Measuring single cell divisions in human tissues from multi-region sequencing data.
(NATURE PUBLISHING GROUP, 2020-02-25)
Both normal tissue development and cancer growth are driven by a branching process of cell division and mutation accumulation that leads to intra-tissue genetic heterogeneity. However, quantifying somatic evolution in ...
Quantification of subclonal selection in cancer from bulk sequencing data.
(NATURE PUBLISHING GROUP, 2018-05-28)
Subclonal architectures are prevalent across cancer types. However, the temporal evolutionary dynamics that produce tumor subclones remain unknown. Here we measure clone dynamics in human cancers by using computational ...
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 ...
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 ...
The mutational signatures of formalin fixation on the human genome.
(NATURE PORTFOLIO, 2022-09-06)
Clinical archives of patient material near-exclusively consist of formalin-fixed and paraffin-embedded (FFPE) blocks. The ability to precisely characterise mutational signatures from FFPE-derived DNA has tremendous ...
Immune selection determines tumor antigenicity and influences response to checkpoint inhibitors.
(NATURE PORTFOLIO, 2023-03-01)
In cancer, evolutionary forces select for clones that evade the immune system. Here we analyzed >10,000 primary tumors and 356 immune-checkpoint-treated metastases using immune dN/dS, the ratio of nonsynonymous to synonymous ...
Classifying the evolutionary and ecological features of neoplasms.
(NATURE PUBLISHING GROUP, 2017-10-01)
Neoplasms change over time through a process of cell-level evolution, driven by genetic and epigenetic alterations. However, the ecology of the microenvironment of a neoplastic cell determines which changes provide adaptive ...
Cancer associated fibroblast FAK regulates malignant cell metabolism.
(NATURE PUBLISHING GROUP, 2020-03-10)
Emerging evidence suggests that cancer cell metabolism can be regulated by cancer-associated fibroblasts (CAFs), but the mechanisms are poorly defined. Here we show that CAFs regulate malignant cell metabolism through ...
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 ...
Immunosuppressive niche engineering at the onset of human colorectal cancer.
(NATURE PORTFOLIO, 2022-04-04)
The evolutionary dynamics of tumor initiation remain undetermined, and the interplay between neoplastic cells and the immune system is hypothesized to be critical in transformation. Colorectal cancer (CRC) presents a unique ...
