| 摘要 |
The invention provides an isolated antibody or antibody fragment thereof that binds an extracellular epitope of a fibroblast growth factor receptor-4 (FGFR4) that is expressed by mammalian cells and inhibits cancer cell invasion. Optionally, the antibody or fragment thereof binds an epitope of FGFR4 that is bound by monoclonal antibody F90-10C5, or comprises complementarity determining regions identical to those of monoclonal antibody F90-10C5. Also provided are methods of using the antibody or fragment thereof to modulate invasion, ingrowth, or metastasis of cancer cells and treat cancer in a subject. The invention additionally provides a method of identifying an antibody or antibody fragment that inhibits invasiveness. |
