Complicated Pregnancy

Extracellular matrix (ECM) turnover is characterized by a unique balance between matrix metalloproteinases’ degradation activity and their natural inhibition by collagen specific tissue inhibitors. Human uterine ECM is a complex structure, majorly consisting of proteins as fibrillar collagen types I and III, fibronectin, and laminin. Collagenases are enzymes from the matrix metalloproteinases’ family, which are predominantly involved in fibrillar collagen types I and III degradation. They are mainly represented by matrix metalloproteinase-1, -13 (MMP-1, -13), naturally inhibited by tissue inhibitors (TIMP-1, -2). The collagen structure of the uterus has been shown to be impaired in women with preeclampsia. This is a result of MMPs/TIMPs dysregulation interplay. This review article summarizes the actual available research data in the literature about the role of MMP-1, MMP-13 and TIMP-1, and TIMP-2 in collagen types I and III turnover in healthy and complicated pregnancy. Their potential use as circulating markers for diagnosis, prognosis, and monitoring of the development of preeclampsia is discussed as well.

Diabetes mellitus types 1 and 2 are chronic diseases that cause serious health complications, including dermatologic problems. The diabetic skin is characterized by disturbances in collagen metabolism. A tissue remodeling depends on the degradation of extracellular matrix through the matrix metalloproteinases, which are regulated by e.g. the tissue inhibitors of metalloproteinases. The balance between matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs) is essential to maintain homeostasis in the skin. The aim of this study was to determine the concentration of metalloproteinase 2, tissue inhibitor of metalloproteinase 3 and the concentration of collagen type 1 in unwounded skin of diabetes type 1 and 2 and healthy controls. The treatment of diabetes resulted in a significant decrease of MMP2, increase of TIMP3 and COL1 concentrations in the skin as compared to the untreated diabetic skin. The concentrations of MMP2 in the skin of treated rats did not show significant differences from the healthy control group. TIMP3 concentrations in the skin of treated rats are not returned to the level observed in the control group. Disturbances of the extracellular matrix of the skin are similar in diabetes type 1 and 2. Application of insulin in diabetes therapy more preferably affects the extracellular matrix homeostasis of the skin.

The timely breakdown of extracellular matrix is essential for menstruation. Matrix metalloproteinases, which are able to degrade virtually all components of the extracellular matrix, are spatiotemporally expressed in the cyclic endometrium. The expression of most matrix metalloproteinases is regulated transcriptionally and their proteolytic activities are precisely controlled. The balance between matrix metalloproteinases and their specific tissue inhibitors is believed to be crucial for menstruation. This review focuses on the roles of matrix metalloproteinases and their tissue inhibitors in the initiation of menstruation and on the regulation of matrix metalloproteinase expression and activation. For example, the function of matrix metalloproteinases and their tissue inhibitors in endometrial re-epithelialization and angiogenesis during endometrial regeneration, when cell migration is facilitated to ensure endometrial repair, is discussed. This and other processes, although not fully resolved, serve to illustrate the involvement of matrix metalloproteinases and their tissue inhibitors in the process of menstruation.

ABSTRACT Matrix metalloproteinases (MMP) degrade components of the extracellular matrix and the balance between enzyme production and that of their specific tissue inhibitors (TIMPs) is likely to be crucial for menstruation. The temporal expression of messenger (m) RNA for proMMP-1 (interstitial collagenase),proMMP-3(stromelysin 1), TIMP-1 and TIMP-2 has been examined by Northern analysis in 73 individually-dated endometrial tissue samples from normal women. Thirteen tissues expressed the mRNA for proMMP-3 and mRNA for proMMP-1 was detected in eleven of the same tissues. All of these tissues were from the menstrual (11) or perimenstrual (2) phases. No expression of mRNA for proMMP-1 or -3 was detected between cycle days 4 and 26. By contrast, mRNA for both TIMP-1 and TIMP-2 was detected in all tissue samples. The abundance of mRNA for TIMP-1 was significantly elevated in menstrual tissue compared with tissue from the rest of the cycle. TIMP-2 mRNA expression displayed considerable variability between individual tissues but mean abundance was also higher in menstrual tissue. Menstruation is therefore associated with a perturbation of the balance between the expression of MMPs and their tissue inhibitors which could lead to tissue degradation.

Introduction: Tissue inhibitors of metalloproteinases (TIMP) and the matrix metalloproteinases (MMP) are involved in the spread of cancer. Methods: We have evaluated the matrix metalloproteinases’ (MMP-10, MMP-7) and their inhibitors’ (tissue inhibitors of metalloproteinases – TIMP-1, TIMP-2) mRNA expression in 61 esophageal cancer samples from patients who had undergone surgery, by using real-time quantitative RT-PCR, and correlated the results with the patient clinicopathologic features. Results: MMP-10, MMP-7, TIMP-1, TIMP-2 were overexpressed in 73%, 85%, 55% and 42% of esophageal cancer samples, respectively. The expression of MMP-10, TIMP-1, and TIMP-2 correlated with the tumor size. The MMP-7 overexpression was associated with the tumour stage (I, II vs III, p=0.05) and lymph node metastasis (N0 vs N1, p=0.037). Conclusions: We conclude that in the resected esophageal cancer an increased mRNA expression of MMP-7, MMP-10 and TIMP-1 correlated with clinicopathologic features. We suggest that these genes may play a role during progression of the disease.

The paper is focused on the evaluation of the serum levels of matrix metalloproteinases (MMP -2, MMP -3, MMP - 9), tissue inhibitors (TIMP -1 and TIMP -2), natriuretic peptides, pusle wave velocity in patients (pts) with heart failure with preserved ejection fraction (HFpEF) in 12 month after ST elevation myocardial infarction (STEMI). The study included 55 pts. The serum levels of MMP -2, MMP -3, MMP - 9, the precursor of matrix metalloproteinase -1 (proMMP -1), TIMP -1 and TIMP -2, high-sensitivity C-reactive protein (hsCRP) were determined by ELISA. BNP in whole blood was determined on panels Triage BNP test. The most pts had class II NYHA (49%), as was often II class angina (53%). Increases in levels of BNP were dependent on class of NYHA. The stiffness of the great arteries was associated with increasing in BNP and NT-proBNP. There were no changes in levels of proMMP-1, MMP 3, MMP-2, MMP-9. But the serum levels of TIMP-1, hsCRP were increased in pts with HFpEF after STEMI. A positive relationship between hsCRP and TIMP-1 was obtained. Moreover, we found decreasing in levels of MMP-3 in pts with increased rigidity without the risk of cardiovascular events.
