Microsatellites are widely used as genetic markers because they are co-dominant, multiallelic, easily scored and highly polymorphic. A major drawback of microsatellite markers is the time and cost required to characterise them. We have developed a novel technique to reduce this cost by producing a microsatellite-rich PCR profile from genomic DNA which was cloned to yield a genomic library enric...

UNLABELLED PREMISE OF THE STUDY Microsatellite loci were developed to characterize genetic variation and population subdivision in Khaya senegalensis (Desr.) A. Juss. (Meliaceae). • METHODS AND RESULTS Microsatellite loci were identified from genomic DNA sequences generated using the 454 GS-FLX titanium platform. Primers were designed for 67 tri- and tetranucleotide repeats, of which 20 we...

Microsatellite discovery from genomic libraries is tedious because of the low number of clones that contain inserts and costly because of screening methodologies. A new procedure for screening clones for microsatellite DNA is described herein. Instead of colony hybridization, a polymerase chain reaction (PCR) with two vector standard primers and one synthesized repeat primer was used to directl...

The present study was undertaken to construct a multiplex microsatellite panel for parentage testing in Mehsana buffalo (Bubalus bubalis). The study was based on a total of 212 Mehsana buffalos (100 dams, 100 daughters, and 12 sires). Genomic DNA was extracted from blood and semen samples. A panel of 10 microsatellite markers (CSSM61, ILSTS29, ILSTS17, ILSTS28, CSSM57, CSSM22, ILSTS61, CSSM8, E...

Microsatellite instability (MSI) is a unique molecular abnormality, indicative of a deficient DNA mismatch repair (MMR) system. Described and characterized in the colorectal cancer literature, the MSI-positive phenotype is predictive of disease susceptibility, pathogenesis, and prognosis. The clinical relevance of MSI in colorectal cancer has inspired similar inquisition within the sarcoma lite...

Abstract On the basis of in situ analysis sturgeon condition within Lower Danube River, aim was to carry out a research that would complement results obtained from monitoring and ultrasonic tagging methods. Thus, DNA samples were taken selectively each ultrasonically tagged specimen order determine whether or not there is possibility hybridization between species Acipenser stellatus Huso huso ....

DNA hypomethylation is frequently seen in cancer and imparts genomic instability in mouse models and some tissue culture systems. However, the effects of genomic DNA hypomethylation on mutation rates are still elusive. We have developed a model system to analyze the effects of DNA methyltransferase 1 (Dnmt1) deficiency on DNA mismatch repair (MMR) in mouse embryonic stem (ES) cells. We generate...

Cells proliferating from human atherosclerotic lesions are resistant to the antiproliferative effect of TGF-beta1, a key factor in wound repair. DNA from human atherosclerotic and restenotic lesions was used to test the hypothesis that microsatellite instability leads to specific loss of the Type II receptor for TGF-beta1 (TbetaR-II), causing acquired resistance to TGF-beta1. High fidelity PCR ...

BACKGROUND Microsatellites or simple sequence repeats (SSRs) are highly informative molecular markers for various biological studies in plants. In spruce (Picea) and other conifers, the development of single-copy polymorphic genomic microsatellite markers is quite difficult, owing primarily to the large genome size and predominance of repetitive DNA sequences throughout the genome. We have deve...

The molecular biology section of the Hereditary Non-Polyposis Colorectal Cancer study group-Germany, instituted a multicenter study to test the reliability and quality of microsatellite instability (MSI) analysis. Eight laboratories compared MSI analyses performed on 10 matched pairs of normal and tumor DNA from patients with colorectal carcinomas. A variety of techniques were applied to the de...
