OBJECTIVE The association between the -675 4G/5G polymorphism in PAI-1 gene and PCOS has been studied with inconclusive results. We sought to investigate this inconsistency by performing a comprehensive meta-analysis on the polymorphism. MATERIALS AND METHODS Searches were performed in the PubMed, Embase, CNKI and Wanfang databases, covering all papers. Statistical analysis was performed usin...

The serine protease inhibitor clade E member 1 (SERPINE1) gene has been suggested to exert great influence on the development of sepsis. But there is little overlap in the results of association between SERPINE1 -675 4G/5G polymorphism and sepsis.To get a more precise estimation of this association, we conducted a meta-analysis with a relatively larger sample size including 1806 cases and 2239 ...

BACKGROUND Idiopathic membranous nephropathy (MN) is one of the most common causes of nephrotic syndrome in adults, and 25% of MN patients proceed to end-stage renal disease. Plasminogen activator inhibitor type 1 (PAI-1) activity plays an important role in renal fibrosis. The objective of this study was to clarify the relationship between PAI-1 gene polymorphisms and the progression of MN-asso...

Plasminogen activator inhibitor type I (PAI-1) antigen concentrations follow a circadian oscillation peaking in the morning. Some individuals show no apparent circadian rhythm, while others show up to a 10-fold variation in PAI-1 over 24 hours. Results from experimental studies suggest that a polymorphism in the promoter of the gene for PAI-1 (4G5G) directly influences the circadian expression ...

Background: The Plasminogen Activator Inhibitor-1 gene 4G/5G (PAI-1 4G/5G) polymorphism has been suggestedto be associated with osteonecrosis of the femoral head (ONFH) susceptibility; however, the results are conflicting andinconclusive. We have carried out a comprehensive meta-analysis to derive a more precise estimation of the association.Methods: A comprehensive search in PubMed, EMBASE, Go...

OBJECTIVE The development of osteoporosis is associated with several risk factors, such as genetic structures that affect bone turnover and bone mass. The impact of genetic structures on osteoporosis is not known. Plasminogen activator inhibitor type-1 regulates the bone matrix and bone balance. This study assessed the correlation between plasminogen activator inhibitor type-1 gene 4G/5G polymo...

BACKGROUND A number of studies assessed the association of -675 4G/5G polymorphism in the promoter region of plasminogen activator inhibitor (PAI)-1 gene with asthma in different populations. However, most studies reported inconclusive results. A meta-analysis was conducted to investigate the association between polymorphism in the PAI-1 gene and asthma susceptibility. METHODS Databases inclu...

OBJECTIVE To investigate the prevalence of 4G5G polymorphism of plasminogen activator inhibitor-1 (PAI-1) gene in polycystic ovary syndrome (PCOS) and its functional significance. DESIGN Case-control study. METHODS We studied 98 patients and 64 controls. Body mass index (BMI) and waist-to-hip (WHR) ratio were determined. Blood samples were obtained for DNA analysis. PAI-1 plasma levels, ser...

Plasminogen activator inhibitor-1 (PAI1) can promote cancer progression, and its protein expression in tumors is an independent indicator of poor prognosis in many forms of cancer. Here, we show that high PAI1 mRNA levels also predict for shorter overall survival in two independent breast cancer data sets, highlighting the importance of its transcriptional regulation. The -675insG (4G/5G) singl...
