Low Molecular Weight Cyclin E Overexpression Shortens Mitosis, Leading to Chromosome Missegregation and Centrosome Amplification

Abstract excerpt

Overexpression of the low molecular weight isoforms (LMW-E) of cyclin E induces chromosome instability; however, the degree to which these tumor-specific forms cause genomic instability differs from that of full-length cyclin E (EL), and the underlying mechanism(s) has yet to be elucidated. Here, we show that EL and LMW-E overexpression impairs the G(2)-M transition differently and leads to different degrees of...
