Gangliosides and hearing

Biochimica et Biophysica Acta (BBA) - General Subjects, 2017
Severe auditory impairment observed in GM3 synthase-deficient mice and humans indicates that glycosphingolipids, especially sialic-acid containing gangliosides, are indispensable for hearing. Gangliosides associate with glycoproteins to form membrane microdomains, the composition of which plays a special role in maintaining the structural and ...

Gangliosides of Melanoma

The Journal of Dermatology, 1992
AbstractThe relationships between the ganglioside composition of melanomas and their biologic behavior were investigated. (1) The amount of GM2 and/or GD2 in melanoma cells injected into nude mice correlated with the tumor growth rate. (2) GD2 content of melanoma cell lines correlated with sensitivity to radiation and vincristine. (3) GM2 expression of

Gangliosides in Neuroblastomas

Neurochemical Pathology, 1988
Neuroblastomas from children presenting with tumors at various ages and different primary sites (abdominal, adrenals, pelvic, and thoracic) were studied. Analysis of the ganglioside patterns of 53 tumors indicated that patients who were either disease positive 2 yr following surgery or dead of disease, had significantly (p less than 0.005) less GT1b ...

Gangliosides and parkinsonism

Neurology, 1993
The protective effect of GM1 ganglioside against nerve cell death induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) was analyzed in monkey mesencephalon. Administration of GM1 before and during MPTP treatment improved motor performances compared with MPTP-treated animals that received saline rather than GM1.

Gangliosides and atherosclerosis

Lipids, 1994
AbstractThe ganglioside levels in atherosclerotic lesions of human aorta are considerably higher than those in unaffected areas of aorta, and atherosclerotic patients frequently have increased concentrations of serum gangliosides. The present review summarizes recent findings that suggest the possible involvement of aortic gangliosides in platelet ...

Gangliosides and Tumors

2018
Tumor-associated gangliosides play important roles in regulation of signal transduction induced by growth-factor receptors including EGFR, FGFR, HGF and PDGFR in a specific microdomain called glycosynapse in the cancer cell membranes, and in interaction with glycan recognition molecules involved in cell adhesion and immune regulation including ...

Gangliosides as Immunomodulators

2007
Gangliosides are glycosphingolipids expressed at the outer leaflet of the plasmatic membrane of cells from vertebrate organisms. These molecules exert diverse biological functions including modulation of the immune system responses. Aberrant expression of gangliosides has been demonstrated on malignant cells. Besides expression on tumor cell membranes,

Ganglioside Storage Diseases [PDF]

open access: possibleNew England Journal of Medicine, 1971
For almost 100 years Tay-Sachs disease was the only ganglioside storage disease known. A second inborn error of ganglioside metabolism, generalized gangliosidosis, was discovered in 1965.13,35 Three additional ganglioside storage diseases have recently been uncovered,4,3,52,66,74 bringing the total to five.36 Of these, three involve storage of ...

Calorimetric studies on various gangliosides and ganglioside-lipid interactions

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1982
Differential scanning calorimetry was used to investigate the thermotropic behaviour of various gangliosides differing in size and in the net negative charge. It was found that the number and the position of the negative charges in the headgroup region influence strongly the phase transition profiles.
