Abstract
BACKGROUND Ferulago setifolia K. Koch (Apiaceae) has been the subject of this study, aiming to comprehensively determine its phenolic fingerprint and evaluate its various biological activities. The liquid chromatography-tandem mass spectrometry analysis of the 70% methanol extract of F. setifolia (FS) revealed the presence of 23 phytochemicals, among which chlorogenic acid, quinic acid, kaempferol-3-O-glucoside, and quercetin-3-O-glucoside were identified as the major phenolics in the extract. RESULTS The biological screening included examinations of antioxidant, antibacterial, antiproliferative, and cytotoxic activities. The FS extract displayed moderate 2,2-diphenyl-1-picrylhydrazyl radical scavenging and ferric-reducing capacity, indicating moderate antioxidant activity. Furthermore, FS exhibited significant antiproliferative effects on cancer cells while showing low cytotoxicity on normal cells. The antibacterial activity findings revealed that FS demonstrated potent activity against Pseudomonas aeruginosa, Bacillus cereus, Staphylococcus aureus, and Escherichia coli. CONCLUSION The findings of this study suggest that the methanolic extract of FS holds promise as a potential source of biologically active compounds. It can be utilized for the development of pharmaceutical formulations, thanks to its significant antiproliferative and antibacterial activities. Additionally, FS can serve as a valuable source of chlorogenic acid for industrial applications. © 2023 Society of Chemical Industry.

Abstract
The goal of the current study was to examine the therapeutic potential of green coffee bean extract (GCBE) in the treatment of diabetic hepatic damage induced by high-fat diet (HFD) and streptozotocin (STZ) administration. The novelty of this study lies in constructing a newly stabilized in vivo obese diabetic animal model in rats using HFD/STZ for investigating the dose-dependent effect of two commonly used doses of GCBE in hepatoprotection against oxidative stress-induced hepatic damage by measuring many parameters that have not been carried out previously in other studies. GCBE that was used in this study was a hot water extract of green coffee beans with a concentration of 0.1 g ml−1. Male albino rats were given a single dose of STZ (35 mg kg−1), and HFD to induce diabetes mellitus (DM). For 28 days, two separate doses of GCBE 50 mg kg−1 and 100 mg kg−1 were administered orally to diabetic animals. Leptin, liver enzymes, oxidative stress parameters, inflammatory parameters, fasting plasma glucose (FPG), fasting plasma insulin (FPI), and lipid profile levels were examined. Real-time PCR and ELISA were used to quantitatively detect the mRNAs of the genes involved in the insulin signaling pathway, the genes involved in glucose metabolism, and the amounts of proteins. The levels of FPG, lipid profile, liver enzymes, inflammatory markers, and leptin in the HFD/STZ diabetic group revealed a considerable spike, while they considerably decreased after GCBE treatment in a dose-dependent manner. After GCBE treatment, the diabetic group showed a significant rise in the antioxidant markers glutathione, superoxide dismutase, and catalase, as well as a decrease in malondialdehyde and nitric oxide levels. The liver changes caused by HFD/STZ were entirely reversed by GCBE, and most intriguingly, in a dose-dependent manner. We concluded that GCBE can repair the hepatic oxidative damage caused by HFD and STZ by reversing all the previously measured parameters and improving the insulin signaling pathways. GCBE demonstrated strong antifree radical activity and significantly protected cells from oxidative damage caused by HFD/STZ.

Abstract
In the current study, the prooxidant activities of (-)-epigallocatechin-3-gallate (EGCG) and chlorogenic acid (CGA) were systematically compared both in multiple in vitro models and in mice. At equimolar concentrations in vitro and in vivo, EGCG displayed powerful prooxidant effects though CGA exhibited none. In vitro, though CGA and EGCG synergistically produced hydrogen peroxide, CGA was able to scavenge hydroxyl radicals generated by EGCG/copper. Consistent with the selective modulation of reactive oxygen species produced from EGCG, CGA lowered hepatotoxicity but did not perturb hepatic AMPK activation nor the increase of hepatic Nrf2-associated proteins induced by high-dose EGCG. CGA, along with low-dose EGCG, synergistically activated hepatic AMPK and increased hepatic Nrf2-associated proteins without causing toxicity in mice. This proof-of-principle study suggests that polyphenols with potent prooxidant activities (e.g., EGCG) together with antioxidant polyphenols with noticeably low prooxidant activities (e.g., CGA) may yield health benefits with a low risk of side effects.

Mild pentachlorophenol-mediated uncoupling of mitochondria depletes ATP but does not cause an oxidized redox state or dopaminergic neurodegeneration in Caenorhabditis elegans. Curr Res Toxicol 2022; 3:100084. [PMID: 35957653 PMCID: PMC9361317 DOI: 10.1016/j.crtox.2022.100084] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 07/22/2022] [Accepted: 07/28/2022] [Indexed: 11/25/2022] Open
Abstract
Aims Mitochondrial dysfunction is implicated in several diseases, including neurological disorders such as Parkinson's disease. However, there is uncertainty about which of the many mechanisms by which mitochondrial function can be disrupted may lead to neurodegeneration. Pentachlorophenol (PCP) is an organic pollutant reported to cause mitochondrial dysfunction including oxidative stress and mitochondrial uncoupling. We investigated the effects of PCP exposure in Caenorhabditis elegans, including effects on mitochondria and dopaminergic neurons. We hypothesized that mild mitochondrial uncoupling by PCP would impair bioenergetics while decreasing oxidative stress, and therefore would not cause dopaminergic neurodegeneration. Results A 48-hour developmental exposure to PCP causing mild growth delay (∼10 % decrease in growth during 48 h, covering all larval stages) reduced whole-organism ATP content > 50 %, and spare respiratory capacity ∼ 30 %. Proton leak was also markedly increased. These findings suggest a main toxic mechanism of mitochondrial uncoupling rather than oxidative stress, which was further supported by a concomitant shift toward a more reduced cellular redox state measured at the whole organism level. However, exposure to PCP did not cause dopaminergic neurodegeneration, nor did it sensitize animals to a neurotoxic challenge with 6-hydroxydopamine. Whole-organism uptake and PCP metabolism measurements revealed low overall uptake of PCP in our experimental conditions (50 μM PCP in the liquid exposure medium resulted in organismal concentrations of < 0.25 μM), and no measurable production of the oxidative metabolites tetra-1,4-benzoquinone and tetrachloro-p-hydroquinone. Innovation This study provides new insights into the mechanistic interplay between mitochondrial uncoupling, oxidative stress, and neurodegeneration in C. elegans. These findings support the premise of mild uncoupling-mediated neuroprotection, but are inconsistent with proposed broad "mitochondrial dysfunction"-mediated neurodegeneration models, and highlight the utility of the C. elegans model for studying mitochondrial and neurotoxicity. Conclusions Developmental exposure to pentachlorophenol causes gross toxicological effects (growth delay and arrest) at high levels. At a lower level of exposure, still causing mild growth delay, we observed mitochondrial dysfunction including uncoupling and decreased ATP levels. However, this was associated with a more-reduced cellular redox tone and did not exacerbate dopaminergic neurotoxicity of 6-hydroxydopamine, instead trending toward protection. These findings may be informative of efforts to define nuanced mitochondrial dysfunction-related adverse outcome pathways that will differ depending on the form of initial mitochondrial toxicity.

Abstract
Chlorogenic acid (CGA) is a naturally occurring non-flavonoid polyphenol found in green coffee beans, teas, certain fruits, and vegetables, that exerts antiviral, antitumor, antibacterial, and antioxidant effects. Several in vivo and in vitro studies have demonstrated that CGA can protect against toxicities induced by chemicals of different classes such as fungal/bacterial toxins, pharmaceuticals, metals, pesticides, etc., by preservation of cell survival via reducing overproduction of nitric oxide and reactive oxygen species and suppressed pro-apoptotic signaling. CGA antioxidant effects mediated through the Nrf2-heme oxygenase-1 signaling pathway were shown to enhance the levels of antioxidant enzymes such as superoxide dismutase, catalase, glutathione-S-transferases, glutathione peroxidase, and glutathione reductase as well as glutathione content. Also, CGA could suppress inflammation via inhibition of toll-like receptor 4 and MyD88, and the phosphorylation of inhibitor of kappa B and p65 subunit of NF-κB, resulting in diminished levels of downstream inflammatory factors including interleukin (IL)-1 β, IL-6, tumor necrosis factor-α, macrophage inflammatory protein 2, cyclooxygenase-2, and prostaglandin E2. Moreover, CGA inhibited apoptosis by reducing Bax, cytochrome C, and caspase 3 and 9 expression while increasing Bcl-2 levels. The present review discusses several mechanisms through which CGA may exert its protective role against such agents. Chemical and natural toxic agents affect human health. Phenolic antioxidant compounds can suppress free radical production and combat these toxins. Chlorogenic acid is a plant polyphenol present in the human diet and exerts strong antioxidant properties that can effectively help in the treatment of various toxicities.

Abstract
Ferroptosis, an iron-dependent form of programmed cell death, is characterized by iron overload, increased reactive oxygen species (ROS) generation, and depletion of glutathione (GSH) and lipid peroxidation. Lipophilic antioxidants and iron chelators can prevent ferroptosis. GSH-dependent glutathione peroxidase 4 (GPX4) prevents lipid ROS accumulation. Ferroptosis is thought to be initiated through GPX4 inactivation. Moreover, mitochondrial iron overload derived from the degradation of ferritin is involved in increasing ROS generation. Ferroptosis has been suggested to explain the mechanism of action of organ toxicity induced by several drugs and chemicals. Inhibition of ferroptosis may provide novel therapeutic opportunities for treatment and even prevention of such organ toxicities.

Abstract
BACKGROUND AND AIMS The normal functioning of Kelch-like ECH-associated protein-1 (Keap1)/nuclear factor erythroid 2-related factor 2 (Nrf2) complex is necessary for the cellular protection against oxidative stress. We investigated the effect of chlorogenic acid (CGA), quercetin (Qt), coenzyme Q10 (Q10) and silymarin on the expression of Keap1/Nrf2 complex and its downstream target; heme oxygenase-1 (HO-1) as well as inflammation and apoptosis in an acute liver toxicity model induced by thioacetamide (TAA). MAIN METHODS Wistar rats were divided into 13 groups: Control, silymarin, CGA, Qt, Q10, TAA (single dose 50 mg/kg, i.p.), TAA + silymarin (400 mg/kg, p.o.), TAA + CGA (100 & 200 mg/kg, p.o.), TAA + Qt (200 &300 mg/kg, p.o.) and TAA+ Q10 (30&50 mg/kg, p.o.) and treated for 8 days. KEY FINDINGS The results showed improved liver functions and hepatic tissue integrity in all tested doses of TAA + silymarin, TAA + CGA, TAA + Qt and TAA + Q10 groups compared to the TAA group. Furthermore, these groups showed significantly lower ROS, malondialdehyde and nitric oxide levels but higher glutathione content and superoxide dismutase activity compared to the TAA group, p < 0.05. In these groups, Keap1 expression was significantly decreased while Nrf2 expression and HO-1 activity were increased. In addition, the number of apoptotic cells and the expression level of TNF-α in the liver tissues were significantly decreased compared to the TAA group. SIGNIFICANCE CGA, Qt, Q10 and silymarin protect against TAA-induced acute liver toxicity via antioxidant, anti-inflammatory, anti-apoptotic activities and regulating Keap1-Nrf2/HO-1 expression.

Abstract
This study reports a ≅12.5 kDa protein tetrachloro-1,4-benzoquinone reductase (CpsD) from Bacillus cereus strain AOA-CPS1 (BcAOA). CpsD is purified to homogeneity with a total yield of 35% and specific activity of 160 U·mg-1 of protein. CpsD showed optimal activity at pH 7.5 and 40 °C. The enzyme was found to be functionally stable between pH 7.0-7.5 and temperature between 30 °C and 35 °C. CpsD activity was enhanced by Fe2+ and inhibited by sodium azide and SDS. CpsD followed Michaelis-Menten kinetic exhibiting an apparent vmax, Km, kcat and kcat/Km values of 0.071 μmol·s-1, 94 μmol, 0.029 s-1 and 3.13 × 10-4 s-1·μmol-1, respectively, for substrate tetrachloro-1,4-benzoquinone. The bioinformatics analysis indicated that CpsD belongs to the PCD/DCoH superfamily, with specific conserved protein domains of pterin-4α-carbinolamine dehydratase (PCD). This study proposed that CpsD catalysed the reduction of tetrachloro-1,4-benzoquinone to tetrachloro-p-hydroquinone and released the products found in phenylalanine hydroxylation system (PheOHS) via a Ping-Pong or atypical ternary mechanism; and regulate expression of phenylalanine 4-monooxygenase by blocking reverse flux in BcAOA PheOHS using a probable Yin-Yang mechanism. The study also concluded that CpsD may play a catalytic and regulatory role in BcAOA PheOHS and pentachlorophenol degradation pathway.

Abstract
This study investigates the effect of polydatin on the neurological function of cerebral hemorrhage rats and on the Nrf2 pathway of the endogenous antioxidant system in tissues around cerebral hematoma. Further, the study also aims to provide solid insights for clinical diagnosis and treatment. A total of 54 SPF grade male Wistar rats were divided into three groups: the sham group, model group, and polydatin group. Various parameters such as neurological deficit score, brain water content, pathological morphology, oxidative stress index content, Nrf2, NQO1, HO-1 mRNA expression, and the expression of HO-1, Nrf2, and kelch-like epichlorohydrin-1 (Keap1) protein were observed. Compared with the sham group, the mNSS score and brain water content of rats in the model group increased significantly after dosing (P < 0.05). When compared with the model group, the mNSS score and brain water content of rats in the polydatin group decreased significantly after dosing (P < 0.05). Compared with the other group, the serum NSE content of rats in the polydatin group decreased (P < 0.05). An increase was observed in the contents of NO, SOD, MDA, GSSG, and GSH in the brain tissue of rats in the model group when compared with the sham group. Compared with the model group, the contents of NO and MDA in the brain tissue of rats in the polydatin group decreased, while the contents of SOD, GSSG, and GSH increased (P < 0.05). The relative expressions of Nrf2, NQO1, and HO-1mRNA in the brain tissue of rats in the polydatin group was relatively high compared with both groups (P < 0.05). Polydatin can improve the neurological function of ICH rats and reduce the oxidative stress response by regulating the Nrf2-ARE pathway and downstream gene expression. This study preliminarily discussed the relevant mechanism of polydatin in the treatment of ICH rats, thus providing a theoretical reference to ICH treatment.

Abstract
OBJECTIVES The current study evaluated the effects of green coffee extract (GCE) on serum lipid profile and adiponectin levels in patients with nonalcoholic fatty liver disease (NAFLD). DESIGN This randomized, double-blind, placebo-controlled clinical trial was conducted on NAFLD patients aged 20-60 years and body mass index (BMI) of 25-35 kg/m2. SETTING Patients were recruited from the Bahman poly-clinic (Neyshabur, Iran) between January and June 2016. INTERVENTIONS The study subjects were randomly assigned to receive a daily dose of 400 mg GCE (n = 24) or placebo (n = 24) for eight weeks. MAIN OUTCOME MEASURES Serum liver enzyme levels, lipid profile, adiponectin concentrations, and hepatic steatosis grade were measured for all patients at baseline and the end of the trial. RESULTS GCE supplementation significantly reduced BMI [mean difference (MD): -0.57 and 95 % confidence interval (CI): -0.84 to -0.29, P < 0.001] and increased serum high-density lipoprotein cholesterol (MD: 7.06, 95 % CI: 0.25-13.87, P < 0.05) compared to the control group. Serum total cholesterol decreased significantly within the GCE group (MD: -13.33, 95 % CI: -26.04 to -0.61, P < 0.05). Triglyceride levels reduced significantly in GCE group compared to the placebo group (MD: -37.91; 95 % CI: -72.03 to -3.80; P = 0.03). However, this reduction was not significant when was further adjusted for mean changes in BMI and daily energy intake (MD: -23.43; 95 % CI: -70.92 to 24.06; P = 0.32). Hepatic steatosis grade, liver enzymes, and adiponectin levels did not show significant differences between the two groups after the intervention. CONCLUSIONS GCE supplementation improved serum lipid profile and BMI in individuals with NAFLD. GCE may be useful in controlling NAFLD risk factors.

Abstract
Lead (Pb), a heavy metal which is widely recognized as an environmental toxicant, is transported from the earth's crust into the human body to a significant extent. To control and reduce the hazard of Pb burdens in the human body, chlorogenic acid (CGA) has been used to antagonize Pb-induced cognitive impairments, and hepatic and renal toxicity in the present study. Seven-week-old male Kunming mice were treated with PbCl2 (1.34 g L-1 in drinking water) and/or CGA (30 mg per kg mouse per day) by gavage administration for 8 weeks. In this study, we evaluated behavior tests, serum biochemical parameters, biomarkers of oxidative stress, and community structure of gut microbiota in mice to explore the potential mechanism of the protective effect. Based on our results, CGA appreciably prevented memory impairment, the release of serum biomarkers, and oxidative stress caused by Pb intake. CGA significantly inhibited Pb-induced increase of cytoplasmic NF-κB, Bax, cytochrome C, and caspase-9 protein expressions. Furthermore, Pb + CGA treatment had a remarkable reversion effect of the gut microbiota composition change induced by Pb, for example increasing the ratio of Helicobacter from 2.95% (Pb) to 11.24% (Pb + CGA) and decreasing the ratio of the Lachnospiraceae_NK4A136_ group from 7.09% (Pb) to 2.68% (Pb + CGA), which suggests that CGA is a superior natural product to eliminate Pb-induced nephrotoxicity and hepatotoxicity.

Abstract
CONTEXT Triptolide (TP) has outstanding biological activities, but it induces toxicities, particular hepatotoxicity, severely limiting its clinical application. Chlorogenic acid (CGA) has prominently medicinal and nutritional values. However, until now, it is not known whether CGA could mitigate TP-induced hepatotoxicity. OBJECTIVE This study explored the possible protection of CGA against TP-induced hepatotoxicity and its potential mechanisms, for the first time. MATERIAL AND METHODS KM mice were treated orally with TP at a single dose of 1 mg/kg at 4 h after being treated with CGA (10, 20 and 40 mg/kg) for seven continuous days. Blood samples were collected at 24 h after TP administration for measurement of serum biomarkers, and hepatic tissues for analysis of potential mechanisms. RESULTS TP treatment-induced acute hepatotoxicity manifested by the significant elevation in serum alanine transaminase (93.9 U/L), aspartate transaminase (185.8 U/L) and hepatic malondialdehyde (0.637 μmol/mg protein), and the remarkable reduction in hepatic glutathione (1.425 μg/mg protein), glutathione S-transferase, glutathione peroxidase, superoxide dismutase and catalase (91.7, 320.7, 360.6 and 140.7 U/mg protein, respectively). In contrast, pretreatment with CGA for 7 days effectively attenuated acute liver injury and oxidative stress caused by TP with each ED50 of 44.4, 57.1, 46.6, 22.2, 40.9, 58.1, 86.4 and 61.0 mg/kg, respectively. Furthermore, pretreatment with CGA promoted the accumulation of Nrf2 into the nucleus, and up-regulated mRNA expression of Nrf2-target downstream genes. DISCUSSION AND CONCLUSIONS Combined CGA medication may probably reduce the risk of TP poisoning, and in-depth mechanisms can be developed around the signal molecules of Nrf2.

Abstract
In this study, Xylose-Taurine reduced (X-T-R) was synthesized to enhance biological activities. Hence, we investigated the hepatoprotective effects of X-T-R against H2O2-induced hepatocyte damage and apoptosis. The results showed that X-T-R led to the cytoprotective effect against H2O2-induced oxidative stress in cultured hepatocytes such as the improvement of cell viability and the reduction of reactive oxygen species (ROS) production. Additionally, pre-treatment with X-T-R increased the expression of nuclear factor erythroid 2-related factor 2 (Nrf2), NAD(P)H dehydrogenase:quinone 1 (NQO1) and heme oxygenase 1 (HO-1) in cultured hepatocytes. Furthermore, X-T-R protected the cells against apoptosis via regulating the expression level of Bcl-2/Bax as well as the activation of caspase-3. According to the results obtained, X-T-R may be a bio-material for the therapy of hepatic diseases.

Abstract
4-tert-octylphenol (OP) is an endocrine-disrupting chemical that causes harmful effects to human health. Chlorogenic acid is the major dietary polyphenol present in various foods and beverages. The aim of the present study was to evaluate the protective role of chlorogenic acid in anemia and mineral disturbance occurring in OP toxicity in rats. Thirty-two male albino rats were divided into four equal groups (8 rats/group) as follows. The first (control) group was treated daily with an oral dose of 1 ml saline for two weeks. The second group was treated daily with an oral dose of 60 mg chlorogenic acid/kg body weight for two weeks. The third and fourth groups received daily intraperitoneal (ip) injections with 100 mg OP/kg body weight for two weeks; the fourth group was treated daily with an oral dose of 60 mg chlorogenic acid/kg body weight for three weeks starting one week before OP injections. The results revealed that OP induced significant decreases in hemoglobin, hematocrit, red blood cells, mean cell volume, mean cell hemoglobin, mean cell hemoglobin concentration, platelet count, white blood cells, lymphocyte and neutrophil percent, transferrin receptor, serum calcium, phosphorous, sodium, potassium, chloride, glutathione-S-transferase, glutathione peroxidase, catalase, glutathione reductase, and superoxide dismutase. Moreover, significant increases in serum hepcidin, ferritin, transferrin, erythropoietin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, urea, creatinine, selenium, zinc, manganese, copper, iron, malondialdehyde, and protein carbonyl levels were found in OP groups. OP exposure also induced cell apoptosis. Chlorogenic acid pretreatment in OP-treated groups restored all the mentioned parameters to approach the normal values. In conclusion, chlorogenic acid protects from anemia and mineral disturbances in 4-tert-octylphenol toxicity by ameliorating oxidative stress and apoptosis.

Abstract
Chlorogenic acid (CGA), an important biologically active dietary polyphenol, is produced by certain plant species and is a major component of coffee. Reduction in the risk of a variety of diseases following CGA consumption has been mentioned in recent basic and clinical research studies. This systematic review discusses in vivo animal and human studies of the physiological and biochemical effects of chlorogenic acids (CGAs) on biomarkers of chronic disease. We searched PubMed, Embase, Amed and Scopus using the following search terms: ("chlorogenic acid" OR "green coffee bean extract") AND (human OR animal) (last performed on April 1st, 2015) for relevant literature on the in vivo effects of CGAs in animal and human models, including clinical trials on cardiovascular, metabolic, cancerogenic, neurological and other functions. After exclusion of editorials and letters, uncontrolled observations, duplicate and not relevant publications the remaining 94 studies have been reviewed. The biological properties of CGA in addition to its antioxidant and anti-inflammatory effects have recently been reported. It is postulated that CGA is able to exert pivotal roles on glucose and lipid metabolism regulation and on the related disorders, e.g. diabetes, cardiovascular disease (CVD), obesity, cancer, and hepatic steatosis. The wide range of potential health benefits of CGA, including its anti-diabetic, anti-carcinogenic, anti-inflammatory and anti-obesity impacts, may provide a non-pharmacological and non-invasive approach for treatment or prevention of some chronic diseases. In this study, the effects of CGAs on different aspects of health by reviewing the related literatures have been discussed.

Abstract
This study is aimed to investigate the inflammation and neurological dysfunction induced by tetrachloro-p-benzoquinone (TCBQ) through Toll-like receptor 4 (TLR4) signaling. We also investigated the protective role of melatonin as an antioxidant and anti-inflammatory agent. In vitro model was established by rat pheochromocytoma PC12 cells, meanwhile, TLR4 wild-type (C57BL/6) and knockout mice (C57BL/10ScNJ TLR4-/-) were used as in vivo model. In vitro study showed TCBQ exposure enhanced the expression of TLR4, myeloid differentiation factor 88 (MyD88) at both transcriptional and post-transcriptional levels. By contrast, melatonin decreased TLR4 and MyD88 expressions. Moreover, our result indicated that melatonin disrupted the formation of TLR4/MyD88/MD2/CD14 complex. In addition, melatonin terminated TCBQ-mediated phosphorylation of c-Jun N-terminal kinase (JNK), p38, and extracellular regulated protein kinase (ERK) signaling and hampered its downstream pro-inflammatory cytokine releases. In vivo result also indicated TLR4 deficiency partially protected against TCBQ-induced morphological and neuropathological changes in mice brain, suggested the role of TLR4. In conclusion, melatonin modulates TCBQ-mediated inflammatory genes through TLR4/MyD88-dependent signaling pathway. Our current study, to the best of our knowledge, is the first time show melatonin not only disrupt the binding of TLR4 and MyD88, but also restricted the formation of TLR4/MD2/CD14 complex, suggesting that melatonin supplementary may represent a valuable therapeutic strategy for inflammatory neurological dysfunction.

Catechol Groups Enable Reactive Oxygen Species Scavenging-Mediated Suppression of PKD-NFkappaB-IL-8 Signaling Pathway by Chlorogenic and Caffeic Acids in Human Intestinal Cells.

Abstract
Chlorogenic acid (CHA) and caffeic acid (CA) are phenolic compounds found in coffee, which inhibit oxidative stress-induced interleukin (IL)-8 production in intestinal epithelial cells, thereby suppressing serious cellular injury and inflammatory intestinal diseases. Therefore, we investigated the anti-inflammatory mechanism of CHA and CA, both of which inhibited hydrogen peroxide (H2O2)-induced IL-8 transcriptional activity. They also significantly suppressed nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) transcriptional activity, nuclear translocation of the p65 subunit, and phosphorylation of IκB kinase (IKK). Additionally, upstream of IKK, protein kinase D (PKD) was also suppressed. Finally, we found that they scavenged H2O2-induced reactive oxygen species (ROS) and the functional moiety responsible for the anti-inflammatory effects of CHA and CA was the catechol group. Therefore, we conclude that the presence of catechol groups in CHA and CA allows scavenging of intracellular ROS, thereby inhibiting H2O2-induced IL-8 production via suppression of PKD-NF-κB signaling in human intestinal epithelial cells.

Abstract
The azo dye o-anisidine is known as an industrial and environmental pollutant. Metabolites of o-anisidine remain in the liver for >24h. However, the toxicological impact of o-anisidine on the liver and its individual cell types, e.g., hepatocytes and immune cells, is currently poorly understood. A novel co-culture system, composed of HepG2 or Huh-7 cells, and differentiated THP-1 cells was used to study the metabolic capacity towards o-anisidine, and compared to primary murine hepatocytes which express high enzyme activities. As model compounds the carcinogenic arylamine o-anisidine and its non-carcinogenic isomer, p-anisidine, as well as caffeine were used. Global proteome analysis revealed an activation of eIF2 and Nrf2-mediated oxidative stress response pathways only in co-cultures after treatment with o-anisidine. This was confirmed via detection of reactive oxygen species. In addition, the mitochondrial membrane potential decreased already after 3h treatment of cells, which correlated with a decrease of ATP levels (R2>0.92). In the supernatant of co-cultured, but not single-cultured HepG2 and Huh-7 cells, o-anisidine caused increases of damage-associated proteins, such as HMGB1 (high mobility group box-1) protein. In summary, only co-cultures of HepG2 and THP-1 cells predict o-anisidine induced stress responsive pathways, since the system has a higher sensitivity compared to single cultured cells.

Abstract
Humans are exposed to a large number of environmental chemicals in their daily life, many of which are readily detectable in blood or urine. It remains uncertain if these chemicals can cause adverse health effects when present together at low doses. In this study we have tested whether a mixture of 27 chemicals administered orally to juvenile male rats for three months could leave a pathophysiological footprint. The mixture contained metals, perfluorinated compounds, PCB, dioxins, pesticides, heterocyclic amines, phthalate, PAHs and others, with a combined dose of 0.16 (Low dose), 0.47 (Mid dose) or 1.6 (High dose) mg/kg bw/day. The lowest dose was designed with the aim of obtaining plasma or urine concentrations in rats at levels approaching those observed in humans. Some single congeners were administered at doses representative of combined doses for chemical groups. With this baseline, we found effects on weight, histology and gene expression in the liver, as well as changes to the blood plasma metabolome in all exposure groups, including low-dose. Additional adverse effects were observed in the higher dosed groups, including enlarged kidneys and alterations to the metabolome. No significant effects on reproductive parameters were observed.

Abstract
Tetrachlorobenzoquinone (TCBQ) is a downstream metabolite of pentachlorophenol (PCP). Previously, we demonstrated that TCBQ caused cytotoxicity due to mitochondrial-related apoptosis. Here, we confirmed the upregulation of death receptor 5 (DR5) followed by the construction of the death-inducing signaling complex (DISC). We also detected the activation of the caspase cascade, which was correlated with TCBQ-induced apoptotic cell death in PC12 cells. The upregulation of DR5 included transcriptional activation and de novo protein synthesis in response to TCBQ. We also identified the endoplasmic reticulum (ER) as a new target for the TCBQ challenge in PC12 cells. The protein kinase R-like ER kinase/eukaryotic translation initiation factor 2α (PERK/eIF2α)-mediated activating transcription factor 4 (ATF4)-ATF3-C/EBP homologous protein (CHOP) signaling pathway contributed to the process of TCBQ-induced ER stress. Blocking ATF4, ATF3, or CHOP signaling by gene silencing technology resulted in decreased cell apoptosis after exposure to TCBQ. Finally, NAC ameliorated TCBQ-induced apoptosis and ER stress, which illustrated that TCBQ-induced apoptosis is somehow ROS-dependent. In summary, this study provided important mechanistic insight into how TCBQ utilizes ER stress-related signaling to exhibit pro-apoptotic activity in PC12 cells.

Abstract
Oxidative stress plays an important role in the pathogenesis of various liver diseases. Safflower yellow B (SYB) has been reported to protect the brain against damage induced by oxidative stress; however, whether SYB can also protect hepatocytes from oxidative stress remains unknown. In the present study, to determine whether pre-treatment with SYB reduces hydrogen peroxide (H2O2)‑induced oxidative stress in HepG2 cells, we investigated H2O2-induced oxidative damage to HepG2 cells treated with or without SYB. Cell viability was measured by MTT assay and cytotoxicity was evaluated by lactate dehydrogenase (LDH) assay. The activities of the antioxidant enzymes, glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) were determined using respective kits. Intracellular reactive oxygen species (ROS) accumulation in the HepG2 cells was monitored using the fluorescent marker, 2',7'-dichlorodihydrofluorescein diacetate (H2DCF-DA). Cell apoptosis was evaluated by determining the activity of caspase-3 and by Annexin V/propidium iodide (PI) double staining. Protein expression levels were measured by western blot analysis, and the levels of related cellular kinases were also determined. H2O2 induced pronounced injury to the HepG2 cells, as evidenced by increased levels of malondialdehyde (MDA) and ROS, the decreased activity of SOD and GSH-Px, the increased activitation of caspase-3 and cell apoptosis, and the loss of mitochondrial membrane potential. SYB significantly inhibited the damaging effects of H2O2, indicating that it protected the cells against H2O2-induced oxidative damage. Moreover, pre-treatment with SYB increased the expression of nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase 1 (HO-1) and NAD(P)H dehydrogenase, quinone 1 (NQO1) which are peroxiredoxins. SYB also significantly increased the phosphorylation of AKT. However, this inductive effect was blunted in the presence of the AKT inhibitor, LY294002. The findings of our study suggest that the activation of the AKT/Nrf2 pathway is involved in the cytoprotective effects of SYB against oxidative stress. Our findings provide new insight into the cytoprotective effects of SYB and the possible mechanisms underlying these effects. Thus, SYB may prove to be of therapeutic value for the treatment of various liver diseases.

ENVIRONMENTAL TOXICOLOGY AND PHARMACOLOGY 2016; 41:241-250. [PMID: 26745386 DOI: 10.1016/j.etap.2015.12.012] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/11/2015] [Revised: 12/17/2015] [Accepted: 12/18/2015] [Indexed: 06/05/2023]
Abstract
Tetrachlorobenzoquinone (TCBQ) is a joint metabolite of persistent organic pollutants (POPs), hexachlorobenzene (HCB) and pentachlorophenol (PCP). Previous studies have been reported that TCBQ contributes to acute hepatic damage due to its pro-oxidative nature. In the current study, TCBQ showed the highest capacity on the cytotoxicity, ROS formation and inflammatory cytokines release among four compounds, i.e., HCB, PCP, tetrachlorohydroquinone (TCHQ, reduced form of TCBQ) and TCBQ, in PC 12 cells. Further mechanistic study illustrated TCBQ activates nuclear factor-kappa B (NF-κB) signaling. The activation of NF-κB was identified by measuring the protein expressions of inhibitor of nuclear factor kappa-B kinase (IKK) α/β, p-IKKα/β, an inhibitor of NF-κB (IκB) α, p-IκBα, NF-κB (p65) and p-p65. The translocation of NF-κB was assessed by Western blotting of p65 in nuclear/cytosolic fractions, electrophoretic mobility shift assay (EMSA) and luciferase reporter gene assay. In addition, TCBQ significantly induced protein and mRNA expressions of inflammatory cytokines and mediators, such as interleukin-1 beta (IL-1β), IL-6, tumor necrosis factor-alpha (TNF-α), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2) and the production of nitric oxide (NO) and prostaglandin E2 (PGE2). Pyrrolidine dithiocarbamate (PDTC), a specific NF-κB inhibitor inhibited these effects efficiently, further suggested TCBQ-induced inflammatory responses involve NF-κB signaling. Moreover, antioxidants, i.e., N-acetyl-l-cysteine (NAC), Vitamin E and curcumin, ameliorated TCBQ-induced ROS generation as well as the activation of NF-κB, which implied that ROS serve as the upstream molecule of NF-κB signaling. In summary, TCBQ exhibits a neurotoxic effect by inducing oxidative stress-mediated inflammatory responses via the activation of IKK/IκB/NF-κB pathway in PC12 cells.

Abstract
Several benzenoid compounds have been isolated from Antrodia camphorata are known to have excellent anti-inflammatory activity. In this study, we investigated the anti-inflammatory potential of 4,7-dimethoxy-5-methyl-1,3-benzodioxole (DMB), one of the major benzenoid compounds isolated from the mycelia of A. camphorata. DMB significantly decreased the LPS-induced production of pro-inflammatory molecules, such as nitric oxide (NO), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) in RAW264.7 cells. In addition, DMB suppressed the protein levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in a dose dependent manner. Moreover, DMB significantly suppressed LPS-induced nuclear translocation of nuclear factor-κB (NF-κB), and this inhibition was found to be associated with decreases in the phosphorylation and degradation of its inhibitor, inhibitory κB-α (IκB-α). Moreover, we found that DMB markedly inhibited the protein expression level of Toll-like receptor 4 (TLR4). Furthermore, treatment with DMB significantly increased hemoxygenase-1 (HO-1) expression in RAW264.7 cells, which is further confirmed by hemin, a HO-1 enhancer, significantly attenuated the LPS-induced pro-inflammatory molecules and iNOS and TLR4 protein levels. Taken together, the present study suggests that DMB may have therapeutic potential for the treatment of inflammatory diseases.

Effects of Bauhinia forficata Tea on Oxidative Stress and Liver Damage in Diabetic Mice. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2015; 2016:8902954.

Abstract
This study was designed to evaluate the effects of Bauhinia forficata Link subsp. pruinosa (BF) tea on oxidative stress and liver damage in streptozotocin (STZ)-induced diabetic mice. Diabetic male mice have remained 30 days without any treatment. BF treatment started on day 31 and continued for 21 days as a drinking-water substitute. We evaluated (1) BF chemical composition; (2) glucose levels; (3) liver/body weight ratio and liver transaminases; (4) reactive oxygen species (ROS), lipid peroxidation, and protein carbonylation in liver; (5) superoxide dismutase (SOD) and catalase (CAT) activities in liver; (6) δ-aminolevulinate dehydratase (δ-ALA-D) and nonprotein thiols (NPSH) in liver; (7) Nrf2, NQO-1, and HSP70 levels in liver and pancreas. Phytochemical analyses identified four phenols compounds. Diabetic mice present high levels of NQO-1 in pancreas, increased levels of ROS and lipid peroxidation in liver, and decrease in CAT activity. BF treatment normalized all these parameters. BF did not normalize hyperglycemia, liver/body weight ratio, aspartate aminotransferase, protein carbonyl, NPSH levels, and δ-ALA-D activity. The raised oxidative stress seems to be a potential mechanism involved in liver damage in hyperglycemic conditions. Our results indicated that BF protective effect could be attributed to its antioxidant capacity, more than a hypoglycemic potential.

Abstract
Supplemental Digital Content is available in the text. There is an urgent need to search for novel chemosensitizers in the field of cancer therapy. Chlorogenic acid (CGA), a type of polyphenol present in the diet, has many biological activities. The present study is designed to explore the influence of CGA on the effects of 5-fluorouracil (5-FU) on human hepatocellular carcinoma cells (HepG2 and Hep3B). Treatment with 5-FU induced the inhibition of hepatocellular carcinoma cells’ proliferation, and the combined treatment with CGA enhanced this inhibition. 5-FU also increased the production of reactive oxygen species (ROS). The combination of 5-FU and CGA led to a more prominent production of ROS and significantly inactivated ERK1/2, although CGA and 5-FU exerted no significant changes when used alone. A previous report has shown that ROS are upstream mediators that inactivate ERK in hepatocellular carcinoma cells. Combined with our results, this indicates that the combination of 5-FU and CGA leads to the inactivation of ERK through the overproduction of ROS. This mediates the enhancement of 5-FU-induced inhibition of hepatocellular carcinoma cells’ proliferation, that is, CGA sensitizes hepatocellular carcinoma cells to 5-FU treatment by the suppression of ERK activation through the overproduction of ROS. CGA has shown potential as a chemosensitizer of 5-FU chemotherapy in hepatocellular carcinoma.

Abstract
Chlorogenic acid (CGA) has been reported to prevent acetaminophen (AP)-induced hepatotoxicity when mice were pre-administered orally with CGA for consecutive 7days before AP intoxication in our previous study. This study investigated the therapeutic detoxification of CGA against AP-induced hepatotoxicity and the engaged mechanism. The mice were orally administered with CGA (10, 20, 40mg/kg) at 1h after given AP (400mg/kg), and another 3h later the mice were killed for the following experiments. Results of serum transaminases analysis and histological evaluation demonstrated the detoxification of CGA against AP-induced hepatotoxicity. CGA reduced AP-induced the increased myeloperoxidase (MPO) enzymatic activity and its expression. CGA reduced AP-induced the increased liver expression of toll-like receptor (TLR)-3/4 and MyD88, and the increased phosphorylation of inhibitor of kappa B (IκB) and p65 subunit of nuclear factor κB (NFκB). CGA reduced AP-induced the increased NFκBp65 expression in nucleus. In addition, CGA reduced AP-induced the increased serum levels and liver mRNA expression of tumor necrosis factor alpha (TNFα), interleukin (IL)-1β, IL-6, monocyte chemoattractant protein-1 (MCP-1), and keratinocyte chemoattractant (KC). Taken together, our results demonstrate the therapeutic detoxification of CGA against AP-induced liver injury, and TLR3/4 and NFκB signaling pathway are involved in such process.

Abstract
The present study aimed to investigate the protective effects of luteolin (L), chlorogenic acid (ChlA) and caffeic acid (CafA) against cyto-genotoxic effects caused by OTA. Vero cells and rat lymphocytes were used and viability was measured by neutral red uptake, MTT and trypan blue dye exclusion method. L (50 and 100μg/mL), ChlA (100 and 200μg/mL) and CafA (10-50μg/mL) reduced the damage induced by OTA (10μg/mL) on both cells type shown a good protective effect. The comet and micronucleus tests in Balb/c mice were performed. ChlA (10mg/kg bw) reduced OTA (0.85mg/kg bw)-induced DNA damage on blood and bone marrow cells, CafA (10mg/kg bw) showed protective effect only in blood cells and luteolin (2.5mg/kg bw) failed to protect DNA integrity on cells. In conclusion, polyphenols tested reduced the toxicity caused by OTA on different target cells with good protective effect, being ChlA the compound that showed the best effects.
