Abstract We report that CpG island methylation, an epigenetic modification of DNA known to correlate closely with silencing of gene transcription, appears in the oestrogen receptor (ER) gene in a subpopulation of cells which increases as a direct function of age in human colonic mucosa. This same methylation change characterizes virtually all cells in all 45 colorectal tumours examined, including the earliest stages of tumour formation. ER gene expression is diminished or absent in colorectal tumours, and introduction of an exogenous ER gene in cultured colon carcinoma cells resulted in marked growth suppression. Our data suggest that methylation associated inactivation of the ER gene in ageing colorectal mucosa could be one of the earliest events that predispose to sporadic colorectal tumorigenesis.
