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...

Atractylenolide I (AT-I), a major component of the rhizoma of Atractylodes macrocephala Koidz., exerts a wide range of activities. The purpose of the present study was to investigate the anti-depressant-like effect of AT-I in a mouse model of chronic unpredictable mild stress (CUMS), and to explore the possible molecular mechanism involved. It was revealed that AT-I significantly ameliorated CUMS-induced depressive-like behaviors, as evidenced by increased sucrose preference as well as shortened immobility time in the forced swimming and the tail suspension test...

Recent findings of potential implications of glycogen synthase kinase-3β (GSK-3β) dysfunction in psychiatric disorders like depression, have increased focus for development of GSK-3β inhibitors with possible anti-depressant activity. Keeping this in view, we synthesized a series of benzimidazole-linked-1,3,4-oxadiazole carboxamides and evaluated them for in vitro GSK-3β inhibition. Active compounds were investigated for in vivo antidepressant activity in Wistar rats. Docking studies of active compounds have also been performed...

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)...

Omega-3 polyunsaturated fatty acids (n-3 or omega-3 PUFAs) and melatonin receptor agonist ramelteon (RMT) both display antidepressant effects, while their cellular effects on anti-oxidative and neuroprotective mechanisms might be different. In this study, we aimed to decipher the individual and synergistic actions of n-3 PUFAs and RMT, as compared with the conventional antidepressant fluoxetine (FLX), in a cellular model of oxidative stress, which might play an important role in the pathophysiology of depression and associated disorders...

Early brain injury (EBI) is the primary cause of poor outcome in subarachnoid hemorrhage (SAH) patients. Rolipram, a specific phosphodiesterase-4 inhibitor which is traditionally used as an anti-depressant drug, has been recently proven to exert neuroprotective effects in several central nervous system insults. However, the role of rolipram in SAH remains uncertain. The current study was aimed to investigate the role of rolipram in EBI after SAH and explore the potential mechanism. Adult male Sprague-Dawley rats were subjected to an endovascular perforation process to produce an SAH model...

OBJECTIVES: Ghrelin is an orexigenic digestive hormone that plays a role in sleep and memory. Our work aims is to synthesize the effects of ghrelin on appetite, sleep and memory, and also to evidence its role in depressive disorders.

BACKGROUND: Forty million adults in the US suffer from anxiety disorders, making these the most common forms of mental illness. Transient receptor potential channel canonical subfamily (TRPC) members 4 and 5 are non-selective cation channels highly expressed in regions of the cortex and amygdala, areas thought to be important in regulating anxiety. Previous work with null mice suggests that inhibition of TRPC4 and TRPC5 may have anxiolytic effects. HC-070 IN VITRO: To assess the potential of TRPC4/5 inhibitors as an avenue for treatment, we invented a highly potent, small molecule antagonist of TRPC4 and TRPC5 which we call HC-070...

The functionally selective 5HT-2C receptor ligand SB242084 can increase motivation and have rapid onset anti-depressant like effects. We sought to identify the specific behavioural effects of SB242084 treatment and elucidate the mechanism in female and male mice. Using a quantitative behavioural approach we determined that SB242084 increases the vigor and persistence of goal-directed activity across different types of physical work, particularly when work requirements are demanding. We found this influence of SB242084 on effort, rather than reward to be reflected in striatal dopamine measured during behavior...

Perturbations in stress granule (SG) dynamics may be at the core of amyotrophic lateral sclerosis (ALS). Since SGs are membraneless compartments, modeling their dynamics in human motor neurons has been challenging, thus hindering the identification of effective therapeutics. Here, we report the generation of isogenic induced pluripotent stem cells carrying wild-type and P525L FUS-eGFP. We demonstrate that FUS-eGFP is recruited into SGs and that P525L profoundly alters their dynamics. With a screening campaign, we demonstrate that PI3K/AKT/mTOR pathway inhibition increases autophagy and ameliorates SG phenotypes linked to P525L FUS by reducing FUS-eGFP recruitment into SGs...

BACKGROUND: The long-term course of symptoms in patients with mild-to-moderate depression is not well understood. A 12-month-follow-up analysis was performed on those participants from a randomized controlled 10-week trial (RCT, MIND-study), who had received either treatment with an antidepressant (sertraline) or a psychotherapeutic intervention (group cognitive-behavioral therapy (CBT)). METHODS: The longitudinal interval follow-up evaluation (LIFE) was applied to 77 patients with mild-to moderate depression...

Ketamine is a dissociative anaesthetic drug which acts on the central nervous system chiefly through antagonism of the n-methyl-d-aspartate (NMDA) receptor. Recently, ketamine has attracted attention as a rapid-acting anti-depressant but other studies have also reported its efficacy in reducing problematic alcohol and drug use. This review explores the preclinical and clinical research into ketamine's ability to treat addiction. Despite methodological limitations and the relative infancy of the field, results thus far are promising...

Acute or chronic exposure to stress can increase the risk to develop major depressive disorder, a severe, recurrent and common psychiatric condition. Depression places an enormous social and financial burden on modern society. Although many depressed patients are treated with antidepressants, their efficacy is only modest, underscoring the necessity to develop clinically-effective pharmaceutical or behavioral treatments. Exercise training produces beneficial effects on stress-related mental disorders, indicative of clinical potential...

INTRODUCTION: Incensole can be considered as a biomarker for Boswellia species which is a diterpene that has received remarkable pharmacological interest recently due to its potent anti-inflammatory and anti-depressant activity. OBJECTIVE: Near-infrared (NIR) spectroscopy coupled with PLSR (partial least squares regression) as a robust, rapid and alternative method was used to quantify the content of incensole in three species namely B. papyrifera, B. sacra and B...

ETHNOPHARMACOLOGY RELEVANCE: Gastrodia elata Blume (GE) is a traditional Chinese medicine commonly used to treat dizziness, epilepsy, paralysis and some emotional symptoms in east Asia. We previously showed that the water extract of Gastrodia elata Blume (WGE) possesses anti-depression like effects in a forced swimming test and chronic mild stress model. AIM OF THE STUDY: The aim of this study was to investigate the antidepressant-like effects of WGE and potential mechanisms related to brain-derived neurotrophic factor (BDNF) regulation in mice exposed to chronic social defeat stress (CSDS) model...

BACKGROUND: The incidence of thyroid cancer has increased significantly over the last ten years and conversely the mortality has decreased. With 85% of patients with thyroid cancer surviving for ten years or longer it is increasingly important to study the quality of life in these patients and identify which aspects of the patients' health and wellbeing could be improved. METHODS: During the first UK patient-doctor thyroid cancer forum, patient attendees filled in an anonymized questionnaire...
