Expression of matrix metalloproteinases (MMP-2 and MMP-9) in tissues of benign (nevi, dysplastic nevus) and malignant skin pigmentation neoplasms in 60 patients by immunohistochemical method was studied.
MMP-9 expression in melanoma cells was 6 and 2.9 times higher than in nevi and dysplastic nevi. MMP-2 expression was maximal in dysplastic nevi and exceeded expression values in nevi by 1.4 times (p<0.05); there was no significant difference in the expression of MMP-2 between dysplastic nevi and melanoma. Thus, significant differences in the expression level of MMP-9 with the dynamics of the index increase in the «nevus – dysplastic nevus – melanoma» series are shown. A more pronounced intensity of staining of both MMPs (with a predominance of strongly and moderately positive reactions) was characteristic of tissues of the malignant neoplasms of the skin.
