Summary
Cancer arises from somatic cell evolution driven by genetic and epigenetic changes. This review explores the evolutionary perspective of cancer genomes, including somatic alterations and contributing factors.
Area of Science:
- Evolutionary biology
- Genomics
- Cancer research
Background:
- Human tumors develop through somatic evolution within tissues.
- Natural selection acts on phenotypic variability from genetic, genomic, and epigenetic alterations.
- Somatic evolution drives adaptations like increased proliferation, angiogenesis, and invasion.
Purpose of the Study:
- To review the investigation of cancer genomes from an evolutionary perspective.
- To highlight progress in cataloging somatic genetic and genomic alterations.
- To examine the roles of germline and epigenetic factors in cancer genome evolution.
Main Methods:
- Review of recent literature on cancer genome evolution.
- Analysis of cataloged somatic genetic and genomic alterations.
- Investigation of germline and epigenetic contributions to cancer evolution.
Main Results:
- Cancer genomes are increasingly studied through an evolutionary lens.
- Significant progress has been made in cataloging somatic alterations.
- Germline and epigenetic factors are recognized as key contributors to cancer genome evolution.
Conclusions:
- Understanding cancer as an evolutionary process is crucial.
- Continued research is needed to fully elucidate the drivers of cancer genome evolution.
- Integrating evolutionary principles offers new insights into cancer development and treatment.

02:21Cancers Originate from Somatic Mutations in a Single Cell
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

02:53Adaptive Mechanisms in Cancer Cells
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
