背景介绍 FGF-9 is an autocrine and paracrine prostatic growth factor expressed by prostatic stromal cells. FGF-9 induces osteoblast proliferation and new bone formation in a bone organ assay. FGF-9 is produced by many prostate cancer cells and contributes to prostate cancer-induced new bone formation and may participate in the osteoblastic progression of prostate cancer in bone. It is also an autocrine and/or paracrine neurotrophic factor that promotes the survival of motoneurons and upregulates choline acetyl-transferase activity. FGF-9 enhances survival of AChE-positive neurons, increasing their mean soma size. It also up-regulates their choline acetyltransferase activity as potently as NGF and the effect is greater than that elicited by bFGF, CNTF, or GDNF. FGF-9 acts as a survival factor for neurons but does not promote neurite outgrowth. FGF-9 has been shown to mediate its effects by binding to FGF receptors. It efficiently activates the FGFR2c splice form of FGFR2 and the FGFR3b and FGFR3c splice isoforms of FGFR3. 产品介绍 Recombinant Fibroblast Growth Factor-9 is a disulfide-linked monomer protein consisting of 208 amino acid residues, and migrates as an approximately 23 kDa protein under non-reducing and reducing conditions in SDS-PAGE.
