Abstract
This study aimed to screen the bioactive components in Streptococcus equinus WC1 (SE-WC1) and Limosilactobacillus reuteri GM4 (LR-GM4) and estimate the therapeutic role in Ehrlich solid tumors (EST) mice model. Forty-four male albino EST mice were assigned into 7 groups and treated daily for 2 weeks, including the EST group, the EST mice that received SE-WC1 at a low or a high dose (0.5 ml *106 or 0.5 ml *108 cfu), the EST mice that received LR-GM4 at the low or the high dose (0.5 ml *106 or 0.5 ml *108 cfu), and the EST mice that received SE-WC1 plus LR-GM4 at the low or the high dose. Tumors were harvested, weighed, examined, and used for the determination of apoptosis-related gene expression. Samples of the intestine, liver, and kidney were gathered for histological examination. The GC-MS identified 24 and 36 bioactive compounds in SE-WC1 and LR-GM4, respectively. The main compound in SE-WC1 was lupeol; however, the main compound in LR-GM4 was retinaldehyde. EST mice showed disturbances in Bcl-2, Bax, and p53 mRNA expression along with histological changes in the intestine, liver, and kidney. Administration of both bacterial strains reduced the tumor weight, alleviated the disturbances in the gene expression, and improved the histological structure of the intestine, liver, and kidney in a dose-dependent. Moreover, LR-GM4 was more effective than SE-WC1 due to its higher content of bioactive compounds. It could be concluded that these strains of probiotics are promising for the treatment of solid tumors.

Abstract
CONTEXT Aflatoxins are the most harmful mycotoxins that cause human and animal health concerns. Aflatoxin M1 (AFM1) is the primary hydroxylated metabolite of aflatoxin B1 and is linked to the development of hepatocellular carcinoma and immunotoxicity in humans and animals. Because of the important role of dairy products in human life, especially children, AFM1 is such a major concern to humans because of its frequent occurrence in dairy products at concentrations high enough to cause adverse effects to human and animal health. Reduced its bioavailability becomes a high priority in order to protect human and animal health. OBJECTIVES This study aimed to investigate, in vivo, the ability of lactic acid bacteria (lactobacillus rhamnosus GAF01, LR) and clay mineral (bentonite, BT) mixture to mitigate/reduce AFM1-induced immunotoxicity, hepatotoxicity, nephrotoxicity and oxidative stress in exposed Balb/c mice. MATERIALS AND METHODS The in vivo study was conducted using male Balb/c mice that treated, orally, by AFM1 alone or in combination with LR and/or BT, daily for 10 days as follows: group 1 control received 200 µl of PBS, group 2 treated with LR alone (2.108 CFU/mL), group 3 treated with BT alone (1 g/kg bw), group 4 treated with AFM1 alone (100 μg/kg), group 5 co-treated with LR + AFM1, group 6 co-treated with BT + AFM1, group 7 co-treated with BT + LR + AFM1. Forty-eight h after the end of the treatment, the mice were sacrificed and the blood, spleen, thymus, liver and kidney were collected. The blood was used for biochemical and immunological study. Spleen and thymus samples were used to thymocytes and splenocytes assessments. Liver and kidney samples were the target for evaluation of oxidative stress enzymes status and for histological assays. RESULTS The results showed that AFM1 caused toxicities in male Blab/c mice at different levels. Treatment with AFM1 resulted in severe stress of liver and kidney organs indicated by a significant change in the biochemical and immunological parameters, histopathology as well as a disorder in the profile of oxidative stress enzymes levels. Also, it was demonstrated that AFM1 caused toxicities in thymus and spleen organs. The co-treatment with LR and/or BT significantly improved the hepatic and renal tissues, regulated antioxidant enzyme activities, spleen and thymus viability and biochemical and immunological parameters. LR and BT alone showed to be safe during the treatment. CONCLUSION In summary, the LR and/or BT was able to reduce the biochemical, histopathological and immunological damages induced by AFM1 and indeed it could be exploited as one of the biological strategies for food and feedstuffs detoxification.

Streptomyces Bioactive Metabolites Prevent Liver Cancer through Apoptosis, Inhibiting Oxidative Stress and Inflammatory Markers in Diethylnitrosamine-Induced Hepatocellular Carcinoma. Biomedicines 2023; 11:biomedicines11041054.

Abstract
A safe and effective treatment for liver cancer is still elusive despite all attempts. Biomolecules produced from natural products and their derivatives are potential sources of new anticancer medications. This study aimed to investigate the anticancer potential of a Streptomyces sp. bacterial extract against diethylnitrosamine (DEN)-induced liver cancer in Swiss albino mice and explore the underlying cellular and molecular mechanisms. The ethyl acetate extract of a Streptomyces sp. was screened for its potential anticancer activities against HepG-2 using the MTT assay, and the IC50 was also determined. Gas chromatography-mass spectrometric analysis was used to identify the chemical constituents of the Streptomyces extract. Mice were administered DEN at the age of 2 weeks, and from week 32 until week 36 (4 weeks), they received two doses of Streptomyces extract (25 and 50 mg/kg body weight) orally daily. The Streptomyces extract contains 29 different compounds, according to the GC-MS analysis. The rate of HepG-2 growth was dramatically reduced by the Streptomyces extract. In the mice model. Streptomyces extract considerably lessened the negative effects of DEN on liver functions at both doses. Alpha-fetoprotein (AFP) levels were significantly (p < 0.001) decreased, and P53 mRNA expression was increased, both of which were signs that Streptomyces extract was suppressing carcinogenesis. This anticancer effect was also supported by histological analysis. Streptomyces extract therapy additionally stopped DEN-induced alterations in hepatic oxidative stress and enhanced antioxidant activity. Additionally, Streptomyces extract reduced DEN-induced inflammation, as shown by the decline in interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) levels. Additionally, the Streptomyces extract administration dramatically boosted Bax and caspase-3 levels while decreasing Bcl-2 expressions in the liver according to the Immunohistochemistry examination. In summary, Streptomyces extract is reported here as a potent chemopreventive agent against hepatocellular carcinoma through multiple mechanisms, including inhibiting oxidative stress, cell apoptosis, and inflammation.

Li M, Kong Y, Guo W, Wu X, Zhang J, Lai Y, Kong Y, Niu X, Wang G. Dietary aflatoxin B 1 caused the growth inhibition, and activated oxidative stress and endoplasmic reticulum stress pathway, inducing apoptosis and inflammation in the liver of northern snakehead (Channa argus). THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 850:157997. [PMID: 35964742 DOI: 10.1016/j.scitotenv.2022.157997] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 07/31/2022] [Accepted: 08/09/2022] [Indexed: 06/15/2023]
Abstract
The purpose of this study was to investigate the effects of dietary aflatoxin B1 (AFB1) on growth performance and AFB1 biotransformation, and hepatic oxidative stress, endoplasmic reticulum (ER) stress, apoptosis, and inflammation in northern snakehead (Channa argus). A total of 600 northern snakeheads (7.52 ± 0.02 g) were divided into five groups (three replicates/group) and fed the diets with AFB1 at concentrations of 0, 50, 100, 200, and 400 ppb for 8 weeks. The results demonstrated that dietary AFB1 (≥ 200 ppb) reduced FBW, WG, and SGR. 100, 200, and 400 ppb AFB1 treatment groups significantly decreased the PER, CRP, C3, C4, IgM, and LYS levels in northern snakehead, while FCR was significant increased. Moreover, dietary AFB1 (100, 200, and 400 ppb) increased cyp1a, cyp1b (except 400 ppb), and cyp3a mRNA expression levels, while reducing the GST enzymatic activity and mRNA expression levels in northern snakehead. Furthermore, AFB1 (≥ 100 ppb) increased ROS, MDA, and 8-OHdG levels, and grp78, ire1, perk, jnk, chop, and traf2 mRNA expression levels, and decreased SOD, CAT, GSH-Px, and GSH (except 100 ppb) levels and the gene expression levels of cat, gsh-px (except 100 ppb), and Cu/Zn sod. In addition, AFB1 (100, 200, and 400 ppb) up-regulated the cyt-c, bax, cas-3, and cas-9 mRNA levels in the liver, while down-regulating the bcl-2 expression levels. Meanwhile, the expression levels of nf-κb, tnf-α (except 100 ppb), il-1β, and il-8 in the liver were up-regulated in AFB1 treatment groups (≥ 100 ppb), while the iκbα mRNA levels were down-regulated. In summary, dietary AFB1 reduced growth performance and humoral immunity in northern snakehead. Meanwhile, the cyclic occurrence of oxidative stress and ER stress, and induced apoptosis and inflammation, is one of the main reasons for AFB1-induced liver injury in the northern snakehead, which will provide valuable information and a fresh perspective for further research into AFB1-induced liver injury in fish.

Costus speciosus extract protects against the oxidative damage of zearalenone via modulation of inflammatory cytokines, Nrf2 and iNOS gene expression in rats. Toxicon 2022; 214:62-73. [PMID: 35597521 DOI: 10.1016/j.toxicon.2022.05.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2022] [Revised: 05/06/2022] [Accepted: 05/11/2022] [Indexed: 11/17/2022]
Abstract
Zearalenone (ZEN) is a non-steroidal estrogenic mycotoxin that induces severe health disturbances in humans and animals. This study aimed to determine the bioactive compounds in Costus speciosus extract (CSE) using GC-MS and evaluate its protective capability against ZEN-induced oxidative damage, genotoxicity, and cytotoxicity in rats. Six groups of male Sprague Dawley rats were treated orally for 15 days including the control group, CSE-treated groups at low (200 mg/kg b. w) or high (400 mg/kg b. w) dose, ZEN-treated group (40 μg/kg b. w), and the groups treated with ZEN plus the low or the high dose of CSE. Blood and tissue samples were collected for different assays and pathological analyses. The results of GC-MS indicated the identification of 6 compounds and Azulene was the major. Animals that received ZEN showed severe disturbances in serum biochemical, cytokines, oxidative stress indicators, mRNA expression of iNOS, Nrf2, and inflammatory-related genes. ZEN also increased micronucleated polychromatic erythrocytes (MNPCEs) and comet tail formation in bone marrow cells along with the disturbances in the histological architecture of the liver and kidney. Co-administration of CSE plus ZEN could normalize the majority of the tested parameters and the histological picture at a dose as low as 200 mg/kg b. w. Therefore, CSE protects against ZEN toxicity via its antioxidant activity, modulation of iNOS, inflammatory-related genes, and the Nrf2 pathway and it could be used in the endemic regions.

Abstract
This study aimed to assess the protective effect of encapsulating humic acid-iron complexed nanoparticles (HA-Fe NPs) inside glucanmannan lipid particles (GMLPs) extracted from yeast cell wall against aflatoxin B (AFB1 ) toxicity in vivo. Four groups of male Sprague-Dawley rats were treated orally for 2 weeks included the control group, AFB1 treated group (80 µg/kg b.w); GMLP/HA-Fe NPs treated group (0.5 mg/kg b.w), and the group treated with AFB1 plus GMLP/HA-Fe NPs. GMLPs are empty 3-4 micron permeable microspheres that provide an efficient system for the synthesis and encapsulation of AFB1 -absorbing nanoparticles (NPs). Humic acid nanoparticles (HA-NPs) were incorporated inside the GMLP cavity by complexation with ferric chloride. In vivo study revealed that AFB1 significantly elevated serum alanine aminotransferase, aspartate aminotransferase, creatinine, uric acid, urea, cholesterol, triglycerides, LDL, malondialdehyde, and nitric oxide. It significantly decreased total protein, high-density lipoprotein, hepatic and renal CAT and glutathione peroxidase content and induced histological changes in the liver and kidney (p ≤ 0.05). The coadministration of the synthesized formulation GMLP/HA-Fe NPs with AFB1 has a protective effect against AFB1 -induced hepato-nephrotoxicity, oxidative stress and histological alterations in the liver and kidney.

Abstract
Free radicals are highly reactive unstable molecules, which can be synthesized in different ways, considered harmful and threatening to humans; these chemical species have free traffic throughout the human body, interacting with biological molecules and human body organ tissues. The interaction between free radicals and biological molecules is the main factor for disease development or pre-existing disease symptoms aggravation. Antioxidants are chemical compounds able to donate electric charge to stabilize molecules such as free radicals. Recent studies have proved the benefits of antioxidants intake in health improvement. In this way, the search for natural sources of antioxidants has become an ascending trend. In this field, the microbial sources are considered poorly explored compared to the numerous amount of other compounds obtained from them, especially from Actinobacteria. The searched literature about Actinobacteria highlights an important capacity of producing natural antioxidants; however, there is a lack of in vivo studies of these isolated compounds. In this review, we gathered information that supports our point of view that Actinobacteria is a truly renewable and superficially explored source of natural antioxidants. Furthermore, our purpose is also to point this limitation and stimulate more researches in this area.

Abstract
Mycotoxins are metabolites produced by fungi. The widespread contamination of food and feed by mycotoxins is a global food safety problem and a serious threat to people's health. Most food-borne mycotoxins have strong hepatotoxicity. However, no effective methods have been found to prevent or treat Mycotoxin- Induced Liver Injury (MILI) in clinical and animal husbandry. In this paper, the molecular mechanisms and potential anti-MILI medicines of six food-borne MILI are reviewed, and their targets are predicted by network toxicology, which provides a theoretical basis for further study of the toxicity mechanism of MILI and the development of effective strategies to manage MILI-related health problems in the future and accelerate the development of food safety.

Abstract
Crop infections by fungi lead to severe losses in food production and pose risks for human health. The increasing resistance of pathogens to fungicides has led to the higher usage of these chemicals, which burdens the environment and highlights the need to find novel natural biocontrol agents. Members of the genus Streptomyces are known to produce a plethora of bioactive compounds. Recently, researchers have turned to extreme and previously unexplored niches in the search for new strains with antimicrobial activities. One such niche are underground coal mine environments. We isolated the new Streptomyces sp. MW-W600-10 strain from coal mine water samples collected at 665 m below ground level. We examined the antifungal activity of the strain against plant pathogens Fusarium culmorum DSM62188 and Nigrospora oryzae roseF7. Furthermore, we analyzed the strain’s biosynthetic potential with the antiSMASH tool. The strain showed inhibitory activity against both fungi strains. Genome mining revealed that it has 39 BGCs, among which 13 did not show similarity to those in databases. Additionally, we examined the activity of the Streptomyces sp. S-2 strain isolated from black soot against F. culmorum DSM62188. These results show that coal-related strains could be a source of novel bioactive compounds. Future studies will elucidate their full biotechnological potential.

C30 expressed in Saccharomyces cerevisiae: A mechanism assessment study in vitro and in vivo. Food Res Int 2021; 145:110418. [PMID: 34112421 DOI: 10.1016/j.foodres.2021.110418] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Revised: 04/06/2021] [Accepted: 05/11/2021] [Indexed: 12/21/2022]
Abstract
Aflatoxin B1 (AFB1) is the most harmful mycotoxin and presents risks to human health. Utilization of enzyme to degrade AFB1 is a promising strategy to overcome this problem. In this study, we evaluated the effect of recombinant laccase expressed in Saccharomyces cerevisiae on the degradation of AFB1. It was found that AFB1 could be degraded effectively by laccase up to 91%.The results of ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS) showed that there were four main degradation products of AFB1 including C16H22O4, C14H16N2O2, C7H12N6O and C24H30O6. Two possible degradation pathways were proposed: 1) AFB1 lost -CO continuously, and then double bonds of furan ring were broken after reactions with H2O, H+, and -NH2; 2) AFB1 occurred decarbonylation reaction after losing -CO and double bonds were broken by additional reaction with H+. Two toxicological activity sites in AFB1, including a double bond of furo-furan ring and lactone ring in the coumarin in moiety, were destroyed. The toxicity of AFB1 degradation products was evaluated on HepG2 cells and in vivo tests, and the results indicated a decrease in hepatocytes apoptosis, liver and kidney histopathological lesions, oxidative stress, and inflammation as compared to non-laccase degraded AFB1. Moreover, the AFB1 degradation products significantly decreased the cytotoxicity and hepatotoxicity. This investigation provides innovative evidence on the effectiveness of laccase expressed in Saccharomyces cerevisiae in detoxifying AFB1.

Abstract
This study aimed to identify the bioactive compounds of the ethyl acetate extract of Aspergillus niger SH2-EGY using GC-MS and to evaluate their protective role against aflatoxin B1 (AFB1)-induced oxidative stress, genotoxicity and cytotoxicity in rats. Six groups of male Sprague-Dawley rats were treated orally for 4 weeks included the control group, AFB1-treated group (80 μg/kg b.w); fungal extract (FE)-treated groups at low (140) or high dose (280) mg/kg b.w and the groups treated with AFB1 plus FE at the two tested doses. The GC-MS analysis identified 26 compounds. The major compounds found were 1,2,3,4,6-Penta-trimethylsilyl Glucopyranose, Fmoc-L-3-(2-Naphthyl)-alanine, D-(-)-Fructopyranose, pentakis (trimethylsilyl) ether, bis (2-ethylhexyl) phthalate, trimethylsilyl ether-glucitol, and octadecanamide, N-(2- methylpropyl)-N-nitroso. The in vivo results showed that AFB1 significantly increased serum ALT, AST, creatinine, uric acid, urea, cholesterol, triglycerides, LDL, carcinoembryonic antigen, alpha-fetoprotein, interleukin-6, Malondialdehyde, nitric oxide, Bax, caspase-3 and P53 mRNA expression, chromosomal aberrations and DNA fragmentation. It decreased serum TP, albumin, HDL, Bcl-2 mRNA expression, hepatic and renal TAC, SOD and GPx content and induced histological changes in the liver and kidney. FE prevented these disturbances in a dosage-dependent manner. It could be concluded that A. niger SH2-EGY extract is safe a promising agent for pharmaceutical and food industries.

Abstract
The aim of this study was to investigate the potential protective effect of two extracts derived from two soil actinomycete strains, designated S19 and G30, against CCl4-induced hepatotoxicity in male rats. Sixty-four male rats were divided into four groups of 16 rats per group. The first group was a control group given corn oil and the nutritive medium which is composed of a mixture of the two used media. The second group received CCl4 only, the third group was administered CCl4 and the extract S19, and the fourth group was administered CCl4 and the extract G30. The results were taken after a treatment period of 8 weeks. Our data demonstrated that the two actinomycete extracts significantly (P < 0.01) lowered the CCl4-induced elevation of serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) after 8 weeks of treatment. The extract S19 had no effect on serum lactate dehydrogenase (LDH) and total bilirubin, whereas the extract G30 significantly decreased (P < 0.01) the elevated levels of these parameters in the serum, especially after 4 weeks of treatment. The levels of hepatic glutathione (GSH), glutathione peroxidase (GSH-Px), peroxidase (Px), catalase (CAT), and superoxide dismutase (SOD) significantly increased (P < 0.01), while those of malondialdehyde (MDA) markedly decreased in rats treated with the two extracts. Furthermore, histopathological lesions in the liver, including necrosis, inflammatory cell infiltration, hydropic degeneration, and congestion of the central vein, were partially reversed by treatment with the two microbial extracts. Our results provided evidence for the protective effect of the two used actinomycete extracts against CCl4-induced liver damage occurred through the reduction of oxidative stress and improvement of antioxidant defense markers.

Abstract
Fumonisin B1 (FB1) and aflatoxin B1 (AFB1) are fungal metabolites that frequently co-occur in foodstuffs and are responsible for mycotoxicosis and several primary cancers. Cinnamon essential oil (CEO) has a spacious range of benefit effects but also has some limitations owing to its strong taste or its interaction with some drugs. This study aimed to use the cinnamon oil emulsion droplets (COED) for the protection against oxidative stress, cytotoxicity, and reproductive toxicity in male Sprague-Dawley rats sub-chronically exposed to FB1 and/or AFB1. The composition of CEO was identified using GC-MS then was encapsulated using whey protein as wall material. Male rats were divided into eight groups and treated orally for 8 weeks as follows: control group, AFB1-trreated group (80 μg/kg b.w), FB1-treated group (100 mg/kg b.w), FB1 plus AFB1-treated group, and the groups treated with COED plus FB1 and/or AFB1. Blood and samples of the kidney, liver, and testis were collected for different analysis and histopathological examination. The GC-MS analysis revealed that cinnamaldehyde, α-copaene, trans-cinnamaldehyde, caryophyllene, and delta-cadinene were the main compounds in COE. The average size of COED was 235 ± 1.4 nm and the zeta potential was - 6.24 ± 0.56. Treatment with FB1 and/or AFB1 induced significant disturbances in the serum biochemical analysis, oxidative stress parameters, DNA fragmentation, gene expression, and testosterone and severe pathological changes in the tested organs. Moreover, treatment with both mycotoxins induced synergistic toxic effects. COED did not induce toxic effects and could normalize the majority of the tested parameters and improve the histological picture in rats treated with FB1 and/or AFB1. It could be concluded that COED induce potential protective effects against the single or combined exposure to FB1 and AFB1.

Abstract
Deoxynivalenol (DON) is a Fusarium mycotoxin that frequently contaminates cereal and cereal-based food and induces liver injury. This study evaluated the protective role of silymarin nanoparticles (SILNPs) and inulin nanoparticles (INNPs) against DON-induced liver injury in rats. Eleven groups of rats were treated orally for 3 weeks as follows: the control group, DON-treated group (5 mg/kg b.w.); INNPs-treated groups at low (LD) or high (HD) dose (100 or 200 mg/kg b.w.); SILPNs-treated group (50 mg/kg b.w.); SILNPs plus INNPs(LD) or INNPs(HD)-treated groups; INNPs(LD) or INNPs(HD) plus DON-treated groups and DON plus SILNPs and INNPs(LD) or INNPs(HD)-treated groups. Blood and tissue samples were collected for different analyses. The results revealed that the practical sizes were 200 and 98 nm for SILNPs and INNPs respectively. DON increased liver enzymes activity, lipid profile, serum cytokines, number and percentage of chromosomal aberration, DNA fragmentation and comet score. It disturbed the oxidative stress markers, down regulated gene expression and induced histological changes in the liver tissue. Treatment with DON and SILNPs and/or INNPs at the two tested doses improved all the tested parameters and SILNPs plus INNPs(HD) normalized most of these parameters in DON-treated animals. SILNPs and INNPs could be promising candidates as hepatoprotective against DON or other hepatotoxins.
