Abstract
Resibufogenin (RBG), a significant bufadienolide compound found in the traditional Chinese medicine Chansu, has garnered increasing attention in recent years for its wide range of pharmacological effects. This compound has shown promising potential in various therapeutic areas, including oncology, cardiology, and respiratory medicine. Among its notable properties, the anticancer effects of RBG are particularly striking, positioning it as a potential candidate for innovative cancer treatments. The mechanism of action of RBG is diverse, impacting various cellular processes. Its anticancer efficacy has been observed in different types of cancer cells, where it induces apoptosis and inhibits cell proliferation. Beyond its oncological applications, RBG also demonstrates substantial anti-inflammatory and antiviral activities. These properties suggest its utility in managing chronic inflammatory disorders and viral infections, respectively. The compound's cardiotonic effects are also noteworthy, providing potential benefits in cardiovascular health, particularly in heart failure management. Additionally, RBG has shown effectiveness in blood pressure regulation and respiratory function improvement, making it a versatile agent in the treatment of hypertension and respiratory disorders. However, despite these promising aspects, systematic reviews focusing specifically on RBG are limited. This article aims to address this gap by comprehensively reviewing RBG's origin, physiological, and pharmacological effects. The review will serve as a crucial reference for clinicians and researchers interested in the therapeutic applications of RBG, highlighting its potential in various medical domains. By synthesizing current research findings, this review will facilitate a deeper understanding of RBG's role in medicine and encourage further investigation into its clinical uses.

Liu L, Xiang M, Cai X, Wu B, Chen C, Cai N, Ao D. Multi-omics analyses of gut microbiota via 16S rRNA gene sequencing, LC-MS/MS and diffusion tension imaging reveal aberrant microbiota-gut-brain axis in very low or extremely low birth weight infants with white matter injury. BMC Microbiol 2023; 23:387. [PMID: 38057706 DOI: 10.1186/s12866-023-03103-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Accepted: 11/02/2023] [Indexed: 12/08/2023] Open
Abstract
OBJECTIVE The goal of this study was to comprehensively investigate the characteristics of gut microbiota dysbiosis and metabolites levels in very low or extremely low birth weight (VLBW/ELBW) infants with white matter injury (WMI). METHODS In this prospective cohort study, preterm infants with gestational age < 32 weeks and weight < 1.5 kg were investigated. Additionally, fecal samples were collected on days zero, 14d and 28d after admission to the intensive care unit. All subjects underwent brain scan via MRI and DTI at a corrected gestational age of 37 ~ 40 weeks. Based on the results of MRI examination, the VLBW/ELBW infants were divided into two groups: WMI and non-WMI. Finally, based on a multi-omics approach, we performed 16S rRNA gene sequencing, LC-MS/MS, and diffusion tension imaging to identify quantifiable and informative biomarkers for WMI. RESULT We enrolled 23 patients with and 48 patients without WMI. The results of 16S RNA sequencing revealed an increase in the number of Staphylococcus and Acinetobacter species in the fecal samples of infants with WMI, as well as increasing levels of S. caprae and A._johnsonii. LEfSe analysis (LDA ≥ 4) showed that the WMI group carried an abundance of Staphylococcus species including S. caprae, members of the phyla Bacteroidota and Actinobacteriota, and Acinetobacter species. A total of 139 metabolic markers were significantly and differentially expressed between WMI and nWMI. KEGG pathway enrichment analysis revealed that the WMI group showed significant downregulation of 17 metabolic pathways including biosynthesis of arginine and primary bile acids. The WMI group showed delayed brain myelination, especially in the paraventricular white matter and splenium of corpus callosum. Staphylococcus species may affect WMI by downregulating metabolites such as cholic acid, allocholic acid, and 1,3-butadiene. Gut microbiota such as Acinetobacter and Bacteroidetes may alter white matter structurally by upregulating metabolites such as cinobufagin. CONCLUSION Based on 16S RNA sequencing results, severe gut microbiota dysbiosis was observed in the WMI group. The results might reveal damage to potential signaling pathways of microbiota-gut-brain axis in gut microbiota. The mechanism was mediated via downregulation of the bile acid biosynthetic pathway.

Abstract
Senescent cells that accumulate with age have been shown to contribute to age-related diseases and organ dysfunction and have attracted attention as a target for anti-aging therapy. In particular, the use of senescent cell-depleting agents, or senolytics, has been shown to improve the aging phenotype in animal models. Since senescence has been implicated in the skin, particularly in fibroblasts, this study used aged human skin fibroblasts to investigate the effects of resibufogenin. A component of the traditional Chinese medicine toad venom, resibufogenin was investigated for senolytic and/or senomorphic activity. We found that the compound selectively caused senescent cell death without affecting proliferating cells, with a marked effect on the suppression of the senescence-associated secretory phenotype. We also found that resibufogenin causes senescent cell death by inducing a caspase-3-mediated apoptotic program. Administration of resibufogenin to aging mice resulted in an increase in dermal collagen density and subcutaneous fat, improving the phenotype of aging skin. In other words, resibufogenin ameliorates skin aging through selective induction of senescent cell apoptosis without affecting non-aged cells. This traditional compound may have potential therapeutic benefits in skin aging characterized by senescent cell accumulation.

Abstract
OBJECTIVES Cinobufagin is a natural active ingredient isolated from the traditional Chinese medicine Venenum Bufonis (Chinese: Chansu), which is the dried secretion of the postauricular gland or skin gland of the Bufo gargarizans Cantor or Bufo melanostictus Schneider. There is increasing evidence indicating that cinobufagin plays an important role in the treatment of cancer. This article is to review and discuss the antitumor pharmacological effects and mechanisms of cinobufagin, along with a description of its toxicity and pharmacokinetics. METHODS The public databases including PubMed, China National Knowledge Infrastructure and Elsevier were referenced, and 'cinobufagin', 'Chansu', 'Venenum Bufonis', 'anticancer', 'cancer', 'carcinoma', and 'apoptosis' were used as keywords to summarize the comprehensive research and applications of cinobufagin published up to date. KEY FINDINGS Cinobufagin can induce tumour cell apoptosis and cycle arrest, inhibit tumour cell proliferation, migration, invasion and autophagy, reduce angiogenesis and reverse tumour cell multidrug resistance, through triggering DNA damage and activating the mitochondrial pathway and the death receptor pathway. CONCLUSIONS Cinobufagin has the potential to be further developed as a new drug against cancer.

Abstract
Bufadienolides, naturally found in toad venoms having steroid-like structures, reveal antiproliferative effects at low doses. However, their application as anticancer drugs is strongly prevented by their Na+ /K+ -ATPase binding activities. Although several kinds of research were dedicated to moderating their Na+ /K+ -ATPase binding activity, still deeper fundamental knowledge is required to bring these findings into medical practice. In this work, we reviewed data related to anticancer activity of bufadienolides such as bufalin, arenobufagin, bufotalin, gamabufotalin, cinobufotalin, and cinobufagin and their derivatives. Bufotoxins, derivatives of bufadienolides containing polar molecules mainly belonging to argininyl residues, are reviewed as well. The established structures of bufotoxins have been compiled into a one-page figure to review their structures. We also highlighted advances in the structure-modification of the structure of compounds in this class. Drug delivery approaches to target these compounds to tumor cells were discussed in one section. The issues related to extraction, identification, and quantification are separated into another section.

Abstract
Cancer is the second leading cause of death worldwide. Specially, the high incidence rate and prevalence of drug resistance have rendered prostate cancer (PCa) a great threat to men’s health. Novel modalities with different structures or mechanisms are in urgent need to overcome these two challenges. Traditional Chinese medicine toad venom-derived agents (TVAs) have shown to possess versatile bioactivities in treating certain diseases including PCa. In this work, we attempted to have an overview of bufadienolides, the major bioactive components in TVAs, in the treatment of PCa in the past decade, including their derivatives developed by medicinal chemists to antagonize certain drawbacks of bufadienolides such as innate toxic effect to normal cells. Generally, bufadienolides can effectively induce apoptosis and suppress PCa cells in-vitro and in-vivo, majorly mediated by regulating certain microRNAs/long non-coding RNAs, or by modulating key pro-survival and pro-metastasis players in PCa. Importantly, critical obstacles and challenges using TVAs will be discussed and possible solutions and future perspectives will also be presented in this review. Further in-depth studies are clearly needed to decipher the mechanisms, e.g., targets and pathways, toxic effects and fully reveal their application. The information collected in this work may help evoke more effects in developing bufadienolides as therapeutic agents in PCa.

Abstract
Resibufogenin (RB) is a major active ingredient in the traditional Chinese medicine Chansu and has garnered considerable attention for its efficacy in the treatment of cancer. However, the anticancer effects and underlying mechanisms of RB on glioblastoma (GBM) remain unknown. Here, we found that RB induced G2/M phase arrest and inhibited invasion in a primary GBM cell line, P3#GBM, and two GBM cell lines, U251 and A172. Subsequently, we demonstrated that RB-induced G2/M phase arrest occurred through downregulation of CDC25C and upregulation of p21, which was caused by activation of the MAPK/ERK pathway, and that RB inhibited GBM invasion by elevating intercellular Ca2+ to suppress the Src/FAK/Paxillin focal adhesion pathway. Intriguingly, we confirmed that upon RB binding to ATP1A1, Na+-K+-ATPase was activated as a receptor and then triggered the intracellular MAPK/ERK pathway and Ca2+-mediated Src/FAK/Paxillin focal adhesion pathway, which led to G2/M phase arrest and inhibited the invasion of GBM cells. Taken together, our findings reveal the antitumor mechanism of RB by targeting the ATP1A1 signaling cascade and two key signaling pathways and highlight the potential of RB as a new class of promising anticancer agents.

Abstract
Resibufogenin (RBG) is a natural medicinal ingredient with promising cardiac protection and antitumor activity. However, poor solubility and severe gastric mucosa irritation restrict its application in the pharmaceutical field. In this study, the inclusion complex of RBG with β-cyclodextrin (β-CD) and 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) was prepared using the co-evaporation method, and the molar ratio of RBG to CD was determined to be approximately 1:2 by continuous variation plot for both CDs. The formation of inclusion complexes between RBG and each CD (RBG/β-CD and RBG/HP-β-CD) was evaluated by phase solubility study, Fourier transform infrared spectroscopy, and thin-layer chromatography. Powder X-ray diffraction and differential scanning calorimetry confirmed drug amorphization and encapsulation in the molecular cage for both CDs. Moreover, the inclusion complexes’ morphologies were observed using scanning electron microscopy. The dissolution rate of the inclusion complexes was markedly improved compared to that of RBG, and the complexes retained their antitumor activity, as shown in the in vitro cytotoxicity assay on a human lung adenocarcinoma cancer (A549) cell line. Moreover, less gastric mucosal irritation was observed for the inclusion complex. Thus, the inclusion complex should be considered a promising strategy for the delivery of poorly water-soluble anticancer agents, such as RBG.

Abstract
Cinobufagin, a bufadienolide of toad venom of Bufo bufo gargarizans, is used as a cardiotonic, central nervous system (CNS) respiratory agent, as well as an analgesic and anesthetic. However, several research showed that bufadienolide has a few side effects on the CNS, such as breathlessness or coma. Although cinobufagin was shown to display pharmacological effects in various models, the toxic effect of cinobufagin is elusive in brain cell models. The aim of this study was to explore whether cinobufagin affected viability, Ca2+ homeostasis, and reactive oxygen species (ROS) production in Gibco® Human Astrocyte (GHA) and HCN-2 neuronal cell line. In GHA cells but not in HCN-2 cells, cinobufagin (20-60 μM) induced [Ca2+ ]i rises. In terms of cell viability, chelation of cytosolic Ca2+ with 1,2-bis(2-aminophenoxy)ethane-N,N,N'N'-tetraacetic acid reduced cinobufagin-induced cytotoxicity in GHA cells. In GHA cells, cinobufagin-induced Ca2+ entry was inhibited by 2-aminoethoxydiphenyl borate or SKF96365. In a Ca2+ -free medium, treatment with thapsigargin or U73122 abolished cinobufagin-evoked [Ca2+ ]i rises. Furthermore, treatment with N-acetylcysteine reversed ROS production and cytotoxicity in cinobufagin-treated GHA cells. Together, in GHA cells but not in HCN-2 cells cinobufagin caused cytotoxicity that was linked to preceding [Ca2+ ]i rises by Ca2+ influx via store-operated Ca2+ entry and phospholipase C-dependent Ca2+ release from the endoplasmic reticulum. Moreover, cinobufagin induced ROS-associated cytotoxicity.

Analysis of Resibufogenin on Cardiac conduction reveals a species difference in the cardiac electrophysiology: Rats versus guinea pigs. Biomed Pharmacother 2021; 139:111581.

Abstract
Resibufogenin (RBG) is a chemical ingredient of Chan Su. In our research, we found RBG affected cardiac rhythm in a negative chronotropic way in vivo. The cardiac Mapping system ex vivo and the patch clamp in vitro were used to explore how RBG influenced the cardiac electrophysiological properties. The negative chronotropic action of RBG at 100 μM might be attribute to prolongation in the atrioventricular conduction time and reduction in the ventricular conduction velocity. Using whole-cell patch clamp in ventricular myocytes of adult rats, we found that RBG prolonged the action potential duration (APD) in APD20, APD50, and APD90 at 100 μM and inhibited calcium currents (ICa), total outward potassium currents (IK), and transient outward potassium current (Ito) in a concentration-dependent manner, but not on the inward rectifying potassium current (IK1). Notably, RBG had a potent proarrhythmic action ex vivo in the isolated perfused guinea pig hearts at 10 μM, but not in rats. To avoid the potential cardiotoxicity derived from the distributional differences of ion channels among species, the effect of RGB on IKr in hERG-HEK293 cells was detected. The IC50 of RGB on IKr was more than 100 μM. In summary, all these results indicated that the negative chronotropic action of RBG relied on the blocking activities on multiple ion channels, and the species-difference of proarrhythmic effects might result from lack of the Ito on the myocardial membrane of guinea pigs. Anyhow, the cardiotoxicity observed in guinea pigs required further detailed studies to mitigate the potential risks in the clinical application of Chan Su.

Abstract
OBJECTIVE To explore the mechanism of Aitongxiao in improving pain symptoms of rats with cancer pain. METHODS Walker 256 breast cancer cells were injected into the right tibial bone marrow cavity of normal female rats to establish a rat model of tibial cancer pain. The rats with successful model replication were randomly divided into normal group (NG), Hank solution group (HSG), cancer pain model group (CPMG), and Aitongxiao+cancer pain model group (ATX+CPMG). The pain response score, mechanical pain hindpaw withdrawal threshold, and latent heat pain of rats were evaluated, and the changes of serum IL-1β, TNF-α, PGE2 and blood cell counts of rats were detected. RESULTS Compared with the NG, the pain response score was increased, the mechanical pain hindpaw withdrawal threshold and latent heat pain were decreased, and IL-1β, TNF-α, and PGE2 were increased in CPMG. Compared with the CPMG, the pain response score was decreased, the mechanical pain hindpaw withdrawal threshold and latent heat pain were increased, and IL-1β, TNF-α, and PGE2 were decreased in ATX+CPMG. There was no significant change in blood cell count in each group. CONCLUSION Aitongxiao can improve the pain symptoms of rats with tibial cancer pain. Its mechanism may be related to the reduction of IL-1β, TNF-α, and PGE2 levels.

Abstract
Venenum Bufonis (VB), also called Chan Su in China, has been extensively used as a traditional Chinese medicine (TCM) for treating heart failure (HF) since ancient time. However, the active components and the potential anti-HF mechanism of VB remain unclear. In the current study, the major absorbed components and metabolites of VB after oral administration in rats were first collected from literatures. A total of 17 prototypes and 25 metabolites were gathered. Next, a feasible network-based pharmacological approach was developed and employed to explore the therapeutic mechanism of VB on HF based on the collected constituents. In total, 158 main targets were screened out and considered as effective players in ameliorating HF. Then, the VB components-main HF putative targets-main pathways network was established, clarifying the underlying biological process of VB on HF. More importantly, the main hubs were found to be highly enriched in adrenergic signalling in cardio-myocytes. After verified by molecular docking studies, four key targets (ATP1A1, GNAS, MAPK1 and PRKCA) and three potential active leading compounds (bufotalin, cinobufaginol and 19-oxo-bufalin) were identified, which may play critical roles in cardiac muscle contraction. This study demonstrated that the integrated strategy based on network pharmacology and molecular docking was helpful to uncover the synergistic mechanism of multiple constituents in TCM.

The spinal microglial IL-10/β-endorphin pathway accounts for cinobufagin-induced mechanical antiallodynia in bone cancer pain following activation of α7-nicotinic acetylcholine receptors. J Neuroinflammation 2020; 17:75. [PMID: 32113469 PMCID: PMC7049212 DOI: 10.1186/s12974-019-1616-z] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2019] [Accepted: 10/09/2019] [Indexed: 02/06/2023] Open
Abstract
Background Cinobufagin is the major bufadienolide of Bufonis venenum (Chansu), which has been traditionally used for the treatment of chronic pain especially cancer pain. The current study aimed to evaluate its antinociceptive effects in bone cancer pain and explore the underlying mechanisms. Methods Rat bone cancer model was used in this study. The withdrawal threshold evoked by stimulation of the hindpaw was determined using a 2290 CE electrical von Frey hair. The β-endorphin and IL-10 levels were measured in the spinal cord and cultured primary microglia, astrocytes, and neurons. Results Cinobufagin, given intrathecally, dose-dependently attenuated mechanical allodynia in bone cancer pain rats, with the projected Emax of 90% MPE and ED50 of 6.4 μg. Intrathecal cinobufagin also stimulated the gene and protein expression of IL-10 and β-endorphin (but not dynorphin A) in the spinal cords of bone cancer pain rats. In addition, treatment with cinobufagin in cultured primary spinal microglia but not astrocytes or neurons stimulated the mRNA and protein expression of IL-10 and β-endorphin, which was prevented by the pretreatment with the IL-10 antibody but not β-endorphin antiserum. Furthermore, spinal cinobufagin-induced mechanical antiallodynia was inhibited by the pretreatment with intrathecal injection of the microglial inhibitor minocycline, IL-10 antibody, β-endorphin antiserum and specific μ-opioid receptor antagonist CTAP. Lastly, cinobufagin- and the specific α-7 nicotinic acetylcholine receptor (α7-nAChR) agonist PHA-543613-induced microglial gene expression of IL-10/β-endorphin and mechanical antiallodynia in bone cancer pain were blocked by the pretreatment with the specific α7-nAChR antagonist methyllycaconitine. Conclusions Our results illustrate that cinobufagin produces mechanical antiallodynia in bone cancer pain through spinal microglial expression of IL-10 and subsequent β-endorphin following activation of α7-nAChRs. Our results also highlight the broad significance of the recently uncovered spinal microglial IL-10/β-endorphin pathway in antinociception.

Abstract
BACKGROUND Neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, and cerebral ischemic stroke, impose enormous socio-economic burdens on both patients and health-care systems. However, drugs targeting these diseases remain unsatisfactory, and hence there is an urgent need for the development of novel and potent drug candidates. METHODS Animal toxins exhibit rich diversity in both proteins and peptides, which play vital roles in biomedical drug development. As a molecular tool, animal toxin peptides have not only helped clarify many critical physiological processes but also led to the discovery of novel drugs and clinical therapeutics. RESULTS Recently, toxin peptides identified from venomous animals, e.g. exenatide, ziconotide, Hi1a, and PcTx1 from spider venom, have been shown to block specific ion channels, alleviate inflammation, decrease protein aggregates, regulate glutamate and neurotransmitter levels, and increase neuroprotective factors. CONCLUSION Thus, components of venom hold considerable capacity as drug candidates for the alleviation or reduction of neurodegeneration. This review highlights studies evaluating different animal toxins, especially peptides, as promising therapeutic tools for the treatment of different neurodegenerative diseases and disorders.

Abstract
OBJECTIVE In this study, we aimed to compare the analgesic and toxic effects of Venenum Bufonis (VB) with those of cinobufagin (CBG), a monomer isolated from VB, to provide the experimental basis for further research and development of VB. METHODS After intragastric administration, the analgesic activities of VB and CBG were compared using the hot plate test and acetic acid-induced writhing test. Their side effects were also compared using hepatotoxicity, acute toxicity, cytotoxicity, and hemolytic toxicity tests, as well as by evaluating their effects on rat heart rate. RESULTS In the hot plate test, both drugs prolonged paw withdrawal latency; however, CBG-treated mice exhibited significantly longer latency than VB-treated mice. In the acetic acid-induced writhing test, both drugs inhibited mouse writhing; however, the inhibitory effects of CBG were stronger. In addition, VB significantly increased serum aspartate aminotransferase (AST) levels, whereas CBG did not these levels. The LD50 of VB and CBG was 36.25 and 4.78 mg/kg, respectively. Both drugs increased the heart rate with CBG exhibiting stronger effects. Moreover, results showed that the cytotoxicity of CBG was more dose-dependent than that of VB. Both VB and CBG showed low hemolytic toxicity. CONCLUSIONS Both VB and CBG exhibited analgesic effects and low hemolytic toxicity; however, the latter showed stronger analgesic activity and less hepatotoxicity. Additionally, both VB and CBG increased the heart rate; however, CBG had stronger effects and higher acute toxicity.

Abstract
The effects of cinobufacini on apoptosis of human bladder cancer T24 cells and the expression of autophagy-related genes and proteins were studied. The human bladder cancer T24 cells were selected, and the inhibitory effect of cinobufacini on the proliferation of human bladder cancer cells was detected by cell viability assay. Flow cytometry and Hoechst staining were used to detect the changes in the apoptosis of bladder cancer cells after being treated with cinobufacini; the changes in the expression levels of human bladder cancer cell apoptosis-related genes and proteins, cleaved caspase-3, Bax, B-cell lymphoma-2 (Bcl-2) and autophagy-related genes and proteins, p62, light chain 3 (LC3) and autophagy-related protein 7 (Atg7) after treatment with cinobufacini were detected by western blot analysis and reverse transcription polymerase chain reaction (RT-PCR). 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay. The results showed that 0.1 mg/ml cinobufacini significantly inhibited the proliferation of human bladder cancer cells cultured in vitro (P<0.01), and it was dose- and time-dependent. Both flow cytometry and Hoechst staining showed that cinobufacini promoted the apoptosis of cells (P<0.01), and the level of cell apoptosis increased with the increase of drug concentration. Both western blot analysis and RT-PCR showed that cinobufacini could decrease the expression level of Bcl-2 in T24 cells (P<0.01), increase the expression levels of Bax and cleaved caspase-3 (P<0.01), increase the ratio of Bax/Bcl-2 (P<0.01), upregulate the expression level of the angiotensin-related protein p62 (P<0.01), reduce the ratio of LC3-II/I (P<0.01) and decrease the expression level of Atg7 (P<0.01). After treatment with rapamycin, the expression levels of Bcl-2, Bax, cleaved caspase-3, autophagy-related genes and proteins, p62, LC3-II/I and Atg7 were similar to those in the control group. Cinobufacini can inhibit the autophagy activation of bladder cancer cells, thus promoting apoptosis of bladder cancer T24 cells and inhibiting the proliferation of T24 cells, which may provide a theoretical basis for the development of new anti-bladder cancer drugs.

Abstract
Liver cancer is one of the major diseases affecting human health. Modified drug delivery systems through the asialoglycoprotein receptor, which is highly expressed on the surface of hepatocytes, have become a research focus for the treatment of liver cancer. Resibufogenin (RBG) is a popular traditional Chinese medicine and natural anti-cancer drug that was isolated from Chansu, but its cardiotoxicity and hydrophobicity have limited its clinical applications. Galactosyl-succinyl-poloxamer 188 and galactosyl-succinyl-poloxamer 188-polylactide-co-glycolide (Gal-SP188–PLGA) were synthesized using galactose, P188, and PLGA to achieve active liver-targeting properties. RBG-loaded Gal-SP188–PLGA nanoparticles (RGPPNs) and coumarin-6-loaded Gal-SP188–PLGA nanoparticles (CGPPNs) were prepared. The in vitro cellular uptake, cytotoxicity, and apoptosis of nanoparticles in HepG2 cells were analyzed. The in vivo therapeutic effects of nanoparticles were assessed in a hepatocarcinogenic mouse model. The results showed that Gal-SP188–PLGA was successfully synthesized. The cellular uptake assay demonstrated that CGPPNs had superior active liver-targeting properties. The ratio of apoptotic cells was increased in the RGPPN group. In comparison to the other groups, RGPPNs showed superior in vivo therapeutic effects and anticancer efficacy. Thus, the active liver-targeting RGPPNs, which can enhance the pharmacological effects and decrease the toxicity of RBG, are expected to become a promising and effective treatment for liver cancer.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Venenum Bufonis (VB), also called toad venom, has been widely used in clinic as a cardiotonic, anohyne and antineoplastic agents both in China and other Asian countries. However, its neurotoxicity and cardiotoxicity limit its wide clinical application. Compared with extensive attention attracted with cardiotoxicity, the toxic effect of VB on Central Nervous System (CNS) is much less studied. AIM OF THE RESEARCH This study was performed to examine the neurotoxicity caused by VB on Sprague Dawley (SD) rats, then to clarify the mechanism in vivo by investigating its action on the neuroinflammation which possibly attributed to the activation of nuclear factor κB (NF-κB) pathway and the attenuation of brain-derived neurotrophic factor (BDNF). MATERIALS AND METHODS Rats administrated with 0.5% carboxymethyl cellulose sodium salt (CMC-Na) aqueous solution and VB (100mg/kg, 200mg/kg and 400mg/kg) were sacrificed at 2h, 4h, 6h, 8h, 24h and 48h. The brain level of neurotransmitters and their corresponding receptors, pro-inflammatory cytokines, BDNF/TrkB and NF-κB pathway-related proteins were examined, respectively. RESULTS VB administration induced severe neurologic damage and neuroinflammation, as indicated by the disordered 5-hydroxytryptamine (5-HT), dopamine (DA) and their corresponding receptors, together with the over production of inflammatory cytokines including interleukin-6 (IL-6), interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α). VB also notably promoted the expression of p-NF-κBp65, p-IκBα, p-IKKα and p-IKKβ and down-regulated the expression of BDNF and TrkB. CONCLUSION This study demonstrates that VB triggers neurotoxicity which probably is induced by neuroinflammation via activating of NF-κB pathway and attenuating the expression of BDNF.

Zhang Y. Why do we study animal toxins? DONG WU XUE YAN JIU = ZOOLOGICAL RESEARCH 2015; 36:183-222. [PMID: 26228472 PMCID: PMC4790257 DOI: 10.13918/j.issn.2095-8137.2015.4.183] [Citation(s) in RCA: 50] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 04/01/2015] [Accepted: 04/25/2015] [Indexed: 12/31/2022]
Abstract
Venom (toxins) is an important trait evolved along the evolutionary tree of animals. Our knowledges on venoms, such as their origins and loss, the biological relevance and the coevolutionary patterns with other organisms are greatly helpful in understanding many fundamental biological questions, i.e., the environmental adaptation and survival competition, the evolution shaped development and balance of venoms, and the sophisticated correlations among venom, immunity, body power, intelligence, their genetic basis, inherent association, as well as the cost-benefit and trade-offs of biological economy. Lethal animal envenomation can be found worldwide. However, from foe to friend, toxin studies have led lots of important discoveries and exciting avenues in deciphering and fighting human diseases, including the works awarded the Nobel Prize and lots of key clinic therapeutics. According to our survey, so far, only less than 0.1% of the toxins of the venomous animals in China have been explored. We emphasize on the similarities shared by venom and immune systems, as well as the studies of toxin knowledge-based physiological toxin-like proteins/peptides (TLPs). We propose the natural pairing hypothesis. Evolution links toxins with humans. Our mission is to find out the right natural pairings and interactions of our body elements with toxins, and with endogenous toxin-like molecules. Although, in nature, toxins may endanger human lives, but from a philosophical point of view, knowing them well is an effective way to better understand ourselves. So, this is why we study toxins.
