Role of cell cycle controllers in the development of cancer

Abstract

In this chapter we introduce proteins controlling transition through the cell division cycle, with particular focus on the controllers of mitosis, and we describe their role in the development of cancer. The essay begins with a historical perspective on the discoveries that led to the formulation of "The Cell Theory" and the understanding of mechanisms controlling cell cycle transitions. This is followed by an in-depth description of pathways that monitor the appropriate completion of events in each phase of the cell division cycle (the checkpoints) and an analysis of the many dysfunctions that alter these mechanisms and account for the occurrence of cancer. The essay is concluded by some considerations on the opportunity of putting effort, both in basic research and drug discovery programs, on the full clarification of the G2/M checkpoint, which is the only checkpoint that tumors in the body and experimental systems have in common. The rationale to this suggestion is that combinations of low-dose radio- or chemotherapy and selective G2/M checkpoint inhibitors will be more effective in achieving tumor clearance than current conventional protocols.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
