The aim of this study was to determine the prognostic significance of blood VEGF and blood and urinary basic fibroblast growth factor (bFGF) levels in osteosarcoma patients, both at diagnosis and during treatment.
Our study demonstrated that miR-646 might be a tumor suppressor in osteosarcoma via the regulation of FGF2, which provided a potential prognostic biomarker and therapeutic target.
Apurinic/apyrimidinic endonuclease 1 induced upregulation of fibroblast growth factor 2 and its receptor 3 induces angiogenesis in human osteosarcoma cells.
The combined blockade of the signaling pathways of several growth factors, including Fgf2, might be useful in controlling the aggressiveness of osteosarcoma.
FGF-2 treatment of osteosarcoma cells resulted in a significant increase (P ≤ 0.01) in MG63 cell migration, similar to that caused by PTH(1-34). mRNA expression analysis of cells treated with PTH(1-34) showed a strong increase in FGF-2 transcript levels (P = 0.0015).
We examined the effect of IL-1 on FGF-2 mRNA and protein expression in human osteosarcoma MG-63 osteoblasts, normal human osteoblasts (NHOB), and osteoblasts from osteoarthritic patients (F2 and F13).
