Attenuated familial adenomatous polyposis (AFAP) is a subtype of a condition known as familial adenomatous polyposis [2] (called FAP or classic FAP). People with FAP or AFAP will have an increased number of adenomatous colon polyps during their lifetime and an increased risk of developing colorectal cancer [3]. An adenomatous polyp is a lump filled with the cells that make mucous and line the i...

Late-onset amyloidogenic transthyretin (ATTR) type familial amyloid polyneuropathy (FAP) shows features distinct from those of early-onset hereditary ATTR type FAP. We herein describe an asymptomatic 68-year-old man with late-onset ATTR type FAP whose serial annual electrocardiograms demonstrated progressive left bundle branch block. Latent but severe cardiac involvement seems to be one feature...

A more complete understanding of the physiological and pathological role of lysophosphatidic acid (LPA) requires receptor subtype-specific agonists and antagonists. Here, we report the synthesis and pharmacological characterization of fatty alcohol phosphates (FAP) containing saturated hydrocarbon chains from 4 to 22 carbons in length. Selection of FAP as the lead structure was based on computa...

OBJECTIVES To investigate whether children with functional abdominal pain (FAP) show an attentional bias for their bodily activity, and whether receiving information about bodily activity influenced perception of bodily sensations. METHODS A total of 30 children with FAP and 30 healthy children performed a dot-probe task, in which they were shown sham pictures about their bodily activity. R...

Fibroblast activation protein (FAP), as described so far, is a type II cell surface serine protease expressed by fibroblastic cells in areas of active tissue remodelling such as tumour stroma or healing wounds. We investigated the expression of FAP by fibroblast-like synoviocytes (FLSs) and compared the synovial expression pattern in rheumatoid arthritis (RA) and osteoarthritis (OA) patients. S...

PURPOSE Fibroblast activation protein (FAP) is a serine protease that has emerged as a promising target for cancer therapy, either by direct abrogation of its proinvasive activity or by specific targeting of FAP-expressing cells with cytotoxic immunoconjugates. We aimed to select novel human-mouse cross-reactive antibodies and to test suitability for tumor therapy as radioimmunoconjugates in a ...

INTRODUCTION Inflammatory destructive arthritis, like rheumatoid arthritis (RA), is characterized by invasion of synovial fibroblasts (SF) into the articular cartilage and erosion of the underlying bone, leading to progressive joint destruction. Because fibroblast activation protein alpha (FAP) has been associated with cell migration and cell invasiveness, we studied the function of FAP in join...

Background: Ovarian cancer is the second most common cancer in women and the leading cause of cancer-related death from gynecological cancer. Fibroblast activation protein (FAP) is best known for its presence in stromal cancer-associated fibroblasts (CAFs). The aim of this study was to investigate the expression of FAP in ovarian cancer and its significance in clinical prognosis. Material and m...

As revealed by intracellular pools of nonactive Fas (Apo-1), export of Fas to the cell surface is often impaired in human tumors, thereby inactivating Fas ligand-mediated apoptosis. Here, we demonstrate that association with Fas-associated phosphatase 1 (FAP-1) attenuates Fas export to the cell surface. Forced expression of FAP-1 reduces cell surface Fas levels and increases the intracellular p...

The underlying data demonstrates that fibroblast activation protein (FAP) paves the way for fibrosarcoma cells, which require the proteolysis of the extracellular matrix (ECM) and basement membranes to intravasate from implanted subcutaneous primary tumors into blood vessels, be transported to distant organs where they extravasate from the blood vessels, reattach and proliferate to metastases. ...
