Odds ratios for estrogen receptor positive breast cancer risk associated with lack of DNA methylation.

Only the estrogen receptor regulated genes (NUP155 and ZNF217) predicted the estrogen receptor positive breast cancer, which fits with the general hypothesis that estrogen exposure is associated to breast cancer risk. The data is adjusted for age alone or for age and family history of breast cancer.ERT = estrogen receptor-α target; DMHR = differently methylated depending on hormone receptor status; PCGT = stem cell polycomb group target; MBC = methylated in breast cancer; ER = estrogen receptor; OR = odds ratio; CI = confidence interval; * indicates P-values <0.05.
