Paraoxonase 1 (PON1), a multifactorial antioxidant enzyme, has a defensive role against oxidative stress, which is believed to contribute to cancer development. This study aimed to investigate the association of PON1-L55M functional polymorphism with breast cancer risk.
In the experimental study, blood samples were collected from 150 healthy women controls and 150 breast cancer subjects. The L55M genotyping was performed by polymerase chain reaction-restriction fragment length polymorphism.
Our analysis showed that the genotypes distribution is in Hardy-Weinberg equilibrium for both case and control groups. Our data revealed that there are significant associations between PON1-L55M polymorphism and breast cancer risk in homozygote (OR= 2.13, 95%CI= 1.14-4.00, p= 0.018), dominant (OR= 1.72, 95%CI= 1.07-2.76, p= 0.024), and allelic (OR= 1.55, 95%CI= 1.12-2.15, p= 0.008) models.
Our results suggest that the PON1-L55M genetic variation could be a genetic risk factor for breast cancer risk and it could be considered as a molecular biomarker for screening of susceptible women.

对氧磷酶1(PON1)是一种多因素抗氧化酶,对氧化应激具有防御作用,而氧化应激被认为与癌症的发生发展有关。本研究旨在探讨PON1-L55M功能多态性与乳腺癌风险之间的关联。
在实验研究中,采集了150名健康女性对照者和150名乳腺癌患者的血样。通过聚合酶链反应-限制性片段长度多态性进行L55M基因分型。
我们的分析表明,病例组和对照组的基因型分布均处于哈迪-温伯格平衡。我们的数据显示,在纯合子(OR = 2.13,95%CI = 1.14 - 4.00,p = 0.018)、显性(OR = 1.72,95%CI = 1.07 - 2.76,p = 0.024)和等位基因(OR = 1.55,95%CI = 1.12 - 2.15,p = 0.008)模型中,PON1-L55M多态性与乳腺癌风险之间存在显著关联。
我们的结果表明,PON1-L55M基因变异可能是乳腺癌风险的一个遗传危险因素,可被视为筛查易感女性的分子生物标志物。
