Abstract:
:We previously reported that the efficacy of photodynamic therapy (PDT) in cell culture was enhanced by ursodeoxycholic acid (UDCA), a nontoxic bile acid. In this study, we examined the ability of UDCA to promote tumor control by PDT in the mouse, using the radiation-induced fibrosarcoma tumor and the photosensitizing agent tin etiopurpurin (SnET2). These experiments revealed that the addition of UDCA to a PDT protocol promoted inhibition of tumor growth, a phenomenon unrelated to either altered SnET2 biodistribution or the level of vascular shutdown during irradiation. These results indicate that UDCA acts solely by promoting direct tumor cell kill by PDT.
