Substitution of D-Trp 32 in NPY Destabilizes the Binding Transition State to the Y1 Receptor Site in SK-N-MC Cell Membranes
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1997-04)
The retention rate of the spin label 3-isothiocyanto methyl-2,2,5,5-tetramethyl-1-pyrrolidinyl oxyl spin label (proxyl) attached to the porcine N-acetyl-NPY peptide and the porcine N-acetyl-D-Trp 32 -NPY peptide at Lys 4 ...
Isolation of a novel plant lectin with an unusual specificity from Calystegia sepium
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1997-01)
A novel plant lectin has been isolated from the rhizomes of Calystegia sepium (hedge bindweed) and partially characterized. The lectin is a dimeric protein composed of two identical non-covalently linked subunits of 16kDa. ...
Differential effect of glucose deprivation on MAPK activation in drug sensitive human breast carcinoma MCF-7 and multidrug resistant MCF-7/ADR cells
(Kluwer Academic Publishers; Springer Science+Business Media, 1997-05)
We have investigated the effect of glucose deprivation treatment on the activation of mitogen activated protein kinases (MAPKs) in the drug-sensitive human breast carcinoma cells (MCF-7) and its drug resistant variant ...
Protein Kinase Inhibitors Block Neurite Outgrowth from Explants of Goldfish Retina
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1997-10)
A role for protein phosphorylation in the process of neurite outgrowth has been inferred from many studies of the effects of protein kinase inhibitors and activators on cultured neurotumor cells and primary neuronal cells ...
Application of membrane-based preferential transport to whole broth processing
(Wiley Subscription Services, Inc., A Wiley Company, 1997-08-20)
Preferential transport in adsorptive membranes can be used to selectively remove biochemicals directly from fermentation broths. During preferential transport, an adsorbing solute is selectively transported across the ...
HLA class II haplotype and sequence analysis support a role for DQ in narcolepsy
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-09)
A systematic haplotype and sequencing analysis of the HLA -DR and - DQ region in patients with narcolepsy was performed. Five new (CA) n microsatellite markers were generated and positioned on the physical map across the ...
Purification and carbohydrate-binding specificity of Agrocybe cylindracea lectin
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1997-01)
A lectin was isolated from fruiting bodies of Agrocybe cylindracea by two ion-exchange chromatographies and gel filtration on Toyopearl HW55F. The lectin was homogeneous on polyacrylamide gel electrophoresis and its molecular ...
Wortmannin Blocks Goldfish Retinal Phosphatidylinositol 3-Kinase and Neurite Outgrowth
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1997-04)
The goldfish retina has been used extensively for the study of nerve regeneration. A role for phosphatidylinositol 3-kinase (PI3K) in neurite outgrowth from goldfish retinal explants has been examined by means of wortmannin ...
Purification and characterization of a new mannose-specific lectin from Sternbergia lutea bulbs
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1997-01)
A new mannose-binding lectin was isolated from Sternbergia lutea bulbs by affinity chromatography on an α(1-2)mannobiose-Synsorb column and purified further by gel filtration. This lectin (S. lutea agglutinin; SLA) appeared ...
Lipid-Dependent Modulation of Ca 2+ Availability in Isolated Mossy Fiber Nerve Endings
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1997-10)
An enhancement of glutamate release from hippocampal neurons has been implicated in long-term potentiation, which is thought to be a cellular correlate of learning and memory. This phenomenom appears to be involved the ...
