Objective:To explore the mechanism of action of Dahuang Lingxian Formula in alleviating the inflammatory response of bile duct cells in LPS-induced intrahepatic bile duct inflammation model rats based on IL-6/JAK/STAT3 signaling pathway.Methods:Fifty SD rats were randomly divided into five groups,blank group,model group,choling tablets(0.5 g/kg),and low and high concentration groups(2.4 g/kg and 4.8 g/kg)of Dahuang Lingxian Formula,ten rats in each group.Except for the blank group,the rats in each group were injected with 1.25 mg/kg LPS at the common bile duct at one time to construct an animal model of intrahepatic bile duct infection.After gavage on day 8,liver tissues were taken from rats at the hepatic hilum,and the histopathological changes of the hepatic hilum and biliary tree were observed by HE staining.The expression levels of serum glutamic alanine transaminase(ALT),glutamic oxalacetic transaminase(AST),malondialdehyde(MDA)and superoxide dismutase(SOD)were measured by biochemical method.The expression levels of interleukin 6(IL-6),Janus protein tyrosine kinase 2(JAK2),signal transducer and activator of transcription 3(STAT3)in rat serum were measured by enzyme-linked immunosorbent assay(ELISA).Protein immunoblotting(WB)and real-time fluorescence quantitative PCR(RT-qPCR)were used to detect the expression levels of IL-6,JAK2,STAT3 protein and mRNA in biliary tree tissues.Results:①Compared with the blank group,the structures such as interlobular bile ducts in the hepatic sinusoids and portal duct area of the model rats were destroyed,and inflammatory cells infiltrated around them.The expression of ALT,AST,MDA,IL-6,JAK2 and STAT3 in the serum increased significantly,the expression level of SOD decreased,and the expression levels of IL-6,JAK2 and STAT3 proteins and mRNA increased.②Compared with the model group,the degree of liver pathological damage in rats in the Chiling Ning tablet group and the low and high concentration groups of Dahuang Lingxian Formula were improved,which could significantly reduce the expression levels of ALT,AST,MDA,IL-6,JAK2,STAT3 and up-regulate SOD in serum,and down-regulate the expression of IL-6,JAK2,STAT3 protein and mRNA,with the best effect in the high concentration group of Dahuang Lingxian Formula.③Compared with the choling tablet group,the rats in the low and high concentration groups of Dahuang Lingxian Formula tended to normalize the degree of liver pathological damage,without obvious inflammatory cell infiltration,and the expression levels of ALT,AST,MDA,IL-6,JAK2,STAT3 and the expression levels of IL-6,JAK2,STAT3 protein and mRNA in serum were reduced,and the expression levels of SOD were increased,with the best effect of Dahuang Lingxian Formula The treatment effect was best in the high concentration group.Conclusion:The mechanism may be related to the down-regulation of IL-6/JAK/STAT3 signaling pathway activation,and the best therapeutic effect was achieved by the high concentration group of Dahuang Lingxian Formula. 展开更多

Objective This study investigated the impact of occupational mercury(Hg) exposure on human gene transcription and expression, and its potential biological mechanisms.Methods Differentially expressed genes related to Hg exposure were identified and validated using gene expression microarray analysis and extended validation. Hg-exposed cell models and PTEN lowexpression models were established in vitro using 293T cells. PTEN gene expression was assessed using qRT-PCR, and Western blotting was used to measure PTEN, AKT, and PI3K protein levels. IL-6 expression was determined by ELISA.Results Combined findings from gene expression microarray analysis, bioinformatics, and population expansion validation indicated significant downregulation of the PTEN gene in the high-concentration Hg exposure group. In the Hg-exposed cell model(25 and 10 μmol/L), a significant decrease in PTEN expression was observed, accompanied by a significant increase in PI3K, AKT, and IL-6 expression.Similarly, a low-expression cell model demonstrated that PTEN gene knockdown led to a significant decrease in PTEN protein expression and a substantial increase in PI3K, AKT, and IL-6 levels.Conclusion This is the first study to report that Hg exposure downregulates the PTEN gene, activates the PI3K/AKT regulatory pathway, and increases the expression of inflammatory factors, ultimately resulting in kidney inflammation. 展开更多

Recently,abnormal expression of KIAA1199 has been detected in Epithelial Ovarian Cancer(EOC).However,the underlined anti-ovarian cancer mechanism of KIAA1199 remains to be enlightened.In our study,we performed to elucidate the effects of KIAA1199 on the advanced biological behavior of EOC cells through activation of the IL-6/STAT3 pathway.Confirmed by immunohistochemistry,KIAA1199 was highly expressed in ovarian borderline and malignant epithelial tumors.A retrospective analysis found that EOC patients with low expression of KIAA1199 had a significantly higher 5-year survival rate than those with high expression.Mechanistically,IL-6 was used to stimulate EOC cells,and the expression of KIAA1199,STAT3 and p-STAT3 increased after IL-6 stimulation.These results could show that KIAA1199 is transcriptionally activated by IL6/STAT3 pathway,thereby accelerating the deterioration of EOC.KIAA1199 could also be used as a poor prognosis factor and potential target in treatment. 展开更多

Tripartite motif containing 22 (TRIM22), a member of the TRIM/RBCC family, has been reported to activate the nuclear factor-kappa B (NF-kB) pathway in unstimulated macrophage cell lines, but the detailed mechanisms governing this activation remains unclear. We investigated this mechanism in HEK293T cells. We found that overexpression of TRIM22 could activate the NF-kB pathway and conversely, could inhibit the tumor necrosis factor receptor-associated factor 6 (TRAF6)-stimulated NF-kB pathway in HEK293T cells. Further experiments showed that TRIM22 could decrease the self-ubiquitination of TRAF6, and interact with and degrade transforming growth factor-13 activated kinase 1 binding protein 2 (TAB2), and that these effects could be partially rescued by a TRIM22 RING domain deletion mutant. Collectively, our data indicate that overexpression of TRIM22 may negatively regulate the TRAF6-stimulated NF-rd3 pathway by interacting with and degrading TAB2. 展开更多

Objective: To investigate whether remifentanil induced cardioprotecting effect is associated with expression of toll-like receptor 4 (TLR4), nuclear factor rB (NF-r.B) and serum interleukin -6 (IL-6). Methods: Fifty rabbits were randomly divided into 5 groups (n=10) according to the treatment: sham operation group (group A), ischemla-reperfusion group (group B), low-dose remifentanil group (group C), mediate-dose remifentanil group (group D), and high-dose remlfentanil group (group E) Myocardial TLR4 mRNA levels, NF-r.B protein expression and serum levels of IL-6 were observed in 120 min after reperfusion. Results: The myocardial expressions of TLR4 mRNA, NF-rd3 protein and IL-6 level in sera of groups B, C, D and E were elevated compared with group A. However, remifentanil significantly reduced the levels of TLR4 mRNA, NF- r.B protein expression and serum IL-6 in groups C, D and E compared with group B. There were remarkable differences between the groups (P〈O.O1). Conclusion: Intravenous remifentanil has protective effect against rabbit myocardial ischemia/reperfusion injury. This effect may be associated with TLR4, NF-r.B expressions on myocytes and serum level of IL-6 in a dose-dependent manner 展开更多

Frozen shoulder(FS)manifests as progressively worsening pain and a reduction in shoulder range of motion(ROM).Salvianolic acid B(SaB)is recently expected to be used in the treatment of fibrosis diseases including FS.We firstly demonstrate that SaB can effectively hinder the progression of oxidative stress,inflammation,and pathological fibrosis within the synovial tissue in FS,potentially leading to the reduction or reversal of capsule fibrosis and joint stiffness.For further clinical application,we design and synthesize a novel,superior,antioxidant and antibacterial CSMA-PBA/OD-DA(CPDA)hydrogel for the delivery of SaB.In vitro experiments demonstrate that the CPDA hydrogel exhibits excellent biocompatibility and rheological properties,rendering it suitable for intra-articular injections.Upon injection into the contracted joint cavity of FS model rat,the SaBCPDA hydrogel accelerate the recovery of ROM and exhibit superior anti-fibrosis effect,presenting the promise for the treatment of FS in vivo. 展开更多

Glioblastoma(GBM)is the most challenging malignant tumor of the central nervous system because of its high morbidity,mortality,and recurrence rate.Currently,mechanisms of GBM are still unclear and there is no effective drug for GBM in the clinic.Therefore,it is urgent to identify new drug targets and corresponding drugs for GBM.In this study,in silico analyses and experimental data show that sphingosine kinase 1(SPHK1)is up-regulated in GBM patients,and is strongly correlated with poor prognosis and reduced overall survival.Overexpression of SPHK1 promoted the proliferation,invasion,metastasis,and clonogenicity of GBM cells,while silencing SPHK1 had the opposite effect.SPHK1 promoted inflammation through the NF-κB/IL-6/STAT3 signaling pathway and led to the phosphorylation of JNK,activating the JNK-JUN and JNK-ATF3 pathways and promoting inflammation and proliferation of GBM cells by transcriptional activation of PTX3.SPHK1 interacted with PTX3 and formed a positive feedback loop to reciprocally increase expression,promote inflammation and GBM growth.Inhibition of SPHK1 by the inhibitor,PF543,also decreased tumorigenesis in the U87-MG and U251-MG SPHK1 orthotopic mouse models.In summary,we have characterized the role and molecular mechanisms by which SPHK1 promotes GBM,which may provide opportunities for SPHK1-targeted therapy. 展开更多

Objective:To study the key target genes and signaling pathways in the treatment of Allergic Rhinitis(AR)with Radix Aconiti Lateralis Preparata(aka Fuzi).Methods:The TCMPS and PubChem databases were used to screen the active ingredients and target genes of Fuzi using oral bioavailability and drug similarity as screening conditions,and the GeneCards database was used to screen the target genes of AR.The online tool Venny2.1 was used to screen the target genes of Fuzi for the treatment of Allergic Rhinitis;the STRING database was used to obtain the protein-protein interaction(PPI)network of drug-disease targets,and the key target genes were identified by the MCC algorithm.The potential biological processes and signaling pathways were identified by GO enrichment and KEGG enrichment analysis.Finally,animal experiments were conducted to demonstrate the therapeutic effect ofFuzi on Allergic Rhinitis.Results:The TCMSP,PubChem and GeneCards databases were used to screen the 21 active compound components of Fuzi and 68 potential therapeutic target genes of Fuzi for Allergic Rhinitis.PPI network analysis identified the top ten key target genes,namely:PTGS2,TNF,IL6,AKT1,ALB,STAT3,CCL2,CXCL8,VEGFA and JUN,GO functional and KEGG pathway enrichment analysis showed that the significantly enriched functions and pathways of Fuzi on Allergic Rhinitis were closely related to Allergic Rhinitis.Finally,animal experiments were conducted to verify that Fuzi is effective in the treatment of Allergic rhinitis.Conclusion:Increased expression of IL-6 and TNF-αin nasal mucosal tissues of patients with Allergic Rhinitis was positively correlated with indicators related to the disease activity of AllergicRhinitis.Fuzi ameliorated the inflammatory changes in mice with Allergic Rhinitis by inhibiting the activation of Toll-like signaling pathway in the nasal mucosa and decreasing the expression activity of IL-6 and TNF-α. 展开更多
