These five m7G-related prognostic lncRNAs were KRT7-AS, USP30-AS1, ZFHX4-AS1, ACAP2-IT1, and TWSG1-DT, among which KRT7-AS, ZFHX4-AS1, and ACAP2-IT1 were risk factors for ovarian cancer (HR > 1), while USP30-AS1, and TWSG1-DT were protective factors (HR < 1), and Sankey diagrams more intuitively demonstrated the above results (Figure 2E). This evidence concerns the gene KRT7 and ovarian cancer.
