Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Parasitic infections impose a significant burden on public health worldwide. European pharmacopoeia records and ethnopharmacological studies indicate that Hagenia abyssinica (Bruce) J.F. Gmel. has traditionally been used to treat a variety of parasitic infections, while the potential antiparasitic compounds remain ambiguous. AIM OF THE STUDY Acetylcholinesterase (AChE), lactate dehydrogenases (LDH), and glutathione reductase (GR) are the key target enzymes in the survival of parasites. The aim of our work was to screen antiparasitic compounds targeting AChE, LDH, and GR from H. abyssinica. MATERIALS AND METHODS Ultrafiltration-liquid chromatography-mass spectrometry (UF-LC-MS) combined with molecular docking was used in this study. Therein, the alamarBlue® and Ellman's methods were employed to reveal the antitrypanosomal effect and AChE inhibitory activity. Meanwhile, the UF-LC-MS was carried out to screen the potential active compounds from H. abyssinica. Subsequently, molecular docking was performed to evaluate the binding mechanisms of these active compounds with AChE, LDH, and GR. Finally, the AChE inhibitory activity of potential inhibitors was detected in vitro. RESULTS H. abyssinica exhibited significant antitrypanosomal and AChE inhibitory activity. Corilagin, brevifolin carboxylic acid, brevifolin, quercetin, and methyl ellagic acid were recognized as potential AChE inhibitors by UF-LC-MS, while methyl brevifolin carboxylate was identified as AChE, LDH, and GR multi-target inhibitor, with binding degree ranged from 20.96% to 49.81%. Molecular docking showed that these potential inhibitors had a strong affinity with AChE, LDH, and GR, with binding energies ranging from -6.98 to -9.67 kcal/mol. These findings were further supported by the observation that corilagin, quercetin, brevifolin carboxylic acid, and methyl brevifolin carboxylate displayed significant AChE inhibitory activity compared with the positive control (gossypol, 0.42 ± 0.04 mM), with IC50 values of 0.15 ± 0.05, 0.56 ± 0.03, 0.99 ± 0.01, and 1.02 ± 0.03 mM, respectively. CONCLUSIONS This study confirms the antiparasitic potential of H. abyssinica, supporting the traditional use of H. abyssinica in local ethnopharmacology to treat parasites. At the same time, corilagin, brevifolin carboxylic acid, brevifolin, quercetin, methyl ellagic acid, and methyl brevifolin carboxylate exert their anti-parasitic effects by inhibiting AChE, LDH, and GR, and they are expected to be natural lead compounds for the treatment of parasitic diseases.

Abstract
Abalone are frequently exposed to several environmental factors including heavy metal toxicity, thermal stress, H2O2-stress, starvation, viral and bacterial infection that can induce oxidative stress. Glutathione reductase is a vital enzyme in the antioxidant defense system that catalyzes the reduction of oxidized glutathione to reduced glutathione. The present study aimed to identify and localize glutathione reductase in Pacific abalone (Hdh-GR) and assess its potential role in stress physiology, heavy metal toxicity, immune response, gonadal development, and metamorphosis. The mRNA expression of Hdh-GR was upregulated in response to thermal stress, starvation, H2O2-stress, and cadmium-exposed toxicity. The induced mRNA expression was also quantified in immune-challenged abalone. Moreover, the Hdh-GR expression was significantly higher during metamorphosis. The Hdh-GR mRNA expression showed an inverse relationship with ROS production in heat stressed Pacific abalone. These results suggest that Hdh-GR has central role in the stress physiology, immune response, gonadal development, and metamorphosis of Pacific abalone.

Front Cell Infect Microbiol 2022; 12:952720. [PMID: 36601306 PMCID: PMC9806845 DOI: 10.3389/fcimb.2022.952720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Accepted: 09/21/2022] [Indexed: 12/24/2022] Open
Abstract
Neospora caninum is a member of Apicomplexa Phylum and the causative agent of neosporosis, a disease responsible for abortions in cattle. Apicomplexan parasites have a limited set of actin-binding proteins conducting the regulation of the dynamics of nonconventional actin. The parasite actin-based motility is implicated in the parasite invasion process in the host cell. Once no commercial strategy for the neosporosis control is available, the interference in the parasite actin function may result in novel drug targets. Actin-depolymerization factor (ADF) is a member of the ADF/cofilin family, primarily known for its function in actin severing and depolymerization. ADF/cofilins are versatile proteins modulated by different mechanisms, including reduction and oxidation. In apicomplexan parasites, the mechanisms involved in the modulation of ADF function are barely explored and the effects of oxidation in the protein are unknown so far. In this study, we used the oxidants N-chlorotaurine (NCT) and H2O2 to investigate the susceptibility of the recombinant N. caninum ADF (NcADF) to oxidation. After exposing the protein to either NCT or H2O2, the dimerization status and cysteine residue oxidation were determined. Also, the interference of NcADF oxidation in the interaction with actin was assessed. The treatment of the recombinant protein with oxidants reversibly induced the production of dimers, indicating that disulfide bonds between NcADF cysteine residues were formed. In addition, the exposure of NcADF to NCT resulted in more efficient oxidation of the cysteine residues compared to H2O2. Finally, the oxidation of NcADF by NCT reduced the ability of actin-binding and altered the function of NcADF in actin polymerization. Altogether, our results clearly show that recombinant NcADF is sensitive to redox conditions, indicating that the function of this protein in cellular processes involving actin dynamics may be modulated by oxidation.

Abstract
Background. Several toxicants present simultaneously in the environment have combined toxicological effects. In addition, various xenobiotics have distinct effects on oxidative stress biomarkers in animal cells and tissues.
The aim of this study was to analyze the effect of cadmium (Cd) and cyanide (CN) through the food chain on some antioxidant indices in the tissues (lungs, testes, heart, and brain) of male Wistar rats.
Materials and Methods. The study included sixty African catfish allocated to four groups, each comprising fifteen fish, treated with potassium cyanide (KCN) and cadmium chloride (CdCl2), held at a temperature of 25°C in a 100-litre fish tank aquarium with water contaminated with 0.4 mg of both cyanide and cadmium/100 ml of water. All the fish were later killed, dried, and used to prepare diet for experimental animals. Twenty male rats divided into four groups, each comprising five rats, were used for this study as well, and fed for 28 days as follows: Group A - control diet; Group B - cyanide-contaminated diet; Group C - cadmium-contaminated diet; Group D - diet contaminated with cyanide + cadmium. Subsequently, they were sacrificed. Biochemical analysis of the tissues excised from the rats was done.
Results. There was a significant (p < 0.05) increase in lipid peroxidation level and a significant decrease in superoxide dismutase, catalase and reduced glutathione activities in the lungs, testes, heart, and brain of rats fed a catfish diet containing both cyanide and cadmium as compared to controls. In addition, contaminated diet altered acetylcholinesterase activity in the brain, glutathione peroxidase activity, glutathione-S-transferase activity, and glutathione reductase activity in the tissues of experimental rats.
Conclusions. Cadmium and cyanide, via the food chain, induce oxidative stress in the lungs, testes, heart, and brain of rats.

Abstract
Neospora caninum is a protozoan member of the Apicomplexa phylum and is closely connected with abortion in cattle. The development of the parasite in host cells is characterized by the active secretion of proteins, allied to the tight control of the redox status. In this sense, elucidating the mechanisms related to the role of the redox agents and enzymes during the invasion and proliferation of N. caninum may contribute to developing novel forms of neosporosis control. In this study we verified the effects of the recombinant forms of N. caninum glutathione reductase (rNcGR) and thioredoxin-dependent peroxide reductase (rNcPrx), as well as H2O2 in the tachyzoite invasion and proliferation. rNcPrx interfered in the N. caninum invasion in a redox state manner. Oxidized rNcPrx inhibited the N. caninum invasion and proliferation with no toxic effects observed in Vero cells. In contrast, lower concentrations of H2O2 (10 μM) stimulated the N. caninum invasion, which was reverted in higher doses (>100 μM). H2O2 inhibited the parasite proliferation in lower concentrations than cytotoxicity in host cells, resulting in a positive selectivity index (1.8). Besides, rNcPrx (reduced and non-reduced) and rNcGR inhibited the parasite proliferation without affecting the host cell. Our results indicate the connection between the N. caninum development and the redox state, contributing to the elucidation of parasite propagation and control mechanisms.

Abstract
World Health Organisation (WHO) delineated cancer as one of the foremost reasons for mortality with 10 million deaths in the year 2020. Early diagnosis and effective drug delivery are of utmost importance in cancer management. The entrapment of both bio-imaging dyes and drugs will open novel avenues in the area of tumor theranostics. Elevated levels of reactive oxygen species (ROS) and glutathione (GSH) are the characteristic features of the tumor microenvironment (TME). Researchers have taken advantage of these specific TME features in recent years to develop micelle-based theranostic nanosystems. This review focuses on the advantages of redox-sensitive micelles (RSMs) and supramolecular self-assemblies for tumor theranostics. Key chemical linkers employed for the tumor-specific release of the cargo have been discussed. In vitro characterisation techniques used for the characterization of RSMs have been deliberated. Potential bottlenecks that may present themselves in the bench-to-bedside translation of this technology and the regulatory considerations have been deliberated.

Abstract
Neospora caninum, an apicomplexan parasite, is the etiological agent of neosporosis, a disease that leads to neurological symptoms in dogs and abortion in cattle. Vaccine or drug treatments for neosporosis remain to be determined. Therefore, it is of undeniable relevance to investigate new molecules involved in the parasite's successful survival within the host cell. The aim of this study was to characterize the N. caninum peroxiredoxin (NcPrx), an enzyme involved in the redox system of the parasite. The NcPrx amino acid sequence showed high identity and similarity compared to homologues representatives of Apicomplexa phylum. The recombinant NcPrx (rNcPrx) was cloned and expressed in Escherichia coli (BL21) with the predicted molecular weight (22 kDa), and the identity of monomer and dimer forms of rNcPrx was confirmed by mass spectrometry. Native and recombinant NcPrx were detected by ELISA and western blot, using the polyclonal anti-rNcPrx serum. Multiphoton analysis showed that NcPrx is localized in tachyzoite cytosol. H2O2 treatment increased the rNcPrx dimerization in vitro, and associated with the in silico data, we suggest that NcPrx belongs to typical 2-Cys Prx group (AhpC/Prx1 family). rNcPrx also increased the H2O2 clearance and protected plasmidial DNA under oxidative conditions. Finally, H2O2 increased the NcPrx dimerization in intracellular and extracellular tachyzoites suggesting that it is enrolled in H2O2 clearance and sensing in N. caninum.
