Atg4B (gray) and LC3 interaction model.
There is a growing recognition that the process of autophagy has important implications for cancer treatment and tumour recurrence. It is now well established that autophagy is induced when tumour cells are exposed to conditions comparable to those found within growing tumours; conditions which mimic regions of low nutrient status and hypoxia. In addition, many anticancer drugs have been shown to induce autophagy. These studies completed using cell-based assays provide compelling evidence demonstrating an autophagic response in cancer cell lines, but little is known about the response in the context of tumours in patients prior to and following treatment. A primary goal of this project is to determine the relevance and scope of autophagy and autophagy alterations in primary specimens of human cancer. Our goals also include investigating the in vivo effects of autophagy inhibition using mouse models and human tumour xenograft models, and developing selective and potent inhibitors of autophagy.
