Finding NEMO – radiation induced bystander effects elicit (NF-κB) dependent survival

Radiation-induced bystander effects (RIBE) are an acknowledged issue of radiation therapy. Radiation of tumor tissue has been shown to affect non-irradiated neighboring cells in a paracrine and endocrine manner. Transduction of bystander signaling though remains to be investigated in detail. A part of the transduction is the receptor-initiated activation of signaling pathways by secreted factors of the irradiated cell during irradiation damage response. This work focusses on the activation of the transcription factor Nuclear Factor κB (NF-κB) in bystander cells after irradiation.
