Disturbances in the normal redox state of cells can cause toxic effects through the production of peroxides and free radicals that damage all components of the cell, including proteins, lipids, and DNA. Further, some reactive oxidative species act as cellular messengers in redox signaling.

So Now we know what this is, HOW do we help it?! What can we do about this?! We have been using it since March. Its called Nrf2 Pathway Activator or Protandim. The difference is simply a name.

Sulforaphane Improves Autism Symptoms

So its designed to relief oxidative stress! I was on board to try it! The first few months I tried the brand my doc gave me, then I came across this brand, LifeVantage and then I learned that they have been helping many with Autism so I wanted to learn more. How it helped her nonverbal son so much he began to try and speak! And now has a few words and keeps trying to get more out daily! So we did!

We have been using this brand since this past August, and honestly seems no different…the only difference is pricing, and pill amount and type. The Nrf2 by IP another brand was a capsule and 2 caps was 1 serving. This brand is a little smaller pill and only 1 is needed daily. Also, the Protandim is slightly cheaper which helps in regards to all the other things we need to get for her, so I am sticking with Life Advantage for now.

Sabrina seems a lot less anxious happier, more relaxed and calmer in situations in which she would otherwise not be. She has shown better concentration and improved academics and behavior at school.

It seems to help relieve something. COM Neurological diseases are defined as disorders to the central and peripheral nervous systems including, but not limited to the brain, spinal chord, nerves, and muscles. Studies are underway to determine how effective NRF2 activation could be in Nrf2 Protandim Oxidative Stress and Autism.These direct acting enzymes and nutrients are great at fighting the fire of oxidative stress, but where this is a chronic condition, understanding how best to activate these antioxidants in the body is of great interest.

Most compounds and molecules in our body exist in a relatively stable state, this is why we need enzymes think of them as molecular power tools to break them down or turn them into other more useful molecules.

However, some reactions in the body lead to the formation of molecules called free radicals including reactive oxygen species and peroxidesmost notably those involved in energy generation within the cell. Put another way, the byproduct of energy metabolism are damaging free radicals. These free radicals are chemically unstable, and highly reactive. Two common examples are O 2 — sometimes called superoxide and H 2 O 2 or hydrogen peroxide.

O 2 is the normal stable form of oxygen, however when involved in some reactions in the body O 2 — is formed.

That little — sign means that an extra electron has been added. Superoxide is therefore highly reactive as it is trying to find a way to lose that extra electron, and the only way to do that is to transfer it to another molecule or compound.

This mopping up occurs constantly in the body, however, when antioxidant function in the body becomes overwhelmed by free radicals, oxidative stress can occur. It is important to understand that free radicals in themselves are not bad, their formation is part and parcel of cellular energy generation, and they serve a vital role in other functions such as bacterial killing. In the short term, oxidative stress is unlikely to be harmful, as whilst the body may be temporarily overwhelmed it will usually respond and clear any harmful compounds.

Other major areas of interest are dietary and environmental exposures. At a base level things like alcohol and tobacco or a meat rich diet can increase oxidative stress.

There are other factors however which are more difficult to avoid such as air pollution, excessive exposure to pesticides, herbicides, or heavy metals. So we know that molecules such as glutathione are great at mopping up free radicals on a one to one basis, and that enzymes such as the SOD or glutathione peroxidase GPX enzyme families can rapidly reduce oxidative stress.

But what happens in a chronic system where these defenses have been overwhelmed? Nuclear factor erythroid 2 [NF-E2]-related factor 2, known by the much easier to remember acronym Nrf2 is a transcription factor which is a major regulator of cell protective, including antioxidant, responses. Table 1 — Genes activated by NRF2.

Adapted from: Baird, L. In health, Nrf2 exists in the cytosol of a cell, or the region outside of the nucleus where it cannot interact with DNA. It is held here by another protein called Keap1, which prevents it moving into the nucleus. Keap1 contains several sensors for reactive oxygen species, along with receptor regions for other cell proteins associated with cell stress.

Both of these proteins exhibit potent antioxidant capacity and can rapidly clear oxidative stress. The important role for Nrf2 has been shown by several studies with a particular focus on animal models. Mice which have been genetically engineered to lack Nrf2 protein are considerably more sensitive to chemical carcinogens, and also chemical toxins leading to increased inflammation in the lung and brain, all major markers of oxidative stress.

All are complex in name and structure, but they share a common function in that they support increased and prolonged expression of Nrf2 gene targets. Whilst Nrf2 activation is undoubtedly beneficial in the vast majority of cases, there are some instances where it may prove harmful.

Once again using a mouse model, this time lacking Keap1, meaning that Nrf2 would be constantly activated, researchers demonstrated that severe health effects would develop.

Importantly there are no currently reported SNPs in Nrf2 which impact on its function. A lack of variation in genes like this typically points to how important they are to life, however an alternative option is that Nrf2 has not been widely investigated. The take home message in this instance is quite simple. Nrf2 is a potent modulator of antioxidant response and can rapidly target oxidative stressors. While Nrf2 responds to oxidative stress directly, certain key nutrients can improve this effect, the exact source of these nutrients varies widely but dark green and leafy vegetables think spinach, kale and broccoli, especially the seed extractor reddy vegetables and spices saffron, tumeric or paprika are a particularly rich source.

Importantly these foods are also typically rich in direct antioxidants and display numerous other health benefits, so they are a great way to improve overall health. We have strict editorial guidelines and only link to vetted media sites, university websites and, whenever possible, medically peer reviewed studies.Glyphosate use has escalated 1 at a similar rate and overlapping time frame to the increase in autism in children.

The rate of autism in Japanese children is even greater than in U.

What is Nrf2?

The herbicide Roundup has been shown to induce oxidative stress in animal studies 5and children with autism have been shown to have an increase in oxidative stress and reduced levels of an antioxidant, glutathione, 2that is made within our bodies during normal health. Use of Nrf2 promoting foods might help increase our own production of glutathione. Glyphosate may be metabolized into other chemicals within the body and it or the metabolites may inhibit enzymes important for a variety of functions throughout the body.

Baths or footsoaks provide a topical absorption route that would bypass any problems with malabsorption in the digestive system or problems with sun exposure to bioactivate other forms of sulfur into the bioactive sulfate form.

This balancing act can become disrupted as one ages, or if the body is overcome by malfunction resulting in further cellular damage. This damage is known as oxidative stress and is accompanied by free radical production.

Oxidative stress and the associated free radical damage contributes to cellular damage and aging symptoms. These antioxidant enzymes are powerful enough to neutralize up to one million free radicals per second, every second. This one to one million ratio proves to be a far more effective approach in combating cellular damage. In this way, specific molecules from Nrf2 activating foods can trigger the production of thousands of antioxidant molecules, providing far better protection against the effects of free radicals compared to standard antioxidant supplements.

Our mission is to provide an impartial review of the emerging research regarding Nrf2 activation.

Activating the Nrf2 pathway with nutrition: what you need to know

What is Nrf2? What is NRF2? The NRF2 Overview When the body is young and healthy it is able to take care of the balance between cellular damage and repair and rejuvenation. The NRF2 Overview. When the body is young and healthy it is able to take care of the balance between cellular damage and repair and rejuvenation.

Nrf2 is a powerful protein that is latent within each cell in the bodyunable to move or operate until it is released by an Nrf2 activator. Direct antioxidants Direct antioxidants such as vitamin C, Vitamin E, berries and juices have typically been used to neutralize free radicals and to prevent the damage they cause.

However there comes a tipping point where the direct antioxidants are inadequate to take care of the damage. The Right Choice. Nrf2 activators. Since the Nrf2 protein remains dormant in a cell until it is activated by a Nrf2 activator. Nutrigenomics Through the study of Nutrigenomics, it has been determined that a variety of foods are powerful activators of the Nrf2 pathway. David Perlmutter M. Other NRF2 Resources:.

Researchers, Leave A Message.Metrics details. Increasing evidence indicates that brain inflammation is involved in the pathogenesis of neuropsychiatric diseases. There is still no definitive pathogenesis or reliable biomarkers for ASD, thus significantly curtailing the development of effective therapies. Many children with ASD regress at about age 3 years, often after a specific event such as reaction to vaccination, infection, stress or trauma implying some epigenetic triggers, and may constitute a distinct phenotype.

ASD children respond disproportionally to stress and are also affected by food and skin allergies. Corticotropin-releasing hormone CRH is secreted under stress and together with neurotensin NT stimulates mast cells and microglia resulting in focal brain inflammation and neurotoxicity.

NT stimulates mast cell secretion of mtDNA that is misconstrued as an innate pathogen triggering an auto-inflammatory response. The phosphatase and tensin homolog PTEN gene mutation, associated with the higher risk of ASD, which leads to hyper-active mammalian target of rapamycin mTOR signalling that is crucial for cellular homeostasis.

CRH, NT and environmental triggers could hyperstimulate the already activated mTOR, as well as stimulate mast cell and microglia activation and proliferation. Increasing evidence indicates that brain inflammation is important in the pathogenesis of neuropsychiatric disorders [ 12 ]. Autism spectrum disorders ASD are pervasive neuro-developmental disorders characterized by varying degrees of deficiencies in social interactions, intelligence, and language, as well as the presence of stereotypic behaviors [ 3 — 6 ].

Many such children regress at about age 3 years, often after a specific event such as reaction to vaccination, infection [ 89 ], trauma [ 1011 ], toxic exposures [ 12 ] or stress [ 13 ], implying the importance of some environmental triggers [ 1415 ]. In fact, mast cells are the only immune cells that store pre-formed TNF and can release it rapidly upon stimulation [ 20 ]. Mast cells and cytokines such as IL-6 and TNF are also implicated in disruption of the blood—brain barrier BBB [ 21 — 23 ], which may be malfunctioning or leaky in ASD as evidenced by the presence of circulating auto-antibodies directed against the fetal brain proteins [ 24 — 27 ].

We had reported that the cytokine IL synergizes with inflammatory neuropeptides to stimulate mast cells and result in increased vascular permeability [ 28 ]. IL has been considered an alarmin, acting through mast cells to alert the innate immune system [ 2930 ], and has recently been linked to brain inflammation [ 31 — 33 ].

We have also reported that neurotensin NT and corticotropin-releasing hormone CRHsecreted under stress, synergistically stimulate mast cells, leading to increase vascular permeability [ 34 ] and contribute to BBB disruption [ 35 ].

We further showed that NT stimulates mast cell secretion of vascular endothelial growth factor VEGF [ 36 ], which is also vasodilatory. NT is a vasoactive peptide originally isolated from the brain [ 39 ], but also found in the gut where it has been implicated in inflammation [ 40 ], and in increased intestinal permeability in rodents [ 41 ]. NT is also increased in the skin following acute stress, stimulates skin mast cells and increases vascular permeability in rodents [ 42 ].

NT stimulates rodent peritoneal mast cells to secrete histamine and elevates histamine plasma levels through activation of specific NT receptors NTR [ 43 — 45 ]. Moreover, NT is rapidly degraded by mast cell proteases [ 3446 ] implying tight regulation of its activity.

Mast cells are hemopoietic-derived tissue immune cells responsible for allergies, but also implicated in immunity [ 47 ] and inflammation [ 18 ]. Mast cells can produce both pro- and anti-inflammatory mediators [ 48 ] and may have immuno-modulatory functions [ 4749 — 51 ].

It is, therefore, of interest that allergic-like reactions are common in ASD children [ 5253 ] implying activation of mast cells by non-allergic triggers [ 17 ]. The richest source of mast cells in the brain is the diencephalon [ 54 ] that regulates behavior, while the highest concentration of NTR is in the Broca area [ 55 ], which regulates language, known to be lost in many children with ASD. Mast cells are responsible for eliciting neutrophil infiltration that promotes inflammation [ 56 ].

Mast cell-microglial interactions are important in neuroinflammatory diseases [ 5758 ]. Microglia are the innate brain immune cells that are increasingly implicated in a number of neuropsychiatric diseases [ 59 ]. In fact, abnormal microglial growth and activation was recently reported in the brain of ASD patients [ 6061 ].

Microglia express NTR3, activation of which leads to their proliferation [ 62 ]. In fact, the glutamate receptor mGluR5 was reported to be overactive in fragile X mice [ 6667 ], a condition associated with high risk of ASD.

Diagrammatic representation of how stimulation of mast cells and microglia could lead to multiple effects that contribute brain inflammation and the pathogenesis and symptoms of autism.

MCP, monocyte chemotactic protein. There is also support for increased oxidative stress [ 68 ] and some mitochondrial mt defects at least in subgroups of patients with ASD [ 69 ]. We showed that mtDNA is significantly increased in the serum of young autistic children [ 70 ], who also had significantly increased serum level of NT [ 71 ]; this triggers mast cells to secrete mtDNA [ 38 ] that acts as innate pathogen to stimulate mast cells [ 72 ] and other immune cells, leading to auto-inflammation [ 73 ].

Moreover, mtDNA can cause neuronal degeneration and altered behavior [ 74 ]. In spite of the fact that almost gene mutations have been identified in patients with ASD [ 7778 ], they do not explain more than a few percent of ASD cases [ 6 ]. These proteins are upstream inhibitors of the mammalian target of rapamycin mTOR [ 7779 ], which leads to microglia and mast cell proliferation [ 8081 ].Have you heard of the anti-aging supplement Protandim?

Unlike other products, Protandim is said to work by helping the body increase its own natural antioxidant enzymes. Sounds good, but does Protandim work or is it a scam? These are some of the questions I will address in this review. The good news is there are clinical studies on Protandim. I will use that research in this review and help you understand it.

By the end of this review, you'll have a better idea if Protandim is right for you. Protandim might sound like a drug but it's really a dietary supplement. It's said to combat free radical damage oxidative stress by stimulating the production of the body's own natural antioxidant enzymes such as catalase, superoxide dismutase SOD and glutathione.

So, instead of taking individual antioxidant supplements like vitamins C, E, etc. The supplement website LifeVantage. Protandim is a product of a company called LifeVantage Corporation. Its stock symbol is LFVN. The company is located at S. That is good. It tells us the company has a physical location.

See the BBB file for updates and more information. These additional ingredients play no role in the effects or benefits of the product. I want to commend the LifeVantage company for sponsoring much of the research below. It's rare to find a product with so many clinical studies. Protandim is different from a lot of supplements because there really is clinical research on this product.

Below is a summary of the Protandim research with links to the studies for those who want to see them for themselves. Because scientific studies can be wordy and complicated for most people, I will summarize the study and put the research in proper context to make them easier to understand.

The study involved 38 runners who were randomly given either Protandim or a placebo. The researchers report however that in those over age 35, Protandim improved SOD twice as much as those taking the placebo. Study summary: Researchers sought to determine what effect various compounds had on extending the life of mice. Protandim was one of the compounds tested. The other compounds tested in the study were fish oil, ursodeoxycholic acid a bile acid, used to dissolve gall stones and the diabetes drug, metformin.

Different mice received the different compounds for their lifespan. Beginning at 10 months of age, mice received Protandim at a dosage of parts per million ppm in their food. This amount was chosen because it was similar to what people use when they use Protandim.The transcription factor NRF2 nuclear factor erythroid 2-related factor 2 triggers the first line of homeostatic responses against a plethora of environmental or endogenous deviations in redox metabolism, proteostasis, inflammation, etc.

Therefore, pharmacological activation of NRF2 is a promising therapeutic approach for several chronic diseases that are underlined by oxidative stress and inflammation, such as neurodegenerative, cardiovascular, and metabolic diseases.

A particular case is cancer, where NRF2 confers a survival advantage to constituted tumors, and therefore, NRF2 inhibition is desired. This review describes the electrophilic and nonelectrophilic NRF2 activators with clinical projection in various chronic diseases. We also analyze the status of NRF2 inhibitors, which at this time provide proof of concept for blocking NRF2 activity in cancer therapy. Nuclear factor erythroid 2-related factor 2 NRF2 is the product of the NFE2L2 gene and belongs to the cap n collar transcription factor family.

By sequence homology with other orthologs, the domains termed Neh have been traditionally allocated in this protein Figure 1 a. These heterodimers regulate the expression of about human genes that present a regulatory enhancer sequence termed Antioxidant Response Element ARE; 5 - TGACNNNGC-3 and participate in multiple homeostatic functions including regulation of inflammation, redox metabolism, and proteostasis [ 3 — 6 ].

From a clinical perspective, it is of utmost importance that NRF2 can be targeted pharmacologically in diseases underlined by oxidative stress and inflammation, such as neurodegenerative, vascular, and metabolic diseases as well as cancer [ 78 ]. In models of most chronic diseases, a reinforcement of homeostasis through NRF2 activators provides a beneficial therapeutic effect.

In cancer, the pharmacological regulation of NRF2 appears to be context dependent. It is generally accepted that NRF2 inhibitors not only reduce the survival and proliferative advantage of cancer cells but also sensitize tumors to chemo- and radiotherapy [ 9 ].

In this review, we describe the pharmacological activators of NRF2 that are in several stages of pharmacological development for the treatment of several chronic diseases. We also discuss the current state of NRF2 inhibitors which may be highly relevant for cancer therapeutics although at this time they are still in early phases of development.

NRF2 is ubiquitously and constitutively expressed by cells, thus ensuring their prompt protective response to oxidative, inflammatory, and metabolic stresses.

Therefore, under nonstressed conditions, low NRF2 levels provide basal expression of its target genes. KEAP1 contains 27 cysteine residues in humans, converting this protein in a redox sensor for endogenous and environmental oxidative signals as well as for electrophilic reactions [ 15 ].

Under redox-challenging conditions, the cellular redox buffers comprising glutathione GSHthioredoxin, etc. However, ROS oxidize thiols and induce glutathionylation and alkylation of macromolecules, therefore having the capacity to modify KEAP1 cysteines [ 16 ].

nrf2 activator autism

From a pharmacological perspective, electrophile reaction with some cysteines of KEAP1 leads to the formation of adducts that prevent the ubiquitination NRF2, resulting in its stabilization, nuclear translocation, and transcriptional induction of NRF2-target genes [ 78 ]. NRF2 can be regulated at the transcriptional level.

These compounds can be classified as electrophiles, protein-protein interaction PPI inhibitors, and multitarget drugs Figure 2. Most pharmacological NRF2 activators are electrophilic molecules that covalently modify cysteine residues present in the thiol-rich KEAP1 protein by oxidation or alkylation [ 32 — 34 ]. Many cysteines of KEAP1 are modified by different electrophiles [ 35 — 37 ]. Cysteines Cys, Cys, and Cys [ 3839 ] appear to be the most susceptible to electrophile reaction [ 4041 ].

Other sensitive cysteines are Cys, Cys, and Cys Selected electrophilic activators of NRF2 that are in various stages of clinical development are presented in Table 1. Synthetic triterpenoids have been derived from the natural compound oleanolic acid to provide them with strong Michael acceptor reactivity.

This is achieved mainly through the addition of enone and ciano groups to the A ring and another enone group to the C ring [ 4647 ]. A new phase II clinical trial has recently started recruiting patients with rare chronic kidney diseases to better define the safety and efficacy profiles of CDDO-Me.

Recently, a preclinical study evaluated RTA for diabetic wound recovery and pointed NRF2 upregulation as responsible for the observed improvement in regenerative capacity [ 51 ].
