Basic, not acidic fibroblast growth factor stimulates proliferation of cultured human retinal pigment epithelial cells.
PURPOSE In this study, we evaluated a possible effect of acidic and basic fibroblast growth factor (aFGF, bFGF) on the proliferation of human retinal pigment epithelial (RPE) cells in culture. As the RPE is the primary source for bFGF in the retina, such an effect would suggest autocrinic actions of FGFs. METHODS Primary cultures of human and porcine RPE and an established human RPE cell line...
متن کاملActivation of hepatic stem cell compartment in the rat: role of transforming growth factor alpha, hepatocyte growth factor, and acidic fibroblast growth factor in early proliferation.
We have demonstrated previously a pronounced increase in the expression of hepatocyte growth factor (HGF) (Z. Hu, R. P. Evarts, K. Fujio, E. R. Marsden, and S. S. Thorgeirsson, Am. J. Pathol., 142: 1823-1830, 1993), transforming growth factor alpha (TGF-alpha) (R. P. Evarts, H. Nakatsukasa, E. R. Marsden, Z. Hu, and S. S. Thorgeirsson, Mol. Carcinog., 5: 25-31, 1992), and acidic fibroblast grow...
متن کاملIntramolecular backfolding of the carboxyl-terminal end of MxA protein is a prerequisite for its oligomerization.
Mx proteins are large GTPases, which play a pivotal role in the interferon type I-mediated response against viral infections. The human MxA inhibits the replication of several RNA viruses and is organized in oligomeric structures. Using two different experimental approaches, the mammalian two-hybrid system and an interaction dependent nuclear translocation approach, three domains in the carboxy...
متن کاملMutagenesis of the crystal contact of acidic fibroblast growth factor
An attempt has been made to improve a crystal contact of human acidic fibroblast growth factor (haFGF; 140 amino acids) to control the crystal growth, because haFGF crystallizes only as a thin-plate form, yielding crystals suitable for X-ray but not neutron diffraction. X-ray crystal analysis of haFGF showed that the Glu81 side chain, located at a crystal contact between haFGF molecules, is in ...
متن کاملStimulation of proliferation of a human osteosarcoma cell line by exogenous acidic fibroblast growth factor requires both activation of receptor tyrosine kinase and growth factor internalization.
U2OS Dr1 cells, originating from a human osteosarcoma, are resistant to the intracellular action of diphtheria toxin but contain toxin receptors on their surfaces. These cells do not have detectable amounts of fibroblast growth factor receptors. When these cells were transfected with fibroblast growth factor receptor 4, the addition of acidic fibroblast growth factor to the medium induced tyros...
