The team, led by graduate student Kimberly Hartl, has discovered that a dysfunctional p53 gene plays a pivotal role in the pathogenesis of UC, promising new avenues for treatment to halt the progression to cancer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.science.org\/doi\/10.1126\/sciadv.adp8783\" title=\"\">Published<\/a> in Science Advances, the study delves into how the p53 gene \u2014 a crucial tumor suppressor \u2014 fails to regulate the cell cycle and DNA repair in UC patients, thereby increasing their cancer risk.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Uncovering the Mechanism<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Ulcerative colitis, which affects around 5 million people worldwide, primarily damages the large intestine, specifically the crypts \u2014 tube-like glands in the epithelial tissue. These crypts house stem cells that are essential for the colon\u2019s health and proper function.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When the colon sustains injury, these epithelial crypt cells enter a repair mode, proliferating rapidly to mend the damage. However, in individuals with UC, this process goes awry, trapping cells in a regenerative state and leading to impaired colon function. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The study sheds light on the p53 gene\u2019s critical role in this mechanism. The colon&#8217;s struggle to function normally in UC triggers a toxic feedback loop of excessive stem cell proliferation. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIf there is no p53, cells remain in a proliferative state,\u201d senior author Michael Sigal, a group leader of the Gastrointestinal Barrier, Regeneration Carcinogenesis lab at MDC-BIMSB and head of Luminal Gastroenterology at Charit\u00e9, said in a <a href=\"https:\/\/www.mdc-berlin.de\/news\/press\/cancer-risk-linked-p53-ulcerative-colitis\" title=\"\">news release<\/a>.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Towards New Diagnostics and Treatments<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Current methods like colonoscopies can spot visible lesions but might miss early, non-visible abnormalities. The findings raise the possibility of developing molecular diagnostic tools to detect and eliminate aberrant cells before cancer develops.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIn patients with ulcerative colitis who are at high risk for developing cancer, we could potentially target aberrant cells and get rid of them early, before any cancer occurs,\u201d Sigal added.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In their study, the team used three-dimensional organoid models of the colon derived from mouse stem cells. These models enabled them to observe that cells lacking functional p53 were stuck in the regenerative state, leading to increased glucose metabolism through glycolysis.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The researchers experimented with glycolysis inhibitors, discovering that p53-deficient cells were more susceptible to these treatments, opening doors to targeted therapeutic interventions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWith organoids, we can identify very specific agents that can target metabolic pathways and point us toward potentially new therapeutics to selectively target mutated cells,\u201d Hartl said in the news release.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Next Steps<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Moving forward, the team plans to apply these findings to human studies. They aim to develop simpler methods to identify cells with defective p53 genes in colon tissue, potentially leading to clinical studies to selectively eliminate these cells and mitigate cancer risk.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cOnce we have a simple method of identifying these individual cells in colon tissues, we could perform clinical studies to selectively kill them and then analyze whether this is associated with a lower risk of developing cancer,\u201d Sigal added.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The implications of this study extend beyond merely understanding UC; they offer a beacon of hope for devising preventive strategies against colon cancer in at-risk populations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A significant breakthrough in understanding the link between ulcerative colitis (UC) and cancer has been made by researchers at the Berlin Institute for Medical Systems Biology of the Max Delbr\u00fcck Center (MDC-BIMSB) and Charit\u00e9 \u2013 Universit\u00e4tsmedizin Berlin.
