Genes that are activated via the Nrf2 pathway include numerous genes involved in xenobiotic disposition (GSTs, Mrps, and quinone reductases), protection from electrophiles (GSH synthesis, superoxide dismutase), and general stress response (heme oxygenase, thioredoxin).
What is the Nrf2 gene?
The nuclear factor erythroid 2–related factor 2 (Nrf2) is an emerging regulator of cellular resistance to oxidants. Nrf2 controls the basal and induced expression of an array of antioxidant response element–dependent genes to regulate the physiological and pathophysiological outcomes of oxidant exposure.
What is the role of Nrf2?
The nuclear factor erythroid 2-related factor 2 (Nrf2) is an emerging regulator of cellular resistance to oxidants. Nrf2 controls the basal and induced expression of an array of antioxidant response element-dependent genes to regulate the physiological and pathophysiological outcomes of oxidant exposure.
Is Nrf2 a transcription factor?
Significance: Nuclear factor E2-related factor 2 (Nrf2) is a transcription factor that coordinates the basal and stress-inducible activation of a vast array of cytoprotective genes. Understanding the regulation of Nrf2 activity and downstream pathways has major implications for human health.
How do you increase Nrf2?
Plant foods are the richest source of pro-Nrf2 compounds:
- Garlic and onion (sulfur compounds)
- Broccoli, broccoli sprouts, cabbage, kale, collard greens, cauliflower, bok choy, and Brussels sprouts (sulforaphane)
- Grapes, cranberries, blueberries, mulberries, lingonberries, bilberries, jackfruit, peanuts and chocolate!
How is Nrf2 regulated?
Nrf2 activity is subjected to the regulation at various levels including protein stability, transcription, and post-transcription. Among the various regulatory pathways, the Keap1-Cul3-Rbx1 axis is the most prominent regulator of Nrf2 activity.
What ingredients are in Nrf2?
Protandim Nrf2 Synergizer contains these ingredients: Turmeric: Turmeric root is the spice that gives curry its yellow color….The Protandim® Nrf2 Synergizer™ Proprietary Blend.
| Ingredient | Measured Effect |

| Turmeric extract | 2 |
Is Nrf2 an antioxidant?
The transcription factor NRF2 is a key player in the antioxidant defense, as it can induce the transcription of antioxidant and cytoprotective genes, including GSH, through its interaction with the antioxidant response elements.
How do I activate Nrf2?
NRF2 (nuclear factor erythroid-2-related factor 2) is a transcription factor that activates over 500 genes via molecules called sirtuins. NRF2 activation can be achieved through exercise, calorie restriction (including fasting) and ingestion of natural nutrients that are NRF2 activators.
What is Nrf1 and Nrf2?
Nrf1 is a member of the vertebrate Cap’n’Collar (CNC) transcription factor family that commonly contains a unique basic-leucine zipper domain. Among CNC family members, Nrf2 is known to regulate a battery of antioxidant and xenobiotic-metabolizing enzyme genes through the antioxidant response element (ARE).
What foods trigger Nrf2?
Plant foods are the richest source of pro-Nrf2 compounds:
- Garlic and onion (sulfur compounds)
- Broccoli, broccoli sprouts, cabbage, kale, collard greens, cauliflower, bok choy, and Brussels sprouts (sulforaphane)
- Grapes, cranberries, blueberries, mulberries, lingonberries, bilberries, jackfruit, peanuts and chocolate!
Does Moringa activate Nrf2?
Moringa isothiocyanate activates Nrf2: potential role in diabetic nephropathy.
What is the function of Nrf2?
NRF2 is a cap‘n’collar basic leucine zipper transcription factor. It plays an important role in regulating antioxidant response element (ARE)-mediated gene transcription. Homozygous NRF2 knockout ( Nrf2−/−) mice are more sensitive to oxygen toxicity than their wild-type ( Nrf+/+) counterparts.
What are the Neh domains of Nrf2?
NRF2 possesses six highly conserved domains called NRF2-ECH homology (Neh) domains. The Neh1 domain is a CNC-bZIP domain that allows Nrf2 to heterodimerize with small Maf proteins ( MAFF, MAFG, MAFK ). The Neh2 domain allows for binding of NRF2 to its cytosolic repressor Keap1.
What is nf-e2/ap1 (Nrf2)?
Initially identified through cloning experiments as a factor that is able to bind the nuclear factor, erythroid-derived 2/activator protein 1 (NF-E2/AP1) repeat of the beta-globin gene, Nrf2 soon became the subject of extensive research for its role in regulating the expression of many antioxidant and detoxification enzymes ( 58, 108, 164 ).
What is the role of inrf2 in chemoprevention?
Nrf2 activation of gene expression is critical in chemoprevention and protection against cardiovascular, renal, and pulmonary disorders. INrf2 is an inhibitor of Nrf2 that serves as an adaptor for Cul3-based degradation of Nrf2. Normally, INrf2 retains Nrf2 in the cytosol.
