PCSK1 and nonpapillary renal cell carcinoma: As shown in Figure 2(h), it was ferroptotic inhibitors (Fer-1 and Lip-1) and iron chelators (DFO and CPX), instead of necroptotic (Nec-1), apoptotic (Z-VAD) or autophagic (CQ) inhibitors, that significantly prevented the miR-4735-3p mimic-mediated cell death of human ccRCC cell lines.
