Comparison of gene expression ratios.

Pathway	Total # genes	Uw	Ux	Dw	Dx
Cell cycle	46	12	20	8	6
Chromatin structure	37	8	20	8	1
Translation	59	18	22	7	12
Spermatogenesis	32	10	12	9	1

Average gene expression ratios for genes involved in significantly regulated pathways are compared between Wt and Xpc^-/- mice. The table shows the number of genes that are up or down regulated to a higher extent after B[a]P exposure in either genotype.

Uw, up regulated to a higher extent in Wt mice. Ux, up regulated to a higher extent in Xpc^-/- mice. Dw, down regulated to a greater extent in Wt mice. Dx, down regulated to a greater extent in Xpc^-/- mice.
