Functional versus non-functional intratumor heterogeneity in cancer.
(2016-07)
Next-generation sequencing data from human cancers are often difficult to interpret within the context of tumor evolution. We developed a mathematical model describing the accumulation of mutations under neutral evolutionary ...
Modeling evolutionary dynamics of epigenetic mutations in hierarchically organized tumors.
(PUBLIC LIBRARY SCIENCE, 2011-05-05)
The cancer stem cell (CSC) concept is a highly debated topic in cancer research. While experimental evidence in favor of the cancer stem cell theory is apparently abundant, the results are often criticized as being difficult ...
A Big Bang model of human colorectal tumor growth.
(NATURE PUBLISHING GROUP, 2015-03-01)
What happens in early, still undetectable human malignancies is unknown because direct observations are impractical. Here we present and validate a 'Big Bang' model, whereby tumors grow predominantly as a single expansion ...
Catch my drift? Making sense of genomic intra-tumour heterogeneity.
(ELSEVIER, 2017-04-01)
The cancer genome is shaped by three components of the evolutionary process: mutation, selection and drift. While many studies have focused on the first two components, the role of drift in cancer evolution has received ...
Measuring cancer evolution from the genome.
(WILEY-BLACKWELL, 2017-01-01)
The temporal dynamics of cancer evolution remain elusive, because it is impractical to longitudinally observe cancers unperturbed by treatment. Consequently, our knowledge of how cancers grow largely derives from inferences ...
Many private mutations originate from the first few divisions of a human colorectal adenoma.
(WILEY, 2015-11-01)
Intratumoural mutational heterogeneity (ITH) or the presence of different private mutations in different parts of the same tumour is commonly observed in human tumours. The mechanisms generating such ITH are uncertain. ...
Identification of neutral tumor evolution across cancer types.
(NATURE PUBLISHING GROUP, 2016-03-01)
Despite extraordinary efforts to profile cancer genomes, interpreting the vast amount of genomic data in the light of cancer evolution remains challenging. Here we demonstrate that neutral tumor evolution results in a ...
Between-region genetic divergence reflects the mode and tempo of tumor evolution.
(NATURE PUBLISHING GROUP, 2017-06-05)
Given the implications of tumor dynamics for precision medicine, there is a need to systematically characterize the mode of evolution across diverse solid tumor types. In particular, methods to infer the role of natural ...
