Abrogation of fibroblast activation protein enzymatic activity attenuates tumor growth.
Tumor-associated fibroblasts are functionally and phenotypically distinct from normal fibroblasts that are not in the tumor microenvironment. Fibroblast activation protein is a 95 kDa cell surface glycoprotein expressed by tumor stromal fibroblasts, and has been shown to have dipeptidyl peptidase and collagenase activity. Site-directed mutagenesis at the catalytic site of fibroblast activation ...
متن کاملPromotion of Cellular Growth and Motility Is Independent of Enzymatic Activity of Fibroblast Activation Protein-α.
BACKGROUND Fibroblast activation protein-alpha (FAPα) is a type-II integral membrane serine protease and is expressed in most stromal fibroblasts. Recent studies showed that FAPα is also expressed in certain cancer cells but its role is still uncertain. MATERIALS AND METHODS We analyzed the non-enzymatic activity of FAPα in breast cancer cells by introducing an enzymatic mutant FAPα (FAPS624A...
متن کاملProtein, a Serine Protease, in an Animal Model Promotion of Tumor Growth by Murine Fibroblast Activation
Fibroblast activation protein (FAP) is a type II integral membrane glycoprotein belonging to the serine protease family. Human FAP is selectively expressed by tumor stromal fibroblasts in epithelial carcinomas, but not by epithelial carcinoma cells, normal fibroblasts, or other normal tissues. FAP has been shown to have both in vitro dipeptidyl peptidase and collagenase activity, but its biolog...

متن کاملTargeting fibroblast activation protein inhibits tumor stromagenesis and growth in mice.
Membrane-bound proteases have recently emerged as critical mediators of tumorigenesis, angiogenesis, and metastasis. However, the mechanisms by which they regulate these processes remain unknown. As the cell surface serine protease fibroblast activation protein (FAP) is selectively expressed on tumor-associated fibroblasts and pericytes in epithelial tumors, we set out to investigate the role o...
