Extracellular matrix metalloproteinases - MMPs, also referred to as matrixines, provide a group of proteolytic enzymes. They belong to the family of endopeptidases that break down elements of extracellular matrix, resulting in its continuous remodelling. Their activity is regulated at multiple levels, while tissue inhibitors of metalloproteinases play a major role in this process. Metalloproteinases play a significant part in neoplastic processes due to their contribution to local tumour invasion and formation of distant metastases, as well as to angiogenesis Urinary tract tumours pose a significant diagnostic and therapeutic challenge and their incidence tends to grow every year. The aim of this part of review is to describe extracellular matrix and matrix metalloproteinases and to highlight the contribution of matrix metalloproteinases in the development of renal clear cell carcinoma.

Purpose: To evaluate the clinical significance of MMP-2 and TIMP-2 concentrations in the sera of patients diagnosed with colorectal cancer. Methods: The study group comprised 48 patients with colorectal carcinoma and 24 healthy controls. The serum concentration of MMP-2 and TIMP-2 proteins was evaluated by the ELISA method. Results: The mean level of MMP-2 in the sera of patients with colorectal cancer was 39.4 ng/ml and was significantly lower compared with the control (p<0.001). A decrease in TIMP-2 protein in the sera of patients with colorectal cancer was also observed where its mean level was 132.3 ng/ml. The concentration of MMP-2 and TIMP-2 did not correlated with any clinicopathological parameters, except for the patients’ age. In addition, the concentration of MMP-2 in the sera of patients with CRC correlated negatively with the number of white blood cells in the blood and the prothrombin index. The concentration of TIMP-2 correlated positively with potassium and urea concentration in the blood. Conclusions: The results of our study indicate lack of clinical usefulness of determining the levels of MMP-2 and TIMP-2 in the sera of patients with colorectal cancer. However, these proteins play an important role in the carcinogenesis of colorectal cancer.

Metaloproteinazy (MMPs) są enzymami proteolitycznymi mającymi zdolność degradacji macierzy zewnątrzkomórkowej. Uczestniczą w licznych procesach fizjologicznych, jednak najważniejsze ich funkcje związane są z patogenezą nowotworów. W badaniach potwierdzono, że na rozwój komórek nowotworowych znaczący wpływ ma zachwianie równowagi między MMPs i TIMPs (tkankowe inhibitory metaloproteinaz). MMPs i TIMPs wpływają na wzrost, migrację i inwazję komórek nowotworowych. Odpowiadają również za powstawanie odległych przerzutów. Informacje te potwierdzono, dokonując oceny analizy stężenia MMPs i TIMPs w osoczu chorych na glejaki mózgu, nowotwory płuc, piersi, raka szyjki macicy i nowotwory przewodu pokarmowego (żołądka, trzustki i jelita grubego). Poznanie mechanizmów działania metaloproteinaz macierzy zewnątrzkomórkowej i ich inhibitorów może mieć istotne znaczenie w opracowaniu nowych metod leczenia. Badania nad MMPs i TIMPs stwarzają szansę poznania skutecznej drogi walki z nowotworem. W pracy omówiono funkcję i podstawowe właściwości MMPs i TIMPs w rozwoju nowotworów raka jelita grubego, żołądka, trzustki, płuc oraz glejaka.

Matrix metalloproteinases (MMPs) are proteolytic enzymes. They have the ability to degrade the extracellular matrix. They also participate in many physiological processes however, but the most important functions of enzymes are related to the pathogenesis of cancer. Research have confirmed that imbalance between the MMPs and TIMPs has significant influence on tumor growth. Matrix metalloproteinases and their inhibitors have influence on growth, migration and invasion tumor cells. They are also responsible for the formation of distant metastases. This has been demonstrated on the basis of the analysis concentration of MMPs and TIMPs in the plasma of patients with gliomas, lung cancer, breast cancer, cervical cancer and gastrointestinal cancers. Understanding the mechanisms of action matrix metalloproteinases and their inhibitors may have a significant impact on new treatments. Research of MMPs and TIMPs are extremely important because they create opportunity to find effective way to battle with cancer. The present study aimed at discussing basic properties of MMPs and TIMPs in cancers progression: colorectal cancer, gastric cancer, pancreatic cancer, lung cancer and gliomas.
