Phenotype-dependent alteration of pathways and networks reveals a pure synergistic mechanism for compounds treating mouse cerebral ischemia
2015
Overview
Aim： Our previous studies have showed that ursodeoxycholic acid （UA） and jasminoidin （JA） effectively reduce cerebral infarct volume in mice. In this study we explored the pure synergistic mechanism of these compounds in treatment of mouse cerebral ischemia, which was defined as synergistic actions specific for phenotype variations after excluding interference from ineffective compounds. Methods： Mice with focal cerebral ischemia were treated with UA, JA or a combination JA and UA （JU）. Concha margaritifera （CM） was taken as ineffective compound. Cerebral infarct volume of the mice was determined, and the hippocampi were taken for microarray analysis. Particular signaling pathways and biological functions were enriched based on differentially expressed genes, and corresponding networks were constructed through Ingenuity Pathway Analysis. Results： In phenotype analysis, UA, JA, and JU significantly reduced the ischemic infarct volume with JU being superior to UA or JA alone, while CM was ineffective. As a result, 4 pathways enriched in CM were excluded. Core pathways in the phenotype-positive groups （UA or JA） were involved in neuronal homeostasis and neuropathology. JU-contributing pathways included all UA-contributing and the majority （71.7%） of JA-contributing pathways, and 10 new core pathways whose effects included inflammatory immunity, apoptosis and nervous system development. The functions of JU group included all functions of JA group, the majority （93.1%） of UA-contributing functions, and 3 new core functions, which focused on physiological system development and function. Conclusion： The pure synergism between UA and JA underlies 10 new core pathways and 3 new core functions, which are involved in inflammation, immune responses, apoptosis and nervous system development.
