[PMID: 34795699 PMCID: PMC8564866 DOI: 10.1590/1678-9199-jvatitd-2020-0152] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2020] [Accepted: 04/09/2021] [Indexed: 01/21/2023] Open
Abstract
Peptides obtained from different animal species have gained importance recently due to research that aims to develop biopharmaceuticals with therapeutic potential. In this sense, arthropod venoms have drawn attention, not only because of their toxicity but mainly for the search for molecules with various bioactivities, including anti-inflammatory activity. The purpose of the present study is to gather data available in the literature on new peptides derived from arthropod species with anti-inflammatory potential. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Studies on peptides from arthropods that display anti-inflammatory activity were retrieved from PubMed, Scopus, Web of Science, and Google Scholar databases. The bibliographic research started in 2020 and searched papers without a limit on the publication date. The articles were analyzed using a search string containing the following terms: "Peptides" and "Anti-inflammatory", in combinations such as "Ant", "Bee", "Wasp", "Crab", "Shrimp", "Scorpion", "Spider", "Tick" and "Centipedes". Besides, a search was carried out in the databases with the terms: "Peptides", "Antitumor", or "Anticancer", and "Arthropods". Articles that met the inclusion and exclusion criteria totalized 171, and these served for data extraction. Additionally, the present review included anti-inflammatory peptides with anticancer properties. Peptides with confirmed anti-inflammatory activity were from insects (ants, bees, and wasps), crustaceans (shrimp and crabs), arachnids (scorpions, spiders, and ticks), and centipedes. These arthropod peptides act mainly by decreasing pro-inflammatory cytokines as analyzed in vitro and in vivo. Some showed significant antineoplastic activity, working in essential cellular pathways against malignant neoplasms.

Abstract
Many active molecules used in the development of new drugs are produced by ants. Present study assessed antioxidant and anti-inflammatory properties of Samsum ant venom (SAV) extract in carbon tetrachloride (CCL4)-induced spleen toxicity. Toxicity and oxidative stress were measured in four experimental groups: a negative control group without any treatment, a positive control group (CCl4-treated rats; a single dose of 1 ml/kg CCL4), an experimental group of CCl4-treated rats co-treated daily with SAV (100 μl), and a group to determine safe use with rats treated only with SAV (100 μl) daily for 3 weeks. CCl4-treatment led to an elevation in toxicity and oxidative stress. CCl4 significantly elevated malondialdehyde (MDA) levels, as well as expression of inhibitor of κB (IκB) and tumor necrosis factor-α (TNF-α) proteins. On the other hand, a decrease in glutathione (GSH) and catalase (CAT) levels were detected in CCl4-treated rats. Co-treatment with SAV was found to reduce these inflammatory and oxidative parameters. SAV elucidated a significant recovery of MDA concentration as well as a significant restoration in GSH levels compared to CCl4-treated rats; however, SAV increased CAT levels compared to normal rats. Hence, SAV was found to restore splenomegaly induced in CCl4-treated rats. Histopathological analysis also favored the biochemical analysis showing improvement in splenic architecture in CCl4 and SAV co-treated rats. The antioxidant properties of SAV may potentially enhance anti-inflammatory actions and improve spleen structure and function in CCl4-challenged rats.

Abstract
BACKGROUND For many decades, the sting of Samsun ant (Pachycondyla sennaarensis) has been a serious clinical challenge for the people living in some of the major Middle East and Asian countries. In the present study, the therapeutic potential of Nigella sativa derived plant extract component, thymoquinone (TQ) has been tested against the Samsun ant venom (SAV) at the toxic dose in the rats. METHODS The adult male rats were divided into four groups (n = 10): control, SAV treated, SAV + TQ treated and TQ alone treated. It was found that the sub-lethal dose of SAV alters not only many of the kidney and liver function markers but also induces oxidative stress in the animals. Moreover, the SAV also disturbs various immunological parameters including expression of PMNs, CD-80, CD-86, interleukins and other cytokines compromising the affected organism towards mild to severe allergic reactions including life-risking anaphylaxis. RESULTS The plant extract, TQ, effectively restores many of the biochemical and oxidative stress parameters comparable to the normal concomitant with improving the immunological aspects that might attributive in relieving from SAV-induced toxicity and allergic reactions in the affected organism to a greater extent. CONCLUSION Hence, TQ has an excellent antidote property against SAV-induced toxicities in vivo. Although the study is a vivid indication of the potential therapeutic potential of TQ against the SAV induced in vivo toxicity, yet the actual mechanism of interaction translating the toxicity amelioration warrants further investigations.

J Venom Anim Toxins Incl Trop Dis 2019; 25:e20190020. [PMID: 31839800 PMCID: PMC6892565 DOI: 10.1590/1678-9199-jvatitd-2019-0020] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2019] [Accepted: 11/05/2019] [Indexed: 01/02/2023] Open
Abstract
BACKGROUND Ant venoms express surface molecules that participate in antigen presentation involving pro- and anti-inflammatory cytokines. This work aims to investigate the expression of MHC-II, CD80 and CD86 on the polymorphonuclear cells (PMNs) in rats injected with samsum ant venom (SAV). METHODS Rats were divided into three groups - control, SAV-treated (intraperitoneal route, 600 μg/kg), and SAV-treated (subcutaneous route, 600 μg/kg). After five doses, animals were euthanized and samples collected for analysis. RESULTS The subcutaneous SAV-trated rats presented decreased levels of glutathione with increased cholesterol and triglyceride levels. Intraperitoneal SAV-treated animals displayed significantly reduced concentrations of both IFN-γ and IL-17 in comparison with the control group. However, intraperitoneal and subcutaneous SAV-treated rats were able to upregulate the expressions of MHC-II, CD80 and CD86 on PMNs in comparison with the control respectively. The histological examination showed severe lymphocyte depletion in the splenic white pulp of the intraperitoneal SAV-injected rats. CONCLUSION Stimulation of PMNs by SAV leads to upregulation of MHC-II, CD 80, and CD 86, which plays critical roles in antigen presentation and consequently proliferation of T-cells. Subcutaneous route was more efficient than intraperitoneal by elevating MHC-II, CD80 and CD86 expression, disturbing oxidative stability and increasing lipogram concentration.

Copper Mediates Anti-Inflammatory and Antifibrotic Activity of Gleevec in Hepatocellular Carcinoma-Induced Male Rats. Can J Gastroenterol Hepatol 2019; 2019:9897315.

Abstract
The elevated level of copper is one of the hallmark features of cancer cells in most of the types of cancer. In the present study, this feature has been targeted to investigate if coadministration of exogenous copper (Cu+) and its chelating agent like disulfiram (DSF+) influence the antineoplastic activity of the anticancer drug, Gleevec (GLV+), in hepatocellular carcinoma (HCC)-induced rats via immunomodulation. After the treatment, the level of proinflammatory interleukins (IL-1, 2, 6, and 7), anti-inflammatory interleukin (IL-10) concomitant with transcription factors (NF-kB and TNF-a), and the apoptotic marker (cleaved PARP) was estimated. The cancer-induced group without treatment (CN+) demonstrated abnormally elevated level of all proinflammatory cytokines and transcription factors concomitant with a compromised level of cleaved PARP as compared to the control normal (CN-). The detailed histological analysis also supported the results exhibiting extensive inflammation and tissue fibrosis confirming the second stage of HCC. Cu+, DSF+, and GLV+ displayed mild improvement in most of the parameters, but the combination group GLV + Cu+ demonstrated remarkable recovery in histology and most of the parameters tended towards the CN- followed by GLV + DSF+. Therefore, the management of copper level is critical in realizing the antineoplastic activity of GLV up to its full potential in cancer treatment. These findings will help in improving chemoimmunotherapy and personalized cancer treatment.

Abstract
Samsum ant venom (SAV) is a rich repertoire of natural compounds with tremendous pharmacological properties. The present work explores its antineoplastic activity in different cell lines followed by its confirmation in vivo. The cell lines, HepG2, MCF-7, and LoVo showed the differential dose-dependent antineoplastic effect with an increased level of significant cytokines, including Interleukin (IL)-1β, IL-6, and IL-8 and transcription factor, Nuclear factor-kappa B (NF-κB). However, the venom was more effective on HepG2 and MCF-7 cells than LoVo cells. Furthermore, the extract was administered to four groups (n = 8) of rats. Group I was taken as a control without any treatment, whereas group II received CCl4 (1 mL/kg) for induction of mild hepatoma. Group III was given 100 μg/kg of SAV twice a week for 1 month. Group IV was pretreated with the CCl4 (like group II) followed by dosing with SAV (100 μg/kg) for 2 months as per the authors' prestandardized dosing schedule. Intriguingly, the rats of group IV demonstrated significant decrease in key cytokines, IL-1β and IL-6, as well as the transcription factors, including Tumor Necrosis Factor-alpha (TNF-α), NF-κB, and Inhibitor-kappa B (I-κB) as compared with group II. Furthermore, increase in IL-10 and First apoptosis signal (FAS) in the same group confirmed that SAV induces apoptosis at the given dose through immunomodulation leading to enhanced tumor killing in vivo. Hence, SAV has an excellent antineoplastic activity that can be directly used to treat certain types of cancer. Moreover, study of its ingredients can pave ways to design novel anticancer drugs. However, further in-depth investigation is required before its clinical trials.

Abstract
Background Ant venom shows antimicrobial, anti-parasitic and anti-inflammatory activities, both in vitro and in vivo. Our recent studies have confirmed the role of samsum ant venom (SAV) as a powerful antioxidant. This study aimed to investigate whether SAV as a potential treatment for CCl4-induced acute liver toxicity in an animal (rat) model. Methods Thirty-two rats were assigned into four groups; the first one served as the control. The second group received a single dose of 1 ml/kg CCl4 in a 1:1 ratio with olive oil through an intraperitoneal injection. The third group received a single dose of 1 ml/kg CCl4 and then treated with SAV at a dose of 100 μg SAV twice a week for three weeks. The fourth group received a dose of 100 μg SAV only twice a week for three weeks. ELISA, RT-PCR and histopathological examinations were applied. Results Results showed that antioxidant enzymes were significantly reduced in the diseased animals. SAV was found to significantly restore the oxidative stability in diseased animals. ELISA estimation and RT-PCR analysis also showed significant upregulation of both nuclear factor (κB) NF-κB and inhibitor (κB) IκB, respectively, in the diseased animals compared to the normal ones. The expression of tumour necrosis factor alpha (TNF-α) and pro-apoptotic receptor (Fas) were also significantly up-regulated in the diseased rats. Interestingly, SAV was found to significantly restore NF-κB, IκB and TNF-α in the diseased rats to the normal values. As a result, liver enzymes, serum proteins and lipid concentrations were significantly improved by SAV in CCl4-animals in comparison with the control ones. Moreover, SAV obviously improved the hepatic tissues of the same group was. Conclusion SAV treatment restores the normal biochemical and oxidative stability by improving the TNF-α/NF-κB mediated inflammation in CCL4-treated rats.

Abstract
BACKGROUND Diabetes mellitus alters oxidative stability and immune response. Here, we investigated the impact of a peptide extracted from camel milk (CMP) on the oxidative status, transcription factor kappa-B (NF-kB) and inflammatory cytokine in diabetic wounds. METHODS Rats were assigned into three groups: control, diabetic induced (DM) and diabetic induced with multiple doses of CMP for a week (DM-CMP). RESULTS DM showed a sharp decline in the activity of major antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT) and glutathione (GSH) compared to the control. The DM-CMP group, however, showed a noticeable replenishment in the activity of these enzymes compared to the DM group. The CMP-treated group also showed a normal level of lipid peroxidation marker (MDA) compared to the DM rats. Furthermore, ELISA analysis of serum TNF-α protein showed an elevated level in diabetic rats in comparison to control serum. However, RT-PCR analysis of locally wounded skin tissues revealed that diabetes down-regulates the RNA expression of both TNF-α and MIF genes in comparison to the control samples but that CMP was found to restore RNA expression significantly. Although it was elevated in CMP-treated rats after one day of wound incision, the NF-kB protein level was significantly decreased seven days after the incision in comparison to the animals in the diabetic group. CONCLUSION CMP, therefore, can be seen an effective antioxidant and immune stimulant that induces oxidative stability and speeds up wound healing in diabetic model animals, making it a potential adjuvant in improving wound healing in those with diabetic conditions.

Antioxidant bioactivity of Samsum ant (Pachycondyla sennaarensis) venom protects against CCL₄-induced nephrotoxicity in mice. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2014; 2014:763061.

Abstract
To assess whether SAV could influence the effects of carbon tetrachloride (CCL4) exposure, mice were treated with SAV in doses of 100, 200, 300 and 400 μg/kg body weight and the effects on oxidative status and kidney function were studied. Serum levels of creatinine, malondialdehyde (MDA), and blood urea, together with renal and hepatic levels of MDA, glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) were quantified in order to evaluate antioxidant activity. Results showed that the group injected with CCL4 exhibited significantly higher levels of oxidative stress markers, MDA, and significantly lower concentrations of GSH, SOD and catalase. SAV was found to significantly improve these oxidative markers, occasionally, in a dose-dependent manner. Furthermore, treatment with SAV was associated with the same behaviour in respect to kidney functions which had previously been impaired by CCL4. Histopathological examination demonstrated that SAV, in different groups, improved the renal tissue damage induced by CCL4 and histological scores confirmed that significant improvements were obtained after treatment with SAV, particularly with the lowest dose (100 μg/kg body weight). In conclusion, SAV has the potential capability to restore oxidative stability and to improve kidney functions after CCL4 acute injury.

Abstract
Background Dinoponera quadriceps is a predatory giant ant that inhabits the Neotropical region and subdues its prey (insects) with stings that deliver a toxic cocktail of molecules. Human accidents occasionally occur and cause local pain and systemic symptoms. A comprehensive study of the D. quadriceps venom gland transcriptome is required to advance our knowledge about the toxin repertoire of the giant ant venom and to understand the physiopathological basis of Hymenoptera envenomation. Results We conducted a transcriptome analysis of a cDNA library from the D. quadriceps venom gland with Sanger sequencing in combination with whole-transcriptome shotgun deep sequencing. From the cDNA library, a total of 420 independent clones were analyzed. Although the proportion of dinoponeratoxin isoform precursors was high, the first giant ant venom inhibitor cysteine-knot (ICK) toxin was found. The deep next generation sequencing yielded a total of 2,514,767 raw reads that were assembled into 18,546 contigs. A BLAST search of the assembled contigs against non-redundant and Swiss-Prot databases showed that 6,463 contigs corresponded to BLASTx hits and indicated an interesting diversity of transcripts related to venom gene expression. The majority of these venom-related sequences code for a major polypeptide core, which comprises venom allergens, lethal-like proteins and esterases, and a minor peptide framework composed of inter-specific structurally conserved cysteine-rich toxins. Both the cDNA library and deep sequencing yielded large proportions of contigs that showed no similarities with known sequences. Conclusions To our knowledge, this is the first report of the venom gland transcriptome of the New World giant ant D. quadriceps. The glandular venom system was dissected, and the toxin arsenal was revealed; this process brought to light novel sequences that included an ICK-folded toxins, allergen proteins, esterases (phospholipases and carboxylesterases), and lethal-like toxins. These findings contribute to the understanding of the ecology, behavior and venomics of hymenopterans.
