}We report in this work that the Aβ peptide directly interacts with tubulin close to the vinblastine and GTP/GDP binding site, inhibits the tubulin polymerization rate, induces tubulin aggregation, causes cell shrinking, enhances Mad2, BubR1, p53, and p21 activation in MCF7 cells and induces the apoptotic death of A549, HeLa and MCF7 cells.

Together, these results indicate that by disrupting the interaction between specific kinesins and microtubules and by exerting a direct inhibitory effect on the motor activity, excess Ab deregulates the mechanical forces that govern the spindle and thereby leads to the generation of defective mitotic structures.
