For PRDX2 (Figure 2B), its moderate expression in glandular cells was shown in all the three colon tissues while in tumor cells, its strong expression was shown in six of the seven COAD tissues (Likelihood Ratio = 7.719, p=0.005), consistent with it up-regulation in COAD in mRNA level in above analyses. Here, PRDX2 is linked to neoplasm.
