Cdkn1a deletion improves stem cell function and lifespan of mice with dysfunctional telomeres without accelerating cancer formation
Aaheli Roy Choudhury,Zhenyu Ju,Meta W. Djojosubroto,Andrea Schienke,André Lechel,Sonja Schaetzlein,Hong Jiang,Anna Stepczynska,Chunfang Wang,Jan Buer,Han Woong Lee,Thomas von Zglinicki,Arnold Ganser,Peter Schirmacher,Hiromitsu Nakauchi,K. Lenhard Rudolph +15 more
TL;DR: It is shown that deletion of p21 prolongs the lifespan of telomerase-deficient mice with dysfunctional telomeres and induces p21-dependent checkpoints in vivo that can limit longevity at the organismal level.
Journal ArticleDOI

TL;DR: It is shown that deletion of the nuclease domain of Exo1 reduces accumulation of DNA damage and DNA damage signal induction in telomere-dysfunctional mice and deletion of ExO1 can prolong survival in the context of telomeres dysfunction.
