Differential Multigenomic Effect of Soluble Epoxide Hydrolase Inhibition on the Hippocampal Brain Microvasculature of FeFemale Mice on Low and High Glycemic Diets.


ABSTRACT: Microvascular dysfunction is central to the development of dementia. The effect of high glycemic diet (HGD), independent from dietary fat, on brain microvasculature is crucial, yet an understudied research topic, especially in feFemales. Our study aimed to determine the transcriptomic changes in feFemale brain hippocampal microvasculature induced by a HGD and characterize the response to soluble epoxide hydrolase inhibitor (sEHI). We demonstrated for the first time in feFemales that the HGD had an opposite gene expression profile compared to the LGD and differentially expressed 506 genes, primarily downregulated, with functions related to cell signaling, cell adhesion, cellular metabolism, and neurodegenerative diseases. Surprisingly, the sEHI modified the transcriptome of feFemale mice consuming the LGD more than the HGD, by modulating genes involved in metabolic pathways that synthesize neuroprotective epoxyeicosatrienoic acids (EETs) and associated with a higher EETs/ dihydroxyeicosatrienoic acids (DHETs) ratio.
