Dishevelled-1 regulates global transcriptomic changes in MDA-MB-231 triple negative breast cancer cells (ChIP-Seq).
Dishevelled (DVL) is a crucial component of the Wnt-signaling pathway and is vital for multiple physiological processes. Previously thought to have a primarily cytoplasmic role, the discovery of DVL translocation to the nucleus reframed how DVL is viewed functionally. Despite our advances in elucidating DVL nuclear function, further investigation is needed to determine its transcriptomic and epigenetic regulatory abilities. We show here that modification of DVL1 expression globally affects the transcriptomic landscape. Additionally, analysis of DVL1 ChIP-seq allowed us to map global binding sites and reveal the extensive reach of DVL1 binding sites. Integration of RNA-Sequencing and ChIP-Sequencing further revealed DVL1 transcription factor binding partners to regulate gene expression. These findings provide insight to nuclear DVL1 regulation of gene transcription. Overall design: Chromatin immunoprecipitation DNA-sequencing (ChIP-seq) for DVL1 in triple-negative breast cancer cell line MDA-MB-231.
