Fig. 5

Correlation of gene expression and DNA methylation. (a-b) Bar plots show correlation values between differentially expressed genes and promoter DNA methylation levels in male (a) and female (b) offspring. Genes that are negatively correlated and p-value < 0.05 are listed in the plots. (c-d) Scatter plots show the correlation between gene expression and promoter DNA methylation levels of individual genes in male (c) and female (d) offspring. Green colors (•) represent samples from control offspring and black colors (•) represent samples from e-cig-exposed offspring.
