ABSTRACT
Osteosarcoma (OS) commonly metastasizes to the lung, yet the underlying molecular mechanisms remain poorly understood. Exosomes play a crucial role in tumor migration, including OS lung migration. However, the underlying mechanism by which exosome-derived long non-coding RNAs (lncRNAs) contribute to lung migration in osteosarcoma (OS) remains unclear. This study presents a newly discovered lncRNA, linc00881, derived from OS exosomes. Our study shows that linc00881 promotes the migration of OS cells to the lung and induces the conversion of normal lung fibroblasts into cancer-associated fibroblasts (CAFs). Subsequently, we found that exosomal linc00881 secreted by OS cells can regulate the expression of matrix metalloproteinase 2 (MMP2) in HFL-1 cells by sponging miR-29c-3p, thereby activating the NF-κB signaling in lung fibroblasts. Finally, we discovered that pro-inflammatory cytokines, namely IL-1ß, IL-6, and IL-8, were secreted through the linc00881/miR-29c-3p/MMP2 axis. These results suggest that OS-derived exosomes can mediate the intercellular crosstalk between OS cells and lung fibroblasts, ultimately impacting OS lung migration. Our study provides a potential target for the treatment of OS lung migration.
