O6-methylguanine-DNA methyltransferase (MGMT) is a DNA repair enzyme involved in chemoresistance. We have shown that MGMT abundance is regulated by canonical Wingless (Wnt) signaling and that inhibition of Wnt signaling restores chemosensitivity in preclinical cancer models. These findings have direct therapeutic implications for the treatment of cancers with high MGMT expression.
