Expression of proteins representing cutaneous susceptibility signature to inflammation and tumors in hairless and haired mice. A: Immunofluorescence staining of IL1f6, S100a8, VDR, repetin, and MHCII. B: Western blot and densitometry analyses of expression of MHCII and COX-2 in UVB-induced lesions, which developed in hairless and haired mice. Data represent means ± SEM of at least three independent samples. ∗P < 0.05, ∗∗P < 0.01. Original magnification, ×40 (A). Ctrl (A) or C (B), control; T, tumor; US, UVB-irradiated skin.
