Cenp-E inhibitor GSK923295: Novel synthetic route and use as a tool to generate aneuploidy

Aneuploidy is a common feature of cancer, with human solid tumour cells typically harbouring abnormal chromosome complements. The aneuploidy observed in cancer is often caused by a chromosome instability phenotype, resulting in genomic heterogeneity. However, the role aneuploidy and chromosome instability play in tumour evolution and chemotherapy response remains poorly understood. In some cont...

The Role of Chromosome Missegregation in Cancer Development: A Theoretical Approach Using Agent-Based Modelling

Many cancers are aneuploid. However, the precise role that chromosomal instability plays in the development of cancer and in the response of tumours to treatment is still hotly debated. Here, to explore this question from a theoretical standpoint we have developed an agent-based model of tissue homeostasis in which to test the likely effects of whole chromosome mis-segregation during cancer dev...

Examining the link between chromosomal instability and aneuploidy in human cells

Solid tumors can be highly aneuploid and many display high rates of chromosome missegregation in a phenomenon called chromosomal instability (CIN). In principle, aneuploidy is the consequence of CIN, but the relationship between CIN and aneuploidy has not been clearly defined. In this study, we use live cell imaging and clonal cell analyses to evaluate the fidelity of chromosome segregation in ...

Elevated tolerance to aneuploidy in cancer cells: estimating the fitness effects of chromosome number alterations by in silico modelling of somatic genome

An unbalanced chromosome number (aneuploidy) is present in most malignant tumours and has been attributed to mitotic mis-segregation of chromosomes. However, recent studies have shown a relatively high rate of chromosomal missegregation also in non-neoplastic human cells, while the frequency of aneuploid cells remains low throughout life in most normal tissues. This implies that newly formed an...
