	Hyperplasia, no. of cell layers*
Time after UV treatment	XPA mock	XPA + AdyXPA	WT
24 h	0.1 ± 0.2	[I] 0.2 ± 0.21	5.2 ± 1.1
		[BI] 8.3 ± 0.7
3 weeks	20.2 ± 3.4	[I] 12.1 ± 1.9	2.9 ± 0.5

2 months	22.3 ± 2.3	[I] 5.3 ± 1.1	2.1 ± 2.8
		[BI] 2.5 ± 1.5

^*Hyperplasia is given as the number of epidermal cell layers at the indicated times after in vivo exposure to UVB. Data are means ± SEM (n ≥ 3) or variation (n = 2).
