The search for mechanisms underlying different cellular responses to the treatment with Nutlin-3, an MDM2 inhibitor that unleashes p53, revealed a translational control mechanism involving the RNA binding proteins PCBP2 and, particularly, DHX30. Sifting through a multi-functional p53-dependent transcriptional output, this translational control can modulate the activation of cell death pathways.
Keywords: DHX30; PCBP2; apoptosis; p53; polysomal profiling; transcription; translation; translatome.
