Abstract BACKGROUND Although histologically distinct, gliosarcomas and glioblastomas are treated according to the same standards. Fibroblast-activation-protein (FAP) is a component of tumor-specific subpopulation fibroblasts that play critical role in tumor growth invasion. Few case studies suggest an elevated expression FAP glioblastoma particularly strong gliosarcoma, possibly for its predomi...

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...

Cancer immunotherapy has primarily been focused on attacking tumor cells. However, given the close interaction between tumor cells and cancer-associated fibroblasts (CAFs) in the tumor microenvironment (TME), CAF-targeted strategies could also contribute to an integrated cancer immunotherapy. Fibroblast activation protein α (FAP α) is not detectible in normal tissues, but is overexpressed by CA...

Fibroblast activation protein (FAP) is a specific serine protease expressed in tumor stroma proven to be a stimulatory factor in the progression of some cancers. The purpose of this study was to investigate the effects of FAP knockdown on tumor growth and the tumor microenvironment. Mice bearing 4T1 subcutaneous tumors were treated with liposome-shRNA complexes targeting FAP. Tumor volumes and ...

BACKGROUND Cardiac amyloidosis due to familial amyloid polyneuropathy (FAP) includes restrictive cardiomyopathy, thickened cardiac walls, conduction disorders and cardiac denervation. Impaired blood pressure variability has been documented in FAP related to the Val30Met mutation. AIMS To document blood pressure variability in FAP patients with various mutation types and its relationship to th...

The human fibroblast activation protein alpha (FAP alpha) is a M(r) 95,000 cell surface antigen selectively expressed in reactive stromal fibroblasts of epithelial cancers, granulation tissue of healing wounds, and malignant cells of bone and soft tissue sarcomas. Normal adult tissues are generally FAP alpha-, but some fetal mesenchymal tissues transiently express the molecule. Because of its r...

Fibroblast activation protein (FAP) is the member of Dipeptidyl Peptidase IV (DPIV) gene family that is most similar to DPIV. Four members of this family, DPIV, FAP, DP8 and DP9 possess a rare catalytic activity, hydrolysis of a prolyl bond two residues from the substrate N terminus. Crystal structures show that the soluble form of FAP comprises two domains, an alpha/beta-hydrolase domain and a...

A Japanese family with atypical type I familial amyloidotic polyneuropathy (FAP) in Iiyama, Japan was studied. Most of the family members have dysfunctions in the central nervous system, in addition to typical symptoms of type I FAP. The transthyretin (TTR, also called prealbumin) gene of the atypical FAP(FAP-IY) was analyzed with recombinant DNA techniques and a RIA method. FAP-IY was found to...

Familial amyloid polyneuropathy (FAP) type IV (FINNISH) is a rare clinical entity with challenging neuropathy and cosmetic deficits. Amyloidosis can affect peripheral sensory, motor, or autonomic nerves. Nerve lesions are induced by deposits of amyloid fibrils and treatment approaches for neuropathy are challenging. Involvement of cranial nerves and atrophy in facial muscles is a real concern i...
