Download or read book Stress Induced Mutagenesis written by David Mittelman and published by Springer Science & Business Media. This book was released on 2013-03-12 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of stress-induced mutagenesis has changed ideas about mutation and evolution, and revealed mutagenic programs that differ from standard spontaneous mutagenesis in rapidly proliferating cells. The stress-induced mutations occur during growth-limiting stress, and can include adaptive mutations that allow growth in the otherwise growth-limiting environment. The stress responses increase mutagenesis specifically when cells are maladapted to their environments, i.e. are stressed, potentially accelerating evolution then. The mutation mechanism also includes temporary suspension of post-synthesis mismatch repair, resembling mutagenesis characteristic of some cancers. Stress-induced mutation mechanisms may provide important models for genome instability underlying some cancers and genetic diseases, resistance to chemotherapeutic and antibiotic drugs, pathogenicity of microbes, and many other important evolutionary processes. This book covers pathways of stress-induced mutagenesis in all systems. The principle focus is mammalian systems, but much of what is known of these pathways comes from non-mammalian systems.

This book was released on 2006 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strain SM6716 is a division mutant of Escherichia coli with a temperature- sensi tive phenotype and previously isolated using P1-mediated hydroxylamine mutagenes is. Strain SM6716 was suspected to carry a mutation in the essential cell divisi on gene ftsN. However, transformation with plasmids carrying wild-type ftsN fail ed to complement the mutation, and chromosomal mapping by P1-transduction showed that the mutation is located in 89-90 minute region on the chromosome of E. col i. Using a pBR325-based plasmid library of HindIII-generated fragments of the E. coli genome, we obtained a clone with a ̃10Kbp HindIII fragment that was able t o complement the temperature-sensitive mutation in SM6716. Further restriction a nd deletion analysis of the complementing plasmid (pR10) demonstrated that the c o-overexpression of the rplL and rpoB genes, encoding the L7/L12 protein of the 50S subunit of the E. coli ribosome and the beta subunit of the RNA polymerase, respectively, was required for complementation. The results suggest strongly tha t the mutation responsible for the temperature-sensitive phenotype in strain SM6 716 resides in and affects expression from an upstream promoter (rplJp), resulti ng in under-expression of rplL and rpoB and leading to failure in cell division at 42 degrees C. Further characterization of the mutation in SM6716 should lead to the identification of the mutation site, and to proposing a mechanism by whi ch transcription, ribosomal function and cell division in Escherichia coli are r elated.

Book excerpt: Diploma Thesis from the year 2003 in the subject Biology - Micro- and Molecular Biology, grade: 1 (A), University of Innsbruck (Institute for Microbiology), language: English, abstract: In 1885 Theodor Escherich described the gram negative bacterium Escherichia coli (E. coli) (Escherich T., Rev.1989). The gram negative rod belongs to the family of the enterobacteriaceae. It is a natural inhabitant of the human and animal intestine. E. coli can also cause diseases like diarrhea, inflammation of the urinary tract or the gall bladder. Urinary tract infections (UTIs) are one of the most common reasons for antibiotic therapy worldwide (Burman and Olsson-Liljequist, 2001). People with UTIs suffer inflammation of the urinary tract, and frequently the kidneys. Two-thirds of patients with UTIs are women (Canbaz et al. 2002). This is related in part to the shortness of the urethra, which makes colonization of the bladder by bacteria more likely. The elderly and those who undergo genitourinary operations and catheterisation are also frequent sufferers of UTIs (Orenstein and Wong, 1999). The leading causative agent of UTIs is E. coli (60-80 %), usually originating from the patients own faecal flora, followed by Staphylococcus saprophyticus (10 %), Klebsiella sp., other Gram negative bacteria and enterococci (Burman and Olsson-Liljequist, 2001). The antibiotic class most frequently prescribed to treat UTIs in Western Europe and North America is the fluoroquinolones. Fluoroquinolones are synthetic antibiotics derived from nalidixic acid. Resistance to the synthetic fluoroquinolone antibiotics is increasing among the organisms that cause UTIs.
