Eleiwa NZH, Khalifa HAMI, Nazim HA. Research progress on rat model of drug-induced liver injury established by nonsteroidal anti-inflammatory drug (celecoxib) and royal jelly ameliorative effect. JOURNAL OF COMPLEMENTARY & INTEGRATIVE MEDICINE 2024; 21:239-247. [PMID: 38281144 DOI: 10.1515/jcim-2023-0385] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Accepted: 01/08/2024] [Indexed: 01/30/2024]
Abstract
OBJECTIVES NSAIDs, like celecoxib, are widely used to treat pain, fever, and inflammation, with celecoxib being particularly effective in managing arthritis symptoms and acute or chronic pain especially with its favorable gastrointestinal tolerability. The study aimed at exploring the effect of chronic administration of celecoxib on hepatic tissues in male albino rats. It also examined the royal jelly celecoxib interplay. METHODS 50 male albino rats in 5 equal groups; Group 1: received no drug. Group 2: received celecoxib (50 mg/kg/day, orally), for 30 successive days. Group 3: received celecoxib plus royal jelly (300 mg/kg/day, orally) for 30 successive days. Group 4: received celecoxib, for 30 days, then were left untreated for another 30 days. Group 5: received celecoxib plus royal jelly for 30 days, then were left untreated for another 30 days. RESULTS Chronic celecoxib administration caused hepatotoxicity in male albino rats, with ameliorative effect of royal jelly. Celecoxib discontinuation significantly diminished the celecoxib-induced toxicity, and normal liver enzymes and serum protein levels were regained in the case of dual medications (celecoxib+RJ) discontinuation. CONCLUSIONS Long-term celecoxib administration caused hepatotoxicity, with ameliorative effects of royal jelly against celecoxib-induced oxidative and apoptotic stress. In addition, it could be concluded that royal jelly may prove a useful adjunct in patients being prescribed celecoxib.

Abstract
Few studies on royal jelly's (RJ) antiviral activities and toxicity have been conducted. Here, we investigated the antioxidant properties of RJ that was fractionated into soluble fraction (SF), non-soluble fraction (NSF), water-soluble protein fraction (crude protein fraction, CPF), PF30, PF40, PF50, and PF60. The PFs were identified by SDS-PAGE, and phenolic constituents of SF were detected by HPLC. The qualitative anti-HCV, immunomodulatory, and predicted impact of the studied fractions on ERK2/MAPK14 (activated by HCV) were investigated. The influences of RJ fractions on HIV CD4, reverse-transcriptase, and integrase were examined. The acute toxicity of RJ, SF, NSF, and CPF-PF50 (all CPF except PF50) was tested. Results showed that RJ had potent antioxidant efficiency, and its SF contains functional phenolic compounds. PF30, PF40, and PF50 only showed anti-HCV potency, and PF50 had an immunomodulatory effect against HCV and predicted inhibitory influence on ERK2/MAPK14. RJ-PFs, particularly PF60, showed the most effective anti-HIV ingredients. A single ip injection of RJ fractions at different concentrations revealed that SF was the safest one. Whereas NSF was the most toxic at 700-5000 mg/kg b.w., its toxicity was reversed spontaneously after seven days. Thus, this study provides valuable information about the antiviral activities and toxicity of RJ constituents.

Abstract
Nowadays, royal jelly (RJ) has gained great interest as a functional food due to its valuable pharmacological effects. We investigated the therapeutic potency of combined protein fraction (PF50) of major RJ protein 2 and its isoform X1 on bleomycin (Bleo)-induced pulmonary injury in rats. Our study examined the impact of PF50 on pulmonary oxidative and inflammatory stress as well as smooth muscle alpha-actin (α-SMA). In addition, the predicted impacts of this PF on the activity of matrix metalloproteinase (MMP)- 8 and 15-prostaglandin dehydrogenase (15-PGDH) and the E-type prostanoid 2 (EP2) and IL-13 α2 subunit (IL13α2R) receptors, were evaluated using molecular docking. The results showed that PF50 reduced pulmonary inflammatory cells and their secreted pro-inflammatory mediators, including NF-κB, IKK, IL-4, IL-6, and NO. Additionally, the levels of IgE and mucin were diminished after treatment with PF50. Moreover, PF50 treatment improved pulmonary oxidative stress indices such as lipid peroxidation, GSH, SOD, and GPX. The histopathological findings, chest conventional X-ray, and immunohistochemistry of α-SMA confirmed the ameliorating effect of PF50. The docking outcomes reported the probable competitive inhibitory influence of PF50 on MMP-8 and a postulated blocking effect on EP2 and IL13α2R. Thus, PF50 could be a novel approach for treating pulmonary injuries.

Abstract
Carotenoids come in second among the most frequent natural pigments and are utilized in medications, nutraceuticals, cosmetics, food pigments, and feed supplements. Based on recent complementary work, Virgibacillus was announced for the first time as a member of Wadi El-Natrun salt and soda lakes microbiota, identified as Virgibacillus halodenitrificans, and named V. halodenitrificans DASH; hence, this work aimed to investigate several in vitro medicinal bioactivities of V. halodenitrificans DASH carotenoids. The carotenoid methanolic extract showed antioxidant activity based on diphenylpicrylhydrazyl (DPPH) scavenging capacity with a half-maximal concentration (IC50) of 1.6 mg/mL as well as nitric oxide (NO) scavenging action expressed by an IC50 of 46.4 µg/mL. The extract showed considerable inhibitory activity for alpha-amylase (α-amylase) and alpha-glucosidase (α-glucosidase) enzymes (IC50 of 100 and 173.4 μg/mL, respectively). Moreover, the extract displayed selective anticancer activity against Caco-2 (IC50 = 138.96 µg/mL) and HepG-2 cell lines (IC50 = 31.25 µg/mL), representing colorectal adenocarcinoma and hepatoblastoma. Likewise, the extract showed 98.9 % clearance for human hepatitis C virus (HCV) using reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR), HCV-NS5B polymerase activity inhibition (IC50 = 27.4 µg/mL), and selective inhibitory activity against human coronavirus (HCoV 229E) using the plaque reduction assay (IC50 = 53.5 µg/mL). As far as we can tell, the anticancer, antiviral, and antidiabetic attributes of Virgibacillus carotenoids are, de novo, reported in this work which accordingly invokes further exploration of the other medicinal, biotechnological, and industrial applications of Virgibacillus and haloalkaliphilic bacteria carotenoids.

Abstract
For reasons of high transmissibility and virulence, Alpha (UK, B.1.1.7) and Beta (South African, B.1.351) SARS-CoV-2 variants are classified with other types as variants of concern. Here we report on the influence of royal jelly (RJ) protein fraction (PF)50 (major RJ protein 2 and its isoform X1) on the entry of these variants into the ACE2-human embryonic kidney (HEK) 293 cells using the lentiviral system. The efficiency of PF50 on SARS-CoV-2 replication (RNA-dependent RNA polymerase "RdRp" activity), as well as its impact on bleomycin-induced lung injury in vitro, were also assessed. The PF50 efficiently inhibited infection of kidney cells with the UK and S. African variant spikes of pseudotyped lentivirus particles (IC50 = 7.25 μM and 16.92 μM, respectively) and suppressed the RdRp activity (IC50 = 29.93 μM). Moreover, PF50 displayed protective and therapeutic efficacy against lung injury due to its antioxidant, anti-inflammatory, and angiotensin II blocking activities. The current findings, taken together, offer a novel perspective on PF50 as a promising agent against COVID-19.

Abstract
Carbon tetrachloride (CCl4 ) is known to have hepatotoxic and nephrotoxic effects. During the two-month CCl4 exposure of Wistar rats, propolis extract (PE) and royal jelly (RJ) were added in order to test the potential protective effect against hepato-renal injury. Ketonuria, proteinuria, high creatinine and urea levels are the result of CCl4 -induced nephrotoxicity. Severe disorders of hematological indicators indicate anemia; high values of leukocytes indicate inflammatory condition. Cytogenetic impairments in hepatocytes, aggregation of platelets, and hypoproteinemia indicate severe liver impairment. Results suggest a more significant protective role of RJ compared to PE. Both extracts regulated proteinuria, ketonuria, hypoproteinemia and reduced platelet aggregation in the hepatic circulation. The increase in the number of erythrocytes (RBC) suggest protective effects against anemia; the decrease in the number of leukocytes can be linked to anti-inflammatory effects. PE and RJ have a beneficial effect against hepato-renal injury, anemia and anti-inflammatory conditions caused by CCl4 .

Abstract
Grape seed (GS) oil is one of the potential functional foods. For the first time, we evaluated the therapeutic effects of GS oil saponifiable (Sap)-fraction from black (BSap) and green (GSap) grapes on MCF-7 cells and Ehrlich ascites carcinoma (EAC) in mice. The fatty acid composition of BSap and GSap was determined using gas chromatography-mass spectrometry analysis. Approximately twelve distinct fatty acids were detected in BSap and eleven in GSap. BSap showed a greater cytotoxic effect on MCF-7 cells than GSap did by inducing apoptosis and reducing inflammation, while both grape fractions had superior potency to 5-FU. Furthermore, BSap massively boosted apoptosis and lowered redox potential (Eh) and CD44+ cells in EAC cells of EAC-bearing mice more than GSap, and both fractions were more efficient than 5-FU. Blood tests and liver histopathology revealed significant improvement in EAC-induced pathological alterations with these fractions. The in silico analysis implied the competitive inhibitory impacts of the most abundant fatty acid composites in BSap and GSap on cancer-metastasis-associated proteases (cathepsin B and MMP9). Also, this analysis predicted that the apoptotic action of these Sap fractions is independent of the 5'AMP-activated protein kinase. Therefore, grape Sap-fraction, especially BSap, may be a useful agent for cancer prevention.

M6 with effective direct virucidal and anti-replicative potential against HCV and HSV. Sci Rep 2022; 12:16577.

Abstract
Halophilic archaea is considered an promising natural source of many important metabolites. This study focused on one of the surface-active biomolecules named biosurfactants produced by haloarchaeon Natrialba sp. M6. The production trend was optimized and the product was partially purified and identified using GC-Mass spectrometry. Sequential optimization approaches, Plackett-Burman (PB) and Box-Behnken Designs (BBD) were applied to maximize the biosurfactants production from M6 strain by using 14 factors; pH, NaCl, agitation and glycerol; the most significant factors that influenced the biosurfactant production were used for Response Surface Methodology (RSM). The final optimal production conditions were agitation (150 rpm), glycerol (3%), NaCl (20.8%), pH (12) and cultivation temperature (37°C). GC-Mass spectrometry for the recovered extract revealed the presence of a diverse group of bipolar nature, hydrophobic hydrocarbon chain and charged function group. The majority of these compounds are fatty acids. Based on results of GC-MS, compositional analysis content and Zetasizer, it was proposed that the extracted biosurfactant produced by haloarchaeon Natrialba sp. M6 could be a cationic lipoprotein. The antiviral activity of such biosurfactant was investigated against hepatitis C (HCV) and herpes simplex (HSV1) viruses at its maximum safe doses (20 μg/mL and 8 μg/mL, respectively). Its mode of antiviral action was declared to be primarily via deactivating viral envelopes thus preventing viral entry. Moreover, this biosurfactant inhibited RNA polymerase- and DNA polymerase-mediated viral replication at IC50 of 2.28 and 4.39 μg/mL, respectively also. Molecular docking studies showed that surfactin resided well and was bound to the specified motif with low and accepted binding energies (ΔG = - 5.629, - 6.997 kcal/mol) respectively. Therefore, such biosurfactant could be presented as a natural safe and effective novel antiviral agent.

Abstract
Bronchial asthma is a chronic inflammatory disease marked by inflammation, oxidative stress, and structural remodeling. Here, we prepared two pomegranate fractions from the seed oil, saponifiable (Sap) and unsaponifiable (UnSap). Two organogels (Orgs) were also formulated with the Sap (Org1) or the UnSap (Org2) fraction and beeswax (BW). All preparations were evaluated in vitro for their antioxidant and anti-inflammatory impacts. The transdermal delivery of the most efficient one was evaluated against ovalbumin (OV)-induced bronchial asthma in rats compared to dexamethasone (DEX). The results showed that the prepared pomegranate fractions and BW had considerable amounts of phenolics (flavonoids and tannins) and triterpenoids. Org1 was shown to be the most effective antioxidant and anti-inflammatory fraction with synergistic activities (combination index, 1), as well as having protective and therapeutic influences on OV-sensitized rats. Org1 inhibited the multiple OV-induced signaling pathways, comprising ROS, WNT/β-catenin, and AKT, with an efficiency superior to DEX. Subsequently, the pro-inflammatory (COX-2, NO, and IL-13), and pro-fibrotic (COL1A1) mediators, oxidative stress, and mucin secretion, were all down-regulated. These outcomes were verified by the histopathological results of lung tissue. Collectively, these outcomes suggest that the transdermal delivery of Org1 to OV-sensitized rats shows promise in the protection and treatment of the pathological hallmarks of asthma.

Abstract
Bronchial asthma is a chronic inflammatory airway illness. For the first time, we evaluated the proposed anti-asthmatic protective and therapeutic potency of inhaling Punica granatum juice (PJE) and peel (PPE) extract mixture (PM). Rats were challenged with ovalbumin (OVA) for 23 days and aerosolized with PM before each OVA challenge (protected group) or following the final OVA challenge for 3 days (therapeutic group). Considerable concentrations of phenolics were detected in PJE and PPE. Therefore, PM demonstrated synergistic scavenging abilities of NO and DPPH radicals. It also showed synergistic anti-inflammatory activities against lipopolysaccharide (LPS)-induced inflammation in the white blood cells by lowering the gene expression of CXCR1, CXCR2, IL-6, and IL-8. In addition, PM increased IL-10 gene expression while decreasing NO and TNF-α levels in LPS-exposed cells. Regarding the rats that were protected with PM, they exerted pulmonary pro-oxidant effects but prevented the OVA-induced upregulation of NF-κB, IKK, TNF-α, COX-2, iNOS, IL-13, and COL1A1, as well as MUC5AC and mucin over-secretion. While PM in the therapeutic group improved reactive oxygen species levels and normalized most of the investigated inflammatory and fibrotic mediators and mucin formation, but slightly improved the antioxidant indices. In addition, OVA-induced morphological alterations were massively improved after PM inhalation for short or long periods. Thus, PM inhalation prevented and treated OVA-induced pulmonary inflammation and fibrosis, while the inhalation period between 3 and 23 days needs to be optimized to acquire a better impact on the antioxidant indices.

Abstract
Relapse of leukemia and drug resistance are still the major obstacles to therapy due to leukemia-initiating stem/progenitor cells (LICs); thus, targeting them using safe compounds is crucial. Here, we evaluated the anti-leukemic effect of royal jelly (RJ) components, which had a higher safe concentration (EC100 values) than the chemotherapeutic drug doxorubicin (DOX). The RJ-protein fraction 50 (PF50, precipitated at 40-50% ammonium sulfate saturation) and its constituents, major RJ protein (MRJP) 2 and its isoform X1, exhibited the highest growth inhibitory effect against myeloid NFS-60 and lymphoid Jurkat cell lines. MRJP2 has a nanosize, which may be the reason for its higher anti-leukemic activity than its isoform. These RJ proteins, particularly MRJP2, suppressed LIC-associated oncogenes (GATA2 and Evi-1) and eliminated CD34+ LICs, in contrast to the low anti-LIC efficacy of DOX. MRJP2 demonstrated higher apoptotic activity than its isoform by upregulating p53 and p21-mediated cell cycle arrest. This study also reported the potent inhibitory effect of RJ-proteins on matrix metallopeptidase 10 (metastatic marker) and histone deacetylase 8 (mediates LIC survival) activities. Thus, MRJP2 can be considered a promising novel therapeutic agent for both myeloid and lymphoid leukemia.

Abstract
Over the past few months, numerous studies harnessed in silico methods such as molecular docking to evaluate food compounds for inhibitory activity against coronavirus infection and replication. These studies capitalize on the efficiency of computational methods to quickly guide subsequent research and examine diet-disease relationships, and their sudden widespread utility may signal new opportunities for future antiviral and bioactive food research. Using Coronavirus Disease 2019 (COVID-19) research as a case study, we herein provide an overview of findings from studies using molecular docking to study food compounds as potential inhibitors of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), explore considerations for the critical interpretation of study findings, and discuss how these studies help shape larger conversations of diet and disease.

Abstract
The utilization of fermented foods with health-promoting properties is becoming more popular around the world. Consequently, kefir, a fermented milk beverage made from kefir grains, was shown in numerous studies to be a probiotic product providing significant health benefits. Herein, we assessed the antibacterial and antifungal potential of kefir against a variety of pathogenic bacteria and fungi. This study also showed the effectiveness of kefir in healing wounds in human gastric epithelial cells (GES-1) by (80.78%) compared with control (55.75%) within 48 h. The quantitative polymerase chain reaction (qPCR) results of kefir-treated HCV- or HBV- infected cells found that 200 µg/mL of kefir can eliminate 92.36% of HCV and 75.71% of HBV relative to the untreated infected cells, whereas 800 µg/mL (the highest concentration) completely eradicated HCV and HBV. Moreover, the estimated IC50 values of kefir, at which HCV and HBV were eradicated by 50%, were 63.84 ± 5.81 µg/mL and 224.02 ± 14.36 µg/mL, correspondingly. Kefir can significantly suppress the elevation of TNF-α and upregulate IL-10 and INF-γ in both treated HCV- and HBV-infected cells. High-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS) analysis of kefir revealed the presence of numerous active metabolites which mainly contribute to the antimicrobial, antiviral, and immunomodulatory activities. This study demonstrated, for the first time, the anti-HBV efficacy of kefir while also illustrating the immunomodulatory impact in the treated HBV-infected cells. Accordingly, kefir represents a potent antiviral agent against both viral hepatitis C and B, as well as having antimicrobial and wound healing potential.

Possible Ameliorative Effects of the Royal Jelly on Hepatotoxicity and Oxidative Stress Induced by Molybdenum Nanoparticles and/or Cadmium Chloride in Male Rats. BIOLOGY 2022; 11:biology11030450. [PMID: 35336823 PMCID: PMC8945475 DOI: 10.3390/biology11030450] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Revised: 03/02/2022] [Accepted: 03/08/2022] [Indexed: 01/24/2023]
Abstract
Simple Summary The aim of the present investigation is valuable due to the importance of possible contaminations and negative effects of these cadmium chloride and molybdenum nanoparticles. The physicochemical properties of molybdenum nanoparticles have been characterized, as well as their ultrastructural organization. A rat experimental model was then employed to assess the liver toxicity of molybdenum nanoparticles, even in combination with CdCl2. The toxicity of molybdenum nanoparticles and cadmium chloride was estimated via liver damage by means of chemico-biological markers of liver injury, serum lipids, inflammation, oxidative status, and histological and immunohistochemistry patterns. Moreover, the possible effects of royal jelly were evaluated. The results clarified that both chemicals induced hepatic toxicity with the excessive triggering of reactive oxygen species that induced severe oxidative injury, histological alterations in the hepatic structure, and hepatic ultrastructure. These results are concurrent with obtaining normal biochemical levels in groups either treated with royal jelly or even a combination of royal jelly and two xenobiotics. The royal jelly is considered an essential potential source of natural antioxidants capable of frustrating the effects of oxidative injury, which is considered the main cause of many diseases. Abstract The present study aimed to investigate the effect of the royal jelly (RJ) on hepatotoxicity induced by molybdenum nanoparticles (MoO3-NPs), cadmium chloride (CdCl2), or their combination in male rats at biochemical, inflammation, immune response, histological, and ultrastructural levels. The physicochemical properties of MoO3-NPs have been characterized, as well as their ultrastructural organization. A rat experimental model was employed to assess the liver toxicity of MoO3-NPs, even in combination with CdCl2. Different cellular studies indicate divergent mechanisms, from increased reactive oxygen species production to antioxidative damage and cytoprotective activity. Seventy male rats were allocated to groups: (i) control; (ii) MoO3-NPs (500 mg/kg); (iii) CdCl2 (6.5 mg/kg); (iv) RJ (85 mg/kg diluted in saline); (v) MoO3-NPs followed by RJ (30 min after the MoO3-NPs dose); (vi) CdCl2 followed by RJ; and (vii) a combination of MoO3-NPs and CdCl2, followed by RJ, for a total of 30 successive days. Hepatic functions, lipid profile, inflammation marker (CRP), antioxidant biomarkers (SOD, CAT, GPx, and MDA), and genotoxicity were examined. Histological changes, an immunological marker for caspase-3, and transmission electron microscope variations in the liver were also investigated to indicate liver status. The results showed that RJ alleviated the hepatotoxicity of MoO3-NPs and/or CdCl2 by improving all hepatic vitality markers. In conclusion, the RJ was more potent and effective as an antioxidant over the oxidative damage induced by the combination of MoO3-NPs and CdCl2.

Abstract
The coronavirus disease 2019 (COVID-19) is an epidemic caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). Populations at risk as well as those who can develop serious complications are people with chronic diseases such as diabetes, hypertension, and the elderly. Severe symptoms of SARS-CoV-2 infection are associated with immune failure and dysfunction. The approach of strengthening immunity may be the right choice in order to save lives. This review aimed to provide an overview of current information revealing the importance of bee products in strengthening the immune system against COVID-19. We highlighted the immunomodulatory and the antiviral effects of zinc and polyphenols, which may actively contribute to improving symptoms and preventing complications caused by COVID-19 and can counteract viral infections. Thus, this review will pave the way for conducting advanced experimental research to evaluate zinc and polyphenols-rich bee products to prevent and reduce the severity of COVID-19 symptoms.

Abstract
Royal Jelly (RJ) is a gelatinous white-yellowish fluid, possessing a sour taste and a slight phenolic smell that is secreted by the hypopharyngeal and mandibular salivary glands of the nurse honeybees, and is used in nutrition of larvae and adult queens. Similar to other substances associated with the activities of honeybees, RJ not only contains nutritive components, such as carbohydrates, proteins, peptides, lipids, vitamins, and mineral salts, but also represents a natural ingredient with cosmetic and health-promoting properties. RJ is characterized by remarkable multifunctionality, possessing numerous biological activities. Although this multifunctionality of RJ can be considered as a consequence of its complex nature, many proteins and peptides in RJ are polyfunctional entities themselves. In this article, we show that RJ proteins contain different levels of intrinsic disorder, have sites of post-translational modifications, can be found in multiple isoforms, and many of them possess disorder-based binding sites, suggesting that the conformational ensembles of the RJ proteins might undergo change as a result of their interaction with specific binding partners. All these observations suggest that the multifunctionality of proteins and peptides from RJ is determined by their structural heterogeneity and polymorphism, and serve as an illustration of the protein structure-function continuum concept.

J Food Sci 2021; 86:1105-1113. [PMID: 33580500 DOI: 10.1111/1750-3841.15625] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Revised: 12/29/2020] [Accepted: 01/11/2021] [Indexed: 11/28/2022]
Abstract
Nonalcoholic fatty liver disease (NAFLD) is a metabolic syndrome, whose main characteristics are excessive lipid accumulation and oxidative stress. Major royal jelly proteins (MRJPs) is a kind of water-soluble protein, which is abundant in royal jelly (RJ). The aim of this study was to evaluate the effect of MRJPs on lipid accumulation and oxidative stress of liver cells. Here, we first optimized the conditions for extracting MRJPs from RJ and identified the extraction effect and product by SDS-PAGE. Then, we used oleic acid (OA) of 1.0 mM to induce hepatocytes for 24 hr to establish a stable cell models of lipid accumulation, and we found that pre-administration (24 hr) of MRJPs (0.2, 0.5, and 1.0 g/L) could significantly reduce the lipid drop content and triglyceride level in the model cells, and simultaneously reduce the alanine aminotransferase and aspertate aminotransferase levels in the cell culture supernatant. In addition, pre-incubation (24 hr) with MRJPs (0.2, 0.5, and 1.0 g/L) could restore superoxide dismutase (SOD) level and mitochondrial membrane potential as compared with OA group. Furthermore, MRJPs administration significantly upregulated the expression of Silent Information Regulator 2 Associated Protein 3, mitochondrial superoxide dismutase (SOD2), and cytochrome c oxidase subunit IV in OA-treated HepG2 cells. The study for the first time provides evidences on the lipid-lowering effect of MRJPs at the cellular level, which can further provide support for the development and application of polypeptide drugs in the future, and can also provide a choice for the prevention and treatment of liver metabolic diseases represented by NAFLD. PRACTICAL APPLICATION: Our study proved that MRJPs had substantial preventing effect on OA-induced lipid accumulation and mitochondrial dysfunction in HepG2 cells. This research can further provide theoretical support for the development and application of peptide drugs in the future. Besides, it can not only further broaden our understanding of NAFLD and other diseases, but also provide ideas for research on oxidative stress and lipid accumulation in the body.

J Funct Foods 2020; 75:104282.

Abstract
Severe acute respiratory syndrome-coronavirus (SARS-CoV)-2 is a newly emerging type of CoV. We evaluated the predicted anti-SARS-CoV-2 effect of major royal jelly protein (MRJP)2 and MRJP2 isoform X1, which recently showed high efficacy against other enveloped RNA-viruses (HCV and HIV). Some in-silico analyses have been performed to predict the impact of these proteins on viral entry, replication, and complications. These proteins have shown a high potency in sialic acid hydrolysis from the lung cells (WI-38) surface. Docking analysis showed that these proteins have a high binding affinity to viral receptor-binding sites in the receptor-binding domain, causing attachment prevention. Moreover, MRJPs can exert an inhibitory influence, via different mechanisms, for SARS-CoV-2 non-structural proteins (main and papain proteases, RNA replicase, RNA-dependent RNA polymerase, and methyltransferase). Also, they can bind to hemoglobin-binding sites on viral-nsps and prevent their hemoglobin attack. Thus, MRJP2 and MRJP2 X1 can be a promising therapy for SARS-CoV-2 infection.

Abstract
Halophilic archaea are a promising natural source of carotenoids. However, little information is available about the biological impacts of these archaeal metabolites. Here, carotenoids of Natrialba sp. M6, which was isolated from Wadi El-Natrun, were produced, purified and identified by Raman spectroscopy, GC-mass spectrometry, and Fourier transform infrared spectroscopy, LC-mass spectrometry and Nuclear magnetic resonance spectroscopy. The C50 carotenoid bacterioruberin was found to be the predominant compound. Because cancer and viral hepatitis are serious diseases, the anticancer, anti-HCV and anti-HBV potentials of these extracted carotenoids (pigments) were examined for the first time. In vitro results indicated that the caspase-mediated apoptotic anticancer effect of this pigment and its inhibitory efficacy against matrix metalloprotease 9 were significantly higher than those of 5-fluorouracil. Furthermore, the extracted pigment exhibited significantly stronger activity for eliminating HCV and HBV in infected human blood mononuclear cells than currently used drugs. This antiviral activity may be attributed to its inhibitory potential against HCV RNA and HBV DNA polymerases, which thereby suppresses HCV and HBV replication, as indicated by a high viral clearance % in the treated cells. These novel findings suggest that the C50 carotenoid of Natrialba sp. M6 can be used as an alternative source of natural metabolites that confer potent anticancer and antiviral activities.
