Our group has developed more than 600 DNA markers to build a map of the canine genome. Of these markers, 125 correspond to
genes (anchor loci). Here we report the first six autosomal genes assigned to canine chromosomes by fluorescence in situ hybridization
(FISH), using cosmid DNA: adenine phosphoribosyl transferase on Chromosome (Chr) 3; creatine kinase muscle type on Chr 4;
pyruvate kinase liver and red blood cell type on Chr 2; and colony-stimulating factor-1 receptor, glucose transporter protein-2,
and tumor protein p53 on Chr 5. These assignments are based on the karytotype proposed by Stone and associates (Genome 34,
407, 1991) using high-resolution techniques. In addition, we have assigned the Menkes gene to the X Chr of the dog.

We have sought to determine the role of histone H2A phosphorylation in chromatin by examining the distribution of the phosphorylated and unphosphorylated forms of this core histone within the nuclei of mouse and human cells. At any time, only about 15% of the H2A of whole chromatin is in the phosphorylated form, and its phosphate is rapidly turned over, even in quiescent cells that contain a functional nucleus. The phosphorylations and dephosphorylations are not specifically relate to progress through the cell cycle, nor to DNA synthesis or repair, and they are not selectively nucleolar. Euchromatin is substantially enriched with phosphorylated H2A but is not the exclusive repository of it. Possible roles of this modification of H2A are considered. 相似文献

Degenerative myelopathy is a severe and progressive neurodegenerative disease and, in the majority of breeds, is associated with the c.118G>A substitution in exon 2 of the canine superoxide dismutase 1 (SOD1) gene. Our laboratories have been engaged in determining the cause of many discordant findings between the parental and the offspring genotypes found by different laboratories. In both cases, the discordant findings refer to actual heterozygous dogs that had been typed as homozygous for the variant allele. To that aim, the genomic context of the causative variant was investigated in two Hovawart dogs. An insertion of 54 nucleotides composed of a poly‐T stretch and 15 nucleotides containing the duplication of the exon 2–intron 2 junction was found. The insertion was responsible for the partial mismatch of the reverse primer used for a direct sequencing assay. The mismatch hampered the amplification of the corresponding allele and caused an evident drop‐out effect. The insertion is in complete linkage disequilibrium with the c.118G allele. The allele containing the insertion was highly prevalent in Hovawart dogs, accounting for the 26.6% of allele frequency. The insertion was also found in other unrelated breeds such as Rough Collies and Standard Poodles. In conclusion, the study illustrates the importance of correctly designing the primers to avoid inaccurate genotyping of the degenerative myelopathy causative variant in exon 2 of the SOD1 gene. 相似文献
