Alkaloids of Aconiti Lateralis Radix Praeparata inhibit growth of non-small cell lung cancer by regulating PI3K/Akt-mTOR signaling and glycolysis.

Aconiti Lateralis Radix Praeparata (Fuzi in Chinese) is widely used in the clinical treatment of tumors. This study aims to explore the active fractions and underlying mechanisms of Fuzi in the treatment of non-small cell lung cancer (NSCLC). Fuzi alkaloids (FZA) is prepared and found to inhibit the growth of NSCLC both in vitro and in vivo significantly. A total of 53 alkaloids are identified in FZA by UPLC-Q-TOF-MS. Proteomics experiment show that 238 differentially expressed proteins regulated by FZA are involved in amino acid anabolism, pyrimidine metabolism and PI3K/Akt-mTOR signaling pathway. Metabolomics analyses identify 32 significant differential metabolites which are mainly involved in amino acid metabolism, TCA cycle and other pathways. Multi-omics research combined with molecular biological assays suggest that FZA might regulate glycolysis through PI3K/Akt-mTOR pathway to treat NSCLC. The study lays a foundation for the anti-cancer investigation of Fuzi and provides a possible scientific basis for its clinical application.

[Mechanism of Paeoniae Radix Rubra and Aconiti Lateralis Radix Praeparata herbal pair in promoting hepatocellular regeneration in chronic acute liver failure based on HGF/PI3K/Akt signaling axis].

Based on the hepatocyte growth factor(HGF)/phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt) signaling axis, this study investigated the therapeutic effect of Paeoniae Radix Rubra and Aconiti Lateralis Radix Praeparata(PRR-ALRP) her-bal pair on acute-on-chronic liver failure(ACLF) rats and its impact on hepatocellular regeneration. The rat model of ACLF was constructed by subcutaneous and tail vein injection of bovine serum albumin combined with intraperitoneal injection of lipopolysaccharides(LPS)+D-galactosamine(D-GalN). The rats were divided into normal control(NC) group, model(vehicle) group, PRR-ALRP(5.85 g·kg~(-1)) group, and hepatocyte growth factor granules(HGFG, 4.05 g·kg~(-1)) group. Hematoxylin-eosin(HE) staining was used to observe pathological changes in rat liver tissues. Serum alanine aminotransferase(ALT), aspartate transaminase(AST), and total bilirubin(TBIL) were detected using an automatic biochemical analyzer. The levels of interleukin-1ß(IL-1ß) and tumor necrosis factor-α(TNF-α) inflammatory factors were detected by ELISA. Immunofluorescence staining was used to detect the positive expression of proliferating cell nuclear antigen(PCNA), antigen identified by monoclonal antibody(Ki67), and cell cycle protein B1(CyclinB1). Real-time fluorescence-based quantitative polymerase chain reaction(RT-qPCR) and Western blot were used to detect the mRNA and protein expression levels of HGF, growth factor receptor-bound protein 1(Gab1), PI3K, Akt, phosphorylated PI3K(p-PI3K), and phosphorylated Akt(p-Akt). The results showed that compared with the vehicle group, the PRR-ALRP group had reduced liver tissue pathological scores, improved liver function, and reduced inflammatory response, with enhanced PCNA, Ki67, and CyclinB1 fluorescence expression. Furthermore, compared with the model group, the PRR-ALRP group showed upregulated expression of HGF and Gab1 proteins, as well as activation of PI3K and Akt phosphorylation. These findings suggest that PRR-ALRP herbal pair exerts anti-liver failure effects by alleviating hepatocyte inflammatory damage and promoting hepatocellular regeneration, and its specific regulatory mechanism may be related to the activation of the HGF/PI3K/Akt signaling pathway.

Structural Modification and Characteristics of Lappaconitine Alkaloid for the Discovery of Bioactive Components by Hypervalent Iodine Reagent.

Lappaconitine, a diterpene alkaloid isolated from Aconitum sinomontanum Nakai, exhibits a wide range of biological activities, making it a promising candidate for the development of novel derivatives with therapeutic potential. In our research, we executed a two-step transformation via oxidative cleavage of lappaconitine's vicinal diol using the hypervalent iodine reagent PhI(OAc)2, followed by strong alkaline hydrolysis. This approach yielded four new unanticipated compounds, whose structures were identified by spectroscopic methods and/or X-ray crystallography. Thus, we proposed plausible reaction mechanisms for their formations and particularly investigated the remarkable diastereoselectivity for the formation of single stereoisomer 8 observed during the alkaline hydrolysis step. Among them, compound 8 (code name: QG3030) demonstrated both enhanced osteogenic differentiation of human mesenchymal stem cells and significant osteogenic effect in an ovariectomized rat model with no acute oral toxicity.

Aconite-Induced Metamorphosis From Beauty to Ugliness in a Japanese Tale.

The authors present a narrative that details the cause and process of a woman's transformation from beauty to ugliness in a Japanese tale. In " Tokaido Yotsuya Kaidan ," the metamorphosis from a beauty to an ugly woman is analyzed. After taking medication to recover from childbirth, Oiwa's face became disfigured and grotesque. Oiwa: It seems to be good for my blood, but when I drink it, it causes fraying and breakdown, causing sudden pain. I feel a numbing dullness. When she looked at herself in the mirror, she was shocked. Oiwa: What's wrong with my face? I hate this, it's such a disgusting thing. Neighbor: It was a lie that the medicine you drank was a helpful medicine that protects the appearance of people's faces. Your face is that of a wicked woman (). Oiwa: Is it really me? Why does she have the face of an evil woman? Her hair falls out in a gruesome combing scene, driving her mad. The poison Oiwa took was aconite, which grows wild in Japan. Both aconite tincture and raw aconite roots contain high concentrations of Aconitum alkaloids, which can penetrate the stratum corneum following the diffusion gradient. As her hair fell out during a horrific combing session, she abandoned her maternal role and sought revenge, having lost what she considered a symbol of her femininity. In treating female patients with facial disfigurement, it is important to be mindful of their psychological state, akin to that of Oiwa, who became disfigured through no fault of her own.

Unlocking renal Restoration: Mesaconine from Aconitum plants restore mitochondrial function to halt cell apoptosis in acute kidney injury.

Acute kidney injury (AKI) is characterized by a sudden decline in renal function. Traditional Chinese medicine has employed Fuzi for kidney diseases; however, concerns about neurotoxicity and cardiotoxicity have constrained its clinical use. This study explored mesaconine, derived from processed Fuzi, as a promising low-toxicity alternative for AKI treatment. In this study, we assessed the protective effects of mesaconine in gentamicin (GM)-induced NRK-52E cells and AKI rat models in vitro and in vivo, respectively. Mesaconine promotes the proliferation of damaged NRK-52E cells and down-regulates intracellular transforming growth factor ß1 (TGF-ß1) and kidney injury molecule 1 (KIM-1) to promote renal cell repair. Concurrently, mesaconine restored mitochondrial morphology and permeability transition pores, reversed the decrease in mitochondrial membrane potential, mitigated mitochondrial dysfunction, decreased ATP production, inhibited inflammatory factor release, and reduced early apoptosis rates. In vivo, GM-induced AKI rat models exhibited elevated AKI biomarkers, in which mesaconine was effectively reduced, indicating improved renal function. Mesaconine enhanced superoxide dismutase activity, reduced malondialdehyde content, alleviated inflammatory infiltrate, mitigated tubular and glomerular lesions, and downregulated NF-κB (nuclear factor-κb) p65 expression, leading to decreased tumor necrosis factor-α (TNF-α) and IL-1ß (interleukin-1ß) levels in GM-induced AKI animals. Furthermore, mesaconine inhibited the expression of renal pro-apoptotic proteins (Bax, cytochrome c, cleaved-caspase 9, and cleaved-caspase 3) and induced the release of the anti-apoptotic protein bcl-2, further suppressing apoptosis. This study highlighted the therapeutic potential of mesaconine in GM-induced AKI. Its multifaceted mechanisms, including the restoration of mitochondrial dysfunction, anti-inflammatory and antioxidant effects, and apoptosis mitigation, make mesaconine a promising candidate for further exploration in AKI management.

Exploring Potential Targets and Pathways of Toxicity Attenuation Through Serum Pharmacochemistry and Network Pharmacology in the Processing of Aconiti Lateralis Radix Praeparata.

Aconiti Lateralis Radix Praeparata (Fuzi, FZ) is a frequently utilized traditional Chinese medicine (TCM) in clinical settings. However, its toxic and side effects, particularly cardiac injury, are apparent, necessitating processing before use. To investigate the mechanism of toxicity induced by absorbed components and the mitigating effect of processed FZ, we established a comprehensive method combining serum pharmacochemistry and a network pharmacology approach. In total, 31 chemical components were identified in the plasma, with a general decrease in response intensity observed for these components in processed FZ. Subsequently, four components were selected for network pharmacology analysis. This analysis revealed 150 drug action targets and identified 1162 cardiac toxicity targets. Through intersection analysis, 41 key targets related to cardiac toxicity were identified, along with 9 significant Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. The most critical targets identified were AKT1, MTOR, and PARP1. The key biological pathways implicated were adrenergic signaling in cardiomyocytes, proteoglycans in cancer, and the calcium signaling pathway. Significant differences were observed in histological staining and biochemical indicators in the cardiac tissue of rats treated with FZ, indicating that processing could indeed reduce its cardiotoxicity. Indeed, this article presents a valuable strategy for elucidating the toxification mechanism of toxic TCM.

Aconitum coreanum and processed products on its base prevent stroke via the PI3K/Akt and KEAP1/NRF2 in the in vivo study.

Aconitum coreanum (A. coreanum), a traditional Chinese medicine, has been proved to treat ischemic stroke (IS). However, the mechanisms of A. coreanum's anti-stroke is currently unknown. This study aimed to uncover the effect and mechanisms of A. coreanum. And study raw Aconitum coreanum (RA) and steamed Aconitum coreanum (SA) and Aconitum coreanum processed with ginger and Alumen (GA) on the mechanism of the pharmacological action of treating IS. Determining whether the efficacy is affected after processing. The right unilateral ligation of the carotid artery of gerbils was used to mimic IS. The neurological function score, infarct volume, oxidative stress level and inflammatory factor expression were measured in gerbils after IS. Western blot and immunofluorescence analyses were conducted to evaluate the expression of related proteins. Metabolomic analyzes IS-related metabolic pathways in urinary metabolites. RA, SA and GA significantly improved the infarct volume and behavioral score of IS gerbils, increased the expression of brain tissue superoxide dismutase (SOD), glutathione (GSH), nitric oxide (NO) and decreased the content of malondialdehyde (MDA), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α). Western blot and immunofluorescence analysis results showed that RA, SA and GA significantly increased the expression of P-Akt, PI3K, HO-1 and KEAP1. Metabolomic studies identified 112 differential metabolites, including L-Proline, Riboflavin, Leukotriene D4, and 7-Methylxanthine, as potential biomarkers of stroke, involving 14 metabolic pathways including riboflavin metabolism, pyrimidine metabolism, and purine metabolism. Our findings indicated that A. coreanum protected against cerebral ischemia injury probably via the PI3K/Akt and KEAP1/NRF2 pathway. A. coreanum before and after processing both had a protective effect against IS brain injury in gerbils. The A. coreanum efficacy was not reduced after processing. Even compared to RA, SA had better efficacy.

Modulation of cellular metabolism and alleviation of bacterial dysbiosis by Aconiti Lateralis Radix Praeparata in non-small cell lung cancer treatment.

BACKGROUND: Non-small cell lung cancer (NSCLC) is a highly prevalent and fatal form of lung cancer. In China, Aconiti Lateralis Radix Praeparata (Fuzi in Chinese), derived from the lateral root of Aconitum carmichaeli Debx. (Ranunculaceae, Aconitum), is extensively prescribed to treat cancer in traditional medicine and clinical practice. However, the precise mechanism by which Fuzi treats NSCLC remains unknown. PURPOSE: This article aims to assess the efficacy of Fuzi against NSCLC and elucidate its underlying mechanism. METHODS: Marker ingredients of Fuzi decoction were quantified using UPLC-TSQ-MS. The effectiveness of Fuzi on NSCLC was evaluated using a xenograft mouse model. Subsequently, a comprehensive approach involving network pharmacology, serum metabolomics, and 16S rDNA sequencing was employed to investigate the anti-NSCLC mechanism of Fuzi. RESULTS: Pharmacological evaluation revealed significant tumour growth inhibition by Fuzi, accompanied by minimal toxicity. Network pharmacology identified 29 active Fuzi compounds influencing HIF-1, PI3K/Akt signalling, and central carbon metabolism in NSCLC. Integrating untargeted serum metabolomics highlighted 30 differential metabolites enriched in aminoacyl-tRNA biosynthesis, alanine, aspartate, and glutamate metabolism, and the tricarboxylic acid (TCA) cycle. Targeted serum metabolomics confirmed elevated glucose content and reduced levels of pyruvate, lactate, citrate, α-ketoglutarate, succinate, fumarate, and malate following Fuzi administration. Furthermore, 16S rDNA sequencing assay showed that Fuzi ameliorated the dysbiosis after tumorigenesis, decreased the abundance of Proteobacteria, and increased that of Firmicutes and Bacteriodetes. PICRUSt analysis revealed that Fuzi modulated the pentose phosphate pathway of the gut microbiota. Spearman correlation showed that Proteobacteria and Escherichia_Shigella accelerated the TCA cycle, whereas Bacteroidota, Bacteroides, and Lachnospiraceae_NK4A136_group suppressed the TCA cycle. CONCLUSIONS: This study firstly introduces a novel NSCLC mechanism involving Fuzi, encompassing energy metabolism and intestinal flora. It clarifies the pivotal role of the gut microbiota in treating NSCLC and modulating the TCA cycle. Moreover, these findings offer valuable insights for clinical practices and future research of Fuzi against NSCLC.

Investigation of polysaccharide from Radix Aconiti Lateralis Preparata (Fuzi) cardio protective effect on doxorubicin-induced chronic cardiotoxicity.

OBJECTIVES: Doxorubicin (DOX) is a chemotherapy drug for treating malignant tumours. However, its cardiotoxicity has limited its clinical application. The Radix Aconiti Lateralis Preparata, also known as Fuzi, has been used for treating heart failure. Nevertheless, there is still a deficiency of claeity as to whether the Fuzi polysaccharide (FPS) may prevent the side effects of DOX. METHODS: Mice were intraperitoneally administered DOX (15 mg/kg) to establish a mouse model of DOX-induced chronic cardiotoxicity (DICC). The mice were then administered different doses of FPS or enalapril intragastrically. KEY FINDINGS: In the DOX group, the activity of CK-MB and LDH and the content of NT-proBNP in serum of mice were increased. Myocardial infiltration of inflammatory cells and cytoplasmic vacuolation occurred. Levels of NLRP3, ASC, Caspase-1, IL-1ß, IL-18, IL-6, and Bax increased, whereas levels of Bcl-2, STAT3, and p-STAT3 decreased. After administering FPS (100 mg/kg and 200 mg/kg), there were reductions in CK-MB activity and NT-proBNP levels. Cytoplasmic vacuolation, interstitial infiltration of blood, and infiltration of inflammatory cells were alleviated. The changes in protein expression mentioned above were reversed. CONCLUSIONS: FPS can protect heart function and structure in DICC mice by inhibiting NLRP3 inflammasome-mediated pyroptosis and IL-6/STAT3 pathway-induced apoptosis.

Sensitive quantitation of ultra-trace toxic aconitines in complex matrices by perfusion nano-electrospray ionization mass spectrometry combined with gas-liquid microextraction.

The accurate analysis of ultra-trace (e.g. <10-4 ng/mL) substances in complex matrices is a burdensome but vital problem in pharmaceutical analysis, with important implications for precise quality control of drugs, discovery of innovative medicines and elucidation of pharmacological mechanisms. Herein, an innovative constant-flow perfusion nano-electrospray ionization (PnESI) technique was developed firstly features significant quantitative advantages in high-sensitivity ambient MS analysis of complex matrix sample. More importantly, double-labeled addition enrichment quantitation strategies of gas-liquid microextraction (GLME) were proposed for the first time, allowing highly selective extraction and enrichment of specific target analytes in a green and ultra-efficient (>1000-fold) manner. Using complex processed Aconitum herbs as example, PnESI-MS directly enabled the qualitative and absolute quantitative analysis of the processed Aconitum extracts and characterized the target toxic diester alkaloids with high sensitivity, high stability, wide linearity range, and strong resistance to matrix interference. Further, GLME device was applied to obtain the highly specific enrichment of the target diester alkaloids more than 1000-fold, and accurate absolute quantitation of trace aconitine, mesaconitine, and hypaconitine in the extracts of Heishunpian, Zhichuanwu and Zhicaowu was accomplished (e.g., 0.098 pg/mL and 0.143 pg/mL), with the quantitation results well below the LODs of aconitines from any analytical instruments available. This study built a systematic strategy for accurate quantitation of ultra-trace substances in complex matrix sample and expected to provide a technological revolution in many fields of pharmaceutical research.

Comprehensive insight into the pharmacology, pharmacokinetics, toxicity, detoxification and extraction of hypaconitine from Aconitum plants.

ETHNOPHARMACOLOGICAL RELEVANCE: Hypaconitine (HA), a diterpenoid alkaloid, mainly derived from Aconitum plants such as Acoitum carmichaeli Debx. And Aconitum nagarum Stapf., has recently piqued significant interest among the scientific community given its multifaceted attributes including anti-inflammatory, anticancer, analgesic, and cardio-protective properties. AIM OF THE STUDY: This review presents a comprehensive exploration of the research advancements regarding the traditional uses, pharmacology, pharmacokinetics, toxicity, and toxicity reduction of HA. It aims to provide a thorough understanding of HA's multifaceted properties and its potential applications in various fields. MATERIALS AND METHODS: A systematic literature search was conducted using several prominent databases including PubMed, Web of Science, NCBI, and CNKI. The search was performed using specific keywords such as "hypaconitine," "heart failure," "anti-inflammatory," "aconite decoction," "pharmacological," "pharmacokinetics," "toxicity," "detoxification or toxicity reduction," and "extraction and isolation." The inclusion of these keywords ensured a comprehensive exploration of relevant studies and enabled the retrieval of valuable information pertaining to the various aspects of HA. RESULTS: Existing research has firmly established that HA possesses a range of pharmacological effects, encompassing anti-cardiac failure, anti-inflammatory, analgesic, and anti-tumor properties. The therapeutic potential of HA is promising, with potential applications in heart failure, ulcerative colitis, cancer, and other diseases. Pharmacokinetic studies suggest that HA exhibits high absorption rates, broad distribution, and rapid metabolism. However, toxic effects of HA on the nerves, heart, and embryos have also been observed. To mitigate these risks, HA needs attenuation before use, with the most common detoxification methods being processing and combined use with other drugs. Extraction methods for HA most commonly include cold maceration, soxhlet reflux extraction, and ultrasonic-assisted extraction. Despite the potential therapeutic benefits of HA, further research is warranted to elucidate its anti-heart failure effects, particularly in vivo, exploring aspects such as in vivo metabolism, distribution, and metabolites. Additionally, the therapeutic effects of HA monomers on inflammation-induced diseases and tumors should be validated in a more diverse range of experimental models, while the mechanisms underlying the therapeutic effects of HA should be investigated in greater detail. CONCLUSION: This review serves to emphasize the therapeutic potential of HA and highlights the crucial need to address its toxicity concerns before considering clinical application. Further research is required to comprehensively investigate the pharmacological properties of HA, with particular emphasis on its anti-cardiac failure and anti-inflammatory activities. Such research endeavors have the potential to unveil novel treatment avenues for a broad spectrum of diseases.

Therapeutic Potentials of Aconite-like Alkaloids: Bioinformatics and Experimental Approaches.

Compounds from plants that are used in traditional medicine may have medicinal properties. It is well known that plants belonging to the genus Aconitum are highly poisonous. Utilizing substances derived from Aconitum sp. has been linked to negative effects. In addition to their toxicity, the natural substances derived from Aconitum species may have a range of biological effects on humans, such as analgesic, anti-inflammatory, and anti-cancer characteristics. Multiple in silico, in vitro, and in vivo studies have demonstrated the effectiveness of their therapeutic effects. In this review, the clinical effects of natural compounds extracted from Aconitum sp., focusing on aconitelike alkaloids, are investigated particularly by bioinformatics tools, such as the quantitative structure- activity relationship method, molecular docking, and predicted pharmacokinetic and pharmacodynamic profiles. The experimental and bioinformatics aspects of aconitine's pharmacogenomic profile are discussed. Our review could help shed light on the molecular mechanisms of Aconitum sp. compounds. The effects of several aconite-like alkaloids, such as aconitine, methyllycacintine, or hypaconitine, on specific molecular targets, including voltage-gated sodium channels, CAMK2A and CAMK2G during anesthesia, or BCL2, BCL-XP, and PARP-1 receptors during cancer therapy, are evaluated. According to the reviewed literature, aconite and aconite derivatives have a high affinity for the PARP-1 receptor. The toxicity estimations for aconitine indicate hepatotoxicity and hERG II inhibitor activity; however, this compound is not predicted to be AMES toxic or an hERG I inhibitor. The efficacy of aconitine and its derivatives in treating many illnesses has been proven experimentally. Toxicity occurs as a result of the high ingested dose; however, the usage of this drug in future research is based on the small quantity of an active compound that fulfills a therapeutic role.

Songorine ameliorates LPS-induced sepsis cardiomyopathy by Wnt/ß-catenin signaling pathway-mediated mitochondrial biosynthesis.

Septic cardiomyopathy (SCM) is manifested by impairment of cardiac contractile function with myocardial mitochondrial dysregulation. Natural product, songorine (SGR), a diterpenoid alkaloid derived from the lateral root of Aconitum carmichaeli, has been reported for the treatment of heart failure. Here, the protective role of SGR in heart injury of SCM was investigated and its underlying action of mechanism was explored. Firstly, the mouse and cardiomyocytes (H9C2 cell) SCM model induced by LPS were established to evaluate the therapeutic effect of SGR. The in vivo results exhibited that SGR rescued the survival rate of SCM mice, restored the loss of ejection fraction (EF) and fractional shortening (FS), and reduced left ventricular systolic diameter and left ventricular diastole diameter (LVIDs, LVIDd) by echocardiography. SGR improved the mitochondrial biosynthesis and myocardial fiber structure and arranged them neatly by transmission electron microscope (TEM). Further, SGR inhibited inflammatory targets myeloperoxidase (MPO) and tumor necrosis factor (TNF-α), interleukin-1ß (IL-1ß), interleukin-6 (IL-6), and plasminogen activator inhibitor-1 (PAI-1). And SGR activated the mitochondrial biosynthesis-related peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α), ß-catenin, and matrix metallopeptidase 2 (MMP2) proteins. Meanwhile, the in vitro results showed that SGR promoted the increased the myocardial H9C2 cell viability, and mitochondrial biosynthesis and structure. SGR also blocked the inflammatory factors and reversed PGC-1α, ß-catenin, and MMP2 in vitro, while SGR alleviated the myocardial cell apoptosis via flow cytometry. The findings indicate that SGR mitigates sepsis-caused myocardial damage by Wnt/ß-catenin signaling pathway-mediated mitochondrial biosynthesis. SGR may be a promising candidate for treatment of SCM.

Aconite aqueous extract inhibits the growth of hepatocellular carcinoma through CCL2-dependent enhancement of natural killer cell infiltration.

OBJECTIVE: Aconite is a traditional Chinese herbal medicine that has been found to inhibit the development of liver cancer; however, its exact molecular mechanisms in this process remain unclear. This study explores how aconite aqueous extract (AAE) inhibits hepatocellular carcinoma (HCC). METHODS: An in vivo mouse model of subcutaneous liver cancer was established. After AAE treatment, immunohistochemistry (IHC) was used to determine the effect of AAE on natural killer (NK) cells. Subsequently, C57BL/6 mice were used to establish the subcutaneous tumor model, and a group of these mice were treated with anti-PK163 antibody to remove NK cells, which was verified by flow cytometry and IHC. The effect of AAE on the proliferation of HCC cells in vitro was determined using cell counting kit-8. The effect of AAE on chemokine production in HCC cells was measured using real-time quantitative polymerase chain reaction and an enzyme-linked immunosorbent assay. The effect of AAE on the migration of NK cells was determined using a transwell assay. Finally, the molecular mechanism was investigated using the Western blotting method. RESULTS: We demonstrated that the ability of AAE to induce overexpression of the cytokine C-C motif chemokine ligand 2 (CCL2) in HCC cells is fundamental to the infiltration of NK cells into the tumor bed. Mechanistically, we found that the upregulation of CCL2 was achieved by the activation of c-Jun N-terminal kinase but not extracellular regulated protein kinase or p38. CONCLUSION: Our findings suggest that AAE can be used as an effective immune adjuvant to enhance antitumor immunity by increasing NK cell infiltration into tumors, which could help to improve the efficacy of HCC treatments.

Virome Analysis of Aconitum carmichaelii Reveals Infection by Eleven Viruses, including Two Potentially New Species.

Aconitum carmichaelii is a herbaceous herb indigenous to China that has been cultivated for traditional medicine for centuries. Virus-like symptoms of A. carmichaelii plants were observed on leaves in some A. carmichaelii plantations in Zhanyi and Wuding Counties, Yunnan Province, southwest China. High-throughput sequencing (HTS) was performed on 28 symptomatic plants, and the results revealed infection with 11 viruses, including 2 novel viruses and 9 previously described viruses: Aconitum amalgavirus 1 (AcoAV-1), aconite virus A (AcVA), cucumber mosaic virus (CMV), currant latent virus (CuLV), apple stem grooving virus (ASGV), chilli veinal mottle virus (ChiVMV), tomato spotted wilt orthotospovirus (TSWV), tobacco vein distorting virus (TVDV), and potato leafroll virus (PLRV). Two novel viruses tentatively named Aconitum potyvirus 1 and Aconitum betapartitivirus 1, were supported by sequence and phylogenetic analysis results of their genomes. We proposed the names Potyvirus aconiti and Betapartitivirus aconiti. RT-PCR assays of 142 plants revealed the predominance and widespread distribution of CMV, AcVA, and AcoPV-1 in plantations. The detection of isolates of CuLV, ASGV, ChiVMV, TSWV, TVDV, and PLRV infections for the first time in A. carmichaelii expands their known host ranges.

Study on the Difference of Protective Efficacy and Mechanism of Radix Aconiti Coreani and Rhizoma Typhonii in Gerbils with Ischemic Stroke.

Ischemic stroke is a common type of stroke, but effective treatment methods are still imperfect and new effective therapies need to be explored. Radix Aconiti Coreani and Rhizoma Typhonii used as Baifuzi in the treatment of stroke or symptoms associated with stroke have been recorded in ancient Chinese books and are widely used. Modern pharmacological studies have demonstrated that both of them have antioxidant and anti-inflammatory effects. The purpose of this study is to investigate whether Radix Aconiti Coreani and Rhizoma Typhonii have therapeutical effects on gerbils with ischemic stroke, to investigate their potential mechanisms of action, and to provide a reference for rational clinical application by comparing the differences between them. In this manuscript, the right unilateral ligation of the carotid artery of gerbils was used to cause an ischemic stroke model. The neurological deficits of gerbils in each group were scored by Longa scale. The area of cerebral infarction was detected by 2,3,5-tribenzotetrazolchloride staining. The levels of inflammatory factors, oxidative stress indexes, and vascular endothelial function indexes in brain homogenate and serum were determined by ELISA. The expression levels of P-Akt PI3K, HO-1, and KEAP1 proteins in brain tissue were determined by Western blot. Immunofluorescence staining was used to observe the recovery of neuronal cells in the hippocampal CA1 region of the gerbil brain tissue and the expression of proteins related to PI3K/Akt and KEAP1/Nrf2 signaling pathways in neuronal cells in the hippocampal CA1 region. It was found that Radix Aconiti Coreani and Rhizoma Typhonii could improve neurological deficits and reduce cerebral infarction rate in gerbils. The results showed that Radix Aconiti Coreani and Rhizoma Typhonii could significantly decrease the expression of inflammatory factors, increase the expression of antioxidative stress indexes and vascular endothelial function factors, activate the PI3K/Akt, KEAP1/Nrf2 signaling pathway, reduce the inflammatory response, inhibit the oxidative stress, enhance the vascular endothelial cell function, and thus protect against ischemic brain injury. From the experimental results, both Radix Aconiti Coreani and Rhizoma Typhonii had neuroprotective effects on ischemic brain injury. Compared with Rhizoma Typhonii, the effects of Radix Aconiti Coreani on anti-inflammatory and antioxidative stress were more significant, while Rhizoma Typhonii had showed more significant effects in promoting angiogenesis after ischemic stroke by increasing the level of NO.

The Role of Cancer and Somatic Stem Cells in the Anti-Inflammatory and Antitumor Effects of Aconitum baicalense Extract on Experimental Breast Cancer.

We studied the effects of the extract of the terrestrial part of Aconitum baicalense in BALB/c female mice at the early stages after the injection of N-methyl-N-nitrosourea (MNU). The extract reduced inflammatory activity and tumor growth in the mammary gland. The antitumor and anti-inflammatory effects of the extract are based on the inhibition of cancer stem cells, hematopoietic stem cells, and hematopoietic progenitor cells that promote inflammation. The extract of A. baicalense disrupted the recruitment of epithelial progenitor cells and angiogenesis precursors to the mammary gland preventing neovascularization and transformation of epithelial cells into tumor cells.
