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.

Gamma irradiation promotes chemo-sensitization potential of gallic acid through attenuation of autophagic flux to trigger apoptosis in an NRF2 inactivation signalling pathway. Free Radic Biol Med 2020; 160:111-124. [PMID: 32755671 DOI: 10.1016/j.freeradbiomed.2020.06.022] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2020] [Revised: 05/25/2020] [Accepted: 06/08/2020] [Indexed: 12/21/2022]
Abstract
Ionizing radiation has the potential to cause structural modification or change in electrochemical properties in parent lead pharmacophores that exhibit enhanced bioactivity. Gallic acid (GA), a triphenolic compound has displayed potent anticancer drug potency due to its withstanding antioxidant propensity. This study uncovered the comparative efficacy of gamma-irradiated gallic acid (GAIR) in the modulation of an antioxidant system for regulation apoptosis and autophagy. GAIR exhibited remarkable anti-proliferative efficacy as shown by MTT, clonogenic survival, and scratch assay. In addition to this, GAIR promoted intrinsic apoptosis through mitochondrial superoxide generation. GAIR decreased the activity of antioxidant enzymes by downregulating nuclear factor erythroid 2-related factor 2 (NRF2) and its downstream effector molecules NAD(P)H Quinone Dehydrogenase 1 (NQO1) and gamma-glutamylcysteine synthetase (GCLC). Simultaneously, GAIR attenuated autophagosome-lysosome fusion without altering the lysosomal activity. Inhibition of autophagic flux resulted in the accumulation of lipid droplets (LDs) such as hexadecanoic acid and oleic acid that fuelled superoxide generation leading to apoptosis. In the meantime, under oxidative upset, conversion of LDs to free fatty acids reduced leading to inhibition of ATP generation that subsequently provoked apoptosis. The effects of autophagy inhibition by GAIR on the therapeutic efficacy of chemotherapeutic drugs was studied and the co-treatment markedly decreased the cell viability and increased apoptosis. Further, GAIR exhibited potent antitumor activity in Dalton's Lymphoma-tumor bearing mice through modulation of apoptosis and autophagy without toxic activity. In conclusion, change in electrochemical properties by gamma radiation enhances the anticancer efficacy of gallic acid through superoxide mediated apoptosis fuelled by inhibition of lipophagy in an NRF2 dependent signaling pathway.

Abstract
Plant lectins are non-immunoglobin in nature and bind to the carbohydrate moiety of the glycoconjugates without altering any of the recognized glycosyl ligands. Plant lectins have found applications as cancer biomarkers for recognizing the malignant tumor cells for the diagnosis and prognosis of cancer. Interestingly, plant lectins contribute to inducing cell death through autophagy and apoptosis, indicating their potential implication in cancer inhibitory mechanism. In the present review, anticancer activities of major plant lectins have been documented, with a detailed focus on the signaling circuit for the possible molecular targeted cancer therapy. In this context, several lectins have exhibited preclinical and clinical significance, driving toward therapeutic potential in cancer treatment. Moreover, several plant lectins induce immunomodulatory activities, and therefore, novel strategies have been established from preclinical and clinical investigations for the development of combinatorial treatment consisting of immunotherapy along with other anticancer therapies. Although the application of plant lectins in cancer is still in very preliminary stage, advanced high-throughput technology could pave the way for the development of lectin-based complimentary medicine for cancer treatment.

Abstract
Eutirucallin is a lectin isolated from the latex of Euphorbia tirucalli, a plant known for its medical properties. The present study explores various characteristics of Eutirucallin including stability, cytotoxicity against tumor cells, antimicrobial and antiparasitic activities. Eutirucallin was stable from 2 to 40 days at 4°C, maintained hemagglutinating activity within a restricted range, and showed optimal activity at pH 7.0–8.0. Eutirucallin presented antiproliferative activity for HeLa, PC3, MDA-MB-231, and MCF-7 tumor cells but was not cytotoxic for non-tumorigenic cells such as macrophages and fibroblasts. Eutirucallin inhibited the Ehrlich ascites carcinoma in vivo and it was also observed that Eutirucallin inhibited 62.5% of Escherichia coli growth. Also, Eutirucallin showed to be effective when tested directly against Toxoplasma gondii infection in vitro. Therefore, this study sheds perspectives for pharmacological applications of Eutirucallin.

Abstract
To explore the cytotoxic mechanism of abrin P2 on human colon cancer HCT-8 cells, abrin P2 was isolated from the seed of Abrus precatorius L. It was found that abrin P2 exhibited cytotoxicity toward 12 different human cancer cell lines. Our results demonstrated that abrin P2 suppressed the proliferation of human colon cancer cells (HCT-8 cells) and induced cell cycle arrest at the S and G2/M phases. The mechanism by which abrin P2 inhibited cell proliferation was via the down-regulation of cyclin B1, proliferating cell nuclear antigen and Ki67, as well as the up-regulation of P21. In addition, abrin P2 induced a dose- and time-dependent increase in the rate of HCT-8 cell apoptosis. Treatment with both Z-VAD-FMK, a broad-spectrum caspase inhibitor, and abrin P2 demonstrated that abrin P2 induced HCT-8 cell apoptosis via the activation of caspases. Together, our results revealed that abrin P2-induced apoptosis in HCT-8 cells was associated with the activation of caspases-3/-8/-9, the reduction in the Bcl-2/Bax ratio, the loss of mitochondrial membrane potential, and the increase in cytochrome c release. We further showed that abrin P2 administration effectively suppressed the growth of colon cancer xenografts in nude mice. This is the first report that abrin P2 effectively inhibits colon cancer cell growth in vivo and in vitro by suppressing proliferation and inducing apoptosis.

Antitumor effect of soybean lectin mediated through reactive oxygen species-dependent pathway. Life Sci 2014; 111:27-35.

Abstract
AIMS The present study evaluated the potential role of soybean lectin's (SBL) anticancer effect in vitro in different cancer cell lines and the therapeutic effectiveness in vivo in Dalton's lymphoma (DL) bearing mice model. MAIN METHODS The effect of SBL on cell growth and viability was measured using MTT assay in different cancer cells in vitro. Apoptosis, autophagic cell death, DNA-damaging potential and reactive oxygen species (ROS) were analyzed in HeLa cells. The in vivo efficacy of SBL was demonstrated in Dalton's lymphoma (DL) bearing mice. KEY FINDINGS SBL demonstrated clear, strong antiproliferative activity without affecting normal cells; however, heat denaturation of SBL diminished the antiproliferative efficacy of molecule as demonstrated by MTT assay. A sharp 74.51 ± 3.5% and 82.95 ± 5.8% inhibition of tumor cell proliferation in DL mice occurred when SBL was administered at a dosage of 1 and 2mg/kg body weight (i.p.), respectively, for ten days with the induction of autophagic and apoptotic cell death. An in vitro investigation revealed that SBL-mediated autophagy, apoptosis and DNA damage in HeLa cells were inflicted through the generation of ROS in a dose-dependent manner. Interestingly, pre-treating HeLa cells with N-acetylcysteine (NAC), a typical ROS scavenger, led to a noticeable reduction in SBL-induced autophagy, apoptosis and DNA-damaging activities, suggesting that SBL's antitumor potential was governed by ROS activation. SIGNIFICANCE In this study, we evaluated the apoptotic, autophagic death, and DNA-damaging effects of SBL in cancer cells, which may have the potential to be used as a phyto-derived protein for cancer therapy.

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
In vitro immunostimulatory effect of Abrus lectins derived peptide fractions (AGP and ABP) was investigated in DL bearing mice. Both AGP and ABP were found to activate splenocytes and induced production of cytokines like IL-2, IFN-gamma and TNF-alpha indicating a Th1 type of immune response. Analysis of in vitro treated splenocytes by flow cytometry revealed an increase in percentage of T and B cell with high expression of activation markers (CD25(+) and CD71(+)). At the same time, expression of co-stimulatory markers was significantly high compared to tumor control. The tumor associated macrophages were able to stimulate NO production, IL-1 secretion, increased phagocytosis and decreased expression of mannose receptor. It was also observed that NK cell was activated by AGP and ABP. These results suggest that both AGP and ABP act as immunostimulants in vitro in DL bearing mice.

Abstract
In our previous study, Abrus abrin derived peptide fraction (ABP) with molecular weight in range of 600-1500Da was shown to have potent antitumor activity in Dalton's lymphoma (DL) tumor bearing mice. The purpose of this study was to elucidate the mechanism of mitochondrial apoptosis induced by the peptide fraction. ABP was found to have selective antiproliferative activity (10ng-100ng/ml) on several tumor cell lines in vitro without having any cytotoxic effect on normal cell lines with a dose of 1000ng/ml. Analysis of the growth inhibitory mechanism in HeLa cells revealed DNA fragmentation with appearance of the sub G(0)/G(1) peak indicative of apoptosis. Further investigation results showed that the apoptotic machinery of HeLa induced by ABP was associated with the release of reactive oxygen species, a drop in mitochondrial transmembrane potential, upregulation of Bax, downregulation of Bcl-2, and activation of caspase-3. The peptide fraction was found to target mitochondria of HeLa cells as observed by confocal microscopy. This peptide fraction offers a source of mitochondria penetrating peptides which might have therapeutic induction of apoptosis in cancer cells.
