Replicative Senescence, Aging and Growth-Regulatory Transcription Factors
1 Jan 1996
Abstract excerpt
Normal somatic cells invariably enter a state of permanent growth arrest and altered function after a finite number of divisions. This phenomenon is termed cellular or replicative senescence. Replicative senescence is thought to be a tumor-suppressive mechanism, and a contributing factor in aging. Three features distinguish senescent from presenescent cells: an irreversible block to cell proliferation, increased...
