Matrix Metalloproteinase-19 Expression in Normal and Diseased Skin: Dysregulation by Epidermal Proliferation

Popis výsledku v původním jazyce

Most of the matrix metalloproteinases (MMP) are not expressed in normal intact skin but they are upregulated in inflamed or diseased skin. The recently cloned MMP-19 is one of the few MMP members that are also expressed in healthy epidermis. In this study, we found that MMP-19 is generally coexpressed with cytokeratin 14 that is confined to keratinocytes of the stratum basale. MMP-19 was also detected in hair follicles, sebaceous glands, and eccrine sweat glands. Its expression, however, changed in cutaneous diseases exhibiting increased alternations of epidermal proliferation, such as psoriasis, eczema, and tinea. In the affected area, MMP-19 was also found in suprabasal and spinous epidermal layers. We also studied the regulation of MMP-19 expressionat the protein level, as well as by using a promoter assay. The constitutive expression of MMP-19 was upregulated with phorbol myristate acetate and downregulated with retinoic acid and dexamethasone. Tumor necrosis factor-alpha, interle
