Population genetic structure of North Atlantic killer whale samples was resolved from differences in allele frequencies of 17 microsatellite loci, mtDNA control region haplotype frequencies and for a subset of samples, using complete mitogenome sequences. Three significantly differentiated populations were identified. Differentiation based on microsatellite allele frequencies was greater betwee...
The neuropeptide vasopressin and its receptor V1aR are broadly implicated in social behavior and play a central role in several key aspects of male mating tactics in voles. In the prairie vole, a microsatellite in the cis-regulatory region of the gene encoding V1aR (avpr1a) provides a potential genetic basis for individual variation in neural phenotype and behavior; recent studies found that al...
Microsatellite loci are usually considered to be neutral co-dominant and Mendelian markers. We undertook to study the inheritance of five microsatellite loci in the European Lyme disease vector, the tick Ixodes ricinus. Only two loci appeared fully Mendelian while the three others displayed non-Mendelian patterns that highly frequent null alleles could not fully explain. At one locus, IR27, som...
Despite the low incidence of microsatellite instability (MSI) in lymphoid malignant neoplasms, it has been reported that the CD5 promoter MSI was relatively frequent among B-cell chronic lymphoproliferative disorders. We studied the presence of MSI in the CD5 promoter in 134 cases of B-cell chronic lymphocytic leukemia (B-CLL) and 47 of mantle cell lymphoma (MCL) by comparing the pattern of mic...
Microsatellite markers are used for loss-of-heterozygosity, allelic imbalance and clonality analyses in cancers. Usually, tumor DNA is compared to corresponding normal DNA. However, normal DNA is not always available and can display aberrant allele ratios due to copy number variations in the genome. Moreover, stutter peaks may complicate the analysis. To use microsatellite markers for diagnosis...
Molecular markers were used to investigate the stock structure of Patagonian toothfi sh (Dissostichus eleginoides) in the West Indian Ocean sector of the Southern Ocean. Four collections of D. eleginoides from Kerguelen (n = 1), Crozet (n = 1) and Prince Edward and Marion (n = 2) Islands were typed using two fragments of mitochondrial DNA (mtDNA) and seven nuclear microsatellite loci. MtDNA hap...
Microsatellites are important tools for plant breeding, genetics, and evolution, but few studies have analyzed their mutation pattern in plants. In this study, we estimated the mutation rate for 142 microsatellite loci in maize (Zea mays subsp. mays) in two different experiments of mutation accumulation. The mutation rate per generation was estimated to be 7.7 x 10(-4) for microsatellites with ...
CONTEXT Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine that is released by macrophages and lymphocytes and plays an important pathogenetic role in acute pancreatitis. It is present in large amounts in the serum and ascitic fluid in rats with experimental pancreatitis and its levels are elevated in humans with pancreatitis. Polymorphisms associated with inflammatory j...
MHC class I chain related gene A (MICA) is located near the HLA-B gene on the short arm of human chromosome 6. In the transmembrane (TM) of region of MICA, there is a trinucleotide repeat (GCT/AGC) microsatellite polymorphism in exon 5. Five alleles with 4, 5, 6 and 9 repetitions or 5 repetitions with 1 additional nucleotide insertion (GGCT) are identified and they were named A4, A5, A5.1, A6, ...
