Nerve growth factor receptors on human melanoma cells in culture.
Purified mouse nerve growth factor (NGF)radiolabeled with 125I was tested for its ability to bind to a variety of different cultured cells. NGF binds readily to human and hamster melanoma cells but does not bind to many other cell lines. The three cell lines with the highest number of NGF receptors were derived from metastatic melanomas. One of these lines, A875, was studied in detail and was s...
متن کاملNerve growth factor in human semen: Effect of nerve growth factor on the normozoospermic men during cryopreservation process
Objective(s):Althoughroutinely applied in assisted reproductive technology, human sperm cryopreservation is not a completely successful procedure. Adverse effects of cryopreservation on the fertilization capacity, motility, morphology, and viability of spermatozoa have been proven; cryopreservation has also shown a role in sperm DNA fragmentation and infertility. The post-thaw survival of sperm...
متن کاملCo-expression of recombinant human nerve growth factor with trigger factor chaperone in E. coli
Nerve growth factor (NGF) is a neurotrophic factor that is functional in the survival, maintenance and differentiation of nervous system cells. This protein has three subunits, of which the beta subunit has the main activity. Its structure consists of a cysteine knot motif made up of beta strands linked by disulfide bonds. It can be used as a therapeutic agent in the treatment of many diseases....
متن کاملNerve growth factor receptors on dissociated neurofibroma Schwann-like cells.
Neurofibromatosis is a disorder which predominantly involves cellular elements of peripheral neural sheaths. Little is known about the regulation of differentiation and proliferation of cells comprising neurofibromas. Because nerve growth factor-like activity may be present in neurofibromas and the cells comprising neurofibromas are neural crest derivatives, we have investigated whether nerve g...
متن کاملNerve growth factor receptors on cultured rat Schwann cells.
Neonatal rat Schwann cells were grown in tissue culture and assayed for NGF receptors with time in culture. NGF receptor levels on freshly prepared Schwann cells (day 0) were low but increased dramatically during the first week in culture. Characterization of 125I-NGF binding to resuspended cells grown for 4 d in culture revealed that binding was not saturable at high ligand concentrations (50-...
