Genomic instability, an increased rate of genome alterations, is crucial in carcinogenesis. This review covers radiation-induced genomic instability, its causes, epigenetic factors, and delayed effects.

Area of Science:

  • Genetics
  • Radiation Biology
  • Cancer Research

Background:

  • Genomic instability involves increased acquisition of DNA alterations, including mutations and chromosomal abnormalities.
  • This instability is increasingly recognized as a key factor in cancer development and progression.
  • Cellular pathways for DNA replication, repair, and gene expression are vital for maintaining genomic integrity.

Purpose of the Study:

  • To review the current understanding of radiation-induced genomic instability.
  • To discuss factors initiating and perpetuating the unstable phenotype.
  • To explore the role of epigenetics and delayed effects of ionizing radiation.

Main Methods:

  • Literature review of radiation-induced genomic instability.
  • Analysis of events and processes contributing to genomic instability.
Keywords:
Non-programmatic

  • Discussion of epigenetic influences and delayed cellular responses to radiation.

    • Main Results:

    • Genomic instability is a significant hallmark of cancer.
    • Ionizing radiation can induce and perpetuate genomic instability.
    • Epigenetic factors and delayed effects play a role in radiation-induced genomic instability.

    Conclusions:

    • Understanding radiation-induced genomic instability is critical for cancer research.
    • Further investigation into epigenetic modifications and delayed effects is warranted.
    • Genomic instability is a complex phenomenon with implications for cancer therapy and prevention.
