Abstract
Parkinson's disease (PD) is the second most common neurodegenerative disorder. The primary pathological features of PD include the presence of α-synuclein aggregates and Lewy bodies, mitochondrial dysfunction, oxidative stress, and neuroinflammation. Recently, omega-3 fatty acids (ω-3 PUFAs) have been under investigation as a preventive and/or therapeutic strategy for PD, primarily owing to their antioxidant and anti-inflammatory properties. Therefore, the objective of this study was to conduct a systematic review of the literature, focusing on studies that assessed the effects of ω-3 PUFAs in rodent models mimicking human PD. The search was performed using the terms "Parkinson's disease," "fish oil," "omega 3," "docosahexaenoic acid," and "eicosapentaenoic acid" across databases PUBMED, Web of Science, Science Direct, Scielo, and Google Scholar. Following analysis based on predefined inclusion and exclusion criteria, 39 studies were included. Considering behavioral parameters, pathological markers of the disease, quantification of ω-3 PUFAs in the brain, as well as anti-inflammatory, antioxidant, and anti-apoptotic effects, it can be observed that ω-3 PUFAs exhibit a potential neuroprotective effect in PD. In summary, this systematic review presents significant scientific evidence regarding the effects and mechanisms underlying the neuroprotective properties of ω-3 PUFAs, offering valuable insights for the development of future clinical investigations.

Abstract
Parkinson's Disease (PD) is characterised by degeneration of the neurons of the nigrostriatal dopaminergic pathway of the brain. The pharmacological cornerstone of PD management is mainly the use of dopamine precursors, dopamine receptor agonists, and agents that inhibit the biochemical degradation of dopamine. While these drugs initially provide relief to the symptoms and improve the quality of life of the patients, progression of the underlying pathological processes, such as oxidative stress and neuroinflammation (which have been strongly associated with PD and other neurodegenerative disorders), eventually reduce their benefits, making further benefits achievable, only at high doses due to which the magnitude and frequency of side-effects are amplified. Also, while it is becoming obvious that mainstream pharmacological agents may not always provide the much-needed answer, the question remains what succour can nature provide through dietary supplements, nutraceuticals and herbal remedies? This narrative review examines current literature for evidence of the possible roles (if any) of nutraceuticals, dietary supplements and herbal remedies in the prevention or management of PD by examining how these compounds could modulate key factors and pathways that are crucial to the pathogenesis and/or progression of PD. The likely limitations of this approach and its possible future roles in PD prevention and management are also considered.

Nutrients 2021; 13:nu13041050.

Abstract
The high polyphenols content of cranberry accounts for its strong antioxidant activity underlying the beneficial health effects of this fruit. Rotenone (ROT) is a specific inhibitor of mitochondrial complex I in the brain which leads to the generation of oxidative stress. To date, there are few data indicating that toxicity of ROT is not limited to the brain but can also affect other tissues. We aimed to examine whether ROT-induced oxidative stress could be counteracted by cranberry juice not only in the brain but also in the liver and kidney. Wistar rats were given the combined treatment with ROT and cranberry juice (CJ) for 35 days. Parameters of antioxidant status were determined in the organs. ROT enhanced lipid peroxidation solely in the brain. The increase in the DNA damage was noticed in all organs examined and in leukocytes. The beneficial effect of CJ on these parameters appeared only in the brain. Additionally, CJ decreased the activity of serum hepatic enzymes. The effect of CJ on antioxidant enzymes was not consistent, however, in some organs, CJ reversed changes evoked by ROT. Summing up, ROT can cause oxidative damage not only in the brain but also in other organs. CJ demonstrated a protective effect against ROT-induced toxicity.

Abstract
Endoplasmic reticulum (ER) stress was reported to play a major role in non-alcoholic fatty liver disease (NAFLD) induction and progression. Here, we study the effect of Zingiber officinale and omega-3 fatty acids on ER stress for treating NAFLD. Male Wistar rats were fed on a normal diet (control group) or high-fat diet (HFD) for 8 weeks. The HFD rats were later treated with vehicle, omega-3 or with Z. officinale extract. HFD group demonstrated significantly more body weight gain and higher plasma lipid profile, glucose, and hepatic enzymes. The expressions of lipogenic ChREBP and ER stress genes CHOP, XBP1, and GRP78 were increased. This was accompanied by intrahepatic fat accumulation visualized by hepatic morphology and H&E-stained sections. Treatment with Z. officinale and omega-3 fatty acids reverted these changes into a normal healthy state. From these results, we prove that both therapeutic approaches can be potential drugs for treating NAFLD besides other ER stress-associated diseases. PRACTICAL APPLICATIONS: The effect of Zingiber officinale extract and omega-3 fatty acid on ER stress associated with NAFLD was investigated. The results revealed that Z. officinale extract and omega-3 fatty acids significantly inhibited ER stress and intrahepatic fat accumulation with the upper hand for Z. officinale extract. Both can be used as future promising therapies for the treatment of NAFLD patients and also treating different diseases that involve ER stress as a pathological modulator like diabetes mellitus, Alzheimer's disease, Parkinson's disease, and cancer.

Abstract
Cisplatin (CP) is a major antineoplastic drug for the treatment of solid tumors, however, its clinical utility is limited by nephrotoxicity. Also, radiotherapy is an important treatment modality for many malignancies. The present studies were performed to test whether fish oil (FO) and/or selenium nanoparticles (SeNPs) administration have an ameliorative effect on CP and γ-irradiation induced nephrotoxicity. FO and/or SeNPs were administered to male albino rats daily for 12 days before being intraperitoneally injected with a single dose of CP (10 mg/kg body weight) and whole body exposed to a single dose of γ-radiation (0.7 Gy). Biochemical analysis and histopathological examination were performed. Pretreatment with FO and/or SeNPs before the administration of CP and exposure to γ-radiation significantly reduced CP- and γ-radiation-induced high levels of serum urea and creatinine and renal tumor necrosis factor-α, caspase-3 and cyclooxygenase-2, also they significantly prevented renal total antioxidant capacity levels decrease and ameliorated the levels of most studied trace elements. The histopathological results supported the biochemical findings of this study. The administration of FO and/or SeNPs might be useful for preventing nephrotoxicity which can be caused by CP and radiotherapy during the treatment of various malignancies.

Abstract
BACKGROUND Mitochondrial dysfunction is involved in neurodegenerative diseases, such as Huntington's disease (HD). 3-Nitropropionic acid (3-NP) is a mitochondrial toxin that specifically inhibits complex II of the electron transport chain (ETC) and is used to generate an experimental model of HD. OBJECTIVE To study the effect of fish liver oil (FO) over the mitochondrial dysfunction induced via partial ETC inhibition by 3-NP. METHODS This study was performed in rats and consisted of two phases: (i) administration of increasing doses of 3-NP and (ii) administration of FO for 14 days before to 3-NP. The rats' exploratory activity; complex I, II, III, and IV activities; and rearing behavior were observed. Additionally, the number of TUNEL-positive cells and various mitochondrial parameters, including oxygen consumption, transmembrane potential, adenosine triphosphate synthesis, and ETC activity, were measured. RESULTS We observed that FO exerted a protective effect against the 3-NP-induced toxicity, although complex II inhibition still occurred. Instead, this effect was related to strengthened mitochondrial complex III and IV activities. DISCUSSION Our results show that FO exerts a beneficial prophylactic effect against mitochondrial damage. Elucidating the mechanisms linking the effects of FO with its prevention of neurodegeneration could be the key to developing recommendations for FO consumption in neurological pathologies.

Abstract
In this study, comprehensive metabolic profiles of mulberry fruits (Morus alba Linnaeus) at various maturation stages were determined using GC-MS and HPLC. In total, 48 compounds, including 3 alcohols, 16 amino acids, 7 organic acids, 2 sugars, 4 phenolics, 2 terpenes, 3 vitamins, 9 fatty acids, and 2 cyanidins were identified in the mulberry samples. Levels of chlorogenic acid, cryptochlorogenic acid, neochlorogenic acid, ascorbic acid, and δ-tocopherol, and total fatty acid content were significantly higher in the semi-matured mulberry fruits. Furthermore, levels of glycerol, citrate, fructose, glucose, 3-O-glucoside, and cyanidin-3-O-rutinoside were significantly higher at the fully matured stage than at the other stages. Twelve biosynthetic pathways were suggested as major pathways involved in mulberry fruit maturation. The information obtained in this study will provide a basis for future investigations toward quality control or metabolic engineering for development of mulberry fruits possessing commercially valuable characteristics.

Abstract
Autophagy is necessary for neuronal homeostasis and its dysfunction has been implicated in Parkinson's disease (PD) as it can exacerbate endoplasmic reticulum (ER) stress and ER stress-induced apoptosis. Quercetin is a flavonoid known for its neuroprotective and antioxidant effects. The present study investigated the protective, autophagy-modulating effects of quercetin in the rotenone rat model of PD. Rotenone was intraperitoneally injected at dose of 2 ml/kg/day for 4 weeks. Simultaneous intraperitoneal injection of quercetin was given at a dose of 50 mg/kg/day also for 4 weeks. Neurobehavioral changes were studied. Oxidative/antioxidant status, C/EBP homologous protein (CHOP), Beclin-1, and dopamine levels were assessed. DNA fragmentation and histopathological changes were evaluated. This research work revealed that quercetin significantly attenuated rotenone-induced behavioral impairment, augmented autophagy, ameliorated ER stress- induced apoptosis with attenuated oxidative stress. From the current study, quercetin can act as an autophagy enhancer in PD rat model and modulates the microenvironment that leads to neuronal death.

Abstract
Physical exercise offers a highly effective health-endowering activity as has been evidence using rodent models of Parkinson's disease (PD). It is a particularly useful intervention in individuals employed in sedentary occupations or afflicted by a neurodegenerative disorder, such as PD. The several links between exercise and quality-of-life, disorder progression and staging, risk factors and symptoms-biomarkers in PD all endower a promise for improved prognosis. Nutrition provides a strong determinant for disorder vulnerability and prognosis with fish oils and vegetables with a mediterranean diet offering both protection and resistance. Three factors determining the effects of exercise on disorder severity of patients may be presented: (i) Exercise effects upon motor impairment, gait, posture and balance, (ii) Exercise reduction of oxidative stress, stimulation of mitochondrial biogenesis and up-regulation of autophagy, and (iii) Exercise stimulation of dopamine (DA) neurochemistry and trophic factors. Running-wheel performance, as measured by distance run by individual mice from different treatment groups, was related to DA-integrity, indexed by striatal DA levels. Finally, both nutrition and exercise may facilitate positive epigenetic outcomes, such as lowering the dosage of L-Dopa required for a therapeutic effect.

Combined oral supplementation of fish oil and quercetin enhances neuroprotection in a chronic rotenone rat model: relevance to Parkinson's disease. Neurochem Res 2015; 40:894-905.

Abstract
While the neuromodulatory efficacy of n-3 polyunsaturated fatty acids present in fish and fish oil (FO) are well known, some evidence in animal models suggests that chronic consumption of FO supplements may predispose the brain to lipid peroxidation. In view of this, recent approaches envisage the use of dietary antioxidants as adjuncts with FO to obtain a better clinical outcome in neurological disorders. In furtherance of our previous work, in the present study, we examined whether enrichment of FO with quercetin (Q) would enhance the neuroprotective outcome employing a chronic rotenone (ROT) model of neurotoxicity in rats. Growing male rats supplemented either with FO (2 mL/kg bw) or Q (25 mg/kg bw) or FO + Q for 28 days were administered with ROT (0.5 mg/kg bw, 21 days). Monitoring the behavioral phenotype by a battery of tests, terminally, oxidative response in brain regions, mitochondrial dysfunctions and striatal dopamine levels were determined. While both FO and Q offered varying degree of protection, the FO + Q combination offered a higher degree of protection. FO + Q combination significantly attenuated behavioral impairments, restored the ROT-induced oxidative markers, depleted dopamine levels in striatum and reduced mitochondrial dysfunction. These salient findings besides corroborating with our previous data suggest that enrichment of FO with Q indeed offers a higher degree of neuroprotection under chronic exposure to a model neurotoxin such as ROT. Hence, we propose that a combination of FO with known antioxidants such as quercetin is more likely to provide a superior therapeutic advantage in the prevention/treatment of oxidative stress-mediated neurodegenerative conditions such as Parkinson's disease.

Abstract
The beneficial effects of fish oil (FO) supplements on the central nervous system have been adequately demonstrated. However, FO supplementation at higher doses for longer duration is likely to cause oxidative stress in vivo. To overcome this, attempts have been made to enrich FO with known antioxidants/phytochemicals. In the present study, we examined the hypothesis that a combination of FO with ferulic acid (FA), a naturally occurring phenolic compound, is likely to provide higher degree of neuroprotection. This was examined by employing 3-nitropropionic acid (NPA), a well-known neurotoxin used to mimic behavioural and neurochemical features of Huntington’s disease. Growing male rats administered with NPA (25 mg/kg of body weight (bw) for 4 days) were provided with either FO (2 mL/kg bw), FA (50 mg/kg bw) or FO+FA for 2 weeks. Interestingly, FO+FA not only offered significant protection against NPA-induced behavioural impairments, but also markedly attenuated oxidative stress in brain regions (striatum/cerebellum) as evidenced by the reduction in reactive species, malondialdehyde, hydroperoxides and nitric oxide (NO) levels. Further, FO+FA combination restored the activities of various antioxidant enzymes and the levels of cytosolic calcium. In striatum, activity levels of acetylcholinesterase enzyme and dopamine levels were markedly restored among FO+FA rats. Interestingly, NPA-induced mitochondrial dysfunctions were also attenuated among FO+FA rats. Collectively, our findings suggest the advantage of co-treatment of FO with known antioxidants to achieve a higher therapeutic benefit in the treatment of oxidative stress-mediated neurodegenerative conditions.

Abstract
The reactive oxygen species produced continuously during oxidative metabolism are generated at very high rates in the brain. Therefore, defending against oxidative stress is an essential task within the brain. An important cellular system against oxidative stress is the thioredoxin system (TS). TS is composed of thioredoxin, thioredoxin reductase, and NADPH. This review focuses on the evidence gathered in recent investigations into the central nervous system, specifically the different brain regions in which the TS is expressed. Furthermore, we address the conditions that modulate the thioredoxin system in both, animal models and the postmortem brains of human patients associated with the most common neurodegenerative disorders, in which the thioredoxin system could play an important part.

Denny Joseph KM, Muralidhara. Enhanced neuroprotective effect of fish oil in combination with quercetin against 3-nitropropionic acid induced oxidative stress in rat brain. Prog Neuropsychopharmacol Biol Psychiatry 2013; 40:83-92. [PMID: 22960609 DOI: 10.1016/j.pnpbp.2012.08.018] [Citation(s) in RCA: 46] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2012] [Revised: 08/14/2012] [Accepted: 08/27/2012] [Indexed: 12/15/2022]
Abstract
While the beneficial effects of fish oil (FO) supplements on the central nervous system function are well established, few findings have led to the hypothesis that long term n-3 polyunsaturated fatty acid (n-3 PUFA) supplements at higher doses render the membranes more susceptible to lipid peroxidation. Hence recent studies suggest the use of dietary antioxidants as adjuncts with n-3 fatty acids to effectively improve the clinical outcome in neurological disorders. In the present investigation, we examined the hypothesis, if enrichment of FO with quercetin (a natural flavonoid) can provide a higher degree of neuroprotection and tested the same in a 3-nitropropionic acid (NPA) rat model. Growing male rats administered with NPA (25 mg/kg bw/d, i.p. 4 days) were provided either with FO (2 mL/kg bw), or Q (25mg/kg bw) or FO+Q for 14 days. NPA elicited marked oxidative stress in brain (striatum and cerebellum) as evidenced by significantly enhanced ROS, malondialdehyde, protein carbonyls and nitric oxide levels. Although varying degree of protection was evident among FO or Q groups, complete normalization of oxidative markers ensued only among FO+Q rats. Further, FO+Q combination completely normalized the elevated acetylcholinesterase activity and protected against NPA-induced mitochondrial dysfunctions. NPA induced depletion of dopamine levels was restored among all groups. Interestingly, NPA induced motor deficits were significantly improved among FO+Q rats. However, further studies are necessary to understand the mechanism/s by which FO enrichment with Q provides higher degree of protection. Nevertheless, our findings clearly suggest that the use of natural phytochemicals with moderate doses of FO may provide better neuroprotection and higher therapeutic advantage in the prevention or treatment of neurodegenerative diseases like Huntington's disease.
