Radiation-induced Cell Death and Its Mechanisms

Area of Science:

• Cell Biology
• Radiation Oncology
• Molecular Mechanisms

Background:

• Ionizing radiation is increasingly used in daily life and medicine.
• Cell death is a primary cytological effect of ionizing radiation.
• Classifying radiation-induced cell death is complex due to molecular diversity.

Purpose of the Study:

• To review the classifications of radiation-induced cell death.
• To elucidate the molecular mechanisms underlying these death pathways.
• To examine the characteristics of ionizing radiation-induced cell death.

Main Methods:

• Literature review focusing on radiation-induced cell death.
• Analysis of molecular mechanisms and classifications.
• Examination of cell death characteristics under varying radiation doses and environments.

Main Results:

• Radiation-induced cell death modes include apoptosis, necrosis, autophagy-dependent cell death, pyroptosis, ferroptosis, and immunogenic cell death.
• High-dose radiation can cause non-specific cellular destruction.
• Classification is challenging due to diverse cell phenotypes, cell cycle phases, radiation doses, and signaling molecule crosstalk.

Conclusions:

• Understanding diverse radiation-induced cell death pathways is vital for radiation injury management and radiotherapy.
• Further research is needed to clarify the complex molecular mechanisms and classification challenges.
• Accurate classification aids in developing targeted protective and therapeutic strategies against radiation effects.
