Bmi-1 was upregulated in BCC tissues. A. Bmi-1 levels were evaluated by qRT-PCR in four tissues, and normal human tissues were used as controls (*P<0.05). B. Bmi-1 and β-actin protein in the four BCC tissues and normal human tissues analyzed by Western blot analysis (*P<0.05). C. Bmi-1 expression and distribution was examined by Immunohistochemistry in BCC and normal tissues. Bmi-1 was highly expressed in BCC tissue, whereas low expression of Bmi-1 was observed in normal tissues. The experiment details were described under Materials and Methods section.
