Abstract:
:Dietary factors, microbial composition, and metabolism are intimately intertwined into a complex network whose activities influence important intestinal functions. In a recent issue of Cell, Belcheva et al. (2014) show that microbial-derived butyrate promotes proliferation of cancer-initiated intestinal epithelial cells, suggesting that it can act as an oncometabolite.
