The role of variable DNA tandem repeats in bacterial adaptation.
DNA tandem repeats (TRs), also designated as satellite DNA, are inter- or intragenic nucleotide sequences that are repeated two or more times in a head-to-tail manner. Because TR tracts are prone to strand-slippage replication and recombination events that cause the TR copy number to increase or decrease, loci containing TRs are hypermutable. An increasing number of examples illustrate that bac...
متن کاملShort Communication The HRAS1 Variable Number of Tandem Repeats and Risk of Breast Cancer
Rare alleles at the HRAS1 variable number of tandem repeats (VNTRs) locus have been implicated in breast cancer risk. We assessed the association of rare HRAS1 alleles and breast cancer in a case-control study nested within the Nurses’ Health Study cohort. Using PCRbased methods, 717 incident breast cancer cases and 798 controls were genotyped for the HRAS1 VNTRs. The prevalence of the rare all...
متن کاملCorrelation and Identification of Variable number of Tandem repeats of eNOS Gene in Coronary artery disease (CAD).
Endothelium-derived nitric oxide (NO) is synthesized from l-arginine by endothelial nitric oxide synthase (eNOS) encoded by the NOS3 gene on chromosome7. Since reduced NO synthesis has been implicated in the development of coronary atherosclerosis; polymorphisms of NOS gene might be associated with increased susceptibility to coronary artery disease (CAD). We therefore undertook this study to d...
متن کاملVariable number of tandem repeats in Salmonella enterica subsp. enterica for typing purposes.
The genomic sequences of Salmonella enterica subsp. enterica strains CT18, Ty2 (serovar Typhi), and LT2 (serovar Typhimurium) were analyzed for potential variable number tandem repeats (VNTRs). A multiple-locus VNTR analysis (MLVA) of 99 strains of S. enterica supsp. enterica based on 10 VNTRs distinguished 52 genotypes and placed them into four groups. All strains tested were independent human...
متن کاملVariable-number tandem repeats as molecular markers for biotypes of Pasteuria ramosa in Daphnia spp.
Variable-number tandem repeats (VNTRs) have been identified in populations of Pasteuria ramosa, a castrating endobacterium of Daphnia species. The allelic polymorphisms at 14 loci in laboratory and geographically diverse soil samples showed that VNTRs may serve as biomarkers for the genetic characterization of P. ramosa isolates.
