Role of Uncoupling Protein 2 Gene Polymorphisms on the Risk of Ischemic Stroke in a Sardinian Population. Life (Basel) 2022; 12:life12050721. [PMID: 35629388 PMCID: PMC9147365 DOI: 10.3390/life12050721] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 05/02/2022] [Accepted: 05/09/2022] [Indexed: 12/05/2022] Open
Abstract
The mitochondrial uncoupling protein 2 (UCP2) acts as an anion transporter and as an antioxidant factor able to reduce the reactive oxygen species level. Based on its effects, UCP2 prevents the membrane lipids, proteins, and DNA damage while preserving normal cellular functions. Many variants have been identified within the human UCP2. Some of them were associated with a higher risk of obesity, diabetes and cardiovascular diseases in different populations. UCP2 appears a suitable candidate also for the risk of ischemic stroke. In the current study, we investigated the possible association between few variants of UCP2 (rs659366, rs660339, rs1554995310) and the risk of ischemic stroke in a genetically homogenous cohort of cases and controls selected in Sardinia Island. This population has been previously analysed for other candidate genes. A total of 250 cases of ischemic stroke and 241 controls were enrolled in the study. The allelic/genotypic distribution of the 3 UCP2 variants was characterized and compared among cases and controls. The results of our study confirmed known risk factors for ischemic stroke: age, history of smoking, hypertension, hypercholesterolemia, and atrial fibrillation. No association was found between the 3 UCP2 variants and the risk of ischemic stroke in our Sardinian cohort.

Abstract
Ischemic stroke (IS) is a severe neurological disease and a major cause of death and disability throughout the world. A long non-coding (lnc)RNA, transcription factor (TF) and gene can form a lncRNA-mediated regulatory triplet (LncMRT), which is a functional network motif that regulates numerous aspects of human diseases. However, systematic identification and molecular characterization of LncMRTs and their roles in IS has not been carried out. In the present study, a global LncMRT network was constructed and the topological features were characterized based on experimentally verified interactions. An integrated approach was developed to identify significantly dysregulated LncMRTs in peripheral blood mononuclear cells of IS and these dysregulated LncMRT networks exhibited specific topological characteristics and a closer network structure than the global LncMRT network that was constructed. The variation of the risk score for LncMRTs indicated that there were multiple dysregulated patterns of LncMRTs in IS. Numerous core clusters were identified from dysregulated LncMRT networks and these core clusters could distinguish IS patient and matched control samples. Finally, functional analyses demonstrated that LncMRTs associated with IS participated in the regulation of the phosphatidylinositol 3-kinase/protein kinase B signaling pathway. In conclusion, the roles of the LncMRTs in IS were elucidated, which could be beneficial for understanding IS pathogenesis and treatment.

Abstract
Background The association between cholesterol ester transfer protein (CETP) Taq IB polymorphism and coronary artery disease (CAD) has been studied in different populations. Acute coronary syndrome (ACS) is a group of clinical symptoms within acute myocardial ischemia, including unstable angina (UA) and myocardial infarction (MI). Because there are no data reported in the literature concerning the cholesteryl ester transfer protein (CETP) Taq IB polymorphism in Egyptians, our study aimed to investigate the frequency of different CETP Taq IB genotypes in Egyptian patients with ACS and in healthy control individuals. Methods The current study was conducted with 70 hospitalized patients who had been diagnosed with ACS and 30 controls. We used real-time polymerase chain reaction (RT-PCR) to determine CETP Taq IB in individuals with different genotypes. Results The frequency of the GA genotype was significantly lower in UA patients, compared with the control group ( P <.05). Conclusions The frequency of the CETP Taq IB genotypes and alleles in all groups was similar to that in other ethnic groups. Individuals with the Taq IB GA genotype may have a lower risk of UA.

Associations of Cholesteryl Ester Transfer Protein TaqIB Polymorphism with the Composite Ischemic Cardiovascular Disease Risk and HDL-C Concentrations: A Meta-Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2016; 13:ijerph13090882. [PMID: 27608031 PMCID: PMC5036715 DOI: 10.3390/ijerph13090882] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/12/2016] [Revised: 08/18/2016] [Accepted: 08/30/2016] [Indexed: 11/17/2022]
Abstract
BACKGROUND Previous studies have evaluated the associations between the cholesteryl ester transfer protein (CETP) TaqIB polymorphism (rs708272), the risk of developing composite ischemic cardiovascular disease (CVD) and the concentration of high-density lipoprotein cholesterol (HDL-C), but results remain controversial. The objective of this study was to investigate whether a relationship exists between these factors. METHODS We conducted a meta-analysis of available studies to clarify the associations of the CETP TaqIB polymorphism with HDL-C concentration and the composite ischemic CVD risk in both Asians and Caucasians. All statistical analyses were done with Stata 12.0. RESULTS Through utilization of the Cochrane Library, Embase, PubMed, Web of Science, Springer, China Science and Technology Journal Database, China National Knowledge Infrastructure, Google Scholar, and Baidu Library, a total of 45 studies from 44 papers with 20,866 cases and 21,298 controls were combined showing a significant association between the CETP TaqIB variant and composite ischemic CVD risk. Carriers of allele TaqIB-B1 were found to have a higher risk of composite ischemic CVD than non-carriers: OR = 1.15, 95% CI = 1.09-1.21, p < 0.001. Meanwhile, 28 studies with 23,959 subjects were included in the association between the CETP TaqIB polymorphism and the concentration of HDL-C. RESULTS suggested that carriers of the B1B1 genotype had lower concentrations of HDL-C than those of the B2B2 genotype: SMD = 0.50, 95% CI = 0.36-0.65, p < 0.001. CONCLUSIONS The synthesis of available evidence demonstrates that the CETP TaqIB polymorphism protects against composite ischemic CVD risk and is associated with a higher HDL-C concentration in both Asians and Caucasians.

Abstract
Genetic factors contribute to the risk of ischemic stroke (IS). The phosphodiesterase-4D (PDE4D) and the 5-lipoxygenase activating protein (ALOX5AP) genes were identified as contributors to stroke in an Icelandic population. In an attempt to better define the contributory role of PDE4D and ALOX5AP genes to the risk of IS in humans, we carried out the present association study in a well-characterized, earlier published, genetically homogenous population from the island of Sardinia, Italy. In this cohort, including 294 cases and 235 controls, age, hypertension, hypercholesterolemia, and atrial fibrillation represent risk factors for IS. The PDE4D gene was evaluated by four single nucleotide polymorphisms (SNP32, SNP45, SNP83, SNP87) and by the microsatellite AC008818-1; the ALOX5AP gene was characterized by three SNPs (SG13S32, SG13S89, ALO2A). The results of our study provide no evidence of association between any single PDE4D and ALOX5AP gene variant with the risk of IS in the Sardinian cohort. Haplotype analysis, including that constructed with allele 0 of microsatellite AC008818-1 and SNP45 of the PDE4D gene, was also negative. In conclusion, we found no evidence of association between PDE4D and ALOX5AP genes and the risk of IS in a genetically homogenous population from Sardinia.

Abstract
Advances in the Genetic Basis of Ischemic StrokeAs one of the leading causes of death within both the developed and developing world, stroke is a world-wide problem. About 80% of strokes are ischemic. It is caused by multiple genetic factors, environmental factors, and interactions among these factors. There is a long list of candidate genes that have been studied for a possible association with ischemic stroke. Among the most widely investigated genes are those involved in haemostasis, inflammation, nitric oxide production, homocysteine and lipid metabolism, renin-angiotensin-aldosterone system. Combined link-age/association studies have demonstrated that genes encoding PDE4D and ALOX5AP confer risk for stroke. We review the studies of these genes which may have potential application on the early diagnosis, prevention and treatment ischemic stroke patients.
