Abstract

Invasive and metastatic activities are the most challenging hallmark of cancer. We previously showed that GEP100-Arf6 pathway signals from stimulated ErbB family receptors was pivotal for epithelio-mesenchymal transition (EMT) and induced cancer invasive activity leading to nodal and distant metastasis. Here we have examined the enhancing effect of Grb2 on the binding of GEP100 with EGFR leading to Arf6 activation and EMT, and the significance of EGFR-Grb2-GEP100 binding complex on the invasive and metastatic potentials in lung cancer cells as well as in clinical settings.
