In this study, 27 genes were chosen based on their differential expression in at least seven out of eight distinct carcinoma types analyzed (ANGPTL1, GSTM5, IQGAP3, UHRF1, CCBE1, MYBL2, CHRDL1, PKMYT1, ABCA8, CTHRC1, PKNOX2, UBE2C, DES, RELN, ADH1B, MT1M, CDT1, FAM111B, SFRP1, C7, GHR, LYVE1, IGSF10, MFAP4, RNF150, and HBB). This evidence concerns the gene PKNOX2 and carcinoma.
