CANCER Another Notch for Targeted Therapy?

T cell acute lymphoblastic leukemia (T-ALL) is an aggressive cancer that typically affects children and adolescents. Although the current cure rate is high, T-ALL patients must endure intensive regimens of highly cytotoxic chemotherapy, so there is great interest in developing targeted therapies with fewer side effects. Weng et al. now report that ~50% of T-ALLs have activating mutations in the gene encoding NOTCH1, a transmembrane receptor that regulates T cell differentiation. Together with previous evidence implicating NOTCH1 in cancer development, these results raise the possibility that inhibitors of NOTCH signaling, including the {gamma}-secretase inhibitors, a group of drugs currently being developed for Alzheimer's disease, may merit investigation as anticancer agents.
