At the moment, there is no dedicated book to summarize the roles, the significance, and potential therapeutic targeting of transcriptional factors from the perspective of signaling cascade, and thus, directly impacting the functionality of transcriptional factors in cancer. In addition, this book will offer a comprehensive basic and clinical science behind the functions of representative core transcriptional factors. These chapters will serve as a treasure for all those who have an interest in the basis, progression, and targeting of human cancer. Each chapter will be intended to provide comprehensive, up-to-date information by the leaders about the physiologic and pathologic roles of TFs in specific representative organ systems of prime importance. The book will consist of chapters that will give biomedical students, under and graduate students, basic sciences and clinical cancer fellows, residents and researchers, and oncology educators will get a thorough summary of the overall subject. The readers will be able to understand the important current information and views on specific TFs and its role in cancer in areas outside their own expertise or experience. A special emphasis will be also placed on the classic papers as well as perspectives on future directions for the field.
