Gangliosidoses
A group of autosomal recessive lysosomal storage disorders marked by the accumulation of GANGLIOSIDES. They are caused by impaired enzymes or defective cofactors required for normal ganglioside degradation in the LYSOSOMES. Gangliosidoses are classified by the specific ganglioside accumulated in the defective degradation pathway.
Lipidoses
Conditions characterized by abnormal lipid deposition due to disturbance in lipid metabolism, such as hereditary diseases involving lysosomal enzymes required for lipid breakdown. They are classified either by the enzyme defect or by the type of lipid involved.
Hexosaminidase A
A mammalian beta-hexosaminidase isoform that is a heteromeric protein comprized of both hexosaminidase alpha and hexosaminidase beta subunits. Deficiency of hexosaminidase A due to mutations in the gene encoding the hexosaminidase alpha subunit is a case of TAY-SACHS DISEASE. Deficiency of hexosaminidase A and HEXOSAMINIDASE B due to mutations in the gene encoding the hexosaminidase beta subunit is a case of SANDHOFF DISEASE.
Hexosaminidase B
A mammalian beta-hexosaminidase isoform that is comprized of hexosaminidase beta subunits. Deficiency of hexosaminidase B due to mutations in the gene encoding the hexosaminidase beta subunit is a case of SANDHOFF DISEASE.
Hexosaminidases
Enzymes that catalyze the hydrolysis of N-acylhexosamine residues in N-acylhexosamides. Hexosaminidases also act on GLUCOSIDES; GALACTOSIDES; and several OLIGOSACCHARIDES.
beta-N-Acetylhexosaminidases
A hexosaminidase specific for non-reducing N-acetyl-D-hexosamine residues in N-acetyl-beta-D-hexosaminides. It acts on GLUCOSIDES; GALACTOSIDES; and several OLIGOSACCHARIDES. Two specific mammalian isoenzymes of beta-N-acetylhexoaminidase are referred to as HEXOSAMINIDASE A and HEXOSAMINIDASE B. Deficiency of the type A isoenzyme causes TAY-SACHS DISEASE, while deficiency of both A and B isozymes causes SANDHOFF DISEASE. The enzyme has also been used as a tumor marker to distinguish between malignant and benign disease.
Tay-Sachs Disease
An autosomal recessive neurodegenerative disorder characterized by the onset in infancy of an exaggerated startle response, followed by paralysis, dementia, and blindness. It is caused by mutation in the alpha subunit of the HEXOSAMINIDASE A resulting in lipid-laden ganglion cells. It is also known as the B variant (with increased HEXOSAMINIDASE B but absence of hexosaminidase A) and is strongly associated with Ashkenazic Jewish ancestry.
G(M2) Ganglioside
A glycosphingolipid that accumulates due to a deficiency of hexosaminidase A or B (BETA-N-ACETYLHEXOSAMINIDASES), or GM2 activator protein, resulting in GANGLIOSIDOSES, heredity metabolic disorders that include TAY-SACHS DISEASE and SANDHOFF DISEASE.
Sandhoff Disease
An autosomal recessive neurodegenerative disorder characterized by an accumulation of G(M2) GANGLIOSIDE in neurons and other tissues. It is caused by mutation in the common beta subunit of HEXOSAMINIDASE A and HEXOSAMINIDASE B. Thus this disease is also known as the O variant since both hexosaminidase A and B are missing. Clinically, it is indistinguishable from TAY-SACHS DISEASE.
G(M2) Activator Protein

Established cell cultures that have the potential to propagate indefinitely.
Lysosomes
A class of morphologically heterogeneous cytoplasmic particles in animal and plant tissues characterized by their content of hydrolytic enzymes and the structure-linked latency of these enzymes. The intracellular functions of lysosomes depend on their lytic potential. The single unit membrane of the lysosome acts as a barrier between the enzymes enclosed in the lysosome and the external substrate. The activity of the enzymes contained in lysosomes is limited or nil unless the vesicle in which they are enclosed is ruptured. Such rupture is supposed to be under metabolic (hormonal) control.

RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Electrophoresis, Polyacrylamide Gel
Electrophoresis in which a polyacrylamide gel is used as the diffusion medium.

Integrin alpha5beta1
An integrin found in FIBROBLASTS; PLATELETS; MONOCYTES, and LYMPHOCYTES. Integrin alpha5beta1 is the classical receptor for FIBRONECTIN, but it also functions as a receptor for LAMININ and several other EXTRACELLULAR MATRIX PROTEINS.
Integrin beta4
Also known as CD104 antigen, this protein is distinguished from other beta integrins by its relatively long cytoplasmic domain (approximately 1000 amino acids vs. approximately 50). Five alternatively spliced isoforms have been described.
Integrin beta Chains
Integrin beta chains combine with integrin alpha chains to form heterodimeric cell surface receptors. Integrins have traditionally been classified into functional groups based on the identity of one of three beta chains present in the heterodimer. The beta chain is necessary and sufficient for integrin-dependent signaling. Its short cytoplasmic tail contains sequences critical for inside-out signaling.

Biochemical consequences of mutations causing the GM2 gangliosidoses. (1/11)

The hydrolysis of GM2-ganglioside is unusual in its requirements for the correct synthesis, processing, and ultimate combination of three gene products. Whereas two of these proteins are the alpha- (HEXA gene) and beta- (HEXB) subunits of beta-hexosaminidase A, the third is a small glycolipid transport protein, the GM2 activator protein (GM2A), which acts as a substrate specific co-factor for the enzyme. A deficiency of any one of these proteins leads to storage of the ganglioside, primarily in the lysosomes of neuronal cells, and one of the three forms of GM2-gangliosidosis, Tay-Sachs disease, Sandhoff disease or the AB-variant form. Studies of the biochemical impact of naturally occurring mutations associated with the GM2 gangliosidoses on mRNA splicing and stability, and on the intracellular transport and stability of the affected protein have provided some general insights into these complex cellular mechanisms. However, such studies have revealed little in the way of structure-function information on the proteins. It appears that the detrimental effect of most mutations is not specifically on functional elements of the protein, but rather on the proteins' overall folding and/or intracellular transport. The few exceptions to this generalization are missense mutations at two codons in HEXA, causing the unique biochemical phenotype known as the B1-variant, and one codon in both the HEXB and GM2A genes. Biochemical characterization of these mutations has led to the localization of functional residues and/or domains within each of the encoded proteins.  (+info)

DRG-targeted helper-dependent adenoviruses mediate selective gene delivery for therapeutic rescue of sensory neuronopathies in mice. (4/11)

Dorsal root ganglion (DRG) neuron dysfunction occurs in a variety of sensory neuronopathies for which there are currently no satisfactory treatments. Here we describe the development of a strategy to target therapeutic genes to DRG neurons for the treatment of these disorders. We genetically modified an adenovirus (Ad) to generate a helper virus (HV) that was detargeted for native adenoviral tropism and contained DRG homing peptides in the adenoviral capsid fiber protein; we used this HV to generate DRG-targeted helper-dependent Ad (HDAd). In mice, intrathecal injection of this HDAd produced a 100-fold higher transduction of DRG neurons and a markedly attenuated inflammatory response compared with unmodified HDAd. We also injected HDAd encoding the beta subunit of beta-hexosaminidase (Hexb) into Hexb-deficient mice, a model of the neuronopathy Sandhoff disease. Delivery of the DRG-targeted HDAd reinstated neuron-specific Hexb production, reversed gangliosidosis, and ameliorated peripheral sensory dysfunction. The development of DRG neuron-targeted HDAd with proven efficacy in a preclinical model may have implications for the treatment of sensory neuronopathies of diverse etiologies.  (+info)

Kinesin Mutations Cause Motor Neuron Disease Phenotypes by Disrupting Fast Axonal Transport in Drosophila | GeneticsKinesin Mutations Cause Motor Neuron Disease Phenotypes by Disrupting Fast Axonal Transport in Drosophila | Genetics
Previous work has shown that mutation of the gene that encodes the microtubule motor subunit kinesin heavy chain (Khc) in Drosophila inhibits neuronal sodium channel activity, action potentials and neurotransmitter secretion. These physiological defects cause progressive distal paralysis in larvae. To identify the cellular defects that cause these phenotypes, larval nerves were studied by light and electron microscopy. The axons of Khc mutants develop dramatic focal swellings along their lengths. The swellings are packed with fast axonal transport cargoes including vesicles, synaptic membrane proteins, mitochondria and prelysosomal organelles, but not with slow axonal transport cargoes such as cytoskeletal elements. Khc mutations also impair the development of larval motor axon terminals, causing dystrophic morphology and marked reductions in synaptic bouton numbers. These observations suggest that as the concentration of maternally provided wild-type KHC decreases, axonal organelles transported ...

Mutant HSPB8 causes motor neuron-specific neurite degeneration : Human Molecular Genetics - oiMutant HSPB8 causes motor neuron-specific neurite degeneration : Human Molecular Genetics - oi
Missense mutations (K141N and K141E) in the α-crystallin domain of the small heat shock protein HSPB8 (HSP22) cause distal hereditary motor neuropathy (distal HMN) or Charcot-Marie-Tooth neuropathy type 2L (CMT2L). The mechanism through which mutant HSPB8 leads to a specific motor neuron disease phenotype is currently unknown. To address this question, we compared the effect of mutant HSPB8 in primary neuronal and glial cell cultures. In motor neurons, expression of both HSPB8 K141N and K141E mutations clearly resulted in neurite degeneration, as manifested by a reduction in number of neurites per cell, as well as in a reduction in average length of the neurites. Furthermore, expression of the K141E (and to a lesser extent, K141N) mutation also induced spheroids in the neurites. We did not detect any signs of apoptosis in motor neurons, showing that mutant HSPB8 resulted in neurite degeneration without inducing neuronal death. While overt in motor neurons, these phenotypes were only very mildly ...

The infantile and juvenile forms of GM1 and GM2 gangliosidoses are neurodegenerative conditions that are lethal during childhood. There are no known effective therapies available for treatment of infantile and juvenile gangliosidoses. Studies of monotherapy with miglustat for treatment of these conditions have demonstrated safety, but have not demonstrated notable clinical improvement. To date, combination therapy for the infantile and juvenile gangliosidoses has not been explored. This study will evaluate a multi-targeted combination therapy for treatment of the gangliosidoses, using FDA approved therapies that have demonstrated safety in children. It is the aim of this study to learn if combination therapy using the Syner-G regimen (that is, synergistic enteral regimen for treatment of the gangliosidoses) will show improvement in overall survival and clinical benefits in neurodevelopmental abilities in children with gangliosidosis diseases..

N-butyldeoxygalactonojirimycin reduces brain ganglioside and GM2 content in neonatal Sandhoff disease mice. - ImmunologyN-butyldeoxygalactonojirimycin reduces brain ganglioside and GM2 content in neonatal Sandhoff disease mice. - Immunology
Sandhoff disease involves the CNS accumulation of ganglioside GM2 and asialo-GM2 (GA2) due to inherited defects in the beta-subunit gene of beta-hexosaminidase A and B (Hexb gene). Accumulation of these glycosphingolipids (GSLs) produces progressive neurodegeneration, ultimately leading to death. Substrate reduction therapy (SRT) aims to decrease the rate of glycosphingolipid (GSL) biosynthesis to compensate for the impaired rate of catabolism. The imino sugar, N-butyldeoxygalactonojirimycin (NB-DGJ) inhibits the first committed step in GSL biosynthesis. NB-DGJ treatment, administered from postnatal day 2 (p-2) to p-5 (600 mg/kg/day)), significantly reduced total brain ganglioside and GM2 content in the Sandhoff disease (Hexb(-/-)) mice, but did not reduce the content of GA2. We also found that NB-DGJ treatment caused a slight, but significant elevation in brain sialidase activity. The drug had no adverse effects on viability, body weight, brain weight, or brain water content in the mice. No significant

HEXB - WikipediaHEXB - Wikipedia
Beta-hexosaminidase subunit beta is an enzyme that in humans is encoded by the HEXB gene. Hexosaminidase B is the beta subunit of the lysosomal enzyme beta-hexosaminidase that, together with the cofactor GM2 activator protein, catalyzes the degradation of the ganglioside GM2, and other molecules containing terminal N-acetyl hexosamines. Beta-hexosaminidase is composed of two subunits, alpha and beta, which are encoded by separate genes. Both beta-hexosaminidase alpha and beta subunits are members of family 20 of glycosyl hydrolases. Mutations in the alpha or beta subunit genes lead to an accumulation of GM2 ganglioside in neurons and neurodegenerative disorders termed the GM2 gangliosidoses. Beta subunit gene mutations lead to Sandhoff disease (GM2-gangliosidosis type II). The HEXB gene lies on the chromosome location of 5q13.3 and consists of 15 exons, spanning 35-40Kb. HEXB consists of 556 amino acid residues and weighs 63111Da. HEXB is one of the two subunits forming β-hexosaminidase which ...

Dramatically Different Phenotypes in Mouse Models of Human Tay-Sachs and Sandhoff Diseases : Human Molecular Genetics - oiDramatically Different Phenotypes in Mouse Models of Human Tay-Sachs and Sandhoff Diseases : Human Molecular Genetics - oi
We have generated mouse models of human Tay-Sachs and Sandhoff diseases by targeted disruption of the Hexa (α subunit) or Hexb (β subunit) genes, respectively, encoding lysosomal β-hexosaminidase A (structure, α) and B (structure, ββ). Both mutant mice accumulate GM2 ganglioside in brain, much more so in Hexb −/− mice, and the latter also accumulate glycolipid GA2. Hexa −/− mice suffer no obvious behavioral or neurological deficit, while Hexb −/− mice develop a fatal neurodegenerative disease, with spasticity, muscle weakness, rigidity, tremor and ataxia. The Hexb −/− but not the Hexa −/− mice have massive depletion of spinal cord axons as an apparent consequence of neuronal storage of GM2. We propose that Hexa −/− mice escape disease through partial catabolism of accumulated GM2 via GA2 (asialo-GM2) through the combined action of sialidase and β-hexosaminidase B.. ...

Sandhoff disease is a rare, inherited lipid storage disorder that progressively destroys nerve cells in the brain and spinal cord. It is caused by a deficiency of the enzyme beta-hexosaminidase, which results in the harmful accumulation of certain fats (lipids) in the brain and other organs of the body. Sandhoff disease is a severe form of Tay-Sachs disease, the incidence of which had been particularly high in people of Eastern European and Ashkenazi Jewish descent, but Sandhoff disease is not limited to any ethnic group. Each parent must carry the defective gene and pass it on to the child. Individuals who carry only one copy of the mutated gene typically do not show signs and symptoms of the disorder.

NSAIDs increase survival in the Sandhoff disease mouse: synergy with N-butyldeoxynojirimycin. - Department of PharmacologyNSAIDs increase survival in the Sandhoff disease mouse: synergy with N-butyldeoxynojirimycin. - Department of Pharmacology
The GM2 gangliosidoses are caused by incomplete catabolism of GM2 ganglioside in the lysosome, leading to progressive storage and a neurodegenerative clinical course. An inflammatory response (microglial activation, macrophage infiltration, oxidative damage) has been found to be a consequence of GM2 storage in the brain, although it remains unclear whether this contributes to pathogenesis or disease progression. In this study, we treated Sandhoff disease mice with nonsteroidal antiinflammatory drugs (indomethacin, aspirin, and ibuprofen) and antioxidants (L-ascorbic acid and alpha-tocopherol acetate). The treated mice lived significantly longer than untreated littermates (12-23%, p |0.0001) and showed a slower rate of disease progression (p |0.001). When aspirin treatment was combined with substrate reduction therapy, synergy resulted (11%, p |0.05) with a maximum improvement of 73% in survival (p |0.00001). This study demonstrates that inflammation contributes to disease progression and identifies

HEXA - wikidocHEXA - wikidoc
The HEXA gene is a protein encoding gene that codes for the lysosomal enzyme beta-hexosaminidase. This enzyme, combined with the GM2 activator protein, is responsible for the breakdown of ganglioside GM2 within the lysosome. Defects in the HEXA gene, however, prevent this degradation, leading to a buildup of toxins in brain and spinal cord cells. This fatal genetic disorder is called Tay-Sachs disease. Because the Tay-Sachs gene defect mainly affects neural cells, a patient with the HEXA mutation will experience a quick deterioration of motor and mental function before dying around the age of three or four. [8] A knockout model, which is a mouse that has been genetically modified to observe the effects of inactivation of or damage to certain genes, found that the mice that were administered the HEXA gene experienced many of the same symptoms of Tay-Sachs, with one exception: GM2 buildup was distributed differently in the brains of the mice than in those of a typical human Tay-Sachs patient. ...

Patients with late-onset Tay-Sachs or Sandhoff disease will be given increasing doses of Pyr, up to but not exceeding doses used to treat malaria, over a 5-month period. We will follow the effect of the treatment on the levels of Hex A enzyme activity in white blood cells, which are considered to be a reflection of the likely enzyme activity in the brain. We will also follow some other lysosomal enzyme activities to determine if the effect is specific for Hex A. Furthermore, we will examine the effect of the treatment on the levels of GM2-ganglioside in the white blood cells. On the basis of the studies done on cultured skin cells, we expect that treatment with Pyr will increase the levels of Hex A and decrease the accumulation of GM2-ganglioside in the white blood cells ...

Extended-spectrum2
  • Antibiotic resistance rates of extended spectrum beta-lactamase producing Escherichia coli and Klebsiella spp. (thefreedictionary.com)
  • Transcontinental importation into the UK of Escherichia coli expressing a plasmid-mediated AmpC-type betalactamase exposed during an outbreak of SHV-5 extended-spectrum beta-lactamase in a Leeds hospital. (thefreedictionary.com)
GalNAc1
  • Beta-hexosaminidase (HEX) cleaves the terminal N-acetyl galactosamine (GalNAc) from glucosaminoglycans (GAGs) and any other molecules containing a terminal GalNAc. (reactome.org)
GlcNAc1
  • Plays a role in peptidoglycan recycling by cleaving the terminal beta-1,4-linked N-acetylglucosamine (GlcNAc) from peptide-linked peptidoglycan fragments, giving rise to free GlcNAc, anhydro-N-acetylmuramic acid and anhydro-N-acetylmuramic acid-linked peptides. (uniprot.org)
Glycosyl hydrolases1
  • Both beta-hexosaminidase alpha and beta subunits are members of family 20 of glycosyl hydrolases. (vwr.com)
Enzymes3
  • In mammals, the internalization of microorganisms at sites of infection by macrophages proceeds via a sequential chain of events that leads to the sequestration of pathogens in phagosomes, where they are killed and degraded by hydrolytic enzymes. (mcponline.org)
  • Any of various enzymes that hydrolyze and inactivate beta-lactam antibiotics such as penicillin, found in many antibiotic-resistant bacteria. (thefreedictionary.com)
  • Measuring the population of enzymes whose active site was occupied by a polymer chain revealed that Cel7A was bound predominantly via its active site. (embl-heidelberg.de)
Steroids1
  • Steroids differ from one another in the structure of various side chains and additional rings. (thefreedictionary.com)
Terminal1
  • Synthetic peptides from the variable region of the 4-kDa C-terminal moiety of tubulin subunits, alpha-(430-441) and beta-(422-434), bind to MAP-2 and to the MAP tau, and a preferential interaction of the beta peptide is observed. (termsreign.tk)
Alpha chains1
  • and hexosaminidase S is a homodimer of alpha chains. (wikipedia.org)
Abnormal1
  • Where there are abnormal beta chains both hexosaminidase A and B will be affected. (patient.info)
Glycan chain1
  • Glycolipids are complex molecules consisting of a ceramide lipid moiety linked to a glycan chain of variable length and structure. (frontiersin.org)
Leukocytes1
Activity1
  • 9 MBLs have not only become a source of increased morbidity and mortality but also represent a clinical threat due to their unrivalled spectrum of activity and their resistance to therapeutic serine beta-lactamase inhibitors. (thefreedictionary.com)
