Official Title
Identification of Epigenetic Markers Common to Obesity and Alzheimer's Disease in Women - Pilot Study
Brief Title
Identification of Epigenetic Markers Common to Obesity and Alzheimer's Disease in Women
Protocol ID
NCT02868905
Lead Sponsor
Central Hospital, Nancy, France
Brief Summary
The purpose of this study is to compare average methylation of epigenetic markers on
genomic DNA and some genes (APP, BACE, LRP, SorL1) involved in cerebral amyloid
homeostasis:
- Of obese young adults and healthy young adults
- Of obese young adults and individuals affected by Alzheimer's disease (AD) having
been obese at young adult age (<50 years old) or individuals affected by Alzheimer's
disease (AD) having never been obese.
The secondary purpose is to determine if there is an association between the frequency of
these epigenetic markers and elements associated to the metabolic syndrome (lipidic and
glycemic analysis, leptinemia, inflammation markers) and clinical ones (visceral fat
mass, body mass index) in young adults.
