Celecoxib 55-64 ribosomal protein S6 kinase A3 Homo sapiens 110-113 21044953-3 2010 The current study has revealed a novel ERK/ribosomal S6 kinase (RSK)-dependent mechanism that regulates DR5 expression primarily using celecoxib as a DR5 inducer. Celecoxib 135-144 ribosomal protein S6 kinase A3 Homo sapiens 64-67 21044953-6 2010 Because Elk1 is an ERK-regulated protein, we accordingly found that celecoxib increased the levels of phosphorylated ERK1/2, RSK2, and Elk1. Celecoxib 68-77 ribosomal protein S6 kinase A3 Homo sapiens 125-129 21044953-7 2010 Inhibition of either ERK signaling with a MEK inhibitor or ERK1/2 siRNA, or RSK2 signaling with an RSK2 inhibitor or RSK2 siRNA abrogated DR5 up-regulation by celecoxib as well as other agents.
