The Influence of High-Fat Diet in Early Life on Intestinal Tumorigenesis in APC1638N Mice

Objectives Colorectal cancer (CRC) is one of the most prevalent cancer worldwide. Evidence from epidemiological studies shows that the incidence rate of CRC among elders with age ≥ 50 years is gradually decreased, whereas the rate continuously rise in adults with age < 50 years. Along with the rise of CRC in young adults, a significantly increasing trend in obesity is also observed in youth. The present study aims to investigate how the early-life nutrition influences the intestinal tumorigenesis later in mouse with an age equivalent to an age < 50 years in human.
