TAM-derived exosomal miR-589-3p accelerates ovarian cancer progression through BCL2L13.
Background: Tumor-associated macrophages (TAM) are critical elements of intercellular communication in tumor microenvironment (TME), and exosomes are key mediators between tumor cells and the TME. According to previous reports, miRNAs exert a pivotal role in ovarian cancer (OC) development. The purpose of this work was to explore the function of TAM-derived exosomal miR-589-3p in OC development and elucidate the underlying molecular mechanisms.
Methods: First, peripheral blood mononuclear cells (PBMC) were treated with IL-4 and IL-13 to polarize them into M2-type macrophages. Exosomes were separated from M2-type macrophages, and the physical properties of exosomes were evaluated using transmission electron microscopy (TEM) and nanoparticle tracking analysis (NTA). Next, quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR) was applied to examine the expression of relevant genes. Subsequently, Targetscan and miRDB were utilized to predict miR-589-3p target genes, and then the interaction between miR-589-3p and BCL2L13 was verified by dual luciferase assay and RNA Binding Protein Immunoprecipitation (RIP) assay. Finally, Cell Counting Kit-8 (CCK-8) and flow cytometry experiments were employed to explore the changes in the proliferative and apoptotic abilities of OC cells.
Results: In this research, we demonstrated that TAM-derived exosomes facilitated OC cell proliferation and suppressed OC cell apoptosis. Then, qRT-PCR results indicated that miR-589-3p were markedly elevated after co-culture of TAM-derived exosomes with OC cells. In addition, we discovered that miR-589-3p was bound to BCL-2-like protein 13 (BCL2L13), which was confirmed through luciferase assay and RIP assay. Furthermore, functional analysis displayed that TAM-derived exosomes treated with miR-589-3p inhibitor attenuated the promotion of OC cell progression by exosomes.
Conclusion: TAM-derived exosomal miR-589-3p enhanced OC progression through BCL2L13, which offers a novel for OC therapy.
期刊介绍：
Journal of Ovarian Research is an open access, peer reviewed, online journal that aims to provide a forum for high-quality basic and clinical research on ovarian function, abnormalities, and cancer. The journal focuses on research that provides new insights into ovarian functions as well as prevention and treatment of diseases afflicting the organ.
Topical areas include, but are not restricted to:
Ovary development, hormone secretion and regulation
Follicle growth and ovulation
Infertility and Polycystic ovarian syndrome
Regulation of pituitary and other biological functions by ovarian hormones
Ovarian cancer, its prevention, diagnosis and treatment
Drug development and screening
Role of stem cells in ovary development and function.
