CD274 and renal carcinoma: Similar to the Kaplan–Meier survival analysis of CD274/PDCD1-correlated genes (Table 2 and Table 3), many of the microRNAs showed an opposite effect on survival for renal cancer patients compared to other cancer types, e.g., high expression of hsa-miR-142-5p was beneficial in cervical cancer, head and neck cancer, melanoma, and lung cancer, but low expression of the same microRNA was beneficial in renal cancer.
