We also assessed protein expression levels of ERCC6 and ERCC8 in breast cancer using the Broad Institute proteome database (https://prot-shiny-vm.broadinstitute.org:3838/CPTAC-BRCA2016/) and found elevated expression of both, similar to some of our other comparison proteins such as CHEK2 (Data not shown). This evidence concerns the gene ERCC6 and breast carcinoma.
