Objective: To investigate the effect of reinioside C (RC) on the expression of lectin-like oxidized low density lipoprotein receptor (LOX)-1 mRNA and LOX-1 protein induced by oxidized low density lipoprotein (ox-LDL) in cultured human umbilical vein endothelial cells (HUVEC).
Methods: HUVECs were cultured with ox-LDL (50 mg/L) for 24 h in the absence or presence of RC (1, 3, and 10 micromol/L). The expressions of LOX-1 mRNA and LOX-1 protein were examined by RT-PCR and Western-blot.
Results: Incubation with ox-LDL (50 mg/L) significantly raised the expression of LOX-1 mRNA and LOX-1 protein,which was concentration-dependent.
Conclusion: RC can inhibit the increased expression of LOX-1 mRNA and LOX-1 protein induced by ox-LDL in HUVECs.
