Brain tumors, such as those that affect glial cells, are amongst the most lethal of all cancers. Oftentimes, before a cure or treatment for a disease can be developed, it is vital to understand the pathology underlying the disease. Now, scientists at New York Medical College have identified a mechanism by which gliomas spread rapidly through brain tissue and perhaps more importantly, drugs already exist that may be able to curb this spread (Nature Medicine, Vol. 7, No. 9, Sep 01).
Maiken Nedergaard and colleagues have discovered that glioma tumor cells release the neurotransmitter glutamate, which carves a path of destruction through brain tissue allowing the tumor cells to advance. Compounds that block the release of glutamate, such as MK801, were able to slow the growth of tumors implanted in the brains of adult rats.
Jeffrey Rothstein and Henry Brem of Johns Hopkins University discuss how the findings in rats could be extrapolated to humans with brain cancer in an accompanying News & Views article.
