[PMID: 38034901 PMCID: PMC10683650 DOI: 10.2147/ijgm.s440103] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Accepted: 11/12/2023] [Indexed: 12/02/2023] Open
Abstract
Background Common polymorphisms within the apolipoprotein E (APOE) gene are rs429358 and rs7412, which result in three major alleles (ɛ2, ɛ3, and ɛ4) and six genotypes (E2/E2, E2/E3, E3/E3, E3/E4, E4/E4, and E2/E4). Although APOE gene polymorphisms have been suggested to be associated with the development of diabetic nephropathy (DN), their potential association remains unclear in different regions. This study aims to unveil the genetic effects of APOE gene polymorphisms on DN susceptibility and serum lipid profiles in southern Chinese population. Methods A total of 306 DN patients and 483 type 2 diabetic patients as controls were included in the study. The APOE gene polymorphisms were analyzed by polymerase chain reaction (PCR) microarray gene chip. Relevant medical records and information of these participants were collected. Results There were statistically significant differences (p < 0.05) in gender, SBP, hypertension, hyperuricemia, UTP, TG and HDL-C between DN patients and controls. DN patients exhibited a higher frequency of the ε2 allele and E2/E3 genotype than controls (p < 0.001). Logistic regression analysis indicated that the ε2 allele and E2/E3 genotype were independent risk factors (adjusted OR: 3.237, 95% CI: 1.789-5.854, p < 0.001; adjusted OR: 3.453, 95% CI: 1.873-6.368, p < 0.001), while the ε3 allele or E3/E3 genotype might serve as protective role (adjusted OR: 0.395, 95% CI: 0.255-0.612, p < 0.001) for development of DN. Conclusion Our study indicates a correlation between APOE polymorphisms and DN in the southern Chinese Hakka population. Specifically, individuals carrying the APOE ε2 allele and E2/E3 genotype are at a higher risk of developing DN. Conversely, those with the APOE ε3 allele and E3/E3 genotype have a lower risk of DN in southern Chinese population.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:5906244. [PMID: 34858508 PMCID: PMC8632459 DOI: 10.1155/2021/5906244] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Revised: 10/27/2021] [Accepted: 10/27/2021] [Indexed: 01/15/2023]
Abstract
Objective To study the efficacy of restricting dietary protein intake combined with Buyang Huanwu decoction in treating diabetic nephropathy (DN) and its effect on patients' inflammatory factor levels. Methods The medical data of 150 DN patients treated in Wuhan No.1 Hospital (June 2018—May 2021) were retrospectively analyzed. All patients received regular therapy, those who received the intervention of restricting dietary protein intake were included in the control group (n = 75), and on this basis, those treated with Buyang Huanwu decoction were included in the experimental group (n = 75), so as to scientifically evaluate their efficacy and inflammatory factor levels after treatment. Results The patients' general information was not statistically different between the two groups (P > 0.05); after treatment, the experimental group gained remarkably higher marked effective rate and total effective rate of treatment than the control group (P < 0.05); the inflammatory factor levels of all patients were obviously better than before (P < 0.05), and the levels of TNF-α, IL-2, IL-8, IL-4, and IL-10 were obviously lower in the experimental group than in the control group (P < 0.05); the levels of fasting blood glucose, 2 h postprandial blood glucose, and glycosylated hemoglobin of all patients were remarkably lower than before (P < 0.05), but with no significant between-group difference (P > 0.05); the renal function indexes of all patients were better than before, and between the two groups, the levels of 24 h microalbuminuria, 24 h urine protein excretion, and serum creatinine were obviously lower and the glomerular filtration rate was significantly higher in the experimental group (P all <0.05), and the patients' traditional Chinese medicine (TCM) symptom scores were remarkably lower in the experimental group (P < 0.05). Conclusion Jointly applying Buyang Huanwu decoction on the basis of restricting dietary protein intake can effectively promote the clinical efficacy of DN, which is conducive to adjusting the inflammatory factor levels, promoting the patients' renal function, and alleviating the clinical symptoms.

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
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
PURPOSE This study was aimed to study the hypothesis that forkhead box O1 (FOXO1) gene rs17446614 and rs17592236 single nucleotide polymorphisms (SNPs) influenced the development of diabetic nephropathy (DN). METHODS This study included 138 DN patients and 149 healthy controls. Controls were matched with the patients in age and gender. The method of polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP) was used to detect FOXO1 gene polymorphisms. Haploview software was conducted to analyze the linkage disequilibrium and haplotypes of FOXO1 gene polymorphisms. Relative risk of DN was expressed by odds ratios (ORs) and 95% confidence intervals (95% CIs), then the results were adjusted by clinical characteristics of the study subjects using logistic regression analysis. Subgroup analysis was performed according to gender. RESULTS AA genotype of rs17446614 SNPs was significantly associated with the risk of DN (P = .037, adjusted OR = 5.412, 95% CI = 1.103-26.559), especially in female (OR = 8.700, 95% CI = 1.008-75.062, P = .021). FOXO1 rs17446614 A allele positively associated with the development of DN (P = .027, adjusted OR = 1.680, 95% CI = 1.060-2.662), particularly in women (OR = 2.003, 95% CI = 1.070-3.749, P = .028). A-C haplotype formed by FOXO1 gene rs17446614 and rs17592236 SNPs was significantly associated with the increased risk of DN (P = .011, OR = 1.850, 95% CI = 1.146-2.986). CONCLUSION FOXO1 gene rs17446614 SNP, and the A-C haplotype of rs17446614 and rs17592236 polymorphisms were risk factors for the development of DN.
