To determine the effect of environmental factors on the preservation of DNA, archeological teeth of approximately similar age but greatly differing site milieu were examined for DNA content. The complex relational system of locational milieu of the samples was reduced to its essential and, at the same time, easily measurable factors. These are temperature, humidity, pH value, the geochemical pr...
background and objectives: hereditary nonpolyposis colorectal cancer (hnpcc) is an autosomal dominant cancer predisposition syndrome caused by germ-line mutations in dna mismatch repair genes. tumors arising as a result of these mutations display instability in a sequence area known as microsatellites. studies have shown that some bethesda markers (bat25, bat26) are more efficient than others i...
A total of 65 blood samples collected from Holstein cattle were employed for DNA extraction. Genomic DNA were amplified by means of random amplified polymorphic DNA (RAPD). One hundred and one random primers (Operon kits OPAA, OPAO, OPAV, OPC, OPE and OPA-06) were used for polymerase chain reactions (PCR). The PCR products were size fractionated by means of electrophoresis in agarose gel, trans...
The patterns of mutation and evolution at 13 microsatellite loci were studied in the filamentous fungal genus Neurospora. First, a detailed investigation was performed on five microsatellite loci by sequencing each microsatellite, together with its nonrepetitive flanking regions, from a set of 147 individuals from eight species of Neurospora. To elucidate the genealogical relationships among mi...
We extended the concept of fluorescent microsatellite genotyping with a single-universal tailed primer to the simultaneous use of three different tailed primers to allow multiplexed 4-color detection for medium throughput genotyping of plant species. The method was tested on Eucalyptus DNA samples using three forward primer sequences of human microsatellite markers labeled with different fluore...
PREMISE OF THE STUDY Nonplastid microsatellite primers were developed for the first time in the Euro-Siberian complex of Anthoxanthum (Poaceae), a genus of temperate grasses in which reticulate evolution is common. METHODS AND RESULTS A microsatellite-enriched genomic DNA library allowed the detection of 500 fragments containing a microsatellite motif. Fifteen primer pairs were selected for a...
Genetic Comparison of Two Different Arabian Oryx Populations in UAE Based on Microsatellite Analysis
This is a genetic comparison study of Arabian Oryx (Oryx leucoryx) population at two different locations (A &B) based on nuclear microsatellite DNA markers. Arabian Oryx is listed as vulnerable and endanger by the World Conservation Union (IUCN). Thirty microsatellite markers from bovine family were applied to investigate the genetic diversity of the Arabian Oryx and to set up a molecular inven...
The microsatellite loci FCA045, FCA077, FCA008, and FCA096 are highly variable molecular markers which were used to determine the genetic diversity in 148 captive Leopardus sp. The PCR-amplified products of microsatellite loci were characterized in ABI Prism 310 Genetic Analyzer. Allele numbers, heterozygosity, polymorphism information content, exclusive allele number, and shared alleles were c...
DNA mismatch repair (MMR) function is critical for correcting errors coincident with polymerase-driven DNA replication, and its proteins are frequent targets for inactivation (germline or somatic), generating a hypermutable tumor that drives cancer progression. The biomarker for defective DNA MMR is microsatellite instability-high (MSI-H), observed in ~15% of colorectal cancers, and defined by ...
