Epigenetic memory of inflammation as a driver of cancer risk: insights from Colitis

Chronic inflammation increases cancer risk, yet the mechanisms linking transient injury to long-term susceptibility remain elusive. Nagaraja et al [1] demonstrate that intestinal stem cells retain durable epigenetic memory of colitis, thereby priming tumorigenesis. This discovery reframes cancer initiation as a consequence of heritable chromatin states, introducing an additional regulatory dimension that operates alongside, and beyond, genetic aberrations. By positioning inflammation induced epigenetic memory as a novel axis for cancer predisposition, this study open avenues for biomarker development and preventive therapeutic strategies.
