Abstract

The second most pervasive cancer affecting the survival of women across the world is breast cancer. One of the biggest challenges in breast cancer treatment is the chemoresistance of cancer cells to various medications after some time. Therefore, highly specific blood-based biomarkers are required for early breast cancer diagnosis to overcome chemoresistance and improve patient survival. These days, exosomal miRNAs have attracted much attention as early diagnostic blood-based biomarkers because of their high stability, secretion from malignant tumor cells, and excellent specificity for different breast cancer subtypes. In addition, exosomal miRNAs regulate cell proliferation, invasion, metastasis, and apoptosis by binding to the 3'UTR of their target genes and limiting their production. This review focuses on the functions of exosomal miRNAs in tumorigenesis via targeting multiple signaling pathways as well as chemosensitivity and resistance mechanisms. In addition, the growing pieces of evidence discussed in this review suggest that circulating exosomal miRNAs could be utilized as potential next-generation therapeutic target vehicles in the treatment of breast cancer.

外体miRNA作为癌症下一代治疗载体。

影响全世界妇女生存的第二大癌症是癌症。癌症治疗的最大挑战之一是癌症细胞在一段时间后对各种药物的化疗耐药性。因此，癌症早期诊断需要高度特异性的血液生物标志物，以克服化疗耐药性并提高患者生存率。近年来，外泌体miRNA作为早期诊断血液生物标志物，由于其高稳定性、从恶性肿瘤细胞分泌以及对不同的乳腺癌症亚型具有优异的特异性，引起了人们的广泛关注。此外，外泌体miRNA通过与靶基因的3'UTR结合并限制其产生来调节细胞增殖、侵袭、转移和凋亡。本文综述了外泌体miRNA通过靶向多种信号通路以及化疗敏感性和耐药性机制在肿瘤发生中的作用。此外，本综述中讨论的越来越多的证据表明，循环外泌体miRNA可作为潜在的下一代治疗靶向载体用于治疗癌症。

期刊介绍： Current Gene Therapy is a bi-monthly peer-reviewed journal aimed at academic and industrial scientists with an interest in major topics concerning basic research and clinical applications of gene and cell therapy of diseases. Cell therapy manuscripts can also include application in diseases when cells have been genetically modified. Current Gene Therapy publishes full-length/mini reviews and original research on the latest developments in gene transfer and gene expression analysis, vector development, cellular genetic engineering, animal models and human clinical applications of gene and cell therapy for the treatment of diseases. Current Gene Therapy publishes reviews and original research containing experimental data on gene and cell therapy. The journal also includes manuscripts on technological advances, ethical and regulatory considerations of gene and cell therapy. Reviews should provide the reader with a comprehensive assessment of any area of experimental biology applied to molecular medicine that is not only of significance within a particular field of gene therapy and cell therapy but also of interest to investigators in other fields. Authors are encouraged to provide their own assessment and vision for future advances. Reviews are also welcome on late breaking discoveries on which substantial literature has not yet been amassed. Such reviews provide a forum for sharply focused topics of recent experimental investigations in gene therapy primarily to make these results accessible to both clinical and basic researchers. Manuscripts containing experimental data should be original data, not previously published.
