title: Screening and evaluation of traditional Chinese medicine by microarray expression analysis.
abstract: BACKGROUND
  Salvia miltiorrhiza is a Chinese medicinal herb, which is widely used for the treatment of cardiovascular disorders. In this article, we investigated the effects of Salvia miltiorrhiza and its hydrophilic and lipophilic components (HCS and LCS) on human umbilical vein endothelial cells (HUVECs), and the molecular mechanism was explored by microarray gene expression profiling.
  
  
  METHODS
  Cell proliferation and migration were used to evaluate the angiogenic effects of HCS, LCS and total extract of Salvia miltiorrhiza (TES). Microarray technology was applied to detect the gene expression of HUVECs treated with TES, HCS and LCS. Besides, quantitative real-time PCR was used to verify the microarray results.
  
  
  RESULTS
  Our results showed that LCS inhibited the proliferation and migration of HUVECs, HCS promoted the proliferation and migration of HUVECs, and TES did not affect the viability of HUVECs at the concentration of 5 µg/mL. From the result of principle component analysis (PCA) of microarray data, the effect of LCS on HUVECs was significantly different from the other components. Moreover, there were more differentially expression genes in LCS group than in the other groups, which meant LCS had a strong influence on HUVECs. Compared with untreated cells, 511 significantly changed genes had been detected in LCS treated cells and 236 (approximately 46%) of them were up-regulated. The mRNA expression of IL-6 was found to be increased significantly in LCS group.
  
  
  CONCLUSIONS
  In Salvia miltiorrhiza, HCS and LCS had opposite effects on HUVECs. LCS showed significantly inhibitory action on HUVECs proliferation and migration. It was proposed that LCS could apply in the diseases caused by vascular anomaly hyperplasia. In the mechanism of action of LCS on HUVECs, the pathways of ErbB, MAPK, p53, oxidative phosphorylation and inflammatory response were involved.
