Abstract
The effects of the mitotic inhibitor estramustine on the cytoskeleton of DU 145 and AG 1518 cells were studied. Estramustine caused a partial disassembly of microtubules and withdrawal of microtubules from the cell periphery, disorganized microtubules and delayed regrowth of disassembled microtubules. It also induced a spheroid cellular morphology and affected cellular adhesion and survival. Sometimes microtubules seemed to be organized from several microtubule-organizing centers. The cytoskeleton-dependent cell migration was inhibited in the presence of estramustine and the microtubule-interacting vimentin and endoplasmatic reticulum retracted to the perinuclear area. Our results show that not only a complete disassembly of microtubules, but also disturbances of the microtubule network can have dramatic effects on microtubule-dependent processes and localization of cellular organelles. These effects could be of importance in the treatment of prostatic carcinoma with estramustine.
