Meningiomas exhibit loss of heterozygosity of the APC gene [PDF]

Journal of Neuro-Oncology, 2007
The molecular mechanisms and candidate genes involved in development of meningiomas still need investigation and elucidation. In the present study 33 meningiomas were analyzed regarding genetic changes of tumor suppressor gene Adenomatous polyposis coli (APC), a component of the wnt signaling.

Somatic mutations of the APC gene in colorectal tumors: mutation cluster region in the APC gene [PDF]

Human Molecular Genetics, 1992
We examined somatic mutations of the adenomatous polyposis coli (APC) gene in 63 colorectal tumors (16 adenomas and 47 carcinomas) developed in familial adenomatous polyposis (FAP) and non-FAP patients. In addition to loss of heterozygosity (LOH) at the APC locus in 30 tumors, 43 other somatic mutations were detected.

p53 and APC gene mutations: software and databases [PDF]

Nucleic Acids Research, 1997
A large number of different mutations in the APC and p53 tumor suppressor genes have been identified in various types of cancer. This substantial increase since our previous reports can enable analyses which were not previously possible. In order to capture all these new data, the software permitting analysis has been improved.

Case Report: Coinheritance of Germline Mutations in APC and BRCA1 in Colorectal Cancer

Frontiers in Oncology, 2021
Deleterious mutations in APC gene cause the autosomal dominant familial adenomatous polyposis (FAP) which is typically characterized by the occurrence of hundreds to thousands of colorectal adenomas that eventually lead to colorectal cancers (CRCs ...

Analysis of hypermethylation and expression profiles of APC and ATM genes in patients with oral squamous cell carcinoma

Clinical Epigenetics, 2011
Background Adenomatous polyposis coli (APC) and Ataxia-telangiectasia-mutated (ATM) gene products have an important role in cell cycle control and maintenance of genomic stability.

Mutational analysis of driver genes defines the colorectal adenoma: in situ carcinoma transition

Scientific Reports, 2022
A large proportion of colorectal carcinomas (CRC) evolve from colorectal adenomas. However, not all individuals with colonic adenomas have a risk of CRC substantially higher than those of the general population.

Promoter hypermethylation of p16 and APC in gastrointestinal cancer patients

The Turkish Journal of Gastroenterology, 2014
Background/Aims: Cancer is a consequence of the disruption of cellular regulation. Epigenetic is one of the reasons of this disruption. Epigenetic factors play a role in the carcinogenesis by affecting proto-oncogenes and tumor suppressor genes and it is

Somatic Mutation Rate of the APC Gene [PDF]

Japanese Journal of Clinical Oncology, 2001
Somatic inactivation of the wild-type APC gene is involved in the development of adenoma of familial adenomatous polyposis. This situation is also true in sporadic adenomas. It is of biological interest to know the somatic mutation rate of the APC gene.The number of stem cells of the colon (N) and somatic mutation rate of the APC gene in a stem cell in

APC Gene Mutations in Human Prostate Cancer [PDF]

Japanese Journal of Clinical Oncology, 1996
Prostate cancer is the most common cancer in aged men. Although ras and p53 gene mutations have been detected in some prostate cancers, the major genetic alterations involved in its carcinogenesis are not well understood. Mutation of the APC gene is responsible for colorectal tumors in which ras and p53 mutations are also often involved. Using PCR-SSCP

PETALS: Proteomic Evaluation and Topological Analysis of a mutated Locus' Signaling

BMC Bioinformatics, 2010
Background Colon cancer is driven by mutations in a number of genes, the most notorious of which is Apc. Though much of Apc's signaling has been mechanistically identified over the years, it is not always clear which functions or interactions are ...
