Low expression of RORα and high expression of ECM1 were also closely associated with poor OS and PFS in all ovarian cancer patients (Figure 8D-E, Supplementary Figure 3E, Supplementary Figure 4).The correlation between RORα, ECM1, VEGFR2, and clinical pathological features in ovarian cancer patients is shown in Supplementary Tables 1 and 2. The gene discussed is KDR; the disease is ovarian carcinoma.
