The genetic basis of aneuploidy tolerance in wild yeast

eLife, 2020
Aneuploidy is highly detrimental during development yet common in cancers and pathogenic fungi – what gives rise to differences in aneuploidy tolerance remains unclear.

Complex interplay between p53 and chromosome stability

Molecular & Cellular Oncology, 2021
TP53-dependent cell cycle arrest has been proposed to limit the proliferation of aneuploid cells. We investigated the cellular response to aneuploidy in cell lines and organoid cultures and found that TP53 (also known as p53) is not activated following ...

Molecular characterization of the A52 murine hepatocellular carcinoma cell line

Animal Models and Experimental Medicine, EarlyView.
Hepatocellular carcinoma (HCC) is a poor outcome cancer with limited therapeutic choices. To advance therapeutic development we genetically characterized the A52 murine HCC cell line. We noted genetic changes that match a subset of human HCC and this offers the opportunity to test novel targeted therapies in syngeneic mice.

Dysregulation of gene expression in the artificial human trisomy cells of chromosome 8 associated with transformed cell phenotypes. [PDF]

PLoS ONE, 2011
A change in chromosome number, known as aneuploidy, is a common characteristic of cancer. Aneuploidy disrupts gene expression in human cancer cells and immortalized human epithelial cells, but not in normal human cells.

Equine models in translational medicine: A comparative approach to human health

Animal Models and Experimental Medicine, EarlyView.
This diagram summarizes and contrasts rodent and equine models, outlining their strengths, limitations, and applications. Horses offer naturally occurring diseases, genetic and physiological similarities to humans, and suitability for longitudinal and clinical‐scale studies.

Machine-learning analysis reveals an important role for negative selection in shaping cancer aneuploidy landscapes

Genome Biology
Background Aneuploidy, an abnormal number of chromosomes within a cell, is a hallmark of cancer. Patterns of aneuploidy differ across cancers, yet are similar in cancers affecting closely related tissues.

The power of many: when genetics met yeasts and high‐throughput

Biological Reviews, EarlyView.
ABSTRACT In recent years, complex technological capabilities have evolved, driven by the need to solve complex and integrative biological questions through global analyses. New equipment allows the scaling up and automation of processes which previously were carried out on a very limited scale.

Clinical and molecular correlates of tumor aneuploidy in metastatic non-small cell lung cancer

Scientific Reports
Recent studies have linked elevated tumor aneuploidy to anti-tumor immune suppression and adverse survival following immunotherapy. Herein, we provide supportive evidence for tumor aneuploidy as a biomarker of response to immunotherapy in patients with ...

Machine Learning Reveals Aneuploidy Characteristics in Cancers: The Impact of BEX4

Frontiers in Bioscience-Landmark
Background: Aneuploidy is crucial yet under-explored in cancer pathogenesis. Specifically, the involvement of brain expressed X-linked gene 4 (BEX4) in microtubule formation has been identified as a potential aneuploidy mechanism ...

The p38α Stress Kinase Suppresses Aneuploidy Tolerance by Inhibiting Hif-1α

Cell Reports, 2018
Summary: Deviating from the normal karyotype dramatically changes gene dosage, in turn decreasing the robustness of biological networks. Consequently, aneuploidy is poorly tolerated by normal somatic cells and acts as a barrier to transformation ...
