The threshold level of adenomatous polyposis coli protein for mouse intestinal tumorigenesis.
The adenomatous polyposis coli (APC) gene, whose mutations are responsible for familial adenomatous polyposis, is a major negative controller of the Wnt/beta-catenin pathway. To investigate the dose-dependent effects of APC protein in suppressing intestinal tumorigenesis, we constructed mutant mice carrying hypomorphic Apc alleles Apc(neoR) and Apc(neoF) whose expression levels were reduced to ...
متن کاملInvolvement of adenomatous polyposis coli in colorectal tumorigenesis.
Colorectal cancer arises after a series of mutations in various tumor suppressor and proto-oncogenes, each of which is accompanied by specific alterations and pathological conditions. Recent advances have contributed a great deal of understanding of the molecular basis of events that lead to colorectal tumorigenesis. Mutation in the adenomatous polyposis coli (APC) gene is considered to be one ...
متن کاملNuclear adenomatous polyposis coli suppresses colitis-associated tumorigenesis in mice.
Mutation of tumor suppressor adenomatous polyposis coli (APC) initiates most colorectal cancers and chronic colitis increases risk. APC is a nucleo-cytoplasmic shuttling protein, best known for antagonizing Wnt signaling by forming a cytoplasmic complex that marks β-catenin for degradation. Using our unique mouse model with compromised nuclear Apc import (Apc(mNLS)), we show that Apc(mNLS/mNLS)...
متن کاملApc1638T: a mouse model delineating critical domains of the adenomatous polyposis coli protein involved in tumorigenesis and development.
The adenomatous polyposis coli (APC) gene is considered as the true gatekeeper of colonic epithelial proliferation: It is mutated in the majority of colorectal tumors, and mutations occur at early stages of tumor development in mouse and man. These mutant proteins lack most of the seven 20-amino-acid repeats and all SAMP motifs that have been associated with down-regulation of intracellular bet...
متن کاملFamilial adenomatous polyposis coli.
The other mode of treating these patients are subtotal colectomy with ileorectal anastomosis alongwith regular follow up with proctoscopy for development of cancer in retained rectal mucosa(3,7). Recently, Stevan et al. (8) utilized laproscope for total proctocolectomy as well as ileoanal anostomosis while others performed ileopouch anal anastomosis alongwith total proctocolectomy(9,10). Thus t...
