摘要: Friend leukemia integration site 1 (Fli-1) has been reported as the first nuclear marker of endothelial differentiation; it is expressed in leukocytes and recently demonstrated melanomas. Formalin-fixed, paraffin-embedded tissue sections from 97 melanomas including 69 cases primary 28 metastatic were evaluated by immunohistochemistry. Five melanoma cell lines Western blot immunocytochemistry. Fli-1 expression was observed all lines. higher than tumors (r=0.208, p=0.041, Spearman correlation), positively correlated with Ki-67 (r=0.233, p=0.022, presence an ulcer tumor (r=0.267, p=0.030, correlation). Therefore, malignant appears to be associated biologically more aggressive tumors.
