چکیده

QTL mapping: The AW33 QTL was shown to be linked to microsatellite MCW0170, and the ST53 QTL was tightly linked to MCW0114, both markers located on GGA4. Our results demonstrate that these markers and therefore the associated QTLs, map within the GGA4q21–q22 and GGA4q11–12 regions, respectively. These results provide multiple entry points into the physical map and sequence of the chicken genome for identification of genes that might underlie QTLs. For example, MCW0114 maps near IDS, the iduronate-2-sulfatase gene, whose product is involved in heparin sulphate metabolism, and MCW0170 maps to a region containing well-known regulatory genes (KIT, CLOCK, EGF and two GABA receptor genes) and UGDH, also involved in glycosaminoglycan and heparin sulphate metabolism. Variation in these genes could possibly affect egg size and/or shell characteristics.

I-49: Human Y Chromosome ProteomeProject

The success of the Human Genome Project (HGP) has provided a blueprint for the approximately 20,000 gene-encoded proteins potentially active in all of the hundreds of cell types that make up the human body. Yet we still have limited knowledge about a majority of the gene-encoded proteins which are the “building blocks of life” and “cellular machinery”. It is estimated that for nearly half of th...

Combination of Myelin Basic Protein Gene Polymorphisms with HLA-DRB1*1501 in Iranian Patients with Multiple Sclerosis

Background: Multiple sclerosis (MS), as a multifactorial autoimmune disease with complex genetic basis, causes demyelination in the central nervous system via cytokine responses to myelin antigens. Myelin basic protein (MBP) is the main protein component of the myelin sheath. HLA-DRB (human leukocyte antigen-DR beta) alleles, particularly HLA-DRB1*1501, may be of significance in the pathogenesi...

Rapid communication: genetic linkage and physical mapping of the porcine cholesteryl ester transfer protein (CETP) gene.

Source and Description of Primers. The conserved sequences of human and rabbit cholesteryl ester transfer protein gene (CETP) (GenBank accession numbers NM000078 and M27486, respectively) were used to design primers to PCR amplify porcine CETP. The primers amplified a 970-bp fragment of porcine CETP gene spanning an intron between exon 1 and exon 2. The porcine CETP sequence (GenBank accession ...

Radiation hybrid mapping of the porcine AMPD 1 , PKLR and CHRNB 2 genes to chromosome 4

ree porcine genes, AMPD1 (encoding muscle isoform of adenosine monophosphate deaminase), PKLR (encoding liver and red blood cell isozymes of pyruvate kinase) and CHRNB2 (encoding neuronal nicotinic acetylcholine receptor, beta 2 polypeptide), were assigned to the radiation hybrid map of chromosome 4 using PCR amplification on clones of the IMpRH panel. PKLR was mapped between markers SW270 and...
