Cancer development and progression result from somatic evolution by an
accumulation of genomic alterations. The effects of those alterations on the
fitness of somatic cells lead to evolutionary adaptations such as increased cell
proliferation, angiogenesis, and altered anticancer drug responses. However,
there are few general mathematical models to quantitatively examine how
perturbations of a single gene shape subsequent evolution of the cancer genome.
In this study, we proposed the gene gravity model to study the evolution of
cancer genomes by incorporating the genome-wide transcription and somatic
mutation profiles of ~3,000 tumors across 9 cancer types from The Cancer Genome
Atlas into a broad gene network. We found that somatic mutations of a cancer
driver gene may drive cancer genome evolution by inducing mutations in other
genes. This functional consequence is often generated by the combined effect of
genetic and epigenetic (e.g., chromatin regulation) alterations. By quantifying
cancer genome evolution using the gene gravity model, we identified six putative
cancer genes (AHNAK, COL11A1, DDX3X, FAT4, STAG2, and SYNE1). The tumor genomes
harboring the nonsynonymous somatic mutations in these genes had a higher
mutation density at the genome level compared to the wild-type groups.
Furthermore, we provided statistical evidence that hypermutation of cancer driver
genes on inactive X chromosomes is a general feature in female cancer genomes. In
summary, this study sheds light on the functional consequences and evolutionary
characteristics of somatic mutations during tumorigenesis by propelling adaptive
cancer genome evolution, which would provide new perspectives for cancer research
and therapeutics.
