Snezhkina et al. performed comprehensive analysis on the data presented in The Cancer Genome Atlas (TCGA) and five miRNA–mRNA target interaction databases (TargetScan, DIANA microT, mirSVR (miRanda), PicTar and miRTarBase) to look for potential miRNAs that may inhibit HK2 expression in CRC [33]. The gene discussed is HK2; the disease is colorectal carcinoma.
