Abstract:
Epigenetic alterations, including aberrant DNA methylation, play an important role in human cancer development. Importantly, epigenetic alterations are reversible and can be targets for therapy or chemoprevention for various types of human cancers. A field for cancerization, or a field defect, is formed by the accumulation of genetic and/or epigenetic alterations in normal-appearing tissues and can correlate with risk of cancer development. Thus, a better understanding of epigenetic field cancerization may represent a useful translational opportunity for cancer risk assessment, including previous history and exposure to carcinogenic factors, and for cancer prevention. In this article, we summarize current knowledge regarding epigenetic field cancerization and its clinical implications in gastrointestinal cancers, including colorectal cancer, gastric cancer and esophageal cancer.

Cancer-Critical Genes II: Tumor Suppressor Genes
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...
