We selected the NAD(P) H gene of quinone oxidoreductase 1 (NQO1), as the induction of NQO1 gene expression occurs through the Nrf2-Keap1/ARE pathway.

Triptolide (50-100 nM) is able to decrease mitochondrial respiration and increase ROS and apoptosis in p53-deficient non-small-cell lung cancer and consequently to upregulate Nrf2 and its target gene HO-1 and NQO1 [10].

In the MA sensitizer chemical group, KEAP1 and NRF2 were found as key hubs as well as their target genes NQO1 and HMOX1 (Ade et al., 2009; Natsch, 2010) and AHR (Schulz et al., 2013; Kohle and Bock, 2007).
As shown in Figure 3A, 1 [micro]M DL-Sulforaphane significantly induced the expression of NQO1 and SPP1 expression.
Garg and Maru [78] indicated that curcumin increased ARE-binding of Nrf2 and induced the activity as well as expression of GST and NQO1 and their mRNA transcripts; additionally, the liver and lung of mice treated with dietary curcumin had reduced oxidative stress.
The activated Nrf2 protein then binds antioxidant-responsive elements within the promoter regions of the antioxidant genes and induces transcription of a series of antioxidant enzymes, including NADPH quinone oxidoreductase (NQO1), glutathione-S-transferase (GSH), heme oxygenase1 (HO-1), and [gamma]-glutamylcysteine synthetase [18, 21-23] (Figure 1).
Specific primers for heme oxygenase (decycling) 1 (HO-1), NAD(P)H dehydrogenase [quinone] 1 (NQO1), glutamatecysteine ligase catalytic subunit (GCLC), glutamate-cysteine ligase regulatory subunit (GCLM), and nuclear factor (erythroid-derived 2)-like 2/NF E2-related factor (Nrf2) were designed, as well as primers for several housekeeping genes (see Supplementary Table 1 available online at https://doi.
In addition, cinnamaldehyde, an important flavor component in cinnamon essential oil upregulated Nrf2 expression, stimulated its translocation to the nucleus, and increased HO-1, NQO1, CAT, and GPx1 expression under high glucose conditions [7].
