It is widely appreciated that inflammation and oxidant stress contribute to atherogenesis. Curcumin, a polyphenolic natural compound has been reported to possess anti-inflammatory and anti-oxidant actions. We hypothesized that curcumin could inhibit the development of atherosclerosis in the apoE/LDLR - double knockout mice fed with Western diet (21% fat, 0.15% cholesterol w/w, without cholic acid). Curcumin (purity 98%), premixed with diet, was given for 4 months at a dose of 0.3 mg/per day/per mouse. In this model curcumin inhibited atherogenesis, measured both by "en face" method (25,15±2,9% vs. 19,2±0,6%, p<0,05) and "cross-section" method (565867±39764 µm2 vs. 299201±20373 µm2, p<0,05). Importantly, curcumin influenced neither the concentrations of cholesterol and triglycerides in blood nor animal body weight. To our knowledge, this is the first report that shows the anti-atherogenic effect of low dose of curcumin in fine model of atherosclerosis: gene-targeted apoE/LDLR - double knockout mice.

Nuclear factor - B (NF-B) is a good therapeutic target for cardiovascular disease and numerous efforts are being made to develop safe NF-B inhibitors. Nowadays many authors address NF-B as a major therapeutic target in atherosclerosis, especially for preventive measures, in the light of two main hypothesis of atherosclerosis: oxidation and inflammation. We hypothesized that ammonium pyrrolidinedithioocarbamate (PDTC) - a well-known inhibitor of NF-B could inhibit the development of atherosclerosis in this experimental model. We used apoE/LDLR - DKO mouse model, which is considered as a one of the best models to study the anti-atherosclerotic effect of drugs. In this model PDTC inhibited atherogenesis, measured both by "en face" method (25,15±2,9% vs. 15,63±0,6%) and "cross-section" method (565867±39764 µm2 vs. 291695±30384 µm2). Moreover, PDTC did not change the profile of cholesterol and triglycerides in blood. To our knowledge, this is the first report that shows the effect of PDTC on atherogenesis in gene-targeted apoE/LDLR - double knockout mice.
