SDHA and melanoma: Western blot analysis combined with measured relative band intensity, normalized against succinate dehydrogenase (SDHA), showed >2 to 4-fold higher Dicer levels in melanoma cell lines (WM278, WM1552C and A375P) when compared to melanocyte-L or other melanoma cell lines (WM35 and A375M) (Fig. 5A-B).
