[PMID: 38589968 PMCID: PMC11000351 DOI: 10.1186/s42826-024-00200-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 03/14/2024] [Accepted: 03/20/2024] [Indexed: 04/10/2024] Open
Abstract
BACKGROUND Gastrodia elata Blume (GEB), a traditional medicinal herb, has been reported to have pharmacological effect including protection against liver, neuron and kidney toxicity. However, explanation of its underlying mechanisms remains a great challenge. This study investigated the protective effects of GEB extract on vancomycin (VAN)-induced nephrotoxicity in rats and underlying mechanisms with emphasis on the anti-oxidative stress, anti-inflammation and anti-apoptosis. The male Sprague-Dawley rats were randomly divided three groups: control (CON) group, VAN group and GEB group with duration of 14 days. RESULTS The kidney weight and the serum levels of blood urea nitrogen and creatinine in the GEB group were lower than the VAN group. Histological analysis using hematoxylin & eosin and periodic acid Schiff staining revealed pathological changes of the VAN group. Immunohistochemical analysis revealed that the expression levels of N-acetyl-D-glucosaminidase, myeloperoxidase and tumor necrosis factor-alpha in the GEB group were decreased when compared with the VAN group. The number of terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling-positive cells, phosphohistone and malondialdehyde levels were lower in the GEB group than VAN group. The levels of total glutathione in the GEB group were higher than the VAN group. CONCLUSIONS The findings of this study suggested that GEB extract prevents VAN-induced renal tissue damage through anti-oxidation, anti-inflammation and anti-apoptosis.

Rani J, Dhull SB, Rose PK, Kidwai MK. Drug-induced liver injury and anti-hepatotoxic effect of herbal compounds: a metabolic mechanism perspective. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 122:155142. [PMID: 37913641 DOI: 10.1016/j.phymed.2023.155142] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 09/27/2023] [Accepted: 10/10/2023] [Indexed: 11/03/2023]
Abstract
BACKGROUND Drug-induced liver injury (DILI) is the most challenging and thought-provoking liver problem for hepatologists owing to unregulated medication usage in medical practices, nutritional supplements, and botanicals. Due to underreporting, analysis, and identification issues, clinically evaluated medication hepatotoxicity is prevalent yet hard to quantify. PURPOSE This review's primary objective is to thoroughly compare pharmaceutical drugs and herbal compounds that have undergone clinical trials, focusing on their metabolic mechanisms contributing to the onset of liver illnesses and their hepatoprotective effects. METHODS The data was gathered from several online sources, such as PubMed, Scopus, Google Scholar, and Web of Science, using appropriate keywords. RESULTS The prevalence of conventional and herbal medicine is rising. A comprehensive understanding of the metabolic mechanism is necessary to mitigate the hepatotoxicity induced by drugs and facilitate the incorporation or substitution of herbal medicine instead of pharmaceuticals. Moreover, pre-clinical pharmacological research has the potential to facilitate the development of natural products as therapeutic agents, displaying promising possibilities for their eventual clinical implementation. CONCLUSIONS Acetaminophen, isoniazid, rifampicin, diclofenac, and pyrogallol have been identified as the most often reported synthetic drugs that produce hepatotoxicity by oxidative stress, inflammation, apoptosis, and fibrosis during the last several decades. Due to their ability to downregulate many factors (such as cytokines) and activate several enzyme/enzyme systems, herbal substances (such as Gingko biloba extract, curcumin, resveratrol, and silymarin) provide superior protection against harmful mechanisms which induce hepatotoxicity with fewer adverse effects than their synthetic counterparts.

Abstract
Based on DNA bio-dots-induced aggregation of gold nanoparticles (AuNPs), a methionine (Met) photoelectrochemical (PEC) sensor with CS-GSH-CuNCs/TiO2 NPs as the photoelectric conversion element and AuNPs as the specific recognition element was constructed. First, a TiO2 NPs/ITO electrode and CS-GSH-CuNCs were prepared, and then the CS-GSH-CuNCs/TiO2 NPs/ITO photosensitive electrode was obtained by self-assembly. Next, DNA bio-dots were modified to the upper surface of the electrode using a coupling reaction to assemble the DNA bio-dots/CS-GSH-CuNCs/TiO2 NPs electrode. Amino-rich DNA bio-dots were used to induce the aggregation of AuNPs on the electrode surface via Au-N interactions and prepare the AuNPs/DNA bio-dots/CS-GSH-CuNCs/TiO2 NPs electrode. Due to the fluorescence resonance energy transfer (FRET) between CS-GSH-CuNCs and AuNPs, the complexation chance of electron-hole (e--h+) pair in CS-GSH-CuNCs increased, which, in turn, led to a decrease in photocurrent intensity. When Met was present, AuNPs aggregated on the electrode surface were shed and bound to Met since the Au-S interaction is stronger than the Au-N interaction, resulting in the recovery of the photocurrent signal. Under optimal conditions, the photocurrent intensity of the PEC sensor showed good linearity with the logarithm of Met concentration in the range of 25.0 nmol/L-10.0 μmol/L with the limit of detection (LOD) of 5.1 nmol/L (S/N = 3, n = 10).

Abstract
Danshen, also known as Salvia miltiorrhiza, is a medicinal herb used in traditional Chinese medicine. Its potential impact on endometrial cancer has not been thoroughly investigated. This study aimed to examine the effect of dihydroisotanshinone I (DT), a compound found in Danshen, on the viability of ARK1 and ARK2 endometrial cancer cells and its mechanisms. The results showed that 10 μM DT inhibited cell viability of ARK1 and ARK2 cells by inducing apoptosis and ferroptosis, which was achieved by blocking the expression of GPX4. In vivo experiments using a xenograft nude mouse model indicated that DT treatment significantly reduced tumor volume without causing any adverse effects. These findings suggest that DT may be a potential therapeutic agent for inhibiting endometrial cancer cell viability, but further research is needed to confirm these results.

Podocin, mTOR, and CHOP dysregulation contributes to nephrotoxicity induced of lipopolysaccharide/diclofenac combination in rats: Curcumin and silymarin could afford protective effect. Life Sci 2023; 330:121996. [PMID: 37536613 DOI: 10.1016/j.lfs.2023.121996] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Revised: 07/22/2023] [Accepted: 07/31/2023] [Indexed: 08/05/2023]
Abstract
AIM Sepsis is a common cause of acute kidney injury (AKI). Lipopolysaccharides (LPS) are the main gram-negative bacterial cell wall component with a well-documented inflammatory impact. Diclofenac (DIC) is a non-steroidal anti-inflammatory drug with a potential nephrotoxic effect. Curcumin (CUR) and silymarin (SY) are natural products with a wide range of pharmacological activities, including antioxidant and anti-inflammatory ones. The objective of this study was to examine the protective impact of CUR and SY against kidney damage induced by LPS/DIC co-exposure. MATERIALS AND METHODS Four groups of rats were used; control; LPS/DIC, LPS/DIC + CUR, and LPS/DIC + SY group. LPS/DIC combination induced renal injury at an LPS dose much lower than a nephrotoxic one. KEY FINDING Nephrotoxicity was confirmed by histopathological examination and significant elevation of renal function markers. LPS/DIC induced oxidative stress in renal tissues, evidenced by decreasing reduced glutathione and superoxide dismutase, and increasing lipid peroxidation. Inflammatory response of LPS/DIC was associated with a significant increase of renal IL-1β and TNF-α. Treatment with either CUR or SY shifted measured parameters to the opposite side. Moreover, LPS/DIC exposure was associated with upregulation of mTOR and endoplasmic reticulum stress protein (CHOP) and downregulation of podocin These effects were accompanied by reduced gene expression of cystatin C and KIM-1. CUR and SY ameliorated LPS/DIC effect on the aforementioned genes and protein significantly. SIGNIFICANCE This study confirms the potential nephrotoxicity; mechanisms include upregulation of mTOR, CHOP, cystatin C, and KIM-1 and downregulation of podocin. Moreover, both CUR and SY are promising nephroprotective products against LPS/DIC co-exposure.

Abstract
BACKGROUND Cyclophosphamide use has been associated with increased oxidative stress in cells and tissues. Quercetin's antioxidative properties make it of potential benefit in such conditions of oxidative stress. OBJECTIVE To assess quercetin's ability to mitigate cyclophosphamide-induced organ toxicities in rats. METHODS Sixty rats were assigned into six groups. Groups A and D served as normal and cyclophosphamide control and were fed standard rat chow, groups B and E were fed quercetin supplemented diet (100 mg/kg of feed), while those in groups C and F were fed quercetin at 200 mg/kg of feed. Groups A-C received intraperitoneal (ip) normal saline on days 1 and 2, while D-F received ip cyclophosphamide (150 mg/kg/day on days 1 and 2). On day 21, behavioural tests were carried out, animals were sacrificed and blood samples taken. Organs were processed for histological study. RESULTS Quercetin reversed cyclophosphamide-induced decrease in body weight, food intake and total antioxidant capacity, and increase in lipid peroxidation (p = 0.001), It also reversed derangement in levels of liver transaminase, urea, creatinine and proinflammatory cytokines (p = 0.001). Improvement in working-memory and anxiety-related behaviours were also observed. Finally, quercetin reversed alterations in levels of acetylcholine, dopamine and brain-derived neurotropic factor (p = 0.021); while reducing serotonin levels and astrocyte immunoreactivity. CONCLUSION Quercetin shows significant ability to protect against cyclophosphamide-induced changes in rats.

Silymarin Protects against Acute Liver Injury Induced by Acetaminophen by Downregulating the Expression and Activity of the CYP2E1 Enzyme. MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27248855. [PMID: 36557984 PMCID: PMC9784215 DOI: 10.3390/molecules27248855] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 12/03/2022] [Accepted: 12/10/2022] [Indexed: 12/15/2022]
Abstract
Previous studies have shown that silymarin protects against various types of drug-induced liver injury, but whether the protective mechanism of silymarin against acetaminophen-induced liver injury is related to the CYP2E1 enzyme remains unclear. In this study, we investigated the effect of silymarin on the activity and expression of CYP2E1 in vitro and in vivo. The results of in vitro studies showed that silymarin not only inhibited the activity of CYP2E1 in human and rat liver microsomes but also reduced the expression of CYP2E1 in HepG2 cells. In vivo studies showed that silymarin pretreatment significantly reduced the conversion of chlorzoxazone to its metabolite 6-OH-CLX and significantly increased the t1/2, area under the curve (AUC) and mean residence time (MRT) of chlorzoxazone. In addition, silymarin pretreatment significantly inhibited the upregulation of Cyp2e1 expression, reduced the production of 3-cysteinylacetaminophen trifluoroacetic acid salt (APAP-CYS), and restored the liver glutathione level. The results of our study show that silymarin plays an important protective role in the early stage of acetaminophen-induced acute liver injury by reducing the activity and expression of CYP2E1, reducing the generation of toxic metabolites, and alleviating liver injury.

Abstract
BACKGROUND Currently, there is increasing advocacy for the use of diet, dietary supplements, and herbal remedies in depression management.
AIM To determine the antidepressant effects of standardized silymarin (SILY) extract either as a sole agent or as an adjunct in depression therapy.
METHODS Adult mice were assigned into three main groups based on the neurobehavioural models; and each main group had ten treatment groups of 10 mice each. Treatment groups were: Vehicle control group, oral sertraline (SERT) group, two groups fed SILY)-supplemented diet (SILY at 140 and 280 mg/kg of feed, respectively), dexamethasone (DEX; i.p.) group, DEX/SERT group, two groups of DEX/SILY (SILY at 140 and 280 mg/kg of feed, respectively), and another two groups of (SERT/DEX/SILY) (SILY at 140 and 280 mg/kg of feed, respectively, plus i.p. DEX plus SERT). Duration of the study was 7 wk, and treatments were administered daily.
RESULTS SILY (alone) increased body weight, open field locomotor activity, rearing, and grooming; it also enhanced spatial working memory while decreasing anxiety-related behaviours and behavioural despair. SILY also improved antioxidant status while decreasing lipid peroxidation, acetylcholinesterase activity, and inflammatory markers. Neuronal integrity of the cerebral cortex and hippocampus was preserved. Overall, when administered alone or with SERT, SILY counteracted DEX-induced behavioural and biochemical changes while preserving neuromorphological integrity.
CONCLUSION In conclusion, SILY is beneficial in mitigating DEX-induced central nervous system and other related changes in mice.

Abstract
It's known that APAP overdose often leads to hepatotoxicity and nephrotoxicity. In the present study, we investigated the preventative effect of Tan IIA on APAP-induced nephrotoxicity. Mice were orally administrated with Tan IIA (10 or 30 mg/kg/day) for 1 week and subsequently gavaged with 200 mg/kg of APAP. Tan IIA reduced APAP-induced nephrotoxicity as evidenced by histopathological evaluation and serum creatinine levels. Tan IIA pretreatment promoted the efflux of the toxic intermediate metabolite N-acetyl-p-benzoquinone imine (NAPQI), thus reduced its injury to mouse kidney. After Tan IIA pretreatment, a remarkable increase in mRNA and protein expression of Nrf2 and its target genes Mrp2 and Mrp4 was observed in Nrf2+/+ mice kidneys, however, no obvious change of Mrp2 and Mrp4 mRNA and protein expression was detected in Nrf2-/- mice kidneys. HK-2 cells were used for exploring the roles of Tan IIA in the Nrf2-MRPs pathway in vitro. Consistently, Tan IIA up-regulated the Nrf2-MRPs pathway and promoted the nuclear Nrf2 accumulation in HK-2 cells. Collectively, our findings suggested that Tan IIA facilitated the clearance of toxic intermediate metabolite NAPQI from the kidney through upregulation of the Nrf2-MRP2/4 pathway, thereby, performing preventive effects against APAP-induced nephrotoxicity.

In this study, we found that dihydroisotanshinone I (DT), a pure compound extracted from danshen, can inhibit the growth of A549 cells and H460 cells. DT also induced apoptosis and ferroptosis in these lung cancer cells. DT also blocking the protein expression of GPX4 (Glutathione peroxidase 4). For in vivo study, DT treatment can inhibit metastasis of A549 cells in the nude mice model without adverse effects on mice. In conclusion, DT inhibited the growth of lung cancer cells through apoptosis and ferroptosis and inhibited metastasis of A549 cells in the nude mice model. Further studies are warranted to validate the findings of this study.

Lasting effects of ketamine and isoflurane administration on anxiety- and panic-like behavioral responses in Wistar rats. Life Sci 2021; 276:119423. [PMID: 33785344 DOI: 10.1016/j.lfs.2021.119423] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Revised: 03/18/2021] [Accepted: 03/20/2021] [Indexed: 10/21/2022]
Abstract
In clinical and laboratory practice, the use of anesthetics is essential in order to perform surgeries. Anesthetics, besides causing sedation and muscle relaxation, promote several physiological outcomes, such as psychotomimetic alterations, increased heart rate, and blood pressure. However, studies depicting the behavioral effect induced by ketamine and isoflurane are conflicting. In the present study, we assessed the behavioral effects precipitated by ketamine and isoflurane administration. We have also evaluated the ketamine effect on cell cytotoxicity and viability in an amygdalar neuronal primary cell culture. Ketamine (80 mg/kg) caused an anxiogenic effect in rats exposed to the elevated T-maze test (ETM) 2 and 7 days after ketamine administration. Ketamine (40 and 80 mg/kg) administration also decreased panic-like behavior in the ETM. In the light/dark test, ketamine had an anxiogenic effect. Isoflurane did not change animal behavior on the ETM. Neither ketamine nor isoflurane changed the spontaneous locomotor activity in the open field test. However, isoflurane-treated animals explored less frequently the OF central area seven days after treatment. Neither anesthetic caused oxidative damage in the liver. Ketamine also reduced cellular metabolism and led to neuronal death in amygdalar primary cell cultures. Thus, our work provides evidence that ketamine and isoflurane induce pronounced long lasting anxiety-related behaviors in male rats.

Abstract
Madhuca longifolia, a tropical tree used as medicine and food, is known to have a beneficial effect against stomach gastric toxicity. Madhuca longifolia is used in treating cough, skin disease and nerve disorders. Diclofenac, a non-steroidal anti-inflammatory drug (NSAID), with overdosage and prolonged use, is known to cause gastric toxicity. Silymarin (SLY), a polyphenolic antioxidant flavonoid, is a derivative of Silybum marianum extracted from milk thistle seeds and fruits, has been widely used in the treatment of gastric ulcer. SLY was used as the standard drug to compare the effects with the Madhuca longifolia aqueous leaf extract treatment. The aim of the current study is to understand the effect of Madhuca longifolia aq. leaf extract on rat stomach and intestine against diclofenac-administered toxicity. Rats (n = 30) were divided into Group I normal control, Group II treated with diclofenac, Group III treated with diclofenac and Madhuca longifolia leaf extract, Group IV treated with diclofenac and silymarin, and Group V was treated with Madhuca longifolia leaf extract alone. After the study duration, rats were euthanized and tissue samples were analyzed for antioxidant, cytokine, protein expression levels and histopathological changes. Diclofenac treated rats had significant (p < 0.05) changes in levels of antioxidants, cytokines, protein expression and pathological changes as compared to rats treated with Madhuca longifolia. This study demonstrated that Madhuca longifolia leaf extract had gastroprotective activity in rats treated with diclofenac.

Abstract
Drug-induced liver injury (DILI) is a frequent cause responsible for acute liver failure (ALF). Acetaminophen (APAP) is a known hepatotoxin predictably causing intrinsic DILI. At high doses, APAP causes acute liver necrosis and responsible for ALF and liver transplant cases in 50% and 20% of patients, respectively, in the United States alone. Oxidative stress and glutathione depletion are implicated in APAP-induced liver necrosis. Boldine, a plant-derived compound is shown to have promising antioxidant potential. Therefore, this study investigates the protective effect of boldine against APAP-induced acute hepatic necrosis in mice. A single toxic dose of APAP (300 mg/kg b.w. p.o.) was administered in overnight-fasted mice to induce acute liver necrosis. Separately, APAP + boldine and APAP + N-acetylcysteine (NAC) simultaneous treatments were also given. Serum transaminases and reduced glutathione, enzymic antioxidants, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and, IL-6 were evaluated in liver tissue. Acute APAP intoxication significantly elevated serum marker enzymes of hepatotoxicity. APAP administration increased lipid peroxidation, TNF-α, IL-1β, and IL-6 protein expressions. The enzymic antioxidants and reduced glutathione levels were decreased in liver tissue of APAP intoxicated mice. Boldine and NAC simultaneous treatments prevented APAP-induced oxidative stress, inflammation, and necrosis. The results of this study suggest the crucial role of boldine to protect against APAP induced hepatotoxicity by virtue of its antioxidant and anti-inflammatory properties.

Abstract
Acetaminophen (APAP) is one of the few recommended analgesic and antipyretic drugs in some critical cases such as viral disease COVID-19. However, the unrestricted use of APAP develops liver disorders. Hepatotoxicity and liver injury can also be induced by ionizing radiation (IR) during radiotherapy. The data of the current study represents that treatment of rats with either APAP-overdose, or gamma-irradiation (R) induces hepatotoxicity, results in significant increases of the hepatic-enzymes activities (ALT, AST, ALP, GGT, LDH, and MDH), as well as enhancement of triglycerides, total cholesterol levels, combined with declines in albumin and total protein contents. An enhancement of the lipid peroxides (malondialdehyde; MDA), and nitric oxide levels along with a decline of reduced glutathione contents and suppression of superoxide dismutase, catalase, and glutathione peroxidase activities are also observed within the liver tissues of intoxicated animals. TNF-α, IL-1β, IL-6, iNOS, Cytochrome P450 2E1 (CYP2E1), miR-802 gene expression, NF-κB, and calcium levels are up-regulated, while Nuclear factor erythroid-related factor-2 (Nrf2), Hemoxygenase-1 (HO-1) protein and gene expressions, as well as, glutamate-cysteine ligase catalytic subunit (GCLC), NAD(P)H-Quinone oxidoreductase (NQO1), and miR-122 gene expressions are down-regulated in the livers of intoxicated animals. All these parameters show significant improvement in R/APAP intoxicated animals. Curcumin pretreatment develops an amelioration of these effects in APAP-overdose, R-exposure, or R/APAP treatments. In conclusion, oral administration of curcumin shows hepatoprotective effects against APAP-overdose induced hepatic damage in normal and gamma-irradiated rats through prospective regulation of the therapeutic targets CYP2E1, Nrf2, and NF-κB, via organizing the miR-122 and miR-802 gene expression.

Abstract
The objective of this study was to evaluate the effects of arginine (ARG) and/or lysine (LYS) supplementation on meat quality and oxidative stability of beef loins. Steers (n = 40) were split among four dietary treatments (control, ARG, LYS or ARGLYS). The loins (longissimus lumborum) were obtained at 1 day postmortem and aged either 14 or 28 days prior to cutting of steaks for 7 days of display. No impacts of diet treatments on instrumental tenderness, water-holding capacity and fatty acid profiles were found (P > 0.05). Extended aging significantly decreased lipid oxidative stability, color stability and reducing ability of loins. However, steaks from ARG and ARGLYS maintained superior color stability coupled with lower mitochondrial membrane permeability and higher cytochrome c redox stability compared to control (P < 0.05). These results indicate that ARG supplementation can improve color stability of beef loins possibly through delayed onset of mitochondrial-mediated apoptotic processes.

Abstract
BACKGROUND Metabolic syndrome is a complex pattern of disorders that occur jointly and is associated with an increased risk of cardiovascular and cerebrovascular disease. Therefore the need for more-efficient options of treatment has become imperative. OBJECTIVE This study examined the effect of dietary-melatonin in the management of behavioural, metabolic, antioxidant, and organ changes due to high-fat/high-sugar (HFHS) diet-induced metabolic syndrome in mice. METHODS Mice were randomly assigned into five groups of ten animals each. Groups were normal control [fed standard diet (SD)], HFHS control, and 3 groups of melatonin incorporated into HFHS at 2.5, 5, and 10 mg/kg of feed. Mice were fed for seven weeks, and body weight was assessed weekly. Open-field behaviours, radial-arm, and Y-maze spatial memory were scored at the end of the experimental period. Twenty-four hours after the last behavioural test, blood was taken for estimation of blood glucose levels after an overnight fast. Animals were then euthanised, and blood was taken for estimation of plasma insulin, leptin, and adiponectin levels, and serum lipid profile. The liver, kidneys, and brain were excised and processed for general histology, while homogenates of the liver and whole brain were used to assess oxidative stress parameters. RESULTS Results showed that dietary melatonin (compared to HFHS diet) was associated with a decrease in body weight, food intake, and novelty-induced behaviours; and an increase in spatial-working memory scores. A decrease in glucose, insulin, leptin, and malondialdehyde levels; and an increase in adiponectin levels and superoxide dismutase activity were also observed. Histomorphological/ histomorphometric examination revealed evidence of organ injury with HFHS diet, and varying degrees of amelioration with melatonin-supplemented diet. CONCLUSION In conclusion, dietary melatonin supplementation may have beneficial effects in the management of the metabolic syndrome.

Abstract
BACKGROUND Azodicarbonamide is a dough-enhancer used in the process of breadmaking in countries like Nigeria. While there have been suggestions that it is a sensitizer of the respiratory system, there is a dearth of information on its effects on the central nervous system. AIM This study assessed the effects of azodicarbonamide on the central nervous system (ADA) in rats. OBJECTIVE The effects of ADA-containing diet on neurobehaviour, brain antioxidant status, and neuromorphology of selected brain regions in rats were examined. METHODS Forty adult rats were randomly-assigned into four groups of ten rats each, and were given standard diet or diet containing ADA at 1, 2 and 4% respectively. Rats were fed a standard diet or ADA-containing diet for a period of 28 days. Weekly body weight assessment and daily estimation of food intake were done. Behavioural tests {in the Open field, Y-maze, radial-arm maze, and Elevated Plus Maze (EPM)} were conducted on day 29. Twenty-four hours after the last behavioural test, animals were euthanised, whole brains were dissected, weighed, and either homogenised for assessment of lipid peroxidation and antioxidant status; or sectioned and processed for general histology. RESULTS Consumption of ADA-containing diet was associated with a significant decrease in weight gain/food intake, and significant suppression of horizontal locomotion and rearing behaviours; however, grooming activity increased significantly. Also, there was a significant reduction of open-arm time in the EPM and a significant increase in Y-maze alternation (at the lowest concentration of ADA). ADA-containing diet was not associated with significant changes in brain oxidative status or neuromorphology. CONCLUSION The study showed that while ADA-containing diet may alter neurobehaviour in rats; this was not associated with evidence of brain oxidative stress or neuro-histomorphological alterations.

Abstract
BACKGROUND Diclofenac is commonly prescribed Non-Steroidal Anti-Inflammatory Drug (NSAIDs) as it has anti-inflammatory, analgesic and anti-pyretic properties. Long term usage and over-dosage of diclofenac is associated with adverse effects like drug-induced liver injury, gastrointestinal and renal toxicity. The therapeutic uses of medicinal plants have gained a prominent role in recent years. Madhuca longifolia is a tree found throughout India, which is known to have several pharmacological activities. The aim of our study is to investigate the potential effect of the ethanolic and methanolic leaf extracts of M. longifolia against diclofenac-induced toxicity. METHODS The rats used for the experiment were divided into seven groups. Group-1 was the normal control. Group-2 was administered with diclofenac (50 mg/kg b.w./day/ip) on the 4th and the 5th day. Group-3 was treated with diclofenac and ELEML (500 mg/kg b.w./day/po) on all 5 days. Group-4 was treated with diclofenac and MLEML (500 mg/kg b.w./day/po) on all 5 days. Standard drug silymarin (25 mg/kg b.w./day/po) was given to the rats of group-5 along with diclofenac. Group-6 and group-7 were treated with ethanolic leaf extract and methanolic leaf extract of M. longifolia respectively. After the study period, the rats were evaluated for parameters like liver and renal markers, antioxidants and histopathological changes. RESULTS This study has proved the beneficial effect of ethanolic and methanolic leaf extract of M. longifolia against diclofenac-induced toxicity wherein ethanolic leaf extract showed a better result than methanolic leaf extract. CONCLUSION Our study has concluded the beneficial effect of ethanolic and methonolic leaf extract of Madhuca longifolia against DFC-induced toxicity. This study proves that it has potential effect on hepato, renal and gastro toxicity in female Wistar albino rats. It can further be studied to understand its mechanism in treating toxicity.

Abstract
Danshen (salvia miltiorrhiza Bunge) is widely used in traditional Chinese medicine. However, it is definite clinical effort and mechanism on breast cancer is unclear. In our study, we used the real-world database to investigate in vivo protective effort of danshen in the breast cancer patients through using population-based data from the Taiwan National Health Insurance Research Database (NHIRD). In vitro, human breast cancer cells (MCF-7 cells and MDA-MB-231 cells) were used to investigate the effect and the underlying mechanism through XTT assay, flow cytometry, glutathione peroxidase (GPX) activity assay, GSH (reduced glutathione)/GSSG (oxidized glutathione), malondialdehyde (MDA), and western blot analysis. The in vivo effect was investigated through a xenograft nude mouse model. We found that dihydroisotanshinone I (DT), a pure compound present in danshen, can inhibit the growth of breast carcinoma cells, including MCF-7 cells and MDA-MB-231 cells. Moreover, DT induced apoptosis and ferroptosis in these breast cancer cells. DT also repressed the protein expression of GPX4 (Glutathione peroxidase 4). For in vivo study, DT treatment also significantly inhibited the final tumor volume without adverse effects in a xenograft nude mouse model. In conclusion, danshen has protective efforts in breast cancer patients, which could be attributed to DT through inducing apoptosis and ferroptosis of breast cancer cells.

Wang Z, Liang M, Li H, Cai L, He H, Wu Q, Yang L. l-Methionine activates Nrf2-ARE pathway to induce endogenous antioxidant activity for depressing ROS-derived oxidative stress in growing rats. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2019; 99:4849-4862. [PMID: 31001831 DOI: 10.1002/jsfa.9757] [Citation(s) in RCA: 42] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/10/2018] [Revised: 04/08/2019] [Accepted: 04/10/2019] [Indexed: 06/09/2023]
Abstract
BACKGROUND Methionine is an essential sulfur-containing amino acid. To elucidate the influence of l-methionine on activation of the nuclear factor erythroid 2-related factor 2-antioxidant responsive element (Nrf2-ARE) antioxidant pathway to stimulate the endogenous antioxidant activity for depressing reactive oxygen species (ROS)-derived oxidative stress, male Wistar rats were orally administered l-methionine daily for 14 days. RESULTS With the intake of l-methionine, Nrf2 was activated by l-methionine through depressing Keap1 and Cul3, resulting in upregulation of ARE-driven antioxidant expression (glutamate cysteine ligase catalytic subunit, glutamate cysteine ligase modulatory subunit, glutathione synthase (GS), catalase (CAT), superoxide dismutase (SOD), heme oxygenase 1, NAD(P)H:quinone oxidoreductase 1, glutathione reductase (GR), glutathione S-transferase (GST), glutathione peroxidase (GPx)) with increasing l-methionine availability. Upon activation of Nrf2, glutathione synthesis was increased through upregulated expression of methionine adenosyltransferase, S-adenosylhomocysteine hydrolase, cystathionine β-synthase, cystathionine γ-lyse, glutamate cysteine ligase (GCL) and GS, while hepatic expressions of methionine sulfoxide reductases (MsrA, MsrB2, MsrB3) and hepatic enzyme activities (CAT, SOD, GCL, GR, GST, GPx) were uniformly stimulated with increasing consumption of l-methionine. As a result, hepatic content of ROS and MDA were effectively reduced by l-methionine intake. CONCLUSION The present study demonstrates that methionine availability plays a critical role in activation of the Nrf2-ARE pathway to induce an endogenous antioxidant response for depressing ROS-derived oxidative stress, which is primarily attributed to the stimulation of methionine sulfoxide reductase expression and glutathione synthesis. © 2019 Society of Chemical Industry.

Abstract
Context: Overconsumption of paracetamol (PAR) and diclofenac (DF) have been reported to induce neurotoxicity and endocrine disruption. Objective: The current study was designed to explore the protective potential of betanin against PAR and DF inducing neurotoxicity and endocrine disruption in a rat model. Material and Methods: Forty rats were equally divided into five groups: group I served as control, group II received PAR (400 mg/kg), group III received PAR plus betanin (25 mg/kg), group IV received DF (10 mg/kg) and group V received DF plus betanin orally for 28 consecutive days. Thyroid axis hormones, sex hormone, neurotransmitters, paraoxonase-1, hemeoxygenase-1 and nuclear factor-2 were measured by ELISA. While, the oxidative stress markers were colorimetrically estimated. Moreover, DNA damage and histopathological picture of the brains were investigated. Results: A marked reduction in thyroid axis hormones, brain neurotransmitters and serum testosterone as well as enhanced oxidative stress and brain DNA damage accompanied by drastic changes in the brain histopathological picture were recorded in the challenged PAR and DF groups. Betanin supplementation ameliorated most of the biochemical and histopathological changes induced by PAR or DF. Conclusion: The study suggests betanin of potential protective effects against neurotoxicity and endocrine disruption induced by PAR and DF overconsumption.

Abstract
Ketamine is a dissociative anaesthetic agent whose recreational use amongst adolescents and young adults is reaching epidemic proportions in a number of countries. While animal studies have examined the long-term detrimental effects of early-life ketamine exposure, there is a paucity of information on the immediate effects of ketamine following subchronic administration in the adolescence period. Adolescent rats were assigned into four groups of 10 animals each, administered intraperitoneal (i.p) injections of vehicle or one of three doses of ketamine (7.5, 15 or 30 mg/kg daily) for 8 weeks, and then exposed to behavioural paradigms. Rats were then euthanised after an overnight fast, and blood taken was used for measurement of metabolic indices. The brains were dissected out and either homogenised for estimation of neurochemical parameters, or processed for histological and immunohistochemical studies. Results showed that subchronic administration of ketamine was associated with a lesser weight gain inspite of an increase in food intake across the treatment groups. There was a dose-dependent increase in open-field novelty-induced behaviours, a decline in spatial working-memory, and an anxiolytic effect in the elevated-plus maze. There was associated derangement of serum triglyceride, and increase in brain glutamate levels, acetylcholinesterase activity, plasma/brain oxidative stress parameters, caspase-3 activity and biochemical indices of hepatic and renal function. Ketamine administration was also associated with neurodegenerative changes in the cerebral cortex, hippocampus, cerebellum and the pons. In conclusion, subchronic administration of ketamine to adolescent rats was associated with dose-related memory loss, oxidative stress and possibly caspase-3 mediated neurodegenerative changes.

Abstract
MoS2, a typical transition metal disulfide, is widely used in the photoelectrochemical (PEC) sensor construction. In general, MoS2 based PEC sensor are "signal-on" strategies. Surprisingly, we discovered that the PEC response of MoS2 was quenched by methionine greatly. Based on this discovery, a reduction PEC sensing strategy utilized MoS2 modified electrode for methionine detection was fabricated for the first time. Experimental factors, such as, bias potential, volume of MoS2 and pH were studied. Under optimized conditions, the decreased intensity of the photocurrent signal was proportional to the logarithmic value of methionine concentrations from 0.1 nM to 1 μM with the detection limit of 0.03 nM. Moreover, this method exhibited good performance of excellent selectivity. And it showed potential applications in the practical determination of methionine in real-life sample. This strategy not only expands the PEC detection method but also provides a simple, rapid response, good selectivity and high sensitivity way to detect methionine.

Abstract
BACKGROUND & OBJECTIVES Dengue fever, caused by dengue virus (DENV), has become a serious threat to human lives. Phytochemicals are known to have great potential to eradicate viral, bacterial and fungal-borne diseases in human beings. This study was aimed at in silico drug development against nonstructural protein 4B (NS4B) of dengue virus 4 (DENV4). METHODS A total of 2750 phytochemicals from different medicinal plants were selected for this study. These plants grow naturally in the climate of Pakistan and India and have been used for the treatment of various pathologies in human for long-time. The ADMET studies, molecular docking and density functional theory (DFT) based analysis were carried out to determine the potential inhibitory properties of these phytochemicals. RESULTS The ADMET analysis and docking results revealed nine phytochemicals, i.e. Silymarin, Flavobion, Derrisin, Isosilybin, Mundulinol, Silydianin, Isopomiferin, Narlumicine and Oxysanguinarine to have potential inhibitory properties against DENV and can be considered for additional in vitro and in vivo studies to assess their inhibitory effects against DENV replication. They exhibited binding affinity ≥ -8 kcal/mol against DENV4-NS4B. Furthermore, DFT based analysis revealed high reactivity for these nine phytochemicals in the binding pocket of DENV4-NS4B, based on ELUMO, EHOMO and band energy gap. INTERPRETATION & CONCLUSION Five out of nine phytochemicals are reported for the first time as novel DENV inhibitors. These included three phytochemicals from Silybum marianum, i.e. Derrisin, Mundulinol, Isopomiferin, and two phytochemicals from Fumaria indica, i.e. Narlumicine and Oxysanguinarine. However, all the nine phytochemicals can be considered for in vitro and in vivo analysis for the development of potential DENV inhibitors.

Abstract
Acetaminophen (APAP) overdose is the leading cause of drug-induced acute liver failure in many developed countries. Mitochondrial oxidative stress is considered to be the predominant cellular event in APAP-induced liver injury. Accordingly, N-acetyl cysteine, a known scavenger of reactive oxygen species (ROS), is recommended as an effective clinical antidote against APAP-induced acute liver injury (AILI) when it is given at an early phase; however, the narrow therapeutic window limits its use. Hence, the development of novel therapeutic approaches that can offer broadly protective effects against AILI is clearly needed. To this end, it is necessary to better understand the mechanisms of APAP hepatotoxicity. Up to now, in addition to mitochondrial oxidative stress, many other cellular processes, including phase I/phase II metabolism, endoplasmic reticulum stress, autophagy, sterile inflammation, microcirculatory dysfunction, and liver regeneration, have been identified to be involved in the pathogenesis of AILI, providing new targets for developing more effective therapeutic interventions against APAP-induced liver injury. In this review, we summarize intracellular and extracellular events involved in APAP hepatotoxicity, along with emphatic discussions on the possible therapeutic approaches targeting these different cellular events.
