Direct quantitative determination of ceramide glycosylation in vivo: a new approach to evaluate cellular enzyme activity of glucosylceramide synthase

Journal of Lipid Research, 2010
Glucosylceramide synthase (GCS or GlcT-1), converting ceramide to glucosylceramide, is a key enzyme for the synthesis of glycosphingolipids. Due to its diverse roles in physiology and diseases, GCS may be a disease marker and drug target.

Glycolipid transfer protein expression is affected by glycosphingolipid synthesis. [PDF]

PLoS ONE, 2013
Members of the glycolipid transfer protein superfamily (GLTP) are found from animals and fungi to plants and red micro-alga. Eukaryotes that encode the glucosylceramide synthase responsible for the synthesis of glucosylceramide, the precursor for most ...

ARF6 regulates neuron differentiation through glucosylceramide synthase. [PDF]

PLoS ONE, 2013
The small GTPase ADP ribosylation factor 6 (ARF6) mediates endocytosis and has in addition been shown to regulate neuron differentiation. Here we investigated whether ARF6 promotes differentiation of Neuro-2a neuronal cells by modifying the cellular ...

Accumulation of glucosylceramide in the absence of the beta-glucosidase GBA2 alters cytoskeletal dynamics. [PDF]

PLoS Genetics, 2015
Glycosphingolipids are key elements of cellular membranes, thereby, controlling a variety of cellular functions. Accumulation of the simple glycosphingolipid glucosylceramide results in life-threatening lipid storage-diseases or in male infertility.

Cerebrospinal Fluid Profiles in Parkinson’s Disease: No Accumulation of Glucosylceramide, but Significant Downregulation of Active Complement C5 Fragment

Journal of Parkinson’s Disease, 2021
Background: As mutations in glucocerebrosidase 1 ( GBA1 ) are a major risk factor for Parkinson’s disease (PD), decreased GBA1 activity might play an important role in the pathogenesis of the disease.

Glucosylceramide in cerebrospinal fluid of patients with GBA-associated and idiopathic Parkinson’s disease enrolled in PPMI

npj Parkinson's Disease, 2021
Protein-coding variants in the GBA gene modulate susceptibility and progression in ~10% of patients with Parkinson’s disease (PD). GBA encodes the β-glucocerebrosidase enzyme that hydrolyzes glucosylceramide.

Saturated very long chain fatty acid configures glycosphingolipid for lysosome homeostasis in long-lived C. elegans

Nature Communications, 2021
The membrane lipids change with ageing and function as regulatory molecules, but the underlying mechanisms are incompletely understood. Here, the authors identify C22 glucosylceramide as a regulator of the longevity transcription factor SKN-1, and show ...

Substrate Reduction Therapy Reverses Mitochondrial, mTOR, and Autophagy Alterations in a Cell Model of Gaucher Disease

Cells, 2021
Substrate reduction therapy (SRT) in clinic adequately manages the visceral manifestations in Gaucher disease (GD) but has no direct effect on brain disease.

Human Brain Lipidomics: Investigation of Formalin Fixed Brains

Frontiers in Molecular Neuroscience, 2022
Human brain lipidomics have elucidated structural lipids and lipid signal transduction pathways in neurologic diseases. Such studies have traditionally sourced tissue exclusively from brain bank biorepositories, however, limited inventories signal that ...

Assay for the transbilayer distribution of glycolipids: selective oxidation of glucosylceramide to glucuronylceramide by TEMPO nitroxyl radicals

Journal of Lipid Research, 2000
In the present study, 2,2,6,6-tetramethylpiperidinooxy nitroxide (TEMPO) has been applied successfully to discriminate between glucosylceramide in the outer and inner leaflets of closed membrane bilayers.
