Thrombospondin-2 (TSP-2) is an endogenous negative regulator of vascularization in human cancer. TSP-2 regulates angiogenesis through binding and sequestration of the proangiogenic fibroblast growth factor-2 (FGF-2). However, it is unclear whether TSP-2 and FGF-2 are related to prognosis in non-small cell lung cancer (NSCLC). To study this issue, we measured serum (Elisa) levels of TSP-2 and FG...

The epithelial-mesenchymal transition (EMT) of proximal tubular epithelial cells (PTECs) into myofibroblasts contributes to the establishment of fibrosis that leads to end stage renal disease. FGF-2 induces EMT in PTECs. Because the interaction between FGF-2 and its receptor is mediated by heparan sulfate (HS) and syndecans, we speculated that a deranged HS/syndecans regulation impairs FGF-2 ac...

RATIONALE Prostaglandin (PG)E(2) exerts temporally distinct actions on blood vessels, immediate vasodilatation, and long-term activation of angiogenesis. OBJECTIVE To study the mechanism of PGE(2) induction of angiogenesis, we characterized its effect on fibroblast growth factor (FGF)-2 signaling in cultured endothelial cells and in ex vivo and in vivo assays of blood vessel formation. METH...

Fibroblast growth factor-21 (FGF-21) has been recently characterized as a new adipokine. The aim of this study was to assess FGF-21 levels in patients with rheumatoid arthritis (RA) and osteoarthritis (OA) and to study the relationship between FGF-21, disease activity and metabolic status. The levels of FGF-21 in serum and synovial fluid samples from 38 patients with RA and 42 control individua...

BACKGROUND Fibroblast growth factor-23 (FGF-23) is a hormone principally produced by osteocytes/osteoblasts. In patients with chronic kidney disease (CKD), FGF-23 levels are usually elevated and can reach up to 300 - 400 times the normal range. FGF-23 is regulated by local bone-related and systemic factors, but the relationship between circulating FGF-23 concentrations and bone remodeling and m...

The K-FGF/HST (FGF-4) growth factor is a member of the FGF family which is efficiently secreted and contains a single N-linked glycosylation signal. To study the role of glycosylation in the secretion of K-FGF, we mutated the human K-fgf cDNA to eliminate the glycosylation signal and the mutated cDNA was cloned into a mammalian expression vector. Studies of immunoprecipitation from the conditio...

OBJECTIVE Fibroblast growth factor-2 (FGF-2) exerts its cardioprotective effect through cell surface receptor signaling and may play a role in the normal maintenance of a healthy myocardium. One mechanism of FGF-2 release from contracting cardiomyocytes is through transient sarcolemmal disruption, with accumulation in the extracellular matrix. Continuous FGF-2 release would require a link to sy...

BACKGROUND In vivo and in vitro studies demonstrate the important roles of fibroblast growth factor (FGF) and FGF receptors (FGFRs) in neural survival, neurogenesis, oxidative stress, and emotional behavior. However, evidence on the role of FGF and FGFR in the pathophysiology of major depressive disorder (MDD) remains limited and inconclusive. OBJECTIVES This preliminary meta-analysis aimed t...

Fibroblast growth factor-23 (FGF-23) accumulates in blood of patients with chronic kidney disease (CKD) and is associated both with cardiovascular complications and disease progression. However, our knowledge of the sites and mechanisms that regulate plasma FGF-23 is still incomplete. We measured plasma intact FGF-23 across the kidney, splanchnic organs, and lung in 11 patients [estimated glome...

The combined effect of beta-tricalcium phosphate and basic fibroblast growth factor was observed in the regeneration of periodontal tissue in dogs. For this purpose, either beta-TCP and FGF-2 (beta-TCP/FGF-2 group) or FGF-2 alone (FGF-2 group) was applied in intrabony defects. The control group received beta-TCP alone. The tissues were histologically examined at 2, 4, or 8 weeks following treat...
