Loss of imprinting in colorectal cancer
Loss of imprinting (LOI) has been implicated in the predisposition to certain colorectal cancers. Insulin-like growth factor II (IGF2) is an imprinted gene in which the maternal allele is normally silenced. In the January 16 Proceedings of the National Academy of Science, Nakagawa et al. describe the development of a fluorescence-based primer extension assay (SnuPE) to examine whether LOI is associated with allele-specific methylation in colorectal cancer samples (Proc Natl Acad Sci USA 2001,
