The aim of this study was to find the optimal set of microsatellite markers for diagnosis of the microsatellite instability (MSI) phenotype in endometrial cancers. We compared the sensitivity, specificity and ease of use of a reference panel of five markers originally recommended by the National Cancer Institute (NCI) for colorectal cancer and a panel of five quasi-monomorphic mononucleotide re...

Microsatellite lengths change over evolutionary time through a process of replication slippage. A recently proposed model of this process holds that the expansionary tendencies of slippage mutation are balanced by point mutations breaking longer microsatellites into smaller units and that this process gives rise to the observed frequency distributions of uninterrupted microsatellite lengths. We...

PURPOSE Microsatellite instability (MSI) testing of colorectal cancer tumors is used as a screening tool to identify patients most likely to be mismatch repair (MMR) gene mutation carriers. We wanted to examine which microsatellite markers currently used to detect MSI best predict early-onset colorectal cancer caused by germ-line mutations in MMR genes. EXPERIMENTAL DESIGN Invasive primary tu...

In the last decade microsatellites have become one of the most useful genetic markers used in a large number of organisms due to their abundance and high level of polymorphism. Microsatellites have been used for individual identification, paternity tests, forensic studies and population genetics. Data on microsatellite abundance comes preferentially from microsatellite enriched libraries and DN...

Markers for eight new microsatellite DNA or simple sequence repeat (SSR) loci were developed and characterized in trembling aspen (Populus tremuloides) from a partial genomic library. Informativeness of these microsatellite DNA markers was examined by determining polymorphisms in 38 P. tremuloides individuals. Inheritance of selected markers was tested in progenies of controlled crosses. Six ch...

Microsatellites are simple sequence repeats with a high degree of polymorphism in the genome; they are used as DNA markers in many molecular genetic studies. Using traditional methods such as the magnetic beads enrichment method, only a few microsatellite markers have been isolated from the Chinese mitten crab Eriocheir sinensis, as the crab genome sequence information is unavailable. Here, we ...

Alterations in microsatellite sequences characterize hereditary nonpolyposis colorectal cancer. This microsatellite instability is due in some kindreds to a germline mutation of the mismatch repair gene hMSH2 on chromosome 2p. Although microsatellite alterations have been reported in other hereditary nonpolyposis colorectal cancer-associated tumors including endometrial and gastric cancers, suc...

Simple sequence repeat (SSR) or microsatellite markers, are a valuable tool for several purposes such as evaluation of genetic diversity, fingerprinting, marker assisted selection, and breeding. Recent developments in sequencing technologies and bioinformatics analyses provide new opportunity to produce a high number of less costly SSRs. Here, we used for the first time a wholegenome shotgun se...
