Modulation of DNA repair by pharmacological inhibitors of the PIKK protein kinase family.
Modulation of DNA repair pathways in oncology has been an area of intense interest in the last decade, not least as a consequence of the promising clinical activity of poly(ADP-ribose) polymerase (PARP) inhibitors. In this review article, we highlight inhibitors of the phosphatidylinositol 3-kinase related kinase (PIKK) family as of potential interest in the treatment of cancer, both in combination with DNA-damaging therapies and as stand-alone agents. Topics: Animals; Ataxia Telangiectasia Mutated Proteins; Cell Cycle Proteins; DNA; DNA Repair; DNA-Activated Protein Kinase; DNA-Binding Proteins; Humans; Models, Molecular; Neoplasms; Protein Kinase Inhibitors; Protein Serine-Threonine Kinases; Tumor Suppressor Proteins | 2012 |

Chemical genetics reveals a complex functional ground state of neural stem cells.
The identification of self-renewing and multipotent neural stem cells (NSCs) in the mammalian brain holds promise for the treatment of neurological diseases and has yielded new insight into brain cancer. However, the complete repertoire of signaling pathways that governs the proliferation and self-renewal of NSCs, which we refer to as the 'ground state', remains largely uncharacterized. Although the candidate gene approach has uncovered vital pathways in NSC biology, so far only a few highly studied pathways have been investigated. Based on the intimate relationship between NSC self-renewal and neurosphere proliferation, we undertook a chemical genetic screen for inhibitors of neurosphere proliferation in order to probe the operational circuitry of the NSC. The screen recovered small molecules known to affect neurotransmission pathways previously thought to operate primarily in the mature central nervous system; these compounds also had potent inhibitory effects on cultures enriched for brain cancer stem cells. These results suggest that clinically approved neuromodulators may remodel the mature central nervous system and find application in the treatment of brain cancer.
