1. A general deterministic framework for modeling chromosome missegregations
   The Mathematical Oncology Blog: Behind the Paper
   Noemi Andor: “Modeling mis-segregations is hard because of the sheer number of possible karyotypes. More than 70 quintillions (considering 8 states/chr)! We derived a deterministic framework for modeling mis-segregations (MS) of multiple chromosome types accounting for viable karyotype intervals of all 22 autosomes simultaneously and for the turnover rate of the population. It offers the flexibility to identify potential synergies between copy number changes of multiple chromosomes and to model intra-tumor heterogeneity in the copy number of all chromosomes, as well as karyotype specific MS- and turnover rates.“

The newsletter now has a dedicated homepage where we post the cover artwork for each issue. We encourage submissions that coincide with the release of a recent paper from your group. This week’s artwork:

Based on the paper: “Somatic mutation rates scale with lifespan across mammals” in Nature.

Artist: Alex Cagan (@ATJCagan)

Caption: "Somatic mutations drive cancer and may play a role in ageing. Across the tree of life there is great diversity in cancer risk and the speed at which species age, yet we know very little about somatic mutational processes in non-human species. This illustration highlights the 16 species of mammals that we studied to compare their somatic mutation rates and signatures. The pointillist style was chosen to echo the process of somatic mutation and clonal expansion that is presumably occurring within the tissues of all mammals as they age but which has hitherto been invisible to us. The double-helix hourglass references the accumulation of mutations over time and speculates on the potential relationship between genome integrity and ageing."
