Nucleic acids and proteins carried by exosomes of different origins as potential biomarkers for gynecologic cancers

Abstract

Exosomes are extracellular vesicles with a diameter of 30–150 nm that function in mediating intercellular communication and intercellular material exchange. The liposomal membrane of exosomes protects the cargo carried by exosomes from degradation and assists in transporting cargo to recipient cells to regulate a variety of physiological and pathological processes. The incidence of gynecologic cancers is increasing annually, which is extremely harmful to the lives and health of women because such cancers are challenging to detect at the early stage. Recently, exosomes have emerged as novel biomarkers for diagnosing and predicting the development of gynecologic cancers. In particular, non-coding RNAs (microRNAs [miRNAs], long non-coding RNAs [lncRNAs], and circular RNAs [circRNAs]) carried by exosomes have been extensively investigated in gynecologic cancers. Therefore, the purpose of this review is to focus on the potential roles of exosomes of different origins in ovarian cancer, cervical cancer, and endometrial cancer, which will help to determine the molecular mechanism of carcinogenesis.
