MARK2 and cancer: Aurora kinases (AURKs) are a class of serine/threonine kinases, which can further be classified into AURKA, AURKB and AURKC.96 Overexpression of the aurora kinases has been observed in many cancer types such as breast cancer,97–100 gastrointestinal cancer,101,102 ovarian cancer103–105 and other tumors,106–108 thereby making these kinases important therapeutic targets to develop selective anticancer agents.
