CISD2 and hepatocellular carcinoma: The function of NRAV is related to immune checkpoints,[30] ferroptosis,[31] and activation of Wnt/β-catenin signaling through regulation of the miR-199a-3p/CISD2 axis,[32] implying that NRAV may participate not only in copoptosis but also in activating other signaling pathways to perform its function in the tumorigenesis of HCC.
