Nucleolar stress with and without p53
Webstress inhibitors did not affect basal Eot3 intracellular concentration or secretion. PERKi caused an 18% reduction in intracellular Eot3 and 30% reduction in IL13-induced Eot3 secretion. Conversely, IRE1i and Sal both increased IL13-induced Eot3 secretion, 1.95- and 1.53-fold, respectively, without altering intracellular levels.
