Ethanol Alters DNMT1/3a/3b Expression Profile, Promotes Persistent DNA Hypomethylation in Human Brain Endothelial Cells and Impairs Late Cortical Angiogenesis

Journal of Neurochemistry, Volume 170, Issue 2, February 2026.
Ethanol exposure alters brain endothelial cell function and blood–brain barrier integrity. In human brain microcapillary endothelial cells (HBMEC) and mouse brain endothelial cells (MBEC) from a prenatal alcohol exposure (PAE) model, ethanol increased DNA methyltransferas‐1 (DNMT1) activity and reduced DNA methylation, affecting DNMT3a/3b, methyl‐CpG ...

Defining the Intestinal eCBome and Oxylipin Signaling Systems in a TDP‐43 Mouse Model of Frontotemporal Dementia

The FASEB Journal, Volume 40, Issue 2, 31 January 2026.
TDP‐43 overexpressing mice, a genetic model of frontotemporal dementia, exhibit dramatic changes in their small intestinal endocannabinoidome members, in terms of both altered concentrations of lipid mediators and expression of some of their receptors (Cnr1, Gpr119, Gpr55, Pparg) and metabolic enzymes (Napepld, Faah). Also, the levels of some oxylipins
