Differential methylation between normal fallopian tube controls and primary high-grade serous ovarian cancer. (A) Heat map clustering of methylation probes interrogating known genes for primary HGSOC and normal fallopian tubes in UIHC cohort. Each column represents a patient sample and each row represents a probe interrogating CpG sites of known genes categorized by Illumina. (B) Kyoto Encyclopedia of Genes and Genomes (KEGG) Pathways significantly enriched by genes that are differentially methylated between primary HGSOC and normal fallopian tube controls. (C) Experimental design showing how differentially methylated probes between HGSOC and fallopian tube controls were evaluated for gene expression. Initial analyses focused on inverse correlations between methylation status (hypermethylated or hypomethylated) and gene expression.
