OBJECTIVE The enzyme heme oxygenase-1 (HO-1) exerts cytoprotective effects in response to various cellular stressors. A variable number tandem repeat polymorphism in the HO-1 gene promoter region has previously been linked to cardiovascular disease. We examined this association prospectively in the general population. APPROACH AND RESULTS Incidence of stroke, myocardial infarction, or vascula...
BACKGROUND Flavobacterium psychrophilum causes serious fish diseases such RTFS and BCWD, affecting the aquaculture industry worldwide. Commercial vaccines are not available and control of the disease depends on the use of antibiotics. Reliable methods for detection and identification of different isolates of this bacterium could play an important role in the development of good management strat...
An algorithm capable of identifying short repeat motifs was developed and used to screen the whole genome sequence available for Haemophilus influenzae, since some of these repeats have been shown to affect bacterial virulence. Various di- to hexanucleotide repeats were identified, confirming and extending previous findings on the existence of variable-number-of-tandem-repeat loci (VNTRs). Repe...
By conventional genetic methods, including pulse-field gel electrophoresis and multilocus sequence typing, most pathogenic, cholera toxin-positive O1 and O139 isolates of Vibrio cholerae cannot be distinguished. We evaluated relationships among 173 V. cholerae isolates collected between 1992 and 2007 from different geographic areas in India by analyzing five variable number of tandem repeat (VN...
This study shows for the first time that the tandemly repeated icosapeptide of human MUC1 underlies a genetic sequence polymorphism at three positions (underlined): PDTRPAPGSTAPPAHGVTSA. The concerted replacement DT-->ES (sequence variation 1) and the single replacements P-->Q (sequence variation 2), P-->A (sequence variation 3), and P-->T (sequence variation 4) were identified by sequencing of...
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...
