We have determined the methylation status of the CpG island of the oestrogen receptor gene in seven human ovarian cell lines. Cell lines expressing oestrogen receptor showed no evidence of hypermethylation. In three of four cell lines that produced no detectable oestrogen receptor protein, hypermethylation was observed at the NotI site of the CpG island. These results indicate that aberrant hypermethylation may be responsible for a significant proportion of epithelial ovarian tumours in which oestrogen receptor expression is lost.
