The Role of Methylation in Gene Expression and Complex Human Diseases

Methylation seems to change how histone proteins as well as certain transposable elements bind with DNA, which in turn affects how genes are expressed. Despite methylation levels in cell lines are extremely stable; the young embryo is distinguished by significant changes in DNA methylation. This epigenetic change of the chromosome known as DNA imprinting is essential for controlling numerous cellular activities. Which include transcriptional, histone modifications, the suppression of the X chromosome, molecular imprinted or chromosomal integrity. In line with these crucial responsibilities, it has been discovered that abnormal Methylation is linked to an increasing variety of biological disorders. Understanding these disorders has revealed fundamental new truths about how DNA methylation as well as other epigenetic modifications affects physiological equilibrium or growth. Although the significance of epigenetics was first understood in relation to its function in cellular differentiation, overwhelming evidence has demonstrated that it also performs a significant role in the onset or progression of several prevalent illnesses. They address some new research on the role of Methylation, a key regulatory alteration, in a number of prevalent disorders. Population-based environmental epidemiology research upon that involvement underlying epigenetic mechanisms in prevalent illnesses have revealed a number of additional risk variables, but this comparatively young area still confronts several particular difficulties. In this article, they outline the possibilities but special difficulties that genetic epidemiology investigations provide, as well as several possible answers.
