The Dopamine B-Hydroxylase 19 Bp Insertion/Deletion Polymorphism Was Associated With First-Episode But Not Medicated Chronic Schizophrenia, Li Hui, Xuan Zhang, Xu-Feng Huang, Mei Han, Francesca Fernandez, Yaqin Yu, Shilong Sun, Wenjun Li, Da Chen, Mei Xiu, Thomas Kosten, Xiang Zhang

Xu-Feng Huang

Background: Numerous studies report dysfunctional dopaminergic and noradrenergic neurotransmission in the pathogenesis of schizophrenia. Dopamine beta-hydroxylase (DBH) is an intracellular enzyme catalyzing the conversion of dopamine to noradrenaline. Functional polymorphisms have been reported in the promoter region of DBH gene, including a 19 bp insertion/deletion polymorphism. The purpose of this study was to investigate whether there was an association between the functional polymorphism (DBH50-Ins/Del) and schizophrenia in a Han Chinese population. Methods: This polymorphism was genotyped in 221 first-episode schizophrenics, 360 chronic schizophrenics and 318 healthy controls using a case-control design. We assessed their psychopathology using the Positive and Negative …

Alterations In 5-Ht2a Receptor Binding In Various Brain Regions Among 6-Hydroxydopamine-Induced Parkinsonian Rats, Yun Li, Xu-Feng Huang, Chao Deng, Barbara Meyer, Aimin Wu, Yinghua Yu, Weihai Ying, Guo-Yuan Yang, Midori Yenari, Qing Wang Feb 2013

Alterations In 5-Ht2a Receptor Binding In Various Brain Regions Among 6-Hydroxydopamine-Induced Parkinsonian Rats, Yun Li, Xu-Feng Huang, Chao Deng, Barbara Meyer, Aimin Wu, Yinghua Yu, Weihai Ying, Guo-Yuan Yang, Midori Yenari, Qing Wang

Xu-Feng Huang

The serotonergic system has close interactions with the dopaminergic system and is strongly implicated in the pathophysiological mechanisms and therapeutic paradigms of Parkinson’s disease (PD). This study aims to investigate regional changes in 5-hydroxytryptamine (5-HT) 2A receptors in the rat brain 3 weeks after unilateral medial forebrain bundle lesion by 6-hydroxydopamine (6-OHDA). 5-HT 2A receptor distributions and alterations in the postmortem rat brain were detected by [3H]ketanserin-binding autoradiography. In the 6-OHDA-induced Parkinson’s rat model, nigrostriatal dopaminergic neuron loss significantly mediated the decreased [3H]ketanserin binding, predominantly in the agranular insular cortex (17.3%, P 5 0.03), cingulate cortex (18.2%, P < 0.001), prefrontal …


The Role Of Histaminergic H1 And H3 Receptors In Food Intake: A Mechanism For Atypical Antipsychotic-Induced Weight Gain?, Chao Deng, Katrina Western-Green, Xu-Feng Huang Feb 2013

The Role Of Histaminergic H1 And H3 Receptors In Food Intake: A Mechanism For Atypical Antipsychotic-Induced Weight Gain?, Chao Deng, Katrina Western-Green, Xu-Feng Huang

Xu-Feng Huang

Atypical antipsychotics such as olanzapine and clozapine are effective at treating the multiple domains of schizophrenia, with a lowrisk of extra-pyramidal side-effects. However amajor downfall to their use is metabolicside-effects particularly weight gain/obesity,which occurs by unknownmechanisms. The present paper explores the potential candidature of histaminergic neurotransmission in the mechanisms of atypical antipsychoticinduced weight gain, with a focus on the histaminergic H1 and H3 receptors. Olanzapine and clozapine have a high affinity for the H1 receptor, andmeta-analyses showa strong correlation between risk ofweight gain andH1 receptor affinity. In addition, olanzapine treatment decreases H1 receptor binding and mRNA expression in the rat …


Effects Of Simvastatin And 6-Hydroxydopamine On Histaminergic H1 Receptor Binding Density In Rat Brains, Chang-Hua Hu, Chao Deng, Nikolce Mackovski, Ling Long, Cansheng Zhu, Yu Yang, Yuge Wang, J-Z Chen, Xu-Feng Huang, Qing Wang Feb 2013

Effects Of Simvastatin And 6-Hydroxydopamine On Histaminergic H1 Receptor Binding Density In Rat Brains, Chang-Hua Hu, Chao Deng, Nikolce Mackovski, Ling Long, Cansheng Zhu, Yu Yang, Yuge Wang, J-Z Chen, Xu-Feng Huang, Qing Wang

Xu-Feng Huang

Statins have been widely used for the treatment of a variety of medical conditions including psychoneurological disorders beyond their original use in lowering cholesterol. Histamine receptors play an important role in the regulation of neural activity, however, it is unknown whether statins act on histamine receptors, particularly for their neural regulatory effects. This study examined the effects of simvastatin and 6-hydroxydopamine (6-OHDA) lesions on histamine H1 receptors using [3H] pyrilamine binding autoradiography. Compared to the saline group, simvastatin (1 mg/kg/day) significantly decreased H1 receptor bindings in the primary motor cortex (M1), ventromedial hypothalamic nucleus (VMH), caudate putamen (CPu), accumbens core …


Structural Contributions Of Antipsychotic Drugs To Their Therapeutic Profiles And Metabolic Side Effects, Somayeh Jafari, Francesca Fernandez-Enright, Xu-Feng Huang Feb 2013

Structural Contributions Of Antipsychotic Drugs To Their Therapeutic Profiles And Metabolic Side Effects, Somayeh Jafari, Francesca Fernandez-Enright, Xu-Feng Huang

Xu-Feng Huang

Antipsychotic drugs have various neuropharmacological properties as a result of their structural diversity. Despite their therapeutic benefits, most of the prescribed atypical antipsychotics can induce severe side effects, including weight gain, type II diabetes mellitus, and cardiovascular diseases. Among the developed atypical antipsychotic agents, tetracyclic dibenzodiazepine and thienobenzodiazepine compounds, particularly clozapine and olanzapine, are associated with the greatest weight gain and metabolic disturbances. However, the unique chemical structure of these compounds causes the low risk of side effects reported for typical antipsychotics (e.g. extrapyramidal symptoms and tardive dyskinesia). This report reviews the recent discovery of the potential role of the …

Developmental Vitamin D Deficiency Alters Mk-801-Induced Behaviours In Adult Offspring, James Kesby, Jonathan O'Loan, Suzanne Alexander, Chao Deng, Xu-Feng Huang, John Mcgrath, Darryl Eyles, Thomas Burne Feb 2013

Developmental Vitamin D Deficiency Alters Mk-801-Induced Behaviours In Adult Offspring, James Kesby, Jonathan O'Loan, Suzanne Alexander, Chao Deng, Xu-Feng Huang, John Mcgrath, Darryl Eyles, Thomas Burne

Xu-Feng Huang

Rationale Developmental vitamin D (DVD) deficiency is a candidate risk factor for developing schizophrenia in humans. In rodents DVD deficiency induces subtle changes in the way the brain develops. This early developmental insult leads to select behavioural changes in the adult, such as an enhanced response to amphetamine-induced locomotion in female DVD-deficient rats but not in male DVDdeficient rats and an enhanced locomotor response to the Nmethyl- D-aspartate (NMDA) receptor antagonist, MK-801, in male DVD-deficient rats. However, the response to MK- 801-induced locomotion in female DVD-deficient rats is unknown. Therefore, the aim of the current study was to further examine …


Reciprocal Signalling Between Nr2 Subunits Of The Nmda Receptor And Neuregulin 1 And Their Role In Schizophrenia, Amy Geddes, Xu-Feng Huang, Kelly A. Newell Feb 2013

Reciprocal Signalling Between Nr2 Subunits Of The Nmda Receptor And Neuregulin 1 And Their Role In Schizophrenia, Amy Geddes, Xu-Feng Huang, Kelly A. Newell

Xu-Feng Huang

Schizophrenia is a debilitating neurodevelopmental psychiatric disorder. Both the N-methyl-D-aspartate receptor (NMDAR) and neuregulin1 (NRG1) are key molecules involved in normal brain development that have been linked to schizophrenia pathology and aetiology. The NR2 proteins are critical structural and functional subunits of the NMDAR and are developmentally and spatially regulated. Altered NR2 gene and protein expression has been found in human post-mortem schizophrenia brain tissue together with changes in NRG1 and its receptor ErbB4. The NR2 subunits and ErbB4 share a common anchoring domain on the postsynaptic density and therefore a disruption to either of these molecules may influence the …


The Effects Of Antipsychotic Drugs Administration On 5-Ht1a Receptor Expression In The Limbic System Of The Rat Brain, Mei Han, Xu-Feng Huang, Teresa Du Bois, Chao Deng Feb 2013

The Effects Of Antipsychotic Drugs Administration On 5-Ht1a Receptor Expression In The Limbic System Of The Rat Brain, Mei Han, Xu-Feng Huang, Teresa Du Bois, Chao Deng

Xu-Feng Huang

Increasing evidence suggests that 5-HT1A receptors are involved in the pathophysiology and treatment of schizophrenia. This paper investigated 5-HT1A receptor mRNA expression and binding density in female rats treated with aripiprazole (2.25 mg/kg/day), olanzapine (1.5 mg/kg/day), haloperidol (0.3 mg/kg/day) or vehicle (control) orally three times/day for 1 or 12 weeks. Animals were sacrificed 48 h after the last administration. Aripiprazole significantly increased 5-HT1A receptor binding density by 33% in the CA1 region of the hippocampus and by 21% in the medial posterodorsal nuclei of posterior amygdala (MeP) compared to the control group after 1 week of treatment. Olanzapine significantly decreased …

Density Of Metabotropic Glutamate Receptors 2 And 3 (Mglur2/3) In The Dorsolateral Prefrontal Cortex Does Not Differ With Schizophrenia Diagnosis But Decreases With Age, Elisabeth Frank, Kelly Newell, Xu-Feng Huang Feb 2013

Density Of Metabotropic Glutamate Receptors 2 And 3 (Mglur2/3) In The Dorsolateral Prefrontal Cortex Does Not Differ With Schizophrenia Diagnosis But Decreases With Age, Elisabeth Frank, Kelly Newell, Xu-Feng Huang

Xu-Feng Huang

Metabotropic glutamate receptors 2 and 3 (mGluR2/3) have been shown as efficient targets for antipsychotic intervention. We therefore investigated the receptor density of mGluR2/3 in the dorsolateral prefrontal cortex (dlPFC; Brodman area 46) of schizophrenia/schizoaffective patients (n=37) and matched controls (n=37) using receptor autoradiography. No difference in mGluR2/3 density was identified in relation to schizophrenia diagnosis. Overall and in individual groups, a negative correlation of mGluR2/3 density and age at death has been found. These and previous results suggest that density of mGluR2/3 in the dlPFC is less likely to impact on the efficiency of the mGluR2/3 agonist in treating …


Antipsychotic Treatment And Neuregulin 1 -Erbb4 Signalling In Schizophrenia, Bo Pan, Xu-Feng Huang, Chao Deng Feb 2013

Antipsychotic Treatment And Neuregulin 1 -Erbb4 Signalling In Schizophrenia, Bo Pan, Xu-Feng Huang, Chao Deng

Xu-Feng Huang

Evidence from genetic, transgenic and post-mortem studies has strongly supported the critical role that neuregulin 1 (NRG1) and its ErbB4 receptor plays in the pathophysiology of schizophrenia. This article aims to review current evidence regarding the effects of antipsychotic treatment on NRG1–ErbB4 signalling. NRG1 and ErbB4 knockout mice display abnormal behaviours relevant to certain features of schizophrenia, which could be improved by antipsychotic (clozapine/haloperidol) treatment. In contrast to most NRG1/ErbB4 knockout mice with a decreased NRG1–ErbB4 signalling, the majority post-mortem studies showed an increased NRG1–ErbB4 signalling in schizophrenic patients. These differences could be due to degrees of alteration in risk …

Xu-Feng Huang

Background: G-protein coupled receptors (GPR) bear the potential to serve as yet unidentified drug targets for psychiatric and metabolic disorders. GPR12 is of major interest given its putative role in metabolic function and its unique brain distribution, which suggests a role in emotionality and affect. We tested Gpr12 deficient mice in a series of metabolic and behavioural tests and subjected them to a well-established high-fat diet feeding protocol. Methodology/Principal Findings: Comparing the mutant mice with wild type littermates, no significant differences were seen in body weight, fatness or weight gain induced by a high-fat diet. The Gpr12 mutant mice displayed …

The Effects Of Antipsychotics On The Density Of Cannabinoid Receptors In The Dorsal Vagal Complex Of Rats: Implications For Olanzapine-Induced Weight Gain, Katrina Weston-Green, Xu-Feng Huang, Mei Han, Chao Deng Sep 2012

The Effects Of Antipsychotics On The Density Of Cannabinoid Receptors In The Dorsal Vagal Complex Of Rats: Implications For Olanzapine-Induced Weight Gain, Katrina Weston-Green, Xu-Feng Huang, Mei Han, Chao Deng

Xu-Feng Huang

Some atypical antipsychotics clinically used to treat schizophrenia induce weight gain by unknown mechanisms. The dorsal vagal complex (DVC) of the brainstem and the endogenous cannabinoid system are implicated in the regulation of appetite signalling and food intake. We investigated whether antipsychotic drugs alter cannabinoid receptor-binding density in the DVC. Female Sprague–Dawley rats were treated with olanzapine, haloperidol, aripiprazole or vehicle for 1 wk (short-term) or 12 wk (chronic). Quantitative autoradiographic methods were employed to investigate the binding density of cannabinoid receptors in the DVC using a highly sensitive Beta Imager. Short-term olanzapine induced a significant 39% decrease in cannabinoid …

Inter-Meal Interval Is Increased In Mice Fed A High Whey, As Opposed To Soy And Gluten, Protein Diets, Xu-Feng Huang, Timothy South, Yinghua Yu

Xu-Feng Huang

This study aimed to characterise meal patterns and satiety effects of diets that are high in protein but differ in protein source. Using a computerised automatic recording system, meal pattern behaviour was recorded continuously for 7 days in mice fed single (whey, soy or gluten) or different combined protein diets. Overall, average energy intake was significantly lower in mice fed a whey protein diet than those fed soy, gluten and lab chow diets. Among these four diets, the inter-meal interval of mice fed a whey protein diet was the longest and their meal number was the lowest. Combination of whey …

Decreased Density Of Serotonin 2a Receptors In The Superior Temporal Gyrus In Schizophrenia - A Postmortem Study, Xu-Feng Huang, Chao Deng, Qing Wang, Kai Kang

Xu-Feng Huang

The superior temporal gyrus (STG) is strongly implicated in the pathophysiology of schizophrenia,particularly with regards to auditory hallucinations. In this study, using in situ quantitative autoradiography in postmortem tissue, we investigated the binding of the [3H]ketanserin to 5-HT2A receptors and [3H] mesulergine to 5-HT2C receptors in the left STG of 8 male schizophrenic patients compared to 8 control subjects. A strong [3H]ketanserin binding was observed in the STG, however there was a very weak [3H] mesulergine binding in the STG. A significant decrease in binding of [3H]ketanserin was clearly observed in schizophrenia patients in comparison with control subjects. There were …

The Schizophrenia Susceptibility Gene Neuregulin 1 Modulates Tolerance To The Effects Of Canabinoids, Aurelie Boucher, Glenn E. Hunt, Jacques Micheau, Xu-Feng Huang, Iain Mcgregor, Tim Karl, Jonathon Arnold

Xu-Feng Huang

Cannabis increases the risk of schizophrenia in genetically vulnerable individuals. In this study we aim to show that the schizophrenia susceptibility gene neuregulin 1 (Nrg1) modulates the development of tolerance to cannabinoids in mice. Nrg1 heterozygous (HET) and wild-type (WT) mice were treated daily for 15 d with the synthetic analogue of D9-tetrahydrocannabinol, CP55,940 (0.4 mg/kg). We measured the impact of this exposure on locomotor activity, anxiety, prepulse inhibition (PPI), body temperature and FosB/DFosB immunohistochemistry. Tolerance to CP55,940-induced hypothermia and locomotor suppression developed more rapidly in Nrg1 HET mice than WT mice. Conversely in the light-dark test, while tolerance to …

Short- And Long-Term Effects Of Antipsychotic Drug Treatment On Weight Gain And H1 Receptor Expression, Kelly Newell, Xu-Feng Huang, Chao Deng, Tom Burne, Mei Han

Xu-Feng Huang

The present study investigated body weight gain, food intake, open-field activity and brain histamine H1 receptor mRNA and protein expression in rats treated with three types of antipsychotics. Rats were divided into eight groups and treated with aripiprazole (2.25mg/kg/day), olanzapine (1.5mg/kg/day), haloperidol (0.3mg/kg/day) or vehicle (as control) for 1 or 12 weeks. Administration of olanzapine for 1 week led to a threefold increase in body weight gain and a 35% increase in fat deposits compared to controls (p<0.05). In the 12-week olanzapine treatment group, accumulative food intake was significantly higher in the first 7 weeks of treatment compared to …
