Summary
This study investigated genetic mutations in acral melanoma, identifying key genes involved in cell division, adhesion, and metabolism that drive rapid metastasis in this aggressive skin cancer.
Area of Science:
- Oncology
- Genetics
- Dermatology
Background:
- Acral melanoma is an aggressive skin cancer predominantly affecting the palms and feet.
- Understanding its genetic underpinnings is crucial for developing effective treatments.
Purpose of the Study:
- To identify somatic mutations in acral melanoma.
- To pinpoint genes contributing to the rapid metastasis characteristic of this cancer.
Main Methods:
- Massive parallel sequencing of coding regions of 4100 genes.
- Analysis of primary tumors, metastases, and normal tissue from five patients.
Main Results:
- Somatic mutations were identified in genes regulating cell division, proliferation, apoptosis (e.g., BRAF, NRAS), cell adhesion (e.g., CTNND2), angiogenesis (VEGFA), and energy metabolism (BCS1L).
- Comparative analysis highlighted candidate genes associated with rapid metastasis.
Conclusions:
- Specific genetic mutations in acral melanoma are linked to its aggressive nature and metastatic potential.
- These findings provide targets for future therapeutic strategies against acral melanoma.

02:21Cancers Originate from Somatic Mutations in a Single Cell
14.6K
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...

Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

6.4K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

01:09Mutation, Gene Flow, and Genetic Drift
62.5K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).
