The analysis of gene expression in non-small cell lung cancer patients of TCGA bank revealed significant lower overall survival in patients bearing tumors with unbalanced level of Nrf2/KEAP1 and increased expression of Nrf2 target gene, thus showing the importance of glutathione and Nrf2 levels as biomarkers in cisplatin resistance in lung cancer” (172). The gene discussed is KEAP1; the disease is lung carcinoma.
