Objective

To investigate the correlation between the DNA damage level of the CYTB gene and the arsenic methylation level, FEN1 and XPC gene polymorphism in workers exposed to arsenic.

Methods

A total of 79 workers exposed to occupational arsenic in a coke oven factory in the southern mountainous area of Yunnan Province were selected as the exposure group, and 24 agricultural workers from the same village were selected as the control group. The urine and peripheral blood samples of the subjects were collected.The concentration and percentage of arsenic and its metabolites were detected in the urine, and the DNA damage level of the CYTB gene was detected in peripheral blood.

Results

The concentrations of inorganic arsenic (iAs), monomethylarsonic acid (MMA), and dimethylarsonic acid (DMA) in the urine of the exposure group were higher than those of the control group (P<0.01). The methylation level of the exposure group was significantly higher than that of the control group in terms of MMA% and primary methylation index (PMI), while the DMA% and secondary methylation index (SMI) were significantly lower than those of the control group (P<0.01). Linear regression analysis showed that the DNA damage level of the CYTB gene was positively correlated with MMA% (P< 0.01) and negatively correlated with SMI (P<0.001). The subjects with genotypes AA or GA+AA at the rs174538 locus of the FEN1 gene had significantly higher DNA damage levels of the CYTB gene than those with genotypes GG at this locus (P< 0.05). However, there was no statistical correlation between the genotype of XPC and the level of DNA damage in the CYTB gene (P>0.05).

Conclusion

Occupational arsenic exposure can lead to increased concentrations of arsenic and its metabolites in urine and decreased methylation of arsenic metabolism in the body. The DNA damage of the CYTB gene can be used as a marker of damage and early health damage in the body, and the mutation at the rs174538 locus of the FEN1 gene is associated with DNA damage of the CYTB gene, which can be used as an indicator of disease susceptibility in arsenic-exposed populations.

目的

研究砷暴露工人CYTB基因的DNA损伤水平与甲基化程度、FEN1、XPC基因的多态性之间的相关性。

方法

选取云南省南部山区某焦炉厂存在职业性砷暴露的79名工人作为暴露组,与之同村的24名农业工人作为对照组,采集研究对象的尿液和外周血,检测尿液中砷及其代谢产物的浓度、百分比,检测外周血中CYTB基因的DNA损伤水平。

结果

暴露组尿液中的无机砷(iAs)、单甲基砷酸(MMA)、二甲基砷酸(DMA)的浓度均高于对照组(P均<0.01)。甲基化水平上,暴露组MMA%、一级甲基化指数(PMI)显著高于对照组,DMA%、二级甲基化指数(SMI)显著低于对照组(P均<0.01)。线性回归结果显示CYTB基因的DNA损伤水平与MMA%呈正相关(P<0.01),与SMI呈负相关(P<0.001)。FEN1基因rs174538位点基因型为AA或GA+AA的受试者的CYTB基因DNA损伤水平显著高于该位点基因型为GG的受试者(P<0.05),但XPC的基因型与CYTB基因的DNA损伤水平无统计学相关性(P>0.05)。

结论

焦炉厂工人的职业性砷暴露会导致尿中砷及其代谢产物的浓度增加、体内砷代谢的甲基化程度降低,CYTB基因的DNA损伤可以作为指示体内甲基化水平的受损、早期健康损害的标志物,并且,FEN1基因rs174538位点的突变可以作为砷暴露人群疾病易感性的指标。

目的

研究砷暴露工人CYTB基因的DNA损伤水平与甲基化程度、FEN1、XPC基因的多态性之间的相关性。

方法

选取云南省南部山区某焦炉厂存在职业性砷暴露的79名工人作为暴露组,与之同村的24名农业工人作为对照组,采集研究对象的尿液和外周血,检测尿液中砷及其代谢产物的浓度、百分比,检测外周血中CYTB基因的DNA损伤水平。

结果

暴露组尿液中的无机砷(iAs)、单甲基砷酸(MMA)、二甲基砷酸(DMA)的浓度均高于对照组(P均<0.01)。甲基化水平上,暴露组MMA%、一级甲基化指数(PMI)显著高于对照组,DMA%、二级甲基化指数(SMI)显著低于对照组(P均<0.01)。线性回归结果显示CYTB基因的DNA损伤水平与MMA%呈正相关(P<0.01),与SMI呈负相关(P<0.001)。FEN1基因rs174538位点基因型为AA或GA+AA的受试者的CYTB基因DNA损伤水平显著高于该位点基因型为GG的受试者(P<0.05),但XPC的基因型与CYTB基因的DNA损伤水平无统计学相关性(P>0.05)。

结论

焦炉厂工人的职业性砷暴露会导致尿中砷及其代谢产物的浓度增加、体内砷代谢的甲基化程度降低,CYTB基因的DNA损伤可以作为指示体内甲基化水平的受损、早期健康损害的标志物,并且,FEN1基因rs174538位点的突变可以作为砷暴露人群疾病易感性的指标。

职业性砷暴露  /  CYTB基因  /  DNA损伤水平  /  FEN1基因
Objective

To investigate the correlation between the DNA damage level of the CYTB gene and the arsenic methylation level, FEN1 and XPC gene polymorphism in workers exposed to arsenic.

Methods

A total of 79 workers exposed to occupational arsenic in a coke oven factory in the southern mountainous area of Yunnan Province were selected as the exposure group, and 24 agricultural workers from the same village were selected as the control group. The urine and peripheral blood samples of the subjects were collected.The concentration and percentage of arsenic and its metabolites were detected in the urine, and the DNA damage level of the CYTB gene was detected in peripheral blood.

Results

The concentrations of inorganic arsenic (iAs), monomethylarsonic acid (MMA), and dimethylarsonic acid (DMA) in the urine of the exposure group were higher than those of the control group (P<0.01). The methylation level of the exposure group was significantly higher than that of the control group in terms of MMA% and primary methylation index (PMI), while the DMA% and secondary methylation index (SMI) were significantly lower than those of the control group (P<0.01). Linear regression analysis showed that the DNA damage level of the CYTB gene was positively correlated with MMA% (P< 0.01) and negatively correlated with SMI (P<0.001). The subjects with genotypes AA or GA+AA at the rs174538 locus of the FEN1 gene had significantly higher DNA damage levels of the CYTB gene than those with genotypes GG at this locus (P< 0.05). However, there was no statistical correlation between the genotype of XPC and the level of DNA damage in the CYTB gene (P>0.05).

Conclusion

Occupational arsenic exposure can lead to increased concentrations of arsenic and its metabolites in urine and decreased methylation of arsenic metabolism in the body. The DNA damage of the CYTB gene can be used as a marker of damage and early health damage in the body, and the mutation at the rs174538 locus of the FEN1 gene is associated with DNA damage of the CYTB gene, which can be used as an indicator of disease susceptibility in arsenic-exposed populations.

砷在自然界中广泛存在,多以含砷矿石的形式分布于岩石、土壤和水中,在人类社会中,砷也被广泛用于农药和多种合金的制造。砷及其化合物是世界卫生组织国际癌症研究机构认定的I类致癌物,大量证据表明,砷及其化合物的暴露与皮肤癌、肝癌、肺癌、膀胱癌等恶性肿瘤的发生密切相关[1]。此外,慢性砷暴露也会增加多种心血管疾病[2]、慢性呼吸系统炎症[3]、皮肤损伤[4]等的发病风险。
砷的主要暴露途径包括呼吸道吸入、食物和饮水摄入以及皮肤黏膜吸收。无机砷(inorganic arsenic,iAs)进入人体后,在红细胞内被砷酸还原酶还原为三价砷,然后进入肝脏进行代谢,三价砷在甲基转移酶的催化下生成单甲基砷酸(monomethylarsonous acid,MMA),单甲基砷酸再发生甲基化生成二甲基砷酸(dimethylarsinous acid,DMA)[1],最终经肾脏随尿液排出,因此,尿液中的iAs、MMA和DMA常被用作个体砷暴露的检测指标,而尿液中砷代谢产物的组成比例(iAs%、MMA%、DMA%)则被用于衡量砷在体内代谢的效率和完全程度。
砷在体内的代谢也伴随着毒性的改变,研究表明,砷代谢的甲基化程度与疾病的发生发展密切相关[5-6],个体砷甲基化水平的降低会导致膀胱癌[7]、皮肤癌[8]的发生风险增加。因此,研究砷暴露个体体内的甲基化水平、寻找能够指示其甲基化水平变化的尿或血中的标志物能够对个体健康损害进行早期的提示。
要寻找砷致健康损害的效应标志物,就要从砷的损伤机制出发,氧化应激就是其中的重要机制。砷通过氧化应激直接损伤DNA,导致DNA的破坏、影响DNA的损伤修复,有研究[9]提示,工作环境中的砷暴露会导致细胞色素b(Cytochrome b,CYTB)基因的DNA损伤,CYTB基因为线粒体DNA上的分子标记,由于其较为保守,包含了种内、属间甚至科间的遗传信息,常被用作解决分类学和进化问题的可靠分子标记[10]。在本研究中,我们将引入CYTB基因来检测其DNA损伤水平与砷暴露、砷甲基化代谢之间的关系,并在前期研究基础上,研究FEN1、XPC基因的多态性与CYTB基因的DNA损伤之间的相关性,为CYTB基因的DNA损伤水平成为指示甲基化水平、基因SNP位点多态性指示个体易感性提供一定的依据。
本研究所招募的受试者来自云南省南部的山区,详细的招募方案可见本项目已经发表的论文[11]。本研究得到了昆明医科大学伦理委员会的审查和批准,在向受试者详细解释了研究的目的和流程后,所有受试者均签署了知情同意书。本研究共招募了79名职业性砷暴露的工人作为暴露组和24名与之同村的农业工人作为对照组,暴露组的职业性砷接触来源于焦炉冶炼厂的工作接触、均已暴露超过3个月,对照组的工人居住在距离冶炼厂十余公里的村庄,并且在过去三个月内没有接触过农药。来自昆明医科大学经过针对性培训的工作人员对每位受试者进行了身体检查和访问调查,调查问卷收集的主要信息包括:年龄、性别、职业、岗位、工龄、吸烟饮酒史、疾病史、用药史等,并向受试者采集了5 ml外周血和20 ml尿液,所有生物样品均保存在4 ℃冰箱并尽快转运进行分析。
尿液中砷的测定采用的方法为氢化物发生-火焰原子吸收光谱法,参照WS/T 29-1996标准,使用检测设备为原子吸收分光光度计(AA-6800,Shimadzu Co.,Kyoto,Japan),使用标准品为含有480±100 mg/L砷的冷冻干燥尿液标准参考物质SRM 2670(美国马里兰州盖瑟斯堡国家标准与技术研究所[NIST])。将尿样用混合酸消化、再加入硼氢化钠生成砷化氢,输送到火焰燃烧器上的石英管中,在193.7 nm的波长下进行原子吸收光谱法测定无机砷、单甲基砷酸和二甲基胂酸的浓度,与本项目先前发表的文章一致[11-12]。此外,总砷浓度(total arsenic,tAs),尿砷甲基化代谢物的比例(iAs的百分比,MMA的百分比,DMA的百分比)(iAs%,MMA%,DMA%)和甲基化指数(一级甲基化指数和二级甲基化指数)(Primary methylation index,PMI和Secondary methylation index,SMI)的计算如下[9,13]
tAs=iAs+MMA+DMA;
iAs%=iAs/tAs×100%;
MMA%=DMA/tAs×100%;
DMA%=DMA/tAs×100%;
PMI=(MMA+DMA)/tAs×100%;
SMI=DMA/(MMA+DMA)×100%。
使用试剂盒(天根生物技术(北京)有限公司,中国北京)从获得的受试者外周血样品中提取DNA,然后通过实时荧光定量聚合酶链式反应(Roche LightCycler 96,曼海姆,德国)对每个样品进行一式三份的检测,检测其中CYTB基因DNA的损伤情况。CYTB和内参基因的β-ACTIN引物序列如下:CYTB 上游 5’-GTCATCATCATTCTCACATGGAATC-3’;CYTB 下游 5’-CTCCTTCTCTGGTTTACAAGACCAG-3’;β-ACTIN 上游 5’-CGGGAAATCGTGCGTGACAT-3’;β-ACTIN 下游 5’-GAAGGAAGGCTGGAAGAGTG-3’。PCR的反应条件为:95 ℃ 10 min;95 ℃ 10 s和60 ℃ 10 s共进行35个循环;60 ℃ 5 min。用ΔCt值来反应CYTB基因的损伤情况,计算公式为ΔCt=ΔCtCYTB-ΔCtβ-ACTIN
采用高分辨率熔解的方法在配备了LightScanner HRM系统(Roche,曼海姆,德国)的仪器上检测FEN1 rs174538和XPC rs2228001、rs3731055的基因型,所使用的引物序列如表1所示。反应条件为:95 ℃ 5 min;95 ℃ 10 s,60 ℃ 10 s、72 ℃ 10 s共进行55个循环。
单核苷酸多态性(Single nucleotide polymorphism,SNP)多态性位点基因型数据将通过拟合优度卡方检验(χ2检验)来分析是否符合Hardy-Weinberg平衡定律。调查问卷的数据通过双录入的方法录入数据库,统计学分析采用SPSS 22.0进行。t检验用于评估对照组和暴露组之间的差异;Pearson相关系数和线性回归用于分析DNA损伤水平与尿砷水平之间的相关性;检验水准α=0.05。
本研究共招募了103名研究对象,包括对照组24名农业工人和暴露组79名砷暴露工人,根据收集的调查问卷和尿液样本分析研究对象人口学数据和砷暴露特征如表2所示:对照组和暴露组在年龄、吸烟率和饮酒率上差异无统计学意义;暴露组尿液中的iAs、MMA、DMA浓度均高于对照组,且差异有统计学意义(P<0.01)。
更重要的是,研究对受试者体内的砷代谢程度进行了评估,结果发现,尿中砷及代谢产物的百分比上,暴露组MMA%显著高于对照组,DMA%显著低于对照组,差异有统计学意义(P<0.01),但iAs%在两组之间无差异(P=0.42);砷代谢的甲基化指数上,暴露组的PMI显著高于对照组,但SMI显著低于对照组,差异有统计学意义(P<0.05),与代谢产物的百分比结果一致。
本研究首先检测了对照组和暴露组CYTB基因的DNA损伤水平(见图1A),结果显示,暴露组CYTB基因的DNA损伤水平显著高于对照组,差异有统计学意义(P<0.001)。紧接着,对CYTB基因的DNA损伤水平与个体砷暴露水平之间的相关性进行评估,线性回归分析显示,CYTB基因的DNA损伤水平与受试者尿中iAs、MMA和DMA的浓度呈正相关(见图1B-D),差异有统计学意义(P<0.01)。
进一步地,本研究通过线性回归分析了CYTB基因的DNA损伤水平与砷甲基化水平之间的关系。如图2所示,CYTB基因的DNA损伤水平与MMA%呈正相关(P<0.01),与SMI呈负相关(P<0.001),与DMA%和PMI无统计学相关性(P>0.05)。
对照组和暴露组CYTB基因的DNA损伤水平与FEN1、XPC基因多态性之间的关系如表3所示。其中,FEN1基因rs174538位点基因型为AA或GA+AA的受试者的CYTB基因DNA损伤水平高于该位点基因型为GG的受试者,且差异有统计学意义(P<0.05);但XPC的基因型与CYTB基因的DNA损伤水平无统计学相关性(P>0.05)。本研究也检测了FEN1、XPC基因多态性与甲基化程度之间的关系,各组差异均无统计学意义。
砷对健康的损害与其在体内的代谢密切相关,砷在体内的主要代谢过程是甲基化,甲基化的产物为MMA和DMA,随后经肾脏进行排泄,所以尿中砷的种类和浓度是公认的反映人体砷暴露和代谢模式的重要指标[13]。本研究纳入的受试者为79名在冶炼厂接触砷超过3个月的砷暴露工人(暴露组)和24名来自同一村庄的农业工人(对照组),对其尿砷进行测定后发现,暴露组尿液中的iAs、MMA和DMA的浓度显著高于对照组,证实了尿砷对于近期暴露的敏感性,与预期的结果一致。更重要的是,暴露组尿液中MMA%、PMI显著高于对照组,但DMA%和SMI则相反,说明砷暴露工人体内甲基化水平发生了的改变,即砷的甲基化代谢不完全,累积了毒性较强的MMA。尿中MMA的浓度或百分比是评价人体对砷毒性敏感性的指标,研究表明,MMA%水平的升高会使皮肤损伤、皮肤癌、膀胱癌的发病率显著升高[14-16];并且,砷甲基化水平的降低也与膀胱癌、皮肤癌和其他疾病的发生发展密切相关[7-8]。由此可见,导致砷暴露工人健康损害的原因不仅仅是大量砷在体内的蓄积,也因为砷甲基化代谢不完全而产生的毒性作用。
砷由于其细胞毒性和遗传毒性被认定为I类致癌物,其中,氧化应激是砷致癌的重要机制,砷通过氧化应激直接损伤DNA,因此,DNA损伤是砷致健康损害中的关键效应指标,寻找能够指示该效应的标志物能够帮助识别砷暴露导致的健康损害。Shen等人的研究[9]发现,工作环境中的砷暴露会导致CYTB基因的DNA损伤,CYTB基因为线粒体DNA上较为保守的基因,而线粒体又是氧化应激的主战场。因此,我们将CYTB基因的DNA损伤作为一个效应标志物来检测其与砷暴露、砷代谢之间的关系:在排除了受试者的年龄、性别和生活习惯的影响后,我们发现CYTB基因的DNA损伤水平与尿中砷及其代谢物的浓度呈正相关,与砷的甲基化水平呈负相关。即一方面,本研究证实了砷暴露会导致CYTB基因的DNA损伤,与Shen等人的研究[9]一致,并且,DNA损伤水平与尿中iAs、MMA、DMA的浓度呈线性相关;另一方面,本研究发现,CYTB基因的DNA损伤可以作为一种标志物来指示体内甲基化水平的受损、早期提示砷暴露所致的健康损害的存在。
在明确了CYTB基因的DNA损伤水平能够作为砷致健康损害的效应生物标志物后,我们以它作为效应指标,进一步研究基因多态性对于相同砷暴露条件下个体不同程度健康损害的影响。在前期研究的基础上[11-12],我们选定了两个研究对象,FEN1和XPC基因。FEN1基因编码的蛋白质是一种多功能的核酸酶,在维持基因组的稳定性和预防细胞恶性转化中有重要作用;XPC基因编码的蛋白质是DNA损伤修复系统中核苷酸切除修复途径的早期DNA损伤识别蛋白,在DNA的修复过程中具有关键作用。FEN1和XPC基因存在SNP位点,可能通过SNP位点碱基的改变影响其修复能力和疾病的易感性,许多研究发现FEN1和XPC基因的多态性与多种疾病的风险有关[17-20]。本研究结果表明,XPC基因的多态性与CYTB基因的DNA损伤无明显相关性,但FEN1基因rs174538位点的基因多态性与与CYTB基因的DNA损伤有关,该位点SNP的突变(AA或GA+AA)能够显著增加CYTB基因的DNA损伤,提示FEN1基因rs174538位点的突变可以作为砷暴露人群疾病易感性的指标,但由于受到研究样本数量的限制,仍需更大规模的人群资料来进行验证。
综上,焦炉厂工人的职业性砷暴露会导致尿中砷及其代谢产物的浓度增加、体内砷代谢的甲基化程度降低,CYTB基因的DNA损伤可以作为指示体内甲基化水平的受损、早期健康损害的标志物,并且,FEN1基因rs174538位点的突变与CYTB基因的DNA损伤有关,可以作为砷暴露人群疾病易感性的指标。
