Epigenetic Regulation

Epigenetic regulation refers to the control of gene expression that occurs without altering the underlying DNA sequence. It involves chemical modifications to DNA, histone proteins, chromatin structure, and non-coding RNAs that collectively determine whether genes are turned on or off. Key mechanisms include DNA methylation, histone modifications, chromatin remodeling, and non-coding RNA-mediated regulation. Epigenetic regulation is essential for cell differentiation, maintenance of cellular identity, developmental programming, and response to environmental stimuli. It plays a role in disease states such as cancer, cardiovascular diseases, neurological disorders, and metabolic syndromes. Targeting epigenetic regulators has become a promising strategy in treating cancers and other diseases where abnormal epigenetics drive pathology.

Drugs targeting epigenetic regulators aim to reverse aberrant epigenetic modifications, restoring normal gene expression patterns. DNMT inhibitors reduce DNA methylation, while HDAC inhibitors increase histone acetylation.
