MEG3 and cervical carcinoma: We revealed that the MEG3 promoter is hypermethylated in cervical cancer cells, and that demethylation of the promoter resulted in re-expression of MEG3. More importantly, as the promoter methylation level decreased, the expression of MEG3 increased in cervical cancer cells, which indicated that loss of MEG3 expression in cervical cancer cells was the result of promoter hypermethylation, at least in part.
