Abstract

Osteoclasts are required for bone resorption. A new study in mice indicates that osteoclast differentiation is stabilized by DNA methylation at <i>Irf8</i> (encoding interferon regulatory factor 8) mediated by DNA methyltransferase 3a (Dnmt3a), which suppresses <i>Irf8</i> gene expression. The activity of Dnmt3 in osteoclasts requires elevated oxidative metabolism.
