Figure 7From: Target gene expression levels and competition between transfected and endogenous microRNAs are strong confounding factors in microRNA high-throughput experimentsCpG-rich genes, non-developmental genes, and housekeeping genes appear to be strong miRNA targets in microarray experiments. We subdivided all RefSeq genes into sub-groups based on three different features: CpG frequency (CpG), and whether the genes were developmental (Dev) and housekeeping (HK) genes (see Methods).
