摘要: Circulating microRNAs (miRNAs) have been extensively studied in cancer as biomarkers but little is known regarding the influence of anti-cancer drugs on their expression levels. In this article, we describe modifications circulating miRNAs profile after neoadjuvant chemotherapy (NAC) for breast cancer. The 188 was assessed plasma 25 patients before and NAC by RT-qPCR. Two miRNAs, miR-34a miR-122, that were significantly increased NAC, measured tumor tissue 7 with pathological partial response (pPR) to NAC. These two chemotherapy-induced further 22 adjuvant (AC) well 12 who did not receive any chemotherapy. Twenty-five modified Among these miR-122 highly upregulated, notably pPR aggressive Furthermore, level elevated remaining treatment. Studying kinetics during revealed levels especially anthracycline-based Comparisons miRNA profiles AC suggested originated from both tumoral non-tumoral compartments. This study first demonstrate specifically induces tissue, which might be involved anti-tumor effects patients. J. Cell. Physiol. 230: 473–481, 2015. © 2014 Wiley Periodicals, Inc.
