Spearman’s correlation analysis for the mRNA expression of NRF2 pathway genes in normal and tumor tissues from our institutional cohort also revealed high concordance in expression between DPP3 and NRF2 pathway genes, including NFE2L2, KEAP1, and NQO1 (Figure 5E) in tumors, but not in normal tissues. The gene discussed is KEAP1; the disease is neoplasm.
