REVIEW
Florian Bähner, Andreas Meyer-Lindenberg
Finding novel biological targets in psychiatry has been difficult, partly because current diagnostic categories are not defined by pathophysiology and difficult to model in animals. The study of species-conserved systems-level mechanisms implicated in psychiatric disease could be a promising strategy to address some of these difficulties. Altered hippocampal-prefrontal (HC-PFC) connectivity during working memory (WM) processing is a candidate for such a translational phenotype as it has been repeatedly associated with impaired cognition in schizophrenia patients and animal models for psychiatric risk factors...

BACKGROUND: Obesity has a multifaceted etiology that involves genetic, biological and behavioral factors, body growth, eating habits, energy expenditure and the function of adipose tissue. The present study aimed to expand upon knowledge about the relationships among obesity, emotions and eating habits in severely obese individuals using a case-control method. METHODS: The subject group consisted of 112 individuals (81 females and 31 males) receiving a permanent disability pension primarily for obesity...

Neuropeptide Y (NPY) has been found to play a critical role in various mental functions as a neurotransmitter and is involved in the development of schizophrenia, a particularly intractable psychiatric disease whose precise etiology remains unknown. Recent molecular biological investigations have identified several candidate genes which may be associated with this disease, including disrupted-in-schizophrenia 1 (DISC1). The role of DISC1 would involve neurogenesis and neuronal migration. However, the functional consequences of this gene defect have not yet been fully clarified in neuronal systems...

We performed a genome-wide association study of 6447 bipolar disorder (BD) cases and 12 639 controls from the International Cohort Collection for Bipolar Disorder (ICCBD). Meta-analysis was performed with prior results from the Psychiatric Genomics Consortium Bipolar Disorder Working Group for a combined sample of 13 902 cases and 19 279 controls. We identified eight genome-wide significant, associated regions, including a novel associated region on chromosome 10 (rs10884920; P=3.28 × 10(-8)) that includes the brain-enriched cytoskeleton protein adducin 3 (ADD3), a non-coding RNA, and a neuropeptide-specific aminopeptidase P (XPNPEP1)...

Protein kinase CK2 has received a surge of attention in recent years due to the evidence of its overexpression in a variety of solid tumors and multiple myelomas as well as its participation in cell survival pathways. CK2 is also upregulated in the most prevalent and aggressive cancer of brain tissue, glioblastoma multiforme, and in preclinical models, pharmacological inhibition of the kinase has proven successful in reducing tumor size and animal mortality. CK2 is highly expressed in the mammalian brain and has many bona fide substrates that are crucial in neuronal or glial homeostasis and signaling processes across synapses...

Clinical usage of several classes of antibiotics is associated with moderate to severe side effects due to the promotion of mitochondrial dysfunction. We contend that this may be due to perturbation of unique evolutionary relationships that link selective biochemical and molecular aspects of mitochondrial biology to conserved enzymatic processes derived from bacterial progenitors. Operationally, stereo-selective conformational matching between mitochondrial respiratory complexes, cytosolic and nuclear signaling complexes appears to support the conservation of a critically important set of chemical messengers required for existential regulation of homeostatic cellular processes...

More than 800 G protein-coupled receptor (GPCR) genes have been discovered in the human genome. Towards the next step in GPCR research, we performed a knowledge-driven analysis of orphan class-A GPCRs that may serve as novel targets in drug discovery. We examined the relationship between 61 orphan class-A GPCR genes and diseases using the Online Mendelian Inheritance in Man (OMIM) database and the DDSS tool. The OMIM database contains data on disease-related variants of the genes. Particularly, the variants of GPR101, GPR161, and GPR88 are related to the genetic diseases: growth hormone-secreting pituitary adenoma 2, pituitary stalk interruption syndrome (not confirmed), and childhood-onset chorea with psychomotor retardation, respectively...

BACKGROUND: procrastination refers to the delay or postponement of task or decision-making initiation or completion and is often conceptualised as a failure of self-regulation. Recent research has suggested that metacognitions play a role in procrastination and that unintentional procrastination (UP), as opposed to intentional procrastination (IP), may be the most problematic form of this behaviour. We aimed to test a metacognitive model of procrastination that was grounded in the Self-Regulatory Executive Function model...

: Organismal stress initiates a tightly orchestrated set of responses involving complex physiological and neurocognitive systems. Here, we present evidence for glucagon-like peptide 1 (GLP-1)-mediated paraventricular hypothalamic circuit coordinating the global stress response. The GLP-1 receptor (Glp1r) in mice was knocked down in neurons expressing single-minded 1, a transcription factor abundantly expressed in the paraventricular nucleus (PVN) of the hypothalamus. Mice with single-minded 1-mediated Glp1r knockdown had reduced hypothalamic-pituitary-adrenal axis responses to both acute and chronic stress and were protected against weight loss associated with chronic stress...

Deficits in the domains of attention and response inhibition are central to many psychiatric disorders. As such, animal models of disorders purporting to replicate these behavioral deficits first require tests that can accurately assess the behaviors with high fidelity. The gold-standard clinical test of attention and response inhibition is the continuous performance test (CPT). Although there are a number of CPTs, all share the premise of responding to target stimuli and inhibiting from responding to non-target stimuli...

Major depressive disorder (MDD) represents a major social and economic health issue and constitutes a major risk factor for suicide. The molecular pathology of suicidal depression remains poorly understood, although it has been hypothesised that regulatory genomic processes are involved in the pathology of both MDD and suicidality. In this study, genome-wide patterns of DNA methylation were assessed in depressed suicide completers (n=20) and compared with non-psychiatric, sudden-death controls (n=20) using tissue from two cortical brain regions (Brodmann Area 11 (BA11) and Brodmann Area 25 (BA25))...

A powerful new method is described called Knowledge based functional connectivity Enrichment Analysis (KEA) for interpreting resting state functional connectivity, using circuits that are functionally identified using search terms with the Neurosynth database. The method derives its power by focusing on neural circuits, sets of brain regions that share a common biological function, instead of trying to interpret single functional connectivity links. This provides a novel way of investigating how task- or function-related related networks have resting state functional connectivity differences in different psychiatric states, provides a new way to bridge the gap between task and resting-state functional networks, and potentially helps to identify brain networks that might be treated...

Studies using genome-wide association (GWA) single nucleotide polymorphism (SNP) level data have indicated genetic overlap across the five major disorders in the Psychiatric Genomics Consortium (PGC): attention deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD), bipolar disorder (BPD), major depressive disorder (MDD), and schizophrenia (SCZ). However, such SNP-level analyses reveal little about the underlying biology and are reliant on correlated SNP effects across disorders. In contrast to SNPs, genes are more closely related to biology and gene-based tests can incorporate allelic heterogeneity...

Functional neurosurgery has undergone rapid growth over the last few years fueled by advances in imaging technology and novel treatment modalities. These advances have led to new surgical treatments using minimally invasive and precise techniques for conditions such as Parkinson's disease, essential tremor, epilepsy, and psychiatric disorders. Understanding the goals and technological issues of these procedures is imperative for the anesthesiologist to ensure safe management of patients presenting for functional neurosurgical procedures...

Despite evidence for both physical and mental health benefits achieved through regular exercise, most Americans fail to meet minimum recommendations. Altering the behavioral contingency from a focus on long-term health benefits to immediate mood benefits represents a novel method for exercise promotion. The current study examined a single-session exercise-for-mood intervention against two time-matched comparison conditions in 152 patients with serious mental illness attending a partial hospital program, a population marked by significant health disparities...

Cutis Verticis Gyrata-Intellectual Disability (CVG-ID) syndrome is a rare neurocutaneous syndrome characterized by intellectual disability and scalp folds and furrows that are typically absent at birth and are first noticed after puberty. First reported in 1893, the syndrome was mainly identified in subjects living in psychiatric institutions, where it was found to have a prevalence of up to 11.4%. Most patients were reported in the literature during the first half of the 20th century. CVG-ID is now a less reported and possibly under-recognized syndrome...

Scientific interest in serotonergic psychedelics (e.g., psilocybin and LSD; 5-HT2A receptor agonists) has dramatically increased within the last decade. Clinical studies administering psychedelics with psychotherapy have shown preliminary evidence of robust efficacy in treating anxiety and depression, as well as addiction to tobacco and alcohol. Moreover, recent research has suggested that these compounds have potential efficacy against inflammatory diseases through novel mechanisms, with potential advantages over existing antiinflammatory agents...

Alcoholism is a psychiatric condition that develops through neuroadaptations in response to neuronal stresses caused by chronic ethanol intake. Neurons can adapt to ethanol-induced metabolic changes by activating cellular protective mechanisms, including autophagy. Here we show that expression of Ulk1, a gene critical to the regulation of autophagy, was affected in the prefrontal cortex (PFC) of mice following chronic intermittent ethanol (CIE) exposure. Consequently, overall levels of Ulk1 activity in the PFC were downregulated, leading to accumulation of p62, a protein that serves as a target for autophagic degradation...

BACKGROUND: Understanding brain function requires knowledge of how one brain region causally influences another. This information is difficult to obtain directly in the human brain, and is instead typically inferred from resting-state fMRI.

GM2 gangliosidoses are a group of lysosomal storage disorders which include Sandhoff disease and Tay-Sachs disease. Dysregulation of glutamate receptors has been recently postulated in the pathology of Sandhoff disease. Glutamate receptor association with neuronal pentraxins 1 and 2, and the neuronal pentraxin receptor facilitates receptor potentiation and synaptic shaping. In this study, we have observed an upregulation of a novel form of neuronal pentraxin 1 (NP1-38) in the brains of a mouse model of Sandhoff disease and Tay-Sachs disease...
