The mitochondria provide the cell with energy from oxidative phosphorylation, which is intimately linked to the production of ROS. In addition, NFE2L2 transcription is regulated by several transcription factors, including aryl hydrocarbon receptor (AhR) [30] and nuclear factor (NF)-B [31]. Misfolded protein accumulation and aggregation induce excessive production of ROS from mitochondria, ER, and other sources, which can activate NRF2 [95,96].

NFE2L2 gene contains ARE within its promoter region that renders NRF2 the ability to directly activate its own transcription, providing a positive feedback mechanism to amplify NRF2 effects [29]. Ribose-5-phosphate is converted to 5-phospho-ribosyl-a-1-pyrophosphate (PRPP), which then is catalyzed by phosphoribosyl pyrophosphate amidotransferase (PPAT) to generate phosphoribosylamine (5PRA), a rate-limiting step in the de novo purine biosynthetic pathway.

Increased NRF2 expression in leukocytes such as macrophages inhibits the expression of pro-inflammatory genes through down-regulation of the NF-B pathway. NRF2 also alters iron homeostasis by increasing iron storage and its flux in and out of the cell. PubMed NRF2 activation decreases STING expression by destabilizing its mRNA, which leads to decreased type I IFN production, decreased antiviral cytosolic DNA sensing, and increased DNA virus infection in human cells, whereas the silencing of NRF2 decreases virus infectivity [133].

(2004) Transcriptional regulatory code of a eukaryotic genome. NRF2 also regulates de novo serine biosynthesis in cooperation with ATF4, leading to synthesis of serine-derived glycine and cysteine via the methionine cycle and one carbon metabolism [23,35,88]. A transcriptional activity assay of the AtBSD1 protein in yeast revealed that the AtBSD1 protein functions as a transcriptional activator, and the N-terminal region (1204 amino acids) of the AtBSD1 protein contains a transcriptional activation domain. Autophagy cargo-adaptor p62/sequestosome 1 (SQSTM1) [9,10,11], dipeptidyl peptidase 3 (DPP3) [12], Wilms tumor gene on X chromosome (WTX) [13], and Partner and Localizer of BRCA2 (PALB2) [14] all contain KEAP1-interacting region (KIR)-like ETGE motifs and thus competes with NRF2 for KEAP1 binding, resulting in KEAP1 sequestration and NRF2 stabilization. Since NRF2 was first discovered in 1994 as a member of the human CNC-bZIP transcription factor family for the transcriptional stimulation of beta-globin genes [69], over past few decades, many studies have revealed the major role of NRF2 as a transcription factor for antioxidant stress response and drug detoxification. Autophagy is a protein and organelle quality control mechanism that orderly degrades and recycles cellular components, including protein aggregates and old or damaged organelles. Nrf2 is controlled by two distinct beta-TrCP recognition motifs in its Neh6 domain, one of which can be modulated by GSK-3 activity. NRF2-mediated antioxidant defense in Treg cells leads to their expansion and survival. Interestingly, KEAP1-mediated NRF2 ubiquitination and degradation mainly act in the cytoplasm, whereas KEAP-1 independent NRF2 stability regulation is both cytoplasmic and nuclear, which contributes to termination of NRF2-mediated transcriptional response [20,22,23].

It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. When activated by ligands, such as TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin), AHR dimerizes with AHR nuclear translocator (ARNT) to bind to the XRE of NFE2L2 and activates NRF2 transcription [30].

Myeloid lineage-specific deletion of antioxidant system enhances tumor metastasis.
The Human Transcription Factors - PubMed Besides G6PD and PGD, malic enzyme (ME1) and isocitrate dehydrogenase (IDH1) also catalyze the production of NADPH [35,77]. Glutamate-cysteine ligase catalytic (GCLC) and modulator (GCLM) subunits as well as glutathione synthetase (GSS) are the three NRF2 targets involved in the GSH synthesis [23]. The key switch between the tumor suppressive role and tumor promoting roles of NRF2 could be due to the active NRF2 protein levels/doses and the duration of NRF2 activation in the crosstalk with specific factors and signaling pathways. The BTB domain homodimerizes with KEAP1 and contributes to the interaction of IVR with Cul3/RBX1 complex. The NRF2 homolog in C. elegans SKN-1 induces several components of the UPR target genes, including XBP1 and ATF6, which induce a UPR program for maintaining ER integrity and protein homeostasis [97], although the induction of its UPR target genes may be through NRF1 [98].

Both genes are present in species ranging from humans to yeast, and their protein products interact to form a complex composed of a beta barrel domain and an alpha helical bundle domain. General antioxidant pathways induced by NRF2 include enzymes for the reduced glutathione (GSH) production, utilization, and regeneration. As a control, plants were sprayed with a mock solution containing 0.015% (v/v) Silwet and 0.033% (v/v) ethanol. However, it was reported that NRF2 can also indirectly regulate G6PD, PGD, and TKT by downregulating the expression of miR-1 and miR-206 [85]. Reisman S.A., Yeager R.L., Yamamoto M., Klaassen C.D.

Because iron can promote the formation of damaging oxygen radicals, synthesis and destruction of iron-bound heme are carefully regulated.

These comprehensive cytoprotective proteins encoded by NRF2-target genes are essential for protection against a variety of toxic and oxidative insults and therefore many diseases that have oxidative stress as underlying pathological features, including cardiovascular disease, metabolic syndrome, neuronal degeneration, autoimmune disorders, and cancer. In addition, KEAP1 dependent but cysteine independent mechanisms were reported to stabilize NRF2 by interfering with formation of the NRF2-KEAP1 complex. NRF2 activation enhances glycolytic flux, PPP, amino acid metabolism, and glutaminolysis, resulting in an increased entry of their substrates and reducing equivalents into the TCA cycle and the mitochondrial respiratory chain. Two of RBPs, HuR and AUF1 binds to the 3-UTR of NFE2L2 mRNA and result in the elevated NRF2 activation [47].

NRF-deficient dendritic cells have impaired GSH levels, reduced phagocytic activity, augmented expression of MHC class II, and enhanced co-stimulatory receptor expression of CD86 and CD80, thereby enhancing T cells stimulatory capacity [145]. Activator protein 1 (AP-1) subunit c-Jun can dimerize with NRF2 and activate NRF2-induced transcription, while another AP-1 subunit c-Fos can suppress NRF2-induced transcription [55,56]. Consistent with this study, liver-specific constitutive NRF2 activation also reduces gluconeogenesis-related gene PCK1 and pyruvate dehydrogenase kinase (PDK1) [75].
