A Microarray Analysis of Angiogenesis Modulation Effect of Xuefu Zhuyu Decoction （血府逐瘀汤） on Endothelial Cells

Objective： To study the angiogenesis modulation mechanism of Xuefu Zhuyu Decoction （血府逐瘀汤） on the endothelial cell line ECV304. Methods： ECV304 cells were treated with 2.5% Xuefu Zhuyu Decoction- containing serum （XFZYD-CS） for 24 h, 48 h or 72 h. Thiazolyl blue tetrazolium bromide （MTT）, fluorescence activating cell sorter （FACS）, migration, adhesion and in vitro tube formation assays were conducted to confirm an angiogenesis effect of XFZYD at 3 time points. An analysis of angiogenesis regulator profiles was performed at 3 times with real-time polymerase chain reaction （RT-PCR） superarray. Results： At 48 h, XFZYD-CS induced ECV304 significantly improved cell viability, number in S phase, migration, adhesion and tube formation. At 24 h and 72 h, only cell migration was elevated. Microarray results showed that the expression of 27 angiogenesis-related genes was changed. Conclusion： XFZYD-CS treatment induced angiogenesis on ECV304 cells with significant cellcular changes occurring at 48 h and genetic changes as early as 24 h.
