The RNA-seq data analysis from different databases (TCGA and GEO database) showed the association of high expression of VEGFR2 with worse prognosis of the cancer patients (Figures 1(a) and 1(b)), while VEGFR2 was found to have significantly higher expression in tumor than the normal tissues (Figure 1(c), P < 0.05). The gene discussed is KDR; the disease is cancer.
