Motif search in promoter region of correlated genes show enrichment for CG-rich motifs. a Motifs enriched in significantly methylation/expression correlated 1 kb upstream of the TSS compared to non-correlated genes. b Average number of CpG-islands present in 1 kb upstream from the promoter in both groups compared to number of promoters in each groups. c Boxplots to the right show the GC frequency of the significantly and non-significantly correlated genes. μ represents the mean for each group. p-value was calculated using the Students’ t-test
