Adenylosuccinate lyase (ADSL) and lipoprotein lipase (LPL) are key enzymes in the metabolism of inosine monophosphate (IMP) and fat mass, which are important factors in meat quality evaluation. In this study, we selected 50 hens from the ISA B-line layers and Guangxi Yellow chickens, slaughtered the chickens at 120 days old, and analyzed polymorphisms in the ADSL and LPL ... more
In this study, we identified myogenic regulatory factors (MRFs) and analyzed the correlation between MRFs and meat quality in rainbow trout. The MyoD1a and MyoD1b genes were cloned from rainbow trout using a homology cloning method. Introns 1 and 2 in the MyoD1a and MyoD1b genes were cloned and submitted to GenBank (accession Nos. ... more
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
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
The extracellular matrix (ECM) is the major macromolecule in skeletal muscle, which affects meat quality greatly. The remodeling of the ECM is mainly regulated by matrix metalloproteinases (MMPs). The expression patterns of MMP-1, -2, and -8 in longissimus dorsi muscle were explored using quantitative real-time polymerase chain reaction. The results show that the expression of MMP-1, -2 ... more
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
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
Polymorphism of CAST and GDF-8 genes and association with physical-chemical parameters of sheep meat
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
ASB15 is a member of the ankyrin repeat and suppressor of cytokine signaling box family, and is predominantly expressed in skeletal muscle. In the present study, an F2 resource population of Gushi chickens crossed with Anka broilers was used to investigate the genetic effects of the chicken ASB15 gene. Two single nucleotide polymorphisms (SNPs) (rs315759231 A>G and ... more
We assessed the role of single nucleotide polymorphisms (SNPs) in ERCC1 and ERCC2 genes in the clinical outcomes for osteosarcoma patients receiving cisplatin-based treatment. A perspective study was conducted on 260 patients with osteosarcoma during 2010 and 2011. A polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) assay was used to assess ... more
