Activation of P-TEFb by cAMP-PKA signaling in autosomal dominant polycystic kidney disease (ChIP-Seq)

We showed that pharmacological inhibition of P-TEFb attenuated cyst development in ADPKD mouse models. Genome-wide analyses demonstrated that P-TEFb inhibition abrogated transcriptional pause release and suppressed a pathologic gene expression program during cystogenesis. This work revealed a mechanism by which aberrant activation of P-TEFb-mediated transcription elongation promotes cystogenesis in ADPKD. We performed ChIP-Seq analysis of RNA Polymerase II in WT, ADPKD and ADPKD mice treated with flavopiridol.
