Cellular and molecular changes occur during aging, decreasing organ function. The aging process was measured by several biomarkers, including DNA methylation (DNAm), an epigenetic change regulating gene expression, which is highly accurate at predicting biological age. DNAm is heritable and therefore varies between different populations. To assess blood DNA methylation changes as epigenetic clocks in the male and female Egyptian population. Pyrosequencing was used to measure the methylation of nine CpG sites in blood samples from 100 healthy Egyptians (18–69 years) using a cross-sectional study. Two age predicted models based on the ELOVL2 gene were compared in three age categories and correlated in all age groups despite decreasing accuracy with increasing age. The mean absolute deviation (MAD) using the 1st and 2nd age predicted models for 18–40 years was 1.06 and 2.7, respectively; for 41–60 years, it was 4.4 and 3.8, respectively; and for > 60 years, it was 7.7 and 7.0, respectively. No significant differences in DNA methylation were found between the sexes. DNA methylation of the ELOVL2 gene can be used as an accurate biomarker for age estimation. Additionally, this method has the potential to be more accurate than traditional methods of age estimation.
衰老过程中会发生细胞和分子变化,降低器官功能。衰老过程是通过几种生物标志物来测量的,其中包括 DNA 甲基化(DNAm),这是一种调节基因表达的表观遗传变化,在预测生物年龄方面具有很高的准确性。DNAm 具有遗传性,因此在不同人群之间存在差异。目的是评估作为表观遗传时钟的埃及男性和女性人群的血液 DNA 甲基化变化。通过一项横断面研究,对 100 名健康埃及人(18-69 岁)的血液样本中 9 个 CpG 位点的甲基化情况进行了热释光测序测量。在三个年龄组中比较了两种基于 ELOVL2 基因的年龄预测模型,尽管准确性随着年龄的增加而降低,但它们在所有年龄组中都具有相关性。使用第一和第二年龄预测模型得出的平均绝对偏差(MAD),18-40 岁分别为 1.06 和 2.7;41-60 岁分别为 4.4 和 3.8;大于 60 岁分别为 7.7 和 7.0。男女之间的 DNA 甲基化没有明显差异。ELOVL2 基因的 DNA 甲基化可作为准确估算年龄的生物标志物。此外,这种方法有可能比传统的年龄估计方法更准确。

According to the increasing trend of COPD, the timely diagnosis and treatment of the disease can reduce the high costs to the health systems. Therefore, by biological calculation methods, signaling pathways and genes involved in this disease can be obtained and used to design drugs and other treatment methods. By using biological calculations, we determined that curcumin can affect this disease and its genes and signaling pathways. Our goal in this study was to find the genes by which curcumin exerts its effect and can maintain the function of corticosteroids against oxidizing agents. By finding the genes, it is possible to find precisely the pathways by which curcumin works, which can be used to design other drugs that cause these pathways and minimize their side effects. This study considers healthy samples (with/without curcumin) and oxygen-free radicals (with/without curcumin). Finally, statistical algorithms extract meaningful genes as effective biomarkers to investigate curcumin's effects and signaling pathways in COPD. The results show that the genes finally obtained as the most critical genes confirmed by the literature are effective in COPD. Finally, curcumin was input in SwissTargetPrediction to identify potential protein receptors. We used LigPlot+ software to visualize the receptor–ligand binding result provided by iGEMDOCK. The data showed that the most significant genes in each group have been confirmed in other studies to be effective in this disease, and protein–protein interaction networks can be established between them to investigate their roles.
鉴于慢性阻塞性肺病的发病率呈上升趋势,及时诊断和治疗该疾病可以降低医疗系统的高昂成本。因此,通过生物学计算方法,可以获得与该疾病相关的信号通路和基因,并用于设计药物和其他治疗方法。通过生物计算,我们确定姜黄素可以影响这种疾病及其基因和信号通路。我们这项研究的目标是找到姜黄素通过哪些基因产生作用,并能维持皮质类固醇对抗氧化剂的功能。通过找到这些基因,就有可能准确找到姜黄素发挥作用的途径,从而设计出能引起这些途径的其他药物,并将其副作用降到最低。本研究考虑了健康样本(含/不含姜黄素)和无氧自由基样本(含/不含姜黄素)。最后,统计算法提取出有意义的基因作为有效的生物标记,以研究姜黄素对慢性阻塞性肺病的影响和信号通路。结果表明,最终获得的基因是文献证实的最关键基因,对慢性阻塞性肺病有效。最后,姜黄素被输入到 SwissTargetPrediction 中,以确定潜在的蛋白质受体。我们使用 LigPlot+ 软件将 iGEMDOCK 提供的受体-配体结合结果可视化。数据显示,每组中最重要的基因在其他研究中已被证实对该疾病有效,它们之间可以建立蛋白-蛋白相互作用网络,以研究它们的作用。

Apoptosis, also known as the programmed death of cells, is responsible for maintaining the homeostasis of tissues, and this function is carried out by caspases. The process of apoptosis is carried out via two distinct pathways: the extrinsic pathway, which is governed by death receptors, and the intrinsic pathway, also known as the mitochondrial pathway. The BCL-2 protein family encoded by the BCL-2 gene, located at the 18q21.33 chromosomal location, is in charge of regulating the intrinsic pathway, which is responsible for inducing cell death via the permeabilization of the mitochondrial membrane and the release of apoptosis-inducing components. The BCL-2 homology (BH1, BH2, BH3, BH4) domains of this family proteins are crucial for their functioning, and their common BH domains allow interactions between members of the same family and can also serve as indications of pro- or anti-apoptotic activity. A direct correlation may be shown between the overexpression of BCL-2 and the postponement of cell death. It has been determined that a change in the expression of BCL-2 is the root cause of a variety of malignancies, including lung, breast, melanoma, and chronic lymphocytic leukemia, multiple sclerosis, diabetes. In this review, we addressed the genetic information and structural homology of BCL-2 family members. Further, we elucidate the pro-apoptotic and anti-apoptotic roles of the family members. This review highlights the most recent developments in the BCL-2 protein family and presents evidence that targeting this family proteins may have a positive impact on the treatment of medical problems that are still underserved.
细胞凋亡也被称为细胞的程序性死亡,它负责维持组织的平衡,而这一功能是由 Caspases 实现的。细胞凋亡的过程通过两种不同的途径进行:由死亡受体支配的外在途径和内在途径,也称为线粒体途径。位于染色体 18q21.33 位置的 BCL-2 基因编码的 BCL-2 蛋白家族负责调节内在途径,该途径通过线粒体膜的通透性和凋亡诱导成分的释放诱导细胞死亡。该家族蛋白的 BCL-2同源(BH1、BH2、BH3、BH4)结构域对其功能起着至关重要的作用,其共同的BH结构域允许同一家族成员之间相互作用,也可作为促凋亡或抗凋亡活性的标志。BCL-2 的过度表达与细胞死亡的推迟之间可能存在直接的关联。目前已经确定,BCL-2 表达的变化是导致肺癌、乳腺癌、黑色素瘤、慢性淋巴细胞白血病、多发性硬化症、糖尿病等多种恶性肿瘤的根本原因。在这篇综述中,我们探讨了 BCL-2 家族成员的遗传信息和结构同源性。此外,我们还阐明了该家族成员的促凋亡和抗凋亡作用。这篇综述重点介绍了 BCL-2 蛋白家族的最新进展,并提出证据表明,以该家族蛋白为靶点可能会对治疗仍未得到充分治疗的医学问题产生积极影响。

Long non-coding RNAs, known as LncRNAs, have demonstrated a robust association with the pathogenesis of stroke. NRON and SNHG are among the most extensively studied lncRNAs in the context of atherosclerosis and inflammatory conditions. Given the absence of a current pathophysiological hypothesis regarding the potential relevance of the SNHG family and NRON lncRNAs in ischemic stroke (IS), this study aimed to investigate the altered expression of NRON and SNHG11 following atherosclerotic ischemic stroke (AIS) and their potential association with the risk of AIS. Blood samples were collected from 65 AIS patients (with large artery atherosclerosis or small vessel disease) and 65 controls. The expression levels of NRON and SNHG11 were assessed within the first 24 h following the stroke using quantitative real-time PCR. NRON expression exhibited a significant decrease in patients compared to controls, while no substantial difference was observed in the expression level of SNHG11 between the two groups. Furthermore, logistic regression analysis revealed a significant negative association between NRON expression and the risk of AIS (adjusted odds ratio = 0.70; 95% confidence interval 0.55–0.89, P = 0.004). These findings suggest that NRON may play a role in the pathogenesis of AIS and could potentially serve as a biomarker for the disease. To fully comprehend the mechanism underlying the association between NRON and AIS and to explore its potential therapeutic implications, further investigation is warranted.
被称为 LncRNA 的长非编码 RNA 与中风的发病机制有着密切的联系。NRON和SNHG是在动脉粥样硬化和炎症条件下研究最广泛的lncRNA之一。鉴于目前还没有关于 SNHG 家族和 NRON lncRNA 与缺血性中风(IS)潜在相关性的病理生理学假说,本研究旨在调查动脉粥样硬化性缺血性中风(AIS)后 NRON 和 SNHG11 表达的改变及其与 AIS 风险的潜在关联。本研究采集了65名AIS患者(大动脉粥样硬化或小血管疾病)和65名对照者的血样。采用定量实时 PCR 技术评估了中风后 24 小时内 NRON 和 SNHG11 的表达水平。与对照组相比,患者的 NRON 表达明显下降,而 SNHG11 的表达水平在两组之间没有发现明显差异。此外,逻辑回归分析显示,NRON表达与AIS风险之间存在显著的负相关(调整后的几率比=0.70;95%置信区间为0.55-0.89,P=0.004)。这些发现表明,NRON可能在AIS的发病机制中发挥作用,并有可能成为该疾病的生物标志物。为了充分理解NRON与AIS之间的关联机制,并探索其潜在的治疗意义,还需要进一步的研究。

These findings suggest that NRON may play a role in the pathogenesis of AIS and could potentially serve as a biomarker for the disease. To fully comprehend the mechanism underlying the association between NRON and AIS and to explore its potential therapeutic implications, further investigation is warranted.","PeriodicalId":39112,"journal":{"name":"Egyptian Journal of Medical Human Genetics","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139559827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

COVID-19 has its life-threatening complications more pronounced in people with underlying health conditions such as diabetes, cardiovascular disease and kidney disease. Inhibition of the sodiumglucose cotransporter 2 (SGLT2), which primarily increases urinary glucose excretion, is shown to be beneficial in patients with type 2 diabetes mellitus (T2D) and other comorbidities. SGLT2 is encoded by SLC5A2 gene, and of the several genetic variants, SNP rs9934336 is gaining importance for being associated with reduced HbA1c level and lower incidence of T2D. Since a complex bidirectional relationship exists between COVID-19 and hyperglycaemia, we conducted a worldwide association study to investigate the effect of rs9934336 on COVID-19 outcomes. Worldwide prevalence data of SLC5A2 SNP rs9934336 were obtained from relevant published articles and databases for genomic variants. COVID-19 data procured from the Worldometer website were used for conducting Spearman’s correlation analysis with minor allele frequency data of rs9934336. Significant positive correlation was observed between rs9934336 and COVID-19 incidence (p < 0.0001, r = 0.6225) as well as deaths (p < 0.0001, r = 0.5837). The present finding of significant association of SLC5A2 variant rs9934336 with COVID-19 risk has to be validated by case–control studies in diverse populations along with other variants regulating the expression and function of SGLT2.
COVID-19 在患有糖尿病、心血管疾病和肾脏疾病等基础疾病的人群中,其危及生命的并发症更为明显。钠-葡萄糖共转运体 2(SGLT2)主要增加尿糖排泄,抑制它对 2 型糖尿病(T2D)和其他合并症患者有益。SGLT2 由 SLC5A2 基因编码,在几种基因变异中,SNP rs9934336 因与 HbA1c 水平降低和 T2D 发病率降低相关而日益受到重视。由于 COVID-19 与高血糖之间存在复杂的双向关系,我们开展了一项全球关联研究,以调查 rs9934336 对 COVID-19 结果的影响。SLC5A2 SNP rs9934336 的全球流行率数据来自相关发表文章和基因组变异数据库。利用从 Worldometer 网站获取的 COVID-19 数据与 rs9934336 的小等位基因频率数据进行斯皮尔曼相关性分析。结果表明,rs9934336 与 COVID-19 发病率(p < 0.0001,r = 0.6225)和死亡率(p < 0.0001,r = 0.5837)之间存在显著的正相关。本研究发现 SLC5A2 变体 rs9934336 与 COVID-19 风险有明显关联,这一发现还需要在不同人群中进行病例对照研究,并与其他调节 SGLT2 表达和功能的变体一起进行验证。

Several reports discussed a connection between CD36 genotypes associated with obesity, influencing the development of Type 2 diabetes mellitus (T2DM). Therefore, this study examines the prognostic value of CD36 polymorphism rs1761667 (G/A) in individuals with obese T2DM. The investigation also explores the correlation between this genetic variation and the clinical/biochemical parameters of the subjects. Blood samples of a total of 475 subjects from north India were collected from the outpatient unit (OPD), Department of Medicine, KGMU, Lucknow as per inclusion/exclusion criteria. Anthropometric details of study subjects were recorded and biochemical parameters were estimated in 250 T2DM cases, 75 obese T2DM cases, and 150 controls. The CD36 gene variant rs1761667 (G/A) was subject to genotypic analysis using the polymerase chain reaction-restriction fragment length polymorphism (PCR–RFLP) method, utilizing specific primers and HhaI enzyme. All statistical analysis was done using SPSS (ver. 21.0) and Prism (5.01) software. Fasting plasma glucose (FPG), systolic blood pressure (SBP), post-prandial glucose (PPG) were significant in T2DM subjects. Lipid profile such as Total Cholesterol (TC), Low-Density Lipoprotein (LDL) and Very Low-Density Lipoprotein (VLDL) were also found significantly associated with obese T2DM cases. GA and AA genotypes of rs1761667 (G/A) showed significant associations in obese T2DM cases. The GA genotype demonstrated a considerable association (P < 0.001) with a 2.77-fold increased susceptibility to the high risk of T2DM. The AA genotype was found to be significantly associated (P = 0.008) with 2.94-fold higher risk of T2DM in obesity while 9.33 folds significant risk of developing obesity in T2DM cases. The risk of obesity in T2DM cases can be assessed by genotyping the CD36 genetic variant rs1761667 (G/A). However, raised FPG, PPG, TC, LDL, and VLDL showed poor prognosis in obese T2DM cases. CD36 gene variant can be proposed as a prognostic biomarker for risk prediction of T2DM and obesity, while anthro-biochemical risk factors as preventive biomarker.
一些报告讨论了与肥胖相关的 CD36 基因型与 2 型糖尿病(T2DM)发病之间的联系。因此,本研究探讨了 CD36 多态性 rs1761667 (G/A) 在肥胖 T2DM 患者中的预后价值。研究还探讨了该基因变异与受试者临床/生化指标之间的相关性。根据纳入/排除标准,研究人员从勒克瑙 KGMU 医学系门诊部(OPD)采集了印度北部共 475 名受试者的血样。对 250 例 T2DM 病例、75 例肥胖 T2DM 病例和 150 例对照者的人体测量细节进行了记录,并对生化指标进行了估计。采用聚合酶链式反应-限制性片段长度多态性(PCR-RFLP)方法,利用特定引物和 HhaI 酶对 CD36 基因变异体 rs1761667 (G/A) 进行了基因型分析。所有统计分析均使用 SPSS(21.0 版)和 Prism(5.01)软件进行。T2DM 受试者的空腹血糖(FPG)、收缩压(SBP)和餐后血糖(PPG)均有显著性差异。总胆固醇(TC)、低密度脂蛋白(LDL)和极低密度脂蛋白(VLDL)等血脂谱也被发现与肥胖 T2DM 病例显著相关。rs1761667(G/A)的 GA 和 AA 基因型在肥胖 T2DM 病例中显示出显著的相关性。GA 基因型与 T2DM 高风险易感性增加 2.77 倍有相当大的关联(P < 0.001)。研究发现,AA 基因型与肥胖 T2DM 风险增加 2.94 倍显著相关(P = 0.008),而 T2DM 病例发生肥胖的风险增加 9.33 倍。通过对 CD36 基因变异体 rs1761667(G/A)进行基因分型,可以评估 T2DM 病例的肥胖风险。然而,FPG、PPG、TC、LDL 和 VLDL 的升高表明肥胖 T2DM 病例的预后较差。CD36基因变异可作为预测T2DM和肥胖症风险的预后生物标志物,而人类生化风险因素可作为预防生物标志物。

Ehlers–Danlos syndrome (EDS), osteogenesis imperfecta (OI), and cutis laxa (CL) are three rare and heterogeneous connective tissue disorders. Patients with these syndromes have similar manifestations and unpredictable prognosis, making a misdiagnosis highly probable. Some of their subtypes are inherited in autosomal recessive patterns, so they are expected to be prevalent in populations like Iran, where consanguineous marriages are common. In the current work, a cohort of Iranian patients with overlapping phenotypes of the EDS/OI/CL and their mutation spectrum was defined. Based on this, in silico analysis was conducted to anticipate further probable genetic variations. Pathogenicity of EDS, OI, and CL variants in Iranian patients was evaluated using Web servers. A protein interaction network was created by String database and visualized using a Python-based library. The Iranome database was used to predict other genetic mutations in all reported genes of EDS, OI, and CL syndromes. In the EDS/OI/CL overlap phenotype, 32 variants in 18 genes have been involved. At least 59% of patients were from families with consanguineous marriages. Interaction analysis showed that COL1A1, COL1A2, CRTAP, LEPRE1, PLOD1, and ADAMTS2 have the most significant impact within the protein network of EDS/OI/CL overlap phenotype. Analyzing the Iranome database revealed 46 variants of EDS, OI, and CL genes potentially disease causing. The overlapping phenotype of EDS, OI, and CL syndromes requires genetic testing (e.g., whole-exome sequencing) to reveal respective variants, which helps to diagnose more accurately and manage the disease more effectively. Particularly in populations with high rates of consanguineous marriages, such as Iran, genetic screening plays a crucial role in premarital and prenatal counseling to prevent the transmission of these rare connective tissue disorders.
埃勒斯-丹洛斯综合征(EDS)、成骨不全症(OI)和皮肤松弛症(CL)是三种罕见的异质性结缔组织疾病。这些综合征的患者具有相似的表现和难以预测的预后,因此极有可能被误诊。它们中的一些亚型是常染色体隐性遗传,因此在伊朗等近亲结婚现象普遍的国家很常见。在目前的研究工作中,确定了具有 EDS/OI/CL 表型重叠及其突变谱的伊朗患者队列。在此基础上,进行了硅分析,以预测更多可能的基因变异。利用网络服务器评估了伊朗患者中 EDS、OI 和 CL 变异的致病性。通过 String 数据库创建了蛋白质相互作用网络,并使用基于 Python 的库将其可视化。伊朗基因组数据库用于预测 EDS、OI 和 CL 综合征所有报告基因中的其他基因突变。在 EDS/OI/CL 重叠表型中,涉及 18 个基因中的 32 个变异。至少59%的患者来自近亲结婚家庭。相互作用分析表明,COL1A1、COL1A2、CRTAP、LEPRE1、PLOD1和ADAMTS2在EDS/OI/CL重叠表型的蛋白质网络中影响最大。通过分析 Iranome 数据库,发现了 46 个可能致病的 EDS、OI 和 CL 基因变异。EDS、OI和CL综合征的重叠表型需要通过基因检测(如全外显子组测序)来揭示各自的变异,这有助于更准确地诊断和更有效地管理疾病。特别是在伊朗等近亲结婚率较高的人群中,基因筛查在婚前和产前咨询中发挥着至关重要的作用,以防止这些罕见结缔组织疾病的传播。

Biallelic variants in SPARC are extremely rare, and have been reported in only a few cases of autosomal recessive osteogenesis imperfecta (OI) type XVII. Here, we describe an individual with a SPARC homozygous missense variant (c.787G > A; p.Glu263Lys) and expand on the phenotype. The proband had a history of multiple fractures, osteopenia, severe thoracolumbar levoscoliosis, rib fusion, global hypotonia, conductive hearing loss, and was non-ambulatory. Several of his features were similar to previously described cases, such as early neuromuscular concerns, scoliosis, long bone and vertebral compression fractures, and delayed motor milestones, suggesting these are consistent across SPARC-related osteogenesis imperfecta (OI). However, the proband sustained fractures at a younger age with a more severe course compared to most previous reports. He also had bony fusion of several ribs and hearing loss, which have not been reported in SPARC-related OI. Overall, the proband supports the current phenotype of SPARC-related OI, but also expands the phenotypic variability.
SPARC 的双唇变异极为罕见,仅在少数常染色体隐性成骨不全症(OI)XVII 型病例中有报道。在这里,我们描述了一个患有 SPARC 同源错义变异(c.787G > A; p.Glu263Lys)的个体,并对其表型进行了进一步的研究。该患者曾多次骨折、骨质疏松、严重的胸腰椎左侧骨质疏松症、肋骨融合、全身肌张力低下、传导性听力损失,并且不能行走。他的一些特征与之前描述的病例相似,如早期神经肌肉问题、脊柱侧弯、长骨和脊椎压缩性骨折以及运动发育迟缓,这表明这些特征在与SPARC相关的成骨不全症(OI)中是一致的。不过,与之前的大多数报告相比,该患者骨折的年龄更小,骨折的过程也更严重。他的几根肋骨也发生了骨融合,并伴有听力损失,而这些在SPARC相关成骨不全症中尚未见报道。总之,该病例支持SPARC相关OI的现有表型,但也扩大了表型的变异性。

Association of p53 codon 72 polymorphism with weight and metabolic diseases in a Central Indian population 印度中部人群中 p53 密码子 72 多态性与体重和代谢疾病的关系

Metabolic dysregulation leading to diabetes is a major public health concern in India. While evidence has pointed to a role for genetic factors, there is still limited knowledge regarding the specific variants that play a part in this process. Recent studies have implicated Tumor protein, p53, a well-known tumor suppressor, in maintaining metabolic homeostasis in our body. Polymorphisms that can disrupt this function are thought to increase susceptibility to diabetic and prediabetic phenotypes like Metabolic syndrome (MetS). A common polymorphism at codon 72 (rs1042522) is associated with obesity and other metabolic disorders. However, its role may vary depending on the specific population and disease context. Our study aimed to evaluate whether the polymorphism at codon 72 of p53 (rs1042522) is associated with MetS and Diabetes, in a Central Indian population. A total of 66 individuals and 63 healthy controls, identified based on the National Cholesterol Education Program (NCEP)/Adult Treatment Panel-III (ATP-III) 2001 guidelines, were enrolled in the study. The carriers expressing mutant allele “G” for arginine at codon 72 had higher weight than those having wild-type allele “C” which codes for proline (p = 0.038). The majority of the subjects were heterozygous for p53 codon 72 polymorphism though the association was not statistically significant for either MetS or diabetes. Our findings suggest that p53 codon 72 (rs1042522) varaints may trigger metabolic dysfunction by impacting weight. The polymorphism appears to confer a heterozygous advantage, as individuals with a heterozygous genotype exhibited the highest susceptibility to metabolic disease. Although further studies are required, our results for the first time indicate that the p53 codon 72 (rs1042522) polymorphism could be considered a genetic marker to predict the increased susceptibility to diabetic and prediabetic phenotypes among Central Indian population.
导致糖尿病的代谢失调是印度的一个主要公共卫生问题。虽然有证据表明遗传因素在其中发挥了作用,但人们对在这一过程中发挥作用的特定变异体的了解仍然有限。最近的研究表明,肿瘤蛋白 p53(一种著名的肿瘤抑制因子)与维持体内代谢平衡有关。能破坏这一功能的多态性被认为会增加对糖尿病和糖尿病前期表型(如代谢综合征)的易感性。第 72 个密码子上的常见多态性(rs1042522)与肥胖和其他代谢紊乱有关。然而,其作用可能因特定人群和疾病背景而异。我们的研究旨在评估印度中部人群中 p53 第 72 个密码子上的多态性(rs1042522)是否与 MetS 和糖尿病有关。根据美国国家胆固醇教育计划(NCEP)/成人治疗小组-III(ATP-III)2001 年指南,共有 66 名个体和 63 名健康对照参加了研究。在第 72 个密码子上表达精氨酸突变等位基因 "G "的携带者的体重高于编码脯氨酸的野生型等位基因 "C "的携带者(P = 0.038)。大多数受试者是 p53 第 72 号密码子多态性的杂合子,但与 MetS 或糖尿病的相关性在统计学上并不显著。我们的研究结果表明,p53 第 72 个密码子(rs1042522)变异可能会通过影响体重引发代谢功能障碍。该多态性似乎具有杂合子优势,因为杂合子基因型的个体对代谢性疾病的易感性最高。虽然还需要进一步研究,但我们的研究结果首次表明,p53 第 72 个密码子(rs1042522)多态性可被视为一种遗传标记,用于预测中印度人群对糖尿病和糖尿病前期表型的易感性。

A total of 66 individuals and 63 healthy controls, identified based on the National Cholesterol Education Program (NCEP)/Adult Treatment Panel-III (ATP-III) 2001 guidelines, were enrolled in the study. The carriers expressing mutant allele “G” for arginine at codon 72 had higher weight than those having wild-type allele “C” which codes for proline (p = 0.038). The majority of the subjects were heterozygous for p53 codon 72 polymorphism though the association was not statistically significant for either MetS or diabetes. Our findings suggest that p53 codon 72 (rs1042522) varaints may trigger metabolic dysfunction by impacting weight. The polymorphism appears to confer a heterozygous advantage, as individuals with a heterozygous genotype exhibited the highest susceptibility to metabolic disease. Although further studies are required, our results for the first time indicate that the p53 codon 72 (rs1042522) polymorphism could be considered a genetic marker to predict the increased susceptibility to diabetic and prediabetic phenotypes among Central Indian population.","PeriodicalId":39112,"journal":{"name":"Egyptian Journal of Medical Human Genetics","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139471132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
