Gene expression ratios are presented of 18 differentially regulated genes involved in G2 to M phase transition based on microarray results. These 18 genes, of which 3 were down regulated and 15 were up regulated after B[a]P exposure, showed a trend towards a more pronounced induction in Xpc^-/- mice as compared to Wt mice (p = 0.086). However, a less extensive down regulation is not the same as a greater induction. Therefore, an additional p-value was calculated for the 15 up regulated genes, showing that 11 (indicated with *) out of these 15 up regulated genes are more induced in Xpc^-/- than in Wt mice (p = 0.024).
