The concept of programmed cell death, or apoptosis, hasexploded into a major scientific field of interest for cellbiologists, oncologists, and many other biomedical researchers.Apoptosis occurs throughout the lifetime of most multicellularorganisms. During development, for example, the selective death ofcells is vital to remove tissue between the digits to producefingers and toes. Apoptosis is also necessary to destroy cells thatrepresent a threat to the integrity of the organism, for examplecells infected by a virus. In many cancers the genes regulatingapoptosis are defective, producing immortal, continuouslyproliferating cells. This book discusses the philosophical andtechnical difficulties in defining the moment of death for a cell,as well as the biological implications and significance ofprogrammed cell death. Recent developments in the genetic controland interacting gene networks associated with apoptosis arepresented. The book is written for advanced undergraduate andpostgraduate students, and is
