Our study examined the relationship between the expression of matrix metalloproteinases (MMP)-1, MMP-2, and MMP-9 proteins and the pathogenesis of osteoarthritis (OA). We employed rigorous inclusion and exclusion criteria in computer-based bibliographic databases to extract published studies relevant to this investigation. The STATA 12.0 software was used for the statistical analyses. A ... more

Growth arrest and DNA-damage-inducible protein 45 alpha gene; meat quality; Pig; Single nucleotide polymorphism

This study was conducted to evaluate the porcine gene GADD45A (growth arrest and DNA-damage-inducible protein 45 alpha) as a positional candidate controlling quantitative trait loci (QTL) for meat quality traits on chromosome 6 (SSC6). Four exons of the porcine GADD45A gene were defined from cDNA and BAC clone sequences. A total of 4 single nucleotide ... more

ADSL; Intramuscular fat; Meat color; meat quality; Pig

In this study, meat quality traits were compared between Chinese lard- and European lean-type pigs. The association between expression of four genes (ADSL, GARS-AIRS-GART, DGAT1, and DECR1) and meat quality traits was also investigated. Meat quality traits were found to differ significantly between pig breeds. Meat color parameter values (a* and b*) and ... more

Glycolytic potential; meat quality; Mitochondria; Muscle fiber type; Tibetan pigs

The myosin heavy chain (MyHC) composition, glycolytic potential, mitochondrial content, and gene expression related to energy metabolism were analyzed in eight muscles from Tibetan pigs, to study how meat quality develops in different muscle tissues. The muscles were classified into three clusters, based on MyHC composition: masseter, trapezius, and latissimus dorsi ... more

Coat color; meat quality; Native pig breeds; PCR-RFLP; Vertebra number

Mutations in melanocortin 1 receptor (MC1R) gene and v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog (KIT) gene have been shown to affect coat color patterns in pigs. Additional functional marker genes, such as insulin like growth factor-2 (IGF2) and orphan nuclear receptor, germ cell nuclear factor (NR6A1), have been described for ... more

Carcass traits; Growth hormone; meat quality; Single nucleotide polymorphism; Swine

Marker-assisted selection has been widely used in breeding programs. The use of single nucleotide polymorphisms (SNPs) as genetic markers enables identification of genotypes that best contribute to quantitative characteristics. We evaluated a possible association between the DdeI growth hormone gene polymorphism and meat and carcass traits. A total of 476 halothane ... more

Candidate genes; meat quality; Nutrigenomics; Skeletal muscle; Transcriptomic

We examined the effect of lipid content in the diet on the transcriptome of the Longissimus dorsi muscle in pigs. Our objective was to examine changes at the molecular level affecting economically relevant meat quality characteristics such as intramuscular fat deposition and fatty acid profile. The treatments consisted of isoproteic and isoenergetic diets ... more

Gene association; Marbling score; meat quality; Pigs

The objective of this research was to identify candidate gene markers based on their function related to marbling score and meat quality traits in pigs. A total of 313 commercial pigs with five different Duroc (DR) breed fractions: 1 = 100%DR (n = 227), 2 = 50%DR x 50% Large white (LW)(n = 7), 3 = 50%DR x 50%Landrace (LR)(n = 41), 4 = 75%DR x 25%LW (n = 18), and 5 ... more

Calpastatin; meat quality; Meat tenderness; Myostatin; PCR-SSCP

In Brazil, most sheep are of the Santa Inês breed, which shows rusticity in breeding and grazing systems, being able to offer better adaptation characteristics for animals with meat production ability, such as the Texel and Dorper sheep. They can also improve meat production in animals that have better characteristics for milk production, such as Lacaune and East ... more

Myostatin (MSTN) is expressed in the myotome and developing skeletal muscles, and acts to regulate the number of muscle fibers. Wuding chicken large body, developed muscle, high disease resistance, and tender, delicious meat, and are not selected for fast growth. Broiler chickens (Avian broiler) are selected for fast growth and have a large body size and high muscle mass. Here, 240 one-day-old ... more
