The rodent Pig-a assay has been used extensively as a potential regulatory assay for evaluating the in vivo mutagenicity of test substances. Although the assay can be conducted in different mammalian species, there have been only a few reports describing its use in humans, and rarely in genotoxicant-exposed human populations. In this study, PIG-A mutation frequencies (MFs) were evaluated in 36 azathioprine (AZA; human carcinogen)-treated inflammatory bowel disease (IBD) patients and 36 healthy volunteers. IBD patients exhibited a slight but statistically higher MF (6.10 ± 4.44 × 10-6 ) than healthy volunteers (4.97 ± 2.74 × 10-6 ) (P = 0.0489). The estimated relative risk for the exposed patients was 1.22 which indicated that AZA is a risk factor for inducing PIG-A mutation. However, the PIG-A MF showed no associations with AZA treatment duration or total AZA exposure. In addition, we performed the cytokinesis-block micronucleus test on the same samples. The frequencies of micronuclei (MN) and nuclear buds (NBUD) in IBD patients (MN: 4.70 ± 2.86‰; NBUD: 1.89 ± 0.95‰) were significantly higher than in healthy volunteers (MN: 1.47 ± 0.77‰, P < 0.001; NBUD: 0.90 ± 0.58‰, P = 0.004). MN frequency also had significant correlations with AZA treatment duration (P = 0.011) and total AZA exposure (P = 0.018). Our findings indicate that AZA-treated IBD patients have only a marginally significant increase in PIG-A MF; in contrast, a much stronger AZA-associated increase in genotoxicity was detected with the lymphocyte MN assay.

人PIG-A分析在硫唑嘌呤治疗的炎症性肠病患者中的潜在应用。

啮齿动物Pig-a测定法已广泛用作评估测试物质在体内致突变性的潜在调节测定法。尽管该测定法可以在不同的哺乳动物物种中进行,但只有少数报道描述了其在人类中的用途,很少在有基因毒性的人群中使用。在这项研究中,评估了36名硫唑嘌呤(AZA;人类致癌物)治疗的炎症性肠病(IBD)患者和36名健康志愿者的PIG-A突变频率(MFs)。IBD患者的MF(6.10±4.44×10-6)略高于健康志愿者(4.97±2.74×10-6)(P = 0.0489)。暴露患者的估计相对风险为1.22,这表明AZA是诱导PIG-A突变的危险因素。然而,PIG-A MF与AZA治疗持续时间或总AZA暴露量无关。此外,我们对相同样品进行了胞质分裂阻滞微核试验。IBD患者的微核(MN)和核芽(NBUD)频率(MN:4.70±2.86‰; NBUD:1.89±0.95‰)显着高于健康志愿者(MN:1.47±0.77‰,P <0.001; NBUD:0.90±0.58‰,P = 0.004)。MN频率也与AZA治疗持续时间(P = 0.011)和总AZA暴露量(P = 0.018)有显着相关性。我们的发现表明,AZA治疗的IBD患者的PIG-A MF仅略有增加;相比之下,淋巴细胞MN测定法检测到了与AZA相关的更强的遗传毒性。环境。大声笑 诱变剂。2019.©2019 Wiley Periodicals,Inc. 我们对相同样品进行了胞质分裂阻滞微核试验。IBD患者的微核(MN)和核芽(NBUD)频率(MN:4.70±2.86‰; NBUD:1.89±0.95‰)显着高于健康志愿者(MN:1.47±0.77‰,P <0.001; NBUD:0.90±0.58‰,P = 0.004)。MN频率也与AZA治疗持续时间(P = 0.011)和总AZA暴露量(P = 0.018)有显着相关性。我们的发现表明,AZA治疗的IBD患者的PIG-A MF仅略有增加;相比之下,淋巴细胞MN测定法检测到与AZA相关的遗传毒性增加得多。环境。大声笑 诱变剂。2019.©2019 Wiley Periodicals,Inc. 我们对相同样品进行了胞质分裂阻滞微核试验。IBD患者的微核(MN)和核芽(NBUD)频率(MN:4.70±2.86‰; NBUD:1.89±0.95‰)显着高于健康志愿者(MN:1.47±0.77‰,P <0.001; NBUD:0.90±0.58‰,P = 0.004)。MN频率也与AZA治疗持续时间(P = 0.011)和总AZA暴露量(P = 0.018)有显着相关性。我们的发现表明,AZA治疗的IBD患者的PIG-A MF仅略有增加;相比之下,淋巴细胞MN测定法检测到了与AZA相关的更强的遗传毒性。环境。大声笑 诱变剂。2019.©2019 Wiley Periodicals,Inc. 70±2.86‰; NBUD:1.89±0.95‰)显着高于健康志愿者(MN:1.47±0.77‰,P <0.001; NBUD:0.90±0.58‰,P = 0.004)。MN频率也与AZA治疗持续时间(P = 0.011)和总AZA暴露量(P = 0.018)有显着相关性。我们的发现表明,AZA治疗的IBD患者的PIG-A MF仅略有增加;相比之下,淋巴细胞MN测定法检测到了与AZA相关的更强的遗传毒性。环境。大声笑 诱变剂。2019.©2019 Wiley Periodicals,Inc. 70±2.86‰; NBUD:1.89±0.95‰)显着高于健康志愿者(MN:1.47±0.77‰,P <0.001; NBUD:0.90±0.58‰,P = 0.004)。MN频率也与AZA治疗持续时间(P = 0.011)和总AZA暴露量(P = 0.018)有显着相关性。我们的发现表明,AZA治疗的IBD患者的PIG-A MF仅略有增加;相比之下,淋巴细胞MN测定法检测到了与AZA相关的更强的遗传毒性。环境。大声笑 诱变剂。2019.©2019 Wiley Periodicals,Inc. 我们的发现表明,AZA治疗的IBD患者的PIG-A MF仅略有增加;相比之下,淋巴细胞MN测定法检测到与AZA相关的遗传毒性增加得多。环境。大声笑 诱变剂。2019.©2019 Wiley Periodicals,Inc. 我们的研究结果表明,AZA治疗的IBD患者的PIG-A MF仅略有增加;相比之下,淋巴细胞MN测定法检测到与AZA相关的遗传毒性增加得多。环境。大声笑 诱变剂。2019.©2019 Wiley Periodicals,Inc.
