Comprehensive DNA Methylation Review: Mechanisms, Health Implications, and Research Insights

DNA methylation stands at the forefront of epigenetic research, offering profound insights into how environmental and genetic factors shape health and disease. This comprehensive DNA methylation review examines the latest scientific findings on its role in cellular function, aging, and disease progression.

DNA Methylation Review: Core Mechanisms and Biological Role

DNA methylation involves the addition of a methyl group to cytosine bases in DNA, primarily at CpG sites, regulating gene expression without altering the DNA sequence. This epigenetic modification influences chromatin structure, silencing genes or modulating their activity. The DNA methylation review details key enzymes like DNA methyltransferases (DNMTs), demethylases, and proteins involved in maintaining methylation patterns, highlighting their critical roles in development and cellular identity.
