Surprise: HDAC Goes Down, Not Up, in Alzheimer’s Disease
As gene regulation changes in Alzheimer’s disease,
scientists believe that histone deacetylases (HDACs) go into overdrive,
shutting down transcription of certain genes. Consequently, several research
groups are exploring the potential of HDAC inhibitors as AD therapeutics, with
at least two trials currently enrolling. The recent development of a PET tracer
that recognizes class I HDACs in the brains of living people provides a
valuable tool for such trials. Now, however, the first HDAC PET data from
people with AD upends previous findings. Tharick Pascoal of McGill University,
Montreal, reported that HDAC levels drop as disease advances.
“That was a surprise to us. We expected the opposite
result,” Pascoal told Alzforum. At first, the researchers worried that there
might be errors in their methodology; however, validation by a second group
studying an independent cohort convinced them the finding was real, and robust.
“I’ve never seen two independent PET studies where the images were so similar,”
Pascoal said.
Meanwhile, researchers at the University of California,
Irvine, are investigating the class III HDAC inhibitor nicotinamide for AD.
They wrapped up a Phase 1 safety study of 50 AD patients in 2014 and are
currently enrolling for Phase 2.
