초록
Objectives : The source is from the flower of Carthamus tinctorius L., family Compositae. It is used in clinical medicine to promote blood circulation, remove blood stasis, promote menstruation and alleviate pain. In the present study, we investigated the genome wide analysis of Carthami Flos on the intra-cranial hemorrhage(ICH) model. Methods : ICH in rat was induced by injection of collagenase type IV and Carthami Flos extract(CFe) was administered orally. The molecular profile of cerebral hemorrhage in rat brain tissue was measured using microarray technique to identify up- or down- regulated genes in brain tissue. Results : Expression profile showed that diverse genes were up- or down-regulated by ICH induction. Administration of CFe restored the expression level of some of altered genes by ICH to normal expressional level. Interestingly, these recovered genes by CFe were involved in the same biological pathways which were significantly activated or suppressed by ICH. Conclusion : The above results might explain the therapeutic mechanism of CFe on ICH. Further, by analyzing interaction network, core genes was identified which could be key molecular targets of CFe against ICH.
