  2. 1. Structural investigation of SOD1 aggregates in ALS : identification of prion strains using anti-peptide antibodies

    Author : Johan Bergh; Thomas Brännström; Stefan L. Marklund; Peter M. Andersen; Joakim Bergström; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALS; SOD1; prion; motor neuron disease; neurodegeneration; strain; seeding; protein aggregation; transgenic mice; peptide antibodies; Neurology; neurologi;

    Abstract : Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative syndrome characterized by progressive degeneration of motor neurons that result in muscle wasting. The symptoms advance gradually to paralysis and eventually death. Most patients suffer from sporadic ALS (sALS) but 10% report a familial predisposition. READ MORE

  4. 2. Oxidants and antioxidants in cardiovascular disease

    Author : Kim Ekblom; Johan Hultdin; Stefan L Marklund; Lars Breimer; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; first-ever acute myocardial infarction; first-ever stroke; bilirubin; iron; HFE genotypes; UGT1A1*28; prospective; risk factor; Cardiovascular medicine; Kardiovaskulär medicin; Epidemiology; Epidemiologi; Clinical Chemistry; klinisk kemi;

    Abstract : Background Cardiovascular diseases, including myocardial infarction and stroke, are the main reason of death in Sweden and Western Europe. High iron stores are believed to produce oxygen radicals, which is the presumed putative mechanism behind lipid peroxidation, atherosclerosis and subsequent cardiovascular disease. READ MORE

  5. 3. SOD1 prions transmit templated aggregation and fatal ALS-like disease

    Author : Elaheh Ekhtiari Bidhendi; Thomas Brännström; Stefan L. Marklund; Peter M. Andersen; Inger Nennesmo; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALS; amyotrophic lateral sclerosis; SOD1; prion; neurodegeneration; strain; seeding; protein misfolding; protein aggregation; propagation; transgenic mice; Pathology; patologi; Neurology; neurologi;

    Abstract : Amyotrophic lateral sclerosis (ALS) is an adult-onset fatal neurodegenerative disease characterized by a progressive degeneration of the upper and lower motor neurons. The resulting paresis begins focally, usually in one muscle, and spreads contiguously, leading to muscle wasting, progressive paralysis and eventually death. READ MORE

  6. 4. Superoxide dismutase 1 and amyotrophic lateral sclerosis

    Author : P. Andreas Jonsson; Stefan L. Marklund; David R. Borchelt; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; aggregates; ALS; amyotrophic lateral sclerosis; cerebrospinal fluid; disulfide-reduced; inclusions; misfolded; protective factor; SOD1; transgenic; Neurovetenskap; Neurology; Neurologi; Clinical Chemistry; klinisk kemi;

    Abstract : Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting motor neurons in the spinal cord, brain stem and motor cortex, leading to paralysis, respiratory failure and death. In about 5% of ALS cases, the disease is associated with mutations in the CuZn-superoxide dismutase (hSOD1) gene. READ MORE

  7. 5. SOD1 misfolding and aggregation in ALS : in the light of conformation-specific antibodies

    Author : Manuela Lehmann; Jonathan D. Gilthorpe; Stefan L. Marklund; Thomas Brännström; Ulrika Nordström; Elizabeth Fisher; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALS; antibodies; SOD1; disordered SOD1; patient-derived models; low oxygen tension; Immunotherapy;

    Abstract : Mutations in the superoxide dismutase 1 (SOD1) gene are linked to the progressive neurodegenerative disease amyotrophic lateral sclerosis (ALS). ALS-associated mutations affect the stability of the SOD1 protein and promote its unfolding. As a consequence, disordered SOD1 species can misfold and accumulate into insoluble aggregates. READ MORE
