As shown in Fig. 1J, higher E2F1/E2F7 mRNA ratios were correlated with poor prognosis, whereas higher E2F7/E2F1 mRNA ratios were correlated with good prognosis, further supporting the oncogenic role of E2F1 and the tumor suppressor role of E2F7 in GC. This evidence concerns the gene E2F7 and neoplasm.
