Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Abrus precatorius L. (AP) is a folk medicine with a long-term medicinal history worldwide, which is extensively applied to various ailments, such as bronchitis, jaundice, hepatitis, contraception, tumor, abortion, malaria, etc. Meanwhile, its leaves are also served as tea in China, and its roots are employed as a substitute for Glycyrrhiza uralensis or as a raw material for the extraction of glycyrrhizin in India. Thus, AP is considered to be a plant with dual values of medicine and economy as well as its chemical composition and biological activity, which are of growing interest to the scientific community. AIM OF REVIEW In the review, the traditional application, botany, chemical constituents, pharmacological activities, and toxicity are comprehensively and systematically summarized. MATERIALS AND METHODS An extensive database retrieval was conducted to gather the specific information about AP from 1871 to 2022 using online bibliographic databases Web of Science, PubMed, SciFinder, Google Scholar, CNKI, and Baidu Scholar. The search terms comprise the keywords "Abrus precatorius", "phytochemistry", "pharmacological activity", "toxicity" and "traditional application" as a combination. RESULTS To date, AP is traditionally used to treat various diseases, including sore throat, cough, bronchitis, jaundice, hepatitis, abdominal pain, contraception, tumor, abortion, malaria, and so on. More than 166 chemical compounds have been identified from AP, which primarily cover flavonoids, phenolics, terpenoids, steroids, alkaloids, organic acids, esters, proteins, polysaccharides, and so on. A wide range of in vitro and in vivo pharmacological functions of AP have been reported, such as antitumor, antimicrobial, insecticidal, antiprotozoal, antiparasitic, anti-inflammatory, antioxidant, immunomodulatory, antifertility, antidiabetic, other pharmacological activities. The crushed seeds in powder or paste form were comparatively toxic to humans and animals by oral administration. Interestingly, the methanolic extracts were non-toxic to adult Wistar albino rats at various doses (200 and 400 mg/kg) daily. CONCLUSIONS The review focuses on the traditional application, botany, phytochemistry, pharmacological activities, and toxicity of AP, which offers a valuable context for researchers on the current research status and a reference for further research and applications of this medicinal plant.

Effect of chrysophanic acid on immune response and immune genes transcriptomic profile in Catla catla against Aeromonas hydrophila. Sci Rep 2021; 11:612. [PMID: 33436677 PMCID: PMC7804155 DOI: 10.1038/s41598-020-79629-9] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2020] [Accepted: 12/07/2020] [Indexed: 01/29/2023] Open
Abstract
The effect of chrysophanic acid (CA) (2, 4, and 8 mg kg-1) on the immunity and immune-related gene profile of Catla catla against Aeromonas hydrophila is reported. In both control and treated groups fed with 2 mg kg-1 (2 CA), the phagocytosis, hemolytic, myeloperoxidase content, and superoxide anion production decreased significantly between 6th and 8th weeks, whereas when fed with 4 mg kg-1 CA (4 CA) the H2O2 production and nitric oxide synthase increased significantly between 4th and 8th week. When fed with 2 CA and 4 CA diets, the total protein, bactericidal, and antibody titer increased significantly from the 4th week onwards. When fed with 2 CA, the IL-1β and IL-10 mRNA expression of head kidney leucocytes were significant between weeks 6 and 8. The expressions of toll-like receptors significantly increased when fed with a 4 CA diet from 4th week onwards. The 4 CA group significantly increased in TNF-α, TNF receptor-associated factor 6 (NOD), which influences protein expression, after the 4th week. The mRNA transcription of MHCI, lysozyme-chicken and goose type expressions significantly increased in 4 CA group within the 4th week. In summary, the dietary administration of 4 mg kg-1 of CA (4 CA) provides better immunity and enhances the up-regulation of immune-related genes in Catla against A. hydrophila.

Abstract
Abrus agglutinin (AGG), a plant lectin isolated from the seeds of Abrus precatorius, has documented antitumor and immunostimulatory effects in murine models. To examine possible antitumor activity against breast cancer, we established human breast tumor xenografts in athymic nude mice and intraperitoneally administered AGG. AGG inhibited tumor growth and angiogenesis as confirmed by monitoring the expression of Ki-67 and CD-31, respectively. In addition, TUNEL positive cells increased in breast tumors treated with AGG suggesting that AGG mediates anti-tumorigenic activity through induction of apoptosis and inhibition of angiogenesis. On a molecular level, AGG caused extrinsic apoptosis through ROS generation that was AKT-dependent in breast cancer cells, without affecting primary mammary epithelial cells, suggesting potential cancer specificity of this natural compound. In addition, using HUVECs, AGG inhibited expression of the pro-angiogenic factor IGFBP-2 in an AKT-dependent manner, reducing angiogenic phenotypes both in vitro and in vivo. Overall, the present results establish that AGG promotes both apoptosis and anti-angiogenic activities in human breast tumor cells, which might be exploited for treatment of breast and other cancers.

Abstract
Background: Abrus precatorius seeds traditionally used for the treatment of sciatica and alopecia contains the toxic protein, abrin, a Type II Ribosome Inactivating Protein. Ayurveda recommends the use of Abrus seeds after the Shodhana process (detoxification). Objective: The current study was aimed at performing the Shodhana process, swedana (boiling) of Abrus precatorius seeds using water as a medium and to evaluate the anti-inflammatory potential of seed extract post detoxification. Materials and Methods: Non-detoxified and detoxified extracts were prepared and subsequently subjected to various in vitro and in vivo assays. In hemagglutination assay, the non-detoxified extract shows higher agglutination of RBCs than detoxified extract indicating riddance of toxic hemagglutinating proteins by Shodhana. This was confirmed by the SDSPAGE analysis of detoxified extract revealing the absence of abrin band in detoxified extract when compared to non-detoxified extract. Results: The cytotoxicity assay in HeLa cell line expresses a higher reduction in growth percentage of the cells with non-detoxified extract as compared to detoxified extract indicating successful detoxification. Brine shrimp lethality test indicated the reduction in toxicity index of detoxified extract as compared to non-detoxified extract. Further, the whole body apoptosis assay in zebrafish revealed that percentage of viable cells were greater for detoxified extract than non-detoxified extract. The anti-inflammatory studies using carrageenan induced paw edema model in rats was carried out on the extracts with doses of 100 mg/kg and 200 mg/kg, per oral, where the detoxified extract exhibited significant inhibition of rat paw edema at both the doses comparable to that of Diclofenac sodium. Conclusion: Absence of toxicity and the retention of the anti-inflammatory activity of detoxified Abrus seed extract confirmed that the Swedana process is effective in carrying out the detoxification without affecting its therapeutic potential.

Abstract
AIM Abrus agglutinin (AGG) from the seeds of Indian medicinal plant Abrus precatorius belongs to the class II ribosome inactivating protein family. In this study we investigated the anticancer effects of AGG against human hepatocellular carcinoma in vitro and in vivo. METHODS Cell proliferation, DNA fragmentation, Annexin V binding, immunocytofluorescence, Western blotting, caspase activity assays and luciferase assays were performed to evaluate AGG in human liver cancer cells HepG2. Immunohistochemical staining and TUNEL expression were studied in tumor samples of HepG2-xenografted nude mice. RESULTS AGG induced apoptosis in HepG2 cells in a dose- and time-dependent manner. AGG-treated HepG2 cells demonstrated an increase in caspase 3/7, 8 and 9 activities and a sharp decrease in the Bcl-2/Bax ratio, indicating activation of a caspase cascade. Co-treatment of HepG2 cells with AGG and a caspase inhibitor or treatment of AGG in Bax knockout HepG2 cells decreased the caspase 3/7 activity in comparison to HepG2 cells exposed only to AGG. Moreover, AGG decreased the expression of Hsp90 and suppressed Akt phosphorylation and NF-κB expression in HepG2 cells. Finally, AGG treatment significantly reduced tumor growth in nude mice bearing HepG2 xenografts, increased TUNEL expression and decreased CD-31 and Ki-67 expression compared to levels observed in the untreated control mice bearing HepG2 cells. CONCLUSION AGG inhibits the growth and progression of HepG2 cells by inducing caspase-mediated cell death. The agglutinin could be an alternative natural remedy for the treatment of human hepatocellular carcinomas.

Abstract
The clinical and pharmacological activities of ginseng are known to modulate immune function, metabolic processes and neuro-endocrine system activities. Ginseng saponins are the principle active ingredients in the formation of immune stimulating complexes. The objective of this study was to evaluate the in vitro effect of ginseng total saponin (GTS) on the phagocytic capacity of canine peripheral blood phagocytes. GTS itself did not cause any direct effect on the phagocytic capacity of peripheral blood mononuclear cells (PBMC) and polymorphonuclear cells (PMN) but not peripheral blood monocytes. However, the phagocytic capacity of PMN and monocytes, but not PBMC, was enhanced by the culture supernatant from PBMC treated with GTS. The phagocytic capacity of PMN and monocytes was also increased by treatment with recombinant canine (rc) tumor necrosis factor (TNF)-α. The ability of the culture supernatant from GTS-treated PBMC to stimulate the phagocytic capacity of phagocytes was inhibited by addition of anti-rc TNF-α polyclonal antibody (pAb) prior to the culture. The amount of TNF-α in the culture supernatant from PBMC was shown to increase upon treatment of GTS as compared with that of vehicle-treated PBMC culture supernatant. These results suggest that GTS has an immunoenhancing effect on the phagocytic capacity of canine peripheral blood phagocytes, which is mainly mediated by TNF-α released from GTS-stimulated PBMC.

Abstract
Nowadays, toxicological studies are contributing to human health more than ever. Reports on the toxicological studies of plant proteins, which are continuously growing in number in the literature, have been reviewed. Two important aspects are discussed: dietary safety evaluation, including toxicity tests and the maximum daily intake allowance, and the appropriate proportion in our daily diets of proteins from traditional foods and of new proteins from plant sources not traditionally employed as foods. Water hyacinth leaf proteins, sweet lupin proteins and canola proteins have not been shown to be toxic, although they are not traditionally employed as food proteins. These findings are very important for exploiting valuable new protein sources that are suitable for human or animal consumption and applicable to the food industry. Acutely toxic proteins, including lectins, ribosome-inactivating proteins, inhibitors of proteolytic enzymes and glycohydro-lases, have been isolated from plant materials and identified. Their toxicities and molecular characteristics have been described. The toxicity of proteins depends upon their specific native structures. Once they are denatured by appropriate treatment, such as heating, their toxicity can be reduced or even eliminated. These findings indicate that raw materials that contain this kind of toxic protein are not edible. However, after proper processing, they may be suitable for human or animal consumption. Although the toxicities of type 2 ribosome-inactivating proteins reported by different authors vary, the maximum dosages are still trace amounts.

Abstract
Abrin (ABR), a protein purified from the seeds of Abrus precatorius, induces apoptosis in various types of cancer cells. However, the detailed mechanism remains largely uncharacterized. By using a cDNA microarray platform, we determined that prohibitin (PHB), a tumor suppressor protein, is significantly upregulated in ABR-triggered apoptosis. ABR-induced upregulation of PHB is mediated by the stress-activated protein kinase/c-Jun NH2-terminal kinase (SAPK/JNK) pathway, as demonstrated by chemical inhibitors. In addition, ABR significantly induced the expression of Bax as well as the activation of caspase-3 and poly(ADP-ribose) polymerase (PARP) in Jurkat T cells, whereas the reduction of PHB by specific RNA interference delayed ABR-triggered apoptosis through the proapoptotic genes examined. Moreover, our results also indicated that nuclear translocation of the PHB-p53 complex may play a role in the transcription of Bax. Collectively, our data show that PHB plays a role in ABR-induced apoptosis, which may be helpful for the development of diagnostic or therapeutic agents.

Abstract
Abrus agglutinin (AAG), a hetero tetrameric gal beta (1-3) NAc gal specific lectin, is isolated from seeds of Abrus precatorius. In our previous studies we found that the protein could act as an immunomodulator and immunoadjuvant in native (NA) and heat denatured (HDA) conditions. An anticancer effect of the lectin is reported, but its mode of action is not clearly known. In the present study, the anti-tumor activity of AAG (NA, HDA) has been evaluated in a murine Dalton's lymphoma (DL) ascites tumorogenic model. We found that treatment with both NA and HDA were able to decrease the tumor cell number in vivo and significantly increased median survival time. In vitro studies showed that AAG (NA, HDA) treatment of Dalton's lymphoma ascites cells (DLAC) resulted in growth inhibition at the concentration of 1 microg/ml and above. Whereas, AAG (NA, HDA) at much lower concentrations (approximately 1 ng/ml) can stimulate peritoneal macrophage and spleen derived NK cells in vitro demonstrating cytotoxicity against DLAC. Cell cycle analysis showed an increased number of cells in Sub-G0/G1 phase for in vitro and in vivo treatments. In summary, AAG (NA, HDA) at non-toxic concentration was able to elicit anti-tumor effects in DL bearing mice by stimulating the innate immune system and Th1 type immunomodulation.

Abstract
INTRODUCTION Castor and jequirity beans are uncommon causes of poisoning. The more common but less severe castor poisoning is well described, but jequirity bean (Abrus Precatorius) poisoning is rare. The toxicity is attributed to toxalbumins (ricin and abrin) that act by inhibiting protein synthesis. Their use as agents of biological warfare, mechanisms of action, and clinical features of poisoning are summarized. CASE REPORT A 30-year-old previously healthy female presented with bloody diarrhea and deep coma following ingestion of 3-4 seeds of a plant called 'ratti.' Investigations, including an MRI brain scan, showed evidence of acute demyelinating encephalitis. The patient died three days later due to progressive central nervous system depression. DISCUSSION This is a previously unreported manifestation of jequirity bean poisoning. Demyelination is immune-mediated, and Abrus is a well-known immuno-modulator and stimulator. A possible immunological pathogenic mechanism is hypothesized.

Abstract
Ketamine is an intravenous anesthetic agent. Clinically, induction of anesthesia with ketamine can cause immunosuppression. Macrophages play important roles in host defense. In this study, we attempted to evaluate the effects of ketamine on macrophage functions and its possible mechanism using mouse macrophage-like Raw 264.7 cells as the experimental model. Exposure of macrophages to 10 and 100 microM ketamine, which correspond to 0.1 and 1 times the clinically relevant concentration, for 1, 6, and 24 h had no effect on cell viability or lactate dehydrogenase release. When the administered concentration reached 1000 microM, ketamine caused a release of lactate dehydrogenase and cell death. Ketamine, at 10 and 100 microM, did not affect the chemotactic activity of macrophages. Administration of 1000 microM ketamine in macrophages resulted in a decrease in cell migration. Treatment of macrophages with ketamine reduced phagocytic activities. The oxidative ability of macrophages was suppressed by ketamine. Treatment with lipopolysaccharide induced TNF-alpha, IL-1beta, and IL-6 mRNA in macrophages. Administration of ketamine alone did not influence TNF-alpha, IL-1beta, or IL-6 mRNA production. Meanwhile, cotreatment with ketamine and lipopolysaccharide significantly inhibited lipopolysaccharide-induced TNF-alpha, IL-1beta, and IL-6 mRNA levels. Exposure to ketamine led to a decrease in the mitochondrial membrane potential. However, the activity of mitochondrial complex I NADH dehydrogenase was not affected by ketamine. This study shows that a clinically relevant concentration of ketamine (100 microM) can suppress macrophage function of phagocytosis, its oxidative ability, and inflammatory cytokine production possibly via reduction of the mitochondrial membrane potential instead of direct cellular toxicity.

Abstract
Lectins are known as polyclonal activators of lymphocytes and work through the induction of battery of cytokines, which vary from lectin to lectin. Most widely used biological response modifier Mistletoe lectin (ML-1) in therapy stimulates lymphocytes, macrophages, and natural killer cells and induces both TH1 and TH2 type cytokines. Abrus agglutinin, similar to ML-1 with respect to carbohydrate specificity [gal (beta1-->3) gal/Nac], was studied both in native (NA) and heat denatured (HDA) condition for murine splenocyte proliferation, cytokine secretion, NK-cell activation, and thymocyte proliferation in vitro with a view to assess its potential as an immunomodulator. Both NA and HDA activate splenocytes and induce production of cytokines like IL-2, IFN-gamma and TNF-alphabeta indicating a TH1 type of immune response. Native agglutinin and HDA induced conditioned media of adherent splenocytes could stimulate non-adherent splenocytes and vice versa. Heat denatured agglutinin was able to induce NK-cell activation at much lower concentration than that of NA, but the extent of NK-cell activation was higher for NA. Proliferation of thymocytes by NA and HDA was also observed. This study indicates that Abrus agglutinin could be a potential immunomodulator both in native as well as in heat denatured form.

Abstract
Many bioactive peptides are in therapeutic use as immunomodulators at present. The origin of these bioactive peptides is diverse. Such bioactive peptides are reported to be present in enzymatic digest of food and milk proteins. In our previous work we have reported that Abrus agglutinin retains its bioactivity even after heat denaturation but loses its haemagglutination properties. This leads to the supposition that immunostimulatory regions in the protein might be responsible for its in vivo and in vitro stimulatory properties. Thus the bioactivity of tryptic digest of Abrus agglutinin (TDA) was checked in vitro to ascertain the presence of some bioactive region in the protein, which will lead to the discovery of certain immunostimulatory peptides which might be of use in nonspecific immunotherapy. In this study it is observed that TDA stimulates macrophage increasing the phagocytic and bactericidal activity as well as hydrogen peroxide production. TDA also proliferates splenocytes leading to Th1 response and NK cell activation.
