The process of metastasis formation is hugely complex, as described in the introductory chapter of this book, and this complexity has led us to compile two volumes of methods, from a vastly divergent background that attempts to encompass the whole spectrum of cancer biology. This first volume, Metastasis Research Protocols: Analysis of Cells and Tissues, concentrates on analysis and mapping of molecules produced by cells and tissues and analysis of the molecular biology underlying their expression, whereas the second volume, Metastasis Research Protocols: Cell Behavior In Vitro and In Vivo,focuses sharply on the determination of cell behavior in vitro and in vivo. We have deliberately included chapters describing well-established and familiar te- niques (for example, SDS-PAGE and Western blotting [Chapter 11], and immunocytochemistry [Chapter 2]) in addition to the newer and more speci- ized approaches and specific examples of their application, because-although the methodology is readily available in the published literature and established in many laboratories-we wished these volumes to "stand alone" and to make accessible here the standard techniques that underpin much metastasis research for both the newcomer to the field and the seasoned researcher. Undoubtedly, owing to the complexity of the metastatic cascade and the wealth of research techniques involved in scientific approaches to its unraveling, and despite our best efforts to make these volumes as comprehensive as seems feasible, this is a tall order, and there will inevitably be omissions. For these we apologize. Although ninety percent of fatal cancer cases involve the spread of a primary tumor, the formation of metastases is still a poorly understood, complex process and a significant problem in the treatment of cancer patients. In Metastasis Research Protocols, leading international investigators describe the key methods needed to investigate why and how metastasis occurs. Volume I of this two-volume set, Analysis of Cells and Tissues, presents a comprehensive collection of established and leading-edge techniques for analyzing the expression of key molecules and for examining their production at the genetic level. The work focuses on the analysis and mapping of molecules produced by cells and tissues, and on the molecular biology underlying their expression. The traditional methods range from the histopathological and the immunocytochemical to SDS-PAGE, Western blotting, and enzyme zymography. Newer and more specialized techniques for analyzing the genetic aspects of metastasis include in situ hybridization to localize mRNAs, FISH, CGH, methylation analysis of CpG islands, RT-PCR, and differential display. The second volume of this set, Analysis of Cell Behavior In Vitro and In Vivo, moves to the level of living cells and tissues to present methodologies applicable to examining metastatic behavior in vitro and in the whole animal.
Comprehensive and authoritative, the two volumes of Metastasis Research Protocols constitute a gold-standard collection of readily reproducible methods for understanding the metastatic cascade-first at the cellular and molecular levels, then at the level of the whole organism-responsible for the spread of cancer and for developing novel strategies to combat its spread.
