Seventeen microRNAs showed high expression levels in 90% of all tumour samples (CPM > 1) and most (16 microRNAs) were significantly negatively correlated to DUSP2 mRNA expression in respective cancer types which could indicate a microRNA-induced mRNA degradation (p < 0.05, Fig. 1C, Tab S1) [40]. This evidence concerns the gene DUSP2 and neoplasm.
