Furthermore, miRNAs (miR-125a-5p, miR-331–3p, miR-17, miR-150, miR-155, miR-27b, miR-31, miR-92a and miR-509–5p), which differentially expressed in gastric cancer, were found to regulate expression of E2F1, E2F2, E2F5 and E2F7 in this study (S3 Table). This evidence concerns the gene E2F7 and gastric cancer.
