UCLA researchers develop new way to screen for brain cancer stem cell killers
Date:10/11/2011

a large number of brain cancer stem cells in the population. These cells were then screened with a molecular library of 31,624 compounds available through the cancer center's Molecular Screening Shared Resource. These compounds encompass a wide range of structures and therefore have the possibility of influencing virtually all cellular functions.

"We decided on this type of approach because, although we have learned a great deal about brain cancer stem cells in the past several years, we still have not discovered enough of their biology to be sure that any single target will be the right one to hit," Kornblum said.

Going forward, Kornblum and his team will further study the four identified "lead" compounds to see if they help reveal the biology of the brain cancer stem cells and potentially result in a new and more effective therapy for these deadly brain cancers.

"One of our goals was to determine whether some compounds selectively act on glioblastoma stem cells compared to the less tumorigenic cells from the same tumor," the study states. "This selectivity may allow for the delineation of pathways and processes that are highly important to these cells. By making sure that a drug candidate has the potential to attack these stem cells, one might ensure the highest chance of therapeutic success."
