It is important to find inducers that can safely and effectively differentiate stem cells into functional neurons for clinical use. In this study, we investigate the use of Radix Angelicae Sinensis as an inducer of neuronal differentiation. Primary human adipose-derived stem cells were obtained from adult subcutaneous fatty tissue, then pre-induced with 10% Radix Angelicae Sinensis injection for 24 hours, and incubated in serum-free Dulbecco＇s modified Eagle＇s medium/Nutrient Mixture F-12 containing 40% Radix Angelicae Sinensis to induce its differentiation into neuron-like cells. Butylated hydroxyanisole, a common in- ducer for neuronal differentiation, was used as the control. After human adipose-derived stem cells differentiated into neuron-like cells under the induction of Radix Angelicae Sinensis for 24 hours, the positive expression of neuron-specific enolase was lower than that of the butylated hydroxyani- sole-induced group, and the expression of glial fibrillary acidic protein was negative. Alter they were induced for 48 hours, the positive expression of neuron specific enolase in human adipose-derived stem cells was significantly higher than that of the butylated hydroxyanisole-induced group. Our experimental findings indicate that Radix Angelicae Sinensis can induce human adipose-derived stem cell differentiation into neuron-like cells and produce less cytotoxicity.展开更多

This study aims to elucidate the effective components and defattingmechanism based on network pharmacology. Methods: Traditional Chinese Medicine Systems PharmacologyDatabase and Analysis Platform was screened to collect the possible active ingredients and their CAS and SMILESwas searched in Pubchem, which further used for reverse molecular docking in Swiss Target Prediction database toobtain potential targets. Hyperlipidemia-related molecules were obtained from GeneCards database, and thepredicted targets of Angelicae sinensis radix for hyperlipidemia treatment were selected by Wayne diagram. Formechanism analysis, the protein-protein interactions were constructed with String, the Gene Oncology enrichmentanalysis and Kyoto Encyclopedia of Genes and Genomes analysis were conducted in DAVID. Results: Usingnetwork-based systems biology analysis, we predicted that 5 active ingredients in Angelicae sinensis radix hasantilipemic effects with 71 potential targets. Through Gene Oncology and Kyoto Encyclopedia of Genes andGenomes analysis, we found that the related signaling pathways mainly involved in arachidonic acid metabolism,and regulation of lipolysis in adipocytes. The related genes are ALOX5, CYP2C19, EPHX2, PTGS1, PTGS2,ADRB1, and ADRB3. Conclusion: Angelicae sinensis radix may alleviate hyperlipidemia through arachidonic acidmetabolism, and regulation of lipolysis in adipocytes. ALOX5, CYP2C19, EPHX2, PTGS1, PTGS2, ADRB1, andADRB3 may be new targets for treatment.展开更多

Methods The UPLC-PDA chromatogram of Xiaoyaosan was compared with that of Angelica Sinensis Radix. The relative retention time of each peak and the Uhraviolet spectra providing by PDA were used in the analyses. Constituents were isola- ted from Angelica Sinensis Radix under the guidance of UPLC-PDA investigation. Structures of the isolates were elu- cidated by NMR techniques. Anti-depression effect was evaluated on glutamate-induced neurons. Results Five marker peaks of Xiaoyaosan fingerprint were belong to Angelica Sinensis Radix, and they were determined as conife- ryl ferulate（ I）, E-butylidenephthalide （ II）, ligustilide （III）, Z-butylidenephthalide （ IV ）, 14-Acetoxy-12-sene- cioyloxytetradeca-2E,8E,10E-trien-4,6-diyn-l-ol（V）. Compound V was isolated from the plants of Umbelliferae for the first time. Treatment with compound I, III, IV can protect PC12 and SH-SY5Y cell from glutamate-induced cytotoxicity. Antidepression bioactivity of compound I was first investigated. Conclusion UPLC-PDA guided iso-lation technique was confirmed to be a rapid and accurate method to identify the main active constituents from An- gelica Sinensis Radix contrubuting to Xiaoyaosan.展开更多

Methods: This systems-based interactome analysis was designed to enforce the workflow of "ASR(herb)→compound→target protein→internal protein actions→ending regulated protein for hematopoiesis". This workflow was deployed with restrictions on regulated proteins expresses in bone marrow and anemia disease and futher validated with experiments. Results: The hematopoiesis mechanism of ASR might be accomplished through regulating pathways of cell proliferation towards hemopoiesis with cross-talking agents of spleen tyrosine kinase(SYK), Janus kinase 2(JAK2), and interleukin-2-inducible T-cell kinase(ITK). The hematopoietic function of ASR was also validated by colonyforming assay performed on mice bone marrow cells. As a result, SYK, JAK2 and ITK were activated. Conclusion: This study provides a new approach to systematically study and predict the therapeutic mechanism for ASR based on interactome analysis towards biological process with experimental validations.展开更多
