The study of molecular events leading to cellular transformation and cancer has progressed considerably during the 1990s. It has become apparent that many genes subject to modification in cancer are, in fact, transcription factors that govern the execution of the genetic programme of the cell. Transcription factors can behave either as oncogenes or as tumor supressor genes. To date only a very limited number of transcription factors have been associated with cancer. This volume gives molecular information on several oncogenes, tumor suppressor genes or chromosomal translocations. Each chapter contains a description of the structure of such transcription factors, the nature of target genes, the regulation of their activities and an explaination of how they can deregulate cell growth and differentiation. This book should be suitable for the specialist scientist and the advanced student
