MMP-10, MMP-7, TIMP-1 and TIMP-2 mRNA expression in esophageal cancer

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 Matrix

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.

Development of the hypertension disorders in pregnant women is associated with the increase of the functional activity of innate immunity cells. RT-PCR assessment of the MMP-2 and TIMP-1 synthesis by peripheral blood phagocytes showed the significant elevation of the MMP-9 mRNA expression by neutrophils in women with chronic arterial hypertension (CAH) and TIMP-1 and TIMP-2 mRNA expression by monocytes in women with CAH and preeclampsia.
