Research Abstract

Our study using Aurora inhibitor indicate that Aurora is essentialfor cell division and survival. Several proteins, which are regulated by Aurora kinases,play important roles in mitosis. RNA interference of centrosomal proteins includingAurora A induced cell death, which depended on the checkpoint proteins. The expressionof Aurora A and Plk1 were upregulated in cancer cells, but those of the enzymes whichdegrade them were downregulated.
