Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease. An ALS drug, Riluzole, has been shown to induce two different anticancer effects on hepatocellular carcinoma (HCC). In light of this finding, we explore the relationship between ALS and cancer, especially for HCC, from the molecular biological viewpoint. We establish biomarkers that can discriminate between ALS patients a...

Amyotrophic lateral sclerosis (ALS), one of the most common adult-onset neurodegenerative diseases, has no known cure. Enhanced redox stress and inflammation have been associated with the pathoprogression of ALS through a poorly defined mechanism. Here we determined that dysregulated redox stress in ALS mice caused by NADPH oxidases Nox1 and Nox2 significantly influenced the progression of moto...

Amyotrophic lateral sclerosis (ALS) is a fatal degenerative disease of motor neurons. About 10 % of ALS cases are affected in a familial trait, a subset of which is caused by the mutation of Cu, Zn-superoxide dismutase (SOD1) gene (Rosen et al., 1993). Since the identification of the gene for familial ALS, research emphasis for ALS has been placed on uncovering the pathogenic mechanism of motor...

Little is known about global gene expression patterns in the human neurodegenerative disease amyotrophic lateral sclerosis (ALS). To address this, we used high-density oligonucleotide microarray technology to compare expression levels of approximately 6,800 genes in postmortem spinal cord gray matter obtained from individuals with ALS as well as normal individuals. Using Fisher discriminant ana...

INTRODUCTION Amyotrophic lateral sclerosis (ALS) is a devastating adult neurodegenerative disorder characterized by motor neuron degeneration and death around 3 years from onset. So far, riluzole is the only treatment available, although it only offers a slight increase in survival. The complex etiology of ALS, with several genes able to trigger the disease, makes its study difficult. AREAS C...

The ALS (agglutinin-like sequence) gene family of Candida albicans encodes cell-surface glycoproteins implicated in adhesion of the organism to host surfaces. Southern blot analysis with ALS-specific probes suggested the presence of ALS gene families in C. dubliniensis and C. tropicalis; three partial ALS genes were isolated from each organism. Northern blot analysis demonstrated that mechanism...

The branched-chain amino acids (BCAAs) valine, leucine and isoleucine are essential amino acids that are critical for animal growth and development. Animals need to obtain BCAAs from their diet because they cannot synthesize them. Plants are the ultimate source of these amino acids. Acetolactate synthase (ALS) is the first common enzyme in the biosynthesis of BCAAs. The metabolic control of BCA...

Mutations in the UBQLN2 gene, which encodes a member of the ubiquitin-like protein family (ubiquilin-2), have been identified in patients with dominant X-linked amyotrophic lateral sclerosis (ALS) and ALS with frontotemporal dementia (FTD). We analyzed mutations in the UBQLN2 gene in a Chinese cohort of 515 patients with sporadic ALS (sALS). A novel missense mutation (p.M392V) was detected in o...

Amyotrophic lateral sclerosis (ALS) is a fatal, progressive neurodegenerative disease that kills motor neurons. Despite a long disappointing history of human trials with neurotrophins, including insulin-like growth factor 1 (IGF-1), Kaspar and colleagues have successfully slowed disease in transgenic ALS mice by forcing motor neurons to produce IGF-1 following retrograde delivery of recombinant...

Amyotrophic lateral sclerosis (ALS) is a progressive, neurodegenerative disease characterized by loss of upper and lower motor neurons. ALS is considered to be a complex trait and genome-wide association studies (GWAS) have implicated a few susceptibility loci. However, many more causal loci remain to be discovered. Since it has been shown that genetic variants associated with complex traits ar...
