DICER1 and basal cell carcinoma: Furthermore, we tested additional cell lines; combined western blot analysis and measured relative band intensity showed >2-fold higher Dicer levels in melanoma cell lines (WM1552C and A2058) compared to basal cell carcinoma (BCC), primary melanocytes (n = 3) or other melanoma cell lines (WM35 and C32) (results not shown).
