Fibroblast activation protein (FAP) is a candidate universal target antigen because it has been reported to be selectively expressed in nearly all solid tumors by a subset of immunosuppressive tumor stromal fibroblasts. We verified that 18/18 human tumors of various histologies contained pronounced stromal elements staining strongly for FAP, and hypothesized that targeting tumor stroma with FAP...

Fibroblast activation protein alpha (FAP) is a unique dual peptidase of the S9B serine protease family, being capable of both dipeptidyl peptidase and endopeptidase activities. FAP is expressed at low level in healthy adult organs including the pancreas, cervix, uterus, submaxillary gland and the skin, and highly upregulated in embryogenesis, chronic inflammation and tissue remodelling. It is a...

Familial adenomatous polyposis (FAP), due to germ-line mutation of the adenomatous polyposis coli (APC) gene, is characterized by development of colorectal adenomas and ultimately colorectal cancer. The usefulness of ornithine decarboxylase (ODC) activity and polyamine levels in normal-appearing colorectal mucosa to stratify risk for colorectal neoplasia by discriminating presymptomatic individ...

Familial adenomatous polyposis (FAP) and MUTYH-associated polyposis (MAP) are inherited disorders associated with multiple colorectal adenomas that lead to a very high risk of colorectal cancer. The somatic mutations that drive adenoma development in these conditions have not been investigated comprehensively. In this study we performed analysis of paired colorectal adenoma and normal tissue DN...

BACKGROUND Familial amyloid polyneuropathy (FAP) mainly targets the peripheral nervous system and heart. Early noninvasive detection of cardiac impairment is critical for therapeutic management. AIM To assess if amino-terminal pro-brain natriuretic peptide (NT-proBNP) or troponin T (cTnT) can predict echocardiographic left-ventricle (LV) impairment in FAP. METHODS Thirty-six asymptomatic ca...

BACKGROUND Approximately one-third of hepatoblastoma (HB) patients have associated congenital abnormalities, but familial recurrence is rare, except in association with familial adenomatous polyposis (FAP). This correlation may be missed if not actively sought, with implications for long-term outcome and management. METHODS We retrospectively investigated 3 families with an HB-familial polypo...

This case report aimed to characterize dento-osseous anomalies in Familial Adenomatous Polyposis (FAP) in a Brazilian patient. Furthermore, FAP was investigate for possible causative. This case report showed the importance of dento-osseous knowledge related to FAP. Early dento-osseous anomalies diagnosis revealed the need to followup FAP family members from childhood and was essential for subse...

We present an empirical analysis of the fast affine projection (FAP) algorithm to be used in an acoustic echo cancellation application using a fixed point DSP processor. We also introduce a modified FAP algorithm that was developed based on our FAP study. Our analysis study shows that the modified FAP algorithm is more robust and provides more consistent performance than the LMS algorithm. The ...

Testing for adenomatous polyposis coli (APC), the gene responsible for familial adenomatous polyposis (FAP), can now be offered to family members in FAP kindreds. With the availability of this test, genetic counseling has become a crucial tool for helping FAP patients and their relatives understand the syndrome and its implications and for assisting at-risk individuals in making informed decisi...

Fibroblast activation protein (FAP) is a type II integral membrane glycoprotein belonging to the serine protease family. It is selectively expressed by tumor stromal fibroblasts and transiently in the fibroblasts of healing wounds. FAP has been shown to modulate growth, differentiation, adhesion, and metastasis of tumor cells. Despite the importance of FAP in cancer, the mechanisms that govern ...
