Levels of CD24 in the specimens of patients with melanoma. A. The levels of CD24 mRNA were measured by using RT-PCR. The levels of CD24 mRNA were higher in cancer tissues than matched normal tissues (P<0.05). GAPDH was used as an internal control. B. Representative results of paired of cancer tissue and corresponding normal tissue by western-blot. CD24 proteins were higher in cancer tissues than matched normal tissues (P<0.05). β-actin was used as an internal control. C. Immunohistochemical staining for CD24 protein in specimens. The nuclei were counterstained with hematoxylin. N: normal tissue; C: cancer tissue; Ng: negative control.
