Figure 2.
Functional analysis of MAOA promoter/exon I/intron I DNA methylation using luciferase-based reporter gene assays. Left: Normalized reporter gene activity was significantly decreased in the presence of pCpGfree-promoter Lucia_MAOA vectors containing the methylated insert spanning CpGs 1–13 compared with those carrying a nonmethylated insert; ***P < .001. Right: No significant difference in normalized reporter gene activity was discerned between methylated or non-methylated pCpGfree-promoter Lucia control vectors lacking the insert of the sequence spanning CpGs 1–13.
