  1. 16. Proteostasis and Aging in Saccharomyces cerevisiae - The role of a Peroxiredoxin

    Författare :Sarah Hanzén; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aging; Caloric restriction; Oxidative stress; Peroxiredoxins; Proteostasis; Protein aggregates; Ubiquitin-proteasome system;

    Sammanfattning : Aging is characterized by a progressive decline in physiological functions that limits biological processes, increases the risk of disease, and ultimately leads to death. At the cellular level, aging is associated with accumulation of damaged components, including proteins, indicating that protein homeostasis (or proteostasis) fails to maintain the integrity and functionality of the proteome as cells age.

  3. 17. Controlling protein homeostasis through regulation of Heat shock factor 1

    Författare :Anna E. Masser; Claes Andréasson; Marie Öhman; David Pincus; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; stress; protein homeostasis; molecular chaperones; heat shock response; Hsf1; Hsp70; Saccharomyces cerevisiae; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : In order to thrive in a changing environment all organisms need to ensure protein homeostasis (proteostasis). Proteostasis is ensured by the proteostasis system that monitors the folding status of the proteome and regulates cell physiology and gene expression to counteract any perturbations. LÄS MER

  4. 18. Roles of intermolecular interactions in amyloid fibril formation mechanisms

    Författare :Tony Werner; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; disulfide-bonds; Atox1; α-synuclein; Aggregation; protein interactions; Parkinson’s disease; β-parvalbumin; macromolecular crowding; osmolytes; Amyloid fibrils;

    Sammanfattning : Amyloid fibrils, a major pathological feature of several neurodegenerative disorders, are highly stable, insoluble aggregates of misfolded proteins. The formation of such aggregates involves a complex equilibrium between protein monomers, different on- and off-pathway transient oligomeric species, and amyloid fibrils. LÄS MER

  5. 19. β-N-methylamino-L-alanine (BMAA)-induced neurotoxicity : Studies in vitro and in vivo

    Författare :Lisa Ersson; Malin Andersson; Eva B Brittebo; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; BMAA; neurotoxin; neurodegeneration; cellular transport; metabolic profiling; protein-association; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : β-N-methylamino-L-alanine (BMAA) is a neurotoxic non-proteinogenic amino acid produced naturally by cyanobacteria, diatoms and dinoflagellates and it has been detected in samples from fresh and marine water from all over the world. It can bioaccumulate in fish and shellfish, and has a potential to biomagnify in a terrestrial food chain. LÄS MER

  7. 20. SOD, ORF and ALS: On the role of SOD1 and C9ORF72 in the pathogenesis of ALS

    Författare :Isil Keskin; Peter M. Andersen; Lars Lannfelt; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALS; SOD1; Misfolded species;

    Sammanfattning : Amyotrophic lateral sclerosis (ALS) is characterized by adult-onset degeneration of upper and lower motor neurons. Symptoms begin focally in one muscle and then spread contiguously, resulting in progressive paralysis and death from respiratory failure. LÄS MER
