摘要：
Fibroblast growth factor(FGF) signal transduction pathway is correlated with many diseases, such as cancer, skeletal dysplasias, olfactory syndromes and so on. P(VYMSPF), a small peptide, is an antagonist of aFGF. In order to investigate the impact of the peptide P on aFGF signal transduction pathway, the proteomes of NIH3T3 cell stimulated under different conditions(aFGF+heparin sodium and aFGF+heparin sodium+P) were extracted and analyzed by 2DE, five differentially expressed protein spots were selected and identified via ESI-MS/MS. The result indicates that the peptide P has a great influence on the function of aFGF such as metabolism, protein translation and cytoskeleton formation; the target signal pathway of the peptide P may be MAPK pathway and the peptide P might also affect the PLCγ pathway. The article provides a new insight into the peptide P as a potential anticancer drug.
