Cancer Morbidity and mortality result from invasive and metastatic spread. Currently, no therapies are aimed at the underlying mechanisms that enable this progression due to only nascent recognition of the distinct biology which occurs only during tumor dissemination. Recent advances have highlighted the central role of cell motility during the dynamic and transient process of tumor invasion and metastasis. This book includes state-of-the-art updates by international leaders in these studies. Chapters first present the novel model systems that enable new investigations and insights. Chapters then describe in depth the key processes and molecules that may be therapeutically targeted. Finally, the role of cell motility and its signals is explored in a number of key tumor types. This compilation should be useful to researchers in basic and translational oncology as well as those developing novel agents to prevent tumor invasion and metastasis.

As mass communication is a major topic of interest in American colleges, there is also a growing interest in comparative mass media in other countries. This book is designed to put current practices in the United States in comparative perspective and thus shed new light on American media practices. It is designed as a resource for the growing number of courses dealing with international media, and a recommended supplement for basic mass communications courses that provide a global perspective.
