Preface

The chemokine receptors are a diverse family of seven-transmembrane G-protein-coupled receptors binding a large family of ligands. Chemokine receptors were first identified on leukocytes and mediate directed migration of many host cells to sites of ligand expression. It is now well established that most malignant cells also express one or more chemokine receptor. This volume will summarize the growing body of evidence that several chemokine receptors contribute to tumor behavior. There is abundant evidence that CXCR4, which is widely expressed in many malignancies, contributes to the ability of tumor cells to metastasize to sites of ligand expression. Evidence for regulation of CXCR4 by hypoxia is described. Like CXCR4, both CCR7 and CXCR3 function to promote tumor cell homing and metastasis of melanoma, breast and colon cancers. Several chemokine receptors also function to support the survival and proliferation of tumor cells either directly or through transactivation by tyrosine kinase-coupled growth factor receptors. While chemokine receptors expressed on tumor cells generally support tumor growth and dissemination, expression of these receptors on host cells has both pro-tumor and anti-tumor functions. Both angiostatic and angiogeneic functions of CXC chem
