Transketolase (TK, EC 2.2.1.1) is the key rate-limiting enzyme of the non-oxidative branch of the pentose phosphate pathway of carbohydrate transformation. TKs (with the exception of the enzymes of mammalian origin) are characterized by broad substrate specificity. Xylulose 5-phosphate (X5P), fructose 6-phosphate (F6P), erythrulose 4-phosphate, and sedoheptulose 7-phosphate are typical donor substrates of TK; ribose 5-phosphate (R5P), glyceraldehyde 3-phosphate (G3P), and erythrose 4-phosphate are typical acceptor substrates. |

We identified six genes involved in the PPP and NADPH production pathways as direct targets of Nrf2. To identify the target genes of NRF2 responsible for cell proliferation, we performed microarray analysis in A549 cells treated with NRF2 siRNA or control siRNA. We used three independent NRF2 siRNAs and selected genes whose expression levels were reduced to less than 66.7% of that of the control sample by all three siRNAs to minimize off-target effects (Table S1). In addition to the typical target genes of NRF2 encoding detoxifying enzymes and antioxidant proteins (cytoprotective genes), genes whose products are involved in the PPP (glucose-6-phosphate dehydrogenase [G6PD], phosphogluconate dehydrogenase [PGD], transketolase [TKT], and transaldolase 1 [TALDO1]) and de novo nucleotide synthesis (phosphoribosyl pyrophosphate amidotransferase [PPAT] and methylenetetrahydrofolate dehydrogenase 2 [MTHFD2]) were decreased by the NRF2 knockdown (Figure 1B). Genes encoding enzymes for NADPH synthesis (malic enzyme 1 [ME1] and isocitrate dehydrogenase 1 [IDH1]) were also decreased (Figure 1B). We also confirmed the reduction of the enzyme proteins encoded by these genes in the NRF2-knockdown cells (Figure 1C). |
