Changes in DNA methylation in nontarget tissues, specifically peripheral blood, can also affect risk of malignant disease. We sought to identify specific profiles of DNA methylation in peripheral blood that are associated with bladder cancer risk and therefore serve as an epigenetic marker of disease susceptibility. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p> We performed genome-wide DNA methylation profiling on participants involved in a population-based incident case-control study of bladder cancer. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> In a training set of 112 cases and 118 controls, we identified a panel of 9 CpG loci whose profile of DNA methylation was significantly associated with bladder cancer in a masked, independent testing series of 111 cases and 119 controls (P &lt; .0001). Membership in three of the most methylated classes was associated with a 5.2-fold increased risk of bladder cancer (95% CI, 2.8 to 9.7), and a model that included the methylation classification, participant age, sex, smoking status, and family history of bladder cancer was a significant predictor of bladder cancer (area under the curve, 0.76; 95% CI, 0.70 to 0.82). CpG loci associated with bladder cancer and aging had neighboring sequences enriched for transcription-factor binding sites related to immune modulation and forkhead family members. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p> These results indicate that profiles of epigenetic states in blood are associated with risk of bladder cancer and signal the potential utility of epigenetic profiles in peripheral blood as novel markers of susceptibility to this and other malignancies. <\/jats:p><\/jats:sec>","DOI":"10.1200\/jco.2010.31.3577","type":"journal-article","created":{"date-parts":[[2011,2,23]],"date-time":"2011-02-23T04:56:47Z","timestamp":1298437007000},"page":"1133-1139","source":"Crossref","is-referenced-by-count":116,"title":["DNA Methylation Array Analysis Identifies Profiles of Blood-Derived DNA Methylation Associated With Bladder Cancer"],"prefix":"10.1200","volume":"29","author":[{"given":"Carmen J.","family":"Marsit","sequence":"first","affiliation":[{"name":"From Brown University, Providence, RI; and Dartmouth Medical School, Lebanon, NH."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Devin C.","family":"Koestler","sequence":"additional","affiliation":[{"name":"From Brown University, Providence, RI; and Dartmouth Medical School, Lebanon, NH."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brock C.","family":"Christensen","sequence":"additional","affiliation":[{"name":"From Brown University, Providence, RI; and Dartmouth Medical School, Lebanon, NH."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margaret R.","family":"Karagas","sequence":"additional","affiliation":[{"name":"From Brown University, Providence, RI; and Dartmouth Medical School, Lebanon, NH."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.
