Abstract
Ganglioside GD2 is associated with the proliferation and migration of breast cancer cells. However, the precise role of GD2 is unclear because its tendency to form dynamic and transient domains in cell plasma membranes (PMs), called lipid rafts, makes it difficult to observe. Previously, we developed fluorescent analogs of gangliosides (e.g., GM3 and GM1), which enabled the observation of lipid raft formation for the first time using single-molecule imaging. In this report, we describe the first chemical synthesis of a fluorescent ganglioside, GD2. A biophysical analysis of the synthesized analog revealed its raft-philic character, suggesting its potential to aid single-molecule imaging-based investigations into raft-associated interactions.
期刊介绍:
Glycoconjugate Journal publishes articles and reviews on all areas concerned with:
function, composition, structure, biosynthesis, degradation, interactions, recognition and chemo-enzymatic synthesis of glycoconjugates (glycoproteins, glycolipids, oligosaccharides, polysaccharides and proteoglycans), biochemistry, molecular biology, biotechnology, immunology and cell biology of glycoconjugates, aspects related to disease processes (immunological, inflammatory, arthritic infections, metabolic disorders, malignancy, neurological disorders), structural and functional glycomics, glycoimmunology, glycovaccines, organic synthesis of glycoconjugates and the development of methodologies if biologically relevant, glycosylation changes in disease if focused on either the discovery of a novel disease marker or the improved understanding of some basic pathological mechanism, articles on the effects of toxicological agents (alcohol, tobacco, narcotics, environmental agents) on glycosylation, and the use of glycotherapeutics.
Glycoconjugate Journal is the official journal of the International Glycoconjugate Organization, which is responsible for organizing the biennial International Symposia on Glycoconjugates.
