(Poly)phenols and diabetes: From effects to mechanisms by systematic multigenomic analysis.

Diabetes is a chronic and multifactorial metabolic disease with increasing numbers of patients worldwide, characterized by loss of pancreatic β-cell mass and function with subsequent insulin deficiency. Thus, restoring functional β-cells could significantly impact disease management. The beneficial effects of natural compounds, namely (poly)phenols, in diabetes have gained increasing interest, due to their pleiotropic actions in several cellular processes, including in glucose homeostasis.

Obesity confers risk for cardiovascular disease and vascular dementia. However, genomic alterations modulated by obesity in endothelial cells in the brain and their relationship to other neurovascular unit (NVU) cells are unknown. We performed single nuclei RNA sequencing (snRNAseq) of the NVU (endothelial cells, astrocytes, microglia, and neurons) from the hippocampus of obese (/) and wild-type (WT) male mice to characterize obesity-induced transcriptomic changes in a key brain memory center and assessed blood-brain barrier permeability (BBB) by gadolinium-enhanced magnetic resonance imaging (MRI).

Global genomic profile of hippocampal endothelial cells by single-nuclei RNA sequencing in female diabetic mice is associated with cognitive dysfunction.

Type II diabetes mellitus (T2D) is a chronic metabolic disease and a risk factor for cardiovascular disease and cerebrovascular dysfunction including vascular dementia.

Integrated Analysis of Genomic and Genome-Wide Association Studies Identified Candidate Genes for Nutrigenetic Studies in Flavonoids and Vascular Health: Path to Precision Nutrition for (Poly)phenols.

Flavonoids exert vasculoprotective effects in humans, but interindividual variability in their action has also been reported. This study aims to identify genes that are associated with vascular health effects of flavonoids and whose polymorphisms could explain interindividual variability in response to their intake. Applying the predetermined literature search criteria, we identified five human intervention studies reporting positive effects of flavonoids on vascular function together with global genomic changes analyzed using microarray methods.

The Brain Metabolome Is Modified by Obesity in a Sex-Dependent Manner.

Obesity is linked to cognitive decline and metabolic dysregulation in the brain, yet the role of sex is relatively unexplored. We sought to explore the effects of obesity and sex on the brain metabolome. In male and female and wild-type mice, we assessed whole brain untargeted metabolomics by liquid chromatography-mass spectrometry, behavior by open field test, and cognitive function by Y-maze and Morris water maze.

How promotes transdisciplinary convergence science: an academic health center for women's cardiovascular and brain health.

Cardiovascular disease (CVD) is largely preventable, and the leading cause of death for men and women. Though women have increased life expectancy compared to men, there are marked sex disparities in prevalence and risk of CVD-associated mortality and dementia. Yet, the basis for these and female-male differences is not completely understood.

Gene expression analysis reveals diabetes-related gene signatures.

Background: Diabetes is a spectrum of metabolic diseases affecting millions of people worldwide. The loss of pancreatic β-cell mass by either autoimmune destruction or apoptosis, in type 1-diabetes (T1D) and type 2-diabetes (T2D), respectively, represents a pathophysiological process leading to insulin deficiency. Therefore, therapeutic strategies focusing on restoring β-cell mass and β-cell insulin secretory capacity may impact disease management.

CLPB disaggregase dysfunction impacts the functional integrity of the proteolytic SPY complex.

CLPB is a mitochondrial intermembrane space AAA+ domain-containing disaggregase. CLPB mutations are associated with 3-methylglutaconic aciduria and neutropenia; however, the molecular mechanism underscoring disease and the contribution of CLPB substrates to disease pathology remains unknown. Interactions between CLPB and mitochondrial quality control (QC) factors, including PARL and OPA1, have been reported, hinting at dysregulation of organelle QC in disease.
