Lycopene Ameliorates Ionizing Radiation-Induced Intestinal Injury

Lycopene, a carotenoid known for its potent anti-inflammatory, antioxidant, and immune-modulating properties, is widely utilized in food, nutraceuticals, and medicine. This study aimed to explore the protective and therapeutic effects of lycopene against ionizing radiation-induced intestinal injury. Using a C57BL/6 mouse model exposed to ionizing radiation, we assessed the protective effects of lycopene by analyzing intestinal histology and serological markers. Our findings reveal that ionizing radiation induces oxidative stress, inflammation, and apoptosis in the intestinal epithelium. Lycopene administration effectively mitigated these effects by reducing oxidative stress, decreasing inflammatory responses, and inhibiting apoptosis. Mechanistically, lycopene was found to regulate key metabolic pathways, including linoleic acid and arachidonic acid metabolism, thereby exerting its anti-inflammatory and immune-modulatory effects. These results highlight lycopene's potential as a therapeutic agent for managing radiation-induced intestinal injury, offering a promising strategy for improving the clinical outcomes of patients undergoing radiotherapy.
