In addition, CCKAR knockdown modulated epithelial-mesenchymal transition (EMT) markers ZO-1, E-cadherin, and vimentin and reduced urokinase-type plasminogen activator (uPA), uPA receptor (uPAR), Rho GTPase cell division control protein 42 (CDC42) and RhoA, and matrix metalloproteinase-2 (MMP-2).<h4>Conclusions</h4>These findings indicate that CCKAR knockdown impairs the invasiveness of colon cancer cells, which may be attributed to modulating integrin/FAK/Rho GTPases, EMT markers, and the uPA/uPAR axis. The gene discussed is RHOA; the disease is colonic neoplasm.
