摘要
背景:乳腺癌(BC)是女性发病率最高的癌症。目的:研究乳腺癌患者的血浆 miRNA 水平,并评估其与绝经状态、疾病分期和分子 BC 亚型的相关性:采用RT-PCR方法研究了70名BC患者和18名健康人血浆中6种miRNA(miRNA-25、miRNA-27、miRNA-155、miRNA-200、miRNA-335和miRNA-497)的水平。结果发现:在 BC 患者中,miRNA-25、miRNA-335 和 miRNA-497 的水平明显较高,而在绝经前患者中,miRNA-27 和 miRNA-335 的水平呈下降趋势,在绝经期患者中,miRNA-27 的水平较高。新辅助化疗后,miRNA-25和miRNA-335水平有所下降:结果表明,miRNA-25、miRNA-27、miRNA-335和miRNA-497作为评估BC患者疗效的标志物值得关注。
ASSESSMENT OF CIRCULATING miRNA LEVELS IN BREAST CANCER PATIENTS DEPENDING ON CLINICAL CHARACTERISTICS AND CHEMOTHERAPY.
Background: Breast cancer (BC) stands out as the most prevalent cancer in women. The levels of miRNA expression before and after chemotherapy are considered a potential indicator for the prognosis of the disease.
Aim: To study blood plasma miRNA levels in BC patients and to assess their correlation with the menopausal status, disease stage, and molecular BC subtype.
Materials and methods: Blood plasma levels of 6 miRNAs (miRNA-25, miRNA-27, miRNA-155, miRNA-200, miRNA-335, and miRNA-497) were studied in 70 BC patients and 18 healthy individuals using RT-PCR.
Results: miRNA-25, miRNA-335, and miRNA-497 levels were significantly higher in BC patients, while a tendency toward a decrease in the miRNA-27 and miRNA-335 levels in premenopausal patients and high miRNA-27 levels in menopausal patients was established. After neoadjuvant chemotherapy, a decrease in the miRNA-25 and miRNA-335 levels was registered.
Conclusions: The results indicated that miRNA-25, miRNA-27, miRNA-335, and miRNA-497 deserve attention as markers for assessing the efficacy of treatment of BC patients.
