Abstract 2521: Patient GBM cell originated secretome analysis identifies cytokine A, as a potent therapeutic target

Abstract GBM is the most aggressive human primary brain tumor and leads to poor clinical outcomes. According to previous studies, exogenous factors secreted from primary brain tumor cells can change the growth pattern of normal cells. We analyzed the ingredients of cell culture media from two patient glioblastoma cells which can grow without growth factors. As a result, we selected a significant factor for tumor cell growth which is called cytokine A, the Heparin-binding growth factor. Because of the cell viability maintenance ability of cytokine A, we tried to investigate detailed mechanism of cytokine A and applied the result to the combination therapy. Cytokine A is critical for tumorigenesis of GBM by modulating DNA damage signaling and cell cycle through ROS. For that reason, cytokine A is effective therapeutic target and can be used in combination therapy.
