Overview
The discovery of DNA methylation as a key epigenetic mechanism has revolutionized our understanding of gene regulation and expression. Epigenetics, the study of heritable changes in gene function that occur without a change in the underlying DNA sequence, has been a rapidly evolving field since the 1990s. The identification of DNA methylation as a crucial epigenetic mechanism has significant implications for our understanding of development, disease, and inheritance. For instance, studies have shown that DNA methylation plays a critical role in X-chromosome inactivation, genomic imprinting, and the suppression of transposable elements. The interplay between DNA methylation and other epigenetic mechanisms, such as histone modification and non-coding RNA regulation, is an active area of research. As our understanding of epigenetics and DNA methylation continues to grow, we may uncover new avenues for the diagnosis, treatment, and prevention of diseases, with a potential impact on over 100 million people worldwide affected by epigenetic disorders.
