Previous results of fine mapping for quantitative trait loci affecting intramuscular fat content identified a 3.0-Mb chromosome interval on porcine chromosome 7, which contains at least 9 genes, based on the pig genome assembly. Therefore, we proposed these nine genes (LOC100154481, LOC100155711, LOC100155276, SPATA7, PTPN21, ZCH14, EML5, TTC8, and FOXN3) as positional candidate genes. The coding exons of the nine genes were characterized, and 45 polymorphisms were detected in F2 Duroc × Meishan population. Within the nine genes, 10 non-synonymous substitutions...

The myostatin (MSTN) gene was studied as a candidate genetic marker for growth traits. We investigated polymorphisms of the MSTN gene in 664 individuals from four goat populations and applied PCR-SSCP and DNA sequencing analysis to reveal two single nucleotide polymorphisms (DQ167575: g.368A>C (p.Lys49Thr) and g.4911C>T. At g.368A>Clocus, the frequencies of g.368A allele were 0.75-0.81, and the frequencies of g.368C allele were 0.19-0.25. At g.4911C>T locus, the frequencies of g.4911C allele were 0.76-0.82, and frequencies of g.4911T allele were 0.18-0.24. Compared to the female goats with AC genotype, those with...

A 2 × 3 factorial design experiment was conducted to evaluate the effect of adding lycopene (0 and 75 mg/kg) and vitamin E (0.50 and 100 mg/kg) to the diet of chickens. Moreover, the study investigated growth traits, oxidative stability and chemical composition of leg meat and the vitamin content of meat and liver. The study was conducted using five hundred and forty Ross 308 male broilers that were assigned to one of the six dietary treatments. Significant interactions between lycopene and vitamin E additions affected the body weight of 21-days-old chickens (P = 0.005), the malondialdehyde content in fresh leg meat (P < 0.001)...
Expression profiles of myostatin and calpastatin genes and analysis of shear force and intramuscular fat content of yak longissimus muscle

Czech J. Anim. Sci., 2011, 56(12):545-550 | DOI: 10.17221/4417-CJAS
The main objective of this study was to reveal the expression profiles of two negative regulators, myostatin (MSTN) and calpastatin (CAST)genes, of skeletal muscle growth in highland yaks (Bos grunniens). mRNA levels of both genes were quantified in different yak tissues by semi-quantitative RT-PCR to reveal the tissue expression pattern, and real-time quantitative RT-PCR was employed to compare the mRNA levels of MSTN and CAST in longissimus muscles of yaks at different ages and adult Yellow cattle. Intramuscular fat (IMF) content, tenderness and pH of longissimus muscle of yaks at different...
