Dynamic and functional analyses of exosomal miRNAs regulating cellular microenvironment of ovarian cancer cells.

ABSTRACT:

Background

Exosomes, extracellular vesicles with an average diameter of 30 ~ 150 nm, are pivotal in mediating the cellular microenvironment (CM) through their cargo-carrying capability. Despite extensive studies, the dynamic and regulatory mechanisms of exosomal cargoes, including lipids, proteins, nucleic acids, and metabolites, remain poorly understood.

Methods

In this study, we collected culture medium of ovarian cancer cells at four different time points (12, 24, 36, 48 h). Exosomes were isolated using ultracentrifugation, and miRNA sequencing was performed for exosomes from each group (T12, T24, T36, and T48).

Results

A total of 131 miRNAs were identified in all groups. Specifically, 41, 115, 63, and 24 miRNAs were detected in the T12, T24, T36, and T48 groups, r
