P19 senescence

WebOct 13, 2014 · These cell culture results suggest that senescence is a barrier to transformation and are supported by studies showing that mice lacking p19 Arf 23 or p16 Ink4a 24 are predisposed to cancer. Many stimuli leading to a DDR can also induce apoptosis, which is a form of programmed cell death. WebMutations at the INK4alocus often disrupt both p16 and p19 ARF (for review, seeHaber 1997) and mice lacking p19 ARF develop tumors (Kamijo et al. 1997). p19 ARF also promotes cell-cycle arrest and primary cells derived from ARF-deficient mice can be transformed by oncogenic Ras alone (Kamijo et al. 1997).
