Abstract
Current colorectal cancer mouse models either lack colon specificity, limiting progression towards more advanced disease, or preclude evaluation of resident stem cells as cancer origins. Here we report the identification of NOX1 and NPY1R as cell-surface markers enriched in LGR5+ stem cells predominantly within the caecum and exclusively within the middle and distal colorectum, respectively. Selective dysregulation of Wnt signalling in NOX1+ or NPY1R+ stem cells using CreERT2 mouse lines drives colon cancer initiation, predominantly within the caecum and rectum respectively, establishing these stem cell populations as important sources of colon cancer. Selective conditional activation of Wnt signalling and oncogenic Kras in combination with loss of TRP53 in these stem cell compartments resulted in the development of advanced, invasive cancers. This study establishes CreERT2 drivers as valuable tools for studying stem cell contributions to colon cancer. Gasnier et al. identify NOX1 and NPY1R as markers of colon stem cells within the mouse caecum and the middle and distal colorectum, respectively. These stem cells contribute to the initiation of invasive colon tumours in mice.
