RNASEK and cancer: According to the KM database, our results revealed a correlation between high RNASEK expression and good prognosis in five types of cancers: BLCA (HR: 0.57, P = 0.002), cervical squamous cell carcinoma (CESC) (HR: 0.58, P = 0.021), KIRP (HR: 0.43, P = 0.013), ovarian cancer (OV) (HR: 0.64, P = 0.005), sarcoma (SARC) (HR: 0.55, P = 0.019) (Appendix D) and PAAD (HR: 0.45, P = 0.0001) (Figure 5B).
