Energetics of heparin binding to human acidic fibroblast growth factor.
The binding of low-molecular-weight heparin to an amino-terminal-truncated, 132-amino-acid, human acidic fibroblast growth factor form has been studied by isothermal titration calorimetry. This technique yields values for the enthalpy change and equilibrium constant, from which the Gibbs energy and entropy change are also calculated. Experiments in different buffers and pH values show that the ...
متن کاملDetection of high levels of heparin binding growth factor-1 (acidic fibroblast growth factor) in inflammatory arthritic joints
The synovium from patients with rheumatoid arthritis (RA) and LEW/N rats with streptococcal cell wall (SCW) arthritis, an experimental model resembling RA, is characterized by massive proliferation of synovial connective tissues and invasive destruction of periarticular bone and cartilage. Since heparin binding growth factor (HBGF)-1, the precursor of acidic fibroblast growth factor (FGF), is a...
متن کاملFibroblast Growth Factor-1 vs. Fibroblast Growth Factor-2 in Ischemic Skin Flap Survival in a Rat Animal Model
BACKGROUND One of the main challenges in skin flap surgery is tissue ischemia and following necrosis. The present study compares the effects of fibroblast growth factors 1 and 2 on increasing cutaneous vasculature, improving ischemia, and preventing distal necrosis in ischemic skin flaps in rat model. METHODS Thirty rats were allocated into 3 groups (n=10) and 2×8 cm dorsal rando...
متن کاملConversion of a paracrine fibroblast growth factor into an endocrine fibroblast growth factor.
FGFs 19, 21, and 23 are hormones that regulate in a Klotho co-receptor-dependent fashion major metabolic processes such as glucose and lipid metabolism (FGF21) and phosphate and vitamin D homeostasis (FGF23). The role of heparan sulfate glycosaminoglycan in the formation of the cell surface signaling complex of endocrine FGFs has remained unclear. Here we show that heparan sulfate is not a comp...
متن کاملHepatocyte growth factor as a hematopoietic regulator.
Hepatocyte growth factor (HGF) was originally isolated as a mitogen for adult hepatocytes, but this cytokine is now regarded as a multi-functional factor. In the present study, we show that the mouse liver in the middle and/or late stage of the fetal life expresses both HGF and c-met (its receptor) messages. HGF and c-met mRNA are coexpressed not only in the adherent layers of fetal liver long-...
