Not all depression patients effectively respond to repeated transcranial magnetic stimulation (rTMS). We tested whether the intrinsic functional connectivity (FC) strength between the stimulated left dorsolateral prefrontal cortex (DLPFC) and left nucleus accumbens (NAcc) might predict effects of rTMS. Twenty-two medication-naïve depression patients received rTMS on left DLPFC for 2 weeks and underwent baseline functional magnetic resonance imaging (fMRI). We compared the amplitude of the low-frequency fluctuation (ALFF) and regional homogeneity (ReHo) in the stimulated target (the cortex region directly stimulated by rTMS) located in the left DLPFC, and the left NAcc, as well as the intrinsic FC of the DLPFC-NAcc between early improvers and non-improvers...

Although genome-wide association studies (GWAS) have identified several variants linked to depression, few GWAS of non-European populations have been performed. We conducted a genome-wide analysis of depression in a large, population-based sample of Hispanics/Latinos. Data came from 12,310 adults in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). Past-week depressive symptoms were assessed using the 10-item Center for Epidemiological Studies of Depression Scale. Three phenotypes were examined: a total depression score, a total score modified to account for psychiatric medication use, and a score excluding anti-depressant medication users...

The antidepressant-like effect of chiisanoside from the leaves of Acanthopanax sessiliflorus was evaluated by using mice models of depression, forced swim test (FST) and tail suspension test (TST). The results showed that treatment with chiisanoside at dose of 5.0 mg/kg significantly decreased immobility time in the FST and TST. Pretreatment with haloperidol (a non-selective D2 receptor antagonist), bicuculline (a competitive GABA antagonist) and N-methyl-D-aspartic acid (NMDA, an agonist at the glutamate site) effectively reversed the antidepressant-like effect of chiisanoside (5...

The detoxification enzyme UDP-glucuronosyltransferase UGT2B10 is specialized in the N-linked glucuronidation of many drugs and xenobiotics. Preferred substrates possess tertiary aliphatic amines and heterocyclic amines such as tobacco carcinogens and several anti-depressants and anti-psychotics. We hypothesized that alternative splicing (AS) constitutes a mean to regulate steady state levels of UGT2B10 and enzyme activity. We established the transcriptome of UGT2B10 in normal and tumoral tissues of multiple individuals...

Previous studies have demonstrated that aripiprazole (APZ), a third-generation atypical antipsychotic drug, exhibits anti-depressant and neuroprotective effects by promoting dopaminergic neuronal cell recovery in stroke. To investigate the neuroprotective effects of APZ, behavioral and histopathological experiments were performed in the current study a mouse model of middle cerebral artery occlusion (MCAO)-induced ischemia following administration of APZ. The subacute phase of ischemic assaults was divided into 3 periods, each with a duration of 5 days, according to the start of APZ (3 mg/kg) administration (1-5, 5-9 or 10-14 days following MCAO)...
