Exosomes can mediate cell-to-cell communication by transferring biological molecules. This study aimed to explore the effect and mechanism of exosomal long non-coding RNA (lncRNA) CHL1-AS1 derived from pM&phis; on EMs.Materials and Methods: Exosomes (exo) from pM&phis; were isolated, identified, and co-cultured with ectopic endometrial stromal cells (eESCs) to investigate the biological functions of pM&phis;-exo. qRT-PCR was used to detect the expression of lncRNA CHL1-AS1 in pM&phis;-exo from EMs and control patients and verify the transportation of lncRNA CHL1-AS1 from pM&phis; to eESCs. The effects of exosomal lncRNA CHL1-AS1 on eESC proliferation, migration, invasion, and apoptosis were also detected. The relationships among lncRNA CHL1-AS1, miR-610, and MDM2 (mouse double minute 2) were verified by dual-luciferase reporter assay. The in vivo experiments were conducted to verify the effects of exosomal lncRNA on EMs using a xenograft model of EMs.Results: Exosomes from pM&phis; were successfully isolated. EMs-pM&phis;-exo promoted eESC proliferation, migration, and invasion and inhibited their apoptosis. lncRNA CHL1-AS1 was upregulated in EMs-pM&phis;-exo and transported from pM&phis; to eESCs via exosomes. lncRNA CHL1-AS1 was found to act as a competing endogenous RNA of miR‑610 to promote the expression of MDM2. EMs-pM&phis;-exo shuttled lncRNA CHL1-AS1 to promote eESC proliferation, migration, and invasion and inhibit apoptosis by downregulating miR-610 and upregulating MDM2. Furthermore, exosomal lncRNA CHL1-AS1 promoted EMs lesions growth by increasing MDM2 in vivo.Conclusion: The results demonstrate that exosomal lncRNA CHL1-AS1 promotes the proliferation, migration, and invasion of eESCs and inhibits their apoptosis by downregulating miR-610 and upregulating MDM2, which might be a potential therapeutic target for EMs.Keywords: endometriosis, peritoneal macrophages, exosomes, lncRNA CHL1-AS1, miR-610, MDM2 |
