Toxicon 2024; 244:107773. [PMID: 38795848 DOI: 10.1016/j.toxicon.2024.107773] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2024] [Revised: 05/02/2024] [Accepted: 05/20/2024] [Indexed: 05/28/2024]
Abstract
Sophora flavescens Aiton, a traditional Chinese medicine that was supposed to predominantly play an anti-inflammatory role, has been used to treat multiple diseases, including cancer, for over two thousand years. Recently, it has attracted increasing attention due to the anti-tumor properties of Oxymatrine, one of the most active alkaloids extracted from S. flavescens. This study aims to explore it's anti-tumor effects in non-small cell lung cancer (NSCLC) and the underlying mechanisms. We first investigated the effects of oxymatrine on cell apoptosis in lung cancer cell lines A549 and PC9 as well as explored related genes in regulating the apoptosis by transcriptome analysis. Subsequently, to further study the role of TRIM46, we constructed two types of TRIM46 over-expression cells (A549TRIM46+ and PC9TRIM46+ cells) and then investigated the effect of TRIM46 on oxymatrine-induced apoptosis. Moreover, we explored the effect of TRIM46 on downstream signaling pathways. Transcriptome analysis suggested that shared differentially expressed genes (DEGs) in A549 and PC9 cells treated with oxymatrine were CACNA1I, PADI2, and TRIM46. According to TCGA database analysis, the abundance of TRIM46 expression was higher than CACNA1I, and PADI2 in lung cancer tissues, then was selected as the final DEG for subsequent studies. We observed that oxymatrine resulted in down-expression of TRIM46 as well as induced the apoptosis of the cancer cells in a dose- and time-dependent manner. Meanwhile, we found that apoptosis induced by oxymatrine was inhibited by over-expressing TRIM46. Furthermore, our study indicated that the NF-κB signaling pathway was involved in apoptosis suppressed by TRIM46. We conclude that TRIM46 is the direct target of oxymatrine to induce anti-tumor apoptosis and may activate the downstream NF-κB signaling pathway.

Oxymatrine alleviates high-fat diet/streptozotocin-induced non-alcoholic fatty liver disease in C57BL/6 J mice by modulating oxidative stress, inflammation and fibrosis. Biomed Pharmacother 2024; 174:116491. [PMID: 38537582 DOI: 10.1016/j.biopha.2024.116491] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 03/12/2024] [Accepted: 03/19/2024] [Indexed: 05/01/2024] Open
Abstract
Non-alcoholic fatty liver disease (NAFLD) represents a complex complication of type 2 diabetes mellitus (T2DM). Oxymatrine (OMT) is an alkaloid extracted from Sophora flavescens with broad pharmacological effects. However, there is currently a lack of research on OMT in the field of NAFLD. The present study aimed to explore the effects and underlying mechanisms of oxymatrine in treating T2DM with NAFLD. The T2DM mice model was induced by high-fat diet (HFD) combined with streptozotocin (STZ) injection in male C57BL/6 J mice. Animals were randomly divided into four groups (n = 8): Control group, DC group, OMT-L group (45 mg/kg i.g.), and OMT-H group (90 mg/kg, i.g.). The drug was administered once a day for 8 weeks. In addition, HepG2 hepatocytes were incubated with palmitic acid (PA) to establish a fatty liver cell model. Treated with OMT, the body weight and fasting blood glucose (FBG) of DC mice were reduced and the liver organ coefficient was significantly optimized. Meanwhile, OMT markedly enhanced the activities of key antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px), and also reduced malondialdehyde (MDA) levels. These biochemical alterations were accompanied by noticeable improvements in liver histopathology. Furthermore, OMT down-regulated the expression of NOD-like receptor protein 3 (NLRP3), interleukin-1β (IL-1β), transforming growth factor-β1 (TGF-β1) and collagen I significantly, highlighting its potential in modulating inflammatory and fibrotic pathways. In conclusion, OMT improved liver impairment effectively in diabetic mice by suppressing oxidative stress, inflammation and fibrosis. These results suggest that OMT may represent a novel therapy for NAFLD with diabetes.

Abstract
Cryopreservation (CP) enables pooling and long-term banking of various types of cells, which is indispensable for the cell therapeutics. Dimethyl sulfoxide (DMSO) is universally used as a cryoprotectant in basic and clinical research. Although, the use of DMSO has been under serious debate due to significant clinical side effects correlated with infusions of cellular therapy products containing DMSO, the effect of CP with DMSO on the cell properties and functions remains unknown. Here, we experimentally found that the CP of human bone mesenchymal stem cells (hBMSCs) with 10 % DMSO results 10-15 % of cells apoptosis upon immediate freeze-thaw, ca. 3.8 times of DNA damage/repair relative to the fresh ones after post-thaw cultured in 48 h, and cell cycle arrests at G0/G1 after post-thaw cultured in 24 h. Moreover, CP with 10 % DMSO significantly increases the reactive oxygen species (ROS) level of the frozen-thawed MSCs which may be one of the causes impair cellular properties and functions. Indeed, we found that the differentiation and migration ability of post-thaw cultured hBMSCs decrease as the expression of adipogenic, osteogenic genes and F-actin reduces in the comparison with those of the fresh cells.

Abstract
Oxymatrine is a quinolizidine alkaloid mainly derived from Kushen; it possesses various therapeutic effects, such as organ- and tissue-protective, anticancer, and antiviral effects. The research directions for oxymatrine remain broad. In order to explore the overall status of oxymatrine-based research, we carried out a bibliometric analysis to summarize the oxymatrine-based, English-written studies published in the past 22 years. In total, 267 studies were included, most of which were original. The number of annual studies slowly increased with some fluctuations. Other than China, 11 different countries conducted studies on oxymatrine; the variety in the country of origin of these publications is presented as a recently increasing trend. Many affiliates and researchers have participated in oxymatrine-based research. Various treatment mechanisms involving different oxymatrine pathways have led to research in a wide range of fields, being published in numerous journals. Two particularly popular research fields related to oxymatrine involved anticancer and anti-inflammation. From this research, we concluded that with increasing and continuous in-depth studies, more therapeutic effects and mechanisms will be elucidated, and oxymatrine may present as a viable option for the treatment of additional diseases.

Abstract
Introduction. Oxymatrine is a natural quinazine alkaloid extracted from Sophora flavescens and has many medicinal values. Oxymatrine showed protective effects, viral inhibition and effects against lung cancer.Hypothesis/Gap Statement. Individuals with lung cancer exhibit heightened vulnerability to COVID-19 infection due to compromised immune function. In conjunction with COVID-19, it is hypothesized that oxymatrine may exert potent pharmacological effects on lung cancer patients.Aim. The objective of this study was to assess the pharmacological mechanisms and targets of oxymatrine in relation to COVID-19 lung cancer.Methodology. Utilizing network pharmacology analysis, a selection of 2628 genes were identified as co-targets for both COVID-19 and lung cancer. Subsequently, a clinicopathological analysis was conducted by integrating RNA-Seq and clinical data obtained from the TCGA-LUAD lung cancer dataset, which was acquired from the official TCGA website. The identification of pharmacological targets for oxymatrine was accomplished through the utilization of various databases including Pharm mapper, SWISS Target prediction, and STITCH. These identified targets were further investigated for protein-protein interaction (PPI) using STRING, as well as for gene ontology (GO) and KEGG pathways.Results. The effects of oxymatrine on COVID-19-induced lung cancer were mediated by immune regulation, cytoprotection, antiviral, and anti-inflammatory activities, immune regulation, and control of related signalling pathways, including the formation of the neutrophil extracellular trap, phagosome, Toll-like receptor signalling pathway, apoptosis, proteoglycans in cancer, extracellular matrix disassembly, and proteolysis involved in cellular protein catabolism. Furthermore, important substances and genes like ALB, MMP3, MMP1, and TLR4 may affect how oxymatrine suppresses lung cancer/COVID-19 development.Conclusion. To treat COVID-19 or lung cancer paired with COVID-19, oxymatrine may improve the therapeutic efficacy of current clinical antiviral medicines and immunotherapy.

Protective effect of Platycodon grandiflorus polysaccharide on apoptosis and mitochondrial damage induced by pseudorabies virus in PK-15 cells. Cell Biochem Biophys 2023; 81:493-502.

Abstract
Previous studies have confirmed that Platycodon grandiflorus polysaccharide (PGPSt) has the effects of regulating immunity and anti-apoptosis, but its effect on mitochondrial damage and apoptosis caused by PRV infection is still unclear. In this research, the effects of PGPSt on the cell viability, mitochondria morphology, mitochondrial membrane potential and apoptosis caused by PRV based on PK-15 cells were respectively examined by CCK-F assay, Mito-Tracker Red CMXRos, JC-1 staining method and Western blot etc. CCK-F test results showed that PGPSt had a protective effect on the decrease of cell viability caused by PRV. The results of morphological observation found that PGPSt can improve mitochondrial morphology damage, mitochondrial swelling and thickening, and cristae fracture. Fluorescence staining test results showed that PGPSt alleviated the decrease of mitochondrial membrane potential and apoptosis in infected cells. The expression of apoptosis-related proteins showed that PGPSt down-regulated the expression of the pro-apoptotic protein Bax and up-regulated the expression of the anti-apoptotic protein Bcl-2 in infected cells. These results indicated that PGPSt protected against PRV-induced PK-15 cell apoptosis by inhibiting mitochondrial damage.

Abstract
With the increasing development of pest resistances, it is not easy to achieve satisfactory control effects by using only one agrochemical. Additionally, although the alkaloid matrine (MT) isolated from Sophora flavescens is now utilized as a botanical pesticide in China, in fact, its pesticidal activities are much lower in magnitude than those of commercially agrochemicals. To improve its pesticidal activities, here, the joint pesticidal effects of MT with another alkaloid oxymatrine (OMT) (isolated from S. flavescens) and the monoterpene essential oil 1,8-cineole (CN) (isolated from the eucalyptus leaves) were investigated in the laboratory and greenhouse conditions. Moreover, their toxicological properties were also studied. Against Plutella xylostella, when the mass ratio of MT and OMT was 8/2, good larvicidal activity was obtained; against Tetranychus urticae, when the mass ratio of MT and OMT was 3/7, good acaricidal activity was obtained. Especially when MT and OMT were combined with CN, the significant synergistic effects were observed: against P. xylostella, the co-toxicity coefficient (CTC) of MT/OMT (8/2)/CN was 213; against T. urticae, the CTC of MT/OMT (3/7)/CN was 252. Moreover, the activity changes over time of two detoxification enzymes, carboxylesterase (CarE) and glutathione S-transferase (GST) of P. xylostella treated with MT/OMT (8/2)/CN, were observed. In addition, by scanning electron microscope (SEM), the toxicological study suggested that the acaricidal activity of MT/OMT (3/7)/CN may be related to the damage of the cuticle layer crest of T. urticae.

Abstract
The pandemic of COVID-19 by SARS-CoV-2 has become a global disaster. However, we still don’t know how specific SARS-CoV-2-encoded proteins contribute to viral pathogenicity. We found that SARS-CoV-2-encoded membrane glycoprotein M could induce caspase-dependent apoptosis via interacting with PDK1 and inhibiting the activation of PDK1-PKB/Akt signaling. Our investigation further revealed that SARS-CoV-2-encoded nucleocapsid protein N could specifically enhance the M-induced apoptosis via interacting with both M and PDK1, therefore strengthening M-mediated attenuation of PDK1-PKB/Akt interaction. Furthermore, when the M-N interaction was disrupted via certain rationally designed peptides, the PDK1-PKB/Akt signaling was restored, and the boosting activity of N on the M-triggered apoptosis was abolished. Overall, our findings uncovered a novel mechanism by which SARS-CoV-2-encoded M triggers apoptosis with the assistance of N, which expands our understanding of the two key proteins of SARS-CoV-2 and sheds light on the pathogenicity of this life-threatening virus.

Abstract
Organ transplantation is an effective treatment strategy for patients with irreversible organ failure or congenital organ dysfunction. Oxymatrine (OMT) is a quinolizidine alkaloid with protective and anti-inflammatory effects on tissues and organs. The objective of this study was to investigate whether OMT could exert protective effects in cardiac allografts by regulating immune cells. In vitro cell proliferation and co-culture experiments were used to measure the effects of OMT on splenocyte proliferation and differentiation. In the in vivo study, C57BL/6 mice transplanted with BALB/c cardiac grafts were randomly divided into untreated, low-dose OMT treated, middle-dose OMT treated, high-dose OMT treated, and rapamycin-treated groups. Haematoxylin and eosin and immunohistochemical staining were used to assess pathological changes in the grafts, and fluorescence-activated cell sorting analysis was performed to measure the percentages of immune cells. The results showed that, in the in vitro study, OMT inhibited splenocyte proliferation, decreased the percentage of mature dendritic cells (DCs), and increased the percentage of regulatory T cells (Tregs) and regulatory B cells (Bregs). In the in vivo study, OMT exerted allograft protective effects by prolonging survival time, alleviating pathological damages to the cardiac allograft, decreasing intragraft CD3+ cell and increasing intragraft Foxp3+ cell infiltration, decreasing the percentages of mature DCs, increasing the percentages of Tregs and Bregs, and inhibiting the function of DCs. In conclusion, our study demonstrates that OMT exerted a protective effect on cardiac allografts by regulating immunotolerant cells. More in-depth studies of OMT may provide additional insight into the use of immunosuppressive drugs as a post-transplantation treatment strategy.

Front Physiol 2020; 11:599. [PMID: 32636757 PMCID: PMC7317027 DOI: 10.3389/fphys.2020.00599] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2020] [Accepted: 05/14/2020] [Indexed: 12/12/2022] Open
Abstract
The final pathway for the development of diabetic nephropathy (DN) into chronic renal failure in DN is glomerulosclerosis and tubulointerstitial fibrosis. Renal tubular lesions can occur in the early stage of DN renal injury. Cumulative evidence shows that oxymatrine (OMT) has a variety of biological and pharmacological properties. In recent years, more attention has been paid on the preventive and therapeutic influence of OMT on organ fibrosis. In this experiment, db/db mice were intraperitoneally injected with OMT 120 mg/kg for 8 weeks, and NRK-52E cultured with 30 mmol/L glucose and 0.1 mg/mL OMT for 48-hour. We investigated the relationship between Id2 and Twist in NRK-52E cells and the effect of OMT on the expression of E-cadherin, α-SMA, Fibronectin, and Collagen-IV by Western blot, Real-time PCR, Immunofluorescence, cell transfection, Co-Immunoprecipitation, and Luciferase assays. OMT increased the expression of Id2 but decreased that of Twist under high glucose condition in vitro and in vivo. The promoted recovery of Id2 facilitated its binding to Twist and affected E-cadherin activity inhibiting EMT and the excessive proliferation and abnormal deposition of ECM. In brief, OMT promotes Id2 to reverse EMT and exert anti-fibrotic effect in diabetic renal tubular epithelial cells by binding Id2 to Twist and affecting its transcriptional activation of downstream target genes. Or findings provide a new experimental basis for delaying the progress and for treatment of diabetic renal fibrosis.

Abstract
To develop new potential pesticides, a series of matrine-cholesterol derivatives were prepared by modifications of two non-food bioactive products matrine and cholesterol. Two N-phenylsulfonylmatrinic esters (5i and 5j) showed the most potent insecticidal activity against Mythimna separata Walker. Two N-benzylmatrinic esters (5e and 5g) exhibited the most promising aphicidal activity against Aphis citricola Van der Goot. Especially compound 5e showed good control effects in the greenhouse against A. citricola. Some interesting results of their structure-activity relationships were also observed. By reverse transcription polymerase chain reaction (RT-PCR) and quantitative real-time polymerase chain reaction (qRT-PCR) analysis of HMG-CoA reductase in apterous adults of A. citricola, it demonstrated that matrine and cholesterol may be the HMG-CoA reductase inhibitors, and the hydroxyl of cholesterol or the lactam ring of matrine may be important for acting with HMG-CoA reductase in A. citricola.

Abstract
In continuation of our program to develop natural-product-based pesticidal candidates, matrinic/oxymatrinic amides were obtained through structural optimization of matrine. N'-(4-Fluoro)phenyl-N-(4-bromo)phenylsulfonyloxymatrinic amide (IIm) showed potent insecticidal activity against Mythimna separata. N-(Un)substituted phenylsulfonylmatrinic acids (3a-c) exhibited promising acaricidal activity against Tetranychus cinnabarinus. By qRT-PCR analysis of nAChR subunits and AChE genes and determination of AChE activity of (un)treated T. cinnabarinus, it suggested that the open lactam ring of matrine and carboxyl group and (4-methyl)phenylsulfonyl of N-(4-methyl)phenylsulfonylmatrinic acid (3b) were necessary for action with α2, α4, α5, and β3 nAChR subunits; compound 3b was an inhibitor of AChE in T. cinnabarinus, and AChE was one possible target of action in T. cinnabarinus against 3b; and compound 3b may be an antagonist of nAChR and AChE in T. cinnabarinus.
