The mechanism of necroptosis in normal and cancer cells

Programmed cell death is a basic cellular process that is critical to maintain tissue homeostasis. Besides apoptosis, necroptosis has more recently been discovered as another form of regulated cell death. Necroptosis plays a pivotal role during normal development and has also been implicated in the pathogenesis of a variety of human diseases. The control of necroptosis by defined signal transduction pathways offers the opportunity to target this cellular process for therapeutic purposes. For example, in cancer necroptosis is often impaired during tumorigenesis and can be engaged by targeted pharmacological approaches. Further insights into the signaling networks involved in the regulation of necroptosis will likely have important implications for the exploitation of this form of programmed cell death for the diagnosis or treatment of many diseases.
