Atg7 deficiency increases resistance of MCF-7 human breast cancer cells to photodynamic therapy

Abstract excerpt

Photodynamic therapy (PDT) uses a photosensitizer, light and oxygen to produce extensive oxidative damage to organelles housing the photosensitizer. Although PDT is an efficient trigger of apoptosis, it also induces autophagy in many kinds of cells. Autophagy can serve as both a cell survival and a cell death mechanism. Our previous study indicates that autophagy contributes to cell death after PDT, especially in...
