Abstract
|
|
|
|
Nelumbinis Semen(NS) has been used in traditional medicine to treat diseases such as depression and diarrhea. In inflammatory responses, microglia produces molecules which are known to play roles in the central nervous system. And we previously studied NS inhibited nitric oxide synthase and secretion of tumor necrosis factor alpha. To explore the global gene expression profiles in BV-2 microglial cell line treated with NS, microarray analysis was performed. The cells were treated with LPS or NS plus LPS for 30min, 1h, 3h, and 6h, respectively. Of 45,101 known genes, with cutoff value of 3-fold change in the expression, 340, 644, 280 and 219 genes were upregulated and 503, 570, 694 and 484 were downregulated in NS treated cells at each time point. The results of the present study shows that treatment of NS reversed the LPS-induced upregulation of such genes as Ecoxsackievirus and adenovirus receptor(CAR), pellino 1, and S100P binding protein. It is thought that microarrays will play an ever-growing role in the advance of our understanding of the pharmacologic actions NS.
