Basic fibroblast growth factor-induced proliferation of primary astrocytes. evidence for the involvement of sphingomyelin biosynthesis.
We recently reported that the marked decrease in cellular ceramide in primary astrocytes is an early event associated with the mitogenic activity of basic fibroblast growth factor (bFGF) (Riboni, L., Viani, P., Bassi, R., Stabieini, A., and Tettamanti, G. (2000) GLIA 32, 137-145). Here we show that a rapid activation of sphingomyelin biosynthesis appears to be the major mechanism responsible fo...
متن کاملNoncompetitive, chemokine-mediated inhibition of basic fibroblast growth factor-induced endothelial cell proliferation.
The proinflammatory and chemoattractant chemokine interleukin-8 (IL-8) inhibits cell proliferation induced by basic fibroblast growth factor (bFGF) in mouse endothelial cells isolated from subcutaneous sponge implant (sponge-induced mouse endothelial cells) and in bovine aortic endothelial GM 7373 cells. The mechanism of action of IL-8 was investigated in GM 7373 cells. IL-8 did not prevent the...
متن کاملInhibitory effects of ginsenosides on basic fibroblast growth factor-induced melanocyte proliferation
BACKGROUND UV-B-exposed keratinocytes secrete various paracrine factors. Among these factors, basic fibroblast growth factor (bFGF) stimulates the proliferation of melanocytes. Ginsenosides, the major active compounds of ginseng, are known to have broad pharmacological effects. In this study, we examined the antiproliferative effects of ginsenosides on bFGF-induced melanocyte proliferation. M...
متن کاملBasic Fibroblast Growth Factor–Induced Endothelial Proliferation and NO Synthesis Involves Inward Rectifier
Objectives—Inward rectifier K currents (Kir) determine the resting membrane potential and thereby modulate essential Ca -dependent pathways, like cell growth and synthesis of vasoactive agents in endothelial cells. Basic fibroblast growth factor (bFGF) acts as a vasodilatator and angiogenic factor. Therefore, we investigated the effect of bFGF on Kir and assessed the role in proliferation and n...
متن کاملBasic fibroblast growth factor-induced endothelial proliferation and NO synthesis involves inward rectifier K+ current.
OBJECTIVE Inward rectifier K+ currents (K(ir)) determine the resting membrane potential and thereby modulate essential Ca2+-dependent pathways, like cell growth and synthesis of vasoactive agents in endothelial cells. Basic fibroblast growth factor (bFGF) acts as a vasodilatator and angiogenic factor. Therefore, we investigated the effect of bFGF on K(ir) and assessed the role in proliferation ...
