G. To evaluate effects of IKBKE/TBK1 inhibition on NF-κB signaling in Ewing, TC32 cells were incubated with CYT387 for six hours prior to stimulation with TNF-α (30 ng/mL). IκBα degradation was measured by harvesting TC32 cells thirty minutes after stimulation with TNF-α. TNF-α stimulation resulted in degradation of IκBα, and this effect was attenuated with CYT387 treatment. Parthenolide, an inhibitor of IκBα phosphorylation was used as a positive control. Similar effects of CYT387 activity were seen in HEK-293T cells which also express IKBKΕ. Nuclear extracts were prepared from TC32 cells harvested following forty-five minutes of TNF-α stimulation. Treatment with CYT387 resulted in decreased nuclear localization of NF-κB family proteins RelA/p65 and c-Rel. There was a modest impairment of p50 nuclear localization as compared to parthenolide and DMSO controls and no change in p52 nuclear localization. RelB (not shown) is not expressed in TC32 cells |
