Abstract

Cell motility plays important physiological roles in embryogenesis. immune defense. wound healing. and metastasis of tumor cells. Cell motility of normal cells is tightly regulated. while tumor cell motility is aberrantly regulated or autoregulated. Autotaxin (ATX) is a 125-kDa glycoprotein. originally isolated from the conditioned medium of human melanoma A2058 cells. ATX stimulates random (chemokinetic) and directed (chemotactic) motility of human tumor cells at high picomolar to low nanomolar concentrations. (omitted)
