flag High-fat diets reprogram liver cells, increasing cancer risk, a new MIT study finds.

flag A new MIT study finds that long-term high-fat diets reprogram liver cells into a primitive, stem-like state, increasing liver cancer risk. flag Chronic metabolic stress from fat overload causes cells to abandon normal functions like metabolism and protein production, instead activating survival mechanisms that make them more vulnerable to cancer-causing mutations. flag Using single-cell RNA sequencing in mice, researchers observed that nearly all high-fat diet-fed mice developed liver cancer, with key transcription factors identified as potential therapeutic targets. flag The findings explain why fatty liver disease often precedes liver cancer and highlight the profound, lasting biological changes caused by poor diet.
