Negative correlations were observed between CD74 and MMR-related genes in many cancer types, including BRCA, CESC, GBM, LUAD, LUSC, OV, SARC, TGCT, THCA, THYM, and UCEC (Fig. 4A), as well as with the HRR signature in ACC, GBM, LUSC, SARC, and THYM (Fig. 4B) and with stemness in UCS, LUSC, HNSC, and ESCA (Fig. 4C). This evidence concerns the gene MRC1 and cancer.
