OBJECTIVE
Cardiac ankyrin repeat protein, CARP, is a protein that is restrictedly expressed in the heart but barely expressed in skeletal muscles. Since CARP is induced by pressure overload to the heart, it is proposed to be a genetic marker for cardiac hypertrophy. We recently identified a novel
In spinal cords from seven amyotrophic lateral sclerosis (ALS) patients and four controls, we found no difference in thyrotropin-releasing hormone (TRH) concentration relative to protein content, but there was a reduction per tissue wet weight in ALS. Immunohistochemical localization of TRH in ALS
A human isoform of the vesicle-associated membrane protein-associated proteins (VAPs), VAPB, causes amyotrophic lateral sclerosis eight due to the missense mutation of Pro-56, whereas human VAPA and the yeast VAP Scs2p proteins are not significantly affected by similar mutations. We have found that
In amyotrophic lateral sclerosis (ALS), motor neuron degeneration is associated with systemic metabolic impairment. However, the evolution of metabolism alteration is partially unknown and its link with disease progression has never been described. For the first time, we ran a study focused on (1)
A mutation in the ubiquilin 2 gene (UBQLN2) was recently identified as a cause of X-linked amyotrophic lateral sclerosis (ALS)/frontotemporal dementia (FTD) and a major component of the inclusion bodies commonly found with a wide variety of ALS. ALS-linked mutations in UBQLN2 are clustered in a
Analysis of 226 exome-sequenced UK cases of familial amyotrophic lateral sclerosis (ALS) and frontotemporal dementia identified 2 individuals who harbored a P497H and P506S UBQLN2 mutation, respectively (n = 0.9%). The P506S index case presented with behavioral variant frontotemporal dementia at the
The histological identification of ubiquitin-conjugated protein deposits in spinal motor neurones of patients with amyotrophic lateral sclerosis (ALS) has suggested that an underlying abnormality of intracellular protein metabolism may be responsible for the pathogenesis of the disease. In an
Mutations in the UBQLN2 gene, which encodes a member of the ubiquitin-like protein family (ubiquilin-2), have been recently identified in patients with dominant X-linked amyotrophic lateral sclerosis (ALS) and ALS with dementia. We report here the sequencing of the UBQLN2 gene in 590 ALS patients of
Degeneration of cortical and spinal motor neurons is the typical feature of amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disease for which a pathogenetic role for the Cu/Zn superoxide dismutase (SOD1) has been demonstrated. Mice overexpressing a mutated form of the SOD1 gene
Aberrant accumulation of extensively phosphorylated heavy (high molecular weight) neurofilament (NFH) and neurodegeneration are features of hereditary canine spinal muscular atrophy (HCSMA), an animal model of human motor neuron disease. In this study, the canine NFH gene was mapped, cloned, and
We measured the levels of amino acids in biopsied skin from eight patients with amyotrophic lateral sclerosis (ALS) and seven controls. The most conspicuous changes in ALS patients were as follows. First, the contents of the acidic amino acids glutamate and aspartate were significantly decreased in
Little is known concerning the changes of amino acid composition in different regions of the spinal cord in patients with amyotrophic lateral sclerosis (ALS). We performed quantitative amino acid analyses in the posterior funiculus, the lateral corticospinal tract, and the anterior horn of cervical
Fused in sarcoma (FUS) gene encodes the RNA binding protein FUS. This gene is mapped to chromosome 16p11.2. The FUS protein binds with karyopherineβ2 (Kapβ2) through its proline/tyrosine nuclear localization signal (PY-NLS) that helps in the localization of FUS protein within the nucleus. Arginine
A novel heterozygous mutation, Pro525Arg (P525R) in the Fused in Sarcoma (FUS) protein is predominant in young adult females with familial amyotrophic lateral sclerosis (fALS). Investigation of the biophysical characteristics of this mutation through analysis of protein conformation could provide
