These data suggest that NFL mRNA reductions are common to SALS and FALS patients, and that cells and mice expressing mutant SOD1 may enable us to characterize the molecular mechanism(s) responsible for the loss of neurofilament mRNA.
SOD-1 associated FALS mutants may have an altered radiation response due to an enhanced generation of hydroxyl radicals or a compromised ability to neutralize free radicals.
Overexpression of metallothionein-I, a copper-regulating protein, attenuates intracellular copper dyshomeostasis and extends lifespan in a mouse model of amyotrophic lateral sclerosis caused by mutant superoxide dismutase-1.
Autosomal-dominant familial amyotrophic lateral sclerosis (FALS) is associated with mutation in the gene that encodes Cu/Zn superoxide dismutase (SOD1).
Injury to motor neurons associated with mutant Cu,Zn-superoxide dismutase (SOD1)-related familial amyotrophic lateral sclerosis (FALS) results from a toxic gain-of-function of the enzyme.
We report a 54-year-old male with progressive and asymmetrical lower extremity weakness caused by familial amyotrophic lateral sclerosis (FALS) with a Cu/Zn superoxidase dismutase 1 (SOD1) gene mutation.
Circular dichroism measurements revealed that the FALS mutant SODs are sensitive to denaturation by dithiothreitol, SDS, or heat treatment, but these results do not completely explain the different recognition by the mAbs between wild-type and FALS mutant SODs under the denatured conditions.
In this study we have investigated the effects of over-expressing wild-type SOD1 and two mutant forms of SOD1 found in FALS, G93A and G93R, on cell survival using stably transfected neuronal cells.
Familial amyotrophic lateral sclerosis (FALS) has been modeled in transgenic mice by introducing mutated versions of human genomic DNA encompassing the entire gene for Cu,Zn superoxide dismutase (SOD1).
A transgenic (Tg) mouse model of FALS containing 25 copies of the mutant human SOD1 gene demonstrates motor neuron pathology and progressive weakness similar to ALS patients, leading to death at approximately 130 days.
Familial amyotrophic lateral sclerosis (ALS) in Japan associated with H46R mutation in Cu/Zn superoxide dismutase gene: a possible new subtype of familial ALS.
Point mutations in the gene encoding copper-zinc superoxide dismutase (SOD1) impart a gain-of-function to this protein that underlies 20-25% of all familial amyotrophic lateral sclerosis (FALS) cases.
Familial amyotrophic lateral sclerosis with a novel Leu126Ser mutation in the copper/zinc superoxide dismutase gene showing mild clinical features and lewy body-like hyaline inclusions.
Clinical characteristics of familial amyotrophic lateral sclerosis (FALS) with four different missense point mutations in exons 2, 4, and 5 of the Cu/Zn superoxide dismutase (SOD) gene were reported.
