Expression of EMT regulatory proteins in BCCs induced in hairless and haired mice. A: Immunofluorescence staining showing expression of E-cadherin, fibronectin, twist, snail, and vimentin in UVB-induced BCCs in hairless and haired mice. B: Western blot and densitometry analyses showing expression of snail, slug, twist, and E-cadherin in control skin, UVB-irradiated skin, and UVB-induced BCCs in hairless and haired mice (n = 3). ∗P < 0.05, ∗∗P < 0.01. C, control; T, tumor; US, UVB-irradiated skin.
