Gene expression related to serotonergic and glutamatergic neurotransmission is altered in the flinders sensitive line rat model of depression: effect of ketamine
(Wiley, 2017)
Major depressive disorder (MDD) is associated with dysfunctional serotonergic and glutamatergic neurotransmission, and the genetic animal model of depression Flinders Sensitive Line (FSL) rats display alterations in these ...
S-ketamine rapidly reverses synaptic and vascular deficits of hippocampus in genetic animal model of depression
(Oxford Univ Press, 2017)
Background:
The neurovascular plasticity of hippocampus is an important theory underlying major depression. Ketamine as a novel glutamatergic antidepressant drug can induce a rapid antidepressant effect within hours. In ...
Chronic restraint stress increases the protein expression of VEGF and its receptor VEGFR-2 in the prefrontal cortex
(Wiley, 2015)
In the present study the central and peripheral regulation of VEGF, its cognate receptors, and regulators were examined after acute and chronic restraint stress in rats. After chronic restraint stress (6 h per day for 21 ...
Decreased in vivo α2 adrenoceptor binding in the Flinders Sensitive Line rat model of depression
(Elsevier, 2015)
Depression is a debilitating heterogenous disorder and the underlying mechanisms remain elusive. Alterations in monoaminergic neurotransmission, including noradrenergic, have been implicated in the etiology of depression. ...
Nitric oxide involvement in the antidepressant-like effect of ketamine in the Flinders sensitive line rat model of depression
(Cambridge Univ Press, 2015)
Objective: We investigated whether the nitric oxide (NO) precursor,
L-arginine, can prevent the antidepressant-like action of the fast-acting
antidepressant, ketamine, in a genetic rat model of depression, and/or
induce ...
Selective breeding for high anxiety introduces a synonymous SNP that increases neuropeptide S receptor activity
(Society for Neuroscience, 2015)
Neuropeptide S (NPS) has generated substantial interest due to its anxiolytic and fear-attenuating effects in rodents, while a corresponding
receptor polymorphism associated with increased NPS receptor (NPSR1) surface ...
Antidepressant-like effect of sodium butyrate is associated with an increase in TET1 and in 5-hydroxymethylation levels in the Bdnf gene
(Oxford Univ Press, 2015)
Background: Epigenetic drugs like sodium butyrate (NaB) show antidepressant-like effects in preclinical studies, but the exact molecular mechanisms of the antidepressant effects remain unknown. While research using NaB has ...
Telomerase dysregulation in the hippocampus of a rat model of depression: normalization by lithium
(Oxford Univ Press, 2015)
Background: Telomeres are protective DNA-protein complexes at the ends of each chromosome, maintained primarily by the enzyme telomerase. Shortening of the blood leukocyte telomeres is associated with aging, several chronic ...
Electroconvulsive shocks decrease α2-adrenoceptor binding in the Flinders rat model of depression
(Elsevier, 2015)
Despite years of drug development, electroconvulsive therapy (ECT) remains the most effective treatment for severe depression. The exact therapeutic mechanism of action of ECT is still unresolved and therefore we tested ...
Dietary magnesium deficiency alters gut microbiota and leads to depressive-like behaviour
(Cambridge Univ Press, 2015)
Objective: Gut microbiota (GM) has previously been associated with alterations in rodent behaviour, and since the GM is affected by the diet, the composition of the diet may be an important factor contributing to behavioural ...
