In this study the authors show that Rac family small GTPase 1 (RAC1-GTP) is overexpressed in colorectal cancer (CRC) and promotes epithelial-mesenchymal transition-mediated invasion of CRC cells through activation of the STAT3 pathway. Overexpression of RAC1-GTP in CRCs correlates with tumor progression and recurrence of CRCs, and predicts poor prognosis of CRC patients.
