Neurobiology 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

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.

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 ...

Aneuploidy tolerance caused by BRG1 loss allows chromosome gains and recovery of fitness
Nature Communications, 2022 Aneuploidy results in decreased cellular fitness in many species and model systems. However, aneuploidy is commonly found in cancer cells and often correlates with aggressive growth, suggesting that the impact of aneuploidy on cellular fitness is context

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

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

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 ...

Detection of skewed X-chromosome inactivation in Fragile X syndrome and X chromosome aneuploidy using quantitative melt analysis. [PDF]
, 2015 Methylation of the fragile X mental retardation 1 (FMR1) exon 1/intron 1 boundary positioned fragile X related epigenetic element 2 (FREE2), reveals skewed X-chromosome inactivation (XCI) in fragile X syndrome full mutation (FM: CGG > 200) females ...
