The number of differentially expressed genes with altered DNA methylation following TiO2-NP exposure.—Venn diagram analysis whether differentially expressed genes are accompanied by alteration of DNA methylation. Venn diagram showing the number of differentially expressed genes with altered DNA methylation following TiO2-NP (Sham vs. TiO2-H) in the brains of 1-day-old offspring mice [(A): male, (B): female]. The DNA methylation state and expression level of genes were identified by Mouse CpG Island Microarray and SurePrint G3 Mouse GE 8 × 60 K Microarray, respectively.
