Special Issue Information

Dear Colleagues,

We invite you to contribute to this Special Issue on new challenges in radiobiology. The contribution radiobiology has made to the promotion of human health is exemplified by the wealth of knowledge it has generated in cancer radiotherapy (RT), using ever-evolving enhancements from fields such as physics, chemistry, and molecular biology. However, radiobiology is far from having exhausted its propulsive force and still has a fundamental role to play by harnessing technological advances, such as unexplored temporal regimes or artificial intelligence. Moreover, a renewed interest in combined modality treatments, such as BNCT, or the need for a standardised approach—from advanced microdosimetry to Monte Carlo-based simulations—to accurately match physical parameters with biological responses, demands updated radiobiological workflows Finally, topics such as the systemic responses elicited by radiation or 3D/novel in vitro study models (spheroids and organ-on-a-chip technology) all invoke new radiobiological trends.

This Special Issue, “Radiobiology: New Challenges and Advances, will, therefore, focus on this “new radiobiology” and will include original research and provocative review articles.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The fruits of Solanum lycopersicum L. cultivar “Microtom” are a powerful source of antioxidants. We investigated whether two light-quality regimes, i.e., fluorescent white (FL) and red-blue (RB), influenced the antioxidant composition in such fruits, and assessed the potential radioprotective properties of their extracts on normal human cells exposed to clinical photons as used in cancer radiotherapy (RT). Increasing normal-tissue tolerance to radiation is critical for reducing the risk of RT-associated sequelae. Biochemical characterization showed that RB enhanced the content of antioxidant phytochemicals (i.e., polyphenols, flavonoids, total carotenoids, lycopene), while FL promoted ascorbic acid synthesis. Initially tested at 200 µg/mL, RB-derived extracts decreased radiation-induced DNA damage as measured by the cytokinesis-block micronucleus (CBMN) assay in epidermal HaCaT cells. Both RB and FL regimes were subsequently studied in MCF-10A breast cancer (BC) cells, a model of normal-tissue radioresponse in BC RT, using extracts at 100 and 200 µg/mL and also evaluating oxidative stress by a ROS detection assay. Both FL and RB afforded radioprotection. However, RB suppressed radiation-induced MN formation and oxidative stress to a greater extent compared to FL. Therefore, modulation of light-quality regimes represents an innovative approach for developing radionutraceuticals with potential benefits for RT patients. Full article
