Chemical genetics reveals a complex functional ground state of neural stem cells.
    Nature chemical biology, 2007, Volume: 3, Issue:5

    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.

[Anticancer agents targeting oncogene products].
    Gan to kagaku ryoho. Cancer & chemotherapy, 1993, Volume: 20, Issue:12

    Accumulating evidence indicates that the activation of cellular oncogenes is a cause of some human cancers. ErbB-1, erbB-2 and abl oncogenes encoding tyrosine kinases, ras oncogenes encoding GTP binding proteins and myc oncogenes whose functions are not well understood are some examples. Therefore, agents which inhibit the activity of these oncogene products may provide new means to overcome certain human tumors. Herbimycin A and tyrphostins have been found and developed as inhibitors of tyrosine kinases and the effectiveness of these agents against tumors of Ph1-positive leukemia (CML, ALL) or squamous cell carcinomas has been reported. Although specific inhibitors of ras or myc oncogene products have not yet been described, recent studies on the processing of Ras proteins toward the cell membrane provide a strategy to search for inhibitors of ras functions.
