最近的证据表明孕酮在乳腺癌的发展和肿瘤发生中的作用。孕激素通过与其受体相互作用对靶细胞发挥作用;因此,可能导致孕激素受体(PGR)生物学功能改变的遗传变异可能会导致个体对乳腺癌的易感性。据报道,PROGINS等位基因与外显子4中的错义取代(G/T,缬氨酸→亮氨酸,密码子660)完全连锁不平衡,与乳腺癌风险降低相关。在护士健康研究队列中采用巢式病例对照研究设计,我们使用Taqman检测法对1252例病例和1660例匹配对照进行基因分型。我们没有观察到乳腺癌风险与携带G/T(Val 660 →Leu)多态性的任何关联(比值比1.10,95%置信区间0.93-1.30)。此外,我们没有观察到该等位基因与绝经状态和乳腺癌家族史之间的相互作用。总的来说,我们的研究不支持Val 660 →Leu PROGINS多态性与乳腺癌风险之间的关联。
Recent evidence suggests a role for progesterone in breast cancer development and tumorigenesis. Progesterone exerts its effect on target cells by interacting with its receptor; thus, genetic variations, which might cause alterations in the biological function in the progesterone receptor (PGR), can potentially contribute to an individual's susceptibility to breast cancer. It has been reported that the PROGINS allele, which is in complete linkage disequilibrium with a missense substitution in exon 4 (G/T, valine→leucine, at codon 660), is associated with a decreased risk for breast cancer. Using a nested case-control study design within the Nurses' Health Study cohort, we genotyped 1252 cases and 1660 matched controls with the use of the Taqman assay. We did not observe any association of breast cancer risk with carrying the G/T (Val660→Leu) polymorphism (odds ratio 1.10, 95% confidence interval 0.93–1.30). In addition, we did not observe an interaction between this allele and menopausal status and family history of breast cancer as reported previously. Overall, our study does not support an association between the Val660→Leu PROGINS polymorphism and breast cancer risk.
