Figure 6. The correlation of Nrf2, PRDX5 and NQO1 mRNA expression in NSCLC specimens. (A) Nrf2, PRDX5 and NQO1 mRNA expressions in both tumor tissues and the adjacent normal tissues (**P < 0.01, compared with the adjacent normal tissues). (B) Statistical correlations among Nrf2, PRDX5 and NQO1 expressions in NSCLC samples. (C) Statistical correlations among Nrf2, PRDX5 and NQO1 expressions in NSCLC patients with Clinical TNM stage III-IV.
