Does EVOO Induce Gene and Metabolic Changes in Healthy Subjects

Sponsor: Augusta University

Summary

Investigators' recent findings from the pilot clinical trial in MCI individuals demonstrated EVOO improved vascular function and memory. Yet, up to date, whether EVOO protects against AD in individuals with a family history of AD is unknown. Thus, in this study, the investigators will recruit healthy individuals with a family history of AD for participation. From eligible participants, blood samples for ApoE genotyping will be collected, followed by metabolomics, lipidomics, and transcriptomics analyses at baseline. Participants will be randomized into 2 groups (n=20 each); one group will receive EVOO daily (\~2 tablespoons, 30 ml) for 6 months, and the second group will not receive olive oil. Both group participants will receive educational information on brain health and how environmental factors such as lifestyle, diet, and exercise could impact brain health. After 6 months, another blood sample will be collected from the participants to evaluate the effect of EVOO on metabolites, lipids, and genes, and thus physiological pathways. The investigators will perform non-targeted and comprehensive metabolomics, lipidomics, and transcriptomics analyses. Examples of metabolites to be analyzed are antioxidative and anti-inflammatory metabolites, neurotransmission, mitochondrial, tryptophan, and purine metabolisms. Examples of lipidomics include sphingomyelins (SMs), cholesterol esters (ChEs), phosphatidylcholines (PCs), phosphatidylethanolamines (PIs), phosphatidylinositols (PIs), and triglycerides (TGs). Transcriptomics will be used to identify changes in mRNAs involved in different pathways contributing to AD, such as genes involved in inflammation and oxidative stress, in both ApoE-dependent and independent fashion.
