ABSTRACT
Extracellular vesicular long noncoding RNAs (lncRNAs) to influence recipient cells is emerging as a novel mechanism for disease progression. TC0101441 is a newly identified metastasis-related lncRNA involved in cancer. Since endometriosis exhibits prometastasis behavior similar to those observed in cancer, we aimed to investigate whether TC0101441 is involved in endometriosis and, if so, whether extracellular vesicular TC0101441 contributes to the migration/invasion of endometriotic cyst stromal cells (ECSCs). Clinically, we found that TC0101441 was highly expressed in ectopic endometria than in the eutopic and normal endometria. Serum extracellular vesicular TC0101441 levels were substantially increased in patients at stage III/IV endometriosis in comparison with stage I/II endometriosis and controls. In vitro, using TC0101441-high-expression ECSCs (ECSCs-H) as extracellular vesicles (EVs)-generating cells and TC0101441-low-expression ECSCs (ECSCs-L) as recipient cells, we observed that the PKH67-labeled ECSCs-H-derived EVs were effectively internalized by ECSCs-L. ECSCs-H-derived EVs shuttling TC0101441 were transferred to ECSCs-L, modulating their migratory/invasive abilities partially by regulating certain metastasis-related proteins, which eventually facilitated endometriosis migration/invasion. This study elucidates a potential crosstalk between ECSCs via EVs in endometriotic milieus, suggests a novel mechanism for endometriosis migration/invasion from the perspective of the "extracellular vesicular transfer of lncRNAs" and highlights the potential of circulating extracellular vesicular TC0101441 as a biomarker for endometriosis.
