Exp Ther Med 2017; 15:2109-2119. [PMID: 29434813 DOI: 10.3892/etm.2017.5641] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2017] [Accepted: 11/11/2017] [Indexed: 11/05/2022] Open
Abstract
The objective of the present study was to investigate the association between recurrent implantation failure (RIF) and vascular endothelial growth factor (VEGF) gene polymorphisms that are associated with various female infertility disorders. A total of 116 women diagnosed with RIF and 218 control subjects were genotyped for the VEGF -2578C>A, -1154G>A, -634C>G and 936C>T polymorphisms using a polymerase chain reaction-restriction fragment length polymorphism assay. The VEGF -2578AA genotype was associated with an increased prevalence (≥4) of RIF [adjusted odds ratio (AOR)=2.77; 95% confidence interval (CI)=1.10-7.02; P=0.031], whereas the VEGF -634CG+GG genotype was associated with an increased incidence of total RIF (AOR=2.03; 95% CI=1.02-4.05; P=0.044) and ≥4 RIF (AOR=3.16; 95% CI=1.19-8.37; P=0.021). The results of the haplotype analysis indicated that -2578A/-1154A/-634G/936C (AOR=1.76; 95% CI=1.03-3.00; P=0.040 for total RIF and AOR=2.11; 95% CI=1.12-3.97; P=0.021 for ≥4 RIF) was associated with the occurrence of RIF. In addition, it was revealed that there was a significant difference in serum prolactin level associated with the VEGF -634C>G polymorphism (P=0.013). Therefore the findings of the present study indicate that the VEGF -2578AA genotype, -634G allele and -2578A/-1154A/-634G/936C haplotype may be genetic markers for susceptibility to RIF. However, further studies on VEGF promoter polymorphisms that include an independent randomized-controlled population are required to confirm these results.

Abstract
AIMS The genetics of folate metabolism is one of the most significant mechanisms influencing fetal growth and may underlie some cases of unexplained recurrent miscarriage. Reduced folate carrier 1, encoded by the SLC19A1 gene, is a transporter of folate. Folate deficiency and elevated levels of homocysteine could be disadvantageous for the female reproductive system health. Thus, the balance between homocysteine and folate status can be used to measure the risk of recurrent pregnancy loss. METHODS The purpose of this study was to determine the association between -43T>C, 80G>A, and 696C>T polymorphisms of the SLC19A1 gene in 147 women who had unexplained recurrent miscarriage in comparison with 150 healthy women. Amplification refractory mutation system-polymerase chain reaction was used to genotype the molecular polymorphisms of this gene. RESULTS The results indicated that the -43T>C single nucleotide of the SLC19A1 gene was significantly associated with a risk of recurrent miscarriage in Iranian women (p < 0.05). No significant association was observed for the other two polymorphisms. The haplotype frequency distribution of -43C/80G/696C, -;43C/80G/696T, -43C/80G, and 80G/696T was significantly different in patients than controls, which may represent a novel risk factor for idiopathic recurrent pregnancy loss. CONCLUSIONS Polymorphisms and haplotypes of the SLC19A1 gene can be considered risk factors for idiopathic recurrent pregnancy loss.

PLoS One 2015; 10:e0115295. [PMID: 25659099 PMCID: PMC4319782 DOI: 10.1371/journal.pone.0115295] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2014] [Accepted: 11/23/2014] [Indexed: 11/19/2022] Open
Abstract
Stroke is the second leading cause of death in the world and in South Korea. Ischemic stroke and silent brain infarction (SBI) are complex, multifactorial diseases influenced by multiple genetic and environmental factors. Moderately elevated plasma homocysteine levels are a major risk factor for vascular diseases, including stroke and SBI. Folate and vitamin B12 are important regulators of homocysteine metabolism. Reduced folate carrier (RFC), a bidirectional anion exchanger, mediates folate delivery to a variety of cells. We selected three known RFC-1 polymorphisms (-43C>T, 80A>G, 696T>C) and investigated their relationship to cerebral infarction in the Korean population. We used the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method to analyze associations between the three RFC-1 polymorphisms, disease status, and folate and homocysteine levels in 584 ischemic stroke patients, 353 SBI patients, and 505 control subjects. The frequencies of the RFC-1 -43TT, 80GG, and 696CC genotypes differed significantly between the stroke and control groups. The RFC-1 80A>G substitution was also associated with small artery occlusion and SBI. In a gene-environment analysis, the RFC-1 -43C>T, 80A>G, and 696T>C polymorphisms in the ischemic stroke group had combined effects with all environmental factors. In summary, we found that the RFC-1 -43C>T, 80A>G, and 696T>C polymorphisms may be risk factors for ischemic stroke.

Genetic association of five plasminogen activator inhibitor-1 (PAI-1) polymorphisms and idiopathic recurrent pregnancy loss in Korean women. Thromb Haemost 2013; 110:742-50. [PMID: 23903286 DOI: 10.1160/th13-03-0242] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2013] [Accepted: 07/03/2013] [Indexed: 11/05/2022]
Abstract
Plasminogen activator inhibitor-1 (PAI-1) is important for maintaining pregnancy. Aberrantly increased PAI-1 levels may contribute to thrombosis and inflammation, leading to pregnancy loss. This study investigated the association of PAI-1 polymorphisms (PAI-1 rs2227631 [-844G>A], rs1799889 [-675 4G/5G], rs6092 [43G>A], rs2227694 [9785G>A], and rs7242 [11053T>G]) with idiopathic recurrent pregnancy loss (RPL) in Korean women. We screened 308 RPL patients and 227 control participants for five PAI-1 polymorphisms. Genotyping of PAI-1 was performed by polymerase chain reaction-restriction fragment length polymorphism assay. PAI-1 4G4G and -844AA/4G4G/11053GG genotypes were associated with RPL. PAI-1 -844A/4G/43G/9785G/11053G haplotype was connected to hypofibrinolytic status (i.e. increased levels of plasma PAI-1, increased numbers of platelets, reduced prothrombin time, and reduced activated partial thromboplastin time). Moreover, PAI-1 11053TG+GG frequency was positively related to plasma homocysteine and urate levels, whereas -844AA frequency was associated with plasma folate concentrations according to ordinal logistic regression analysis. Based on these results, we propose that PAI-1 -844G>A, 4G/5G, and 11053T>G polymorphisms are markers of RPL.

Abstract
OBJECTIVE To investigate the association between one-carbon metabolism and recurrent pregnancy loss (RPL). One-carbon metabolism is important for maintaining pregnancy, and the enzymes codified by these genes are relevant to this metabolic pathway. DESIGN Case-control study. SETTING An urban university-based hospital in South Korea. PATIENT(S) A cohort of 353 RPL patients (3.09 ± 1.65 pregnancy losses) and 226 control subjects. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Genotyping was assessed by polymerase chain reaction-restriction fragment length polymorphism assay. We examined polymorphisms in four genes: methionine synthase (MTR); methionine synthase reductase (MTRR); methylenetetrahydrofolate dehydrogenase 1 (MTHFD1); and thymidylate synthase (TS). RESULT(S) The MTR 2756AA polymorphism was associated with RPL. Gene-gene interaction analysis revealed that the frequency of the MTR 2756A-TS 6-bp allele combination was significantly higher in RPL. CONCLUSION(S) Based on these results, we propose that the MTR 2756AA genotype and MTR 2756A-TS 6-bp allele combination are possible predisposing factors for RPL development in Korean women.

Abstract
OBJECTIVE To investigate whether kinase insert domain-containing receptor (KDR) gene polymorphisms are risk factors for recurrent spontaneous abortion (RSA) in Korean women. DESIGN Case-control study. SETTING University hospital. PATIENT(S) Three hundred twenty-seven idiopathic RSA patients and 230 controls with Korean ethnicity. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) The KDR -604T→C (rs2071559), 1192G→A (rs2305948), and 1719A→T (rs1870377) polymorphisms were assessed. RESULT(S) KDR -604TC and TC+CC genotypes were more prevalent in RSA patients than in controls (adjusted odds ratio [AOR] = 2.091 and 2.076, respectively). KDR -604TC+CC/1192GG, -604TC+CC/1719AA, and -604TC+CC/1719TA+TT combined genotypes exhibited higher frequencies in RSA patients (AOR = 2.422, 2.611, and 2.216, respectively). KDR -604C/1192G/1719A, -604C/1192G/1719T, -604C/1192G, -604C/1719A, and -604C/1719T haplotype frequencies were higher in RSA patients (OR = 1.778, 2.659, 2.089, 1.678, and 1.806, respectively), whereas -604T/1192G/1719A, -604T/1192G, and -604T/1719A haplotype frequencies were lower in RSA patients (OR = 2.422, 2.611, and 2.216, respectively). No association was found between RSA and KDR 1192G→A or 1719A→T. CONCLUSION(S) An association between the KDR -604T→C polymorphism and RSA was found in Korean women. Carriers of the -604C variant allele were more frequent among RSA patients than among controls, suggesting that KDR -604C may confer RSA risk. The association of 1719A→T with RSA that was found in Taiwanese Han women was not observed in Korean women.

Abstract
The objective was to investigate the association between idiopathic recurrent spontaneous abortion (RSA) and 3 SLC19A1 polymorphisms (-43T>C, 80G>A, and 696C>T). DNA from 269 patients with RSA and 125 controls were genotyped for the 3 SLC19A1 single nucleotide polymorphisms (SNPs) by polymerase chain reaction-restriction fragment length polymorphism. Homocysteine and folate levels of 100 patients with RSA were available for analysis. The combination genotypes of SLC19A1 -43TC/80GG, -43TC/80AA, and -43CC/80GA; 80GA/696TT, 80AA/696CC; and -43TC/696CC were less frequent in patients with RSA compared to controls (P < .05 for each). The -43C/80A/696 T and -43T/80G/696C haplotypes were more frequent in patients than controls, whereas -43T/80A/696C, -43C/80A/696C, -43C/80G/696C, -43C/80G/696T, and -43T/80G/696T haplotypes were less frequent in patients (P < .05 for each). The -43T/80G and 80A/696T haplotypes were more frequent in patients, while -43T/80A, -43C/80G, 80A/696C, 80G/696T, and -43C/696C haplotypes occurred less frequently in patients (P < .05 for each). The associations between idiopathic RSA occurrence and SLC19A1 -43T>C/80G>A/696C>T polymorphisms were identified and can be developed as biomarkers for RSA risk.
