    Quantifying chromosomal instability from intratumoral karyotype diversity using agent-based modeling and Bayesian inference

    Andrew R Lynch, Nicholas L Arp ... Mark E Burkard
    Chromosomal instability of cancer can be quantitatively measured by phylogenetic analysis of 200 tumor cells while using evolutionary principles to account for cellular selection.

    High-grade serous ovarian carcinoma organoids as models of chromosomal instability

    Maria Vias, Lena Morrill Gavarró ... James D Brenton
    Fifteen continuous high-grade serous ovarian carcinoma patient-derived organoids are characterized by transcriptomic, genomic, and drug sensitivity assays to reveal that they comprise communities of clonal populations and represent models of different causes of chromosomal instability and degrees of genome complexity.

    Deletion of the MAD2L1 spindle assembly checkpoint gene is tolerated in mouse models of acute T-cell lymphoma and hepatocellular carcinoma

    Floris Foijer, Lee A Albacker ... Peter K Sorger
    Chromosomal instability through spindle assembly checkpoint alleviation facilitates malignant transformation of hepatocytes and T-cells in vivo, resulting in cancers with recurrent karyotypes.

    Chromosome mis-segregation and cytokinesis failure in trisomic human cells

    Joshua M Nicholson, Joana C Macedo ... Daniela Cimini
    Aneuploidy can cause chromosome mis-segregation and specific cellular phenotypes driven by expression of genes on the extra chromosome.

    SPOP mutation leads to genomic instability in prostate cancer

    Gunther Boysen, Christopher E Barbieri ... Mark A Rubin
    SPOP mutations underlie a novel, genomically unstable subclass of prostate cancer by altering DNA repair.

    Catastrophic chromosomal restructuring during genome elimination in plants

    Ek Han Tan, Isabelle M Henry ... Simon WL Chan
    Complex chromosomal rearrangements similar to those described in cancer and developmental syndromes occur in plants during postzygotic genome elimination, a centromeric-derived incompatibility.

    Histone H3G34R mutation causes replication stress, homologous recombination defects and genomic instability in S. pombe

    Rajesh K Yadav, Carolyn M Jablonowski ... Janet F Partridge
    Mutation of Glycine 34 to Arginine within the N-terminal tail of histone H3 alters post-translational modifications on Lysine 36 and is associated with a delay in replication restart, defective homologous recombination and an increase in genomic instability.

    Centrosome age regulates kinetochore–microtubule stability and biases chromosome mis-segregation

    Ivana Gasic, Purnima Nerurkar, Patrick Meraldi
    The presence of cenexin at the old centrosome imposes a functional asymmetry on the mitotic spindle that impacts chromosome alignment and segregation.

    Interrogating the precancerous evolution of pathway dysfunction in lung squamous cell carcinoma using XTABLE

    Matthew Roberts, Julia Ogden ... Carlos Lopez-Garcia
    XTABLE is the first easy-to-use bioinformatic solution that has been conceived and designed solely to interrogate the transcriptomes of premalignant stages of lung squamous cell carcinoma (LUSC) and enhance the development of LUSC prevention and detection strategies.
