background: recurrent pregnancy loss (rpl) defined by two or more failed pregnancies before 20 weeks of gestation. several factors play a role in rpl including thrombophilic conditions which can be influenced by gene polymorphisms. plasminogen activator inhibitor-1 (pai-1) and angiotensin converting enzyme (ace) genes are closely related to fibrinolytic process, embryonic development and pregna...

Plasminogen activator inhibitor-1 (PAI-1) plasma levels have been consistently related to a polymorphism (4G/5G) of the PAI-1 gene. The renin-angiotensin pathway plays a role in the regulation of PAI-1 plasma levels. An insertion (I)/deletion (D) polymorphism of the angiotensin-converting enzyme (ACE) gene has been related to plasma and cellular ACE levels. In 1032 employees (446 men and 586 wo...

BACKGROUND Cytokine-mediated inflammation and coagulopathy may occur after cardiac surgery. In this study we investigated the temporal pattern of plasminogen activator inhibitor-1 (PAI-1) gene expression after cardiac surgery and its relation with PAI genotype, and obtained preliminary data regarding its relation to perioperative morbidity. METHODS The relative change in PAI-1 mRNA 1, 6, and ...

Background: Due to the lack of information about the role of 4G/5G polymorphism of PAI-1 Gene in susceptibility to thyroid tumors, this study was performed to evaluate the potential effects of this polymorphism on clinicopathologic features of thyroid tumors in Iranian Azeri Turkish patients. Methods:In this case-control study, 90 patients with thyroid tumors ...

Plasminogen activator inhibitor-1 (PAI-1) is an important regulator of numerous pathophysiological processes such as inflammation, thrombosis, angiogenesis and tumor metastasis. Its expression is induced by hypoxia at the transcriptional level, via the hypoxia inducible factor-1 (HIF-1) or -2 (HIF-2). In this study, we elucidated the mechanism of transcriptional regulation of mouse PAI-1 gene b...

Plasminogen activator inhibitor type 1 (PAI-1) is the primary physiologic inhibitor of the naturally occurring plasminogen activators. In higher primates two forms of mature PAI-1 mRNA (3.2 kb and 2.2 kb) arise by alternative cleavage and polyadenylation of PAI-1 hnRNA which is regulated in a tissue-specific fashion in humans. In other mammals only the 3.2 kb mRNA has been detected. The putativ...

Type 1 plasminogen activator inhibitor (PAI-1), a major physiological inhibitor of plasminogen activation, is an important component of the hepatic acute phase response. We studied the acute phase regulation of murine hepatic PAI-1 in response to systemic toxicity and local tissue injury in both wild-type mice and in mice in which the interleukin (IL)-1β gene had been inactivated by gene target...

Metabolic syndrome is associated with an increased risk of developing cardiovascular diseases and Plasminogen activator inhibitor 1 (PAI-1) overexpression may play a significant role in this process. A positive correlation between adipose tissue gene expression of PAI-1 and its serum concentration has been reported. Furthermore, high serum levels of thyroid hormones (T3 and T4) and PAI-1 have b...
