CISD1 and neoplasm: As is shown in Figure 7D, CISD1 was significantly and positively correlated with immune cell infiltration in KIRC, KIPAN, PCPG, PRAD, KICH, OV, BRCA, PAAD, SKCM-P (primary SKCM), LIHC, BLCA, and HNSC, suggesting that CISD1 may play a role in facilitating an effective immune response against the tumor, and tumors with higher CISD1 expression might respond better to immunotherapies in these cancers.
