APC mutations causing Wnt activation are commonly found in colorectal cancer, but downstream pathways that facilitate tumorigenesis are unclear. In this issue of Cell Stem Cell, Myant et al. (2013) show that Rac1 activation is required for Wnt-driven Lgr5+ intestinal stem cell transformation through ROS production and NF-kB activation.

Abstract
APC mutations causing Wnt activation are commonly found in colorectal cancer, but downstream pathways that facilitate tumorigenesis are unclear. In this issue of Cell Stem Cell, Myant et al. (2013) show that Rac1 activation is required for Wnt-driven Lgr5+ intestinal stem cell transformation through ROS production and NF-kB activation.
