Evaluation of Radiodynamic Therapy Using 5-Aminolevulinic Acid in Malignant Lymphoma Cell Lines under Hypoxic Culture Conditions

Key Points

• The research investigates the effects of 5-aminolevulinic acid on malignant lymphoma cell lines under different oxygen conditions.
• Cultured malignant lymphoma cell lines (Raji, HKBML, TK) under normal and hypoxic conditions.
• Analyzed protoporphyrin IX accumulation following 5-ALA treatment.
• Assessed the effectiveness of radiodynamic therapy on cell survival.
• Observed changes in reactive oxygen species production post-radiation.
• Protoporphyrin IX accumulated in all cell lines after 5-ALA treatment.
• 5-ALA/RDT decreased cell survival regardless of oxygen levels.
• Increased delayed reactive oxygen species production observed, especially in Raji cells.
• 5-ALA/RDT may overcome radiation resistance in hypoxic environments.
