Abstract:
The Adenomatous Polyposis Coli (APC) Gene is a tumor suppressor gene located in the chromosome 5q21. It has a sequence of 2843 amino acids and a weight of 312 kD. The mutation of the APC gene occurs at the early stages of most sporadic colorectal cancers; and up to 30% in familial adenomatous polyposis. The absence of APC will indicate the inadequate migration of colon mucous cells and its accumulation resulting in polyps formation, which determines a stage in carcinogenicity. An adequate study in prone groups may lead to chemoprophylaxis and/or early treatment of polyps.

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
