High levels of NRF2 expression correlate with poor prognosis in lung tumor,15 gallbladder tumor,16 and diffuse large B-cell lymphoma.17 Here, we confirmed that NRF2 staining was concentrated in the nucleoplasm, and its expression was upregulated in GC compared to paracancerous tissues. The gene discussed is NFE2L2; the disease is diffuse large B-cell lymphoma.
