ABSTRACT
OBJECTIVE： To predict the anti-inflammatory active components and mechanism of couplet medicine of Notopterygium incisum-Angelica pubescens. METHODS： According to the principle of oral bioavailability≥30％ and drug- likeness≥0.18， active components of N. incisum and A. pubescens were screened； TCMSP was used to predict and screen the potential target of them. Using “Anti-inflammatory” as keyword， inflammatory related target genes were retrieved from human gene database Genecards. Common target was screened by mapping the target genes of active ingredients from couplet medicine of N. incisum-A. pubescens. The active ingredient-target network was established by using Cytoscape 3.5.1 software. The screened targets were used to construct the target protein interaction （PPI） network on the STRING V 10.5 platform. Its anti-inflammatory mechanism was studied by KEGG signaling pathway and GO biological enrichment analysis. RESULTS： Totally 15 active components such as coumarin， beta-sitosterol， ammidin， nodakenin were selected from couplet medicine of N. incisum-A. pubescens. Acting on 49 targets such as transcription factor AP-1， PI3-kinase subunit gamma， estrogen receptor， they mainly involved 19 signaling pathways such as hepatitis B and cell apoptosis， and were involved in 47 biological processes such as regulating inflammatory response and prostaglandin biosynthesis. CONCLUSIONS： The anti-inflammatory mechanism of active components of couplet medicine of N. incisum-A. pubescens on multi-target， multi-channel and multi-biological processes is predicted， and it points out the direction for further anti-inflammatory mechanism study.
ABSTRACT
Aim To investigate the apoptosis-inducing effects of AgLA2 on lung carcinoma cells SPC-A-1 and its mechanism in vitro.Methods The MTT assay was used to assess the proliferation of SPC-A-1 cells treated with AgLA2 in vitro.Apoptosis-inducing effects was investigated by DNA agarose gel electrophoresis,cell morphology and Elisa.RT-PCR was used to measure the expression of bcl-2 and bax mRNA,and immunocytochemistry was used to measure the expression of bcl-2 and bax protein.Results The IC50 of AgLA2 to SPC-A-1 cells was(3.447?0.436)mg?L-1.Treated with AgLA2,typical nuclear chromatine condensation and fragmentation were observed.The concentration of Caspase-3 in the group treated with AgLA2 was higher than that of the control group.Treated with AgLA2,bcl-2 mRNA,protein expression decreased while bax mRNA,protein expression increased.Conclusions AgLA2 can inhibit proliferation and induce apoptosis of SPC-A-1 cells.Its mechanism of action may be related to changing the ratio of bax/bcl-2 and the set-point of apoptosis,making the apoptosis power hold dominance.
