Loss of imprinting and cancer

Abstract excerpt

Imprinting is defined as the parental allele-specific expression of a very limited set of genes (about 50-80). This regulation depends upon an epigenetic marking of parental alleles during gametogenesis. Monoallelic expression ensures that the levels of the proteins encoded by imprinted genes, important factors of embryonic growth, placental growth or adult metabolism, are assured. Without precise control of...
