Mood disorders are a severe health burden but molecular mechanisms underlying mood dysfunction remain poorly understood. Here, we show that wild-type p53-induced phosphatase 1 (Wip1) negatively responds to the stress-induced negative mood-related behaviors. Specifically, we show that Wip1 protein

Pyridoxal 5'-phosphate (PLP) is an essential cofactor in the catalysis of ~140 different enzymatic reactions. A pharmacological elevation of cellular PLP concentrations is of interest in neuropsychiatric diseases, but whole-body consequences of higher intracellular PLP levels are unknown. To address

Receptor PTPalpha is a widely expressed transmembrane enzyme enriched in brain. PTPalpha knockout (PTPalpha(-/-)) mice are viable and display no gross abnormalities. Brain and embryo derived fibroblast src and fyn activity is reduced to <50% in PTPalpha(-/-) mice. These protein kinases are

BACKGROUND Organ transplant patients receive chronic administration of the calcineurin inhibitor cyclosporin-A (CsA) and demonstrate increased incidence of mood disorders. Significant calcineurin expression can be observed with immunohistochemistry in the amygdala, a brain area important for

Drug relapse among addicts often occurs due to the learned association between drug-paired cues and the rewarding effects of these drugs, such as morphine. Contextual memory associated with morphine has a central role in maintenance and relapse. We showed that morphine-conditioned place preference

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder characterized by impairments in social interaction and communication, and patients often display co-occurring repetitive behaviors. Although the global prevalence of ASD has increased over time, the etiology and treatments for

Receptor protein tyrosine phosphatase rho (RPTPρ, gene symbol PTPRT) is a transmembrane protein expressed at high levels in the developing hippocampus, olfactory bulb, cortex, and cerebellum. It has an extracellular domain that interacts with other cell adhesion molecules, and it has two

Chronic stress can lead to the development of anxiety and mood disorders. Thus, novel therapies for preventing adverse effects of stress are vitally important. Recently, the protein tyrosine phosphatase PTP1B was identified as a novel regulator of stress-induced anxiety. This opens up exciting

Regulator of calcineurin 1 (RCAN1) controls the activity of calcium/calmodulin-dependent phosphatase calcineurin (CaN), which has been implicated in human anxiety disorders. Previously, we reported that RCAN1 functioned as an inhibitor of CaN activity in the brain. However, we now find enhanced

In our biomarker identification efforts, we have reported earlier on a protein that differs in its electrophoretic mobility between mouse lines bred either for high or low trait anxiety. The altered electrophoretic behavior of enolase phosphatase (EP) is now identified to be caused by two

Protein tyrosine phosphatase 1B (PTP1B) has been extensively implicated in the regulation of body weight, food intake, and energy expenditure. The role of PTP1B appears to be cell and brain region dependent. Herein, we demonstrated that chronic high-fat feeding enhanced PTP1B expression in the

Schizophrenia is a debilitating disorder affecting young adults displaying symptoms of cognitive impairment, anxiety, and early social isolation prior to episodes of auditory hallucinations. Cannabis use has been tied to schizophrenia-like symptoms, indicating that dysregulated endogenous

Cholestasis is a pathophysiological process caused by the damage of hepatocytes or obstruction of bile flow, which often leads to emotional disorder in central nervous system. Alpha-naphthylisothiocyanate (ANIT) is the most widely used chemical to induce cholestatic models; however, the

OBJECTIVE This study investigated peripheral and central metabolites affecting depression, anxiety, suicidal ideation, and anger in complex regional pain syndrome (CRPS) patients. METHODS Metabolite levels were determined in the right and left thalamus and insula, in 12 CRPS patients using magnetic
