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

Calpastatin; Cyprinus carpio; Real-time PCR; Tissue expression

Calpastatin, an important protein used to regulate meat quality traits in animals, is encoded by the CAST gene. The aim of the present study was to clone the cDNA sequence of the CAST gene and detect the expression of CAST in the tissues of Cyprinus carpio. The cDNA of the C. carpio CAST gene, amplified using rapid amplification of cDNA ends ... more

Buffalo; Genotype; Milk; PCR-SSCP; SNP

Water buffaloes (Bubalus bubalis) are quite well adapted to climatic conditions in the Amazon, and in this biome, they are noted for the considerable amount of meat and milk they produce and how hard they are able to work. Because of a lack of research dedicated to improving the rearing of buffaloes in the Amazon, the objective of this study was to genetically characterize the ... more

Differential allelic expression; Meat tenderness; Nelore; Potassium inwardly rectifying channel

In contrast to the Mendelian inheritance model, parental alleles can contribute unequally to gene expression, which may result in phenotypic variance among individuals and bias in the predicted additive effect of molecular markers associated with production traits. Given the need to understand the effects of allelic variation and parent-of-origin effects on the expression of genes with a ... more

Meat tenderness; Six1; Six4; Tan sheep

Sine oculis-related homeobox 1 (Six1) and 4 (Six4) transcription factors are expressed in developing and adult muscle. These Six homeoproteins are required to activate the fast-type muscle program in the mouse primary myotome. Whether Six1 and Six4 genes have a role in meat tenderness in Tan sheep has not yet been established. To ... more

cDNA cloning; Chinese perch; Fasting-re-feeding; Gene expression; Myostatin

Myostatin (MSTN) is an important member of the transforming growth factor-β (TGF-β) superfamily and is a muscle growth inhibitor. In the present study, we cloned the Chinese perch MSTN cDNA sequence and analyzed its expression patterns under various conditions. The MSTN full cDNA sequence was 3347 bp long, including an open-reading frame of 1131 bp, which encoded 376 amino acids. Sequence ... 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
