MRC1 and cancer: These results highlight some very significant fold changes in specific MMRs, providing fertile ground for future works, and they are summarized in Figure 3, where we present the top two upregulated and downregulated MMRs per cancer type, with the exception of TCGA-THYM, in which we found no upregulation of MMRs, and TCGA-SARC along with TCGA-PAAD, in which we found only one upregulated MMR.
