    Lung cancer
    Selinium nanoparticles (SeNPs) with minimal toxicity and efficient antioxidant properties were reported earlier for their anti-carcinogenic influence against various types of cancers, thus elevating its potential. In the present study, the anti-carcinogenic effect of selenium nanoparticles against lung cancer was studied. Selenium nano-particles were biosynthesized and were characterized using UV- Vis absorption spectroscopy. A decrease in the absorption intensity was recorded with the increase in time, which represented the protein consumption during the reduction of SeO32− to Se0. The calculated average crystalline size from XRD studies of the synthesized selenium nanoparticles was found to be 88.89 nm which was in accordance with the TEM analysis while the SAED pattern has disclosed hexagonal ring structure with diffraction ring pattern.MTT assay was performed to evaluate the radio-sensitizing effect of selenium nanoparticles under the X-ray influence against cancer as well as healthy cell lines. SeNPs showed potent cytotoxicity effect in cancer cells whereas it showed relatively less toxic effect in normal healthy cells. However, caspase-3 activity was even more elevated when subjected to X-ray exposure than in the absence. These findings apparently revealed the cytotoxic potential of SeNPs + X-ray combination in the Ursodeoxycholylglycine lung cancer cell lines.
