Objective: The aim is to use the technique called Photochemical Internalisation (PCI), a light-triggered intracellular drug delivery method which combines low dose PhotodynamicTherapy (PDT) with chemotherapy, to induce efficient cytosolic delivery of therapeutic compounds to their specific subcellular targets.
Summary: Observation of minimal cytotoxicity induced by saporin, gemcitabine or TPPS2a+ light monotherapies. However, PCI synergistically enhanced saporin and gemcitabine cytotoxicity (p<0.001) using very low concentrations in all tumor models. Findings demonstrate the potential of PCI to enhance the efficacy of cancer chemotherapy for pancreatic cancer using lower doses than in monotherapy and open a new window for future translational studies.
Usage: Saporin was used as monotherapy or in combination with a light-activated photosensitizer.
