  • Publication number: 20230234924
    Abstract: Binding of the transcriptional co-activator, YAP1, to the transcription factor Oct4, induces Sox2, which is a transcription actor necessary for the self-renewal of stem-like cells from non-small cell lung cancer. The WW domain of YAP1 binds to the PPxY motif of Oct4 to induce Sox2. Delivering a peptide corresponding to the WW domain could prevent the induction of Sox2 and sternness. Similarly, peptides and mimetics of the PPxY motif would be able to inhibit sternness. Disclosed are compounds that affect the Yap1:Oct4 interaction.
