The basic etiologic factors causing this disease are unknown as yet. Matrix metalloproteinases (MMP) are involved in degradation of the extracellular matrix (ECM). Their proteolytic activity is regulated by tissue inhibitors of metalloproteinases (TIMPs). Tumor necrosis factor-α converting enzyme (TACE) is a membrane-bound disintegrin metalloproteinase that processes the membrane-associated cytokine proTNF-α to its mature soluble form, TNF-α induces the secretion of several MMPs. In order to study the expression of MMP-1, -2, -3 and -9, TIMP-1 and -2, TACE and TNF-α in endometrium and endometriotic tissue, we investigated formalin-fixed paraffin sections of endometriotic tissues and normal endometrium withimmunohistochemical techniques and in situ hybridisation. Furthermore, quantitative PCR was used for quantification of TACE-mRNA in fresh tissue. We found in this study significant higher protein expression of MMP-1 and TACE and significant lower protein expression of TIMP-1 and -2 in endometriotic tissue compared to endometrium. This data may suggest that high TACE expression causes the increased conversion of membrane-bound proTNF-α into its soluble form, which stimulates the increased secretion of MMP-1. The simultaneous deficiency of TIMP-1 and -2 in endometriotic tissuesuppose an additional proteinase inhibitor imbalance in endometriosis.\nAccess this chapter\nTax calculation will be finalised at checkout\nPurchases are for personal use only\nPreview\nUnable to display preview.
