Abstract:

Extracellular vesicle (EV) is widely distributed and fully involved in the regulation of various aspects of cellular physiology. As active carriers of molecular biomarkers and mediators of intercellular communication,EV is involved in the occurrence,development,metastasis,drug resistance and other links of tumors. The EV,which can be obtained from a variety of body fluids and are highly homologous to tissues,plays an important role in the maintenance of cell homeostasis and the exchange of substances and information between cells,thus becoming an ideal biomarker for tumor diagnosis and treatment. In the emerging liquid biopsy application,EV DNA can be used as a molecular marker for the diagnosis and prognosis evaluation of many kinds of tumors,and it is the most potential molecular marker of liquid biopsy in the field of tumor diagnosis and treatment.

Key words: Extracellular vesicles, Neoplasms, DNA
