Epigenetic Metabolic Regulator

Epigenetic metabolic regulators are a class of molecules and mechanisms that integrate cellular metabolism with epigenetic regulation. These regulators are typically enzymes or cofactors whose activity links the cell’s metabolic state to modifications of chromatin (such as DNA methylation and histone modification), thereby influencing gene expression without altering the underlying DNA sequence. Key examples include histone acetyltransferases (utilizing Acetyl-CoA), DNA/histone methyltransferases (utilizing SAM), sirtuins (utilizing NAD+), and TET dioxygenases (utilizing α-KG). These regulators play crucial roles in developmental processes, adaptation to environmental cues, and disease states, including cancer and metabolic disorders. Understanding how metabolism controls epigenetics opens avenues for therapeutic interventions, such as targeting key metabolic nodes or dietary interventions to modulate disease-associated epigenetic states.
