Abstract
SUMMARY
OncologySTAT Editorial Team
The p27Kip1 (p27) protein plays an important role in cell cycle regulation during the transition from G1 to S-phase. In many cancers, p27 is functionally inactivated via proteolysis and has been implicated in tumor progression. In breast cancer, aberrant p27 expression has been associated with poor outcome. Evidence suggests that cell cycle arrest by tamoxifen requires normal p27 expression. Results of recent studies showed that high p27 expression is independently predictive of improved relapse-free...
