Abortive Apoptosis and Its Profound Effects on Radiation, Chemical, and Oncogene-Induced Carcinogenesis

Abstract: Traditionally apoptosis and the apoptotic machinery have been deemed as anti-carcinogenic because of their presumed roles in eliminating damaged or unwanted cells. However, recent work from our laboratory and others have shown that the established paradigm is deeply flawed. The fundamental flaw is the assumption that apoptosis, once initiated, is irreversible and invariably leads to cell death. However, there is increasing evidence that cells can survive activation of the apoptotic cascade. T…
