Cellular and molecular effects of the liposomal mTHPC derivative Foslipos in prostate carcinoma cells in vitro.

Background: Meso-tetra-hydroxyphenyl-chlorine (mTHPC) is among the most powerful photosensitizers available for photodynamic therapy (PDT). However, the mechanisms leading to cell death are poorly understood. We here focused on changes at DNA and RNA levels after treatment with the liposomal mTHPC derivative Foslipos in vitro.
