Thymosin ß4 (Tß4) is a 43-amino-acid peptide involved in many biological processes. However, the precise molecular signaling mechanism(s) of Tß4 in cell invasion and migration remain unclear. In this study, we show that Tß4 was significantly overexpressed in colorectal cancer tissues compared to adjacent normal tissues and high levels of Tß4 were correlated with stage of colorectal cancer, and that Tß4 expression was associated with morphogenesis and EMT. Tß4-upregulated cancer cells showed increased adhesion, invasion and migration activity, whereas Tß4-downregulated cells showed decreased activities. We also demonstrated that Tß4 interacts with ILK, which promoted the phosphorylation and activation of AKT, the phosphorylation and inactivation of GSK3ß, the expression and nuclear localization of ß-catenin, and integrin receptor activation. These results suggest that Tß4 is an important regulator of the ILK/AKT/ß-catenin/Integrin signaling cascade to induce cell invasion and migration in colorectal cancer cells, and is a potential target for cancer treatment.
