Resolving genetic heterogeneity in cancer.
(NATURE PUBLISHING GROUP, 2019-07-01)
To a large extent, cancer conforms to evolutionary rules defined by the rates at which clones mutate, adapt and grow. Next-generation sequencing has provided a snapshot of the genetic landscape of most cancer types, and ...
Spatially constrained tumour growth affects the patterns of clonal selection and neutral drift in cancer genomic data.
(PUBLIC LIBRARY SCIENCE, 2019-07-29)
Quantification of the effect of spatial tumour sampling on the patterns of mutations detected in next-generation sequencing data is largely lacking. Here we use a spatial stochastic cellular automaton model of tumour growth ...
Measuring Clonal Evolution in Cancer with Genomics.
(ANNUAL REVIEWS, 2019-08-31)
Cancers originate from somatic cells in the human body that have accumulated genetic alterations. These mutations modify the phenotype of the cells, allowing them to escape the homeostatic regulation that maintains normal ...
Subclonal reconstruction of tumors by using machine learning and population genetics.
(NATURE PUBLISHING GROUP, 2020-09-01)
Most cancer genomic data are generated from bulk samples composed of mixtures of cancer subpopulations, as well as normal cells. Subclonal reconstruction methods based on machine learning aim to separate those subpopulations ...
Evolutionary dynamics of neoantigens in growing tumors.
(NATURE PORTFOLIO, 2020-10-01)
Cancers accumulate mutations that lead to neoantigens, novel peptides that elicit an immune response, and consequently undergo evolutionary selection. Here we establish how negative selection shapes the clonality of ...
Clinical trial designs for evaluating and exploiting cancer evolution.
(ELSEVIER SCI LTD, 2023-07-01)
The evolution of drug-resistant cell subpopulations causes cancer treatment failure. Current preclinical evidence shows that it is possible to model herding of clonal evolution and collateral sensitivity where an initial ...
First passage time analysis of spatial mutation patterns reveals sub-clonal evolutionary dynamics in colorectal cancer.
(PUBLIC LIBRARY SCIENCE, 2023-03-01)
The signature of early cancer dynamics on the spatial arrangement of tumour cells is poorly understood, and yet could encode information about how sub-clones grew within the expanding tumour. Novel methods of quantifying ...
Robust RNA-based in situ mutation detection delineates colorectal cancer subclonal evolution.
(NATURE PUBLISHING GROUP, 2017-12-08)
Intra-tumor heterogeneity (ITH) is a major underlying cause of therapy resistance and disease recurrence, and is a read-out of tumor growth. Current genetic ITH analysis methods do not preserve spatial context and may not ...
