The granulocyte colony-stimulating factor (G-CSF) plays an important role in normal granulopoiesis. Its functions are mediated by specific receptors on the surface of responsive cells and, upon ligand binding, several cytoplasmic tyrosine kinases are activated. The cytoplasmic region proximal to the membrane of the G-CSF receptor (G-CSF-R) transduces proliferative and survival signals, whereas ...

As has been reported with other chemotherapeutic agents, evidence is emerging to suggest that increased taxol dose intensity is associated with improved therapeutic efficacy. Granulocyte colony-stimulating factor (G-CSF) effectively protects the bone marrow from taxol-induced neutropenia and allows for higher taxol dose administration. This report addresses the optimal use of G-CSF as a support...

Granulocyte colony-stimulating factor (G-CSF) is a glycoprotein of Mr of about 20,000, which stimulates proliferation and differentiation of progenitor cells of neutrophils. Recent clinical application of G-CSF has proven that this hormone is effective in treatment of patients suffering from neutropenia. In the last few years, the biochemical and molecular nature of the G-CSF receptor has been ...

Angiogenesis is regulated, under both physiological and pathological conditions, by numerous "non-classic" pro-angiogenic factors, including fibroblast growth factor-2 (FGF-2), vascular endothelial growth factor (VEGF), and placental growth factor (PlGF), and "non-classic" pro-angiogenic factors, including granulocyte colony stimulating factor (G-CSF), granulocyte macrophage colony stimulating ...
