A microarray analysis of angiogenesis modulation effect of Xuefu Zhuyu Decoction on endothelial cells.

ABSTRACT

OBJECTIVE: To study the angiogenesis modulation mechanism of Xuefu Zhuyu Decoction () 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.
