Abstract Selenium nanoparticles (SeNPs) were synthesized by irradiating a solution containing sodium selenite (Se+4) as the precursor in YPG liquid medium with gamma-rays. Spherical particles were formed after reactions of sodium selenite with hydrated electrons (eaq-) and hydrogen radicals (H•) produced following water radiolysis. No hazardous reducing agents were employed. The obtained nanoparticles were morphologically characterized, and their physicochemical and structural parameters were analyzed. SeNPs characterization showed all selenium in the Se0 state. We incubated Saccharomyces cerevisiae cells with the SeNPs for 24 h and then challenged the cells with ionizing radiation. After radiation exposure, cells were assessed for cell viability, lipid peroxidation, protein carbonylation, free radical generation, and total sulfhydryl content. The synthesized SeNPs were considered safe and less toxic at the concentration employed than the same selenite concentration. Except for the protein carbonylation results, there were no other significant modifications in viability or the oxidative stress parameters in SeNP-treated cells. It was concluded that 1 mM of the synthesized SeNPs does not trigger oxidative stress. Furthermore, we verified that SeNPs attenuate the reactive oxygen species generation after in vitro ionizing radiation exposure. These observations open up tremendous possibilities for radiosensitizer development.

Aim: Selenium nanoparticles (SeNPs) may have a potential role in treating dermal disorders due to its wide therapeutic properties, but there is a need to evaluate its toxicity in keratinocytes. The present study evaluated the molecular mechanism and mode of cell death induced by SeNPs on dermal keratinocytes. Materials & methods: SeNPs were synthesized, characterized and studied in human keratinocytes cells. Oxidative stress and mitochondrial membrane depolarization were evaluated by various techniques. Additionally, autophagy mediated apoptotic cell death was evaluated. Results: SeNPs induced oxidative stress and apoptotic cell death in keratinocytes by increasing autophagy through the formation of acidic lysosomes and autophagosomes. Conclusion: Overall, SeNPs induce the oxidative stress and autophagy mediated apoptotic cell death in human keratinocytes cells.
