for growth rate and carcass traits in pigs. Products of both genes are transcription factors with domain bHLH. A relation was estimated between new polymorphisms identified in the coding and 5’ flanking regions of both genes and productive traits of 216 gilts of synthetic Line 990.(More)
The aim of this study was to characterize the polymorphism of GH and LEP genes in selected pig breeds reared in Poland and to analyse the relation between the GH and LEP genotypes and carcass meat and fat deposition. The tests covered a total of 305 animals of the following breeds and lines: Pietrain (P), Złotnicka Spotted (ZS), Polish Landrace (PL), Torhyb(More)
MYOG andMYF6 belong to theMyoD gene family. They code for the bHLH transcription factors playing a key role in later stages of myogenesis: differentiation and maturation of myotubes. Three SNPs in porcineMYF6 and two in porcineMYOG were analysed in order to establish associations with chosen carcass quality and growth rate traits in Polish Landrace, Polish(More)
