Unraveling the mechanism of action of Shangxia Liangji formula for treating insomnia:a metabolomics and network pharmacology approach

Xia-Jie QuanHao LiangYong-Hong TangLi Jiang...

16-29页

查看更多>>摘要：Background:Insomnia is a prevalent clinical condition and Shangxia Liangji formula(SXLJF)is a well-established method of treatment.Nevertheless,the specific mechanism of action of SXLJF remains unclear.Methods:The mouse model of insomnia was established by intraperitoneal injection of para-chlorophenylalanine.Forty-two mice were randomly divided into a negative control group,model group,SXLJF group(18.72 g/kg/day),and positive control group(diazepam,2 mg/kg)and treated with the corresponding drugs for 7 consecutive days.The open field test and pentobarbital-induced sleeping test were conducted.LC-MS-based untargeted metabolomics and network pharmacology were applied to explore the potential targets of SXLJF for treating insomnia.Finally,key targets were validated using RT-qPCR.Results:Behavioral tests demonstrated that SXLJF reduced the total distance,average velocity,central distance,and sleep latency,and prolonged sleep duration.Metabolomics and network pharmacology revealed potential targets,signaling pathways,metabolic pathways,and metabolites associated with the anti-insomnia effects of SXLJF.Specifically,tyrosine hydroxylase(TH)and tyrosine metabolism emerged as crucial metabolic pathways and targets,respectively.RT-qPCR results supported the role of TH in the mechanism of SXLJF in treating insomnia.Conclusion:In conclusion,TH and tyrosine metabolism may represent significant targets and pathways for SXLJF in treating insomnia.

Deciphering the molecular mechanisms of Simiaowan in the treatment of hyperuricemia:in vivo and in silico approaches

Yong-Chang ZengJun-Hong WuDan-Dan XuKang He...

37-54页

查看更多>>摘要：Background:Simiaowan(SMW),a well-known traditional Chinese medicine,has been employed to treat hyperuricemia(HUA)and gout for centuries.However,the bioactive components and underlying mechanisms have not been elucidated.The objective of this study was to identify the active components and potential mechanisms of SMW by integrating pharmacological experimentation,serum pharmacochemistry,network pharmacology and molecular docking.Methods:HUA rats modelling by high-fat/high-sugar diet and potassium oxonate/adenine oral administration were used to evaluate the pharmacodynamic effects of SMW.UPLC-Q-Exactive-MS/MS was employed to detect the bioactive components present in SMW-containing serum.Network pharmacology and molecular docking were utilized to elucidate the potential targets and underlying mechanisms.Results:SMW effectively ameliorated HUA rats via the inhibition of uric acid(UA)production,promotion of UA excretion,improvement of lipid and glucose metabolic abnormalities,antioxidant,anti-inflammatory and anti-insulin resistance effects.A total of 73 compounds detected in SMW-containing serum were identified as potential active components,with alkaloids,flavonoids,organic acids,and terpenoids emerging as the primary active ingredients.Totally 203 corresponding targets were obtained as SMW anti-HUA/gout targets,which mainly participated in apoptosis,insulin resistance,TNF,PI3K-Akt,HIF-1,NF-κB,MAPK,IL-17 and TLR signaling pathways.Molecular docking indicated that active compounds(e.g.berberine,phellodendrine,quercetin,formononetin,ferulic acid)had superior binding abilities to the key targets(e.g.solute carrier family 22 member 12(URAT1),solute carrier family 22 member 6(OAT1),ATP-binding cassette sub-family G member 2(ABCG2),solute carrier family 2,facilitated glucose transporter member 9(GLUT9),xanthine dehydrogenase/oxidase(XDH),transcription factor p65(RELA),toll-like receptor 4(TLR4),prostaglandin G/H synthase 2(PTGS2),caspase-3(CASP3),insulin(INS)).Conclusion:SMW exerted regulatory influence over the disease network of HUA and gout through a multiplicity of components,targets,and pathways.Alkaloids,flavonoids,organic acids,and terpenoids were the primary active components,exerting anti-HUA/gout effects via antioxidant,anti-inflammatory,anti-insulin resistance,anti-apoptosis,inhibition of UA production,and promotion of UA excretion.This study revealed the active components and molecular mechanisms of SMW,providing insights into the development of natural products derived from SMW.

Single-cell transcriptomic profiling reveals ZEB1-mediated regulation in microglial subtypes and the impact of exercise on neuroinflammatory responses

Jin-Fang WuYi-Sheng ChenYu-Chun Xie

55-64页

查看更多>>摘要：Background:This study aims to identify distinct cellular subtypes within brain tissue using single-cell transcriptomic analysis,focusing on specific biomarkers that differentiate cell types and the effects of traditional and exercise therapy.Methods:Four samples were analyzed:older control(OC),older exercise(OE),younger control(YC),and younger exercise(YE).Single-cell RNA sequencing was used to distinguish cellular subtypes through their biomarker profiles.Data visualization included violin and t-SNE plots to illustrate biomarker expression across cell clusters such as oligodendrocytes,microglia,and astrocytes.Additionally,BV2 cells were exposed to amyloid-beta fragments to simulate Alzheimer's disease,assessing the impact of exercise-induced cellular responses.Results:Distinct cellular subtypes were identified:oligodendrocytes(MBP,St18),microglia(Dock8),and astrocytes(Aqp4,Gpc5).Sample OE was predominantly oligodendrocytes,while YE had more astrocytes,inhibitory neurons,and Canal-Retzius cells.YC showed a significant presence of Olfm3+ganglion neurons.ZEB1 gene knockout revealed changes in SMAD family gene expression,which regulate ferroptosis.Oxidative stress levels were also evaluated.Conclusion:This profiling enhances our understanding of brain cellular functions and interactions,potentially informing targeted therapies in neurological research.Exercise may influence brain cell immune responses and cell death pathways by regulating specific gene expressions,offering new insights for treating neuroinflammation and degeneration.

Mechanism of action of Linggui Zhugan Decoction in treating non-alcoholic fatty liver disease using untargeted metabolomics approach

Huan PeiRen-Lin LiXin-Ran SongQian-Qian Wan...

65-76页

查看更多>>摘要：Background:Non-alcoholic fatty liver disease(NAFLD)is a liver disorder characterized by the accumulation and degeneration of fat in the liver cells,a condition that may further deteriorate and lead to cirrhosis and liver cancer.Numerous studies showed that metabolic dysfunction can promote NAFLD development.Linggui Zhugan Decoction(LGZGD)has therapeutic effects on NAFLD.The mechanism of LGZGD still remains unclear.This study was to examine the impact of LGZGD on the metabolic processes involved in the development of NAFLD.Methods:A mice model of NAFLD was treated with LGZGD.The therapeutic potential of LGZGD was evaluated by assessing the activity of transaminases,lipids levels of blood,and pathological changes in the liver of the mice model of NAFLD.Additionally,this study also evaluated the influence of LGZGD on liver inflammation and oxidative stress.Results:The results of untargeted metabolomics analysis showed that LGZGD reduced the disordered lipid metabolism in NAFLD mice.LGZGD improved the oxidative stress and also reduced the levels of pro-inflammatory cytokines in the liver.Untargeted metabolomics analysis of liver samples revealed that LGZGD treatment improved metabolic disorders,including alanine,aspartate,glutamate,glycerophospholipid metabolism,and citrate cycle.Further RT-qPCR and Western blot results showed that LGZGD could regulate the expression of key enzymes in the metabolic pathway of the citrate cycle,including ATP-citrate lyase(ACLY),alanine-glyoxylate aminotransferase-2(AGXT2),phosphatidylethanolamine N-methyltransferase(PEMT),and succinate dehydrogenase(SDH).Conclusion:We found that LGZGD can treat NAFLD by reducing inflammatory responses,inhibiting oxidative stress,regulating alanine,aspartate,glutamate,and glycerophospholipid metabolism,and citrate cycle pathways.
