High Fat Diets and Colorectal Cancer

In a recent study featured in Science Daily, "poor diet is associated with 80% of colorectal cancer cases, but the exact pathways by which diet leads to cancer are not known."

Research from the Cleveland Clinic have identified a specific molecular pathway that links high-fat diets and tumor growth in the colon.  

"In the July 6 issue of Stem Cell Reports, the team showed in pre-clinical models that cancer stem cell growth in the colon was enhanced by a high-fat, Western diet. Cancer stem cells are a subset of resilient, aggressive malignant cells that are believed to be partially responsible for spread and recurrence of cancer.
Furthermore, when the researchers blocked the JAK2-STAT3 cellular signaling pathway, a widely studied pathway known to promote tumor growth, the spike in cancer stem cell growth caused by the high-fat diet declined.
This study provides more insight into how the JAK2-STAT3 pathway is linked to diet-related cancer. Pinpointing the exact mechanism can help researchers develop therapeutics to counteract the negative effects of a Western diet on colorectal cancer" (Science Daily).
