Mechanisms of Sophora flavescens in the treatment of cervical squamous cell carcinoma based on comprehensive biological analysis,network pharmacology,and experimental verification

Objective:This study used comprehensive bioinformatics analysis and network pharmacology analysis to investigate the potentially relevant mechanisms of Sophora flavescens against cervical squamous cell carcinoma.Methods:Consistently altered genes involved in cervical squamous cell cancerization were analyzed in the GEO database.The chemical ingredients and target genes of Sophora flavescens were explored using the TCMSP database.We obtained the potential therapeutic targets of Sophora flavescens by intersecting the above genesets and validated them in the GEPIA database.The interaction between Sophora flavescens and target genes was predicted by molecular docking.RT-qPCR was used to verify the changes of target genes in HeLa cells treated with Sophora flavescens.Single-gene GSEA functional analysis were performed to determine the molecular mechanisms.Results:Fifteen genes related to the transformation of cervical squamous cell carcinoma were identified,among which AR and ESR1 were confirmed as targets for kaempferol,wighteone,formononetin,and phaseolinon.These compounds are the active ingredients in Sophora flavescens.Low expressions of AR and ESR1 correlate with a poor prognosis,while Sophora flavescens treatment increases the expression of AR and ESR1 in HeLa.GSEA analysis showed that AR and ESR1 mainly participate in the epithelial-mesenchymal transition in cervical squamous cell carcinoma.Conclusion:Sophora flavescens exert anti-tumor effects by targeting AR and ESR1,which may regulate cancer metastasis.

Research progress on flavonoids from the roots of Sophora flavescens Alt.and their biological activities

Sophora flavescens Alt.,a perennial herb of Sophora in Leguminosae family,was widely distributed in the north and south of China.Its root is utilized as a traditional Chinese medicine to clear heat,drain dampness,kill insect and promote urination by virtue of bitter and cold.Its chemical components are complex and diverse,mainly including alkaloids and flavonoids.Modern pharmacological studies have found that prenylflavonoids and quinolicidine alkaloids are the characteristic chemical constituents and the main active ingredients,with anti-inflammatory,anti-tumor,anti-oxidation,and other various biological activities.This study reviewed the chemical constituents of S.flavescens and the pharmacological effects of flavonoids in it in order to provide reference for further development.

Exploring the anti-diabetic effects and the underlying mechanisms of ethyl acetate extract from Sophora flavescens by integrating network pharmacology and pharmacological evaluation

Background:Sophora flavescens,a traditional Chinese herb medicine,has been used to prevent and cure type 2 diabetes mellitus(T2DM)both in folk medicine and medical institutions.Modern pharmacological studies have also demonstrated that the flavonoids obtained from Sophora flavescens ethyl acetate extract(SFE)exhibited potential anti-diabetic activity.Our previous study elucidated that SFE exerts anti-T2DM effects by regulating the host-microbial metabolic axis.In the present study,we further explored the pharmacodynamic effect and the potential targets of the anti-T2DM activity of SFE by integrating network pharmacology and pharmacological evaluations.Methods:The diabetic rat model was created by streptozotocin and oral administration with SFE for 8 weeks.Then,the T2DM-related index was estimated to assess the interventional effect of SFE.Network pharmacology was applied to identify the likely targets and the pathways modulated by SFE components.Furthermore,Western blotting was applied to verify the prediction.Results:Pharmacological evaluation in vivo revealed that SFE could markedly improve the blood glucose,serum insulin secretion,insulin resistance,liver glycogen synthesis,and the liver tissue structure in T2DM rats.Through network pharmacology analysis,101 active compounds of SFE and 114 targets belonging to 128 pathways were identified.The insulin,TNF,IL-6,and PI3K/Akt pathway may be the key targets and pathway.Based on the results of network pharmacology analysis,IRS/PI3K/Akt and IKK/NF-κB/TNF pathways were selected for further validation.Subsequently,experimental results of Western blotting confirmed that SFE may exert anti-T2DM effects by modulating the IRS/PI3K/Akt and IKK/NF-κB/TNF pathways.Conclusion:SFE may protect the T2DM rats by relieving the insulin resistance and inflammation through regulating the IRS/PI3K/Akt and IKK/NF-κB/TNF pathways.The results of the present study would improve the comprehension of the pharmacological basis of SFE against T2DM and provide a theoretical basis for the clinical use of Sophora flavescens.

Uncovering the mechanism of Sophora flavescens in the treatment of glioma based on network pharmacology

Glioma is a common primary intracranial tumor with high mortality and postoperative recurrence.Developing efficient therapies with lower toxicity is urgently needed.Sophora flavescens(SF)is a common Chinese medicine used to treat eczema,wet ulcers and itchy skin.Modern pharmacological studies have showed that SF has anti-glioma effects,but the mechanism of action remains unclear.This study aims to reveal the pharmacological mechanism of SF in treating glioma.The active components and related targets of SF were obtained from TCMSP.Genecard and Online Mendelian Inheritance in Man(OMIM)databases were used to explore the therapeutic targets for glioma.By making Venn diagram,we obtained 132 common targets of compounds and diseases.STRING databases and Cytoscape were used to construct diagrams of Protein-Protein Interaction(PPI)networks.Through the construction of PPI network,potential targets with degree value greater than the median were taken as core targets for further analysis.A total of 66 core targets were screened out.The degree values of TP53,HSP90AA1,MAPK1,and AKT1 were higher,indicating that these genes played important roles in this network.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analyses were used to further discover the mechanism of active components in SF.Through enrichment analysis,it was found that the core targets were mainly enriched in PI3K/AKT signaling pathway,cell senescence related signaling pathway and IL-17 signaling pathway.In order to further explore the binding between active components and selected target,molecular docking was carried out.Finally,SwissADME was used to determine whether the compound could cross the blood-brain barrier.Based on network pharmacology,we speculated that matrine and formononetin in SF might inhibit PI3K/AKT signaling pathway and cellular senescence related signaling pathway by targeting AKT1,TP53,MAPK1 and other key targets.In summary,this study preliminarily explored the target and mode of action of SF in the treatment of glioma,laying the foundation for further research on its mechanism.
