Animal Genetics
Computing numerator relationships between any pair of animals
Authors: L.D. Van Vleck
We describe a simple method to compute the numerator relationship between any or all pairs of animals in the numerator relationship matrix. The method depends on output of the MTDFNRM program from the MTDFREML set of programs. An option of the MTDFNRM program creates a file that includes the inbreeding coefficient for each ani..

Polymorphisms of AluI and Hin1I loci of the IGF-1R gene and their genetic effects on growth traits in Bian chickens
Authors: P.F. Wu, D. Wang, C.F. Jin, X.Q. Zhang, H.Q. Wu, L. Zhang, F.X. Ding, K. Z. Xie and G.X. Zhang
Growth traits are important economic traits in broiler chicken production. AluI and Hin1I loci are two restriction sites, which are respectively located in exons 2 and 3 of the IGF-1R gene. These two loci are significantly related to the growth traits in Jinghai Yellow chickens. In this study, a correlation analysis was perfor.. Read More»

Study of different structures of additive genetic groups to increase the efficiency of genetic selection in beef cattle
Authors: G.A. Oliveira Junior
The structure of genetic groups is a technique that allows animals with unknown paternity to be included in genetic evaluation programs. The ways these groups are formed are still arbitrary, making it important to study different formation strategies for genetic groups, aiming for a suitable framework for the genetic evaluatio..

Acute heat stress and dietary methionine effects on IGF-I, GHR, and UCP mRNA expression in liver and muscle of quails
Authors: A.P. Del Vesco, E. Gasparino, V. Zancanela, D.O. Grieser, S.E.F. Guimar�£es, C.S. Nascimento, D.M. Voltolini, J. Constantin and F.S. Gasparin
This study evaluated the expression of insulin-like growth factor I (IGF-I), growth hormone receptor (GHR), and uncoupling protein (UCP) mRNA in muscle and liver of quails that were in thermal comfort or exposed to heat stress and that were fed diets with or without methionine supplementation. Meat quails were fed a diet that .. Read More»

Tissue- and breed-specific expression of the chicken fat mass- and obesity-associated gene (FTO)
Authors: C. Song, W.T. Song, J.T. Shu, Z.Y. Tao, W.Q. Zhu, C. Di and H.F. Li
The fat mass- and obesity-associated gene (FTO) is involved in energy metabolism, but little is known about the chicken FTO gene. The objective of the current study was to detect chicken FTO expression patterns in the hypothalamus, liver, and skeletal muscle during development, and analyze the effects of age and breed on FTO expression. Real-time quantita.. Read More»

Evaluation of Hsp47 expression in heat-stressed rat myocardial cells in vitro and in vivo
Authors: A. Abdelnasir1,2, J.R. Sun1, Y.F. Cheng1, H.B. Chen1, S. Tang1, N. Kemper3, J. Hartung3 and E.D. Bao1
The aim of the present study was to identify the correlation between expression of heat shock protein 47 (Hsp47) and stress injury in heat-stressed myocardial cells and to compare variations in Hsp47 expression in rat myocardial cells exposed to different heat stress for varying periods in vitro and in vivo. Exposure to heat stress at 42°C resulted in.. Read More»

Genetic features of a translation initiation system composed of IRES element, nucleotide context surrounding the initiation codon, and translation initiation region of classical swine fever virus RNA
Authors: X.-X. Ma*, Y.-P. Feng*, Y.-Q. Zhao, J.-L. Liu, L. Chen, P.-H. Guo, J.-Z. Guo, L.-Y. Ma and Z.-R. Ma
Nucleotide and codon usage are typically examined to investigate viral evolution. In this study, we analyzed the genetic information of 46 strains of classical swine fever virus (CSFV) RNA, nucleotide usage in the internal ribosome entry site (IRES), the nucleotide context surrounding the initiation codon, and synonymous codon usage in the translation ini..

Molecular cloning, expression, and regulation of the ovalbumin gene in pigeon oviduct epithelial cells
Authors: H. Zhang, L.Z. Lu, L. Chen, Z.R. Tao, F. Chen, S.L. Zhong,Y.L. Liu, Y. Tian and P.S. Yan
The full-length pigeon ovalbumin (OVA) gene cDNA was cloned and sequenced by reverse transcription-polymerase chain reaction (RT-PCR) and rapid-amplification of cDNA ends. A 386-amino acid protein was predicted for the obtained sequence, which had 67% identity with the chicken protein. Similar to chicken OVA, the pigeon OVA ge.. Read More»

DNA extraction from bristles and quills of Chaetomys subspinosus (Rodentia: Erethizontidae) using a novel protocol
Authors: C.G. Oliveira, R.A. Martinez, F.A. Gaiotto
DNA extraction protocols are as varied as DNA sources. When it comes to endangered species, it is especially important to pay attention to all details that ensure the completion of the study goals and effectiveness in attaining useful data for conservation. Chaetomys subspinosus (Rodentia: Erethizontidae) is a secretive arbore.. Read More»

Genetic diversity based on SSR analysis of the cultured snakehead fish, Channa argus, (Channidae) in China
Authors: S.-R. Zhu, J.-L. Li, N. Xie, L.-M. Zhu, Q. Wang and G.-H. Yue
The snakehead fish Channa argus is an important food fish in China. We identified six microsatellite loci for C. argus. These six microsatellite loci and four other microsatellite markers were used to analyze genetic diversity in four cultured populations of C. argus (SD, JX, HN, and ZJ) and determin.. Read More»
