  1. 11. Interactions Between Small Heat Shock Proteins and Substrate Proteins Mass Spectrometric Detection of Crosslinked Peptides to Map Protein-Protein Interactions

    Författare :Emma Åhrman; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein-protein interactions; Small heat shock proteins; Mass spectrometric peptide mapping; Proteins; enzymology; Proteiner; enzymologi;

    Sammanfattning : The small heat shock proteins (sHsps) are a widespread class of molecular chaperones existing in all organisms. During heat stress the sHsps protect other proteins from unfolding and aggregation. In plants the sHsps play an especially prominent part of the stress response. LÄS MER

  2. 12. Intensive Care Unit Muscle Wasting : Skeletal Muscle Phenotype and Underlying Molecular Mechanisms

    Författare :Sudhakar Reddy Aare; Larsson Lars; Rooyackers Olav; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute quadriplegic myopathy; gene expression; myosin; heat shock proteins; mechanical ventilation; myostatin; sepsis; corticosteroids; diaphragm; Clinical Neurophysiology; Klinisk neurofysiologi;

    Sammanfattning : Acute quadriplegic myopathy (AQM), or critical illness myopathy, is a common debilitating acquired disorder in critically ill intensive care unit (ICU) patients characterized by generalized muscle wasting and weakness of limb and trunk muscles. A preferential loss of the thick filament protein myosin is considered pathognomonic of this disorder, but the myosin loss is observed relatively late during the disease progression. LÄS MER

  3. 13. Stress response regulation and protein aggregate inheritance in Caulobacter crescentus

    Författare :Frederic Dominique Schramm; Kristina Jonas; Franz Narberhaus; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stress; protein aggregation; cellular aging; molecular chaperones; heat shock response; DnaK; sigma factor; suppressor genes; DNA replication; starvation; Caulobacter crescentus; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Many stress conditions a cell encounters threaten the continuation of basic biological processes ultimately endangering its survival. Heat shock and antibiotic exposure can lead to a sudden surge of protein un- and misfolding, while nutrient starvation directly causes a lack of energy and molecular building blocks. LÄS MER

  4. 14. Molecular And Cellular Networks in Critical Illness Associated Muscle Weakness : Skeletal Muscle Proteostasis in the Intensive Care Unit

    Författare :Varuna Chaminda Banduseela; Lars Larsson; Gustavo Nader; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chaperones; autophagy; intensive care unit; heat shock proteins; protein synthesis; proteostasis; ER stress; gene expression; sepsis; neuromuscular blockers; corticosteroids; immobilisation; mechanical ventilation; Molekylär cellbiologi; Molecular Cellbiology; Molekylär medicin; Molecular Medicine;

    Sammanfattning : Critical illness associated muscle weakness and muscle dysfunction in intensive care unit (ICU) patients lead to severe morbidity and mortality as well as significant adverse effect on quality of life. Immobilization, mechanical ventilation, neuromuscular blocking agents, corticosteroids, and sepsis have been implicated as important risk factors, but the underlying molecular and cellular mechanisms remain unclear.

  5. 15. On chaperone co-operation in temporal and spatial protein quality control

    Författare :Rebecca Andersson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular chaperones; Heat shock proteins; Hsp70 chaperones; Proteostasis; Ageing; Asymmetric damage segregation; Peroxiredoxins; Spatial protein quality control;

    Sammanfattning : In order for a protein to be able to function correctly it needs to adopt its proper fold. Because of this, protein quality control (PQC) is vital at every level of cellular function. The central protein in PQC networks across all kingdoms of life are the Hsp70 molecular chaperones. LÄS MER
