Background: The use of nanomaterial-based radiosensitizers to improve the therapeutic ratio has gained attraction in radiotherapy. Increased radiotoxicity applied to the tumor region may result in an adverse impact on the unexposed normal cells to the radiation, a phenomenon known as Radiation-Induced Bystander Effect (RIBE). Objective: This study aimed to investigate the effect of Bi2S3@BSA Nanoparticles (NPs) as radiosensitizers on the enhancement of bystander response in non-irradiated cells. Methods: Lung carcinoma epithelial cells were exposed to 6 MV x-ray photons at different doses of 2 and 8 Gy, with and without Bi2S3@BSA NPs. The Irradiated Cells Conditioned Medium (ICCM) was collected and incubated with MCR-5 human fetal lung fibroblasts. Results: This study showed that ICCM collec.. Read More»
