Endogenous ganglioside GM1 modulates L-type calcium channel activity in N18 neuroblastoma cells.
Digital imaging fluorescence microscopy was used to investigate the effect of the B subunit of cholera toxin on calcium homeostasis in neuroblastoma N18 cells. The B subunit, which binds specifically to ganglioside GM1 in the outer leaflet of the cell membrane, was found to induce a sustained increase of intracellular calcium concentration ([Ca2+]i). The increase in [Ca2+]i was not observed in ...
متن کاملThe relationship between glycosylation and glycoprotein metabolism of mouse neuroblastoma N18 cells.
Two inhibitors of glycosylation, glucosamine and tunicamycin, were utilized to examine the effect of glycosylation inhibition in mouse neuroblastoma N18 cells on the degradation of membrane glycoproteins synthesized before addition of the inhibitor. Treatment with 10 mM-glucosamine resulted in inhibition of glycosylation after 2h, as measured by [3H]fucose incorporation into acid-insoluble macr...
متن کاملMedian nerve SEP after a high medullary lesion. Preserved N18 and absent P14 components. Case report.
Median nerve SEPs recorded from a patient with a high medullary lesion are described. The lesion involved the anteromedial and anterolateral right upper third of the medulla, as documented by MRI. Forty one days after the lesion, left median nerve SEP showed preserved N18 and absent P14 and N20 components; stimulation of the right median nerve evoked normal responses. These findings agree with ...
متن کاملPrecipitation kinetics in N18 P/M superalloy : experimental study and numerical modelling
Heat treatments of aeronautical turbine disks produced by powder metallurgy include y' solutionning, quenching and subsequent annealing. In the present work, the intragranular y' precipitation kinetics during the quench has been followed by dilatometry and transmission electron microscopy. The precipitation steps are studied on specimens "hyperquenched" from selected temperatures during a simul...
متن کاملIon permeation through 5-hydroxytryptamine-gated channels in neuroblastoma N18 cells
Ionic currents induced by 5-hydroxytryptamine (5-HT) in cultured neuroblastoma N18 cells were studied using whole-cell voltage clamp. The response was blocked by 1-10 nM 5-HT3 receptor-specific antagonists MDL 7222 or ICS 205-930, but not by 1 microM 5-HT1/5-HT2 receptor antagonist spiperone or 5-HT2 receptor-specific antagonist ketanserin. These 5-HT3 receptors seem to be ligand-gated channels...
