Description
One-month-old male Fischer 344 rats with an initial body weight of 150 g were used for this study and were divided into 7 groups: a control group (30 days), 2 groups intoxicated with L-NAME (50 mg/kg per day in the drinking water; Sigma Chemical Co) for 15 and 30 days, 2 groups treated with atorvastatin (100 mg/kg per day in the drinking water; Pfizer France) for 15 and 30 days and 2 groups receiving L-NAME (50 mg/kg/day) and atorvastatin (100 mg/kg/day) for 15 and 30 days (6 rats in each group). We compared transcriptional profile of aortic medias of control and treated rats using the Affymetrix U34 set. For each a set (chips A, B and C), we pooled RNAs from two rats. The same labelled extract was used for chips A, B and then C. We used 3 independant pools of RNA from 2 rats per treatment group to obtain biological triplicates.
