中文摘要

滋养层细胞表面抗原2(TROP2)是一种钙信号转导蛋白和跨膜糖蛋白,本研究在三阴性乳腺癌(TNBC)患者中对其表达进行了研究。mRNA表达、免疫组织化学和免疫荧光分析显示,TNBC组织中TROP2表达较高。对TNBC样本中的TIL(肿瘤浸润淋巴细胞)进行了评估,计算机模拟研究显示TROP2表达与CD4+细胞浸润之间存在显著关联。Kaplan-Meier生存分析发现,TROP2表达是生存的独立决定因素,TROP2高表达组具有更好的生存获益。我们的研究为针对TNBC患者靶向TROP2的新疗法开辟了道路。

Trophoblast Cell-surface antigen 2 (TROP2), a calcium signal transducer & a transmembrane glycoprotein expression was studied in Triple-Negative Breast Cancer (TNBC) patients. mRNA expression, immunohistochemical and immunofluorescence analysis illustrated a higher TROP2 expression in the TNBC tissues. Assessment of tumor-infiltrating lymphocytes in TNBC samples was done and in silico studies depicted a significant association between TROP2 expression and infiltration of CD4+ cells. Kaplan-Meier survival analysis observed TROP2 expression to be an independent determinant of survival, with better survival benefit in the TROP2 high group. Our study paves the way for newer therapies targeting TROP2 for TNBC patients.
