The structure and functions of glucocerebrosidase

Mutations in this gene cause Gaucher disease, a lysosomal storage disease characterized by an accumulation of glucocerebrosides. A related pseudogene is approximately 12 kb downstream of this gene on chromosome 1.

Alternative splicing results in multiple transcript variants. Using an unbiased methodology, this study showed that carriers of severe GBA mutations are at higher risk for Parkinson's disease relative to carriers of the mild mutations.

The mutation spectrum of GBA exhibits ethnic and regional disparity in Asian patients. LP was the most frequent mutation accounted for The LP homozygote genotype was associated with severe type 1 Gaucher disease.

These results indicated activation of Unfolded Protein Response UPR in different cell types derived from Gaucher disease patients, highlighting the generality of this process in this disease.

The data of this study suggested that the prominent cognitive impairment in Glucocerebrosidase GBA -associated Parkinson disease seems not primarily associated with specific Abeta and Tau profiles in CSF. This study demonstrated that GBA status appears to be an important predictor for non-motor symptom disease progression, after deep brain stimulation surgery.

The results of this study support a connection between the loss of beta-glucocerebrosidase-1 function, cholesterol accumulation, and the disruption of cellular homeostasis in GBA1-PD. Similarly to other studies, our results suggest that mutations in GBA and LRRK2 influence the clinical signs of the Parkinson's disease, with significant implications for handling of specific patient groups.

In longitudinally assessed, autopsied Parkinson disease cases, those with GBA mutations had a younger age at death but there was no evidence for clinical or neuropathological differences compared to cases without GBA mutations.

Low Glucosylceramidase serum levels are associated with Gaucher disease. Parkinson's disease is associated with mutations in GBA. Ashkenazi Jews GBA carriers were singled at a significantly earlier age at diagnosis compared to noncarriers.

GBA mutations are also an important risk factor for DLB development in the Spanish population, are associated with earlier disease onset, and are more prevalent in men. Review Mutant GBA proteins cause increases in alpha-synuclein levels, while an inhibition of GBA by alpha-synuclein has been also demonstrated in Gaucher disease patients with Parkinson disease.

Parkinson patient who carry mutations in the GBA gene demonstrates more significant cognitive decline compared to idiopathic parkinson patients.

Mesenchymal stem cells with reduced GBA activity are prone to apoptosis and senescence due to impaired autophagy and DNA repair capacity. Local lysosomal conditions may be even more critical for some mutant lysosomal hydrolases, e. In Niemann-Pick disease type C disease, characterized by the cholesterol primary storage, GlcCer secondary accumulation could be triggered by SM secondary accumulation.

In a Flanders-Belgian cohort, carrier status of a heterozygous glucocerebrosidase GBA mutation was a strong genetic risk factor for Parkinson's disease PD. The GBA mutation frequency of 4. Rab7 accumulated in GCase deficient cells, supporting the notion that lysosomal recycling is impaired.

Since recombinant GCase can reverse ALR impairment, we anticipate that strategies to restore GCase activity in the brains of both sporadic patients with PD and those with GBA1 mutations will improve autophagy lysosomal pathway, preventing the accumulation of a-synuclein and spread of pathology.

GBA variants predict a more rapid progression of cognitive dysfunction and motor symptoms in patients with Parkinson's.

Mutations in the GBA gene were associated with more severe motor and cognitive dysfunction, supporting a specific contribution of the GBA gene or lysosome function in Lewy body disease among Ashkenazi Jews. Combination of chemo drug with beta-glucosidase 1 inhibitor sensitized hepatocellular carcinoma HCC cells to chemotherapy.

Our data support b-glucosidase 1 as a HCC biomarker due to its prognosis significance the study supported that GBA mutations were a risk factor for Parkinson's disease in the European population The clinical phenotype of GBA-associated neurodegenerative disease is more heterogeneous than previously assumed, including phenotypes not usually associated with underlying alpha-synucleinopathies.

This merits a comprehensive review of the current cell biological processes and pathological pictures involving Parkinson's disease associated with GBA mutations GBA mutations were found to be a common genetic risk factor for Parkinson disease in Eastern Canadian patients. In this study, we produced hGCase through the direct injection of recombinant adenovirus in the mammary gland of a non-transgenic goat findings showed that Gaucher disease GD -associated GBA mutations were not only associated with the development of Parkinson's disease PD but also had a great impact on developing dementia and psychosis in the clinical course of PD This study discovery that EK of GBA negatively impacts cognitive performance approximately doubles the proportion of PD patients This study showed the presence of six LRRK2 p.

GS and nine GBA p. NS mutation carriers in Parkinson disease. Its genetic variation influences Parkinson disease risk, age of onset, and progression.

Our findings indicate that dGBA1b plays an important role in the metabolism of protein aggregates, but that the deleterious consequences of mutations in dGBA1b are largely independent of a-synuclein GBA1 mutations interfere with TFEB-mediated lysosomal biogenesis, and that the action of GBA in maintaining a functioning pool of lysosomes is exerted in part through TFEB.

The most highly correlated pair of residue variations is alpha-synuclein A53T and glucocerebrosidase GE. Intriguingly, the A53T mutation is a Parkinson's disease risk factor in humans, suggesting the pathology associated with this mutation This study did not demonstrate glucocerebrosidase substrate accumulation in Parkinson's disease brains with heterozygote GBA1 mutations in areas of the brain with low alpha-synuclein pathology.

The present study used a meta-analysis approach, pooling the appropriate data from published studies to investigate the association of GBA mutations and Parkinson's disease in a Chinese population.Structure The essential feature of a glycolipid is the presence of a monosaccharide or oligosaccharide bound to a lipid moiety.

The most common lipids in cellular membranes are glycerolipids and sphingolipids, which have glycerol or a sphingosine backbones, respectively. Other articles where Cerebroside is discussed: lipid storage disease: Gaucher’s disease, abnormal amounts of cerebrosides accumulate in the liver, spleen, bone marrow, and lymph nodes.

The defective enzyme is glucocerebrosidase. The excess lipids, stored in the large distended Gaucher cells that are typical of the disease, interfere with cell .

The structure and functions of glucocerebrosidase

Lewy body disease (LBD) development is enhanced by mutations in the GBA gene coding for glucocerebrosidase (GCase). The mechanism of this association is thought to involve an abnormal lysosomal system and we therefore sought to evaluate if lysosomal changes contribute to the pathogenesis of idiopathic LBD.

Glucocerebrosidase Variants by Inhibiting ER-Associated Degradation and Enhancing ER Folding of essential lysosomal hydrolytic functions [1]. Gaucher’s disease (GD), the most common LSD, is caused by loss of lysosomal activity but destabilize its native structure [4]. They are typically single amino acid substitutions that impair the.

The GBA gene provides instructions for making an enzyme called beta-glucocerebrosidase. This enzyme is active in lysosomes, which are structures inside cells that act as recycling centers. This enzyme is active in lysosomes, which are structures inside cells that act as recycling centers.

The study, “ β-Glucocerebrosidase modulators promote dimerization of β-glucocerebrosidase and reveal an allosteric binding site,” was published in the Journal of The American Chemical Society.

Gaucher disease is caused by mutations in the GBA1 gene, leading to a reduced activity of the lysosomal enzyme glucocerebrosidase (GCase).
