Epigenetic Signaling

Meaning

Epigenetic Signaling refers to the non-genetic, heritable changes in gene expression that do not involve alterations to the underlying DNA sequence, acting as a crucial regulatory layer controlling cellular identity and function. These signals, including DNA methylation and histone modification, determine which genes are turned on or off in specific cells, profoundly influencing development, health, and the aging process. Understanding this signaling is essential for modulating gene function without changing the core genetic code.
