WebThe mTOR and p53 signaling pathways are connected by a number of different mechanisms. Chemotherapeutics that inhibit ribosome biogenesis often induce nucleolar stress and activation of p53. Here we have investigated how the p53 response to nucleolar stress is affected by simultaneous mTOR inhibition in osteosarcoma and glioma cell lines. WebNational Center for Biotechnology Information

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.
