Genetic characterization of p27Kip1 and stathmin role in controlling cell proliferation in vivo

ABSTRACT: The CDK inhibitor p27Kip1 is a critical regulator of cell cycle progression, but the mechanisms by which p27Kip1 controls cell proliferation in vivo are still not fully elucidated. We recently demonstrated that the microtubule destabilizing protein stathmin is a relevant p27Kip1binding partner involved in the regulation of cell motility. To get more insights into the in vivo significance of this interaction, we generated p27Kip1 and stathmin double knock out (DKO) mice. Interestingly, thorough characterization of DKO mice demonstrated that most of the phenotypes of p27Kip1 null mice linked to the hyperproliferative behavior, such as the increased body and organ weights, the outgrowth of the retina basal layer and the development of pituitary adenomas, were reverted by co-ablation of stath
