The molecular mechanism underlying GABAergic dysfunction in nucleus accumbens of depression-like behaviours in mice.

ABSTRACT: Depression is the most frequent psychiatric disorder in the world. Recent evidence has shown that stress-induced GABAergic dysfunction in the nucleus accumbens (NAc) contributed to the pathophysiology of depression. However, the molecular mechanisms underlying these pathological changes remain unclear. In this study, mice were constantly treated with the chronic unpredictable mild stress (CUMS) till showing depression-like behaviours expression. GABA synthesis, release and uptake in the NAc tissue were assessed by analysing the expression level of genes and proteins of Gad-1, VGAT and GAT-3 by qRT-PCR and Western blotting. The miRNA/mRNA network regulating GABA was constructed based on the bioinformatics prediction software and further validated by dual-luciferase reporter assay in vitro a
