EcoRI polymorphism within the GLI gene (chromosome 12q13.3-14.1) Source/Description: pKK36Pl contains a 1.55 kb PstI genomic fragment of GLJ cloned into the PstI site of pGEM-3 (1). Polymorphism: EcoRI identifies a two allele polymorphism (Al: 18 kb; A2: 5 kb). Frequency: Estimated from 91 individuals. Al 18 kb (0.72) A2 5kb (0 28) Chromosomal Localisation: Assigned to chromosome 12ql3.3-14.1 u...

Total DNA isolated from Rhizobium leguminosarum VF39SM cells is resistant to cleavage by the restriction endonuclease PstI. Plasmid curing and transfer studies localized this phenotype to pRleVF39b, the second smallest of six plasmids found in this bacterium. In vitro selection for vector modi®cation was employed to isolate a presumptive methylase gene (M.Rle39BI) from a plasmid gene library. T...

Human cancer risk assessment using molecular genetic techniques is a rapidly emerging field. Many studies suggest that both inherited and acquired genetic predispositions play an important role in carcinogenesis. Cytochrome P450 (CYP) 2E1 is involved in the metabolic activation of N-nitrosamines and other low molecular weight compounds. A recently described genetic polymorphism of CYP2E1 [DraI ...

BACKGROUND AND OBJECTIVES Varicella-Zoster virus (VZV) is a human herpes virus that usually attacks young children and commonly causes chicken pox (Varicella). Following primary infection, a lifelong latent infection is established. The virus often reactivates during adulthood or senesces to cause shingles (Zoster). Little is known regarding the genotypes of Varicella in Kuwait. The aim of this...

We developed Diversity Array Technology (DArT) markers for application in genetic studies of Brassica napus and other Brassica species with A or C genomes. Genomic representation from 107 diverse genotypes of B. napus L. var. oleifera (rapeseed, AACC genomes) and B. rapa (AA genome) was used to develop a DArT array comprising 11 520 clones generated using PstI/BanII and PstI/BstN1 complexity re...

We report on further cases of high functioning fragile X males showing decreased expression of FMR1 protein, absence of detectable methylation at the EagI site in the FMR1 gene promoter, and highly unusual patterns of fragile X mutations defined as smear of expansions extending from premutation to full mutation range. Very diffuse and therefore not easily detectable patterns of full mutations w...

In Shigella flexneri and enteroinvasive Escherichia coli (EIEC) the expression of the virulence-plasmid(pINV)-carried potential pathogenesis-associated apy gene, which encodes apyrase (ATP diphosphohydrolase), is regulated by the same regulators that govern the expression of virulence genes. To understand the transcriptional organization of the apy gene, the authors sequenced an 8023 bp PstI fr...

The genome segment 7 of two Indian isolates of bluetongue virus (BTV) from Avikanagar (BTV-1-western India) and Hyderabad (BTV-Untyped Hyderabad-southern India) was amplified by RT-PCR using two sets of VP7 specific primers. A sequence of 1137 bp comprising the complete coding sequence of the VP7 gene from Avikanagar isolate and a 1154 bp full-length sequence from BTV-UT Hyderabad isolate were ...

BACKGROUND To determine the relationship between DNA polymorphisms in the angiotensin I converting enzyme (ACE) gene, serum ACE activity and the risk of diabetic nephropathy. METHODS A case-control study was carried out in a population of Jewish insulin-dependent diabetes mellitus (IDDM) patients. Cases (77 IDDM patients with diabetic nephropathy) and controls (89 IDDM patients with normoalbu...

Proviral integration of a simian retrovirus highly homologous to human T-cell leukemia virus type I was examined in cellular DNAs extracted from primary peripheral blood lymphocytes of 31 adult African green monkeys (Cercopithecus aethiops) that were seropositive for simian T-cell leukemia virus type I (STLV-I). Among these monkeys, one case with overt leukemia, showing pleomorphic leukemia cel...
