ABSTRACT
Photodynamic therapy (PDT) using the photosensitizer Photofrin is approved for the clinical treatment of solid tumors. PDT causes cytotoxic oxidative stress, but additionally induces prosurvival molecules such as cyclooxygenase-2 (COX-2). Combining PDT with COX-2 inhibitors increases the efficacy of in vivo treatment. Understanding mechanisms leading to prosurvival molecule induction is relevant to the design of more effective treatments. Using COX-2 promoter constructs, transcription factor-binding assays, identification of protein kinase activation, and inhibitors of transcription factor binding we were able to determine that COX-2 expression following PDT involves the p38 MAP kinase pathway.
