Taha M, Ibrahim MMM, Sedrak H. Association of epistatic effects of MTHFR, ACE, APOB, and APOE gene polymorphisms with the risk of myocardial infarction and unstable angina in Egyptian patients. Gene 2024; 895:147976. [PMID: 37952748 DOI: 10.1016/j.gene.2023.147976] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Revised: 10/29/2023] [Accepted: 11/08/2023] [Indexed: 11/14/2023]
Abstract
Despite remarkable discoveries in the genetic susceptibility of coronary artery disease (CAD), a large part of heritability awaits identification. Epistasis or gene-gene interaction has a profound influence on CAD and might contribute to its missed genetic variability; however, this impact was largely unexplored. Here, we appraised the associations of gene-gene interactions and haplotypes of five polymorphisms, namely methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C, angiotensin converting enzyme (ACE) insertion/deletion (I/D), apolipoprotein B (APOB) R3500Q, and apolipoprotein E (APOE) ε4 with the risk of myocardial infarction (MI) and unstable angina (UA). Gene-environment interactions with traditional risk factors and clinical data were also scrutinized. This study recruited 100 MI, 50 UA patients, and 100 apparently healthy controls. Logistic regression models were employed in association analyses. We remarked that the single locus effect of individual polymorphisms was relatively weak; however, a magnified effect of their combination via gene-gene interaction may predict MI risk after adjustment for multiple comparisons. Only MTHFR C677T, ACE I/D, and APOB R5300Q were associated with the risk of UA, and the ACE I/D-R3500Q interaction posed a decreased UA risk. APOB R3500Q was in strong linkage disequilibrium with MTHFR C677T, ACE I/D, and APE ε4 polymorphisms. The TCDGε3, CADGε4, and TADGε4-C677T-A1298C-ACE I/D-R3500Q-APOE haplotypes were associated with escalating MI risk, while the CDG or CIG-C677T-ACE I/D-R3500Q haplotype was highly protective against UA risk compared to controls. Interestingly, the CADGε4 and CAIGε3 haplotypes were strongly associated with the presence of diabetes and hypertension, respectively in MI patients; both haplotypes stratified patients according to the ECHO results. In UA, the CDG haplotype was negatively associated with the presence of diabetes or dilated heart. Conclusively, our results advocate that a stronger combined effect of polymorphisms in MTHFR, ACE, APOB, and APOE genes via gene-gene and gene-environment interactions might help in risk stratification of MI and UA patients.

Abstract
Background Myocardial infarction (MI) remains the leading cause of death and disability among cardiovascular diseases worldwide. Studies show that elevated low-density lipid protein cholesterol (LDL-C) levels confer the highest absolute risk of MI, and Apolipoprotein E (ApoE) is implicated in regulating levels of triglycerides (TGs), cholesterol, and LDL-C. Our study aimed to evaluate the association between APOE polymorphism and MI, and to provide evidence for the etiology of MI. Methods Case–control studies on the association between APOE polymorphisms and the risk of myocardial infarction were included by searching PubMed, Web of Science, and CNKI, and this meta-analysis was written in accordance with PRISMA guideline statement. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using either random-effects or fixed-effects models by R software. Results A total of 33 eligible articles involving 13,706 cases and 14,817 controls were finally selected. The pooled analysis based on the total eligible articles showed that the risk of MI was associated with ApoE epsilon 2 and epsilon 4 alleles. The results showed that patients with MI had a low frequency of the ε2 allele (OR 0.74, 95% CI 0.64–0.86) and a high frequency of the ε4 allele (OR 1.24, 95% CI 1.09–1.42). Conclusions APOE ε2-involved genotypes may be protective factors for MI; in contrast, ε4-involved genotypes (ε4/ε3 vs. ε3/ε3, and ε4/ε4 vs. ε3/ε3) may be risk factors for MI.

Abstract
BACKGROUND Numerous reports investigated the involvement of apolipoprotein E (APOE) polymorphisms with elevated risk of type 2 diabetes mellitus (T2DM) and obesity. The principal objective of this study is to assess the contribution of APOE polymorphisms (rs429358 and rs7412) with the risk of T2DM and obesity. SUBJECTS AND METHODS This work was designed involving 400 participants [100 healthy controls, 100 T2DM patients, 100 obese patients, and 100 T2DM + obese patients]. Genomic deoxyribonucleic acid (DNA) of the APOE polymorphisms was characterized using the PCR-RFLP assay. RESULTS The common predominant genotype of the study population is the APOE Ɛ3/Ɛ3 [T2DM patients (46%), obese patients (52%), T2DM + obese patients (37%), and healthy controls (58%)]. The frequencies of the APOE Ɛ4/Ɛ4 genotype and the APOE*Ɛ4 allele were significantly elevated among T2DM patients (p-value < 0.05). Additionally, the frequencies of the APOE Ɛ2/Ɛ2 genotype and the APOE*Ɛ2 allele were significantly increased among obese patients (p-value < 0.05). Moreover, the frequencies of the APOE Ɛ2/Ɛ2 genotype, APOE*Ɛ2 allele, APOE Ɛ4/Ɛ4 genotype, and APOE*Ɛ4 allele were statistically significant among T2DM + obese patients (p-value < 0.05). CONCLUSIONS APOE*Ɛ2 and APOE*Ɛ4 alleles were considered as independent risk factor among T2DM + obese patients. Furthermore, the APOE*Ɛ2 allele was correlated with elevated risk of obesity, while the APOE*Ɛ4 allele was correlated with elevated risk of T2DM.

Abstract
Similar to dementia, the risk for developing type 2 diabetes mellitus (T2DM) increases with age, and T2DM also increases the risk for dementia, particularly Alzheimer's disease (AD). Although T2DM is primarily a peripheral disorder and AD is a central nervous system disease, both share some common features as they are chronic and complex diseases, and both show involvement of oxidative stress and inflammation in their progression. These characteristics suggest that T2DM may be associated with AD, which gave rise to a new term, type 3 diabetes (T3DM). In this study, we searched for matching peripheral proteomic biomarkers of AD and T2DM based in a systematic review of the available literature. We identified 17 common biomarkers that were differentially expressed in both patients with AD or T2DM when compared with healthy controls. These biomarkers could provide a useful workflow for screening T2DM patients at risk to develop AD.

Abstract
Background Diabetic nephropathy (DN) contributes to end-stage renal failure. Microvascular injury resulted from reactive oxygen species is implicated in the pathogenesis of DN. Genetic polymorphism of Apolipoprotein E (APOE) influences the antioxidative properties of the protein. The relationship of APOE polymorphism with the risks of nephropathy in type 2 diabetes (T2DN) remains elusive. Methods An up-to-date meta-analysis was conducted on the basis of studies selected from PubMed, WanFang database, Embase, Vip database, Web of Science, Scopus, and CNKI database. Results A total of 33 studies conferring 3266 cases and 3259 controls were selected on the basis of criteria of inclusion and exclusion in this meta-analysis. For APOE alleles, the pooled odds ratio (OR) of ε2 vs. ε3 was 1.89 (95% confidence intervals [95% CI]: 1.49–2.38, P < 0.0001). With regard to APOE genotypes, ε2/ε2, ε2/ε3, and ε2/ε4 increased the risk of T2DN (ε2/ε2 vs. ε3/ε3: OR = 2.32, 95% CI: 1.52–3.56, P = 0.0001; ε2/ε3 vs. ε3/ε3: OR = 1.97, 95% CI: 1.50–2.59, P<0.0001; ε2/ε4 vs. ε3/ε3: OR = 1.69, 95% CI: 1.18–2.44, P = 0.0046). Conclusions This meta-analysis found that the APOE ε2 allele and the ε2-involved genotypes (ε2/ε2, ε2/ε3, and ε2/ε4) are the risk factors of T2DN.

Abstract
Background Glucagon-like peptide-1 (GLP-1), a potent and selective agonist for the GLP-1 receptor, ameliorates the symptoms of diabetes through stimulation of insulin secretion. Exenatide is a potent and selective agonist for the GLP-1 receptor. Cell adhesion molecules are members of the immunoglobulin superfamily and are involved in synaptic rearrangements in the mature brain. Material/Methods The present study demonstrated the effects of exenatide treatment (0.1 μg/kg, subcutaneously, twice daily for 2 weeks) on the gene expression levels of cell adhesion molecules, neural cell adhesion molecule (NCAM), intercellular cell adhesion molecule (ICAM), and vascular cell adhesion molecule (VCAM) in the brain tissue of diabetic BALB/c male mice by real-time quantitative polymerase chain reaction (PCR). Diabetes was induced by streptozotocin/nicotinamide (STZ-NA) injection to male mice. Results The results of this study revealed that hippocampal gene expression of NCAM, ICAM, and VCAM were found to be up-regulated in STZ-NA-induced diabetic mice compared to those of controls. A significant decrease in the gene expression levels of NCAM, ICAM, and VCAM were determined after 2 weeks of exenatide administration. Conclusions Cell adhesion molecules may be involved in the molecular mechanism of diabetes. Exenatide has a strong beneficial action in managing diabetes induced by STZ/NA by altering gene expression of NCAM, ICAM, and VCAM.

Abstract
Obstructive sleep apnea (OSA), a condition with important implications for hypertension, diabetes, and cardiovascular disease, has been less researched for diabetes-associated microvascular disease. Such research is particularly important for developing countries (in particular, China and India), which are showing rapidly increasing prevalence of obesity, diabetes, and diabetic nephropathy (DN). In particular, independent association between OSA and DN needs more research inputs, keeping commonalty of risk factor profile for both diseases in mind. Finally, although weight loss remains the most effective strategy for OSA and also to some extent for DN, whether treatment with continuous positive airway pressure improves DN, similar to its positive effects on insulin resistance and glucose metabolism, remains to be established.

Abstract
Background As an important factor causing end-stage renal disease, diabetic nephropathy is correlated with low-grade chronic inflammation and immune system activation. This study aimed to investigate the protective function of puerarin on the kidneys of diabetic rats. Material/Methods A cohort of healthy male SD rats (7 weeks old) were randomly divided into a control group, a model group, and a puerarin treatment group with high (H), moderate (M), and low (L) dosage. After streptozotocin induction, puerarin was applied via intragastric administration for 8 consecutive weeks with dosages of 0.25, 0. 5 and 1.0 mg/(kg·d) for L, M, and H groups, respectively. Fasting blood glucose (BG), creatinine (Scr), urea nitrogen (BUN), and urine albumin excretion rate (UAER) were measured, along with morphological observation of renal cells. The expression of intracellular adhesion molecule 1 (ICAM-1) and tumor necrosis factor α (TNF-α) was determined using immunohistochemical (IHC) staining, while renal cortex cell apoptosis was assayed by in situ end-labeling method. Results Model rats had significantly elevated levels of BG, Scr, BUN, and UAER compared to controls (p<0.05). All these increases were partially but significantly suppressed by puerarin (p<0.05), which also caused marked improvement of histopathological damages. Puerarin at each dosage significantly eliminated elevations of ICAM-1 and TNF-α levels in model rats (p<0.05), and decreased apoptotic indexes of renal cortex cells (p<0.05). Conclusions Early-stage renal damages can be significantly improved by puerarin, possibly via its suppression of ICAM-1 and TNF-α expression in diabetic rat kidneys.

Abstract
Background Studies have assessed the association between Interleukin-10 (IL-10) -1082A/G polymorphism and diabetic nephropathy (DN) risk, but the results were inconclusive and contradictory. Therefore, we performed a meta-analysis to investigate the association between IL10-1082A/G polymorphism and DN risk. Material/Methods All relevant studies were searched by using PubMed and EMBASE. Data were extracted by 2 authors independently. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were calculated. Results Nine case-control studies with 4165 subjects were included in this meta-analysis. We found that IL10-1082A/G polymorphism was significantly associated with an increased DN risk (OR=1.21; 95% CI 1.07–1.37; P=0.002). In the subgroup analysis by race, both Caucasians and Asians with IL10-1082A/G polymorphism showed increased DN risk (OR=1.25; 95% CI 1.03–1.52; P=0.03 and OR=1.25; 95% CI 1.04–1.49; P=0.02), respectively. When we deleted the study without diabetes type, the result was not altered (OR=1.21; 95% CI 1.02–1.44; P=0.03). In the subgroup analysis by sample size, both studies with large sample size and studies with small sample size showed increased DN risk (OR=1.16; 95% CI 1.02–1.31; P=0.02 and OR=1.50; 95% CI 1.14–1.98; P=0.004), respectively. Conclusions This meta-analysis confirmed that IL10-1082A/G polymorphism might contribute to the susceptibility for DN.
