819-Epigenetic Memory of Colitis Promotes Tumour Growth
This study investigates the epigenetic memory that remains in colonic stem cells long after inflammation from colitis has resolved. Researchers discovered that even when the tissue appears physically healed, stem cells retain a "memory" of the injury through lasting changes in chromatin accessibility and DNA methylation. This process is driven primarily by the AP-1 transcription factor, which stays active and is passed down through clonal lineages as cells divide. Crucially, this molecular memory primes stem cells for faster tumor growth when oncogenic mutations occur, providing a clear…
