Description
We here show that loss of imprinting (LOI) of IGF2 is a frequent and early event in the development of colon cancer and occurs throughout the large intestine. LOI leads to AKT1-dependent activation and suppression of a defined set of genes, many of which are cell cycle related. Our results further showed that IGF2 induces non-canonical wnt signaling. We hypothesize that IGF2 and Wnt5a cooperate in cancer progression. LOI is an attractive target for tumor prevention or targeted therapy.
