چکیده انگلیسی
Radiation induced genomic instability can be perpetuated over time by the transmission of soluble factors. This can occur via cell-to-cell gap junction communication or the secretion/shedding of soluble factors. We have investigated whether our radiation induced chromosomally unstable GM10115 human-hamster hybrid clones secrete factors that can perpetuate the instability phenotype over time. These clones do not have functional gap junctions, but do secrete significant amounts of Interleukin 8 (IL-8) into the culture medium. We then determined whether IL-8 could initiate and or perpetuate genomic instability over time in parental GM10115 cells. Contrary to our hypothesis, IL-8 could induce DNA damage, but was not responsible for the unstable phenotype. Instead it appears that IL-8 secretion provides a pro-survival function in cells that are chromosomally unstable and generally fail to thrive.
