P38 activates OTUD7B. 4 / 4
| 1 3

reach
"Here we describe a novel form of cross-talk between the NF-κB and MAP kinase pathways where p38-dependent induction of Cezanne during hypoxia suppresses NF-κB activity."

eidos
"We examined the mechanism of Cezanne induction by p38 , which is known to influence gene expression via members of the activating transcription factor ( ATF ) family and also by enhancing mRNA stability25 ."

reach
"P38 also enhanced the stability of Cezanne transcripts in hypoxic EC as pharmacological inhibition of p38 using SB202190 destabilized Cezanne mRNA in actinomycin D chase experiments (Online Fig. V)."

reach
"Thus we conclude that p38 induces Cezanne through both transcriptional and post-transcriptional mechanisms."
