چکیده مقاله:

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, Google Scholar, and ISI Web of Knowledge databaseswas conducted to identify all eligible case-control publications investigating the association between PAI-1 4G/5Gpolymorphism and ONFH risk. Odds ratios (OR) and corresponding 95% confidence intervals (CI) were used toassess the association.Results: A total of six studies with 456 cases and 1,019 controls were included in this review. Three studies werefrom Caucasian descendants and the three others were from East Asian descendants. Overall analysis suggestsa significant association between PAI-1 4G/5G polymorphism and ONFH risk under the allele model (4G vs. 5G:OR =1.540, 95% CI =1.055-2.248, P=0.025) and the recessive model (4G4G vs. 4G5G+5G5G: OR=1.931, 95% CI:1.162-3.207, P=0.011). When stratified by ethnicity, we have found a significant association between PAI-1 4G/5Gpolymorphism and ONFH risk among the Caucasian (4G5G vs. 5G5G: OR=1.806, 95% CI: 1.064-3.067, P=0.029) andEast Asians (4G4G vs. 5G5G: OR=1.619, 95% CI: 1.025-2.556, P=0.039 and 4G4G vs. 4G5G+5G5G: OR=1.665, 95%CI: 1.207-2.297, P=0.002).Conclusion: The present meta-analysis suggested that PAI-1 4G/5G (rs1799889) polymorphism is a potential riskfactor for development of ONFH. However, large-scale and well-designed case-control studies in different ethnicitiesare required to validate these results. Level of evidence: II

Association between plasminogen activator inhibitor gene polymorphisms and osteonecrosis of the femoral head susceptibility

This study aimed to analyze the correlation of the plasminogen activator inhibitor (PAI-1) gene polymorphisms (rs6092 and rs7242) with susceptibility of osteonecrosis of the femoral head (ONFH).This case-control study included 106 ONFH patients and 151 healthy controls. PAI-1 polymorphisms were genotyped by polymerase chain reaction (PCR) with direct sequencing. The genotype distribution of pol...

Genetic polymorphisms in plasminogen activator inhibitor-1 predict susceptibility to steroid-induced osteonecrosis of the femoral head in Chinese population

BACKGROUND Steroid usage has been considered as a leading cause of non-traumatic osteonecrosis of the femoral head (ONFH), which is involved in hypo-fibrinolysis and blood supply interruption. Genetic polymorphisms in plasminogen activator inhibitor-1 (PAI-1) have been demonstrated to be associated with ONFH risk in several populations. However, this relationship has not been established in Chi...

PAI-1 4G/5G Polymorphism Contributes to Cancer Susceptibility: Evidence from Meta-Analysis

BACKGROUND The plasminogen activator inhibitor-1 (PAI-1) is expressed in many cancer cell types and allows the modulation of cancer growth, invasion and angiogenesis. To date, studies investigated the association between a functional polymorphism in PAI-1 (4G/5G) and risk of cancer have shown inclusive results. METHODS A meta-analysis based on 25 case-control studies was performed to address ...

PAI-1 promoter 4G/5G polymorphism (rs1799768) contributes to tumor susceptibility: Evidence from meta-analysis

Plasminogen activator inhibitor-1 (PAI-1), belonging to the urokinase plasminogen activation (uPA) system, is involved in cancer development and progression. The PAI-1 promoter 4G/5G polymorphism was shown to contribute to genetic susceptibility to cancer, although the results were inconsistent. To assess this relationship more precisely, a meta-analysis was performed. The electronic databases ...
