Aurora-A overexpression leads to override of the microtubule-kinetochore attachment checkpoint.
???displayArticle.abstract???
The amplification of AURORA-A is frequently observed in specific epithelial cell malignancies. The overexpression of aurora-A, a Ser-Thr kinase known to localize to centrosomes during mitosis, appears to imbue cancerous cells with resistance to spindle-checkpoint-targeting drugs such as paclitaxel (Taxol). Indeed, a recent publication by Anand et al. indicates that overexpression of AURORA-A may interfere with spindle-microtubule attachment and disrupt the regulation of the spindle checkpoint by allowing cells with abnormal chromosomal separation to enter anaphase. Thus, the design of new drugs that specifically target aurora-A rather than other checkpoint proteins might alleviate the resistance to Taxol-like clinical therapeutics observed in some tumors.
