abstract = {DNA methylation changes in peripheral blood DNA have been
shown to be associated with solid tumors. We sought to
identify methylation alterations in whole blood DNA that are
associated with breast cancer (BC). Epigenome-wide DNA
methylation profiling on blood DNA from BC cases and healthy
controls was performed by applying Infinium
HumanMethylation450K BeadChips. Promising CpG sites were
selected and validated in three independent larger sample
cohorts via MassARRAY EpiTyper assays. CpG sites located in
three genes (cg06418238 in RPTOR, cg00736299 in MGRN1 and
cg27466532 in RAPSN), which showed significant
hypomethylation in BC patients compared to healthy controls
in the discovery cohort (p < 1.00 x 10-6) were selected and
successfully validated in three independent cohorts
(validation I, n =211; validation II, n=378; validation III,
n=520). The observed methylation differences are likely not
cell-type specific, as the differences were only seen in
whole blood, but not in specific sub cell-types of
leucocytes. Moreover, we observed in quartile analysis that
women in the lower methylation quartiles of these three loci
had higher ORs than women in the higher quartiles. The
combined AUC of three loci was 0.79 $(95\%CI$ 0.73-0.85) in
validation cohort I, and was 0.60 $(95\%CI$ 0.54-0.66) and
0.62 $(95\%CI$ 0.57-0.67) in validation cohort II and III,
respectively. Our study suggests that hypomethylation of CpG
sites in RPTOR, MGRN1 and RAPSN in blood is associated with
BC and might serve as blood-based marker supplements for BC
if these could be verified in prospective studies.},
