Formaldehyde regulates one-carbon metabolism and epigenetics

Recently, Pham et al. used an array of model systems to uncover a role for the enzyme methionine adenosyltransferase (MAT) -1A, which is mainly expressed in liver, in both sensing formaldehyde and regulating transcriptional responses that protect against it. This provides a new lens for understanding the effects of formaldehyde on gene regulation.
