1

Immunohistochemistry of formaldehyde-fixed paraffin-embedded SCC (n = 12) and BCC (n = 9) samples was carried out as described in Methods.

2

Expression level was scored as “moderate” when staining intensity was comparable, as “strong” when staining was stronger, and as “low” when staining was weaker than that of epidermis present in the same section, respectively.
