Abstract: Aurora B, Which is important for cell division control, is highly expressed in large number of cancer cell lines. Hesperadin, a prototype of a pharmacological agent, is a small molecule inhibitor of catalytic activity of Aurora B. In present work we investigate effect of Hesperadin on breast – MCF7 and prostate adenocarcioma – PC3, cancer cell lines. After Hesperadin treatment we observe stop of cell proliferation due to appearance of multiple mitotic defects caused by Aurora B. Activity reduction and elimination of checkpoint proteins – such as hBUBR1 and CENP-E – fron kinotochores of mitotic chromosomes/
