ABSTRACT

For cancer cells to survive during extracellular matrix (ECM)-detachment, they must inhibit anoikis and rectify metabolic deficiencies that lead to the induction of non-apoptotic cell death. Here, we highlight and discuss our recent study implicating receptor-interacting protein kinase-1 (RIPK1) in the induction of mitophagy, the production of reactive oxygen species (ROS) and the consequent elimination of ECM-detached cells.
