objective ullrich congenital muscular dystrophy is a rather severe type of congenital muscular dystrophy with early onset features related to motor development. in general it is inherited in autosomal recessive principles, however in the western world mostly seen with de novo dominant mutations in the collagen vi genes. milder form of the condition is the bethlem myopathy. there may be overlap ...
Whole-genome DNA microarrays were used to examine the gene expression profile of Shewanella oneidensis MR-1 during U(VI) and Cr(VI) reduction. The same control, cells pregrown with nitrate and incubated with no electron acceptor, was used for the two time points considered and for both metals. U(VI)-reducing conditions resulted in the upregulation (> or = 3-fold) of 121 genes, while 83 genes we...
Chromium (VI) is a well-known pollutant that present in industrially polluted soil and water, has been reported to be mutagenic carcinogenic. In the study, we investigated effective use of Leptolyngbya boryana (cyanobacterium) as an eco-friendly option overcome Cr toxicity tannery effluents. The main objective this study was identify reductase (ChrR) gene its variability context stress. Industr...
conclusions this study detected multiple drug resistance (mdr) in p. aeruginosa including aminoglycosides. therefore, identification of drug resistance patterns in p. aeruginosa is of great importance in prevention and control of infections in burn patient centers. background the prevalence of resistance to aminoglycosides among p. aeruginosa isolates has increased all around the world. the res...
Chromium (Cr) (VI) is a major environmental toxic metal and a human carcinogen. The molecular events mediating cellular responses to Cr(VI) are not clear at present. We show that Cr(VI) potently induced apoptosis and production of reactive oxygen species (ROS) in mouse hepa1c1c7 cells in a concentration-dependent manner. Mouse embryonic fibroblast cells lacking Nrf2 exhibited elevated ROS produ...
Collagen VI myopathies are genetic disorders caused by mutations in collagen 6 A1, A2 and A3 genes, ranging from the severe Ullrich congenital muscular dystrophy to the milder Bethlem myopathy, which is recapitulated by collagen-VI-null (Col6a1(-/-)) mice. Abnormalities in mitochondria and autophagic pathway have been proposed as pathogenic causes of collagen VI myopathies, but the link between...
The Vi capsular polysaccharide (CPS) of Salmonella enterica serovar Typhi, the cause of human typhoid, is important for infectivity and virulence. The Vi biosynthetic machinery is encoded within the viaB locus composed of 10 genes involved in regulation of expression (tviA), polymer synthesis (tviB-tviE), and cell surface localization of the CPS (vexA-vexE). We cloned the viaB locus from S. Typ...
Recognition and response to non self is essential to development and survival of all organisms. It can occur between individuals of the same species or between different organisms. Fungi are established models for conspecific non self recognition in the form of vegetative incompatibility (VI), a genetically controlled process initiating a programmed cell death (PCD) leading to the rejection of ...
Previous studies have suggested that procollagen types I and III are the major collagenous gene products of cultured human skin fibroblasts. In this study the expression of 10 different genes, encoding the subunit polypeptides for collagen types I-VI, by human skin fibroblasts in culture was analyzed by molecular hybridizations. Northern transfer analysis demonstrated the presence of specific m...
