Relationship between Arachidonate 5-Lipoxygenase-Activating Protein Gene and Peripheral Arterial Disease in Elderly Patients Undergoing General Surgery: A Retrospective Observational Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:1027. [PMID: 36673783 PMCID: PMC9858772 DOI: 10.3390/ijerph20021027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/10/2022] [Revised: 01/01/2023] [Accepted: 01/04/2023] [Indexed: 06/17/2023]
Abstract
Patients with peripheral arterial disease (PAD) are at a higher risk of developing postoperative complications. Arachidonate 5-lipoxygenase-activating protein (ALOX5AP) plays an important role in atherosclerosis pathogenesis. In this study, the relationship between PAD and several single nucleotide polymorphisms (SNPs) of ALOX5AP (rs17216473, rs10507391, rs4769874, rs9551963, rs17222814, and rs7222842) was investigated in elderly patients undergoing general surgery. The medical records of 129 patients aged > 55 years who underwent elective general surgery between May 2018 and August 2019 were retrospectively reviewed. The A/A in rs17216473, A/A in rs10507391, G/G in rs4769874, and A/A in rs9551963 were calculated as 0 points and the rest as 1 point to define the genetic risk score. The prevalence of PAD tended to increase with higher genetic risk scores (patients had less ALOX5AP gene polymorphism of A/A in rs17216473, A/A in rs10507391, G/G in rs4769874, or A/A in rs9551963) (p = 0.005). Multivariate logistic regression analysis revealed that the genetic risk score (p = 0.009) and age (p = 0.007) were positively correlated with the prevalence of PAD. Genetic polymorphisms of ALOX5AP and age were associated with the prevalence of PAD in this study.

Epigenetic regulation mechanism of DNA methylation and miRNAs on the expression of the ALOX5AP gene in patients with ischemic stroke. Exp Ther Med 2021; 22:1484. [PMID: 34765025 PMCID: PMC8576617 DOI: 10.3892/etm.2021.10919] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2020] [Accepted: 10/30/2020] [Indexed: 12/22/2022] Open
Abstract
5-lipoxygenase-activating protein (FLAP), encoded by the arachidonate 5-lipoxygenase-activating protein (ALOX5AP) gene, can adjust the biogenesis of proinflammatory leukotrienes to increase the adhesion and permeability of the vascular internal wall. Moreover, it participates in the process of atherosclerosis and is closely associated with ischemic stroke (IS). Accumulating evidence has shown that the expression levels of the ALOX5AP gene are upregulated in patients with IS. However, the mechanism of ALOX5AP action in IS remain elusive. The present study hypothesized that epigenetic regulation, including DNA methylation and microRNA (miR/miRNA) regulation, affects the expression levels of the ALOX5AP gene. Therefore, 200 patients with a first diagnosis of acute IS and 200 healthy control subjects were enrolled in the present study. Initially, the mRNA expression levels of the ALOX5AP gene were examined by reverse transcription-quantitative PCR. It was found that the mRNA levels of ALOX5AP gene in the IS group were significantly higher compared with controls (P<0.05). Subsequently, the methylation status of 17 CpG sites located in the promoter region of ALOX5AP was assessed by MethyTarget sequencing. However, the levels of methylation exhibited no significant differences between IS and control groups (P>0.05). Moreover, the expression levels of miR-335 and miR-495 were examined as two potential miRNAs targeting the ALOX5AP gene. The expression levels of miR-335 and miR-495 in the IS group were significantly lower compared with the control group (P<0.05). Finally, the luciferase assay results indicated that the luciferase activity of the experimental group following co-transfection of miRNA mimic and wild-type reporter gene plasmid was significantly lower compared with the other experimental groups (P<0.05), suggesting that miR-335 and miR-495 could specifically bind to the 3'-untranslated region of the ALOX5AP gene, thereby downregulating its expression. The present study provided preliminary evidence demonstrating that epigenetic regulation affects the expression of the ALOX5AP gene in patients with IS.

Abstract
Stroke is a major public health problem worldwide with a high burden of neurological disability and mortality. Long noncoding RNAs (lncRNAs) have attracted much attention in the past decades because of their newly discovered roles in pathophysiological processes in many diseases. The abundance of lncRNAs in the nervous system indicates that they may be part of a complex regulatory network governing physiology and pathology of the brain. In particular, lncRNAs have been shown to play pivotal roles in the pathogenesis of stroke. In this article, we provide a review of the multifaceted functions of lncRNAs in the pathogenesis of ischemic stroke and intracerebral hemorrhage, highlighting their promising use as stroke diagnostic biomarkers and therapeutics. To this end, we discuss the potential of stem cells in aiding lncRNA applications in stroke.

Abstract
A major problem of hemophilia A (HA) treatment is the development of factor VIII (FVIII) inhibitor, which usually occurs shortly after initiating replacement therapy. Several studies showed the correlation between inhibitor development and polymorphisms in inflammatory and immune response genes of HA patients; however, literature data are not available to prove this association in Iranian population. The aim of this study was to investigate a possible association between FVIII inhibitor formation and the polymorphisms of 16 inflammatory and immune response genes in Iranian severe HA patients (FVIII activity < 1%). This case-control study was performed on 55 patients with severe HA inhibitors and 45 samples without inhibitors from Iranian Comprehensive Hemophilia Care center. After extraction of whole genomic DNA from blood samples and design of primers for 16 genes, the genotyping was performed by Tetra primer ARMS PCR, and the validation of single nucleotide polymorphisms was determined by DNA sequencing. The data indicated that there was a significant association between inhibitor development, and F13A1 (TT), DOCK2 (CC& CT), and MAPK9 (TT) genotypes. Moreover, a considerably increased inhibitor risk carrying T, C, and T allele for F13A1, DOCK2, and MAPK9 genes was observed in patients with inhibitors, respectively. In contrast, there was no statistically significant difference between the genotypic and allelic frequencies for other genes in patients with inhibitors compared to patients without inhibitors. These results demonstrate that only polymorphisms in F13A1, DOCK2, and MAPK9 genes are associated with the risk of developing FVIII inhibitors in Iranian HA patients.

Abstract
BACKGROUND In recent years, there has been substantial research evaluating the relationship between arachidonate 5-lipoxygenase-activating protein (ALOX5AP) polymorphisms and ischemic stroke (IS). The objective of this study was to systematically review and analyze the existing evidence. METHODS A comprehensive search of major electronic databases for studies published between 1990 and 2018 was carried out. Data were synthesized as OR and 95% CI using fixed-effects and random-effects models. RESULTS A total of 30 studies were available for analysis. The aggregate sample size across all studies was 32,782 (16,294 cases and 16,488 controls). We found no association of the ALOX5AP rs10507391 (OR=1.03 for A allele vs T allele; 95% CI: 0.93-1.14; P=0.557), rs4769874 (OR=1.13 for A allele vs G allele; 95% CI: 1.00-1.28; P=0.050), rs9551963 (OR=1.03 for A allele vs C allele; 95% CI: 0.96-1.11; P=0.372), rs17222814 (OR=1.09 for A allele vs G allele; 95% CI: 0.96-1.24; P=0.195), rs17222919 (OR=0.89 for G allele vs T allele; 95% CI: 0.75-1.06; P=0.175), and rs4073259 (OR=1.20 for A allele vs G allele; 95% CI: 1.00-1.45; P=0.056) polymorphisms with IS risk. Haplotype analysis also did not yield significant findings for the HapA (rs17222814G-rs10507391T-rs4769874G-rs9551963A; OR=1.20; 95% CI: 0.91-1.56; P=0.192) and HapB (rs17216473A-rs10507391A-rs9315050A-rs17222842G; OR=1.11; 95% CI: 0.90-1.38; P=0.339) haplotypes. CONCLUSION Current evidence does not support an association of rs10507391, rs4769874, rs9551963, rs17222814, rs17222919, rs4073259, and HapA and HapB with IS risk.

Abstract
BACKGROUND Recent evidence suggests that long non-coding RNAs (lncRNAs) are key regulators in the pathological process of ischemic stroke (IS). Maternally expressed gene 3 (MEG3) was observed to be up-regulated in IS, acting as a competing endogenous RNA for miR-181b to regulate ischemic brain injury. The purpose of this study was to evaluate the association of tagSNPs in MEG3 (i.e., rs7158663 and rs4081134) and miR-181b rs322931 with IS risk. METHODS Genomic DNA was extracted from blood samples of 509 patients with IS and 668 healthy controls. Genotyping of MEG3 rs7158663, rs4081134, and miR-181b rs322931 was performed by TaqMan assay. The transcriptional activity was measured using the Dual-Luciferase Reporter Assay kit. RESULTS Single-site analysis revealed a significantly higher risk of IS being associated with miR-181b rs322931 CT and CT/TT genotypes (CT vs. CC: adjusted OR = 1.48, 95% CI: 1.13-1.95, P = 0.005; CT/TT vs. CC: adjusted OR = 1.52, 95% CI: 1.17-1.97, P = 0.002). Combined analyses revealed that combined genotypes (rs7158663 GG + rs322931 CT/TT and rs7158663 AG/AA + rs322931 CT/TT) increased IS risk compared to genotypes of rs7158663 GG + rs322931 CC. Stratification analyses showed that patients carrying miR-181b rs322931 CT/TT genotypes had higher levels of low-density lipoprotein cholesterol (LDL_C) (P = 0.01). Moreover, results from logistic regression analysis showed that rs322931 CT/TT genotypes were risk factors besides hypertension, total cholesterol, triglyceride, and LDL_C. Further dual-luciferase reporter assay showed that the rs322931 T allele had lower levels of luciferase activity than the rs322931 C allele. CONCLUSION These findings indicate that miR-181b rs322931 may singly or jointly contribute to the risk of IS.

Abstract
Long noncoding RNAs (lncRNAs) play crucial roles in the regulation of pathological process of ischemic stroke (IS) via affecting cell apoptosis, inflammation, cell death, and angiogenesis. LncRNA growth arrest-specific 5 (GAS5) was observed to be up-regulated in IS, acting as a competing endogenous RNA for miR-137 to mediate the Notch1 signaling pathway. In this study, we aimed to whether an insertion/deletion polymorphism (rs145204276) in the promoter of GAS5 was related to the risk of IS. The rs145204276 was genotyped using polymerase chain reaction (PCR)-polyacrylamide gel electrophoresis in 509 patients with IS and 668 healthy controls with frequencies matched to cases regarding age, gender, living area, and ethnicity. The GAS5 expression levels were determined using qPCR and relative luciferase activity was measured using the Dual Luciferase assay system. The presence of del/del genotype and del allele was associated with an increased risk of IS [del/del versus ins/ins: adjusted odds ratio (OR) = 2.06, 95% confidence interval (CI): 1.37-3.11; recessive model: adjusted OR = 2.07, 95% CI: 1.41-3.04; del versus ins: adjusted OR = 1.31, 95% CI: 1.08-1.57]. Results from logistic regression analysis identified risk factors for IS, including hypertension, total cholesterol, triglyceride, low-density lipoprotein cholesterol, and rs145204276 del/del genotype. Furthermore, patients carrying rs145204276 del/del genotype had significantly higher levels of GAS5 and cells transfected with rs145204276 del allele exhibited a larger increase in luciferase activity. These findings indicate that rs145204276 del allele exhibited a significant association with an increased IS susceptibility by elevating the transcriptional activity and subsequently enhancing the expression of lncRNA GAS5.

Abstract
Previous studies have shown that CpG-SNPs might have influence on gene function via allele-specific DNA methylation (ASM). However, association study between DNA methylation and the promoter CpG-SNPs in ALOX5AP gene with IS has not been reported. The present study aims to explore the relationship among CpG-SNPs, methylation levels, and messenger RNA (mRNA) expression levels of ALOX5AP gene. Firstly, we made a two-stage association study to identify a potential associated CpG-SNP (rs4073259) by SNaPshot genotyping approach (P = 0.015, OR = 0.672, 95% CI 0.487-0.927; P = 0.035, OR = 0.809, 95% CI 0.664-0.985, respectively). In addition, the methylation levels of 17 CpG sites located in the promoter of ALOX5AP were tested by MethylTarget sequencing. The methylation level of GG genotype carriers is significantly higher than those with the AG and AA genotypes (P < 0.05). And the GG genotype carriers with higher DNA methylation levels have a decreased mRNA expression levels of ALOX5AP (P < 0.05). Finally, we found that the G allele with higher methylation level has got a lower transcription activity than the A allele by luciferase assay (P = 0.000).The study provided evidence that IS-associated CpG-SNP rs4073259 may affect the expression level of ALOX5AP through allele-specific methylation and consequently the phenotype of the disease.

Abstract
Previous work has suggested that ischemic stroke (IS) may be more likely to occur in individuals with a genetic predisposition. In this study, we investigated the potential association of IS-relevant genetic risk factors with cardioembolic stroke (CES) in atrial fibrillation (AF) patients with low CHA2DS2-VaSc score. Genotyping was performed using the GenomeLab SNPstream genotyping platform for five IS-relevant SNPs (MMP-9 C1562T, ALOX5AP SG13S114A/T, MTHFR 677 C/T, FGB 455 G/A, and eNOS G298A) in 479 AF patients with CES and 580 age and sex-matched AF patients without CES. The multivariate analysis adjusted for potential confounders and demonstrated that FGB 455 G/A was independently associated with increased risk of CES in AF patients and the significance remained after Bonferroni correction in the additive, dominant, and recessive models with ORs of 1.548 (95% CI: 1.251–1.915, P = 0.001), 1.588 (95% CI: (1.226–2.057, P = 0.003), and 2.394 (95% CI: 1.357–4.223, P = 0.015), respectively. Plasma fibrinogen levels were significantly higher in patients with the A allele compared with patients with genotype of GG (3.29 ± 0.38 mg/dl vs. 2.87 ± 0.18 mg/dl, P < 0.001). We found for the first time that the A allele of FGB 455 G/A was a risk factor for CES in AF patients, probably by elevating the level of plasma fibrinogen.
