Background: The chronic exposure to air pollution-derived fine particulate matter (PM2.5) is suspected of exacerbating and even causing chronic inflammatory lung diseases. However, the knowledge of the underlying mechanisms is still incomplete. Objectives: To assess transcriptomic alterations in human bronchial epithelial cells exposed to PM2.5 and better understand how this exposure may lead to a shift from healthy to COPD phenotype. Methods: Normal human bronchial epithelial (NHBE) or COPD cells were differentiated at the air-liquid interface and repeatedly exposed to PM2.5 for 72h. Their transcriptomes were analyzed using human pangenomic microarrays. Results: Basal transcriptomes of both control cell phenotypes were first compared and 1280 transcripts were significantly deregulated in COPD vs NHBE cells. The transcription of 1168 genes was significantly altered by PM2.5 exposure in NHBE cells. Interestingly, among these deregulated mRNA, a large number (679) were in common with those found in shift from NHBE to COPD phenotype. Indeed, within this set of genes, we observed increased expression of genes involved in inflammation (e.g. TGF-b, IL-17, IL-33, CXCL1, CXCL3, CXCL6, CXCL8, CXCL14, CCL20), as well as genes associated with extracellular matrix remodeling (e.g. EGF, FGF1, KRT4, MMP9, MMP 13, TIMP-1). By contrast, only 107 transcripts were modulated by PM2.5 in COPD cells, evidencing an exacerbation of COPD. These alterations were validated by RTqPCR and at functional protein level. Conclusions: Overall these results showed that the transcriptomic alterations induced by PM2.5 exposure deregulated key pathways involved in COPD pathogenesis.
背景:长期暴露于空气污染衍生的细颗粒物(PM2.5)被怀疑会加剧甚至导致慢性炎症性肺病。然而,对基本机制的了解仍然不完整。目的:评估暴露于PM2.5的人类支气管上皮细胞的转录组学变化,并更好地了解这种暴露如何导致从健康表型向COPD表型的转变。方法:正常人支气管上皮(NHBE)或COPD细胞在气液界面分化,并重复暴露于PM2.5 72小时。他们的转录组使用人类全基因组微阵列进行分析。结果:首先比较了两种对照细胞表型的基础转录组,并且在COPD与NHBE细胞中1280个转录组显著失调。在NHBE细胞中暴露于PM2.5显著改变了1168个基因的转录。有趣的是,在这些失调的信使核糖核酸中,大量(679)与从NHBE向COPD表型转变中发现的那些信使核糖核酸相同。事实上,在这组基因中,我们观察到参与炎症的基因(例如TGF-b、IL-17、IL-33、CXCL1、CXCL3、CXCL6、CXCL8、CXCL14、CCL20)以及与细胞外基质重塑相关的基因(如EGF、FGF1、KRT4、MMP9、MMP13、TIMP-1)的表达增加。相比之下,COPD细胞中只有107个转录物被PM2.5调节,证明COPD恶化。通过RTqPCR和功能蛋白水平验证了这些改变。结论:总体而言,这些结果表明,PM2.5暴露诱导的转录组改变解除了参与COPD发病机制的关键途径的调控。

Background: A Mendelian randomisation (MR) study and longitudinal studies have reported the association of lung function with body mass index (BMI). Aim: To investigate whether the association of lung function with BMI is mediated by DNA methylation. Methods: Using data from population-based cohorts (ECRHS, NFBC, SAPALDIA) from the Ageing Lungs in European Cohorts (ALEC) consortium and summary data from published studies, we assessed the mediating role of DNA methylation in the association of lung function with BMI using a 2-step epigenetic MR approach. In step 1 MR, we estimated the causal effect of BMI on peripheral blood DNA methylation (measured at genome-wide level, i.e. >450k CpGs), using 97 BMI-associated SNPs as instrumental variables for BMI in 2,134 participants. In step 2 MR, we estimated the causal effect of DNA methylation on FEV1, FVC, and FEV1/FVC in 7,577 participants (not included in the 1st step) from the same cohorts. As instrumental variables, in this step, we used independent SNPs occurring close (in cis) to 2 CpGs identified in the first step. MR estimates were derived using the Wald ratio, with standard error from the delta method. Results: In step 1, we found that BMI has a small causal effect on DNA methylation levels (less than 1% change in methylation per 1-unit increase in BMI) at 17 CpGs. Of these CpGs, just two were significantly associated with cis-SNPs. In step 2, we found little evidence of a causal effect of DNA methylation at these two sites on lung function. Conclusion: Our findings do not support a mediating effect of DNA methylation in the association of lung function with BMI. However, we were underpowered to detect small effects.

背景:一项孟德尔随机化(MR)研究和纵向研究报告了肺功能与体重指数(BMI)的关系。目的:探讨肺功能与BMI的关系是否由DNA甲基化介导。方法:使用来自欧洲老龄肺队列联盟(ALEC)的基于人群的队列(ECRHS、NFBC、SAPALDIA)的数据和已发表研究的总结数据,我们使用两步表观遗传学MR方法评估了DNA甲基化在肺功能与BMI关联中的介导作用。在步骤1MR中,我们估计了BMI对外周血DNA甲基化的因果影响(在全基因组水平上测量,即>450k CpG),使用97个BMI相关SNPs作为2134名参与者BMI的工具变量。在步骤2MR中,我们估计了来自同一队列的7577名参与者(不包括在第一步中)的DNA甲基化对FEV1、FVC和FEV1/FVC的因果影响。作为工具变量,在这一步中,我们使用了与第一步中鉴定的2个CpG接近(顺式)的独立SNP。MR估计值是使用Wald比率得出的,标准误差来自delta方法。结果:在第1步中,我们发现BMI对17个CpG的DNA甲基化水平有很小的因果影响(BMI每增加1个单位,甲基化变化不到1%)。在这些CpG中,只有两个与顺式SNPs显著相关。在第二步中,我们几乎没有发现这两个位点的DNA甲基化对肺功能有因果影响的证据。结论:我们的研究结果不支持DNA甲基化在肺功能与BMI之间的中介作用。然而,我们在检测小影响方面能力不足。资金:欧盟H2020#633212

Late Breaking Abstract - Mutations of BRWD1 may be associated with Primary Ciliary Dyskinesia 晚期突破性摘要-BRWD1突变可能与原发性睫状体运动障碍有关
IF 1.7 4区 医学 Q2 GENETICS & HEREDITY Pub Date : 2018-09-15 DOI: 10.1183/13993003.CONGRESS-2018.PA1262

Purpose: Patients with Primary Ciliary Dyskinesia (PCD) have been rarely reported in China, and few studies are currently available to characterize the genetic basis of PCD in Chinese families. To identify the potential causative gene in a patient with PCD, who is from a consanguineous Chinese family. Methods: Runs of homozygosity and whole-exome sequencing were conducted on the family. Sanger sequencing was conducted to validate the candidate mutations and familial segregation. Real-time QPCR was used to measure the expression level of the possible causative gene. Zebrafish experiments were performed for candidate gene function verification. Results: A homozygous change in BRWD1, an important developmental gene, that resulted in a missense mutation in the WD-repeat domain of the protein and cosegregated with PCD phenotypes in the family. This mutation in BRWD1 was predicted to be highly deleterious, and qPCR analysis showed a significant and extreme decrease in the expression level of the mutant gene in the affected individual. Morpholino knockdown of brwd1 in zebrafish embryos resulted in situs inversus totalis (a typical phenotype of PCD) and abnormal cardiac looping. Conclusions: BRWD1 was therefore implicated as a novel causative gene for Primary Ciliary Dyskinesia. This homozygous variant was not reported before.
目的:原发性睫状体运动障碍(PCD)患者在中国很少报道,目前也很少有研究能够描述中国家族中PCD的遗传基础。鉴定一位来自中国血亲家庭的PCD患者的潜在致病基因。方法:对该家系进行纯合性和全外显子组测序。进行Sanger测序以验证候选突变和家族分离。实时QPCR用于测量可能致病基因的表达水平。斑马鱼实验用于候选基因功能验证。结果:BRWD1是一种重要的发育基因,其纯合性变化导致蛋白质WD重复结构域发生错义突变,并与家族中的PCD表型共分离。据预测,BRWD1中的这种突变是高度有害的,qPCR分析显示,受影响个体中突变基因的表达水平显著且极端下降。斑马鱼胚胎中brwd1的Morpholino敲低导致总倒位(PCD的一种典型表型)和异常心循环。结论:BRWD1是原发性睫状体运动障碍的一个新的致病基因。这种纯合变体以前没有报道过。

Identification of novel rare genetic variants associated with COPD in the general population 普通人群中与COPD相关的新型罕见遗传变异的鉴定

There are large differences in individual susceptibility to develop COPD, which cannot be explained by common genetic variants. Rare genetic variants, occurring in <1% of the general population, can potentially explain this individual risk to develop COPD. Here, we aim to identify rare genetic variants associated with COPD. Whole genome sequencing was performed on 36 subjects with COPD (FEV 1 /FVC<70% and FEV 1 %pred<90) from the LifeLines general population cohort who had never smoked and were not exposed to environmental smoke or occupational exposures. Rare genetic variants in coding regions with predicted pathogenic effect were selected with the GAVIN algorithm. Variants present in ≥3 subjects were compared with healthy, non-exposed subjects (N=1846) within LifeLines (GoNL imputed data), using a chi 2 test. Next, frequencies of significant variants were further tested in the general population, irrespective of exposures, between healthy (N=10,560) and COPD subjects (N=2,101) from the LifeLines cohort and replicated in the Rotterdam Study (10,897 healthy and 599 COPD subjects). We identified 7,357 predicted pathogenic variants in 5,196 unique genes of which 318 rare genetic variants were carried by ≥3 subjects. 127 of the 318 variants could be imputed in LifeLines and the frequency of 45 variants was significantly different between non-exposed COPD versus non-exposed healthy controls. Next, 5 variants were significantly associated with COPD in the LifeLines population and 2 of these variants, present in ARAP3 and KIF27 , were replicated in the Rotterdam study. Our study is the first to identify rare genetic variants associated with COPD in the general population

Rats are a standard experimental animal for cancer bioassay and toxicological research for chemicals. Although the genetic analyses were behind mice, rats have been more frequently used for toxicological research than mice. This is partly because they live longer than mice and induce a wider variety of tumors, which are morphologically similar to those in humans. The body mass is larger than mice, which enables to take samples from organs for studies on pharmacokinetics or toxicokinetics. In addition, there are a number of chemicals that exhibit marked species differences in the carcinogenicity. These compounds are carcinogenic in rats but not in mice. Such examples are aflatoxin B1 and tamoxifen, both are carcinogenic to humans. Therefore, negative mutagenic/carcinogenic responses in mice do not guarantee that the chemical is not mutagenic/carcinogenic to rats or perhaps to humans. To facilitate research on in vivo mutagenesis and carcinogenesis, several transgenic rat models have been established. In general, the transgenic rats for mutagenesis are treated with chemicals longer than transgenic mice for more exact examination of the relationship between mutagenesis and carcinogenesis. Transgenic rat models for carcinogenesis are engineered mostly to understand mechanisms underlying chemical carcinogenesis. Here, we review papers dealing with the transgenic rat models for mutagenesis and carcinogenesis, and discuss the future perspective.

大鼠是癌症生物测定和化学物质毒理学研究的标准实验动物。虽然遗传分析是在小鼠之后进行的,但大鼠比小鼠更频繁地用于毒理学研究。这在一定程度上是因为它们比老鼠活得更长,而且诱发的肿瘤种类更广泛,这些肿瘤在形态上与人类的肿瘤相似。它的体重比老鼠大,这使得它能够从器官中采集样本,用于药物动力学或毒性动力学的研究。此外,还有一些化学物质在致癌性方面表现出明显的物种差异。这些化合物对大鼠有致癌性,但对小鼠没有。黄曲霉毒素B1和他莫昔芬就是这样的例子,它们都对人类具有致癌性。因此,小鼠的阴性诱变/致癌反应并不能保证该化学物质对大鼠或人类没有诱变/致癌作用。为了促进体内诱变和癌变的研究,已经建立了几种转基因大鼠模型。一般来说,为了更精确地研究诱变与致癌之间的关系,用于诱变的转基因大鼠比转基因小鼠接受更长时间的化学治疗。转基因大鼠致癌模型的设计主要是为了了解化学致癌的机制。在此,我们对转基因大鼠诱变和致癌模型的研究进展进行了综述,并对其发展前景进行了展望。
