Abstract
This study aims to explore the protective machinery of pegylated polymeric micelles of boswellic acid-selenium (PMBS) against secondary neuronal damage triggered by mild repetitive traumatic brain injury (RTBI). After PMBS characterization in terms of particle size, size distribution, zeta potential, and transmission electronic microscopy, the selected formula was used to investigate its potency against experimental RTBI. Five groups of rats were used; group 1 (control) and the other four groups were subjected to RTBI. Groups 2 was RTBI positive control, while 3, 4, and 5 received boswellic acid (BSA), selenium (SEL), and PMBS, respectively. The open-field behavioral test was used for behavioral assessment. Subsequently, brain tissues were utilized for hematoxylin and eosin staining, Nissl staining, Western blotting, and ELISA in addition to evaluating microRNA expression (miR-155 and miR-146a). The behavioral changes, oxidative stress, and neuroinflammation triggered by RTBI were all improved by PMBS. Moreover, PMBS mitigated excessive glutamate-induced excitotoxicity and the dysregulation in miR-155 and miR-146a expression. Besides, connexin43 (Cx43) expression as well as klotho and brain-derived neurotrophic factor (BDNF) were upregulated with diminished neuronal cell death and apoptosis because of reduced Forkhead Box class O3a(Foxo3a) expression in the PMBS-treated group. The current study has provided evidence of the benefits produced by incorporating BSA and SEL in PEGylated polymeric micelles formula. PMBS is a promising therapy for RTBI. Its beneficial effects are attributed to the manipulation of many pathways, including the regulation of miR-155 and miR-146a expression, as well as the BDNF /Klotho/Foxo3a signaling pathway.

Abstract
The prevalence of drug-resistant bacteria presents a significant challenge to the antibiotic treatment of Helicobacter pylori (H. pylori), while traditional antimicrobial agents often suffer from shortcomings such as poor gastric retention, inadequate alleviation of inflammation, and significant adverse effects on the gut microbiota. Here, a selenized chitosan (CS-Se) modified bismuth-based metal-organic framework (Bi-MOF@CS-Se) nanodrug is reported that can target mucin through the charge interaction of the outer CS-Se layer to achieve mucosal adhesion and gastric retention. Additionally, the Bi-MOF@CS-Se can respond to gastric acid and pepsin degradation, and the exposed Bi-MOF exhibits excellent antibacterial properties against standard H. pylori as well as clinical antibiotic-resistant strains. Remarkably, the Bi-MOF@CS-Se effectively alleviates inflammation and excessive oxidative stress by regulating the expression of inflammatory factors and the production of reactive oxygen species (ROS), thereby exerting therapeutic effects against H. pylori infection. Importantly, this Bi-MOF@CS-Se nanodrug does not affect the homeostasis of gut microbiota, providing a promising strategy for efficient and safe treatment of H. pylori infection.

Abstract
Peripheral nerve injury (PNI) seriously affects the health and life of patients, and is an urgent clinical problem that needs to be resolved. Nerve implants prepared from various biomaterials have played a positive role in PNI, but the effect should be further improved and thus new biomaterials is urgently needed. Ovalbumin (OVA) contains a variety of bioactive components, low immunogenicity, tolerance, antimicrobial activity, non-toxicity and biodegradability, and has the ability to promote wound healing, cell growth and antimicrobial properties. However, there are few studies on the application of OVA in neural tissue engineering. In this study, OVA implants with different spatial structures (membrane, fiber, and lyophilized scaffolds) were constructed by casting, electrospinning, and freeze-drying methods, respectively. The results showed that the OVA implants had excellent physicochemical properties and were biocompatible without significant toxicity, and can promote vascularization, show good histocompatibility, without excessive inflammatory response and immunogenicity. The in vitro results showed that OVA implants could promote the proliferation and migration of Schwann cells, while the in vivo results confirmed that OVA implants (the E5/70% and 20 kV 20 μL/min groups) could effectively regulate the growth of blood vessels, reduce the inflammatory response and promote the repair of subcutaneous nerve injury. Further on, the high-throughput sequencing results showed that the OVA implants up-regulated differential expression of genes related to biological processes such as tumor necrosis factor-α (TNF-α), phosphatidylinositide 3-kinases/protein kinase B (PI3K-Akt) signaling pathway, axon guidance, cellular adhesion junctions, and nerve regeneration in Schwann cells. The present study is expected to provide new design concepts and theoretical accumulation for the development of a new generation of nerve regeneration implantable biomaterials.

Abstract
The protective effect of selenium (Se) against Hg-induced neurotoxicity has been widely investigated; however, the mechanisms behind this interaction have not been fully elucidated yet. In the current work, the role of Se against MeHg+-induced cytotoxicity in the human neuroblastoma cell line (SH-SY5Y) is reported for the first time by tracking Hg uptake and accumulation at the single-cell level by inductively coupled plasma-mass spectrometry in single-cell mode (SC-ICP-MS). The influence of different Se species (SeMet, SeMeSeCys, citrate-SeNPs, and chitosan-SeNPs) on MeHg+ cytotoxicity was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays. SeMet and SeMeSeCys exhibited protective effects against MeHg+-induced cell death, particularly at high MeHg+ concentrations (LC50). In addition, chitosan-SeNPs showed greater protection compared to citrate-SeNPs when co-exposed with MeHg+. Interestingly, SC-ICP-MS unveiled the heterogeneous distribution of Hg uptake by SH-SY5Y cells. Co-exposure of SeMet and SeMeSeCys with MeHg+ led to a reduction of the amount of Hg accumulated per individual cell, which decreased the maximum level of Hg per cell by half (from 60 fg Hg cell-1 to 30 fg Hg cell-1) when SeMet was present, along with a decrease in the percentage of cells that accumulated the highest quantity of MeHg+. All these data corroborate the protective role of Se against Hg toxicity at the cellular level.

Abstract
Selenium compounds exert their antioxidant activity mostly when the selenium atom is incorporated into selenoproteins. In our work, we tested the possibility that selenite itself interacts with thiols to form active species that have reducing properties. Therefore, we studied the reduction of 2-(4-carboxyphenyl)-4,5-dihydro-4,4,5,5-tetramethyl-1H-imidazol-1-yloxy-3-oxide radical (•cPTIO), damage of plasmid DNA (pDNA), modulation of rat hemodynamic parameters and tension of isolated arteries induced by products of interaction of selenite with thiols. We found that the products of selenite interaction with thiols had significant reducing properties that could be attributed mainly to the selenide and that selenite had catalytic properties in the access of thiols. The potency of thiols to reduce •cPTIO in the interaction with selenite was cysteine > homocysteine > glutathione reduced > N-acetylcysteine. Thiol/selenite products cleaved pDNA, with superoxide dismutase enhancing these effects suggesting a positive involvement of superoxide anion in the process. The observed •cPTIO reduction and pDNA cleavage were significantly lower when selenomethionine was used instead of selenite. The products of glutathione/selenite interaction affected several hemodynamic parameters including rat blood pressure decrease. Notably, the products relaxed isolated mesenteric artery, which may explain the observed decrease in rat blood pressure. In conclusion, we found that the thiol/selenite interaction products exhibited significant reducing properties which can be used in further studies of the treatment of pathological conditions caused by oxidative stress. The results of decreased rat blood pressure and the tension of mesenteric artery may be perspective in studies focused on cardiovascular disease and their prevention.

Abstract
Imidacloprid (IMI) is a neonicotinoid insecticide with the highest global market share, and IMI exposure in the environment can negatively affect many nontarget organisms (a general term for organisms affected by drugs other than target organisms). Resveratrol (RSV), a non-flavonoid polyphenolic organic compound derived from peanuts, grapes, and other plants, has anti-inflammatory and antioxidant effects. It is currently unclear how RSV protects against cell damage caused by IMI. Therefore, we established an experimental model of chicken lymphocyte lines exposed to 110 μg/mL IMI and/or 0.5 μM RSV for 24 h. According to the experimental results, IMI markedly raised intracellular reactive oxygen species levels and diminished the activity of the cellular antioxidant enzymes (CAT, SOD, and GPx), leading to MDA accumulation and decreased T-AOC. JNK, ERK, and P38, the essential components of the mitogen-activated protein kinase (MAPK) signaling pathway, were also expressed more when IMI was present. Additionally, IMI resulted in upregulation of mitochondrial apoptosis (Caspase 3, Caspase 9, Bax, and Cyt-c) and necroptosis (Caspase 8, RIPK1, RIPK3, and MLKL) related factors expression, downregulation of Bcl-2 expression, induction of upregulation of cytokine IL-6 and TNF-α expression, and downregulation of IFN-γ expression. The combined treatment of RSV and IMI significantly reduced cellular oxidative stress levels, inhibited the MAPK signaling pathway, and alleviated IMI-induced mitochondrial apoptosis, necroptosis, and immune dysfunction. To summarize, RSV antagonized IMI-induced mitochondrial apoptosis, necroptosis, and immune dysfunction in chicken lymphocyte lines by inhibiting the ROS/MAPK signaling pathway.

Abstract
The aim of study was to evaluate the effect of selenium supplementation on disease activity, inflammation, and oxidative stress in patients with rheumatoid arthritis (RA). This study was a randomized double-blind placebo-controlled trial on 59 patients with RA. Participants were randomly divided to receive 200 μg/day of selenium or a placebo for 12 weeks. The disease activity score (DAS.CRP and DAS.ESR), erythrocyte sedimentation rate (ESR), serum levels of C-reactive protein (CRP), fasting blood glucose, lipids, antibodies to cyclic citrullinated protein (anti-CCP), nitric oxide, glutathione, and total antioxidant capacity were assessed. The mean of DAS.CRP and DAS.ESR decreased significantly within both study groups after the intervention. However, the between-group comparisons revealed no significant differences. The CRP levels decreased significantly in the selenium group, and this decrease was near the significance level compared to the placebo (P = 0.05). However, after adjusting for baseline values, the observed difference between groups did not remain significant. In addition, the values of ESR and anti-CCP decreased significantly within the selenium group. Although, between-group comparison did not statistically significant, the change in ESR and anti-CCP in the selenium group was small clinically relevant compared to the placebo [the effect size (95% CI) for ESR: 0.38 (- 0.14, 0.89), and for anti-CCP: 0.32 (- 0.2, 0.83)]. Our study showed that selenium caused a small clinically relevant improvement in some RA biomarkers such as ESR and anti-CCP. Future studies that evaluate the effects of novel forms of supplements such as selenium nanoparticles on the clinical symptoms and biomarkers of RA are suggested.

Free Radic Biol Med 2024; 212:49-64.

Abstract
Releasing unilateral ureteral obstruction (RUUO) is the gold standard for decreasing renal damage induced during unilateral ureteral obstruction (UUO); however, the complete recovery after RUUO depends on factors such as the time and severity of obstruction and kidney contralateral compensatory mechanisms. Interestingly, previous studies have shown that kidney damage markers such as oxidative stress, inflammation, and apoptosis are present and even increase after removal obstruction. To date, previous therapeutic strategies have been used to potentiate the recovery of renal function after RUUO; however, the mechanisms involving renal damage reduction are poorly described and sometimes focus on the recovery of renal functionality. Furthermore, using natural antioxidants has not been completely studied in the RUUO model. In this study, we selected sulforaphane (SFN) because it activates the nuclear factor erythroid 2-related factor 2 (Nrf2), a transcription factor that induces an antioxidant response, decreasing oxidative stress and inflammation, preventing apoptosis. Thus, we pre-administrated SFN on the second day after UUO until day five, where we released the obstruction on the three days after UUO. Then, we assessed oxidative stress, inflammation, and apoptosis markers. Interestingly, we found that SFN administration in the RUUO model activated Nrf2, inducing its translocation to the nucleus to activate its target proteins. Thus, the Nrf2 activation upregulated glutathione (GSH) content and the antioxidant enzymes catalase, glutathione peroxidase (GPx), and glutathione reductase (GR), which reduced the oxidative stress markers. Moreover, the improvement of antioxidant response by SFN restored S-glutathionylation in the mitochondrial fraction. Activated Nrf2 also reduced inflammation by lessening the nucleotide-binding domain-like receptor family pyrin domain containing 3 and interleukin 1β (IL-1β) production. Reducing oxidative stress and inflammation prevented apoptosis by avoiding caspase 3 cleavage and increasing B-cell lymphoma 2 (Bcl2) levels. Taken together, the obtained results in our study showed that the upregulation of Nrf2 by SFN decreases oxidative stress, preventing inflammation and apoptosis cell death during the release of UUO.

Hu Q, Qiu L, Ge L, Wei Y. Sevoflurane postconditioning alleviates hypoxic-ischemic brain damage in rats by inhibiting the endoplasmic reticulum stress PERK/ATF4/CHOP pathway. Tissue Cell 2024; 86:102289. [PMID: 38194851 DOI: 10.1016/j.tice.2023.102289] [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: 05/31/2023] [Revised: 12/07/2023] [Accepted: 12/08/2023] [Indexed: 01/11/2024]
Abstract
Hypoxic-ischemic brain damage (HIBD) frequently induces cognitive impairments. Investigating the role of sevoflurane postconditioning (SPC) in HIBD, we conducted experiments involving HIBD modeling, SPC treatment, and interventions with the PERK inhibitor GSK2656157 or the PERK activator CCT020312, administered 30 min before modeling, followed by SPC treatment. Behavioral testing using the Morris water maze test and Neurological Deficiency Scale (NDS) was conducted. Additionally, Nissl staining assessed hippocampal CA1 area neuronal density, TUNEL staining evaluated hippocampal CA1 area neuronal apoptosis, and Western blot determined hippocampal CA1 area protein levels, including Bax, Bcl-2, p-PERK/PERK, p-eIF2/eIF2, ATF4, CHOP, GRP78, Bax, and Bcl-2 protein levels. Following SPC treatment, HIBD rats exhibited improved spatial learning and memory abilities, reduced neuronal apoptosis, increased neuronal density in the hippocampal CA1 area, elevated Bcl-2 protein level, decreased Bax protein levels, and decreased levels of endoplasmic reticulum stress pathway related proteins (p-PERK/PERK, p-eIF2/eIF2, ATF4, CHOP and GRP78). Pre-modeling treatment with the PERK inhibitor treatment improved outcomes in HIBD rats. However, pre-modeling treatment with the PERK activator CCT020312 counteracted the protective effects of SPC against HIBD in rats. In conclusion, SPC alleviates neuronal apoptosis in the hippocampus CA1 area of HIBD rats by inhibiting the endoplasmic reticulum stress pathway PERK/ATF4/CHOP, thereby mitigating HIBD in rats.

Selenium alleviates modafinil-induced neurobehavioral toxicity in rat via PI3K/Akt/mTOR/GSK3B signaling pathway and suppression of oxidative stress and apoptosis: in vivo and in silico study. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2024; 31:458-480.

Abstract
Nonmedical use of modafinil (MOD) led to increased rates of overdose toxicity, road accidents, addiction, withdrawal, suicide, and mental illnesses. The current study aims to determine the probable MOD brain toxicity and elucidate the possible role of selenium (Se) in ameliorating the neurotoxicity in rat models. Fifty-four male Albino rats were randomly assigned into nine groups. The groups were G1 (control negative), G2 (Se0.1), G3 (Se0.2), G4 (MOD300), G5 (MOD600), G6 (Se0.1 + MOD300), G7 (Se0.2 + MOD300), G8 (Se0.1 + MOD600), and G9 (Se0.2 + MOD600). After finishing the experiment, blood and brain tissue were harvested for biochemical and histological investigation. Neurobehavior parameters were assessed. Tissue neurotransmitter levels and oxidative stress markers were assessed. Gene expression of PI3K/Akt/mTOR-GSK3B, orexin, and orexin receptor2 was measured by qRT-PCR. Histological and immunohistochemistry assessments, as well as molecular docking, were carried out. MOD-induced neurobehavioral toxicity exhibited by behavioral and cognitive function impairments, which are associated with decreased antioxidant activities, increased MDA levels, and decreases in neurotransmitter levels. Brain levels of mRNA expression of PI3K, Akt, and mTOR were decreased, while GS3K, orexin, and orexin receptors were significantly elevated. These disturbances were confirmed by histopathological brain changes with increased silver and Bax immunostaining and decreased crystal violet levels. MOD induced neurotoxic effects in a dose-dependent manner. Compared with the MOD groups, SE coadministration significantly attenuates MOD-induced toxic changes. Docking study shows the protective role of Se as an apoptosis inhibitor and inflammation inhibitor. In conclusion, Se could be used as a biologically effective antioxidant compound to protect from MOD neurobehavioral toxicity in Wistar rats by reversing behavioral alterations, inflammation, apoptosis, and oxidative injury.

Abstract
Mercuric chloride (HgCl2) is a heavy metal that is toxic to the human body. Carvacrol (CAR) is a flavonoid found naturally in plants and has many biological and pharmacological activities including anti-inflammatory, antioxidant, and anticancer activities. This study aimed to investigate the efficacy of CAR in HgCl2-induced testicular tissue damage. HgCl2 was administered intraperitoneally at a dose of 1.23 mg/kg body weight alone or in combination with orally administered CAR (25 mg/kg and 50 mg/kg body weight) for 7 days. Biochemical and histological methods were used to investigate oxidative stress, inflammation, apoptosis, and autophagy pathways in testicular tissue. CAR treatment increased HgCl2-induced decreased antioxidant enzyme (SOD, CAT, and GPx) activities and GSH levels. In addition, CAR reduced MDA levels, a marker of lipid peroxidation. CAR decreased the levels of inflammatory mediators NF-κB, TNF-α, IL-1β, COX-2, iNOS, MAPK14, MAPK15, and JNK. The increases in apoptotic Bax and Caspase-3 with HgCl2 exposure decreased with CAR, while the decreased antiapoptotic Bcl-2 level increased. CAR reduced HgCl2-induced autophagy damage by increasing Beclin-1, LC3A, and LC3B levels. Overall, the data from this study suggested that testicular tissue damage associated with HgCl2 toxicity can be mitigated by CAR administration.

Abstract
BACKGROUND Heavy metals are one of the environmental pollutants. Lead (Pb) is one of the most common of these heavy metals. In this study, it was aimed at investigating the effects of syringic acid (SA) against testicular toxicity in rats administered lead acetate (PbAc). METHODS In the present study, a total of 35 Sprague-Dawley rats, 7 in each group, were used. The rats were divided into 5 groups, with 7 male rats in each group. Rats were given PbAc and SA orally for 7 days. The effects of PbAc and SA on epididymal sperm quality and apoptosis, inflammation, oxidative stress and histopathological changes in testicular tissue were determined. RESULTS While PbAc disrupted the seminiferous tubules and produced atrophic images, SA corrected these histological abnormalities. PbAc adminisration significantly reduced the levels of SOD, GSH, GPx, CAT, NRF-2 and NQO1 and significantly increased the levels of MDA and 8-OHdG in the testicular tissue of rats, while SA improved this situation. NF-κB, TNF-α, IL-1β, NLRP3, RAGE, ATF6, PERK, IRE1, CHOP, and GRP78 genes expression levels increased with PbAc administration, however these levels decreased with SA administration. In addition, PbAc increased the levels of apoptotic markers Bax, Caspase-3 and APAF-1 and decreased the level of Bcl-2, while SA improved this situation. It was observed that PbAc significantly reduced sperm quality in rats, while SA positively affected sperm quality. CONCLUSION As a result, SA administered against PbAc-induced testicular dysfunction in rats can provide effective protection at doses of 25 mg/kg/bw and 50 mg/kg/bw.

Abstract
Chlorpyrifos (CPF), a widely used organophosphate pesticide that has caused large-scale contamination globally, has become a major concern. Baicalein (BAI), as a flavonoid extract, shows anti-inflammatory as well as antioxidant activities. The kidneys of fish serve to excrete toxins and are major target organs for environmental contaminants. However, it is not obvious whether BAI can counteract the damage caused by CPF exposure to fish kidneys. Therefore, we conducted a 30-day simulation of CPF poisoning and/or BAI treatment by adding 23.2 μg/L CPF to water and/or 0.15 g/kg BAI to feed. In the transmission electron microscopy results, we observed obvious phenomenon of autophagy and apoptosis in the CPF group, and the TUNEL staining and immunofluorescence of LC3B and p62 double-staining results confirmed that CPF induced autophagy and apoptosis in the kidney of common carp. Furthermore, CPF induced the increase of ROS level and inhibition of PI3K and Nrf2 pathways, which in turn triggered oxidative stress, autophagy and apoptosis in carp kidney according to western blot, RT-qPCR and kit assays. However, addition of BAI significantly alleviated oxidative stress, autophagy and apoptosis due to binding to PI3K protein. Additionally, through phylogenetic tree and structural domain analyses, we also found that the binding sites of BAI and PI3K are conserved in a variety of representative species. These results suggest that BAI antagonizes CPF-caused renal impairments in carp involving the PI3K/AKT pathway and the Nrf2 pathway. Our findings provide new insights into the nephrotoxicity effects of CPF and the potential use of BAI as a detoxification agent for CPF intoxication.

Abstract
Exposure to cadmium has been related to liver and kidney diseases such as polycystic and nephrotic syndrome. It is still unclear how cadmium contributes to these diseases. It is believed that the induction of oxidative stress resulting from the inhibition of antioxidant enzyme activities and changes in drug-metabolizing enzymes in the liver could explain the role of cadmium in the development of different diseases in the kidney and probably other organs. Changes in oxidative stress markers, antioxidant enzymes, and drug-metabolizing enzyme activities were assessed in the liver of male rats exposed to cadmium chloride. Additionally, the protective effects of silymarin and garlic extract against cadmium toxicosis were evaluated. Rats were randomly divided into eight groups as follows, groups 1, 2, 3, 4, and 5, received orally saline, CdCl2 (1 mg/kg), garlic extract [800 mg/kg], silymarin (25 mg/kg) and silymarin plus garlic extract respectively for 28 consecutive days. Rats in groups 6, 7, and 8 were pretreated with the same doses of garlic, silymarin, and garlic plus silymarin, respectively for two hours before cadmium administration. The Western immunoblotting technique was used to investigate the protein expression of cytochrome P450 isozymes. Spectrophotometric methods were used to assess the activity of both antioxidant- and drug-metabolizing enzymes. Free radical levels [measured as thiobarbituric acid reactive substances (TBARS)], catalase, superoxide dismutase, and glutathione peroxidase activities increased whereas the levels of glutathione and the activities of glutathione S-transferase, glutathione reductase, and glutamyl transferase, cytochrome P450, aryl hydrocarbon dehydrogenase (AHH), dimethylnitrosamine-N-demethylase I (DMN-dI), 7-ethoxycoumarine-O-deethylase (ECOD), cytochrome b5 and NADPH-Cytochrome-c-reductase enzyme activities decreased after cadmium treatment. Furthermore, Western immunoblotting data revealed that glutathione peroxidase protein expression increased following cadmium exposure, but cytochrome P450 2E1 and 3A4 expressions were downregulated. However, pretreatment of rats with silymarin or garlic extract or both before cadmium administration was found to restore the protein expression of cytochrome P450 2E1 and 3A4, the level of free radicals, antioxidant enzymes, drug-metabolizing enzyme activities to their normal levels. Similarly, histological studies revealed that silymarin and/or garlic extract reduced the liver damage caused by cadmium. Silymarin and/or garlic extract reduced the adverse effects of cadmium on the activity of both drug-metabolizing and antioxidant enzymes activity. These antioxidants could be provided to those who work in cadmium-based sectors to help them cope with the adverse effects of cadmium on their kidneys. In addition, Inhibiting drug-metabolizing enzyme activity should be considered when administering therapeutic medications to persons exposed to cadmium because most therapeutic drugs and many endogenous substances are largely metabolized by these enzymes.

Abstract
Cypermethrin (CYP, IUPAC name: [cyano-(3-phenoxyphenyl)methyl] 3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropane-1-carboxylate) is a pyrethroid insecticide that poses a threat to the health of humans and aquatic animals due to its widespread use and environmental contamination. However, the mechanism of CYP on apoptosis, autophagy and inflammation in hepatocytes of carp (Cyprinus carpio) is unknown. We hypothesized that CYP caused damage to hepatocytes through the endoplasmic reticulum stress (ERS) pathway, CCK-8 was used to detect the toxic effects of different doses of CYP on hepatocytes, and finally low (L, 10 μM), medium (M, 40 μM), and high (H, 80 μM) doses of CYP was selected to construct the model. ROS staining, oxidative stress-related indices (MDA, CAT, T-AOC, SOD), AO/EB staining, MDC staining, and the expression levels of related genes were detected using qRT-PCR and western blot. Our results showed that CYP exposure resulted in an increase in ROS production, an increase in MDA content, and a decrease in the activity of CAT, SOD, and T-AOC in hepatocytes; the proportion of apoptotic, necrotic, and autophagic cells increased significantly in a dose-dependent manner. We also found that CYP exposure increased the expression levels of endoplasmic reticulum-related genes (GRP78, PERK, IRE-1, ATF-6 and CHOP), apoptosis (Bcl-2, Bax, Caspase-3, Caspase-9 and Cyt-c) and autophagy-related genes (LC3b, Beclin1 and P62) also showed dose-dependent changes, and the expression levels of inflammation-related genes (NF-κB, TNF-α, IL-1β, IL-6) were also significantly elevated. Thus, we demonstrated that CYP exposure caused apoptosis, autophagy and inflammation in hepatocytes via ERS-ROS-NF-κB axis. This research contributes to our understanding of the molecular mechanisms underlying CYP-induced damage in hepatocytes of carp (Cyprinus carpio).

Abstract
The micronutrient selenium (Se) has been shown to exert potential anticancer properties. This study aimed to evaluate the effects of Se (in Se yeast form) on the selenoproteins (SELENO), AR/IGF-1R/EGFR, PI3K/Akt/mTOR and Ras/Raf/ERK cascades, and immune checkpoint blockade in TNBC murine 4T1 cells. We also assessed the effects of combination treatment with chemotherapeutic doxorubicin and Se on trophoblast cell surface antigen 2 (TROP2) levels. Compared with the control groups, cells incubated with Se (0.25, 0.5, 0.75, 1.0, 1.5 µg Se/mL) have lower viability, raised intracellular Se concentrations and SELENO expression, and higher malondialdehyde products in a dose-dependent manner. Se induced the inactivation of AR/IGF-1R/EGFR and downregulation of the PI3K/Akt/mTOR and Ras/Raf/ERK signaling molecules. Se-treated cells also exhibited decreased mitochondrial membrane potential, reduced levels of the cell cycle regulatory protein cyclin D1, cancer stemness, metastatic and EMT-related markers, and increased apoptosis. Subsequently, Se treatment significantly suppressed PD-1/PD-L1 and CTLA-4 mRNA levels and proteins. Doxorubicin decreased 4T1 cell viability and TROP2 expression levels, but the addition of Se to doxorubicin contributed to further reductions. Similar responses to Se treatment were also observed in the human MDA-MB-231 and MCF-7 breast cancer cells. These results show that Se upregulates SELENO and anti-AR/IGF-1R/EGFR signaling in TNBC cells, thus inducing oxidative stress-dependent apoptosis and cell cycle arrest, stemness, EMT, and metastasis, as well as blocking the immune checkpoint molecules. TROP2 down-regulation with Se is also a potential anti-TNBC therapeutic target.

[PMID: 37661035 DOI: 10.1016/j.fsi.2023.109046] [Citation(s) in RCA: 13] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Revised: 08/28/2023] [Accepted: 08/31/2023] [Indexed: 09/05/2023]
Abstract
Lambda-cyhalothrin (LC), a pyrethroid insecticide widely used in agriculture, causes immunotoxicity to aquatic organisms in the aquatic environment. Microalgal astaxanthin (MA) is a natural carotenoid that enhances viability of a variety of fish. To investigate the immunotoxicity of LC and the improvement effect of MA in lymphocytes (Cyprinus carpio), lymphocytes were treated with LC (80 M) and/or MA (50 M) for 24 h. Firstly, CCK8 combined with PI staining results showed that MA significantly attenuated the LC-induced lymphocyte death rate. Secondly, LC exposure resulted in excessively damaged mitochondrial and mtROS, diminished mitochondrial membrane potential and ATP content, which could be improved by MA. Thirdly, MA upregulated the levels of mitophagy-related regulatory factors (Beclin1, LC3, ATG5, Tom20 and Lamp2) induced by LC. Importantly, MA decreased the levels of pyroptosis-related genes treated with LC, including NLRP3, Cas-4, GSDMD and active Cas-1. Further study indicated that LC treatment caused excessive miRNA-194-5p and reduced levels of FoxO1, PINK1 and Parkin, which was inhibited by MA treatment. Overall, we concluded that MA could enhance damaged mitochondrial elimination by promoting the miRNA-194-5p-FoxO1-PINK1/Parkin-mitophagy in lymphocytes, which reduced mtROS accumulation and alleviated pyroptosis. It offers insights into the importance of MA application in aquaculture as well as the defense of farmed fish against agrobiological hazards in fish under LC.

Molecular Mechanisms of Selenium Mitigating Lead Toxicity in Chickens via Mitochondrial Pathway: Selenoproteins, Oxidative Stress, HSPs, and Apoptosis. TOXICS 2023; 11:734. [PMID: 37755744 PMCID: PMC10536545 DOI: 10.3390/toxics11090734] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Revised: 08/19/2023] [Accepted: 08/24/2023] [Indexed: 09/28/2023]
Abstract
Lead (Pb), a hazardous heavy metal, can damage the health of organisms. However, it is not clear whether Pb can damage chicken cerebellums and thalami. Selenium (Se), an essential nutrient for organisms, has a palliative effect on Pb poisoning in chickens. In our experiment, a model of chickens treated with Pb and Se alone and in combination was established to investigate the molecular mechanism of Se alleviating Pb-caused damage in both chicken cerebellums and thalami. Our morphological results indicated that Pb caused apoptotic lesions, such as mitochondrial and nuclear damage. Further, the anti-apoptotic gene Bcl-2 decreased; on the contrary, four pro-apoptotic genes (p53, Bax, Cyt c, and Caspase-3) increased under Pb treatment, meaning that Pb caused apoptosis via the p53-Cyt c-Caspase-3 pathway. Furthermore, we further demonstrated that Pb elevated four HSPs (HSP27, HSP40, HSP70, and HSP90), as well as HSP70 took part in the molecular mechanism of Pb-caused apoptosis. In addition, we found that Pb exposure led to oxidative stress via up-regulating the oxidant H2O2 and down-regulating four antioxidants (CAT, SOD, GST, and GPx). Moreover, Pb decreased three Se-containing factors (Txnrd1, Txnrd2, and Txnrd3), further confirming that Pb caused oxidative stress. Interestingly, Se supplementation reversed the above changes caused by Pb and alleviated Pb-induced oxidative stress and apoptosis. A time dependency was demonstrated for Bcl-2, Bax, and Cyt c in the cerebellums, as well as CAT, GPx, and p53 in the thalami of Pb-exposed chickens. HSP70 in cerebellums and HSP27 in thalami were more sensitive than those in thalami and cerebellums, respectively, under Pb exposure. Pb-induced apoptosis of thalami was more severe than cerebellums. In conclusion, after Pb treatment, Txnrds mediated oxidative stress, oxidative stress up-regulated HSPs, and finally, HSP70 triggered apoptosis. Se supplementation antagonized Pb-induced oxidative stress and apoptosis via the mitochondrial pathway and selenoproteins in chicken cerebellums and thalami. This study provides new information for the mechanism of environmental pollutant poisoning and the detoxification of Se on abiotic stress.

Abstract
BACKGROUND Neurodegenerative diseases (NDs) have posed significant challenges to public health, and it is crucial to understand their mechanisms in order to develop effective therapeutic strategies. Recent studies have highlighted the potential role of selenium in ND pathogenesis, as it plays a vital role in maintaining cellular homeostasis and preventing oxidative damage. However, a comprehensive analysis of the association between selenium and NDs is still lacking. METHOD Five public databases, namely PubMed, Web of Science, EMBASE, Cochrane and Clinical Trials, were searched in our research. Random model effects were chosen, and Higgins inconsistency analyses (I2), Cochrane's Q test and Tau2 were calculated to evaluate the heterogeneity. RESULT The association of selenium in ND patients with Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS) and Huntington's disease (HD) was studied. A statistically significant relationship was only found for AD patients (SMD = -0.41, 95% CI (-0.64, -0.17), p < 0.001), especially for erythrocytes. However, no significant relationship was observed in the analysis of the other four diseases. CONCLUSION Generally, this meta-analysis indicated that AD patients are strongly associated with lower selenium concentrations compared with healthy people, which may provide a clinical reference in the future. However, more studies are urgently needed for further study and treatment of neurodegenerative diseases.

Areca catechu L. ameliorates chronic unpredictable mild stress-induced depression behavior in rats by the promotion of the BDNF signaling pathway. Biomed Pharmacother 2023; 164:114459. [PMID: 37245336 DOI: 10.1016/j.biopha.2023.114459] [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: 12/16/2022] [Revised: 02/23/2023] [Accepted: 02/26/2023] [Indexed: 05/30/2023] Open
Abstract
OBJECTIVES In this study, we have investigated the anti-depressant effects of the fruit Areca catechu L. (ACL) and elucidated its potential underlying mechanism using a rat model of chronic unpredictable mild stress (CUMS). METHODS CUMS was induced in rats to establish a depression animal model for 28 days. According to the baseline sucrose preference, the male rats were divided into 6 different groups. They were treated with paroxetine hydrochloride, ACL, and water once a day until the behavioral tests were performed. The levels of corticosterone (CORT), malondialdehyde (MDA), catalase (CAT), and total superoxide dismutase (T-SOD) in serum were detected using a commercial kit, and the concentrations of 5-hydroxytryptamine (5-HT) and dopamine (DA) monoamine neurotransmitters in the brain tissues were detected by liquid chromatography-tandem mass spectrometry. doublecortin (DCX) expression in the hippocampal dentate gyrus (DG) was determined by immunofluorescence, and the relative abundance of brain-derived neurotrophic factor (BDNF), TrkB, PI3K, p-AKT/AKT, PSD-95, and p-GSK-3β/GSK-3β of brain tissues were assayed by western blot. RESULTS ACL markedly increased sucrose preference, decreased the immobility time, and shortened the feeding latency of CUMS-induced rats. CUMS induction resulted in marked changes in the contents of the monoamine neurotransmitters (5-HT and DA) in the hippocampus and cortex of brain tissues and the levels of CORT, MDA, CAT, and T-SOD in serum, whereas ACL administration alleviated these considerable changes. ACL promoted DCX expression in DG and increased the protein levels of BDNF, TrkB, PI3K, p-AKT/AKT, PSD-95, and p-GSK-3β/GSK-3β in the brains of CUMS-induced rats. CONCLUSIONS Our results indicated that ACL may improve depression-like behaviors in CUMS-induced rats by decreasing the hyperfunction and oxidative stress of the hypothalamic-pituitary-adrenal axis, stimulating hippocampal neurogenesis, and activating the BDNF signaling pathway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Huangqi baihe Granules (HQBHG), which is a key Chinese medical prescription, has a remarkable efficacy in oxidative stress and inflammation. Nevertheless, the therapeutic effect on Radiation brain injury (RBI) has rarely been studied. AIM OF THE STUDY The study aimed to verify the effect of HQBHG against RBI and explore its potential mechanism. METHODS The potential targets and mechanisms of HQBHG against RBI were predicted by network pharmacology and verified by established rat model of RBI Firstly, the therapeutic effect of HQBHG in RBI was confirmed by water maze test, HE staining and Enzyme-linked immunosorbent assay (ELISA). Secondly, the potential critical anti-RBI pathway of HQBHG was further explored by water maze, HE staining, immunofluorescence assays, ELISA and western blot. RESULTS A total of 43 HQBHG anti-RBI targets were obtained. Gene Ontology (Go) and Kyoto Encyclopedia of Genes and Genomes (KEGG) functional annotations showed that the treatment of HQBHG in RBI might be mainly related to oxidative stress, inflammation and PI3K/AKT pathway. Experimental studies have indicated that HQBHG can improve spatial learning and memory ability, alleviate pathological damage of brain tissue in RBI of rats. HQBHG also can down-regulate the levels of IL-1β, TNF-α, ROS and MDA, meanwhile, GSH was significantly up-regulated. In addition, the HQBHG can increase the protein expression phosphorylations PI3K (p-PI3K), phosphorylations AKT(p-AKT) and Nrf2 in the brain tissue of RBI. CONCLUSION HQBHG may alleviated RBI by regulated oxidative stress and inflammatory response through PI3K/AKT/Nrf2 pathway.

Abstract
Mercury is a highly toxic heavy metal with definite cardiotoxic properties and can affect the health of humans and animals through diet. Selenium (Se) is a heart-healthy trace element and dietary Se has the potential to attenuate heavy metal-induced myocardial damage in humans and animals. This study was designed to explore antagonistic effect of Se on the cardiotoxicity of mercuric chloride (HgCl2) in chickens. Hyline brown hens received a normal diet, a diet containing 250 mg/L HgCl2, or a diet containing 250 mg/L HgCl2 and 10 mg/kg Na2SeO3 for 7 weeks, respectively. Histopathological observations demonstrated that Se attenuated HgCl2-induced myocardial injury, which was further confirmed by the results of serum creatine kinase and lactate dehydrogenase levels assay and myocardial tissues oxidative stress indexes assessment. The results showed that Se prevented HgCl2-induced cytoplasmic calcium ion (Ca2+) overload and endoplasmic reticulum (ER) Ca2+ depletion mediated by Ca2+-regulatory dysfunction of ER. Importantly, ER Ca2+ depletion led to unfolded protein response and endoplasmic reticulum stress (ERS), resulting in apoptosis of cardiomyocytes via PERK/ATF4/CHOP pathway. In addition, heat shock protein expression was activated by HgCl2 through these stress responses, which was reversed by Se. Moreover, Se supplementation partially eliminated the effects of HgCl2 on the expression of several ER-settled selenoproteins, including selenoprotein K (SELENOK), SELENOM, SELENON, and SELENOS. In conclusion, these results suggested that Se alleviated ER Ca2+ depletion and oxidative stress-induced ERS-dependent apoptosis in chicken myocardium after HgCl2 exposure.

Abstract
Selenium deficiency can lead to multiple tissue and organ damage in the body and could coexist with chronic toxic exposures. Contamination from Bisphenol A (BPA) exposure can induce the occurrence of various injuries including pyroptosis. However, it is not clear whether selenium deficiency and BPA exposure affect tracheal tissue pyroptosis in chickens. To investigate whether selenium deficiency and BPA exposure induce chicken tracheal tissue pyroptosis via the NF-κB/NLRP3/Caspase-1 pathway and the effect of their combined exposure on tissue injury, we developed a model of relevant chicken tracheal injury. Sixty broilers were divided into four groups: the control group (C group), selenium-deficient group (SeD group), BPA-exposed group (BPA group) and combined exposure group (SeD + BPA group). The study examined the expression indicators of markers of pyroptosis (NLRP3&GSDMD), NF-κB pathway-related inflammatory factors (NF-κB, iNOS, TNF-α, COX-2), pyroptosis-related factors (ASC, Caspase-1, IL-1β, IL-18), and some heat shock proteins and interleukins (HSP60, HSP90, IL-6, IL-17) in the samples. The results showed that the expression of the above indicators was significantly upregulated in the different treatment groups (P < 0.05). In addition, the expression levels of the above related indicators were more significantly up-regulated in the combined selenium-deficient and BPA-exposed group compared to the group in which they were individually exposed. It was concluded that selenium deficiency and BPA exposure induced tracheal tissue pyroptosis in chickens through NF-κB/NLRP3/Caspase-1 pathway, and BPA exposure exacerbated selenium deficiency-induced tracheal pyroptosis. The present study provides new ideas into studies related to the co-exposure of organismal micronutrient deficiency and chronic toxicants.

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2022; 248:114307. [PMID: 36423370 DOI: 10.1016/j.ecoenv.2022.114307] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 11/12/2022] [Accepted: 11/15/2022] [Indexed: 06/16/2023]
Abstract
Lead (Pb), as a deleterious heavy metal, ubiquitously exists in environment and industry, which engenders multi-organ disfunction, especially the brain of infants who are vulnerable to attack from lead-induced neurotoxicity. Although cholesterol sulfate (CS) is crucial constituent of cell membranes and precursor of neurosteroids, which maintains the function and survival of neurons, the role of CS in lead-induced neurological damage still remains incomplete. In this work, Rat Brain Astrocytes cell line (CTX cells) was applied into exploration that protective effects of CS on CTX cell apoptosis induced by lead via the regulation of BDNF/TrkB signaling pathway mediated cholesterol metabolism. We found that CTX cells exposed to lead manifested apparent cytotoxicity, where the viability of CTX cells was significantly suppressed, accompanied with the elevation of apoptosis, in response to a trend towards increases in reactive oxygen species (ROS) production and pro-apoptotic protein Cleaved-caspase3, synchronized with the decline in anti-apoptotic protein Bcl-2. Moreover, accumulation of lead in CTX cells showed a dose-dependent increase, and meanwhile, decrements in cholesterol content occurred along with increase in lead exposure, in which expressions of cholesterol metabolism related proteins and transcriptions of its genes (SREBP2, LDLR, and HMGCR) were diminished. Furthermore, BDNF signaling pathway was obviously blocked after lead exposure, down-regulating expressions of proteins BDNF and TrkB. However, pretreatment with CS detoxified the negative impacts of lead-invoked CTX cell damage, acting as an effective remedy for apoptosis, imbalance of cholesterol metabolism and inhibition of BDNF signaling pathway. In addition, the relationship between BDNF signaling pathway and cholesterol metabolism was further verified, in which cholesterol metabolism related proteins and genes were promoted significantly after the activation of BDNF/TrkB signaling pathway using 7,8-Dihydroxyflavone (7,8-DHF), thereby detoxifying lead-induced CTX cell injury. However, the pretreatment of TrkB inhibitor ANA-12 offset the promotion of 7,8-DHF and ultimately inhibit cholesterol metabolism. Overall, our study demonstrated that CS could initiate the BDNF/TrkB signaling pathway, regulating the cholesterol metabolism against CTX cell apoptosis invoked by lead.

Shalan MG. Amelioration of mercuric chloride-induced physiologic and histopathologic alterations in rats using vitamin E and zinc chloride supplement. Heliyon 2022; 8:e12036. [PMID: 36544834 PMCID: PMC9761730 DOI: 10.1016/j.heliyon.2022.e12036] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Revised: 09/26/2022] [Accepted: 11/24/2022] [Indexed: 12/11/2022] Open
Abstract
The drastic effects of mercuric chloride and the protective efficiency of vitamin E and zinc chloride co-supplementation were clearly investigated in this study. Male rats were divided into four groups. The first was the control. The second received vitamin E (100 mg/kg) and zinc chloride (30 mg/kg) daily. In comparison, the third received mercuric chloride (1 mg/kg) daily, and the fourth received the same mercuric chloride dose supplemented with the same vitamin E and zinc chloride doses. Mercury promotes a significant decline in body weight. It causes a considerable reduction in total red blood cells (RBCs) count and hemoglobin concentration; however, white blood cells (WBCs) increased significantly. Significant mercury-induced elevations in hepatic and renal functions were observed. Mercury induced substantial reductions in catalase (CAT) and superoxide dismutase (SOD). Mercury caused apoptotic DNA fragmentation. It induced degeneration and necrosis in the liver and kidney. It induced necrosis, leukocyte infiltration and blood vessel congestion in the cerebral cortex. Shrinkage and deterioration of Purkinje cells of the cerebellum were observed in response to mercuric chloride toxicity. Mercuric chloride enhanced shrinking in seminiferous tubules and Leydig cells. It reduced sperm count, sperm motility, and testosterone concentration; however, it promoted abnormal sperm morphology. Administration of vitamin E and zinc chloride showed marked improvement in different parameters under investigation, however, further research is needed to determine fate of mercury.

Int J Nanomedicine 2022; 17:4807-4827. [PMID: 36246933 PMCID: PMC9562773 DOI: 10.2147/ijn.s374024] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Accepted: 09/21/2022] [Indexed: 11/05/2022] Open
Abstract
Purpose The bidirectional communication between the gut and the central nervous system mediated by gut microbiota is closely related to the occurrence and development of neurodegenerative diseases, including Alzheimer's disease (AD). Selenium (Se) has been identified as playing a role against AD. Probiotics have beneficial effects on host brain function and behavior by modulating the microbiota-gut-brain axis. Herein, we evaluated the protective effects of Lactobacillus casei ATCC 393 (L. casei ATCC 393) and selenium nanoparticles-enriched L. casei ATCC 393 (L. casei ATCC 393-SeNPs) against D-galactose/aluminum chloride-induced AD model mice. Methods The Morris Water Maze (MWM) test was used to assess cognitive function of mice. The morphology and histopathological changes, antioxidant capacity and immune responses in the brain and ileum were evaluated. The alterations in intestinal permeability of the mice were determined using FITC-dextran. Gut microbiota composition was assessed using 16s rRNA sequencing. Results Thirteen weeks intervention with L. casei ATCC 393 or L. casei ATCC 393-SeNPs significantly improved cognitive dysfunction, and minimized amyloid beta (Aβ) aggregation, hyperphosphorylation of TAU protein, and prevented neuronal death by modulating Akt/cAMP-response element binding protein (CREB)/brain-derived neurotrophic factor (BDNF) signaling pathway. Moreover, compared with L. casei ATCC 393, L. casei ATCC 393-SeNPs further effectively mitigated intestinal barrier dysfunction by improving antioxidant capacity, regulating immune response, restoring gut microbiota balance, and increasing the level of short-chain fatty acids and neurotransmitters, thereby inhibiting the activation of microglia and protecting brain neurons from neurotoxicity such as oxidative stress and neuroinflammation. Conclusion These findings indicated that targeting the microbiota-gut-brain axis with L. casei ATCC 393-SeNPs may have therapeutic potential for the deficits of cognitive function in the AD model mice. Thus, we anticipate that L. casei ATCC 393-SeNPs may be a promising and safe Se nutritional supplement for use as a food additive to prevent the neurodegenerative disease.

FISH & SHELLFISH IMMUNOLOGY 2022; 128:684-694. [PMID: 36028057 DOI: 10.1016/j.fsi.2022.08.053] [Citation(s) in RCA: 43] [Impact Index Per Article: 21.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Revised: 08/19/2022] [Accepted: 08/20/2022] [Indexed: 06/15/2023]
Abstract
Acetochlor is a high-volume herbicide whose widespread use threatens ecosystems and affects aquaculture. Apoptosis and autophagy are important causes of hepatotoxicity caused by toxicants, which can be mediated by oxidative stress and the inhibition of PPAR/RXR pathway. However, the mechanism of acetochlor on fish hepatocyte damage still needs to be further investigated. Therefore, we treated the Ctenopharyngodon idella hepatic cell line (L8824 cells) with different concentrations (10, 20, and 40 μM) of acetochlor and/or ROS scavenger NAC (1 mM) for 24 h. The results showed that acetochlor decreased the cell viability in a dose-dependent manner. AO/EB staining and flow cytometry verified the increased apoptotic rates. Quantitative analysis of gene expression levels or protein expression levels displayed that the expression levels of Beclin1, P62, LC3B, BAX, and cleaved Casp3 were increased, and the expression of BCL2 was reduced. Besides, we detected the increased ROS contents and decreased PPAR/RXR pathway expressions after acetochlor treatment. The clearance of ROS alleviated the inhibition of the PPAR/RXR pathway and lightened apoptosis and autophagy under acetochlor stress. Overall, these results revealed that acetochlor exposure triggered BCL2/BAX/Casp3-cascaded apoptosis and Beclin1-dependent autophagy through ROS-mediated PPAR/RXR inhibition. The results partially explain the toxicological mechanism of acetochlor and provide targets for the development of its antidote.

The decrease of selenoprotein K induced by selenium deficiency in diet improves apoptosis and cell progression block in chicken liver via the PTEN/PI3K/AKT pathway. Free Radic Biol Med 2022; 189:20-31. [PMID: 35841984 DOI: 10.1016/j.freeradbiomed.2022.07.005] [Citation(s) in RCA: 32] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Revised: 07/09/2022] [Accepted: 07/11/2022] [Indexed: 01/05/2023]
Abstract
Selenoprotein K (SELK) is imperative for normal development of chicken. It does regulate to chicken's physiological function. However, the injury of SELK-deficiency done on chicken liver and its underlying mechanism involved has not yet been covered. Therefore, we built SELK- deficiency model by feeding diet which contained low concentration of selenium (Se) to discuss SELK's regulation mechanism. Through using TUNEL, TEM, western blot and qRT-PCR we found apoptosis occurred in chicken liver in the SELK-deficiency groups. In the meanwhile, our study showed there were differentially expressed of the PTEN/PI3K/AKT pathway, calcium homeostasis, endoplasmic reticulum healthy and cell cycle progression in SELK-deficiency chicken liver tissues. In order to claim the regulation mechanism of SELK, we set SELK-knock down model in the LMH. The results in vitro were coincided with those in vivo. In the SELK-deficiency groups, the PTEN/PI3K/AKT pathway was activated and then induced ERS which eventually resulted in apoptosis in chicken liver. As the same time, the PTEN/PI3K/AKT pathway also regulated the combined effective of MDM2-p53, which leaned liver cells to G1/S blocking. Our findings support the potential of SELK in maintain the health of chicken liver, and indicate that adding proper amount of Se on the daily dietary may alleviate the deficiency of selenium.

J Cell Physiol 2022; 237:3292-3304. [PMID: 35616291 DOI: 10.1002/jcp.30781] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2022] [Revised: 04/17/2022] [Accepted: 05/05/2022] [Indexed: 12/22/2022]
Abstract
Bisphenol A (BPA) in the environment can have deleterious effects on humans and animals. BPA can exert nephrotoxicity by inducing oxidative stress. Selenium (Se) deficiency can specifically impair kidney tissues and additionally show a synergistic effect on the toxicity of several environmental chemicals. However, the toxic effects of BPA on the chicken kidney and whether Se deficiency produces synergistic effects on the toxicity of BPA remain poorly understood. Herein, we established BPA exposure models and Se deficiency model in vivo and in vitro, and described the discovery path of BPA aggravation on apoptosis and necroptosis in Se-deficient chicken kidneys via regulation of oxidative stress and phosphatidylinositol 3-kinase/threonine kinase (PI3K/AKT) signaling pathway. We found that BPA exposure increased reactive oxygen species and malondialdehyde levels, reduced activities of catalase, GPx, and superoxide dismutase, downregulated PI3K and AKT expressions, activated Bcl/Bax-Caspase 9-Caspase 3, and receptor-interacting protein kinase 1/mixed lineage kinase domain-like protein signaling pathways, resulting in apoptosis and necroptosis in the chicken kidney. In addition, Se deficiency significantly promoted the expression of renal apoptosis and necroptosis in BPA-exposed chicken kidneys. Altogether, our results showed that BPA aggravates apoptosis and necroptosis in Se-deficient chicken kidneys via regulation of oxidative stress and PI3K/AKT signaling pathway. Our findings elucidate the mechanism of BPA nephrotoxicity and Se deficiency exacerbation toxicity in chickens and will provide great significance for the protection of the ecological environment and animal health.
