Abstract:Centrosome amplification and chromosome abnormalities are frequently detected in neoplasia and during tumorigenesis; however, the mechanism underlying these defects is still unclear. We here identify that the translational regulator, MCT-1, is a novel proto-oncoprotein located at the spindle-organizing apparatus. Decrease of cellular MCT-1 level results in intercellular bridging, chromosome mis-congregation, cytokinesis delay, and post-mitotic apoptosis. MCT-1 induction alongside p53 deficiency (MCT-1-p53) syn… 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.
