Mice deficient in p27kip are viable and larger than normal littermates, with increased cellularity of all tissues. The thymus and spleen are particularly enlarged. Nullizygous adult mice have a shortened lifespan due to the growth of benign intermediate lobe pituitary tumors. Female mice are infertile, with a follicular phase ovulatory block. Large doses of exogenous gonadotropin induce ovulation, but both implantation and intrauterine embryonic development is impaired. The mice demonstrate haploid-insufficient susceptibility to the development of adenomas in the pituitary, intestine and lung adenomas following exposure to gamma irradiation or chemical carcinogens.
