ABSTRACT
This study was conducted to elucidate the effects of different fluid shear stress on the expression of IL-8 receptors CXCR1 and CXCR2 mRNA in endothelial cells, EA. Hy926 cells. The HUVEC cell lines were cultured in vitro and then exposed to 5.56, 10.02, and 15.27 dyn/cm2 fluid shear stress respectively for 5 min, 10 min, 15 min, 20 min, 25 min, 30 min, 1 h, 2 h, 4 h and 8 h. Semi-quantitative reversal transcription-polymerase chain reaction (RT-PCR) was used for detecting IL-8 receptors mRNA expression at different times. The results showed that, under 5. 56 dyn/cm2 shear stress, both the expression of CXCR1 and CXCR2 mRNA increased significantly with time (P<0.05). When exposed to 10. 02 dyn/cm2, the expression of CXCR1 mRNA was down-regulated with time on every occasion. CXCR2 mRNA increased temporally at 30 min, then it decreased gradually with time and finally went on at a constant lower level. When exposed to 15.27 dyn/cm2, both CXCR1 and CXCR2 mRNA expression decreased significantly with time (P<0.01). These data indicate that the expression of CXCR1 and CXCR2 mRNA of endothelial cell is regulated by fluid shear stress.
