Special Issue Information

Dear Colleagues,

Matrix metalloproteinases (MMPs) are a very important group of enzymes involved in the reconstruction of connective tissue, especially in the processes of protein degradation, including collagen. The family of metalloproteinases is divided into six groups: collagenases, gelatinases, stromelysins, matrilysins, membrane-type metalloproteinases, and other unclassified metalloproteinases. The activity of these enzymes is regulated at several levels. These include the stage of gene transcription, proteolytic activation of the zymogen, inhibition of enzymatic activity, degradation of metalloproteinases, and mRNA stability. Tissue inhibitors of metalloproteinases, TIMPs are endogenous inhibitors of metalloproteinases. Both MMP and TIMP play an important role in the organism under normal conditions and in pathological states. It is particularly important that they play an important role in all stages of cancer development: from initiation through development, metastasis to angiogenesis and apoptosis. As a result of matrix degradation, peptide growth factors are released. Metalloproteinases can also affect cell mobility by degrading E-cadherins and by regulating signals sent by integrins. The role of MMPs in supporting the development of cancer, and in particular in the formation of metastasis, is to facilitate the epithelial to mesenchymal transition and passage through the blood vessels. In the process of angiogenesis, they release angiogenic factors and degrade the ECM. On the other hand, MMPs can inhibit the growth of tumors. Therefore, both MMP and TIMP are intensively researched as potential anticancer drugs. The aim of this Special Issue is to collect information regarding matrix metalloproteinases, their structure, their activity, molecular mechanisms of their action, their influence on carcinogenesis and metastasis and their role in normal metabolism. This collection of articles will include the most relevant work in the area of matrix metalloproteinases in normal and pathological conditions with the use of the latest methodologies applied. Therefore, this Special Issue is open to comprehensive review and original research papers and addresses the following topics:

  • Matrix metalloproteinases’ structure and activity
  • Matrix metalloproteinases in normal and pathological conditions
  • MMP role in cancer development
  • TIMP role in cancer development
  • MMP and TIMP as a target for new anticancer drug biosynthesis

Hypertension (HTN) is a leading risk factor for cardiovascular (CV) disease. Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) are thought to be actively involved in the remodeling of the CV extracellular matrix (ECM) during hypertensive damage. Therefore, in this study, we aimed to investigate serum levels of MMP-1 and TIMP-1 in patients with essential HTN and compare them with those of normotensive individuals. We measured serum concentrations of MMP-1 and TIMP-1 in 60 patients with HTN and 20 healthy controls using an ELISA. The obtained results showed that in patients with HTN, the mean levels of MMP-1 (1.82 ± 0.9 ng/mL) were significantly higher (p = 0.03) than the mean levels in the control group (1.19 ± 0.7 ng/mL). The levels of TIMP-1 in patients with essential HTN (0.44 ± 0.1 ng/mL) were also significantly higher (p = 0.005) than those in the control group (0.33 ± 0.1 ng/mL). In HTN, elevated serum MMP-1 levels may be associated with increased collagen degradation in the CV ECM, whereas elevated TIMP-1 levels may favor its accumulation and the development of pathological remodeling and fibrosis of the heart and arterial vessels.
