Abstract:
The primary or acquired cancer chemoresistance is a major problem in the treatment of cancer patients. It could be overcome by non-overlapping treatment regimens such as photodynamic therapy (PDT). PDT is based on the oxidation of cellular components which occurs when a light-excited photosensitizer generates reactive oxygen species (ROS). In this study the effect of mTHPC mediated PDT (mTHPC-PDT) on 5-FU resistant colorectal cancer (CRC) cells HCT116 was investigated. The results show that mTHPC-PDT overcomes 5-FU resistance and is effective against chemoresistant colorectal carcinoma cells.
