Abstract:
Silencing of genes by aberrant promoter hypermethylation is now recognized as a crucial component in cancer initiation and progression. Highly sensitive assays have been developed to assess gene-promoter methylation in biological fluids. The detection of methylated genes in sputum could lead to the development of a screening test to non-invasively identify early cancer in high-risk people.

Epigenetic Regulation
Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
Epigenetic Regulation
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
