Broken p53 Genes Fuel Ulcerative Colitis Progression to Cancer

A groundbreaking study has linked dysfunctional p53 genes to the advancement of ulcerative colitis (UC) towards cancer. Researchers at the Max Delbrück Center and Charité – Universitätsmedizin Berlin, led by graduate student Kimberly Hartl, pinpoint this gene as a potential new target for therapies aimed at preventing UC from developing into a more dangerous condition.

Chronic Repair Mode Drives Disease Progression

Findings published in Science Advances reveal that in UC patients, intestinal cells become stuck in a perpetual “repair” mode, overproducing and malfunctioning. This aberrant behavior stems from a faulty p53 gene, a key tumor suppressor that normally keeps cellular growth in check.

“By targeting these aberrant cells early on, we could potentially prevent the development of cancer in high-risk UC patients,” explained Professor Michael Sigal, a senior author of the study.

Metabolic Imbalance Tied to p53 Dysfunction

To better understand this mechanism, the researchers used a 3D organoid model of the colon. They discovered that cells missing p53 exhibited abnormally high glucose metabolism via glycolysis, keeping them perpetually in a proliferative state. In contrast, active p53 suppresses glucose metabolism, enabling cells to return to a healthy state.

Targeting Metabolic Pathway for Treatment

Leveraging this knowledge, the researchers identified compounds that selectively eliminate p53-deficient cells by targeting glycolysis. This approach holds immense potential for developing novel therapies to pinpoint and eradicate precancerous cells in UC patients.

“By selectively eliminating these cells, we could potentially reduce the risk of cancer development in UC patients,” said Sigal.

Moving towards Clinical Applications

The research team is now focused on translating these findings into tangible clinical applications. They aim to develop simple methods for identifying cells with defective p53 genes in colon tissue, enabling earlier detection and intervention.
