1. 1. Genetic diversity of the heat labile (LT) and heat stable (ST) toxins of human enterotoxigenic Escherichia coli (ETEC): New insights into polymorphism, regulation, and gene transcription

   Författare :Enrique Joffre; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ETEC; diversity; bacterial enterotoxins; polymorphism; gene regulation; gene transcription; Diarrhoeal disease; bacterial infection;

   Sammanfattning : Infection with enterotoxigenic Escherichia coli (ETEC) is a leading cause of diarrhea in children in developing countries and travelers to endemic regions. ETEC is a diverse pathogen, with a wide range of virulence factors including enterotoxins and more than 25 identified colonization factors (CFs). LÄS MER

3. 2. Organization and regulation of mitochondrial gene expression

   Författare :Roger Salvatori; Martin Ott; Benoit Kornmann; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mitochondria; mitochondrial gene expression; post-transcriptional regulation; mitochondrial ribosome; protein-protein proximity; BioID; feedback loop; Biochemistry; biokemi;

   Sammanfattning : Mitochondria possess their own genome, remnant of the ancestral eubacterial endosymbiont DNA. This mitochondrial genome encodes mostly few key subunits of the respiratory chain. In order to synthesize these few proteins, mitochondria contain a complete gene expression machinery. LÄS MER

4. 3. The mitoribosome as a hub for integrating mitochondrial gene expression : Regulation of translation and early assembly of cytochrome b

   Författare :Andreas Carlström; Martin Ott; Chris Meisinger; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mitochondria; gene expression; mitochondrial ribosome; translation regulation; feedback loop; biokemi; Biochemistry;

   Sammanfattning : The mitochondrial proteome is a mosaic of proteins from two different genetic systems. The majority of mitochondrial proteins are encoded in the nuclear genome and are synthesized in the cytosol before imported to mitochondria. LÄS MER

5. 4. Bacterial gene expression inhibition with antisense peptide nucleic acids

   Författare :Rikard Dryselius; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Regulated gene expression is widely useful for gene function studies and as a means to control genes important in disease. There are many methods for regulating the expression of genes, and one approach is to use antisense oligonucleotides that bind complementary mRNAs to inhibit translation. LÄS MER

7. 5. A Unified Multitude : Experimental Studies of Bacterial Chromosome Organization

   Författare :Eva Garmendia; Diarmaid Hughes; Linus Sandegren; John R. Roth; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bacterial evolution; chromosome organization and structure; chromosomal inversions; EF-Tu; horizontal gene transfer; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

   Sammanfattning : Bacteria are many, old and varied; different bacterial species have been evolving for millions of years and show many disparate life-styles and types of metabolism. Nevertheless, some of the characteristics regarding how bacteria organize their chromosomes are relatively conserved, suggesting that they might be both ancient and important, and that selective pressures inhibit their modification.
