Abstract
Perturbations produced by ionizing radiation on intestinal tissue are considered one of highly drastic challenges in radiotherapy. Animals were randomized into five groups. The first group was allocated as control, and the second was subjected to whole body γ-irradiation (10 Gy). The third was administered HA NP (17.6 mg/kg/day; i.p.) and then irradiated. The fourth one received MitoQ (2 mg/kg/day; i.p.) and then irradiated. The last group received MitoQ/HA NP (2 mg/kg/day; i.p.) for 5 days prior to irradiation. Mice were sacrificed a week post-γ-irradiation for evaluation. MitoQ/HA NP ameliorated mitochondrial oxidative stress as indicated by rising (TAC) and glutathione peroxidase and decreasing malondialdehyde, showing its distinguished antioxidant yield. That impacted the attenuation of apoptosis, which was revealed by the restoration of the anti-apoptotic marker and lessening proapoptotic caspase-3. Inflammatory parameters dwindled via treatment with MitoQ/HA NP. Moreover, this new NP exerts its therapeutic action through a distinguished radioprotective pathway (Hmgb1/TLR-4.) Subsequently, these antioxidants and their nanoparticles conferred protection to intestinal tissue as manifested by histopathological examination. These findings would be associated with its eminent antioxidant potential through high mitochondria targeting, enhanced cellular uptake, and ROS scavenging. This research underlines MitoQ/HA NP as a new treatment for the modulation of intestinal damage caused by radiotherapy modalities.

Abstract
Radiotherapy commonly causes damage to healthy tissues, particularly radiation-induced skin injury (RISI) that affects a significant majority of patients undergoing radiotherapy. Effective treatments for RISI are lacking. This study focuses on the pathogenesis of RISI, which primarily involves oxidative stress. Excessive reactive oxygen species (ROS) generation during radiation induces damage to biological macromolecules, triggering oxidative stress and inflammation. To address this, ergothioneine (EGT), a natural and biocompatibile thiol compound with excellent antioxidant activity, is explored as a potential radiation-protective agent. By utilizing its specific transport and absorption in the skin tissue, as well as its efficient and stable clearance of radiation-induced "ROS storm", EGT is combined with sodium hyaluronate (NaHA) to develop a novel radiation protective dressing suitable for the skin. This EGT-NaHA dressing demonstrates an effective ability to scavenge free radicals and reduce oxidative stress in vitro and in vivo, reducing cellular apoptosis and inflammation. These results demonstrate the protective properties of EGT against RISI, with far-reaching implications for research and development in the field of radioprotection.

A Study on the Planarian Model Confirms the Antioxidant Properties of Tameron against X-ray- and Menadione-Induced Oxidative Stress. Antioxidants (Basel) 2023; 12:antiox12040953. [PMID: 37107327 PMCID: PMC10136237 DOI: 10.3390/antiox12040953] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 04/05/2023] [Accepted: 04/14/2023] [Indexed: 04/29/2023] Open
Abstract
Ionizing radiation and radiation-related oxidative stress are two important factors responsible for the death of actively proliferating cells, thus drastically reducing the regeneration capacity of living organisms. Planarian flatworms are freshwater invertebrates that are rich in stem cells called neoblasts and, therefore, present a well-established model for studies on regeneration and the testing of novel antioxidant and radioprotective substances. In this work, we tested an antiviral and antioxidant drug Tameron (Monosodium α-Luminol or 5-amino-2,3-dihydro-1,4-phthalazinedione sodium salt) for its ability to reduce the harm of X-ray- and chemically induced oxidative stress on a planarian model. Our study has revealed the ability of Tameron to effectively protect planarians from oxidative stress while enhancing their regenerative capacity by modulating the expression of neoblast marker genes and NRF-2-controlled oxidative stress response genes.

Mitogen-like Cerium-Based Nanoparticles Protect Schmidtea mediterranea against Severe Doses of X-rays. Int J Mol Sci 2023; 24:ijms24021241.

Abstract
Novel radioprotectors are strongly demanded due to their numerous applications in radiobiology and biomedicine, e.g., for facilitating the remedy after cancer radiotherapy. Currently, cerium-containing nanomaterials are regarded as promising inorganic radioprotectors due to their unrivaled antioxidant activity based on their ability to mimic the action of natural redox enzymes like catalase and superoxide dismutase and to neutralize reactive oxygen species (ROS), which are by far the main damaging factors of ionizing radiation. The freshwater planarian flatworms are considered a promising system for testing new radioprotectors, due to the high regenerative potential of these species and an excessive amount of proliferating stem cells (neoblasts) in their bodies. Using planarian Schmidtea mediterranea, we tested CeO2 nanoparticles, well known for their antioxidant activity, along with much less studied CeF3 nanoparticles, for their radioprotective potential. In addition, both CeO2 and CeF3 nanoparticles improve planarian head blastema regeneration after ionizing irradiation by enhancing blastema growth, increasing the number of mitoses and neoblasts' survival, and modulating the expression of genes responsible for the proliferation and differentiation of neoblasts. The CeO2 nanoparticles' action stems directly from their redox activity as ROS scavengers, while the CeF3 nanoparticles' action is mediated by overexpression of "wound-induced genes" and neoblast- and stem cell-regulating genes.

Antioxidants (Basel) 2021; 10:antiox10111763.

Abstract
Ionising radiation causes the death of the most actively dividing cells, thus leading to depletion of the stem cell pool. Planarians are invertebrate flatworms that are unique in that their stem cells, called neoblasts, constantly replace old, damaged, or dying cells. Amenability to efficient RNAi treatments, the rapid development of clear phenotypes, and sensitivity to ionising radiation, combined with new genomic technologies, make planarians an outstanding tool for the discovery of potential radioprotective agents. In this work, using the well-known antioxidant N-acetylcysteine, planarians are, for the first time, shown to be an excellent model system for the fast and effective screening of novel radioprotective and radio-sensitising substances. In addition, a panel of measurable parameters that can be used for the study of radioprotective effects on this model is suggested.
