Abstract
Ribosome-inactivating proteins (RIPs) are toxic proteins with N-glycosidase activity. RIPs exert their action by removing a specific purine from 28S rRNA, thereby, irreversibly inhibiting the process of protein synthesis. RIPs can target both prokaryotic and eukaryotic cells. In bacteria, the production of RIPs aid in the process of pathogenesis whereas, in plants, the production of these toxins has been attributed to bolster defense against insects, viral, bacterial and fungal pathogens. In recent years, RIPs have been engineered to target a particular cell type, this has fueled various experiments testing the potential role of RIPs in many biomedical applications like anti-viral and anti-tumor therapies in animals as well as anti-pest agents in engineered plants. In this review, we present a comprehensive study of various RIPs, their mode of action, their significance in various fields involving plants and animals. Their potential as treatment options for plant infections and animal diseases is also discussed.

Cucurbitacins as potential anticancer agents: new insights on molecular mechanisms. J Transl Med 2022; 20:630. [PMID: 36585670 PMCID: PMC9805216 DOI: 10.1186/s12967-022-03828-3] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2022] [Accepted: 12/11/2022] [Indexed: 01/01/2023] Open
Abstract
Since ancient times, plants have been an extensive reservoir of bioactive compounds with therapeutic interest for new drug development and clinical application. Cucurbitacins are a compelling example of these drug leads, primarily present in the plant kingdom, especially in the Cucurbitaceae family. However, these natural compounds are also known in several genera within other plant families. Beyond the Cucurbitaceae family, they are also present in other plant families, as well as in some fungi and one shell-less marine mollusc. Despite the natural abundance of cucurbitacins in different natural species, their obtaining and isolation is limited, as a result, an increase in their chemical synthesis has been developed by researchers. Data on cucurbitacins and their anticancer activities were collected from databases such as PubMed/MedLine, TRIP database, Web of Science, Google Scholar, and ScienceDirect and the information was arranged sequentially for a better understanding of the antitumor potential. The results of the studies showed that cucurbitacins have significant biological activities, such as anti-inflammatory, antioxidant, antimalarial, antimicrobial, hepatoprotective and antitumor potential. In conclusion, there are several studies, both in vitro and in vivo reporting this important anticancer/chemopreventive potential; hence a comprehensive review on this topic is recommended for future clinical research.

Abstract
Oxidative stress is the imbalance between reactive oxygen species (ROS) production, and accumulation and the ability of a biological system to clear these reactive products. This imbalance leads to cell and tissue damage causing several disorders in human body, such as neurodegeneration, metabolic problems, cardiovascular diseases, and cancer. Cucurbitaceae family consists of about 100 genera and 1,000 species of plants including mostly tropical, annual or perennial, monoecious, and dioecious herbs. The plants from Cucurbita species are rich sources of phytochemicals and act as a rich source of antioxidants. The most important phytochemicals present in the cucurbits are cucurbitacins, saponins, carotenoids, phytosterols, and polyphenols. These bioactive phyto-constituents are responsible for the pharmacological effects including antioxidant, antitumor, antidiabetic, hepatoprotective, antimicrobial, anti-obesity, diuretic, anti-ulcer activity, and antigenotoxic. A wide number of in vitro and in vivo studies have ascribed these health-promoting effects of Cucurbita genus. Results of clinical trials suggest that Cucurbita provides health benefits for diabetic patients, patients with benign prostate hyperplasia, infertile women, postmenopausal women, and stress urinary incontinence in women. The intend of the present review is to focus on the protective role of Cucurbita spp. phytochemicals on oxidative stress-related disorders on the basis of preclinical and human studies. The review will also give insights on the in vitro and in vivo antioxidant potential of the Cucurbitaceae family as a whole.

Abstract
Immunotoxins are Ab‐cytotoxin chimeric molecules with mighty cytotoxicity. Programmed cell death 1‐ligand 1 (PD‐L1), is a transmembrane protein expressed mainly in inflammatory tumor tissues and plays a pivotal role in immune escape and tumor progression. Although PD‐L1 immune checkpoint therapy has been successful in some cases, many patients have not benefited enough due to primary/secondary resistance. In order to optimize the therapeutic efficacy of anti‐PD‐L1 mAb, we used durvalumab as the payload and CUS245C, a type I ribosome‐inactivating protein isolated from Cucurbita moschata, as the toxin moiety, to construct PD‐L1‐specific immunotoxin (named D‐CUS245C) through the engineered cysteine residue. In vitro, D‐CUS245C selectively killed PD‐L1+ tumor cells. In vivo studies also showed that D‐CUS245C had obvious antitumor effect on PD‐L1+ human xenograft tumors in nude mice. In conclusion, in the combination of the toxin with mAb, this study developed a new immunotoxin targeting PD‐L1, emphasizing a novel and promising treatment strategy and providing a valuable way to optimize cancer immunotherapy.

Abstract
Epidermal growth factor receptor (EGFR) overexpression is related to the increased aggressiveness, metastases, and poor prognosis in various cancers. In this study, we successfully constructed a new EGFR nanobody-based immunotoxin rE/CUS containing cucurmosin (CUS), The immunotoxin was expressed by prokaryotic system and we obtained a yield of 5 mg protein per liter expression medium. The percentage of it's binding ability totumor cell lines A549, HepG2, SW116, which highly expressed EGFR was 55.6%, 79.6% and 97.1%, respectively, but SW620 was only 4.45%. rE/CUS has the ability to bind A549, HepG2, SW116 cells specifically, and the antigen binding capability was not affected because of extra part of CUS component. The rE/CUS significantly inhibited the cell viability against EGFR over expression tumor cell lines in a dose-and time-dependent manner. Moreover, rE/CUS also induced apoptosis of HepG2 and A549 mightily. Our results demonstrate that rE/CUS is a potential therapeutic strategy for treating EGFR-positive solid tumors.

Abstract
Ribosome Inactivating Proteins (RIPs) are rRNA N-glycosidases that inhibit protein synthesis through the elimination of a single adenine residue from 28S rRNA. Many of these toxins have been characterized in depth from a biochemical and molecular point of view. In addition, their potential use in medicine as highly selective toxins is being explored. In contrast, the evolutionary history of RIP encoding genes has remained traditionally underexplored. In recent years, accumulation of large genomic data has fueled research on this issue and revealed unexpected information about the origin and evolution of RIP toxins. In this review we summarize the current evidence available on the occurrence of different evolutionary mechanisms (gene duplication and losses, horizontal gene transfer, synthesis de novo and domain combination) involved in the evolution of the RIP gene family. Finally, we propose a revised nomenclature for RIP genes based on their evolutionary history.

Abstract
Ribosome-inactivating proteins (RIPs) are enzymes which depurinate ribosomal RNA (rRNA), thus impeding the process of translation resulting in inhibition of protein synthesis. They are produced by various organisms including plants, fungi and bacteria. RIPs from plants are linked to plant defense due to their antiviral, antifungal, antibacterial, and insecticidal activities in which they can be applied in agriculture to combat microbial pathogens and pests. Their anticancer, antiviral, embryotoxic, and abortifacient properties may find medicinal applications. Besides, conjugation of RIPs with antibodies or other carriers to form immunotoxins has been found useful to research in neuroscience and anticancer therapy.

[PMID: 29124196 PMCID: PMC5668913 DOI: 10.1016/j.bbrep.2015.09.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2015] [Revised: 09/04/2015] [Accepted: 09/09/2015] [Indexed: 01/15/2023] Open
Abstract
The type 1 ribosome inactivating protein from Momordica balsamina (MbRIP1) has been shown to interact with purine bases, adenine and guanine of RNA/DNA. We report here the binding and structural studies of MbRIP1 with a pyrimidine base, cytosine; cytosine containing nucleoside, cytidine; and cytosine containing nucleotide, cytidine diphosphate. All three compounds bound to MbRIP1 at the active site with dissociation constants of 10−4 M–10−7 M. As reported earlier, in the structure of native MbRIP1, there are 10 water molecules in the substrate binding site. Upon binding of cytosine to MbRIP1, four water molecules were dislodged from the substrate binding site while five water molecules were dislodged when cytidine bound to MbRIP1. Seven water molecules were dislocated when cytidine diphosphate bound to MbRIP1. This showed that cytidine diphosphate occupied a larger space in the substrate binding site enhancing the buried surface area thus making it a relatively better inhibitor of MbRIP1 as compared to cytosine and cytidine. The key residues involved in the recognition of cytosine, cytidine and cytidine diphosphate were Ile71, Glu85, Tyr111 and Arg163. The orientation of cytosine in the cleft is different from that of adenine or guanine indicating a notable difference in the modes of binding of purine and pyrimidine bases. Since adenine containing nucleosides/nucleotides are suitable substrates, the cytosine containing nucleosides/nucleotides may act as inhibitors. The binding and structural studies of MbRIP1 with cytosine and cytosine containing nucleoside and nucleotide. The optimum element for specificity in cytosine containing sequences of RNA structures is a nucleoside moiety. CDP interact the most with the residues of the binding site of MbRIP1 which indicates that it has the maximum binding affinity. Cytosine containing site may provide protection to RNAs from RIP1 type toxins.

Abstract
Ribosome-inactivating proteins (RIPs) belong to a family of enzymes that attack eukaryotic ribosomes and potently inhibit cellular protein synthesis. RIPs possess several biomedical properties, including anti-viral and anti-tumor activities. Multiple RIPs are known to inhibit tumor cell proliferation through inducing apoptosis in a variety of cancers, such as breast cancer, leukemia/lymphoma, and hepatoma. This review focuses on the anti-tumor activities of RIPs and their apoptotic effects through three closely related pathways: mitochondrial, death receptor, and endoplasmic reticulum pathways.

Abstract
Ribosome-inactivating proteins (RIPs) are toxins that act as N-glycosidases (EC 3.2.2.22). They are mainly produced by plants and classified as type 1 RIPs and type 2 RIPs. There are also RIPs and RIP related proteins that cannot be grouped into the classical type 1 and type 2 RIPs because of their different sizes, structures or functions. In addition, there is still not a uniform nomenclature or classification existing for RIPs. In this review, we give the current status of all known plant RIPs and we make a suggestion about how to unify those RIPs and RIP related proteins that cannot be classified as type 1 or type 2 RIPs.

PANC-1 pancreatic cancer cell growth inhibited by cucurmosin alone and in combination with an epidermal growth factor receptor-targeted drug. Pancreas 2014; 43:291-7.

Abstract
OBJECTIVES To investigate the inhibition of PANC-1 pancreatic cancer cell growth by cucurmosin (CUS) and its possible mechanism. METHODS We observed the inhibition of PANC-1 cell growth by sulforhodamine B and colony-forming experiments in vitro and established nonobese diabetic/severe combined immunodeficiency mouse subcutaneous tumor models in vivo. We used Western blot to analyze protein levels related to apoptosis and epidermal growth factor receptor (EGFR) signaling pathways after drug intervention, whereas the messenger RNA expression of EGFR was analyzed by quantitative real-time polymerase chain reaction. RESULTS Sulforhodamine B and colony-forming experiments indicated that CUS inhibited PANC-1 cell proliferation in a dose- and time-dependent manner. A stronger inhibitory effect was observed when CUS was combined with gefitinib. The subcutaneous tumor growth was also inhibited. Western blot showed that all the examined proteins decreased, except for 4E-BP1 and the active fragments of caspase 3 and caspase 9 increased. Epidermal growth factor receptor expression did not change significantly in quantitative real-time polymerase chain reaction. CONCLUSIONS Cucurmosin can strongly inhibit the growth of PANC-1 cells in vitro and in vivo. Cucurmosin can down-regulate EGFR protein expression, but not at the messenger RNA level. Cucurmosin can also inhibit the ras/raf and phosphatidylinositol 3-kinase/Akt downstream signaling pathways and enhance the sensitivity of the EGFR-targeted drug gefitinib.

Abstract
The ribosome inactivating proteins (RIPs) of type 1 are plant toxins that eliminate adenine base selectively from the single stranded loop of rRNA. We report six crystal structures, type 1 RIP from Momordica balsamina (A), three in complexed states with ribose (B), guanine (C) and adenine (D) and two structures of MbRIP-1 when crystallized with adenosine triphosphate (ATP) (E) and 2'-deoxyadenosine triphosphate (2'-dATP) (F). These were determined at 1.67Å, 1.60Å, 2.20Å, 1.70Å, 2.07Å and 1.90Å resolutions respectively. The structures contained, (A) unbound protein molecule, (B) one protein molecule and one ribose sugar, (C) one protein molecule and one guanine base, (D) one protein molecule and one adenine base, (E) one protein molecule and one ATP-product adenine molecule and (F) one protein molecule and one 2'-dATP-product adenine molecule. Three distinct conformations of the side chain of Tyr70 were observed with (i) χ(1)=-66°and χ(2)=165° in structures (A) and (B); (ii) χ(1)=-95° and χ(2)=70° in structures (C), (D) and (E); and (iii) χ(1)=-163° and χ(2)=87° in structure (F). The conformation of Tyr70 in (F) corresponds to the structure of a conformational intermediate. This is the first structure which demonstrates that the slow conversion of DNA substrates by RIPs can be trapped during crystallization.
