“The first thing we noticed was that the small intestine increases greatly in size on the high-calorie diet,” says study leader Anika Böttcher. “Together with Fabian Theis’ team of computational biologists at Helmholtz Munich, we then profiled 27,000 intestinal cells from control diet and high fat/high sugar diet-fed mice. Using new machine learning techniques, we thus found that intestinal stem cells divide and differentiate significantly faster in the mice on an unhealthy diet.” The researchers hypothesize that this is due to an upregulation of the relevant signaling pathways, which is associated with an acceleration of tumor growth in many cancers. “This could be an important link: Diet influences metabolic signaling, which leads to excessive growth of intestinal stem cells and ultimately to an increased risk of gastrointestinal cancer,” says Böttcher.Helmholtz Zentrum München – German Research Center for Environmental Health. “New link between diet, intestinal stem cells and disease discovered.” ScienceDaily. http://www.sciencedaily.com/releases/2021/11/211119155604.htm (accessed November 27, 2021).
I wonder what Dr. Lustig would say about this study?
