CISD1 and cancer: ,41 Since BRCA, KICH, LIHC, LUAD, and THYM all showed higher mRNA expression levels of CISD1, high stemness signatures, and high levels of RNA modifications with worse patient survival from the results above, we wondered if there are overlapping CISD1 coexpression genes in these cancers, and if these genes are potentially involved in fundamental processes related to CISD1 in cancers.
