Cell Cycle Inhibition in Malignant Lymphoma: Disease Control by Attacking the Cellular Proliferation Machinery
Abstract:Disruption of a proper regulation of cell proliferation can ultimately cause cancer. Most human B cell malignancies are driven by chromosomal translocations or other genetic alterations which directly affect the function of critical cell cycle proteins, such as cyclins and cyclin-dependent kinases. In addition, the transformation of indolent lymphomas into aggressive malignancies is often accompanied by a loss of tumor suppressors controlling important cell cycle checkpoints. A better understanding of cell cycle deregulations in human tumors has promoted the introduction of a new class of antiproliferative drugs into cancer therapies. These drugs exert their function by specifically blocking important cell cycle proteins. In the present review we discuss how alterations in the cell cycle control contribute to the malignant transformation of B cells. Furthermore, we provide an overview of novel direct and indirect cell cycle inhibitors and their impact on the treatment of patients with B cell lymphomas.

More about this publication?
- Current Drug Targets aims to cover the latest and most outstanding developments on the medicinal chemistry and pharmacology of molecular drug targets e.g. disease specific proteins, receptors, enzymes, genes. Each issue of the journal will be devoted to a single timely topic, with series of in-depth reviews, written by leaders in the field, covering a range of current topics on drug targets. These issues will be organized and led by a guest editor who is a recognized expert in the overall topic. As the discovery, identification, characterisation and validation of novel human drug targets for drug discovery continues to grow; this journal will be essential reading for all pharmaceutical scientists involved in drug discovery and development.
