METTL3-dependent m⁶A maturation of miR-140-3p contributes to hippocampal neuronal apoptosis through the OTX2/Wnt/β-catenin axis under chronic stress
Chronic stress contributes to hippocampal neuronal apoptosis and neural circuit dysfunction in major depressive disorder (MDD), but the epitranscriptomic mechanisms regulating stress-responsive microRNAs remain unclear. This study investigated whether methyltransferase-like 3 (METTL3)-mediated N6-methyladenosine (m6A)...
