  • 文章类型: Journal Article
    为了解南疆扭曲红斑马对苯并咪唑(BZ)的抗性,三个单核苷酸多态性(SNPs)命名为F167Y,E198A,F200Y,在与BZ抗性相关的同种型1β-微管蛋白基因中,对南疆和静县和民丰县的绵羊变形猪种群进行了调查。简而言之,在新疆南部两个地区的城市屠宰场中,从70只被宰杀的绵羊中,有52只绵羊中收集了190只。使用靶向ITS-2的H.contortus特异性引物通过ITS-2的PCR扩增来确认每个成虫的物种身份。然后通过同种型-1β-微管蛋白基因的PCR测序研究样品在基因座167、198和200处的BZ相关SNP。结果表明,在所研究的H.contortus种群中仅检测到E198A和F200Y突变。E198A突变(纯合和杂合子抗性:在来自民丰县和和静县的40%和30%的测序样品中发现,分别)与F200Y突变(纯合和杂合子抗性:在来自民丰县和和静县的14%和13.3%的测序样品中发现,分别)。结果表明,南疆某些地区的扭曲口蹄疫种群中BZ抗性很高。我们的发现为在类似条件的地区预防和控制变形病提供了有价值的信息。
    To understand the benzimidazole (BZ) resistance of Haemonchus contortus in Southern Xinjiang, three single nucleotide polymorphisms (SNPs) designated as F167Y, E198A, and F200Y, in the isotype-1 β-tubulin gene which are associated with BZ resistance, were investigated for H. contortus populations from sheep in Hejing and Minfeng counties of Southern Xinjiang. In brief, a total of 190 H. contortus adults were collected from 52 out of 70 slaughtered sheep in city abattoirs across two regions in Southern Xinjiang. The species identity of each adult worm was confirmed by PCR amplification of ITS-2 using H. contortus-specific primers targeting the ITS-2. The samples were then investigated for BZ-related SNPs at locus 167, 198, and 200, by PCR-sequencing of the isotype-1 β-tubulin gene. The results showed that only E198A and F200Y mutations were detected in the investigated H. contortus populations. The E198A mutation (homozygous and heterozygote resistant: found in 40% and 30% of sequenced samples from Minfeng and Hejing counties, respectively) was predominant compared with the F200Y mutation (homozygous and heterozygote resistant: found in 14% and 13.3% of sequenced samples from Minfeng and Hejing counties, respectively). The results indicate a high prevalence of BZ resistance in H. contortus populations from certain areas of Southern Xinjiang. Our findings provide valuable information for the prevention and control of H. contortus in areas with similar conditions.

    结直肠癌(CRC)是最常见和引起死亡的肿瘤之一,种群之间有不同的分布。强烈的遗传性倾向是一小部分CRC的原因,大多数病例没有透明的遗传背景。这是探索癌症低易感性遗传变异的广阔舞台。尽管如此,迄今为止进行的研究未能得出一致的结论,并且经常具有相互冲突的信息,在这个领域造成混乱。因此,我们决定组织关于这个主题的现有知识。我们筛选了PubMed和GoogleScholar数据库。我们通过标记收集的基因位点绘制标记:致癌基因,肿瘤抑制基因,参与DNA损伤修复的基因,参与代谢途径的基因,参与甲基化的基因,改变结肠微环境的基因,和参与免疫反应的基因。增加癌症风险的低渗透遗传变异通常是人群特异性的,因此迫切需要大规模测试。只有金融决策者与社会教育者团结在一起,这种努力才能成功。医学专家,遗传顾问,和科学界。各国的政策应优先考虑这一主题的研究,而不计成本,因为这是最好的投资。在这次审查中,我们列出了潜在的低外显率CRC易感性等位基因,其作用尚待确定.
    Colorectal cancer (CRC) is one of the most frequent and mortality-causing neoplasia, with various distributions between populations. Strong hereditary predispositions are the causatives of a small percentage of CRC, and most cases have no transparent genetic background. This is a vast arena for exploring cancer low-susceptibility genetic variants. Nonetheless, the research that has been conducted to date has failed to deliver consistent conclusions and often features conflicting messages, causing chaos in this field. Therefore, we decided to organize the existing knowledge on this topic. We screened the PubMed and Google Scholar databases. We drew up markers by gene locus gathered by hallmark: oncogenes, tumor suppressor genes, genes involved in DNA damage repair, genes involved in metabolic pathways, genes involved in methylation, genes that modify the colonic microenvironment, and genes involved in the immune response. Low-penetration genetic variants increasing the risk of cancer are often population-specific, hence the urgent need for large-scale testing. Such endeavors can be successful only when financial decision-makers are united with social educators, medical specialists, genetic consultants, and the scientific community. Countries\' policies should prioritize research on this subject regardless of cost because it is the best investment. In this review, we listed potential low-penetrance CRC susceptibility alleles whose role remains to be established.

    背景:近年来,专业运动员补充肌酸的研究引起了极大的兴趣。然而,对补充的反应所涉及的遗传学是未知的。这项研究的目的是分析,第一次,补充肌酸后,职业足球运动员的肌肉性能相关基因与体重指数(BMI)和肌肉质量增加以及脂肪质量减少的风险之间的关系。
    方法:对于这项纵向研究,招募了一百六十一名男子职业足球运动员。多态性ACEI/D,ACTN3c.1729C>T,AMPD1c.34C>T,CKMc.*800A>G,使用单核苷酸引物延伸(SNPE)对MLCK(c.49C>T和c.3785C>A)进行基因分型。为了评估这六个多态性的综合影响,计算总基因型评分(TGS).肌酸补充方案由20g/天的肌酸一水合物持续5天(负荷剂量)和3-5g/天持续7周(维持剂量)组成。人体测量特征(体重指数(BMI),脂肪,和肌肉质量)在肌酸补充方案之前和之后记录。2022/2023赛季非接触式肌肉损伤的特征根据损伤记录的共识声明进行分类。结果表明,在肌肉质量增加方面,应答者和非应答者之间ACE和AMPD1的等位基因频率不同(均p<0.05)。TGS超过54.16a.u.的玩家肌肉质量增加的比值比(OR)为2.985(95CI:1.560-5.711;p=0.001)。相比之下,TGS低于54.16a.u.的人在本赛季遭受非接触式肌肉损伤,OR为9.385(95CI:4.535-19.425;p<0.001)。
    结论:职业足球运动员补充肌酸后,BMI和肌肉质量的增加受到与肌肉表现相关的有利基因型组合产生的TGS的影响。在这组职业足球运动员中,在补充肌酸的情况下,AMPD1的CC基因型和C等位基因与肌肉质量增加的可能性更高有关。
    BACKGROUND: In recent years, the study of creatine supplementation in professional athletes has been of great interest. However, the genetics involved in response to supplementation is unknown. The aim of this study was to analyse, for the first time, the relationship between muscle performance-related genes and the risk of an increased body mass index (BMI) and muscle mass and a decrease in fat mass in professional football players after creatine supplementation.
    METHODS: For this longitudinal study, one hundred and sixty-one men\'s professional football players were recruited. The polymorphisms ACE I/D, ACTN3 c.1729C>T, AMPD1 c.34C>T, CKM c.*800A>G, and MLCK (c.49C>T and c.37885C>A) were genotyped using Single-Nucleotide Primer Extension (SNPE). To assess the combined impact of these six polymorphisms, a total genotype score (TGS) was calculated. The creatine supplementation protocol consisted of 20 g/day of creatine monohydrate for 5 days (loading dose) and 3-5 g/day for 7 weeks (maintenance dose). Anthropometric characteristics (body mass index (BMI), fat, and muscle mass) were recorded before and after the creatine supplementation protocol. Characteristics of non-contact muscle injuries during the 2022/2023 season were classified according to a consensus statement for injury recording. The results showed that the allelic frequencies of ACE and AMPD1 differed between responders and non-responders in muscle mass increase (all p < 0.05). Players with a TGS exceeding 54.16 a.u. had an odds ratio (OR) of 2.985 (95%CI: 1.560-5.711; p = 0.001) for muscle mass increase. By contrast, those with a TGS below 54.16 a.u. had an OR of 9.385 (95%CI: 4.535-19.425; p < 0.001) for suffering non-contact muscle injuries during the season.
    CONCLUSIONS: The increase in BMI and muscle mass in response to creatine supplementation in professional football players was influenced by a TGS derived from the combination of favourable genotypes linked to muscle performance. The CC genotype and C allele of AMPD1 were particularly associated with a higher likelihood of muscle mass increase under creatine supplementation in this group of professional football players.

    背景:发育性髋关节发育不良(DDH)是儿童残疾的常见原因,DDH的发病率表现出显著的家族聚集性。由于DDH的遗传因素仍然未知,在中国西南地区的汉族人群中评估了五个候选单核苷酸多态性(SNP)与DDH的相关性。
    方法:对276例DDH患者和318例健康对照进行了病例对照关联研究。通过SNPshot和多重PCR进行病例组和对照组的SNP基因分型。通过多重PCR对病例组和对照组的SNP进行基因分型。使用χ2检验评估DDH与候选SNP之间的关系。
    结果:HIBCH中rs291412和FTCDNL1中rs769956的基因型分布在病例组和对照组之间差异有统计学意义(P<0.05)。经过遗传模型分析,Logistic回归分析显示,rs291412的C等位基因对DDH具有保护作用(OR=0.605,P=0.010),rs769956的G等位基因是危险因素(OR=2.939,P=0.010)。S.
    结论:这些SNP可能与DDH易感性相关,但更大规模的基于人群的研究应该证实目前的结果。
    BACKGROUND: Developmental dysplasia of the hip (DDH) is a common cause of childhood disability, and the incidence of DDH shows significant familial aggregation. As the genetic factors of DDH remain unknown, the correlation between five candidate single nucleotide polymorphisms (SNPs) and DDH was evaluated in the Han Chinese population of Southwest China.
    METHODS: A case‒control association study was conducted in 276 patients with DDH and 318 healthy controls. SNP genotyping in the case and control groups was performed by SNPshot and multiple PCR. SNPs were genotyped in the case and control groups by multiplex PCR. The relationship between DDH and candidate SNPs was evaluated using the χ2 test.
    RESULTS: The genotype distributions of rs291412 in HIBCH and rs769956 in FTCDNL1 were different between the case and control groups (P < 0.05). After genetic model analysis, logistic regression analysis revealed that the C allele of rs291412 had a protective effect on DDH (OR = 0.605, P = 0.010) and that the G allele of rs769956 was a risk factor (OR = 2.939, P = 0.010).s.
    CONCLUSIONS: These SNPs could be associated with susceptibility to DDH but larger population-based studies should confirm the current results.

    药物超敏反应是由免疫应答引起的常见反应。它们至关重要,因为它们可能会产生严重和致命的结果。某些药物可能会导致药物不良反应(ADR)。如药物超敏反应(DHRs),这可能是由于完整药物或其代谢物与人白细胞抗原(HLAs)和T细胞受体(TCR)的相互作用而发生的。这种类型在暴露后24-72小时内发展,被归类为DHRs的IV型。急性全身性外因性脓疱病(AGEP),Stevens-Johnson综合征(SJS)/中毒性表皮坏死松解症(TEN)和具有嗜酸性粒细胞增多和全身症状的药物反应(DRESS)是严重皮肤不良反应(SCAR)的类型。在这次审查中,我们的目标是讨论ADR的类型,参与其发展的机制,以及免疫遗传因素的作用,例如IV型DHR中的HLA,单核苷酸多态性(SNPs),和一些表观遗传修饰,例如,多种基因及其启动子中的DNA/组蛋白甲基化可能使受试者易患DHRs。总之,开发有希望的新型体外或体内诊断和预后标志物对于识别易感受试者或提供治疗方案以将药物过敏患者作为个性化药物至关重要。
    Drug hypersensitivities are common reactions due to immunologic responses. They are of utmost importance because they may generate severe and fatal outcomes. Some drugs may cause Adverse Drug Reactions (ADRs), such as drug hypersensitivity reactions (DHRs), which can occur due to the interaction of intact drugs or their metabolites with Human Leukocyte Antigens (HLAs) and T cell receptors (TCRs). This type develops over a period of 24-72 h after exposure and is classified as type IV of DHRs. Acute generalized exanthematic pustulosis (AGEP), Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) and drug reaction with eosinophilia and systemic symptoms (DRESS) are types of Severe Cutaneous Adverse Reactions (SCARs). In this review, we aim to discuss the types of ADRs, the mechanisms involved in their development, and the role of immunogenetic factors, such as HLAs in type IV DHRs, single-nucleotide polymorphisms (SNPs), and some epigenetic modifications, e.g., DNA/histone methylation in a variety of genes and their promoters which may predispose subjects to DHRs. In conclusion, development of promising novel in vitro or in vivo diagnostic and prognostic markers is essential for identifying susceptible subjects or providing treatment protocols to work up patients with drug allergies as personalized medicine.

    幻牙痛(PTP)是一种非牙源性神经性牙痛,在适当的牙髓切除术或拔牙后很少发生。PTP的原因未知。我们调查了与PTP相关的疼痛相关遗传因素。四种疼痛相关基因,包括G蛋白偶联受体158(GPR158)和含磷酸核糖转移酶结构域1(PRTFDC1),在人类基因组上彼此相邻。这四个基因中的一些或它们的基因组区域可能与PTP有关。我们统计分析了基因组区域中的单核苷酸多态性(SNP)与PTP患者(PTP组)的PTP之间的关联,其他口面部疼痛(OFP组),和健康的对照受试者。然后,我们对表达数量性状基因座(eQTL)进行了数据库搜索。对于即使在Bonferroni校正后也与PTP显着相关的七个SNP,我们关注rs12411980标签SNP(P=9.42×10-4)。对PTP组和健康受试者组(组标签:NOC和TD)的统计分析表明,rs12411980SNP的GG基因型在PTP组中的比率显着高于健康受试者组(PTP组vs.NOC组:P=2.92×10-4,PTP组vs.TD组:P=5.46×10-4;PTP组GG百分比:30%,NOC组12%,TD组的11%)。这些结果表明rs12411980SNP的GG基因型更容易受到PTP的影响。与rs12411980SNP处于强连锁不平衡的rs2765697SNP是与rs2765697SNP的健康受试者组中的次要等位基因纯合子中的较高PRTFDC1表达相关的eQTL。因此,在rs12411980SNP的健康受试者组中,次要等位基因纯合子(GG基因型)的PRTFDC1表达类似地增加,这将导致对PTP的更大敏感性。
    Phantom tooth pain (PTP) is one type of non-odontogenic neuropathic toothache, which rarely occurs after appropriate pulpectomy or tooth extraction. The cause of PTP is unknown. We investigated pain-related genetic factors that are associated with PTP. Four pain-associated genes, including G protein-coupled receptor 158 (GPR158) and phosphoribosyl transferase domain containing 1 (PRTFDC1), are adjacent to each other on the human genome. Some of these four genes or their genomic region may be related to PTP. We statistically analyzed associations between single-nucleotide polymorphisms (SNPs) in the genomic region and PTP in patients with PTP (PTP group), other orofacial pain (OFP group), and healthy control subjects. We then performed a database search of expression quantitative trait loci (eQTLs). For the seven SNPs that were significantly associated with PTP even after Bonferroni correction, we focused on the rs12411980 tag SNP (P = 9.42 × 10-4). Statistical analyses of the PTP group and healthy subject groups (group labels: NOC and TD) revealed that the rate of the GG genotype of the rs12411980 SNP was significantly higher in the PTP group than in the healthy subject groups (PTP group vs. NOC group: P = 2.92 × 10-4, PTP group vs. TD group: P = 5.46 × 10-4; percentage of GG: 30% in PTP group, 12% in NOC group, 11% in TD group). These results suggest that the GG genotype of the rs12411980 SNP is more susceptible to PTP. The rs2765697 SNP that is in strong linkage disequilibrium with the rs12411980 SNP is an eQTL that is associated with higher PRTFDC1 expression in the minor allele homozygotes in the healthy subject groups of the rs2765697 SNP. Thus, PRTFDC1 expression similarly increases in the minor allele homozygotes (GG genotype) in the healthy subject groups of the rs12411980 SNP, which would lead to greater susceptibility to PTP.

    背景:已知遗传多态性在骨质疏松症的发展中起着至关重要的作用。维生素D3通过维生素D受体(VDR)调节骨稳态。VDR活性降低会增加骨质疏松症的风险。研究设计:病例对照研究。
    方法:这项病例对照研究调查了VDR基因中六个单核苷酸多态性(SNP)之间的潜在关联(rs11568820,rs4516035,rs2228570,rs1544410,rs7975232和rs731236)与克尔曼省骨质疏松症的发生。使用聚合酶链反应-限制性片段长度多态性分析SNP的基因型,四引物扩增难治性突变系统-PCR,并对两组骨质疏松症患者(n=40)和对照组(n=42)进行测序。此外,测量患者血清中钙和维生素D3的水平,并使用I-TASSER进行VDR结构和相互作用的计算机模拟分析,ProSA,PROCHECK,遗传狂躁症,GTEx,GPS6.0
    结果:没有患者出现钙或维生素D3缺乏。在六个SNP中,只有rs4516035中的T等位基因,它导致一个称为VDRA的较短变体,与骨质疏松易感性显著相关(比值比=3.061,P=0.007)。计算机模拟分析表明,3D结构,表达式,VDRA的转录后修饰与更延伸的变体不同,VDRB1.VDRB1在暴露于阳光下的皮肤中上调,它与合作伙伴的互动不同于VDRA。
    结论:尽管维生素D水平充足,VDRA变体,活性较低,可能会增加被研究人群骨质疏松症的易感性。这些发现阐明了基因筛查对个性化医疗的重要性以及预防和治疗策略的有效性。
    BACKGROUND: Genetic polymorphisms are known to play a crucial role in the development of osteoporosis. Vitamin D3 regulates bone homeostasis through the vitamin D receptor (VDR). Reduced VDR activity increases osteoporosis risk. Study Design: A case-control study.
    METHODS: This case-control study investigated the potential association between six single-nucleotide polymorphisms (SNPs) within the VDR gene (rs11568820, rs4516035, rs2228570, rs1544410, rs7975232, and rs731236) and the occurrence of osteoporosis in Kerman province. The genotypes of the SNPs were analyzed using polymerase chain reaction-restriction fragment length polymorphism, tetra primer amplification refractory mutation system-PCR, and sequencing in two groups of osteoporosis patients (n=40) and controls (n=42). Additionally, the levels of calcium and vitamin D3 in the serum of the patients were measured, and the in silico analysis of the VDR structure and interaction was performed using I-TASSER, ProSA, PROCHECK, GeneMANIA, GTEx, and GPS 6.0.
    RESULTS: None of the patients exhibited calcium or vitamin D3 deficiencies. Among the six SNPs, only the T allele in rs4516035, which leads to a shorter variant called VDRA, showed a significant association with susceptibility to osteoporosis (odds ratio=3.061, P=0.007). The in silico analysis demonstrated that the 3D structure, expression, and post-transcriptional modification of VDRA are distinct from those of the more extended variant, VDRB1. VDRB1 is upregulated in sun-exposed skin, and its interactions with its partners differ from those of VDRA.
    CONCLUSIONS: Despite adequate vitamin D levels, the VDRA variant, which has lower activity, could increase the predisposition to osteoporosis in the studied population. These findings clarify the importance of genetic screening for personalized medicine and the effectiveness of prevention and treatment strategies.

    流感病毒具有单链的RNA基因组,负感,和分段配置。流感病毒引起急性呼吸道疾病,在人类中通常被称为“流感”。在某些个体中,流感可导致肺炎和急性呼吸窘迫综合征。甲型流感病毒(IAV)是最重要的,因为它引起反复的季节性流行,偶尔的大流行,以及人群中的人畜共患疫情,全球。宿主对IAV感染的先天性免疫反应在感知中起着至关重要的作用,预防,清除感染以及流感疾病病理。宿主细胞通过多种受体和机制感知IAV感染,最终诱导出一致的先天抗病毒反应和抗病毒状态的产生,抑制和清除宿主细胞的感染。然而,IAV通过不同的机制拮抗和逃避先天抗病毒反应的许多步骤。在这里,我们回顾了这些宿主和病毒机制。这篇综述涵盖了宿主先天免疫反应的大多数方面,即,(1)对传入的病毒颗粒的感知,(2)下游先天抗病毒信号通路的激活,(3)干扰素刺激基因的表达,(4)和病毒的拮抗和逃逸。
    Influenza virus possesses an RNA genome of single-stranded, negative-sensed, and segmented configuration. Influenza virus causes an acute respiratory disease, commonly known as the \"flu\" in humans. In some individuals, flu can lead to pneumonia and acute respiratory distress syndrome. Influenza A virus (IAV) is the most significant because it causes recurring seasonal epidemics, occasional pandemics, and zoonotic outbreaks in human populations, globally. The host innate immune response to IAV infection plays a critical role in sensing, preventing, and clearing the infection as well as in flu disease pathology. Host cells sense IAV infection through multiple receptors and mechanisms, which culminate in the induction of a concerted innate antiviral response and the creation of an antiviral state, which inhibits and clears the infection from host cells. However, IAV antagonizes and escapes many steps of the innate antiviral response by different mechanisms. Herein, we review those host and viral mechanisms. This review covers most aspects of the host innate immune response, i.e., (1) the sensing of incoming virus particles, (2) the activation of downstream innate antiviral signaling pathways, (3) the expression of interferon-stimulated genes, (4) and viral antagonism and escape.

    虽然母猪不直接进入市场,它们在猪场的仔猪饲养中起着重要的作用。他们消耗大量的饲料,造成了巨大的环境负担。养猪场可以通过增加猪的产仔数(LS)来增加收入并减少环境污染。PCR-RFLP/SSCP和GWAS是评估候选基因单核苷酸多态性(SNP)的常用方法。我们对SNP对猪LS的影响进行了系统的荟萃分析。我们使用传统和网络荟萃分析收集和分析了过去30年发表的数据。试验序贯分析(TSA)用于分析人口数据。使用基因集富集分析和蛋白质-蛋白质相互作用网络分析来分析GWAS数据集。结果表明,候选基因与LS呈正相关,PCR-RFLP/SSCP的缺陷影响了候选基因结果的可靠性。然而,具有高和低LSs的基因型没有显着优势。当前母猪的育种和管理实践应考虑增加LS,同时减少泌乳长度并尽可能减少母猪的非怀孕期。
    Although sows do not directly enter the market, they play an important role in piglet breeding on farms. They consume large amounts of feed, resulting in a significant environmental burden. Pig farms can increase their income and reduce environmental pollution by increasing the litter size (LS) of swine. PCR-RFLP/SSCP and GWAS are common methods to evaluate single-nucleotide polymorphisms (SNPs) in candidate genes. We conducted a systematic meta-analysis of the effect of SNPs on pig LS. We collected and analysed data published over the past 30 years using traditional and network meta-analyses. Trial sequential analysis (TSA) was used to analyse population data. Gene set enrichment analysis and protein-protein interaction network analysis were used to analyse the GWAS dataset. The results showed that the candidate genes were positively correlated with LS, and defects in PCR-RFLP/SSCP affected the reliability of candidate gene results. However, the genotypes with high and low LSs did not have a significant advantage. Current breeding and management practices for sows should consider increasing the LS while reducing lactation length and minimizing the sows\' non-pregnancy period as much as possible.

    目的:我们试图研究细胞周期蛋白依赖性激酶抑制剂2B反义RNA1(CDKN2B-AS1)基因多态性对糖尿病视网膜病变(DR)易感性的影响。
    方法:CDKN2B-AS1基因的五个单核苷酸多态性(SNP),在280例DR和455例无DR糖尿病对照中检查了rs564398,rs1333048,rs1537373,rs2151280和rs8181047。
    结果:在这些测试的基因座中,我们证明了至少一个rs2151280多态性等位基因(G)的糖尿病携带者(AG和GG;AOR,1.613;95%CI,1.040-2.501;p=0.033)对增殖性DR更敏感,但对非增殖性DR不敏感。在rs2151280的多态性等位基因(G)的纯合子中,这种与发生增殖性DR的风险的遗传关联得到了进一步加强(GG;AOR,2.194;95%CI,1.117-4.308;p=0.023)。我们检测到rs2151280的多态性等位基因(G)与增殖性DR患者(OR,1.503;95%CI,1.112-2.033;p=0.008),但与整个DR或非增殖性DR组无关。此外,与不具有rs2151280(AA)多态性等位基因的人相比,携带至少一个rs2151280(AG+GG)多态性等位基因的DR患者表现出较低的肾小球滤过率和HDL胆固醇水平,揭示rs2151280在糖尿病的肾脏和心血管并发症中的促进作用。
    结论:综合来看,我们的发现提示CDKN2B-AS1基因多态性对DR进展的影响。
    OBJECTIVE: We attempted to test the influences of cyclin dependent kinase inhibitor 2B antisense RNA 1 (CDKN2B-AS1) gene polymorphisms on the susceptibility to Diabetic retinopathy (DR).
    METHODS: Five single-nucleotide polymorphisms (SNPs) of the CDKN2B-AS1 gene, rs564398, rs1333048, rs1537373, rs2151280, and rs8181047 were examined in 280 DR cases and 455 DR-free diabetic controls.
    RESULTS: Among these loci tested, we demonstrated that diabetic carriers of at least one polymorphic allele (G) of rs2151280 (AG and GG; AOR, 1.613; 95% CI, 1.040-2.501; p = 0.033) are more susceptible to proliferative DR but not non-proliferative DR. This genetic association with the risk of developing proliferative DR was further strengthened in homozygotes for the polymorphic allele (G) of rs2151280 (GG; AOR, 2.194; 95% CI, 1.117-4.308; p = 0.023). We detected a significant association of the polymorphic allele (G) of rs2151280 with proliferative DR patients (OR, 1.503; 95% CI, 1.112-2.033; p = 0.008) but not with the entire DR or non-proliferative DR group. Moreover, as compared to those who do not possess the polymorphic allele of rs2151280 (AA), DR patients carrying at least one polymorphic allele of rs2151280 (AG + GG) exhibited a lower glomerular filtration rate and HDL cholesterol level, revealing a promotive role of rs2151280 in renal and cardiovascular complications of diabetes.
    CONCLUSIONS: Taken together, our findings implicate an impact of CDKN2B-AS1 gene polymorphisms on the progression of DR.
