CUT&RUN experiment in colon cancer cells (HCT116, DLD1 and SW620), assessing TBX3 genomic occupancy
The Wnt/ß-catenin signaling pathway plays crucial roles in nearly all parts of embryonic development and adult stem cell homeostasis. Its aberrant activation has been linked to many diseases such as developmental irregularities and various severe forms of cancer, with colorectal cancer (CRC) as a prime example. While much work has been dedicated to uncovering effective therapeutics to block oncogenic Wnt signaling, such interventions have not proven trivial because of the broad activity of Wnt throughout the adult body and the difficulty in finding suitable molecular targets. We have previously identified the developmental transcription factor TBX3 as a participant of the Wnt-mediated transcriptional regulation. Here we examine the genome-wide binding pattern of TBX3 in the human CRC cells lines HCT116 (25 replicates), DLD1 (2 replicates) and SW620 (2 replicates), by employing CUT&RUN (C&R) with Low-Volume and Urea (LoV-U; Zambanini et al., 2022).
