Abstract:Background: BAL0891 is a dual inhibitor of threonine tyrosine kinase (TTK) and polo-like kinase 1 (PLK1). These kinases collaborate in activating the mitotic spindle assembly checkpoint (SAC) at the kinetochore (KT) to regulate chromosome alignment and segregation prior to mitotic exit. In vitro, BAL0891 has a combined prolonged effect on TTK and a transient effect on PLK1, leading to rapid disruption of the SAC that potentiates aberrant mitotic progression of tumor cells. In this work, efficacy of BAL0891 was… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
