Gastric Cancer (GC) is the second most common cancer in the world and a leading cause of cancer-related mortality. Methylation of promoter CpG islands (CGIs) belonging to tumor suppressor genes causes transcriptional silencing of their corresponding genes leading to carcinogenesis and other disorders. Adenomatous Polyposis Coli (APC) a tumor suppressor gene is inactivated by methylation of prom...

desmoids tumors, characterized by monoclonal proliferation of myofibroblasts, could occur in 5-10% of patients with familial adenomatous polyposis (fap) as an extra-colonic manifestation of the disease. fap can develop when there is a germ-line mutation in the adenomatous polyposis coli gene. although mild or attenuated fap may follow mutations in 5΄ extreme of the gene, it is more likely that ...

objective: colorectal cancer (crc) is one of the most common and aggressive cancers worldwide. the majority of crc cases are sporadic that caused by somatic mutations. the adenomatous polyposis coli (apc; omim 611731) is a tumor suppressor gene of wnt pathway and is frequently mutated in crc cases. this study was designed to investigate the spectrum of apc gene mutations in iranian patients wit...

objectives: familial adenomatous polyposis (fap) is an autosomal dominant predisposition to colon cancer. this hereditary genetic disease is characterized by more than 100 adenomatous polyps in colon and rectum. additional features may include desmoids tumors, polyps in the upper gastrointestinal tract, osteomas and congenital hypertrophy of the retinal pigment epithelium (chrpe). a mutation in...

Familial adenomatous polyposis (FAP) is responsible for <1% of colorectal cancer (CRC) cases and is inherited as an autosomal dominant trait. Patients generally present hundreds to thousands of adenomas and develop colorectal cancer by age 35- 40 if left untreated. Here we report four patients with germline frameshift mutation (small deletion) at exon 15 of adenomatous polyposis coli (APC) tumo...

BACKGROUND The adenomatous polyposis coli (APC) gene is a tumor suppressor gene which is mutated in the hereditary disease, familial adenomatous polyposis (FAP). Somatic mutations of the APC gene have also been identified in the majority of sporadic colorectal carcinomas, and mutation of the APC gene appears to be an early step in the initiation of colon cancer. Loss of heterozygosity (LOH) of ...
