摘要

BACKGROUND AND PURPOSE: Cancer stem cells exhibit distinctive cellular metabolism compared with the more differentiated counterparts or normal cells. We aimed to investigate the impact of a novel radionuclide anti-cancer agent (188)Re-Liposome on stemness markers' expression and cellular metabolism in an ovarian cancer model.

MATERIAL AND METHODS: A 2×2 factorial experiment was designed in which factor 1 represented the drug treatment comparing (188)Re-BMEDA, a free form of (188)Re, with (188)Re-Liposome, a nanoparticle-encapsulated form of (188)Re. Factor 2 represented the delivery route, comparing intravenous with intraperitoneal delivery.

RESULTS: Intraperitoneal delivery of (188)Re-Liposome predominantly killed the CSCs-like cells in tumours and switched metabolism from glycolysis to oxidative phosphorylation. Further, intraperitoneal delivery of (188)Re-Liposome treatment was able to block epithelial-to-mesenchymal transition (EMT) and reactivate p53 function. Collectively, these molecular changes led to a striking tumour-killing effect.

CONCLUSIONS: Radionuclides encapsulated in liposomes may represent a novel treatment for ovarian cancer when delivered intraperitoneally (a type of loco-regional delivery). In the future, this concept may be further extended for the treatment of several relevant cancers that have been proved to be suitable for loco-regional delivery of therapeutic agents, such as colon cancer, gastric cancer, and pancreatic cancer.
