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. Here, CD274 is linked to melanoma.
