Experimental Protocol


All animals were adapted to the RM3 (E) 801710 Soya-free powdered diet (B. S & S. [Scotland] Ltd, UK) over a period of 14 days. Quercetin was added separately to the semi-purified diets at a concentration of 6200 ppm (0.62 %; 6.2 g per kg). 65 male cytochrome P450 reductase null (KO) mice and 65 wild type (WT) C57BL/6 mice were reared, all aged between 6-8 weeks. Animals were housed 3 per cage, where both temperature and relative humidity were maintained within a range of 19-23oC and 40-70%, respectively. Twelve-hour periods of light were cycled with twelve-hour periods of darkness. For each strain of mouse, the following experimental design was used: a control group (25 mice) receiving powdered RM3 diet ad libitum and a group (25 mice) receiving a ‘high dose’ of quercetin (7 mg / mouse). The experimental diet was administered on day 15, following a 14-day adaptation period to the RM3 diet. Animals were sacrificed after 24 h. RNA samples destined for microarray analysis were only accepted and pooled into three groups if no aberrant signs of degradation (e.g. multiple peaks) were observed. The comprehensive gene expression profiles of the liver, jejunum, ileum, and colon were analyzed. In all cases, except those listed, RNA from 3 mice was pooled to form sample 1, another 3 mice to form sample 2, etc. Thus, 9 mice were used for the four experimental groups: wild-type, wild-type+quercetin, POR-null, POR-null+quercetin.
