Abstract
Tissue-type plasminogen activator (tPA) encoded by PLAT is a major mediator that promotes fibrinolysis and prevents thrombosis. Pathogenetic mutations in PLAT associated with venous thromboembolism have rarely been reported. Here, we report the first case of a homozygous point mutation c.1411T>C (p.Y471H) in PLAT leading to thromboembolic events and conduct related functional studies. The corresponding tPA mutant protein (tPA-Y471H) and wild-type tPA (tPA-WT) were synthesized in vitro, and mutant mice (PLATH/H mice) were constructed. The molecular docking and surface plasmon resonance results indicated that the mutation impeded the hydrogen-bonding interactions between the protease domain of tPA and the kringle 4 domain of plasminogen, and the binding affinity of tPA and plasminogen was significantly reduced with a difference of one order of magnitude. mRNA half-life assay showed that the half-life of tPA-Y471H was shortened. The inferior vena cava thrombosis model showed that the rate of venous thrombosis in PLATH/H mice was 80% compared with 53% in wild-type mice. Our data suggested a novel role for the protease domain of tPA in efficient plasminogen activation, and demonstrated that this tPA mutation could reduce the fibrinolysis function of the body and lead to an increased propensity for thrombosis.

Cho HY, Park HS, Ahn EH, Ko EJ, Park HW, Kim YR, Kim JH, Lee WS, Kim NK. Association of Polymorphisms in Plasminogen Activator Inhibitor-1 ( PAI-1), Tissue Plasminogen Activator ( tPA), and Renin ( REN) with Recurrent Pregnancy Loss in Korean Women. J Pers Med 2021; 11:jpm11121378. [PMID: 34945850 PMCID: PMC8705673 DOI: 10.3390/jpm11121378] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 12/09/2021] [Accepted: 12/14/2021] [Indexed: 02/07/2023] Open
Abstract
Recurrent pregnancy loss (RPL) is defined as two or more consecutive pregnancy losses prior to 20 weeks of gestational age. Various factors, including immune dysfunction, endocrine disorders, coagulation abnormality, and genetic disorders influence RPL. In particular, plasminogen activator inhibitor-1 (PAI-1), tissue plasminogen activator (tPA), and renin (REN) have important roles in the thrombotic and thrombolytic systems, and abnormal expression of these genes have a reported negative correlation with pregnancy maintenance. Moreover, some polymorphisms of the three genes are related to expression levels and thrombotic disorder. Therefore, we investigated whether polymorphisms of PAI-1, tPA, and REN are linked to RPL. Genotyping of the six polymorphisms (PAI-1 rs11178, rs1050955, tPA rs4646972, rs2020918, REN rs1464816, and rs5707) was performed using polymerase chain reaction (PCR)-restriction fragment length polymorphism and associations of the polymorphisms with RPL were evaluated by statistical analysis. The polymorphism PAI-1 rs1050955 GA+AA was associated with decreased RPL risk (AOR, 0.528; 95% CI 0.356–0.781; p = 0.001) as was the REN 10795 rs5707 GG genotype (AOR, 0.487; 95% CI 0.301–0.787; p = 0.003). In contrast, the tPA rs4646972 II genotype correlated with increased RPL risk (AOR, 1.606; 95% CI, 1.047–2.463; p = 0.030). This study provides evidence that tPA Alu rs4646972 may contribute to the risk of idiopathic RPL, but PAI-1 12068 rs1050955 and REN 10795 rs5707 are associated with a decreased risk of RPL. Therefore, these alleles may be useful as biomarkers to evaluate the risk of RPL.

Abstract
Background Epilepsy is one of the most common chronic disabling neurologic diseases. The purpose of our study was to investigate whether there is an association between t-PA (tissue plasminogen activator, rs2020918 and rs4646972), PAI-1 (plasminogen activator inhibitor 1, rs1799768) polymorphisms and susceptibility to temporal lobe epilepsy (TLE) in Chinese Han population. Method One hundred and twenty-one cases of patients who were diagnosed as TLE and 146 normal controls were enrolled and the genotypes of t-PA and PAI-1 were detected by polymerase chain reaction-ligase detection reaction (PCR-LDR) method after the genomic DNA being extracted from peripheral blood. Result There were significant differences for the genotypic frequencies at the two polymorphic sites in t-PA gene between TLE patients and controls (P = 0.019; P = 0.001). Furthermore, the frequency of rs2020918 (C > T) with T (CT + TT) and rs4646972 (311 bp insertion/−) with 311 bp deletion (311 bp/− + −/−) was significantly higher among TLE patients relative to controls respectively (P = 0.006; P = 0.001). However, no significant difference in genotypic and allelic frequency was found at the polymorphic site in PAI-1 gene between TLE patients and controls (P = 0.735). Conclusion We reported for the first time to our knowledge the significant role of the two SNPs in t-PA gene (rs2020918 and rs4646972) in developing susceptibility to TLE in Chinese Han population.

Association of Platelet Membrane Glycoprotein HPA-2a/b, GP VI T13254C, and GP Ib α VNTR Polymorphisms with Risk of Coronary Artery Disease: A Meta-Analysis. BIOMED RESEARCH INTERNATIONAL 2017; 2017:1538750. [PMID: 28607925 PMCID: PMC5451768 DOI: 10.1155/2017/1538750] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/24/2016] [Revised: 04/14/2017] [Accepted: 04/23/2017] [Indexed: 02/08/2023]
Abstract
BACKGROUND AND AIMS Recently, controversial results have been reported regarding the association of the polymorphisms of platelet membrane glycoproteins (HPA-2a/b, GP VI T13254C, and GP Ibα VNTR) with coronary artery disease (CAD). We performed this meta-analysis to further assess the polymorphisms of platelet membrane glycoproteins with a risk of CAD. METHODS A systematic electronic literature search was conducted in Embase, Cochrane Library, PubMed, and the Chinese Biomedical Literature Database (CBM). Analyses were performed using the Cochrane software package Review Manager 5.2 and Stata 12.0 software package. RESULTS Twenty-nine full-text articles were included in the meta-analysis. Based on random-effects meta-analysis, a significant association between the HPA-2a/b polymorphism and CAD was identified (allele model: odds ratio = 1.43, 95% confidence interval = 1.07-1.91; dominant genetic model: odds ratio = 1.57, 95% confidence interval = 1.08-2.28). Our study showed no association between the GP VI T13254C polymorphism and CAD in either a random-effects model or a fixed-effects model. Furthermore, there was no evidence to suggest that the GP Ibα VNTR polymorphism was associated with CAD in any of the genetic analysis models. CONCLUSIONS The HPA-2a/b polymorphism correlated significantly with a risk of CAD, and the HPA-2b allele and the HPA-2ab + HPA-2bb genotype may increase the risk of CAD. There was no evidence to suggest that polymorphisms of GP VI T13254C and GP Ibα VNTR were associated with CAD.

Abstract
BACKGROUND With an increase in the discovery of newer genetic loci/polymorphisms in complex multifactorial diseases, there is also an increased need for methods that can simultaneously genotype multiple loci in a cost-effective manner. Using coronary artery disease (CAD) as a model, the study aimed to develop an in-house multilocus assay for simultaneous detection of 17 genetic variants in 11 genes implicated in CAD. METHODS A multiplex polymerase chain reaction (PCR)-based reverse line blot hybridization (MPCR-RLBH) approach was used, where each DNA sample was amplified using two separate MPCRs, and the alleles were genotyped using covalently immobilized, amino-linked sequence-specific oligonucleotide probes using an enhanced chemiluminescence system. The assay performance was tested on 75 healthy controls and 75 angiographically proven CAD cases. Validation was done by automated Sanger sequencing. RESULTS The assay could successfully discriminate both the alleles at CETP (I405V), LPL (D9N), NOS3 (T-786G and E298D), LIPC (C-514T), FGB (G-455A), ITGB3 (L33P), AGT (M235T), and MTR (A2756G) loci. Certain mutations included in this assay such as ins242G, ins397G, E387K, L393K in the LDLR; N291S in the LPL; D442G in the CETP; and T833C in the CBS genes were found to be absent. The genotype results obtained using this assay showed 100% concordance with sequencing. CONCLUSION The study demonstrated development and validation of a multiplex SNP genotyping assay that can be used to assess genetic risk factors in CAD. The assay provides a cost-effective alternative to expensive high throughput genotyping systems in common molecular research laboratories.

Abstract
BACKGROUND The PlA2 polymorphism of glycoprotein IIIa (GPIIIa) has been previously identified as being associated with myocardial infarction (MI), but whether this represents a true association is entirely unclear due to differences in findings from different studies. We performed a meta-analysis to evaluate whether this polymorphism is a risk factor for MI. METHODS Electronic databases (MEDLINE and EMBASE) were searched for all articles evaluating genetic polymorphisms of GPIIIa. For studies where acute coronary events were recorded in association with genetic analysis, pooled odds ratios (ORs) were calculated using fixed-effects and random-effects models. The primary outcome measure was MI, and a secondary analysis was also performed for acute coronary syndromes (ACS) more generally. FINDINGS 57 studies were eligible for statistical analysis and included 17,911 cases and 24,584 controls. Carriage of the PlA2 allele was significantly associated with MI (n = 40,692; OR 1.077, 95% CI 1.024-1.132; p = 0.004) but with significant publication bias (p = 0.040). The degree of association with MI increased with decreasing age of subjects (≤45 years old: n = 9,547; OR 1.205, 95% CI 1.067-1.360; p = 0.003) and with adjustment of data for conventional cardiovascular risk factors (n = 12,001; OR 1.240, 95% CI 1.117-1.376; p<0.001). There was a low probability of publication bias for these subgroup analyses (all p<0.05). CONCLUSIONS The presence of significant publication bias makes it unclear whether the association between carriage of the PlA2 allele and MI is true for the total population studied. However for younger subjects, the relative absence of conventional cardiovascular risk factors results in a significant association between carriage of the PlA2 allele and MI.

Abstract
BACKGROUND Coagulation and fibrinolysis are important in infections and systemic inflammatory response syndrome. Polymorphisms in plasminogen activator inhibitor-1 (PAI-1, SERPINE1) and tissue plasminogen activator (tPA, PLAT), such as PAI-1 (-675 4G/5G deletion/insertion) and tPA (Alu insertion/deletion [I/D]), are associated with strokes, myocardial infarctions, bacterial infections and septic shock severity, and trauma. Osteomyelitis is a mostly posttraumatic, Staphylococcal bone infection. PATIENTS AND METHODS tPA Alu (I/D) (rs4646972) and PAI-1 (4G/5G) (rs1799889) polymorphisms were studied by DNA amplification with polymerase chain reaction in 261 patients with osteomyelitis and in 299 matched blood donors. Plasma PAI-1/tPA complex was assessed by enzyme-linked immuosorbent assay. RESULTS II homozygotes (37.9% vs 19.1%) and I allele carriers (56.3% vs 46.3%) for the tPA Alu (I/D) polymorphism were significantly more frequent in osteomyelitis patients compared to controls (P < .001). II genotype carrier osteomyelitis patients had lower PAI-1/tPA complex levels compared to those with the D allele (P ≤ .04). There was no association between these genotypes and chronicity of osteomyelitis, post-traumatic etiology, or with a specific bacterial etiology. PAI-1 (4G/4G) homozygotes were not significantly different between osteomyelitis patients and controls (P = .1). CONCLUSIONS We report for the first time to our knowledge an association between the tPA Alu (I/D) polymorphism and susceptibility to bacterial osteomyelitis, perhaps by fibrinolysis dysfunction.

Abstract
INTRODUCTION To investigate whether t-PA Alu repeat insertion/deletion (I/D) and PAI-1 4G/5G genetic variations are associated with the risk of MI. METHODS We conducted a meta-analysis to assess the association between the t-PA I/D and PAI-1 4G/5G polymorphisms and risk of MI. We also performed subgroup analyses based on ethnicity (Caucasian, Asian, and African), gender and age. Forty one eligible studies including 12,461 cases and 14,993 controls were identified to evaluate the impact of PAI-1 4G/5G polymorphism on MI. Seven studies investigated the relationship between t-PA I/D and MI. RESULTS This meta-analysis revealed that the PAI-1 4G allele (4G/4G and 4G/5G genotype) was associated with an increased risk of MI compared with the 5G allele in the overall population (OR=1.094, 95% CI=1.021 - 1.172, p=0.011). The relative risks of MI for 4G/4G genotype was increased when compared to 5G/5G genotype and 5G allele, with odds ratio at 1.157 (95% CI 1.015 - 1.320, p=0.029) and 1.126 (95% CI =1.015 - 1.249, p=0.025). However, the results show that the 4G/5G polymorphism risk for MI was not associated with ethnicity stratification as Caucasian, Asian or African population. No substantial differences in the genotype distributions were observed in the MI group and control group along the lines of gender and age. After multivariable analysis t-PA I/D polymorphism showed no consistent association with MI. CONCLUSIONS This study suggests that the 4G/5G polymorphism of PAI-1 may be a risk factor for MI in overall populations.

Abstract
Background The polymorphism of plasminogen activator inhibitor-1 (PAI-1) 4G/5G gene has been indicated to be correlated with coronary artery disease (CAD) susceptibility, but study results are still debatable. Objective and Methods The present meta-analysis was performed to investigate the association between PAI-1 4G/5G gene polymorphism and CAD in the Chinese Han population. A total of 879 CAD patients and 628 controls from eight separate studies were involved. The pooled odds ratio (OR) for the distribution of the 4G allele frequency of PAI-1 4G/5G gene and its corresponding 95% confidence interval (CI) was assessed by the random effect model. Results The distribution of the 4 G allele frequency was 0.61 for the CAD group and 0.51 for the control group. The association between PAI-1 4G/5G gene polymorphism and CAD in the Chinese Han population was significant under an allelic genetic model (OR = 1.70, 95% CI = 1.18 to 2.44, P = 0.004). The heterogeneity test was also significant (P<0.0001). Meta-regression was performed to explore the heterogeneity source. Among the confounding factors, the heterogeneity could be explained by the publication year (P = 0.017), study region (P = 0.014), control group sample size (P = 0.011), total sample size (P = 0.011), and ratio of the case to the control group sample size (RR) (P = 0.019). In a stratified analysis by the total sample size, significantly increased risk was only detected in subgroup 2 under an allelic genetic model (OR = 1.93, 95% CI = 1.09 to 3.35, P = 0.02). Conclusions In the Chinese Han population, PAI-1 4G/5G gene polymorphism was implied to be associated with increased CAD risk. Carriers of the 4G allele of the PAI-1 4G/5G gene might predispose to CAD.
