Abstract:
Objective To explore the expression of lectin-like oxidized low-density lipoprotein receptor-1 ( LOX-1) in a rat model after balloon arterial injury and investigate the effect of cilostazol on the mRNA and protein expressions of LOX-1. Methods Twenty-four male SPF SD rats were randomly divided into 3 groups ( n =8 for each group) ,sham operation group,balloon arterial injury group and cilostazol treatment group. For the rats from balloon arterial injury group and cilostazol treatment group,the left common carotid artery were in- juried by a balloon catheter. The expression of LOX-1 mRNA and protein in neointimal hyperplasia after balloon arterial injury were examined by RT-PCR and immunohistochemistry respectively. The contents of MDA in blood serum was examined by TBA. Results LOX-1 mRNA and protein were expressed in the neointimal hyperplasia after balloon arterial injury but not in the sham-operation group. The expression level of LOX-1 was significantly lower in the cilostazol treatment group than that in the model group ( P
