1. 31. Caulobacter crescentus folding machines at the interface of inheritance, cell division, and energy metabolism

   Författare :Kristen Schroeder; Kristina Jonas; Pierre Genevaux; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chaperones; DnaK; chaperonin; GroESL; protein quality control; protein folding; stress response; cellular aging; cell division; bacterial respiration; Caulobacter crescentus; molekylär biovetenskap; Molecular Bioscience;

   Sammanfattning : All living cells must perform essential biological processes while monitoring and responding to environmental cues. Bacteria are accessible experimental systems in which to study the function of conserved central processes. LÄS MER

3. 32. Cell-penetrating peptides : Uptake mechanism and the role of receptors

   Författare :Henrik Helmfors; Ülo Langel; Hanne Mørck Nielsen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Sammanfattning : Genes are the major regulators of biological processes in every living thing. Problems with gene regulation can cause serious problems for the organism; for example, most cancers have some kind of genetic component. Regulation of biological processes using oligonucleotides can potentially be a therapy for any ailment, not just cancer. LÄS MER

4. 33. Effects of reactive oxygen species on the cellular vacuolar apparatus

   Författare :Johann Zdolsek; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

   Sammanfattning : Reactive and potentially harmful oxygen species occur, and are continuously formed, in all cells of a living organism. Increased production of these metabolites are seen in a number of pathological states, for instance in inflammatory foci or during reoxygenation of ischemic tissue. LÄS MER

5. 34. Physiological roles of amyloid precursor protein in vivo - zebrafish as a model

   Författare :Jasmine Chebli; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amyloid-beta precursor protein; amyloid precursor protein-b; zebrafish; physiological functions; development; trigeminal ganglia; ependyma; cilia; proteomics; translational adaptation;

   Sammanfattning : Amyloid-beta precursor protein (APP) is an evolutionarily conserved transmembrane protein expressed in many different tissues. APP belongs to a gene family consisting of two other APP-like proteins (APLP1 and APLP2). LÄS MER

7. 35. Heterogeneity of human metabolism in health and disease: a modelling perspective

   Författare :Pouyan Ghaffari Nouran; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer metabolism; fatty acid metabolism; genome-scale metabolic models; community modeling; heterogeneity; lung cancer; amino acids metabolism; gut microbiome;

   Sammanfattning : Metabolism is broadly defined as the sum of biochemical reactions within cells that are involved in maintaining the living state of the organism. Profound importance of metabolism comes from the fact that it is the sole source of energy that allows life to resist to be degraded into entropy. LÄS MER
