Protein in the brain could be a key target in controlling Alzheimer's
Date:1/25/2012

that the 12/15-Lipoxygenase protein is a controller of BACE functions," he said. "You don't need to target the Beta secretase directly because the 12/15-Lipoxygenase is really the system in the brain that tells BACE to work more or work less."

Pratico said that they have validated 12/15-Lipoxygenase as a target for a potential Alzheimer drug or therapy.

"By modulating BACE levels and activity through controlling the 12/15-Lipoxygenase, we can potentially improve the cognitive part of the phenotype of the disease, and prevent the accumulation of amyloid beta inside the neurons, which will eventually translate into less of those plaques," he said. "This is a totally new mechanism for controlling BACE."

Pratico said his group has looked at an experimental compound that blocks 12/15-Lipoxygenase function as a potential therapy to inhibit BACE function in the brain. In their lab, using animal models, they saw the drug's ability to restore some cognitive function, as well as improve learning and memory ability.

"There is an opportunity here to study this molecule and develop an even stronger molecule to target 12/15-Lipoxygenase function in the brain," he said.
