Dr. Greg M. Cole is currently a Professor of Medicine and Neurology at
UCLA where he is also the Associate Director of the Mary Easton
Alzheimer's Center at UCLA and Associate Director for Preclinical
Research at the Geriatric Research, Education and Clinical Center for
the Greater Los Angeles Veterans Administration System. After receiving
undergraduate degrees in Physics and Biochemistry from University of
California at Berkeley and working in an immunology lab at Harvard
Medical School, he returned to Berkeley for a doctoral program on
Alzheimer's and aging with Dr Paola Timiras and moved to San Diego for
postdoctoral work on Alzheimer's at UCSD with Dr. Tsunao Saitoh. He is
a recipient of the Cherkin Award for Research on Brain Aging.
Dr Cole’s research over the last two decades has been
centered on the production and role of beta amyloid in Alzheimer's
disease. He worked with Dr. K. Hsiao to develop the first successful
academic transgenic mouse model for AD (1). Based in part on a series
of screens in pre-clinical models from his group, four compounds,
ibuprofen (2) R-flurbiprofen (4), curcumin (3,6) and DHA(5, 7) have
advanced to clinical trials for Alzheimer’s. His recent
papers investigate the potential for AD prevention with omega 3 fatty
acid (DHA, docosahexaenoic acid from fish) and its role in preventing
amyloid formation and abeta toxicity, notably through induction of the
Alzheimer protective gene, SorLA (9) and prevention of
insulin/neurotrophic factor resistance. His lab is also exploring the
efficacy of the curry spice extract, curcumin, to control inflammation
and oxidative damage and to act directly on insoluble amyloid fibrils
in plaques and more soluble toxic species in vitro and in vivo. Dr.
Cole and his colleague Dr. Sally Frautschy, have developed a much more
bioavailable formulation of curcumin that is in current and planned
clinical trials for both Alzheimer’s and cancer (10). The lab
is also examining the role of omega 3 and other dietary fatty acids to
control of a neuroprotective “insulin” or trophic
factor signaling pathway (IR>IRS-1>PI3-kinase>Akt
> GSK3 that is deranged in AD- as well as synaptic protein loss
and abeta oligomer induced cognitive deficits. His group has presented
evidence implicating aberrant activation of a “mental
retardation” pathway as the mechanism underlying synaptic
deficits in AD (8,11). Dr. Cole also works with Dr. Bruce Teter in the
lab on role of Apolipoprotein E as a risk factor for
Alzheimer’s disease and defective recovery after injury using
transgenic mouse models and with Dr. Karen Gylys on synaptic defects
analyzed by flow cytometry. Other recent contributions include a role
in the development of an amyloid and tangle PET imaging probe with UCLA
colleagues Drs G. Small and J. Barrio. Much of the work of the Cole and
Frautschy labs is based on an analysis of environmental risk factors,
notably NSAIDs, fats and antioxidants as well as development of other
anti-amyloid agents in animal models for the disease. They are
currently evaluating agents from a variety of sources including the
Easton Drug Discovery Program using multiple animal models for
Alzheimer’s disease. The primary goal of his lab is to
develop safe and widely available methods for the prevention of
Alzheimer's and possibly other degenerative diseases of aging.
