RESUMO
<p><b>OBJECTIVE</b>To investigate the effect of FXR on scavenger receptor class B type I (SR-BI) expression.</p><p><b>METHODS</b>Human vascular endothelium Eahy926 cells were treated with FXR agonist androsterone, and the specific target gene of FXR SHP mRNA was detected by RT-PCR. SR-BI mRNA and protein were determined using RT-PCR, real-time PCR and Western blotting.</p><p><b>RESULTS</b>The level of SHP mRNA in Eahy926 cells increased after androsterone treatment at different concentrations for 24 h, demonstrating FXR activation in the cells. RT-PCR, real-time PCR and Western blotting detected increased SR-BI expression at both mRNA and protein levels after FXR activation.</p><p><b>CONCLUSION</b>FXR increases the expression of SR-BI in human vascular endothelium cells.</p>
