Epigenetic Modifications: Therapeutic Potential in Cancer
نویسندگان
چکیده
Epigenetic modifications and alterations in chromatin structure and function contribute to the cumulative changes observed as normal cells undergo malignant transformation. These modifications and enzymes (DNA methyltransferases, histone deacetylases, histone methyltransferases, and demethylases) related to them have been deeply studied to develop new drugs, epigenome-targeted therapies and new diagnostic tools. Epigenetic modifiers aim to restore normal epigenetic modification patterns through the inhibition of epigenetic modifier enzymes. Four of them (azacitidine, decitabine, vorinostat and romidepsin) are approved by the U.S. Food and Drug Administration. This article provides an overview about the known functional roles of epigenetic enzymes in cancer development.

Introduction: Epigenetics involves the study of heritable changes in the regulation of gene activity and expression that are not dependent on gene sequence. Main mechanisms of epigenetic modifications are DNA methylation, Histone modification and Nucleosome positioning. Several studies have shown that these modifications are related to cancer initiation, progression or tumor metastasis. In cont...

متن کاملThe importance of epigenetic modifications in cancer progression
Epigenetics are dynamic and inherited changes in the genome that occur independently of DNA sequencing. This phenomenon requires coherent interaction with various enzymes and other molecular components. Abnormal epigenetic changes can lead to the onset of improper gene expression and the promotion of tumorigenesis. Because epigenetic changes are prone to external and reversible factors, they ar...

Both genetic and epigenetic changes are effective in cancer incidence and development. . .Epigenetic processes are alternations of DNA and histones conformations, chromatin remodeling, DNA methylation, post-translational modifications of histones and microRNAs patterns which are associated with genes expression or inhibition of them in cells. Some of reversible epigenetic changes such as DNA an...

Introduction: Epigenetic mechanisms regulate expression of the genome to generate various cell types during development or coordinate cellular responses to external stimulus. While epigenetics is of fundamental importance in eukaryotes, it plays a different role in bacteria. This article uncovers the most important recent data on how bacteria can alter epigenetic marks and can also contribute t...

The five leading causes of cancer-related deaths are lung (1,760,000 deaths), colorectal (862,000 deaths), stomach (783,000 deaths), liver (782,000 deaths), and breast (627,000 deaths) cancers. Epigenetic changes can alter chromatin compaction, leading to the regulation of geneexpression without changing the primary DNA sequence.Epigenetic mechanisms are normally involved incellular processes s...
