A Role for Bioelectric Effects in the Induction of Bystander Signals by Ionizing Radiation?

A role for bioelectric effects in the induction of bystander signals by ionizing radiation?

The induction of "bystander effects" i.e. effects in cells which have not received an ionizing radiation track, is now accepted but the mechanisms are not completely clear. Bystander effects following high and low LET radiation exposure are accepted but mechanisms are still not understood. There is some evidence for a physical component to the signal. This paper tests the hypothesis that bioele...

The Role of Target and Bystander Cells in Dose-Response Relationship of Radiation-Induced Bystander Effects in Two Cell Lines

Radiation Bystander Effects Mechanism

  Introduction: Radiation Induced Bystander Effect (RIBE) which cause radiation effects in non-irradiated cells, has challenged the principle according to which radiation traversal through the nucleus of a cell is necessary for producing biological responses. What is the mechanism of this phenomenon? To have a better understanding of this rather ambiguous concept substantial number of original ...

Mutation Induction by Ionizing Radiation

Fluorescence in situ hybridization (FISH) has opened new perspectives for the identification and classification of radiation induced chromosome aberrations. Selective staining of individual human chromosomes by chromosome painting allows a rapid microscopic observation of dicentric and translocation chromosomes. Methods of automated digital image analysis accelerate the evaluation of FISH label...
