“…Natural anticancer agents from plants such as Oroxylum indicum (OI) plant extract, curcumin, usnic acid, and Dictyota dichotoma brown alga extract are discovered to have radiosensitizing or radioprotective properties towards ionizing radiations. [24][25][26][27][28][29] Previously, Rahman et al have indicated that OI leaves extract could enhance the radiation dose of 6 MV and 10 MV photon beams on HeLa cancer cells. 30 The OI leaves extract provides a newly isolated baicalein-rich fraction (BRF) that has been validated to have anti-cancer, anti-virus and anti-oxidant properties.…”

This study aimed to quantify synergetic effects induced by bismuth oxide nanoparticles (BiONPs), cisplatin (Cis) and baicalein-rich fraction (BRF) natural-based agent on the reactive oxygen species (ROS) generation and radiosensitization effects under irradiation of clinical radiotherapy beams of photon, electron and HDR-brachytherapy. The combined therapeutic responses of each compound and clinical radiotherapy beam were evaluated on breast cancer and normal fibroblast cell line. Methods: In this study, individual BiONPs, Cis, and BRF, as well as combinations of BiONPs-Cis (BC), BiONPs-BRF (BB) and BiONPs-Cis-BRF (BCB) were treated to the cells before irradiation using HDR brachytherapy with 0.38 MeV iridium-192 source, 6 MV photon beam and 6 MeV electron beam. The individual or synergetic effects from the application of the treatment components during the radiotherapy were elucidated by quantifying the ROS generation and radiosensitization effects on MCF-7 and MDA-MB-231 breast cancer cell lines as well as NIH/3T3 normal cell line. Results: The ROS generated in the presence of Cis stimulated the most substantial amount of ROS compared to the BiONPs and BRF. Meanwhile, the combination of the components had induced the higher ROS levels for photon beam than the brachytherapy and electron beam. The highest ROS enhancement relative to the control is attributable to the presence of BC combination in MDA-MB-231 cells, in comparison to the BB and BCB combinations. The radiosensitization effects which were quantified using the sensitization enhancement ratio (SER) indicate the highest value by BC in MCF-7 cells, followed by BCB and BB treatment. The radiosensitization effects are found to be more prominent for brachytherapy in comparison to photon and electron beam. Conclusion: The BiONPs, Cis and BRF are the potential radiosensitizers that could improve the efficiency of radiotherapy to eradicate the cancer cells. The combination of these potent radiosensitizers might produce multiple effects when applied in radiotherapy. The BC combination is found to have the highest SER, followed by the BCB combination. This study is also the first to investigate the effect of BRF in combination with BiONPs (BB) and BC (BCB) treatments.

Apigenin, a dietary flavonoid, has gained increasing attention for its potential therapeutic applications in radiation protection and radiosensitization. Ionizing radiation (IR) can harm healthy cells, but as radiotherapy remains crucial in cancer treatment. Owing to the remarkable application of radiotherapy in the treatment of cancers, it is vital to protect healthy cells from radiation hazards while increasing the sensitivity of cancer cells to radiation. This article reviews the current understanding of apigenin's radioprotective and radiosensitive properties with a focuses on the involved signaling pathways and key molecular targets. When exposed to irradiation, apigenin reduces inflammation via cyclooxygenase‐2 inhibition and modulates proapoptotic and antiapoptotic biomarkers. Apigenin's radical scavenging abilities and antioxidant enhancement mitigate oxidative DNA damage. It inhibits radiation‐induced mammalian target of rapamycin activation, vascular endothelial growth factor (VEGF), matrix metalloproteinase‐2 (MMP), and STAT3 expression, while promoting AMPK, autophagy, and apoptosis, suggesting potential in cancer prevention. As a radiosensitizer, apigenin inhibits tumor growth by inducing apoptosis, suppressing VEGF‐C, tumor necrosis factor alpha, and STAT3, reducing MMP‐2/9 activity, and inhibiting cancer cell glucose uptake. Cellular and animal studies support apigenin's radioprotective and anticancer potential, making it a potential candidate for further research. Investigation into apigenin's therapeutic efficacy in diverse cancer types and radiation damage is essential.

High‐energy ionizing radiation (HEIR) can be a powerful tool for wastewater treatment and material synthesis in industry owing to its strong ionization ability. However, deficiencies in research data have limited the further use of the HEIR method. This review discusses the research data accumulated within the past 10 years for the application of gamma irradiation, X‐rays, and ion and electron beams. Each section contains a discussion on the effective HEIR doses and possible available mechanisms. This article reviews the most recent information and highlights issues for future investigation, for the purpose of promoting the full use of HEIR technology in industry.
