NIH research highlights importance of data-driven approach to identify novel drug targets

Existing and emerging cancer drugs could be repurposed as therapies to be tested in clinical trials for people at genetic risk of Alzheimer’s disease, according to a new study published in Science Advances. Research combining analysis of brain protein alterations in these individuals as well as laboratory experiments in animal models and cell cultures could help scientists identify existing drugs to test for their potential as Alzheimer’s interventions more quickly.

The findings represent efforts from researchers at the National Institute on Aging (NIA), part of the National Institutes of Health; and NIA-supported teams at the University of California, San Francisco; Rush University, Chicago; and the Icahn School of Medicine at Mount Sinai, New York City.

The scientists identified brain protein changes related to the APOE4 genetic risk variant in young postmortem study participants (average age at death was 39 years) and compared these changes with those in the autopsied brains of people with Alzheimer’s and those without (average age at death was 89 years).
