We previously reported the constitutive expression of HOXB7 in both melanoma primary lesions and cell lines.8 Here we have confirmed and extended the expression pattern of HOXB7 performing qRT-PCR and western blot analyses on normal human epidermal melanocytes from foreskin and on a panel of melanoma cell lines derived from tumors at different stages of progression (Figs. 1a and 1b) (Supporting Information Table S1). The gene discussed is HOXB7; the disease is melanoma.
