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
To investigate aberrant metabolism of proline (Pro) and its precursors in tuberous sclerosis (TS), 6, 7 and 5 strains of control, TS (normal skin) and TS (tumor) fibroblasts, respectively, were cultured in Eagle's MEM containing dialyzed fetal bovine serum with or without 0.1 mM ornithine (Orn).
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
Cultured skin fibroblasts from patients with tuberous sclerosis were analyzed as to their sensitivities to proline, glutamic acid and arginine, and their analogues by means of a cell growth study. A difference was observed between tuberous sclerosis and normal cells when proline was added. Skin
The serum levels of proline and hydroxyproline were determined by high-performance liquid chromatography using the post-labeled method with o-phthalaldehyde and sodium hypochlorite in 30 patients of tuberous sclerosis (TS) and compared with those in 32 pathological control subjects of similar age.
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
The misconstruction of proteins as a result of the displacement of one of more proline residues by their congener, azetidine-2-carboxylic acid (Aze), can result in various disorders. A number of lines of evidence suggest that multiple sclerosis may be among these. This concept adheres to the current
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
OBJECTIVE
We previously reported the presence of autoantibodies to the extracellular matrix protein, fibrillin 1, in sera from patients with systemic sclerosis (SSc). These autoantibodies appeared to be highly disease-specific but had significantly different frequencies among ethnic groups. The aims
Mitochondrial autoantibodies, a hallmark of primary biliary cirrhosis (PBC), have been widely described for many years in patients with systemic sclerosis, and there have been several reports of the concurrence of systemic sclerosis and PBC. However, there is very little information with respect to
Among the candidate genes for multiple sclerosis (MS), the strongest influence is conferred by human leucocyte antigen (HLA) class II genes, in particular the DR2, DQ6, Dw2 haplotype (DRB1*1501, DQA1*0102, DQB1*0602). Similar to other autoimmune diseases, it is not clear yet how the presence of 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
