Effect of rosuvastatin and atorvastatin in combination with high-cholesterol diet on cholesterol homeostasis. Mus musculus

The aim of the study was to see any effect of rosuvastatina or atorvastatin on cholesterol homeostasis after 24 hours in C57BL/6 hyperlipidemic mice (induced by diet). Experiments were perfomed using a custom Steroltalk v2 microarray. Effect of both statins on drug metabolism was also evaluated. All experiments were done within the European sixth Framework program “Steroltalk” (www.steroltalk.net). Overall design: Animals were given one peroral application of vehicle (tap water), 20 mg/kg rosuvastatin or 40 mg/kg atorvastatin after one week of 1% cholesterol diet. After 24h they were sacrificed and total RNA was isolated from the livers. Each sample was hybridized with a reference sample to Steroltalk v2 microarrays.
