摘要

Relaxation of imprinting at the insulin-like growth factor II (IFG-II)/H19 locus is a major mechanism involved in the onset of sporadic Wilms tumor and several other embryonal tumors. The high prevalence of histologically abnormal foci in kidney adjacent to Wilms tumors suggests that tumor-predisposing genetic/epigenetic lesion might also be found at high frequency in Wilms tumor-bearing kidneys. Focusing on Wilms tumors with relaxation of IFG-II imprint- ing, we determined the frequency of epigenetic change at the IFG-II/H19 locus in adjacent kidney.
