The Nrf2-ARE pathway: a valuable therapeutic target for the treatment of neurodegenerative diseases. (5/39)

Modulation of NF-E2 related factor 2 (Nrf2) has been shown in several neurodegenerative disorders. The overexpression of Nrf2 has become a potential therapeutic avenue for various neurodegenerative disorders such as Parkinson, Amyotrophic lateral sclerosis, and Alzheimer's disease. The expression of phase II detoxification enzymes is governed by the cis-acting regulatory element known as antioxidant response element (ARE). The transcription factor Nrf2 binds to ARE thereby transcribing multitude of antioxidant genes. Keap1, a culin 3-based E3 ligase that targets Nrf2 for degradation, sequesters Nrf2 in cytoplasm. Disruption of Keap1-Nrf2 interaction or genetic overexpression of Nrf2 can increase the endogenous antioxidant capacity of the brain thereby rendering protection against oxidative stress in neurodegenerative disorders. This review primarily focuses on recent patents that target Nrf2 overexpression as a promising therapeutic strategy for the treatment of neurodegenerative disorders.  (+info)

Nrf2 is a master regulator of the antioxidant response. The antioxidant response is important for the amelioration of oxidative stress. Oxidative stress can result in cancer, cardiovascular diseases, inflammation, neurological diseases, and renal disease. Because Nrf2 is able to induce genes important in combating oxidative stress, thereby activating the bodys own protective response, it is able to protect from a variety of [oxidative stress]-related complications , even in situations where the administration of exogenous antioxidants have failed.NFE2, NFE2L1, and NFE2L2 comprise a family of human genes encoding basic leucine zipper (bZIP) transcription factors. They share highly conserved regions that are distinct from other bZIP families, such as JUN and FOS, although remaining regions have diverged considerably from each other.

View more ,Anthocyanins have been reported to induce the expression of enzymes involved in both cellular antioxidant defenses and attenuating inflammation-associated pathogenesis. Induction of such enzymes by edible anthocyanin largely accounts for their atherosclerosis chemo-protective activities. Nuclear factor erythroid 2-related factor 2 (Nrf2) plays an essential role in the coordinated induction of those genes encoding redox-responsive and cellular defense antioxidant enzyme termed antioxidant response element (ARE). Current studies have revealed that Nrf2-ARE signaling is involved in attenuating inflammation-associated pathogenesis such as atherosclerosis. Conversely, reduction in Nrf2 signaling leads to enhanced susceptibility to oxidative stress and inflammatory tissue injuries. The activation of Nrf2-ARE might inhibit the production of pro-inflammatory mediator including cyclooxygenase-2, chemokines, cytokines, cell adhesion molecules, and induction nitric oxide synthase. This review ...
Drug resistance during chemotherapy is the major obstacle to the successful treatment of many cancers. Here, we report that inhibition of NF-E2-related factor 2 (Nrf2) may be a promising strategy to combat chemoresistance. Nrf2 is a critical transcription factor regulating a cellular protective response that defends cells against toxic insults from a broad spectrum of chemicals. Under normal conditions, the low constitutive amount of Nrf2 protein is maintained by the Kelch-like ECH-associated protein1 (Keap1)-mediated ubiquitination and proteasomal degradation system. Upon activation, this Keap1-dependent Nrf2 degradation mechanism is quickly inactivated, resulting in accumulation and activation of the antioxidant response element (ARE)-dependent cytoprotective genes. Since its discovery, Nrf2 has been viewed as a good transcription factor that protects us from many diseases. In this study, we demonstrate the dark side of Nrf2: stable overexpression of Nrf2 resulted in enhanced resistance of ...

An Italian doctor says that he came up with a cure for many types of MS. He also feels that he knows what cause these types of the disease. The doctors name is Paolo Zamboni. He says that there are pathways in the brain that get rid of extra iron that the brain does not need. In the brains of MS patients, they passages are blocked, which causes a build up of iron in the brain. The cure, he says, is a surgery to open some of the main veins in the brain that aid in moving this extra iron. his research all started when MS hit close to home, his wife was diagnosed. He began doing deep and intense research on the disease and found very old information on a the theory of iron build-up as the cause. When the iron builds up in the brain, it damages blood vessels that are vital to the body. He began taking ultrasounds on all of the patients he was treating for MS. Surprisingly these ultrasounds confirmed his theory. More than 90% of the patients have some sort of blockage in the veins that drain blood ...

We compared antioxidant responses and regulation of porphyrin metabolism in rice plants treated with oxyfluorfen (OF) or methyl viologen (MV). Plants treated with MV exhibited not only greater increases in conductivity and malondialdehyde but also a greater decline in Fv/Fm, compared to plants treated with OF. MV-treated plants had greater increases in activities of superoxide dismutase (SOD) and catalase (CAT) as well as transcript levels of SODA and CATA than OF-treated plants after 28 h of the treatments, whereas increases in ascorbate peroxidase (APX) activity and transcript levels of APXA and APXB were greater in OF-treated plants. Both OF- and MV-treated plants resulted in not only down-regulation of most genes involved in porphyrin biosynthesis but also disappearance of Mg-porphyrins during the late stage of photooxidative stress. By contrast, up-regulation of heme oxygenase 2 (HO2) is possibly part of an efficient antioxidant response to compensate photooxidative damage in both treatments. Our
Oxidative stress has been implicated in the pathogenesis of Friedreichs Ataxia (FRDA), a neurodegenerative disease caused by the decreased expression of frataxin, a mitochondrial protein responsible of iron homeostasis. Under conditions of oxidative stress, the activation of the transcription factor NF-E2-related factor (Nrf2) triggers the antioxidant cellular response by inducing antioxidant response element (ARE) driven genes. Increasing evidence supports a role for the Nrf2-ARE pathway in neurodegenerative diseases. In this study, we analyzed the expression and the distribution of Nrf2 in silenced neurons for frataxin gene. Decreased Nrf2 mRNA content and a defective activation after treatment with pro-oxidants have been evidenced in frataxin-silenced neurons by RT-PCR and confocal microscopy. The loss of Nrf2 in FRDA may greatly enhance the cellular susceptibility to oxidative stress and make FRDA neurons more vulnerable to injury. Our findings may help to focus on this promising target, especially
TY - JOUR. T1 - Relevance of anti-inflammatory and antioxidant activities of exemestane and synergism with sulforaphane for disease prevention. AU - Liu, Hua. AU - Talalay, Paul. PY - 2013/11/19. Y1 - 2013/11/19. N2 - Exemestane (6-methyleneandrosta-1,4-diene-3,17-dione) is a synthetic steroidal inhibitor of the aromatase reaction that catalyzes the terminal and rate-limiting step of the biosynthesis of estrogens. It is active clinically in preventing, delaying progression of, and treating mammary cancers, many of which are estrogen receptor-positive. A striking feature of the structure of exemestane is an extended system of conjugated Michael reaction functions, which is also characteristic of inducers of a broad network of chemoprotective genes regulated by the Keap1 (Kelch-like ECAassociated protein)/Nrf2 (nuclear factor E2-related factor 2)/ARE (antioxidant response element) signaling system. These genes are largely involved in xenobiotic metabolism and antioxidative and anti-inflammatory ...
Chronic treatment with azathioprine, a highly effective anti-inflammatory and immunosuppressive agent, profoundly increases the risk for development of unusually aggressive cutaneous squamous cell carcinoma. Its ultimate metabolite, 6-thioguanine (6-TG) nucleotide, is incorporated in DNA of skin cells, and upon exposure to UVA radiation, causes oxidative stress, followed by damage of DNA and associated proteins. The acetylenic tricyclic bis(cyano enone) TBE-31 is a strong inhibitor of inflammation and a potent inducer of the Keap1/Nrf2/ARE pathway, which orchestrates the expression of a large network of cytoprotective genes. We now report that long-term (five days per week for four weeks) topical daily applications of small (200 nmol) quantities of TBE-31 cause a robust systemic induction of the Keap1/Nrf2/ARE pathway and decreases the 6-TG incorporation in DNA of skin, blood, and liver of azathioprine-treated mice, indicating extraordinary bioavailability and efficacy. In addition, TBE-31, at ...
Excessive oxidative stress is a common pathological mechanism, which has been demonstrated to be involved in the progression of OA (16-18). Excessive oxidative stress can increase the secretion of inflammatory cytokines and alter the function of multiple signaling pathways in chondrocytes, causing cell dysfunction, extracellular matrix degradation and the programmed cell death or necrosis of chondrocytes during OA (19-21). Nrf2 is known to regulate antioxidant protein expression, which protects against the oxidative damage induced by inflammation and injury. Usually, Nrf2 resides in the cytoplasm and translocates to the nucleus during conditions of stress. Nrf2 binds to the antioxidant response elements, which are located in the promoter region, and one of the target genes is HO-1, which counteracts the oxidative damage in various tissue injuries (22-24). The expression of HO-1 has been reported to be upregulated in numerous inflammatory diseases, as a physiological response to oxidant damage in ...
Aim 1 was to elucidate the effects of diesel exhaust particulate (DEP) and ambient PM components on the generation of oxidative stress and inflammation in cellular studies performed in vitro. We demonstrated that DEP induces reactive oxygen species (ROS) production in macrophages and bronchial epithelial cells, and that these effects can be reproduced by methanol extracts made from these particles. ROS generation by pro-oxidative PM chemicals induced a hierarchical oxidative stress response in which a protective antioxidant defense (Tier 1) upgrades to pro-inflammatory (Tier 2) and cytotoxic effects (Tier 3) as the level of oxidative stress increases. An example of a Tier 1 antioxidant defense is the expression of HO-1. This gene is activated by the nuclear accumulation of Nrf2. This transcription factor drives the antioxidant response element (ARE) in the promoter of phase II enzymes, leading to increased expression of hemoxygenase-1, glutathione-S- transferase, NADPH quinone oxidoreductase, ...

There are 3 main types of disc injuries. The first disc injury consists of annular fiber tears which do not extend to the outer aspects of the disc. Thus, the inner nuclear material is prevented from completely escaping the disc. The second type of disc injury, commonly referred to as a disc herniation, consists of annular tears which run from the innermost aspects of the annulus (where the nucleus is) to the outermost aspects of the annulus. In this type of injury, the pressurized nuclear material can squeeze through the tears in the annulus and escape to the outside of the disc. When this occurs, the nuclear material may come in contact with nearby spinal nerves and even the spinal cord. In the third type of disc injury, referred to as a disc bulge, the inner nucleus loses hydration; common in those with prolonged spinal stress and the elderly. This results in bulging of the disc much like a tire bulges when it contains inadequate amounts of air. Similar to the previous injury, the nearby ...
The Keap1-Nrf2-ARE signaling pathway elicits an adaptive response for cell survival after endogenous and exogenous stresses, such as inflammation and carcinogens, respectively. Keap1 inhibits the transcriptional activation activity of Nrf2 (p45 nuclear factor erythroid-derived 2-related factor 2) in unstressed cells by facilitating its degradation. Through transcriptional analyses in Keap1- or Nrf2-disrupted mice, we identified interactions between the Keap1-Nrf2-ARE and the Notch1 signaling pathways. We found that Nrf2 recognized a functional antioxidant response element (ARE) in the promoter of Notch1. Notch1 regulates processes such as proliferation and cell fate decisions. We report a functional role for this cross talk between the two pathways and show that disruption of Nrf2 impeded liver regeneration after partial hepatectomy and was rescued by reestablishment of Notch1 signaling.. ...

Kang-fu-ling (KFL) is a polybotanical dietary supplement with antioxidant properties. This study aimed to evaluate the potential protective effects of KFL on cognitive deficit induced by high-power microwave (HPM) and the underlying mechanism for this neuroprotection. The electron spin resonance technique was employed to evaluate the free radical scavenging activity of KFL in vitro and KFL exhibited scavenging hydroxyl radical activity. KFL at doses of 0.75, 1.5 and 3 g kg-1 and vehicle were administered orally once daily for 14 days to male Wistar rats after being exposed to 30 mW cm-2 HPM for 15 minutes. KFL reversed HPM-induced memory loss and the histopathological changes in hippocampus of rats. In addition, KFL displayed a protective effect against HPM-induced oxidative stress and activated the nuclear factor-E2-related factor 2 (Nrf2) and its target genes in the hippocampus of rats. The Nrf2-antioxidant response element (ARE) signaling pathway may be involved in the neuroprotective effects ...

Compelling evidences have shown that diverse environmental insults arising during early life can either directly lead to a reduction in the number of dopaminergic neurons or cause an increased susceptibility to neurons degeneration with subsequent environmental insults or with aging alone. Oxidative stress is considered the main effect of neurotoxins exposure. In this study, we investigated the oxidative stress effect of Paraquat (PQ) on immortalized human embryonic neural progenitor cells by treating them with various concentrations of PQ. We show that PQ can decrease the activity of SOD and CAT but increase MDA and LDH level. Furthermore, the activities of Cyc and caspase-9 were found increased significantly at 10 |i|μ|/i|M of PQ treatment. The cytoplasmic Nrf2 protein expressions were upregulated at 10 |i|μ|/i|M but fell back at 100 |i|μ|/i|M. The nuclear Nrf2 protein expressions were upregulated as well as the downstream mRNA expressions of HO-1 and NQO1 in a
The potential mechanisms of action of ozone therapy are reviewed in this paper. The therapeutic efficacy of ozone therapy may be partly due the controlled and moderate oxidative stress produced by the reactions of ozone with several biological components. The line between effectiveness and toxicity of ozone may be dependent on the strength of the oxidative stress. As with exercise, it is well known that moderate exercise is good for health, whereas excessive exercise is not. Severe oxidative stress activates nuclear transcriptional factor kappa B (NFκB), resulting in an inflammatory response and tissue injury via the production of COX2, PGE2, and cytokines. However, moderate oxidative stress activates another nuclear transcriptional factor, nuclear factor-erythroid 2-related factor 2 (Nrf2). Nrf2 then induces the transcription of antioxidant response elements (ARE). Transcription of ARE results in the production of numerous antioxidant enzymes, such as SOD, GPx, glutathione-s-transferase(GSTr),

These include the beneficial fibers in cabbage, the content of glutamine (an amino acid-like substance used by intestinal cells for healing), and a high content of miraculous compounds called glucosinolates. Glucosinolates are sulfur containing molecules that have glucose attached to them. When you break open the cell walls of cabbage, an enzyme is released called myrosinase that removes the glucose from the sulfur compounds commonly called isothiocyanates. One of these isothiocyanates, sulforaphane, has an amazing capacity to turn on a part of our genes called the Antioxidant Response Element. When it does this, we start producing more antioxidant proteins, and detoxification proteins (enzymes actually) that provide us 72 hours of protection from environmentally and internally produced toxins. ...
NFE2L2 Full-Length MS Protein Standard (NP_006155), Labeled with [U- 13C6, 15N4]-L-Arginine and [U- 13C6, 15N2]-L-Lysine, was produced in human 293 cells (HEK293) with fully chemically defined cell culture medium to obtain incorporation efficiency at Creative-Proteomics. This gene encodes a transcription factor which is a member of a small family of basic leucine zipper (bZIP) proteins. The encoded transcription factor regulates genes which contain antioxidant response elements (ARE) in their promoters; many of these genes encode proteins involved in response to injury and inflammation which includes the production of free radicals. Multiple transcript variants encoding different isoforms have been found for this gene.
