Familial adenomatous polyposis (FAP) is an autosomal dominant inherited disease characterized by the development of hundreds to thousands of adenomatous polyps in colon and rectum. The APC gene (adenomatous polyposis coli) is considered as the major mutated gene in FAP. It has been shown that biallelic germline mutations in the base-excision-repair gene MYH can be responsible for a recessive in...

Mutations in the adenomatous polyposis coli (APC) gene are responsible for familial adenomatous polyposis coli and also sporadic colorectal cancer development. By using antibodies raised against the N-terminal region of APC protein, we have detected the variable masses of endogenous APC proteins in individual cell lines established from human colorectal carcinomas caused by nonsense mutations o...

The APC gene at human chromosome 5q21 is responsible for familial adenomatous polyposis coli. Furthermore, sporadic cancers of not only colon but also other digestive organs often contain mutations in the APC gene. A dominant mouse mutation Min that was generated by chemical mutagenesis and causes polyposis in the digestive tract is in the mouse homologue of the human APC gene. The APC mRNA is ...

The adenomatous polyposis coli (APC) tumor suppressor protein is inactivated by mutations in the majority of colorectal cancers. A recent study has revealed that alterations in the APC signaling pathway can result in the transcriptional activation of the c-MYC gene.

Background and Aim. Germline mutations of the adenomatous polyposis coli (APC) gene cause familial adenomatous polyposis (FAP), an autosomal dominant inherited disease mainly characterized by colorectal adenomatous polyposis. Genetic studies of FAP have shown that somatic APC mutations are dependent on the position of the germline APC mutation. However, the molecular mechanism underlying these ...

Mutation of tumor suppressor gene adenomatous polyposis coli (APC) is an initiating step in most colon cancers. This review summarizes Apc models in mice and rats, with particular concentration on those most recently developed, phenotypic variation among different models, and genotype/phenotype correlations.

Adrenal hemangioma is an uncommon benign vascular tumor that is often discovered incidentally. It has never been reported in association with familial adenomatous polyposis. We report a case of a 60-year old man with a history of familial adenomatous polyposis, in whom a huge retroperitoneal cyst of 18x17 cm was discovered during routine radiologic evaluation. Because of the impossibility of ru...

Adenomatous polyposis coli (APC) protein has been thought to function as a tumor suppressor through its involvement in the Wnt/beta-catenin signaling pathway. However, its connections to the cytoskeleton and microtubules in particular are becoming apparent, and the discovery of these new functions for APC is leading to a reevaluation of its role not only in tumorigenesis, but also in normal phy...

Colon cancer frequently results from mutations that constitutively activate the Wnt signaling pathway, a major target being the tumor suppressor gene adenomatous polyposis coli (APC). We recently identified the transcription factor RIP140 as a new inducer of APC gene transcription that inhibits colon cancer cell growth and impedes the Wnt signaling pathway by reducing β-catenin activation.
