Molecular signatures of aneuploidy-driven adaptive evolution
Nature 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 ...

Fertility & Reproduction, 2023 Background and Aims: Maternal age has been reported to impact on embryo genetic status. However, current data on the association between maternal age and early embryo development are limited and inconclusive, especially among good-prognosis women.

A systematic approach to cancer: evolution beyond selection. [PDF]
, 2017 Cancer is typically scrutinized as a pathological process characterized by chromosomal aberrations and clonal expansion subject to stochastic Darwinian selection within adaptive cellular ecosystems.

Ectopic expression of human TUBB8 leads to increased aneuploidy in mouse oocytes
Cell Discovery, 2023 Aneuploidy seriously compromises female fertility and increases incidence of birth defects. Rates of aneuploidy in human eggs from even young women are significantly higher than those in other mammals.

Leukemia-related chromosomal loss detected in hematopoietic progenitor cells of benzene-exposed workers. [PDF]
, 2012 Benzene exposure causes acute myeloid leukemia and hematotoxicity, shown as suppression of mature blood and myeloid progenitor cell numbers. As the leukemia-related aneuploidies monosomy 7 and trisomy 8 previously had been detected in the mature ...

Fertility & Reproduction, 2023 Background and Aims: Embryo aneuploidy is caused by many factors, including patient age, sperm quality and sperm selection method. There are several methods for selecting sperm, ICSI (intracytoplasmic sperm injection) and IMSI (intracytoplasmic ...

On the origin of trisomy 21 Down syndrome [PDF]
, 2008 Background: Down syndrome, characterized by an extra chromosome 21 is the most common genetic cause for congenital malformations and learning disability.

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

Selfish centromeres and the wastefulness of human reproduction.
PLoS 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.

Developmental expression of 4-repeat-Tau induces neuronal aneuploidy in Drosophila tauopathy models [PDF]
, 2017 Tau-mediated neurodegeneration in Alzheimer's disease and tauopathies is generally assumed to start in a normally developed brain. However, several lines of evidence suggest that impaired Tau isoform expression during development could affect mitosis and
