Body weight; Cattle; Dapper1 gene; F-PCR-RFLP; Haplotype; SNPs

The Dapper1 protein plays important role in multiple developmental processes via negative modulation of the Wnt signaling pathway. We detected variations in Dapper1 in 1185 individuals from 5 Chinese cattle breeds and determined their effects on bovine body weight. Two silent mutations (g.8344C>T and g.8428C>T) in exon 6 along with two substitutions (g.10513A>G and g. ... more

Cattle; Gene; mutations; Polymorphism; Sequence; TNF-RII

Tumor necrosis factor receptor type II (TNF-RII) is a surface glycoprotein that can form a complex with TNF-α and participate in the body's immune response. Functions of TNF-RII are impaired in the pathogenesis of viral diseases. We analyzed sequences in the regulatory region of the TNF-RII gene in cattle. An attempt was also made to identify mutations that would have the greatest effect ... more

1711b satellite; Cattle; indicus; Microsatellites; mtDNA; taurus

Our objective was to estimate Bos primigenius taurus introgression in American Zebu cattle. One hundred and four American Zebu (Nellore) cattle were submitted to mtDNA, microsatellite and satellite analysis. Twenty-three alleles were detected in microsatellite analysis, averaging 4.6 ± 1.82/locus. Variance component comparisons of microsatellite allele sizes allowed the ... more

Cattle; Haplotype; Polymorphism; Short tandem repeat; Y-chromosome

The aim of this study is to use Y-chromosome gene polymorphism method to investigate regional differences in genetic variation and population evolution history of the Chinese native cattle breeds. Six Y-chromosome short tandem repeat (Y-STR) loci (UMN0929, UMN0108, UMN0920, INRA124, UMN2404, and UMN0103) were analyzed using 1016 healthy ... more

Bos taurus indicus; Cattle; InDel; Polymorphism; Traceback

Brazil is a major producer and exporter of beef, with a herd of approximately 210 million animals. For the meat industry, a reliable animal traceback from its origin to the consumer market is paramount. Of all available identification systems, DNA is the only one that survives the slaughterhouse and reaches the dish of the consumer. DNA polymorphisms are already used for cattle traceback ... more

Carcass composition trait; Cattle; Growth trait; Meat quality trait; Polymorphism; Thyroglobulin gene

Thyroid hormones play an important role in regulating metabolism and can affect metabolism-related traits such as fat deposition. The thyroglobulin (TG) gene produces the precursor of thyroid hormones and has been proposed as a candidate gene for a quantitative trait locus with an effect on fat deposition. In this study, we identified 4 novel single nucleotide polymorphisms (SNPs ... more

Cattle; Cross-reactivity; Cytokines; Goat; Human; Sheep

Eleven commercially available PE-labeled anti-human (IL-1-α, IL-6, IL-8, TNF-α, IL-17A, IL-5, IL-10, IL-12 and IL-13) and anti-mouse (IL-10, TNF-α) cytokine monoclonal antibodies (mAbs) were tested for cross-reactivity with cattle, goat, and sheep cytokines. Cross-reactivity was assessed by comparative analysis with the standard reactivity of the target species. Our data demonstrated ... more

AMPD1 gene; Cattle; Deletion mutation; Production traits

The objectives of the present study were to detect an 18-bp deletion mutation in the bovine adenosine monophosphate deaminase 1 (AMPD1) gene and analyze its effect on growth traits in 2 Chinese cattle breeds using DNA sequencing and agarose electrophoresis. The five 19-bp polymerase chain reaction products of the AMPD1 gene exhibited 3 genotypes and 2 alleles: WW: homozygote ... more

Adipose tissue; Buffalo; Cattle; Cell therapy; Mesenchymal stem cells

Adult stem cells are known for their plasticity and their potential to differentiate into several different cell types; these characteristics have implications for cell therapy and reproductive biotechnologies. In this study, we report on the isolation and characterization of mesenchymal stem cells (MSC) derived from bovine and buffalo adipose tissue. Cells isolated using enzymatic ... more

Bos taurus; Carcass traits; Chemerin gene; PCR-SSCP; SNP

Qinchuan is a red or yellow draft and beef breed in China. In order to identify a predictor of carcass traits on the basis of associations between carcass traits and gene polymorphism, variation in the bovine chemerin gene was investigated using PCR-single-strand conformational polymorphism and DNA sequencing. An SNP of A868G located in exon 2 of the Bos taurus chemerin gene was ... more
