Actomyosin drives cancer cell nuclear dysmorphia and threatens genome stability

open access: yesNature Communications, 2017
Recent findings suggest that forces acting on the cell nucleus can cause DNA damage, but the mechanisms are unclear. Here Takakiet al. report that actomyosin is a determinant of nuclear shape and that unrestrained contractility elicits nuclear envelope ...

Modulation of Aneuploidy in Leishmania donovani during Adaptation to Different In Vitro and In Vivo Environments and Its Impact on Gene Expression

open access: yesmBio, 2017
Aneuploidy is usually deleterious in multicellular organisms but appears to be tolerated and potentially beneficial in unicellular organisms, including pathogens. Leishmania, a major protozoan parasite, is emerging as a new model for aneuploidy, since in

Aneuploidy in the normal, Alzheimer's disease and ataxia-telangiectasia brain: Differential expression and pathological meaning

open access: yesNeurobiology of Disease, 2009
Recently it has been suggested that the human brain contains aneuploid cells; however the nature and magnitude of neural aneuploidy in health and disease remain obscure. Here, we have monitored aneuploidy in the cerebral cortex of the normal, Alzheimer's

Aneuploidy facilitates dysplastic and tumorigenic phenotypes in the Drosophila gut

open access: yesBiology Open, 2021
Aneuploidy has been strongly linked to cancer development, and published evidence has suggested that aneuploidy can have an oncogenic or a tumor suppressor role depending on the tissue context.

Thoughts on Aneuploidy [PDF]

open access: yesCold Spring Harbor Symposia on Quantitative Biology, 2010
Aneuploidy refers to karyotypic abnormalities characterized by gain or loss of individual chromosomes. This condition is associated with disease and death in all organisms in which it has been studied. We have characterized the effects of aneuploidy on yeast and primary mouse cells and found it to be detrimental at the cellular level.

Molecular signatures of aneuploidy-driven adaptive evolution

open access: yesNature Communications, 2020
Aneuploidy (abnormal chromosome number) can enable rapid adaptation to stress conditions, but it also entails fitness costs from gene imbalance. Here, the authors experimentally evolve yeast while forcing maintenance of aneuploidy to identify the ...

Selfish centromeres and the wastefulness of human reproduction.

open access: yesPLoS Biology, 2022
Many human embryos die in utero owing to an excess or deficit of chromosomes, a phenomenon known as aneuploidy; this is largely a consequence of nondisjunction during maternal meiosis I.

Chromosomal Instability, Aneuploidy, and Gene Mutations in Human Sporadic Colorectal Adenomas

open access: yesCellular Oncology, 2004
Whether in vivo specific gene mutations lead to chromosomal instability (CIN) and aneuploidy or viceversa is so far not proven. We hypothesized that aneuploidy among human sporadic colorectal adenomas and KRAS2 and APC mutations were not independent ...

Aneuploidy and confined chromosomal mosaicism in the developing human brain. [PDF]

open access: yesPLoS ONE, 2007
BACKGROUND: Understanding the mechanisms underlying generation of neuronal variability and complexity remains the central challenge for neuroscience.

Induced aneuploidy in neural stem cells triggers a delayed stress response and impairs adult life span in flies.

open access: yesPLoS Biology, 2019
Studying aneuploidy during organism development has strong limitations because chronic mitotic perturbations used to generate aneuploidy usually result in lethality.
