Figure 1.
Identification of differences in DNA methylation between psoriasis and controls. Scatter plot between methylation changes (delta-beta, psoriasis PRE-UV vs. controls) and corresponding −log10(false-discovery rate (FDR) adj. P-value) for total assessed 470,903 sites was shown. CpG sites with delta-beta>0.2 and −log10(FDR adj. P-value)>2 were defined as methylation variable positions (MVPs). The upper square indicates hypermethylated MVPs, and the bottom square indicates hypomethylated MVPs in psoriasis compared with controls.
