Abstract
Centrosomes are frequently amplified in cancer cells, but centrosome clustering pathways act to minimize their detrimental impact on mitosis. Recent data published online in Genes & Developments by Kwon et al. (2008) suggest that these pathways involve microtubule motors, actin, and focal adhesions. Since centrosomal amplification is rarely seen in normal cells, could blocking clustering lead to the selective killing of tumor cells?
