Abstract
OBJECTIVE To explore the effects of matrine on the proliferation, tumor cell stemness, β-catenin transcriptional activity and AKT/GSK3β/β-catenin signaling pathway in human hepatocellular carcinoma (HCC) HepG2 and Huh7 cells. METHODS The proliferation and colony formation ability of HepG2 and Huh7 cells treated with 200, 400, and 800 μg/mL matrine were evaluated with MTT assay and colony formation assay, respectively. Real-time quantitative PCR was performed to detect the mRNA expressions of CD90, epithelial cell adhesion molecule (EpCAM) and CD133, and dual-luciferase assay was used to detect the transcriptional activity of β-catenin in the treated cells. The effects of matrine on the expressions of protein kinase B (AKT), P-AKT, GSK-3β, P-GSK-3β, P-β-catenin and β-catenin proteins in the Wnt/β-catenin signaling pathway were assessed using Western blotting. RESULTS Matrine inhibited the proliferation of the two HCC cell lines in a time- and concentration-dependent manner. The half-inhibitory concentrations of matrine were 2369, 1565 and 909.1 μg/mL at 24, 48 and 72 h in HepG2 cells, respectively, and were 1355, 781.8, and 612.8 μg/mL in Huh7 cells, respectively. Matrine concentrationdependently suppressed colony formation of the HCC cells, producing significant inhibitory effects at 400 μg/mL P < 0.01) and 800 μg/mL P < 0.001) in HepG2 cells and at 200 μg/mL P < 0.05), 400 μg/mL P < 0.01), and 800 μg/mL P < 0.001) in Huh7 cells. Matrine at 400 and 800 μg/mL significantly inhibited the mRNA expression of CD90, EpCAM and CD133 and the transcriptional level of β-catenin in both HepG2 and Huh7 cells P < 0.05 or 0.01). Matrine at 400 and 800 μg/mL also significantly decreased the protein levels of β-catenin, P-AKT and P-GSK-3β and increased the phosphorylation level of β-catenin in both of the cell lines. CONCLUSIONS Matrine inhibits the proliferation, colony formation, and the expressions of tumor stem cell markers CD90, EpCAM and CD133 in both HepG2 and Huh7 cells probably by inhibiting Wnt/β-catenin signaling pathway and the transcriptional activity ofβ-catenin.

[PMID: 31781324 PMCID: PMC6875205 DOI: 10.1155/2019/1709718] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Revised: 08/30/2019] [Accepted: 09/21/2019] [Indexed: 01/07/2023]
Abstract
Objective To observe whether metformin (MET) plays a protective role in acute lung injury (ALI) induced by paraquat (PQ) poisoning in rats by activating the AMPK/NF-κB signaling pathway. Methods PQ exposure was used to construct a rat model of ALI and a model of acute type II alveolar epithelial cell (RLE-6TN) injury, and MET intervention was performed. Rat lung tissue samples were collected to evaluate pathological changes in rat lung tissue, the oxidation index, and inflammatory factors; cell viability was detected by CCK-8 assays, and the protein expression levels of phospho-AMPK and phospho-NF-κBp65 in rat lung tissue and RLE-6TN cells were observed by Western blotting. Results Compared with the PQ group, the MET treatment group showed significantly (1) reduced lung wet/dry ratio (W/D: 4.67 ± 0.31 vs. 5.45 ± 0.40, P < 0.001), (2) reduced pathological changes in lung tissue, (3) decreased MDA levels (nmol/mg prot: 2.70 ± 0.19 vs. 3.08 ± 0.15, P < 0.001) and increased SOD and GSH-Px activities (U/mg prot: 76.17 ± 5.22 vs. 45.23 ± 6.58, 30.40 ± 2.84 vs. 21.00 ± 3.20; all P < 0.001) in lung tissue homogenate, (4) reduced levels of IL-1β, IL-6, and TNF-α in lung tissue homogenates (pg/mL: 47.87 ± 5.06 vs. 66.77 ± 6.55; 93.03 ± 7.41 vs. 107.39 ± 9.81; 75.73 ± 6.08 vs. 89.12 ± 8.94; all P < 0.001), (5) increased activity of RLE-6TN cells (%: 0.69 ± 0.09, 0.76 ± 0.06, and 0.58 ± 0.03 vs. 0.50 ± 0.05; all P < 0.05), (6) decreased protein levels of phospho-NF-κBp65 in lung homogenates and RLE-6TN cells (p-NF-κB/NF-κB: 0.47 ± 0.09 vs. 0.81 ± 0.13; 0.26 ± 0.07 vs. 0.79 ± 0.13; all P < 0.01), and (7) upregulated protein expression of phospho-AMPK in lung homogenates and RLE-6TN cells (p-AMPK/AMPK: 0.88 ± 0.05 vs. 0.36 ± 0.12; 0.93 ± 0.03 vs. 0.56 ± 0.15; all P < 0.01). After the addition of the AMPK inhibitor Compound C (Com C), the protein expression levels of phospho-AMPK and phospho-NF-κBp65 returned to baseline. Conclusion MET can effectively alleviate ALI induced by paraquat poisoning and increase the viability of cells exposed to paraquat. The mechanism may be related to the activation of the AMPK/NF-κB pathway, downregulation of inflammatory mediators such as IL-6 and TNF-α, and upregulation of the SOD and GSH-Px oxidation index, and these effects can be inhibited by the AMPK inhibitor Com C.

Abstract
BACKGROUND In this experimental study, we aimed to investigate the effects of hesperetin, a natural flavonoid, on a lipopolysaccharideinduced acute lung injury model in rats. METHODS Between March 2019 and May 2019, a total of 18 adult male Wistar albino rats, weighing approximately 250 to 300 g, were randomly divided into three groups as control, lipopolysaccharide, and lipopolysaccharide + hesperetin groups (n=6 in each group). The wet/dry weight ratio of lung tissue was determined. Histopathological changes were examined using light and scanning electron microscopy. Pulmonary nuclear factor-kappa beta, inducible nitric oxide synthase, and alpha-smooth muscle antigen activity were determined with indirect immunohistochemical methods. Pulmonary apoptosis was detected with the terminal deoxynucleotidyl transferase dUTP nick-end labeling method. Tumor necrosis factor-alpha, interleukin-1 beta, interleukin-6, and interleukin-10 concentrations were measured with enzyme-linked immunosorbent assay. RESULTS Treatment with hesperetin significantly improved the architecture of lung tissue and reduced the wet/dry weight ratio, nuclear factor-kappa beta, inducible nitric oxide synthase, and alphasmooth muscle antigen expression, pulmonary apoptosis, and levels of proinflammatory cytokines. CONCLUSION Our study results suggest that hesperetin has a potent protective effect against lipopolysaccharide-induced acute lung injury in rats via suppression of the proinflammatory cytokine cascade, nuclear factor-kappa beta, signaling pathway activation, and apoptosis.

Abstract
Acute lung injury (ALI) is a major cause of morbidity and mortality globally, and is characterized by widespread inflammation in the lungs. Increased production of reactive oxygen species is hypothesized to be associated with ALI. Matrine and lycopene are active products present in traditional Chinese medicine. Matrine is an effective inhibitor of inflammation, whereas lycopene decreases lipid peroxidation. Therefore, it was hypothesized that combinatorial treatment with matrine and lycopene may provide synergistic protection against ALI. In the present study, mice were treated with dexamethasone (DEX; 5 mg/kg), matrine (25 mg/kg), lycopene (100 mg/kg), and matrine (25 mg/kg) + lycopene (100 mg/kg) for 7 days prior to injury induction using lipopolysaccharide (LPS; 5 mg/kg) for 6 h. Lung tissues were collected following the sacrifice of the mice and hematoxylin and eosin staining was used for histological analysis. Malondialdehyde (MDA), glutathione (GSH) and myeloperoxidas (MPO) levels were examined by respective kits. The expressions of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were evaluated by ELISA. The expressions of IκBα and NF-κB p65 were examined by reverse transcription-quantitative polymerase chain reaction, western blotting and immunohistochemistry. The results indicated that the combined treatment exhibited a similar effect to DEX, both of which attenuated lung structural injuries, downregulated the expressions of IL-6, TNF-α, MPO and MDA, and upregulated that of GSH. Furthermore, the combined treatment and DEX inhibited NF-κB p65 activation. The present study revealed that combined treatment with matrine and lycopene exhibited protective effects on an LPS-induced mouse model of ALI, suggesting that they may serve as a potential alternative to glucocorticoid therapy for ALI.

Matrine Protects Against MCD-Induced Development of NASH via Upregulating HSP72 and Downregulating mTOR in a Manner Distinctive From Metformin. Front Pharmacol 2019; 10:405.

Abstract
The present study investigated the effects of matrine on non-alcoholic steatohepatitis (NASH) in mice induced by a methionine choline-deficient (MCD) diet and the mechanism involved. The study was performed in C57B/6J mice fed a MCD diet for 6 weeks to induce NASH with or without the treatment of matrine (100 mg/kg/day in diet). Metformin was used (250 mg/kg/day in diet) as a comparator for mechanistic investigation. Administration of matrine significantly reduced MCD-induced elevations in plasma ALT and AST but without changing body or liver fat content. Along with alleviating liver injury, matrine suppressed MCD-induced hepatic inflammation (indicated by TNFα, CD68, MCP-1, and NLRP3) and fibrosis (indicated by collagen 1, TGFβ, Smad3, and sirius-red staining). In comparison, metformin treatment did not show any clear sign of effects on these parameters indicative of NASH. Further examination of the liver showed that matrine treatment rescued the suppressed HSP72 (a chaperon protein against cytotoxicity) and blocked the induction of mTOR (a key protein in a stress pathway). In keeping with the lack of the improvement of the NASH features, metformin did not show any significant effect against MCD-induced changes in HSP72 and mTOR. Matrine protects against MCD-induced development of NASH which is refractory to metformin treatment. Its anti-NASH effects involve enhancing HSP72 and downregulating mTOR but do not rely on amelioration of hepatosteatosis.

Abstract
Endometritis is one of the main diseases that causes great economic losses in the dairy industry. Recent studies have shown that matrine extracted from the traditional Chinese herb Sophora flavescens is an alkaloid with a broad range of bioactivities. Here, we aimed to investigate the protective effects of matrine on Staphylococcus aureus lipoteichoic acid (LTA)-induced endometritis in mice and elucidate the possible molecular mechanisms in vitro. Histopathological changes showed that matrine remarkably attenuated the uterus injury in a mouse model of LTA-induced endometritis. qPCR and ELISA results showed that matrine dose-dependently reduced the expression of pro-inflammatory cytokines (TNF-α and IL-1β). To further elucidate the underlying mechanisms of this protective effect of matrine, LTA-stimulated bovine endometrial epithelial cells (bEECs) were employed in this study. The results demonstrated that TLR2 expression and its downstream nuclear factor (NF)-κB activation were both suppressed by matrine treatment. Furthermore, a small interference RNA targeting TLR2 gene mimicked matrine in its inhibition on LTA-induced activation of TLR2 and NF-κB. In conclusion, these findings suggest the protective effect of matrine against LTA-induced endometritis through negative regulation of TLR2-mediated NF-κB pathway.

Matrine reduces cigarette smoke-induced airway neutrophilic inflammation by enhancing neutrophil apoptosis. Clin Sci (Lond) 2019; 133:551-564.

Abstract
Chronic Obstructive Pulmonary Disease (COPD) is a major incurable global health burden and will become the third largest cause of death in the world by 2030. It is well established that an exaggerated inflammatory and oxidative stress response to cigarette smoke (CS) leads to, emphysema, small airway fibrosis, mucus hypersecretion, and progressive airflow limitation. Current treatments have limited efficacy in inhibiting chronic inflammation and consequently do not reverse the pathology that initiates and drives the long-term progression of disease. In particular, there are no effective therapeutics that target neutrophilic inflammation in COPD, which is known to cause tissue damage by degranulation of a suite of proteolytic enzymes including neutrophil elastase (NE). Matrine, an alkaloid compound extracted from Sophora flavescens Ait, has well known anti-inflammatory activity. Therefore, the aim of the present study was to investigate whether matrine could inhibit CS-induced lung inflammation in mice. Matrine significantly reduced CS-induced bronchoalveolar lavage fluid (BALF) neutrophilia and NE activity in mice. The reduction in BALF neutrophils in CS-exposed mice by matrine was not due to reductions in pro-neutrophil cytokines/chemokines, but rather matrine's ability to cause apoptosis of neutrophils, which we demonstrated ex vivo Thus, our data suggest that matrine has anti-inflammatory actions that could be of therapeutic potential in treating CS-induced lung inflammation observed in COPD.

Abstract
Acute lung injury (ALI) is served as a severe life-threatening disease. However, the pathogenesis that contributes to ALI has not been fully understood. Tumor necrosis factor receptor-associated factor 1 (TRAF1) interacts with multiple regulators, performing its diverse role in biological functions. However, the effects of TRAF1 on ALI remain unknown. In this study, we attempted to explore the role of TRAF1 in ALI progression. The findings suggested that TRAF1-knockout (KO) markedly attenuated LPS-induced severe mortality rate in murine animals. LPS-elicited histological alterations in pulmonary tissues were significantly alleviated by TRAF1-deletion. Additionally, TRAF1 knockout effectively attenuated lung injury, as evidenced by the reduced lung wet/dry (W/D) weight ratio, as well as decreased bronchoalveolar lavage fluid (BALF) protein levels and neutrophil infiltration. Meanwhile, TRAF1 deletion markedly lessened inflammation, oxidative stress and apoptosis in BALF and/or lung tissues. The levels of pro-inflammatory cytokines stimulated by LPS were down-regulated by TRAF1 ablation, along with the inactivation of nuclear factor κB (NF-κB). LPS-promoted reactive oxygen species (ROS) generation was decreased in TRAF1-KO mice, partly through the improvement of anti-oxidants. Apoptosis was also inhibited by TRAF1 deletion in lung tissues of LPS-challenged mice through the suppression of cleaved Caspase-3. Moreover, TRAF1 knockout significantly decreased c-Jun N-terminal kinase (JNK) activation and its down-streaming signal of c-Jun in pulmonary samples of LPS-induced mice. Importantly, the in vitro study suggested that promoting JNK activation markedly abrogated TRAF1 knockdown-attenuated inflammation, ROS production and apoptosis in LPS-exposed A549 cells. Therefore, our experimental results provided evidence that TRAF1 suppression effectively protected LPS-induced ALI against inflammation, oxidative stress and apoptosis through the suppression of JNK activity.

Abstract
Acute lung injury (ALI) is a common clinical syndrome in ICU departments with high mortality. The pathology of ALI is still not clear and there is no specific and efficient treatment against ALI. In this study, we established ALI rat model through lipopolysaccharide administration. We found that hypothermia therapy led to significant improvement in oxygenation index, edema formation and pathological score, demonstrating that hypothermia is beneficial to the recovery of lung function and alleviation of lung injury. Besides, hypothermia resulted in a decrease in plasminogen activator inhibitor-1(PAI-1) concentration, showing the inflammation was partially inhibited. This was also confirmed by a decrease in TNF-α mRNA and protein level in hypothermia group. The effect of hypothermia was mediated by TLR2/MyD88 signaling, which led to the alteration in NF-κB p65 level. Collectively, this study indicated that hypothermia therapy was potentially an efficient therapy against ALI.

Abstract
To discover new natural-product-based potential pesticides, 85 matrinic acid/alcohol/ester derivatives were synthesized by structural modifications of a quinolizidine alkaloid matrine. N-(4-Methyl)benzylmatrinyl n-decylate (76) and N-(2-chloro)benzylmatrinyl n-undecylate (86) exhibited greater than seven-fold more pronounced acaricidal activity than matrine against Tetranychus cinnabarinus; N-(2-chloro)benzylmatrinyl benzoate (80) showed the most promising insecticidal activity against Mythimna separata. The carboxyl group of matrinic acids and introduction of n-decyl/ n-undecylcarbonyl into matrinic alcohols were important for the acaricidal activity; introduction of alkyloxy into the carboxyl of matrinic acids and introduction of the electron-withdrawing groups on the N-benzyl of matrinic esters were necessary for the insecticidal activity. Through RT-PCR and qRT-PCR analysis, it was shown that the lactam ring of matrine was vital for action on VGSC; opening the lactam ring of matrine and the alkylcarbonyl of side-chain were two important factors for acting with α1, α2, and α4 nAChR subunits; α1, α2, α4, and β3 subunits may be the target of action of compound 86 against T. cinnabarinus.

Amelioration of Lipopolysaccharide-Induced Acute Lung Injury in Rats by Na-H Exchanger-1 Inhibitor Amiloride Is Associated with Reversal of ERK Mitogen-Activated Protein Kinase. BIOMED RESEARCH INTERNATIONAL 2018; 2018:3560234. [PMID: 30627552 PMCID: PMC6304609 DOI: 10.1155/2018/3560234] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/04/2018] [Accepted: 11/27/2018] [Indexed: 12/15/2022]
Abstract
Background Na-H exchanger-1 (NHE-1) is expressed in the lung of rats. Accumulating evidence shows that Na-H exchangers are involved in inflammation. Amiloride, an inhibitor of NHE-1, inhibits the activation of macrophages and endothelial cells and reduces their production of cytokines. Since these processes have been implicated in acute lung injury (ALI) induced by lipopolysaccharide (LPS), we examined the protective effect of amiloride on ALI induced by LPS in rats. Material and Methods ALI in specific pathogen-free male Sprague-Dawley rats was induced by an intravenous injection of 6 mg/kg LPS. Amiloride pretreated rats received an intravenous injection of 10 mg/kg amiloride 30 min before the administration of LPS. Controls received normal saline in a similar manner. All animals were sacrificed 6 h after LPS or normal saline administration. The degree of ALI was assessed by wet-to-dry weight ratio (W/D) and lung histological examination. Neutrophilic infiltration was determined by myeloperoxidase (MPO) activity in lung tissue. Concentrations of total protein (TP), tumor necrosis factor-alpha (TNF-α), and macrophage inflammatory protein-2 (MIP-2) in bronchoalveolar lavage fluid (BALF) were also measured. Expression of NHE-1 and mitogen-activated protein kinase (MAPK) p38, p-p38, ERK, and p-ERK was evaluated by western blot analysis. Results Pretreatment with amiloride significantly reduced the increase in W/D, ALI score, lung tissue MPO activity, concentrations of TP, TNF-α, and MIP-2 in BALF, resulting in attenuation of ALI induced by LPS. Meanwhile, levels of NHE-1 and p-ERK proteins were reversed, whereas that of p-p38 was not. Conclusions These findings suggest that NHE-1 inhibitor amiloride could attenuate ALI induced by LPS in rats. This effect is mediated through reversal of ERK.

Abstract
BACKGROUND Acute lung injury (ALI) is a type of severe pulmonary inflammatory disease with high rates of morbidity and mortality. Now, an increasing number of studies suggest that lncRNAs may act as key regulators of the inflammatory response and play a crucial role in the pathogenesis of many inflammatory diseases. Our study firstly explored the function and underlying mechanism of lncRNA metastasis-associated lung adenocarcinoma transcription 1 (MALAT1) in regulating the inflammatory response of lipopolysaccharide (LPS)-induced ALI in rats. METHODS The ALI rats were constructed by intratracheal instillation with LPS. Hematoxylin and eosin (HE) for histological examination were performed to detect histopathological changes in the lung tissues. Enzyme-linked immunosorbent assay (ELISA) was used to determine the concentrations of cytokines TNF-α, IL-6, and IL-1β in the supernatants of the bronchoalveolar lavage fluid (BALF). Quantitative real-time PCR (qRT-PCR) analysis was employed to assess the expression of MALAT1, miR-146a, TNF-α, IL-6, and IL-1β in lung tissues. Luciferase reporter assay and RNA immunoprecipitation (RIP) assay were used to detect the relationship between MALAT1 and miR-146a. RESULTS The results revealed that MALAT1 knockdown played a protective role in the LPS-induced ALI rat model. In addition, knockdown of MALAT1 in vitro inhibited LPS-induced inflammatory response in murine alveolar macrophages cell line MH-S and murine alveolar epithelial cell line MLE-12. This study found that MALAT1 acts as a molecular sponge for miR-146a and MALAT1 negatively regulated miR-146a expression. Mechanistically, MALAT1 overexpression alleviated the inhibitory effect of miR-146a on LPS-induced inflammatory response in MH-S. CONCLUSIONS Together, our study provided the first evidence that MALAT1 knockdown could suppress inflammatory response by up-regulating miR-146a in LPS-induced ALI, which provided a potential therapeutic target for the treatment of ALI.

Abstract
Aim: Acute lung injury is a common clinical syndrome associated with significant morbidity. Myricetin has been demonstrated to inhibit inflammation in a variety of diseases. In this study, we aimed to investigate the protective effects of myricetin on inflammation in lipopolysaccharide-stimulated RAW 264.7 cells and lipopolysaccharide-induced lung injury model. Results/methodology: In this study, we detected the anti-inflammatory effects of myricetin by ELISA, RT-PCR and Western blot, respectively. Myricetin significantly inhibited the production of the proinflammatory cytokines in vitro and in vivo. It exerted an anti-inflammatory effect through suppressing the NF-κB p65 and AKT activation in NF-κB pathway and JNK, p-ERK and p38 in MAPK signaling pathway. Conclusion: Myricetin alleviated acute lung injury by inhibiting macrophage activation, and inhibited inflammation in vitro and in vivo. It may be a potential therapeutic candidate for the prevention of inflammatory diseases.

Abstract
Lipopolysaccharide (LPS)-induced inflammation occurs commonly and volatile oil from Angelica sinensis (VOAS) can be used as an anti-inflammatory agent. The molecular mechanisms that allow the anti-inflammatory factors to be expressed are still unknown. In this paper, we applied gas chromatography-mass spectrometry (GC-MS) and high-performance liquid chromatography-time-of-flight mass spectrometry (LC-Q/TOF-MS) based on a metabolomics platform coupled with a network approach to analyze urine samples in three groups of rats: one with LPS-induced inflammation (MI); one with intervention with VOAS; and normal controls (NC). Our study found definite metabolic footprints of inflammation and showed that all three groups of rats, MI, intervention with VOAS and NC have distinct metabolic profiles in urine. The concentrations of 48 metabolites differed significantly among the three groups. The metabolites in urine were screened by the GC-MS and LC-Q/TOF-MS methods. The significantly changed metabolites (p < 0.05, variable importance in projection > 1.5) between MI, NC and VOAS were included in the metabolic networks. Finally, hub metabolites were screened, including glycine, arachidonic acid, l-glutamate, pyruvate and succinate, which have high values of degree (k). the Results suggest that disorders of glycine, arachidonic acid, l-glutamate, pyruvate and succinate metabolism might play an important part in the predisposition and development of LPS-induced inflammation. By applying metabolomics with network methods, the mechanisms of diseases are clearly elucidated.

Abstract
Acute lung injury (ALI), known a severe disease along with high morbidity and mortality, is lacking of specific therapies. Inflammation, apoptosis and oxidative stress are critical pathologies that contribute to ALI. Recently, there is study indicated that NLRP9b, a NOD-like receptor (NLR) member, is critical in modulation of inflammatory response. However, the effects of NLRP9b on sepsis-associated ALI, and the underlying molecular mechanism have not been understood. In the present study, the wild type (WT) and NLRP9b-knockout (NLRP9b-/-) mice with C57B/L6 background were subjected to a cecal ligation and puncture (CLP) for ALI murine model establishment. The findings indicated that NLRP9b-/- improved the survival rate of CLP-induced ALI mice, and inhibited pulmonary histopathological alterations, inflammation, and apoptosis. NLRP9b-/- reduced the activation of inhibitor of κBα/nuclear factor kappa B (IκBα/NF-κB), apoptosis-associated speck-like protein containing a Caspase-recruitment domain (ASC)/Casapse-1 and Caspase-3/poly (ADP-ribose) polymerase (PARP) signaling pathways in CLP-challenged mice with ALI. In vitro, mouse epithelial cells (MLE-12) were incubated with lipopolysaccharide (LPS) or recombinant NLRP9b caused a significant increased of pro-inflammatory cytokines or chemokine, and reactive oxygen species (ROS) generation; however, these changes were markedly alleviated by NLRP9-knockdown using its specific siRNA sequence. Pre-treatment of MLE-12 cells with ROS scavenger of N-acetylcysteine (NAC) remarkably decreased lipopolysaccharide (LPS)- and rMuNLRP9-induced production of ROS, and the secretion of inflammatory cytokines or chemokine, as well as the activity of IκBα/NF-κB, ASC/Casapse-1 and Caspase-3/PARP signaling pathways. Together, the findings here suggested that NLRP9b played an essential role in lung inflammation, apoptosis and oxidative stress of sepsis-induced ALI animal model or in LPS-induced MLE-12 cells, providing that NLRP9b inhibition might be a potential therapeutic option for ALI.

Abstract
Matrine, one of the main alkaloid components extracted from the traditional Chinese herb, Sophora flavescens Ait, has various pharmacological effects, and has been reported to exert antitumor activity in melanoma. In the current study, the molecular mechanisms underlying the inhibitory effects of matrine were investigated in melanoma cell line. It was initially confirmed that matrine inhibited proliferation, invasion and induced apoptosis in human A375 and SK-MEL-2 melanoma cell lines in vitro. Subsequently, reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis demonstrated that the expression of microRNA (miR)-19b-3p was significantly increased in melanoma cells and was downregulated by treatment with matrine. Furthermore, downregulated miR-19b-3p exerted effects similar to 500 µg/ml matrine on cell proliferation, invasion and apoptosis. Phosphatase and tensin homolog (PTEN) mRNA was identified as a direct target of miR-19b-3p through bioinformatics analysis and a dual-luciferase reporter assay. Additionally, western blotting and RT-qPCR analysis demonstrated that the expression of PTEN protein and mRNA were increased by the treatment with matrine. Furthermore, silencing of PTEN expression reversed the effects of matrine and miR-19b-3p downregulation in A375 and SK-MEL-2 cells. Taken together, the results indicated that matrine may suppress cell proliferation and invasion and induce cell apoptosis partially via miR-19b-3p targeting of PTEN.

Abstract
After spinal cord injury (SCI), reconstruction of neuronal tracts is very difficult because an inhibitory scar is formed at the lesion site, in which several axonal growth inhibitors, such as chondroitin sulfate proteoglycans (CSPG), accumulate. We previously found that matrine, a major alkaloid in Sophora flavescens, enhanced axonal growth in neurons seeded on CSPG coating. The aims of this study were to investigate therapeutic effects of matrine in SCI mice and to clarify the underlying mechanism. Matrine was orally administered to contusion SCI mice. In the matrine-treated mice, motor dysfunction of the hindlimbs was improved, and the density of 5-HT-positive tracts was increased in the injured spinal cord. We explored putative direct binding proteins of matrine in cultured neurons using drug affinity responsive target stability (DARTS). As a result, heat shock protein 90 (HSP90) was identified, and matrine enhanced HSP90 chaperon activity. We then presumed that extracellular HSP90 is a matrine-targeting signaling molecule, and found that specific blocking of extracellular HSP90 by a neutralizing antibody completely diminished matrine-induced axonal growth and SCI amelioration. Our results suggest that matrine enhances axonal growth and functional recovery in SCI mice by direct activation of extracellular HSP90. Matrine could be a significant candidate for therapeutic drugs for SCI with a novel mechanism.

Abstract
Chronic osteomyelitis is primarily caused by infection with Staphylococcus aureus (S. aureus). Antibiotics are commonly administered; however, it is a challenge to promote bone healing. The aim of this study was to investigate the in vitro effects of alkaloids from the herbal remedy Sophora flavescens (ASF) on rat calvarial osteoblasts (ROBs) infected with S. aureus and healthy osteoclasts. Cell proliferation and alkaline phosphatase, interleukin-6, and tumour necrosis factor-α activity was measured in infected ROBs; tartrate-resistant acid phosphatase was evaluated in osteoclasts via enzyme-linked immunosorbent assay. The mRNA and protein expression levels of bone morphogenetic protein 2, runt-related transcription factor 2, osteoprotegerin, and receptor activator of nuclear factor kappa-B ligand were assessed in infected ROBs through reverse transcription-polymerase chain reaction and western blotting analysis, respectively. Results indicated that ASF increased the viability of uninfected ROBs and infected ROBs treated with vancomycin via regulation of bone morphogenetic protein 2, runt-related transcription factor, osteoprotegerin, and receptor activator of nuclear factor kappa-B ligand mRNA and protein expression levels. In addition, the secretion of the inflammatory factor tumour necrosis factor-α was decreased and alkaline phosphatase activity was increased, inhibiting the viability of osteoclasts and tartrate-resistant acid phosphatase activity. Therefore, the herbal remedy ASF has potential as a new treatment for chronic osteomyelitis.

Abstract
Bioavailable and less toxic synthetic retinoids, such as the atypical adamantyl retinoid ST1926, have been well developed and investigated in clinical trials for many diseases. The aim of our study was to explore the role of ST1926 in lipopolysaccharide (LPS)-induced acute lung injury (ALI) and to reveal the possible molecular mechanism. Mice were treated with LPS to induce acute lung injury followed by ST1926 administration. After LPS induction, mice administered with ST1926 showed lower inflammation infiltration in bronchoalveolar lavage (BAL) fluid, and pro-inflammatory cytokines, including interleukin-1β (IL-1β), IL-18, IL-6 and tumor necrosis factor-α (TNF-α) in serum and lung tissue samples obtained from mice. In addition, western blot assays suggested that ST1926 suppressed nuclear factor-κB (NF-κB), inhibitor-κB kinase-α (IκBα) and IκB kinase (IKKα), as well as Toll-like receptor 4 (TLR4) induced by LPS. In addition, reactive oxygen species (ROS) stimulated by LPS was also suppressed for ST1926 through inhibiting p38 and extracellular receptor kinase (ERK) signaling pathway. Taken together, the data here indicated that ST1926 may be of potential value in treating acute lung injury through inflammation and ROS suppression via inactivating TLR4/NF-κB and p38/ERK1/2 signaling pathways.

Abstract
The eradication of cancer stem cells (CSCs) is significant for cancer therapy and prevention. In this study, we evaluated WM130, a novel derivative of matrine, for its effect on CSCs using human hepatocellular carcinoma (HCC) cell lines, their sphere cells, and sorted EpCAM+ cells. We revealed that WM130 could not only inhibit proliferation and colony formation of HCC cells, but also suppress the expression of some stemness-related genes and up-regulate some mature hepatocyte marker genes, indicating a promotion of differentiation from CSCs to hepatocytes. WM130 also suppressed the proliferation of doxorubicin-resistant hepatoma cells, and markedly reduced the cells with CSC biomarker EpCAM. Moreover, WM130 suppressed HCC spheres, not only primary spheres but also subsequent spheres, indicating an inhibitory effect on self-renewal capability of CSCs. Interestingly, WM130 exhibited a remarkable inhibitory preference on HCC spheres and EpCAM+ cells rather than their parental HCC cells and EpCAM- cells respectively. In vivo, WM130 inhibited HCC xenograft growth, decreased the number of sphere-forming cells, and remarkably decreased the levels of EpCAM mRNA and protein in tumor xenografts. Better inhibitory effect was achieved by WM130 in combination with doxorubicin. Further mechanism study revealed that WM130 inhibited AKT/GSK3β/β-catenin signaling pathway. Collectively, our results suggest that WM130 remarkably inhibits hepatic CSCs, and this effect may via the down-regulation of the AKT/GSK3β/β-catenin pathway. These findings provide a strong rationale for the use of WM130 as a novel drug candidate in HCC therapy.

Abstract
Neuroblastoma is a major contributor of cancer-specific mortality. Although remarkable enhancement has been achieved in the treatment of neuroblastoma in patients with early stage disease, limited progress has been made in the treatment of patients with high-risk neuroblastoma. Thus, innovative approaches are required to achieve further improvements in neuroblastoma patient survival outcomes. The major alkaloid obtained from Sophora flavescens Ait, matrine, has been shown to counteract malignancy in various kinds of cancers. In the current study, we evaluated the effects of matrine on the migration and proliferation of neuroblastoma cells. Cell cycle analysis coupled with Transwell and wound healing experiments showed that matrine triggers G2/M cell cycle arrest and suppresses neuroblastoma migration. This effect of matrine is due to upregulation of TRB3 expression followed by inhibition of the PI3K/AKT activation. Consistent with the in vitro data, growth of xenograft cancer was also suppressed by matrine. Our results indicate that matrine inhibits neuroblastoma cell proliferation and migration by enhancing TRB3 expression, suggesting that matrine may serve as a promising agent for the treatment of neuroblastoma.

Abstract
Comprehensively understanding pharmacological functions of natural products is a key issue to be addressed for the discovery of new drugs. Unlike some single-target drugs, natural products always exert diverse therapeutic effects through acting on a "network" that consists of multiple targets, making it necessary to develop a systematic approach, e.g., network pharmacology, to reveal pharmacological functions of natural products and infer their mechanisms of action. In this work, to identify the "network target" of a natural product, we perform a functional analysis of matrine, a marketed drug in China extracted from a medical herb Ku-Shen (Radix Sophorae Flavescentis). Here, the network target of matrine was firstly predicted by drugCIPHER, a genome-wide target prediction method. Based on the network target of matrine, we performed a functional gene set enrichment analysis to computationally identify the potential pharmacological functions of matrine, most of which are supported by the literature evidence, including neurotoxicity and neuropharmacological activities of matrine. Furthermore, computational results demonstrated that matrine has the potential for the induction of macropinocytosis and the regulation of ATP metabolism. Our experimental data revealed that the large vesicles induced by matrine are consistent with the typical characteristics of macropinosome. Our verification results also suggested that matrine could decrease cellular ATP level. These findings demonstrated the availability and effectiveness of the network target strategy for identifying the comprehensive pharmacological functions of natural products.

Abstract
Sophoridine is an alkaloid extracted from Sophora alopecuroides that has extensive pharmacological actions. In the present study, the effect of sophoridine on cell growth of human medulloblastoma and its mechanism were investigated. Human medulloblastoma D283-Med cells were incubated with 0, 0.5, 1 or 2 mg/ml sophoridine for 24, 48 or 72 h. Cell proliferation and cytotoxicity were analyzed using MTT and lactate dehydrogenase assays, respectively. Next, analyses of cell apoptosis and caspase-3/8 activity were performed using flow cytometry or spectrophotometry, respectively. Lastly, the change in FoxM1, TrkB, BDNF, NF-κB and AP-1 expression was investigated using western blot analysis. In the present study, treatment with sophoridine significantly suppressed cell growth and induced apoptosis in human medulloblastoma cells. In addition, sophoridine significantly increased cytotoxicity and caspase-3/8 activity in human medulloblastoma. Finally, it was found that sophoridine suppresses the protein expression of FoxM1, TrkB, BDNF NF-κB and AP-1 in human medulloblastoma cells. The present study suggests that sophoridine suppresses cell growth of human medulloblastoma through the inhibition of the FoxM1, NF-κB and AP-1 signaling pathway.

Abstract
Acute lung injury (ALI) is a common severe clinical syndrome in intensive care unit. Inflammation has been reported to play a critical role in the development of ALI. Cordycepin, an active component isolated from Cordyceps militaris, has been reported to have anti-inflammatory effects. However, the anti-inflammatory effects of cordycepin on LPS-induced ALI remain unclear. Therefore, in the present study, we assessed whether cordycepin could attenuate ALI induced by LPS. The mice were conditioned with cordycepin 1h before intranasal instillation of LPS. Lung wet/dry (W/D) ratio, MPO activity, MDA content, and inflammatory cytokines production were detected. The expression of NF-κB p65, I-κB, Nrf2, and HO-1 were detected by western blot analysis. We found that LPS significantly increased lung wet/dry (W/D) ratio, MPO activity, MDA content, and inflammatory cytokines production. However, the increases were significantly inhibited by treatment of cordycepin. LPS-induced NF-κB activation was also suppressed by cordycepin. In addition, cordycepin was found to up-regulate the expression of Nrf2 and HO-1 in a dose-dependent manner. In conclusion, our results demonstrated that cordycepin could attenuate LPS-induced ALI effectively, probably due to inhibition of inflammation and oxidative stress.

Abstract
Artemisia argyi is used as a health supplement, tea, and food source in Korea. This study aimed to evaluate the effect of Artemisia argyi (AA) and its active compound, dehydromatricarin A (DA), on the attenuation of airway inflammation in a murine model of lipopolysaccharide (LPS)-induced acute lung injury (ALI). The C57BL/6 mice were administered AA (50 mg/kg or 100 mg/kg) and DA (10 mg/kg or 20 mg/kg) by oral gavage from day 0 to 7 days and LPS treated by intranasal instillation 48 hours before the sacrifice. The treatment of AA and DA markedly decreased inflammatory cells in the bronchoalveolar lavage fluid (BALF) compared with that in ALI-induced mice, which was accompanied by a significant reduction in the levels of tumor necrosis factor (TNF)-α and interleukin (IL)-6 in BALF. Furthermore, the administration of AA and DA clearly decreased inducible nitric oxide synthase (iNOS) expression and nuclear factor kappa B (NF-κB) phosphorylation in comparison with that in the ALI-induced mice. The histological examination of the lung tissue revealed that the administration of AA and DA suppressed the inflammatory cell infiltration into the peribronchial and alveolar lesions induced by LPS instillation. Collectively, our results indicated that AA and DA effectively decreased the airway inflammatory response induced by LPS instillation. Therefore, AA and DA may offer a potential therapy for airway inflammatory disease.

Abstract
Postmenopausal osteoporosis (POMP) is a public health problem characterized by decreased bone density and increased fracture risk. Over-activated osteoclastogenesis plays a vital role in POMP. Here we developed a novel bioactive compound MASM (M19) based on sophocarpine. Although it showed no significant effects on osteogenesis and adipogenesis for bone marrow-derived mesenchymal stem cells (BMSCs) in vitro, it could significantly inhibit RANKL/M-CSF induced osteoclastogenesis through suppressing NF-κB, MAPKs and PI3K/Akt pathways in vitro and ameliorate bone loss in ovariectomized mice in vivo. Ribosomal protein s5 (RPS5) has been identified as a target of M19 and regulates PI3K/Akt, NF-κB and MAPKs pathways in osteoclastogenesis. Overexpressions of RPS5 synergistically inhibited osteoclastogenesis with M19 while silencing RPS5 compromised M19 inhibitory effects on osteoclastogenesis in vitro. Among the three pathways, Akt plays a major role in M19 effects. The Akt activator SC79 partially reversed the inhibitory effects on osteoclastogenesis by M19 and RPS5-knocking-down. It indicates that RPS5 serves as a potential candidate target for inhibiting osteoclastogenesis and osteoporosis therapy and M19 is a promising agent for POMP treatment.

Abstract
The aim of this study was to investigate the protective effects of matrine on lipopolysaccharide (LPS)-induced inflammation and oxidative stress in vivo and in vitro. The results showed that matrine improved intestinal inflammatory status and oxidative balance and enhanced chemokine receptor 7 (CCR7) expression. In LPS-challenged mice and Caco-2 cells, matrine alleviated LPS-induced inflammation and oxidative stress via downregulating pro-inflammatory cytokines (IL-1β and IL-17) and malondialdehyde (MDA) production. CCR7-siRNA transfection blocked the protective effects of matrine on LPS-induced inflammation and oxidative stress and exacerbated LPS caused injury. In conclusion, matrine alleviates LPS-induced intestinal inflammation and oxidative stress in mice and Caco-2 cells, which may be associated with CCR7 signal.

Abstract
Osteoporosis is a metabolic bone disease characterized by decreased bone density and strength due to excessive loss of bone protein and mineral content. The imbalance between osteogenesis by osteoblasts and osteoclastogenesis by osteoclasts contributes to the pathogenesis of postmenopausal osteoporosis. Estrogen withdrawal leads to increased levels of proinflammatory cytokines. Overactivated osteoclasts by inflammation play a vital role in the imbalance. Matrine is an alkaloid found in plants from the Sophora genus with various pharmacological effects, including anti-inflammatory activity. Here we demonstrate that matrine significantly prevented ovariectomy-induced bone loss and inhibited osteoclastogenesis in vivo with decreased serum levels of TRAcp5b, TNF-α, and IL-6. In vitro matrine significantly inhibited osteoclast differentiation induced by receptor activator for NF-κB ligand (RANKL) and M-CSF in bone marrow monocytes and RAW264.7 cells as demonstrated by tartrate-resistant acid phosphatase (TRAP) staining and actin-ring formation as well as bone resorption through pit formation assays. For molecular mechanisms, matrine abrogated RANKL-induced activation of NF-κB, AKT, and MAPK pathways and suppressed osteoclastogenesis-related marker expression, including matrix metalloproteinase 9, NFATc1, TRAP, C-Src, and cathepsin K. Our study demonstrates that matrine inhibits osteoclastogenesis through modulation of multiple pathways and that matrine is a promising agent in the treatment of osteoclast-related diseases such as osteoporosis.-Chen, X., Zhi, X., Pan, P., Cui, J., Cao, L., Weng, W., Zhou, Q., Wang, L., Zhai, X.

Abstract
Silibinin, a natural product extracted from Silybum marianum (milk thistle), has been reported to have anti-inflammatory effect. The aim of this study was to explore the therapeutic effects and potential mechanisms of silibinin on lipopolysaccharide (LPS)-stimulated inflammatory responses in acute lung injury (ALI). Male BALB/c mice were conditioned with silibinin 1 h after intranasal instillation of LPS. After 12 h, the myeloperoxidase (MPO) level in lung tissues, the wet/dry (W/D) ratio, inflammatory cytokines in the bronchoalveolar lavage fluid (BALF), and histopathological examination of lung were detected. Our results showed that silibinin inhibited LPS-induced histopathological changes and MPO activity, as well as the wet/dry (W/D) ratio in the lung tissues. Furthermore, silibinin significantly inhibited LPS-induced inflammatory cytokines production in the BALF. In addition, silibinin suppressed LPS-induced NF-κB activation and the expression of NLRP3 inflammasome. These results indicate that silibinin exerts its anti-inflammatory effect by inhibiting NF-κB and NLRP3 signaling pathways.

Abstract
MASM is a matrine derivate that exhibits a number of pharmacological effects, including immunosuppressive activity and anti-inflammatory properties. In this study, the mechanisms underlying the therapeutic efficacy of MASM in the treatment of rheumatoid arthritis were investigated using DBA/1 mice with collagen-induced arthritis (CIA) and fibroblast-like synoviocytes derived from rheumatoid arthritis patients (RA-FLS). We demonstrated that MASM markedly attenuated the severity of arthritis in CIA mice. The therapeutic effects were associated with ameliorated joint swelling and reduced bone erosion and destruction. Furthermore, the administration of MASM suppressed the expression of pro-inflammatory cytokines (TNF-α, IL-1β, IL-6). In vitro, MASM inhibited the expression of pro-inflammatory cytokines (TNF-α, IL-6, IL-8) and matrix metalloproteinases (MMP-1, MMP-3 and MMP-13) by inhibiting both the phosphorylation of MAPKs and the activation of NF-κB in IL-1β-stimulated RA-FLS. Additionally, MASM could induce apoptosis of RA-FLS via mitochondrial and Akt signaling pathways in human RA-FLS. These findings suggest that MASM could attenuate arthritis severity in CIA mice at least partially by blocking the phosphorylation of MAPKs and the activation of NF-κB and by inducing apoptosis in RA-FLS. MASM could be a potent therapeutic agent for the treatment of RA.

Abstract
Oxymatrine has been shown to exert an antitumor effect on several types of cancer cells. However, the role of oxymatrine in bladder cancer has not yet been evaluated. The present study was designed to investigate the potential anti-proliferative effect of oxymatrine on bladder cancer T24 cells and the possible mechanisms involved. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was used to determine cell growth, and the cell morphology was examined using hematoxylin and eosin staining, wrights' staining and electron microscopy. The caspase-3 and survivin mRNA and protein levels were assessed using reverse transcription-quantitative polymerase chain reaction and western blot analysis, respectively. The expression of tumor protein p53 (p53), Bcl-2-associated X protein (Bax) and B-cell lymphoma 2 (Bcl-2) were analyzed using immunohistochemistry. Oxymatrine inhibited the proliferation of the T24 cells in a dose- and time-dependent manner. Oxymatrine also induced apoptosis and cell cycle arrest in the cells, in association with the upregulation of caspase-3 and Bax, and the downregulation of survivin, Bcl-2 and p53 expression. Overall, oxymatrine inhibits the proliferation of human bladder cancer cells by inducing apoptosis and cell cycle arrest via mechanisms that involve p53-Bax signaling and the downregulation of survivin expression.

Abstract
Geraniin, a typical ellagitannin isolated from Phyllanthusurinaria Linn, has been reported to have anti-inflammatory effect. The aim of the study is to investigate the therapeutic effects of geraniin on LPS-induced acute lung injury (ALI) in mice. The mice were intranasal adminisration of LPS for 12 h. Geraniin was intra-peritoneal injection 1 h after LPS treatment. The results showed that geraniin significantly attenuated LPS-induced pathological changes in the lung. Geraniin also inhibited LPS-induced macrophages and neutrophils infiltration in the lung. Geraniin significantly attenuated LPS-induced elevation of MPO level. LPS-induced TNF-α, IL-6 and IL-1β production were markedly suppressed by treatment of geraniin. Furthermore, geraniin inhibited NF-κB activation in LPS-induced ALI. In addition, geraniin was found to up-regulate the expression of Nrf2 and HO-1. In conclusion, these data suggested that geraniin had therapeutic effects in LPS-induced ALI by inhibiting NF-κB and activating Nrf2 signaling pathways.

Abstract
Multidrug resistance (MDR) is a major cause of chemotherapy failure. It occurs when an organism is resistant to one type of drug, but also develops resistance to other drugs with different structures and targets. There is a high incidence of MDR in cancer chemotherapy, therefore, finding an effective and non-toxic MDR reversal agent is an important goal, particularly for P-glycoprotein-mediated MDR in cancer. Improvements continue to be made to the status and understanding of traditional Chinese medicine (TCM), due to the advantages of low toxicity and relatively minor side effects. Therefore TCM is currently being used in the treatment of various types of diseases. In recent years, numerous components of TCM have been identified to be effective in reversing MDR by downregulating expression of the drug transporter membrane protein, recovering changes in enzymes involved in detoxification and metabolism and repairing the cell apoptosis pathway. The present study summarizes the anticancerous properties and MDR reversing components of traditional medicinal plants commonly used in the treatment of cancer.

Abstract
BACKGROUND In aging, a host of molecular and cellular changes occur which accelerate alteration and progression of inflammatory diseases. These conditions in the elderly people cause appearance of a phenomenon which has been denoted as "inflammaging". Understanding the pathogenesis and finding new methods for management of inflammaging are essential. PURPOSE In this paper we tried not only to explain inflammaging and its treatments with concentrating on medical plants but to collect a sufficient collection of anti-inflammatory plants with focusing on their mechanism of action. METHOD In this review paper, by searching in indexing cites, desired articles were obtained since 1995 by using keywords of inflammation, inflammaging, inflammation pathophysiology, free radicals and inflammation, aging inflammation, inflammatory disease, and plants or herbal medicine in inflammation. SECTIONS In advanced age the generation of free radicals increases in cardiovascular system. Pathological inflammation is also associated with production of excess free radicals More importantly, chronic inflammation makes aged people susceptible to age-related diseases. Some medicinal plants have been shown promising results in inhibition of inflammaging. Some other sections such as inflammation and inflammaging in cardiovascular diseases, oxidative stress in cardiovascular complications, prevention and treatment strategies are presented. CONCLUSION The results of published papers show that the symptoms of several inflammatory diseases can be inhibited or treated by active ingredients from medicinal plants.

Abstract
Esculin, a coumarin compound derived from the traditional Chinese herbs such as Cortex Fraxini, has long been used for treating inflammatory and vascular diseases. In present study, we analyzed the role of esculin against macrophages and endotoxin shock induced by lipopolysaccharide (LPS) in mice. Here, we demonstrated that esculin suppressed inflammatory reactions in macrophages and protected mice from LPS-induced endotoxin shock. We found that esculin significantly inhibited the production of nitric oxide (NO) production via the inhibition of nuclear factor-κB (NF-κB) activation in macrophages. In animal model, esculin pretreatment significantly improved the survival rate of mice. LPS-induced increase of tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6) in serum, lung, liver and kidney were markedly inhibited by esculin. IL-10, an anti-inflammatory cytokine, was up-regulated by esculin. Moreover, the histopathological analyses showed that esculin significantly attenuated the tissues injury of lung, liver, kidney in endotoxic mice. In addition, esculin significantly diminished the protein expression of NF-κB p65 in lung, liver, kidney, which resulted in lower levels of inflammatory mediators. These results suggest that esculin may be a potential drug for treatment of various inflammatory diseases.

Abstract
BACKGROUND MASM, a novel derivative of matrine, has inhibitory effects on activation of macrophages, dendritic cells, and hepatic stellate cells and binds to ribosomal protein S5 (RPS5). This study was designed to evaluate the effect of MASM on murine-established lethal sepsis and its mechanisms. METHODS Mouse peritoneal macrophages and RAW264.7 cells that were infected with recombinant lentiviruses encoding shRPS5 were incubated with lipopolysaccharide (LPS) in the absence or presence of MASM in vitro. Endotoxemia induced by LPS injection and sepsis induced by cecal ligation and puncture was followed by MASM treatment. RESULTS MASM markedly attenuated LPS-induced release and messenger RNA expression of tumor necrosis factor α, interleukin 6, and NO/inducible NO synthase in murine peritoneal macrophages and RAW264.7 cells. Meanwhile, MASM inhibited LPS-induced activation of nuclear factor κB and MAPK pathways. Consistently, RPS5 suppressed LPS-induced inflammatory responses and at least in part mediated the antiinflammatory effect of MASM in vitro. Remarkably, delayed administration of MASM could significantly reduce mortality in mouse sepsis models, which was associated with the reduction in the inflammatory response, the attenuation in multiple organ injury, and the enhanced bacterial clearance. CONCLUSIONS MASM could be further explored for the treatments of sepsis, especially for administration later after the onset of sepsis.

Abstract
Matrine (MAT) is an active alkaloid extracted from Radix Sophora flavescens. The present study was to investigate whether MAT could effectively treat Adriamycin-induced nephropathy (AIN). AIN was induced in rats using a single injection of Adriamycin (ADR). Renal interleukin-6 (IL-6), IL-10, IL-17 and transforming growth factor-β (TGF-β) levels, and the expression of forkhead box protein 3 (Foxp3) and retinoid-related orphan nuclear receptor γt (Rorγt) was measured. AIN rats developed severe albuminuria, hypoalbuminaemia, hyperlipidaemia and podocyte injury. Daily administration of MAT (100mg/kg or 200mg/kg) significantly prevented ADR-induced podocyte injury, decreased AIN symptoms and improved renal pathology manifestations. Of note, treatment with MAT (100mg/kg) plus prednisone (Pre, 5mg/kg) had equivalent efficacy to that of Pre alone (10mg/kg). Additional findings showed that ADR triggered a disordered cytokine network and abnormal expression of Foxp3 and Rorγt in rats, as reflected by increased levels of IL-6, IL-10, TGF-β, Rorγt and decreased levels of IL-10 and Foxp3. Interestingly, MAT weakened the disordered cytokine network and normalized the expression of Foxp3 and Rorγt. In addition, a significant negative correlation was observed between the values of Foxp3/Rorγt and renal pathology scores. Finally, MAT normalized regulatory T cells (Treg)/ T-helper17 cells (Th17) ratio in peripheral blood mononuclear cells of AIN rats. These data indicate MAT prevents AIN through the modification of disordered plasma lipids and recovery of renal function, and this bioactivity is at least partly attributed to the suppression of renal inflammation and the regulation of the Treg/Th17 imbalance.

Abstract
The aim of the present study was to observe whether autophagy was induced by matrine, and to investigate the role of autophagy in the antitumor effects of matrine on human osteosarcoma MG-63 cells and its underlying mechanism. MG-63 cells were cultured in vitro in matrine at a concentration of 0.6, 0.8, 1.0 and 1.2 g/l for 0, 24, 48 and 72 h. A MTT assay was used to evaluate the proliferation inhibition of MG-63 cells by matrine, and Annexin V-fluorescein isothiocyanate/propidum iodide (PI) staining flow cytometry was used to analyze the apoptotic rate. Alterations in cell morphology was assessed by PI and Hoechst 33258 cell staining. Matrine-induced autophagy in MG-63 cells was confirmed by green fluorescent protein-microtubule-associated protein 1-light chain 3 (LC3) b transfection and fluorescence microscopy, and cell viability was investigated by MTT assay following inhibition of autophagy by chloroquine (CQ) pretreatment. The expression level of apoptosis-associated proteins B-cell lymphoma-2 (Bcl-2) and Bcl-2-like protein 4 (Bax), autophagy-associated LC3II protein, and the activation of extracellular signal-regulated kinase (ERK) was detected by western blotting. Cell proliferation was clearly inhibited by matrine in a dose- and time-dependent manner. Flow cytometry and Hoechst 33258/PI staining verified that matrine induced apoptosis in a time-dependent manner when cells were exposed to 1.1 g/l matrine; fluorescence microscopy demonstrated that green fluorescence puncta were enhanced with prolonged time of matrine incubation. Western blotting confirmed that the expression of pro-apoptosis-associated proteins Bax and LC3II, and phosphorylated-ERK were upregulated, and anti-apoptosis protein Bcl-2 was downregulated in a time-dependent manner following treatment with matrine. The cell viability of the matrine + CQ group was increased compared with the matrine group alone, which revealed that matrine treatment alone induced protective autophagy in MG-63 cells. In addiiton, expression of LC3II/LC3I decreased and the expression of BAX/Bcl-2 increased in the matrine + U0126 group compared with the matrine alone group. The present study demonstrated, to the best of our knowledge, for the first time that matrine induced protective autophagy via ERK activation in MG-63 cells, and matrine combined treatment with CQ or U0126 led to an increase in apoptosis in osteosarcoma cells.
