Dr. Jabbari is specializing in Medical physics. currently, I am working in field of bystander effect of ionizing radiation in cancer cell biology. Radiation therapy treats many types of cancer effectively. But like other treatments, it often causes side effects.The radiation-induced bystander effect is the phenomenon which non-irradiated cells exhibit effects along with their different levels as a result of signals received from nearby irradiated cells. Responses of non-irradiated cells may include changes in process of translation, gene expression, cell proliferation, and apoptosis and cells death. At this point, our group is going to evaluate the cellular and molecular underling mechanisms governing bystander effects and also pathways deal with tumor relapse and metastasis.
