LncRNA MALAT1 promotes relapse of breast cancer patients with postoperative fever.

This study aims to explore the possible molecular mechanisms underlying the relapse of breast cancer patients with early postoperative fever. Our results indicated plasma levels of lncRNA MALAT1 were elevated in breast cancer patients with early postoperative fever and were associated with RFS. Lipopolysaccharide (LPS) was able to induce fever and systemic inflammatory responses in 4T1 xenograft mice, and promote lung metastasis. But after knocking down lncRNA MALAT1, the inflammatory responses and metastasis of lung were significantly reduced. Moreover, after knocking down lncRNA MALAT1 in the 4T1 cells, TNF-α level in the supernatants was sharply decreased, and the invasion and migration induced by LPS was also weakened. Cumulatively, our data indicates that MALAT1 is closely related to recurrence and metastasis of breast cancer patients with early postoperative fever. PMID: 30416660 [PubMed]
