Summary of "Epigenetic-based therapies in cancer: progress to date."

Epigenetic gene silencing is a hallmark of cancer cells. Two important types of epigenetic changes are DNA methylation and histone modification. These modifications are catalysed by DNA methyltransferases (DNMTs) and histone deacetylases (HDACs), resulting in chromatin structure changes and gene inactivation. Interestingly, inhibition of these enzymes is known to induce differentiation or apoptosis of cancer cells. Therefore, DNMTs and HDACs have become attractive therapeutic targets. In recent years, many different DNMT and HDAC inhibitors have been developed, and multiple molecular mechanisms through which these agents exert anti-cancer effects have been identified. While a large number of clinical trials are ongoing, hypomethylating agents and HDAC inhibitors seem to be promising for treating several types of cancer. Moreover, developing effective strategies of combining epigenetic therapy with conventional chemotherapy will be one of the major challenges in the future. We briefly review current advances in epigenetic therapies with a focus on recently reported clinical trials.

Medical and Biotech [MESH] Definitions

A cancer registry mandated under the National Cancer Act of 1971 to operate and maintain a population-based cancer reporting system, reporting periodically estimates of cancer incidence and mortality in the United States. The Surveillance, Epidemiology, and End Results (SEER) Program is a continuing project of the National Cancer Institute of the National Institutes of Health. Among its goals, in addition to assembling and reporting cancer statistics, are the monitoring of annual cancer incident trends and the promoting of studies designed to identify factors amenable to cancer control interventions. (From National Cancer Institute, NIH Publication No. 91-3074, October 1990)

Therapies using arts or directed at the senses.

A performance measure for rating the ability of a person to perform usual activities, evaluating a patient's progress after a therapeutic procedure, and determining a patient's suitability for therapy. It is used most commonly in the prognosis of cancer therapy, usually after chemotherapy and customarily administered before and after therapy. It was named for Dr. David A. Karnofsky, an American specialist in cancer chemotherapy.
