To identify potential miRNAs that regulate RSF1 in ESCC, we searched four miRNA prediction databases (Target Scan, Starbase, Tarbase, and miRDB) and identified miR-193b-3p, which was predicated by all four databases, as well as miR-27b-3p, miR-520f-3p, and miR-1271-5p, that were predicted from three databases (Figure 2A). The gene discussed is RSF1; the disease is esophageal squamous cell carcinoma.
