Radiation-induced liver disease (RILD) is a severe radiotherapy side effect. Understanding DNA damage response mechanisms is crucial for preventing RILD and developing targeted treatments for radiation hepatitis.
Area of Science:
- Hepatology
- Radiation Oncology
- Molecular Biology
Background:
- Radiation-induced liver disease (RILD), or radiation hepatitis, is a significant complication of radiotherapy for liver cancer.
- High doses of radiation can damage healthy liver tissue, leading to toxicity and potentially liver fibrosis.
- Current research on RILD mechanisms lags behind other radiation injury studies, with no specific pharmacological treatments available.
Approach:
- This review systematically summarizes the molecular and cellular mechanisms underlying RILD.
- Focuses on the role of the DNA damage response in radiation-induced liver injury.
- Aims to provide a foundation for RILD prevention and treatment strategies.
Key Points:
- Ionizing radiation triggers a DNA damage response that is central to RILD pathogenesis.
- Understanding these molecular and cellular pathways is essential for managing RILD.
- RILD can limit the efficacy of radiotherapy and lead to long-term liver damage.
Conclusions:
- Further research into RILD mechanisms is critical for clinical advancement.
- Developing targeted therapies for RILD is a pressing need in radiation oncology.
- This review provides a comprehensive overview to guide future research and therapeutic development.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
