Microtubules in Distress (VIDEO) University of South Florida (USF Health) This video is under embargo. Please login to access this video. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Caption This time-lapse video depicts what happens to a mitotic spindle exposed to beta amyloid, a protein associated with Alzheimer's disease. In normal cell division, the red microtubules would stretch out and pull DNA (blue) to opposite ends of the structure. Instead, the microtubules shown here are disrupted and the DNA gets badly mis-localized and lost from the spindle. The result can be an abnormal assortment of genes.
