Fruit.
2. experimental result
The changes in gene expression feature of 2.1Fn bacterium infection people's Gingival Fibroblasts HGF
For different time points (2,6,12,24,48 hours), it is based respectively on limma software package and analyzes to obtain differential expression
Gene takes the intersection of differential gene to obtain 971 genes and thermal map (see Fig. 3) is presented using cogena, can more see on a macro scale
Changes in gene expression feature after to bacteria-infected cells, horizontal axis is the sample changed according to natural time, longitudinal axis generation in the figure
Table gene expression profile is broadly divided into three coexpression clustering clusters (cluster), and wherein clustering cluster 1 and 2 is after bacteria-infected cells
Up-regulation gene cluster, 3 are down-regulated gene cluster.
2.2 coexpression path analysis are several immune and are metabolized relevant access
It is analyzed based on above-mentioned thermal map as a result, carrying out co-expression gene KEGG signal path analysis (Fig. 4), discovery is largely exempted from
Epidemic disease, bacterium infection and the relevant signal path of metabolism, such as cell factor and cytokine receptor interaction access (cytokine
Cytokine-receptor interaction pathway), Helicobacter pylori infection epithelial cell signal path
(epithelial cell signaling in helicobacter pylori infection pathway), Li Shiman are former
Insect infection signal path (leishmania infection pathway), glutathione metabolism access (glutathion
Metabolism pathway) etc..
2.3 coexpression drug reorientation analyses
By thermal map and access enrichment figure, finds the gene expression spectrum signature of Fn bacterium infection HGF cell, use cogena
Software carries out calculating drug reorientation analysis, (other candidate medicines of part as a result as shown in Figure 5 for co-expression gene clustering cluster 2
Object has blocked), demonstrate drug Rimexolone (Rimexolone, the 5th) and the antibacterial agent chlorine for treating Inflammatory eye conditions
Change the antibacterial action of benzyl ethoxy ammonium (methylbenzethonium chloride, the 7th), finds piperlongumine
(Piperlongumine) enrichment analysis result the 8th is ranked.It is enriched in conjunction with a large amount of inflammatory reactions in coexpression path analysis
As a result, piperlongumine has antibacterial and anti-inflammation functions, it is expected to develop into the drug with antibacterial and anti-inflammation functions.Therefore, piperlongumine
It can be applied to prepare in antibacterial-anti-inflammatory drug.
