Breast Cancer Exosome Research SolutionOnline Inquiry
Breast cancer originates in the breast tissue and is the most common malignant tumor in women worldwide. Exosomes are extracellular vesicles involved in cellular communication by delivering a variety of bioactive molecules that have been noted to have the ability to alter the transcriptome of target cells and influence tumor-associated signaling pathways. As a type of intercellular communicative vector, exosomes have been extensively investigated in breast cancer biology with respect to invasion, therapeutic resistance, and the surrounding microenvironment. Based on a professional exosome multi-omics analysis platform, we can provide you with comprehensive and reliable breast cancer exosome research solutions, including proteomics, metabolomic and lipidomic analysis services.
Exosome in breast cancer
Breast cancer is a highly heterogeneous disease consisting of many different subtypes that vary in genetics, pathology, and clinical behavior. Exosomes are present in different breast cancer subtypes with a wide range of roles in breast cancer progression.

- Exosomal biomarkers in breast cancer
Since circulating miRNA-loaded exosomes have a good correlation with breast cancer progression, they have been considered ideal biomarkers for this disease. There are many significant exosomal miRNAs that have been highlighted in breast cancer progressions, such as miR-21,miR-16, and miR-223. These exosomal miRNAs may critically impact breast cancer metastasis, drug resistance, immune response, and the formation of the tumor microenvironment.
- Exosomes in breast cancer aggressiveness
Tumor-derived exosomes can promote tumor cell proliferation and metastasis and play an important role in tumor invasion. In addition to promoting tumor cell viability along with extracellular matrix degradation, exosomes promote tumor-tumor communication through chemoresistance delivery. Breast cancer-derived exosomes have been reported to contain annexin A2 and have shown a compelling role in angiogenesis and organ-specific metastasis (especially in brain and lung metastasis).
- Exosomes in breast cancer drug resistance
Growing evidence that tumor cell-secreted exosome levels change in response to anticancer treatment-induced cellular stress, leading to the transfer of drug-resistant phenotypes among breast cancer cells. Therefore, apart from contributing to individualized medical or therapeutic interventions, tumor-derived exosomes can be used as non-invasive biomarkers to explore mechanisms of drug resistance in breast cancer cases.
