摘要
mTOR interacts with multiple proteins involved in major signal transduction pathways controlling cell growth, proliferation, and apoptosis. mTOR is acknowledged to play major roles in cellular interplays between cancer and stroma cells, including endothelial cells. Rapalogues demonstrated antitumour activity in several hypervascularized tumours in clinical trials. Whether rapalogues directly affect cancer cells or other stroma cells in tumours remains poorly understood. Knowing whether rapalogues act directly against cancer cells and/or could be considered as antiangiogenic agents has major implications in terms of medical indications and may help to further improve their drug development. Herein, we hypothesize that current rapalogues demonstrating activity in hypervascularized tumours may primarily act through antiangiogenic effects in patients, a hypothesis that certainly requires further translational investigations.
