Expression and activation of pro-MMP-2 and pro-MMP-9 during rat liver regeneration

Neutrophil Gelatinase-Associated Lipocalin (NGAL), Pro-Matrix Metalloproteinase-9 (pro-MMP-9) and Their Complex Pro-MMP-9/NGAL in Leukaemias

Matrix metalloproteinase (MMP)-9 and neutrophil gelatinase-associated lipocalin (NGAL) have gained attention as cancer biomarkers. The inactive zymogen form of MMP-9 (pro-MMP-9) also exists as a disulphide-linked heterodimer bound to NGAL in humans. Leukaemias represent a heterogeneous group of neoplasms, which vary in their clinical behavior and pathophysiology. In this review, we summarize th...

Involvement of PA/plasmin system in the processing of pro-MMP-9 and in the second step of pro-MMP-2 activation.

Pro-MMP2 activation is a two-step process resulting in (1) an intermediate 64 kDa form generated by the MT1-MMP activity, and (2) a mature 62 kDa form. Addition of plasminogen to HT1080 cells cultured under various conditions, or to their membrane preparation, induced a complete conversion of the intermediate MMP-2 form to the mature one, and processing of pro-MMP-9. The pro-MMP-2 activation wa...

Investigation of MMP-2 and MMP-9 activities in canine sera with dilated cardiomyopathy

Dilated cardiomyopathy (DCM) is accompanied by myocytes and connective tissue changes. Matrix metalloproteinases (MMPs) play important roles in cardiac remodeling. It seems that the gelatinases (MMP-2 and MMP-9) are effective enzymes in cardiomyopathy. Dilated cardiomyopathy was confirmed in 22 dogs (patient group) including 11 female and 11 male by clinical examination, auscultation, thoracic ...

Proteolytic cleavage of the pro-enzyme MMP-9 is required for the activation of MMP-9. What is the rationale for measuring the MMP-9 mRNA? Measuring the expression of MMP-9 proteins using immunohistochemical staining method

Expression characteristics of MMP-2 and MMP-9 in guinea pig ovaries during the estrous cycle.

We investigated the expression characteristics of matrix metalloproteinases (MMP)-2 and MMP-9 in the ovaries of normal adult guinea pigs during the estrous cycle. The estrous cycle was classified according to the appearance of the vaginal orifice and by vaginal exfoliated cell smears. Guinea pigs that had experienced at least two normal estrous cycles were selected. Ovaries were collected from ...
