Absolute quantification of somatic DNA alterations in human cancer
We describe a computational method that infers tumor purity and malignant cell ploidy directly from analysis of somatic DNA alterations. The method, named ABSOLUTE, can detect subclonal heterogeneity… Expand

A Mechanism Linking Extra Centrosomes to Chromosomal Instability
Chromosomal instability (CIN) is a hallmark of many tumours and correlates with the presence of extra centrosomes. However, a direct mechanistic link between extra centrosomes and CIN has not been… Expand

DNA breaks and chromosome pulverization from errors in mitosis
The involvement of whole-chromosome aneuploidy in tumorigenesis is the subject of debate, in large part because of the lack of insight into underlying mechanisms. Here we identify a mechanism by… Expand

Mechanisms to suppress multipolar divisions in cancer cells with extra centrosomes.
Multiple centrosomes in tumor cells create the potential for multipolar divisions that can lead to aneuploidy and cell death. Nevertheless, many cancer cells successfully divide because of mechanisms… Expand

Cell cycle control of kinesin-mediated transport of Bik1 (CLIP-170) regulates microtubule stability and dynein activation.
CLIPs are microtubule plus end-associated proteins that mediate interactions required for cell polarity and cell division. Here we demonstrate that budding yeast Bik1, unlike its human ortholog… Expand

Cytokinesis failure generating tetraploids promotes tumorigenesis in p53-null cells
A long-standing hypothesis on tumorigenesis is that cell division failure, generating genetically unstable tetraploid cells, facilitates the development of aneuploid malignancies. Here we test this… Expand

Yeast formins regulate cell polarity by controlling the assembly of actin cables
Formins are conserved Rho-GTPase effectors that communicate Rho-GTPase signals to the cytoskeleton. We found that formins were required for the assembly of one of the three budding yeast actin… Expand

An actin nucleation mechanism mediated by Bni1 and Profilin
Formins are required for cell polarization and cytokinesis, but do not have a defined biochemical activity. In Saccharomyces cerevisiae, formins and the actin-monomer-binding protein profilin are… Expand

From polyploidy to aneuploidy, genome instability and cancer
Polyploidy is a frequent phenomenon in the eukaryotic world, but the biological properties of polyploid cells are not well understood. During evolution, polyploidy is thought to be an important… Expand

Plus end-specific depolymerase activity of Kip3, a kinesin-8 protein, explains its role in positioning the yeast mitotic spindle
The budding yeast protein Kip3p is a member of the conserved kinesin-8 family of microtubule motors, which are required for microtubule–cortical interactions, normal spindle assembly and kinetochore… Expand
