Additionally, expression levels of DNA methylation analyses revealed that cg14152613 and cg19422565 of FABP4; cg06842886 and cg16126291 of ADIPOQ; cg04632671, cg06573644, cg27095527, cg18537222, cg25929976, and cg16827534 of PPARG; cg11270806 and cg27461259 of PPARGC1A; cg26138637 and cg18508525 of CD36; and cg04818078 and cg05194552 of CREBBP had the highest levels of DNA methylation and strong predictive value in patients with breast cancer (Supplementary Table 4). Here, PPARGC1A is linked to breast cancer.
