The plasminogen activation (PA) system is an extensively used mechanism for the generation of proteolytic activity in the extracellular matrix, where it contributes to tissue remodeling in a wide range of physiopathological processes. Despite the limited information available at present on plasminogen activators, their inhibitors and cognate receptors in skeletal muscle, increasing evidence is ...
Homozygous plasminogen activator inhibitor-i (PAI-1 )-deficient (PAI-1 /-I) mice were generated by homologous recombination in D3 embryonic stem cells. Deletion of the genomic sequences encompassing the transcription initiation site and the entire coding regions of murine PAI-i was demonstrated by Southern blot analysis. A 3.0-kb PAI-i-specific mRNA was identified by Northern blot analysis in l...
Glomerular plasminogen activator inhibitor-1 (PAI-1) steady-state mRNA and bioactivity were increased after the induction of an augmented form of antiglomerular basement membrane (GBM) antibody glomerulonephritis. PAI-1 mRNA expression was noted at 6 h, peaking at 1 day, and although falling thereafter, remained higher than that of the control group through Day 17. PAI-1 mRNA expression correla...
Background: To analyze the correlations between plasma coagulation factor VII (FVII), plasminogen activator inhibitor-1 (PAI-1), uric acid, and insulin resistance (IR) diabetic macroangiopathy (DMAP) in elderly patients with type 2 diabetes mellitus (T2DM).
The activity of plasminogen activators and inhibitors in the synovial fluid and plasma of patients with various forms of chronic arthritis was characterised. Tissue-type plasminogen activator antigen (t-PA:Ag), urokinase-type plasminogen activator antigen (u-PA:Ag), the proenzyme single chain u-PA (scu-PA), and plasminogen activator inhibitor (PAI) were measured in the synovial fluid and plasma...
The observation that aspirin inhibits the increment in tissue plasminogen activator ft-PA) activity induced by venous occlusion of the forearm became controversial with the publication of several nonconfirmatory studies. The current study was performed to confirm the original observation and determine the mechanism by which aspirin suppresses the incremental t-PA activity induced by venous occl...
The plasminogen activator cascade initiated by urokinase type plasminogen activator (u-PA) is involved in extracellular matrix degradation during the tumor invasion process. The plasminogen activator inhibitors 1 (PAI-1) and 2 (PAI-2) are two specific inhibitors of u-PA. We hypothesized that the balance between u-PA and its two inhibitors could be disrupted to favor plasminogen activation durin...
The t-PA/PAI-1 complex is a good indicator of the release of fibrinolysis activators and inhibitors from the vascular wall, but its clinical significance in chronic ischemic heart disease is unclear. The plasma levels of tissue-type plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1), and the t-PA/PAI-1 complex (including various coagulation factors) were assayed in 72 patie...
A lifelong bleeding disorder associated with a deficiency of plasminogen activator inhibitor type 1.
A 36-year-old patient was investigated for a lifelong history of epistaxis and delayed bleeding after minor surgeries. Deficiencies or abnormalities of the coagulation system, of platelet function, or of factor XIII and alpha-2-antiplasmin were excluded. Consistently, however, over a period of 7 years, a high basal euglobulin fibrinolytic activity was observed that was characterized by a high t...
BACKGROUND The present study was designed to assess the function of tissue plasminogen activator (t-PA) expression in allergic rhinitis. METHODS Age-matched t-PA gene knock out (t-PA(-/-)) and wild type (WT) mice were sensitised four times, and then challenged for six weeks with ovalbumin. The controls were treated with saline instead of ovalbumin. The structural change in the nasal mucosa wa...
