Interaction between BCSG1 and Hsa-circ-0026352 in genetic susceptibility to invasive breast cancer / 中国肿瘤生物治疗杂志

@#[摘 要] 目的：探讨乳腺癌特异基因1（BCSG1）与Hsa-circ-0026352在浸润性乳腺癌（IBC）遗传易感性中的交互作用。方法：选取2019年6月至2022年5月间武汉市中西医结合医院收治的100例IBC患者作为研究对象，采用免疫组化法检测IBC组织及其相应癌旁组织中BCSG1的表达，将研究对象按照IBC组织中BCSG1蛋白表达的高低分为阴性、弱阳性和强阳性组，统计三组患者的临床病理特征及雌激素受体（ER）、孕激素受体（PR）、表皮生长因子受体-2（HER2）、Hsa-circ-0026352的表达情况，采用Logistic回归方程和最大似然法分析BCSG1表达与上述参数的趋势性和交互作用。结果：与癌旁组织比较，IBC组织中BCSG1蛋白呈高表达（P<0.05）；BCSG1蛋白强阳性表达与淋巴结转移、分化程度、临床分期、HER2表达、 Hsa-circ-0026352表达有关联（P<0.05）；BCSG1强阳性表达与IBC存在交互作用（P<0.05）；BCSG1表达与IBC的交互作用在Hsa-circ-0026352阳性表达中最为显著（趋势P<0.001）；BCSG1表达与IBC的交互作用在临床分期Ⅲ期、低分化程度中最为显著（趋势P<0.001）。结论：BCSG1与IBC患病密切相关，且与Hsa-circ-0026352、临床分期、分化程度存在交互作用，可共同增加IBC患病风险性。

polymorphism of angiotensin-receptor gene A1166C in familial hypertension and its distribution in the Han Yellow race of China

To study the polymorphism of angiotensin-type 1 receptor [AT1R] gene A1166C in familial primary hypertension and its distribution in Han Yellow race of China. One hundred and four hypertensive patients with no family history, 178 hypertensive patients with familial history, and 150 healthy adults were randomly selected to participate in a prospective clinical trial, and genetype detection by standard polymerase chain reaction methods and restriction fragment length polymorphism [PCR-RFLP] in trials. The study was carried out between October 2009 and November 2010 at Jinan Center for Cardiovascular Disease, Affiliated Hospital of Taishan Medical College, Jinan, China. Notable statistical significances exist in the frequency of genotype and allele of A1166C in familial hypertension group [x[2]=7.663, p=0.020] compared with the normal control group [x[2]= 8.288, p=0.004]. No significant difference was found in the hypertension group [x[2] = 2.186, p=0.322] compared with the normal control group [x[2]=1.289, p=0.256] in the frequency of genotype and allele of A1166C. No significant differences were found between various ages or genders in each of the 3 groups in genotype and allele of A1166C [p>0.05] distribution. In the Han Yellow race population of China, the frequency of genotype and allele of A1166C of patients with familial hypertension is higher than that of healthy adults. The distribution of AT1R gene polymorphisms of A1166C is not related to age or gender
