The book on ‘Cell Cycle Checkpoints and Cancer’, edited by Mikhail Blagosklonny, is such a brave attempt, and a very successful one indeed. The editor himself is one of the recognized leading ...

The cell must also pass through a series of checkpoints that ensure conditions are favorable for division. In order to move from one phase of its life cycle to the next, a cell must pass through ...

Ph.D., and Robert Whitaker have found a direct link between the protein MCL1 -- a member of the large BCL2 protein family known as the gatekeepers of apoptosis -- and a cell-cycle checkpoint ...

Thus, abrogation of cell cycle checkpoints, before DNA repair is complete, can activate the apoptotic cascade, leading to cell death. Now in clinical trials are a series of targeted agents that ...

From this and other discoveries, including the discovery of the RAD9 gene with former postdoc Ted Weinert, Hartwell hypothesized that checkpoints regulate the sequence of events in mitosis.1 His ...

Through these events, normal cells can become malignant. PT162 was designed to act as a p53-reactivating cell cycle checkpoint inhibitor, inducing cancer cell cycle arrest and/or apoptosis by ...

In essence, cell cycle arrest at these critical checkpoints represents a survival mechanism, which provides the tumor cell the opportunity to escape the effects of lethal DNA damage induced by ...

CDKs function to phosphorylate many different proteins which are required for passing important points in the cell cycle, called checkpoints. These checkpoints are present at the end of G1 and the ...
