Zusammenfassung: <jats:title>Abstract</jats:title> <jats:p>Cellular senescence, a permanent cell cycle arrest, is considered a safeguard mechanism that may prevent aged or abnormal cells from further expansion. Although the term “replicative senescence” stands for the widely accepted model of a terminal growth arrest due to telomere attrition, the significance of “oncogene-inducible senescence” remained an issue of debate over the years. A number of recent studies now show the effect of this acute and telomere-independent form of senescence as a tumor-protective, fail-safe mechanism in vivo that shares conceptual and possibly therapeutic similarities with the genetically encoded apoptosis machinery.
