Loss of cadherin 17 downregulates LGR5 expression, stem cell properties and drug resistance in metastatic colorectal cancer cells.

ABSTRACT: Cadherin 17 (CDH17) plays a crucial role in the metastatic progression of colorectal cancer (CRC) through its interaction with α2β1 integrin and desmocollin 1. To further elucidate the molecular mechanisms involving CDH17 functions in CRC, we examined global expression alterations following CDH17 silencing in various metastatic cell lines. Loss of CDH17 resulted in a marked down-regulation of the intestinal cancer stem cell (CSC) marker LGR5, leading to the inhibition of Wnt/β-catenin signaling, suppression of pluripotency genes such as MYC, and a subsequent reduction in stemness properties. Treatment with CDH17/integrin blocking antibodies produced similar effects, decreasing both, LGR5 expression and Wnt signaling. CDH17 silencing also down-regulated various transporters associated with
