Inhibition of angiogenesis Inhibition of tumor growth Inhibition of inflammation Inhibition of excessive wound healing Reduction of resistance of tumor cells to chemotherapeutic agents Development of assays to discover new compounds that affect FGF signalling
Fibroblast growth factors (FGFs) regulate diverse cellular processes including growth and differentiation. In addition, aberrant FGF signaling has been implicated in tumor progression. FGFs are also pro-inflammatory growth factors that have been implicated in promoting pathological angiogenesis in chronic inflammatory disease. Therefore, the FGF signaling pathway is an attractive target for cancer and inflammatory disease therapy. However, specific antagonists of this pathway are not well characterised. Researchers at the University of California, Davis have developed novel peptides derived from FGF1 that can bind to FGF receptors and block integrin-FGF receptor cross talk, inhibiting FGF signaling in a dominant negative fashion. These peptides show promise as therapeutic agents and tools for compound discovery for the advancement of cancer therapy and treatment of inflammation.
