BACH1 and neoplasm: Figure 2 presents the correlations of mRNA levels between the tumor and normal tissues, which were significant in Nrf2, Keap1, and Hmox1, but not in Bach1.  Figure 3 shows the correlations of mRNA levels in the normal and tumor tissues with or without detectable Bach1 mRNA expression. The Nrf2 mRNA level lost significant correlations with those of Keap1 and Hmox1 in the tumor tissue of subjects without detectable Bach1 mRNA expression.  Figure 4 presents the correlations of mRNA levels in the normal and tumor tissues with and without distant metastasis.
