Context is everything: aneuploidy in cancer

U Ben-David, A Amon - Nature Reviews Genetics, 2020 - nature.com
Cancer is driven by multiple types of genetic alterations, which range in size from point
mutations to whole-chromosome gains and losses, known as aneuploidy. Chromosome …

Effects of aneuploidy on cell behaviour and function

R Li, J Zhu - Nature Reviews Molecular Cell Biology, 2022 - nature.com
Aneuploidy, a genomic alternation characterized by deviations in the copy number of
chromosomes, affects organisms from early development through to aging. Although it is a …

Stem cell-derived synthetic embryos self-assemble by exploiting cadherin codes and cortical tension

M Bao, J Cornwall-Scoones, E Sanchez-Vasquez… - Nature Cell …, 2022 - nature.com
Mammalian embryos sequentially differentiate into trophectoderm and an inner cell mass,

CDK4/6 inhibitor-mediated cell overgrowth triggers osmotic and replication stress to promote senescence

L Crozier, R Foy, R Adib, A Kar, JA Holt, AU Pareri… - Molecular Cell, 2023 - cell.com

Single-cell analysis of human embryos reveals diverse patterns of aneuploidy and mosaicism

MR Starostik, OA Sosina, RC McCoy - Genome research, 2020 - genome.cshlp.org
Less than half of human zygotes survive to birth, primarily due to aneuploidies of meiotic or
mitotic origin. Mitotic errors generate chromosomal mosaicism, defined by multiple cell …

The correlation between cell and nucleus size is explained by an eukaryotic cell growth model

Y Wu, AF Pegoraro, DA Weitz, P Janmey… - PLoS computational …, 2022 - journals.plos.org
In eukaryotes, the cell volume is observed to be strongly correlated with the nuclear volume.
The slope of this correlation depends on the cell type, growth condition, and the physical …

Antifungal Drug Concentration Impacts the Spectrum of Adaptive Mutations in Candida albicans

RT Todd, N Soisangwan, S Peters… - Molecular biology …, 2023 - academic.oup.com
Invasive fungal infections are a leading global cause of human mortality. Only three major
classes of antifungal drugs are widely used, and resistance to all three classes can arise …

The dynamic fungal genome: polyploidy, aneuploidy and copy number variation in response to stress

P Vande Zande, X Zhou… - Annual review of …, 2023 - annualreviews.org
Fungal species have dynamic genomes and often exhibit genomic plasticity in response to
stress. This genome plasticity often comes with phenotypic consequences that affect fitness …
