摘要
Pancreatic ductal adenocarcinoma is one of the most aggressive solid tumours of the pancreas, characterised by a fve-year survival rate less than 8%. Recent reports that pancreatic cancer stem cells （PCSCs） contribute to the tumorigenesis, progression, and chemoresistance of pancreatic cancer have prompted the investigation of new therapeutic approaches able to directly target PCSCs. In the present paper the non-cancer related drugs that have been proposed to target CSCs that could potentially combat pancreatic cancer are revi-ewed and evaluated. The role of some pathways and deregulated proteins in PCSCs as new therapeutic tar-gets are also discussed with a focus on selected speci-fic inhibitors. Finally, advances in the development of nanoparticles for targeting PCSCs and site-specifc drug delivery are highlighted, and their limitations considered.
Pancreatic ductal adenocarcinoma is one of the most aggressive solid tumours of the pancreas, characterised by a five-year survival rate less than 8%. Recent reports that pancreatic cancer stem cells(PCSCs) contribute to the tumorigenesis, progression, and chemoresistance of pancreatic cancer have prompted the investigation of new therapeutic approaches able to directly target PCSCs. In the present paper the non-cancer related drugs that have been proposed to target CSCs that could potentially combat pancreatic cancer are reviewed and evaluated. The role of some pathways and deregulated proteins in PCSCs as new therapeutic targets are also discussed with a focus on selected specific inhibitors. Finally, advances in the development of nanoparticles for targeting PCSCs and site-specific drug delivery are highlighted, and their limitations considered.
