Kanazawa University researchers identify internal structural defects in microtubules

Researchers at Kanazawa University’s Nano Life Science Institute have discovered that tiny structural defects within microtubule walls can trigger their collapse. Using high-speed atomic force microscopy, the team observed these breakdowns even in the presence of paclitaxel, a common cancer drug designed to stabilize the structures.

These findings challenge the conventional scientific understanding that microtubule degradation occurs primarily at their ends. By revealing how internal damage initiates structural failure, this study offers new insights into cell division processes and why cancer cells may exhibit varying responses to chemotherapy treatments that target the cytoskeleton.
