Population genetic structure of Vimba vimba persa was investigated using microsatellite markers from 40 regions along the Iranian coastline of the Southern Caspian Sea (Anzali lagoon and Havigh River in Gilan province, BabolRoud River in Mazandaran province and GorganRoud River in Golestan province). Genomic DNA from 121 specimens was extracted from fin tissue by the Phenol-Chlorophor...

Deletions of DNA sequences on chromosome 3p [loss of heterozygosity (LOH)] are characteristic of clear cell renal carcinoma, which accounts for about 80% of all renal malignancies. Comparing tumor DNA to DNA from normal cells, LOH analysis of microsatellite sequences has aided in molecular diagnosis of renal carcinoma. Because clinically useful tumor markers do not exist for this cancer entity,...

Inactivation of the DNA mismatch repair pathway manifests as microsatellite instability, an accumulation of mutations that drives carcinogenesis. Here, we determined whether microsatellite instability in acute myeloid leukemia and myelodysplastic syndrome correlated with chromosomal instability and poly (ADP-ribose) polymerase (PARP) inhibitor sensitivity through disruption of DNA repair functi...

We have analyzed DNA obtained from 38 lung tumors and normal lung or blood DNA for microsatellite instability. Instability was examined at 10 different microsatellite loci on chromosome 3p, as well as loci on 3q, 11p, 11q, and 13q, and two on Xq. We observed microsatellite instability at one or more loci in 13 of the lung tumors analyzed, and this instability ranged from tumors showing instabil...

Altered microsatellite DNA in the blood of cancer patients may provide a novel means for tumor detection. Such alterations are a major characteristic of many types of tumor especially those associated with head or neck cancer. Moreover, recent evidence suggests that senescent tumor cells release DNA into the circulation, which is subsequently carried by the blood and thus enriched in the serum ...

Microsatellite alterations are a common feature of neoplastic cells. Our study aimed to compare the profile of microsatellite DNA alterations in tumor tissue and urine sediment at 12 selected microsatellite loci in transitional cell carcinoma of the bladder, and to determine which of the 12 markers or combination of markers has potential for the noninvasive diagnosis of bladder cancer. DNA alte...

objective(s): genetic analysis of two consanguineous pakistani families with localized autosomal recessive hypotrichosis was performed with the goal to establish genotype-phenotype correlation. materials and methods: genomic dna extraction had been done from peripheral blood samples. extracted dna was then subjected to pcr (polymerase chain reaction) for amplification. linkage analysis was perf...

Aberrant crypt foci (ACF) are distinct microscopic lesions of the colon thought to be the earliest identifiable precursors of colon cancer. As precursors of colon cancer, ACF may contain mutations in genes that are altered early in colorectal tumorigenesis. Candidates for these genes include APC, K-Ras, and those of the DNA mismatch repair system. Some colon cancers with mutations in DNA mismat...

Understanding the scale at which wild stocks of Persian sturgeon (Acipenser persicus) are genetically discrete is necessary for effective management of this commercially important species. Disomic DNA microsatellite markers are among the best tools for determining stock structure in fishes. As all sturgeon species have a polyploid ancestry of all sturgeons, most gene loci exhibit more than two ...
