P16: P16 is perhaps best known as an indicator of
cellular senescence, a part of the mechanisms that
cause damaged cells or those at the Hayflick limit to become senescent or self - destruct.
An obvious question is how
cellular senescence caused by deficient DNA repair finally affects the aging of a living organism.
The damage that it will repair is the one that is causal in senenscence of DNA pathway (such x-ray radiation
causing senescence) and oncogenic activated
senescence; but not of the type of replicative
senescence (that's the domain of telomeres / telomerase / sub-telomeres and epigenetics) and
cellular replication / proliferation.
It reveals that targeted treatments for acute promyelocytic leukaemia, a rare form of blood cancer,
cause a cascade of molecular events leading to
cellular senescence and recovery.
