Multiple intestinal neoplasia caused by a mutation in the murine homolog of the APC gene.

TLDR
In this paper, a mouse lineage that exhibits an autosomal dominantly inherited predisposition to multiple intestinal neoplasia (Min) was described and linkage analysis showed that the murine homolog of the APC gene (mApc) was tightly linked to the Min locus.
Abstract
Germ-line mutations of the APC gene are responsible for familial adenomatous polyposis (FAP), an autosomal dominantly inherited disease in humans. Patients with FAP develop multiple benign colorectal tumors. Recently, a mouse lineage that exhibits an autosomal dominantly inherited predisposition to multiple intestinal neoplasia (Min) was described. Linkage analysis showed that the murine homolog of the APC gene (mApc) was tightly linked to the Min locus. Sequence comparison of mApc between normal and Min-affected mice identified a nonsense mutation, which cosegregated with the Min phenotype. This mutation is analogous to those found in FAP kindreds and in sporadic colorectal cancers.

Wnt/beta-catenin signaling in development and disease.

TL;DR: A remarkable interdisciplinary effort has unraveled the WNT (Wingless and INT-1) signal transduction cascade over the last two decades, finding that Germline mutations in the Wnt pathway cause several hereditary diseases, and somatic mutations are associated with cancer of the intestine and a variety of other tissues.

Suppression of Intestinal Polyposis in ApcΔ716 Knockout Mice by Inhibition of Cyclooxygenase 2 (COX-2)

TL;DR: Results provide direct genetic evidence that COX-2 plays a key role in tumorigenesis and indicate that COx-2-selective inhibitors can be a novel class of therapeutic agents for colorectal polyposis and cancer.

Genetic alterations during colorectal-tumor development.

TL;DR: It is found that ras-gene mutations occurred in 58 percent of adenomas larger than 1 cm and in 47 percent of carcinomas, which are consistent with a model of colorectal tumorigenesis in which the steps required for the development of cancer often involve the mutational activation of an oncogene coupled with the loss of several genes that normally suppress tumors.

Mutations in the p53 gene occur in diverse human tumour types

TL;DR: It is suggested that most tumours with allelic deletions of chromosome 17p contain p53 point mutations resulting in amino-acid substitutions, and p53 gene mutations are clustered in four 'hot-spots' which exactly coincide with the four most highly conserved regions of the gene.
