Researchers studying a mouse model of neurofibromatosis 1 (NF1), a genetic condition that causes childhood brain tumors, have found their second new drug target in a year, a protein called methionine aminopeptidase-2 (MetAP2).
An established drug, fumagillin, is already known to suppress the activity of MetAP2. Researchers at Washington University School of Medicine in St. Louis showed that fumagillin significantly slowed the rapid proliferation of cultured mouse brain cells that resulted from the loss of Nf1, the gene that causes neurofibromatosis 1. Evaluation of the ability of this class of drugs to control brain tumor growth in small animal models is planned.
"This agent and others like it have already been in clinical trials as treatments for other tumors, so if we find that fumagillin inhibits brain tumor growth in preclinical studies, it will be a much smaller leap to using these compounds in patients with NF1," says senior investigator David H. Gutmann, M.D., Ph.D., the Donald O. Schnuck Family Professor of Neurology at Washington University School of Medicine in St. Louis and co-director of the neuro-oncology program at the Siteman Cancer Center.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
