Description

Intracellular checkpoint controls constitute a network of signal transd- tion pathways that protect cells from external stresses and internal errors. Ext- nal stresses can be generated by the continuous assault of DNA-damaging agents, such as environmental mutagens, ultraviolet (UV) light, ionizing radiation, or the reactive oxygen species that can arise during normal cellular metabolism. In response to any of these assaults on the integrity of the genome, the activation of the network of checkpoint control pathways can lead to diverse cellular responses, such as cell cycle arrest, DNA repair, or elimination of the cell by cell death (apoptosis) if the damage cannot be repaired. Moreover, internal errors can occur during the highly orchestrated replication of the cellular genome and its distribution into daughter cells. Here, the temporal order of these cell cycle events must be strictly enforced-for example, to ensure that DNA replication is c- plete and occurs only once before cell division, or to monitor mitotic spindle assembly, and to prevent exit from mitosis until chromosome segregation has been completed. Thus, well functioning checkpoint mechanisms are central to the maintenance of genomic integrity and the basic viability of cells and, the- fore, are essential for proper development and survival. The importance of proper functioning of checkpoints becomes plainly obvious under conditions in which this control network malfunctions and fails. Depending on the severity and timing, failure of this machinery can lead to embryonic lethality, genetic diseases, and cancer.show more

Intracellular checkpoint controls constitute a network of signal transduction pathways that protect cells from external stresses and internal errors by means of cell cycle arrest, DNA repair, or apoptosis. Failure of this machinery can lead to embryonic death, genetic diseases, and cancer. In Checkpoint Controls and Cancer, Volume 1: Reviews and Model Systems, Axel H. Schonthal, PhD, marshals a prestigious panel of researchers working at the cutting edges of their fields to comprehensively review the complexities of checkpoint controls and the model systems available to study them. The authors introduce all of the important components of checkpoint controls, describe their intricate interactions, and highlight the relevance of these processes to the cancer problem. Additional chapters illustrate the advantages of using such diverse model systems as intact human skin, knockout mice, Xenopus, and yeast, and show how they can cross-fertilize and accelerate research both across disciplines and beyond the boundaries of a particular species. A second volume, Activation and Regulation Protocols, provides readily reproducible experimental protocols for studying the molecular components of checkpoint controls and their regulation. Comprehensive and up-to-date, the two volumes of Checkpoint Controls and Cancer offer novice and experienced researchers alike not only entre into the complexities of this vast field, but also to the full panoply of productive tools needed to deepen understanding of the systems, as well as to develop new and more effective cancer therapies."show more
