Introduction: Urinary bladder cancer is a serious oncological problem that is the cause of many deaths worldwide. The processes of metastasis and origination of local tumor invasion depend on the extracellular matrix (ECM) degradation. The cancer microenvironment, particularly the ECM, may be considered a key factor in cancer progression. Matrix metalloproteinases (MMPs) are classified as the main factors responsible for the degradation of ECM components. Therefore, the aim of the study was to evaluate the expression and activity of matrix metalloproteinase 2 and 9 (MMP-2 and MMP-9) in urinary bladder cancer according to different stages. Material and methods: Urinary bladder tissue samples were analyzed. Cancer patients were divided into two groups: low-grade tumors (LG; Group I) and high-grade tumors (HG; Group II). Control tissue was obtained from the opposite site to the tumor. MMPs content and activity (actual and specific) were evaluated using ELISA and Western blot methods, respectively. Results: Both MMPs are present in high and low molecular complexes in healthy or bladder cancer tissues. The content of MMP-9 is enhanced in comparison with MMP-2, particularly in HG cancer tissue. The actual activity of MMP-2 was highest in LG cancer tissue whereas the actual activity of MMP-9 was highest in HG cancer. Specific activity of both MMPs was highest in LG cancer, but the activity of MMP-9 was higher in comparison with MMP-2. Conclusions: In conclusion, the content and specific activity of MMP-9 were increased in comparison with MMP-2. The revealed differences in content and activity of both MMPs demonstrate their different participation in ECM remodeling at different stages of cancer development. Moreover, it seems that MMP-9 has higher clinical utility than MMP-2 as a potential therapeutic option and a diagnostic biomarker of urinary bladder cancer.
