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
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
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 …

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 …

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 …

This study examined changes in neuropeptide Y (NPY) Y2 receptor binding in the brains of C57BL/6 mice in response to different levels of high-fat diets via three dietary intervention methods: high-fat diet, switching from high- to low-fat diet and finally, energy restricted high-fat diet. Forty-five C57Bl/6 male mice were fed a high-fat diet for 8 weeks and then classified as diet-induced obese (DIO) or diet-resistant (DR) mice according to the highest and lowest body weight gainers, respectively. The DIO and DR mice were then randomly divided into three groups each and either continued on their high-fat diet ad libitum (DIO-H …

A Link Between Chronic Sleep Restriction And Obesity: Methodological Considerations, Christopher Magee, Donald Iverson, Xu-Feng Huang, Peter Caputi
Xu-Feng Huang
Emerging evidence suggests that chronicsleeprestriction contributes to obesity. Targeting short sleep duration may therefore offer a novel and effective method of preventing and treating obesity. However, this area of research is only in its infancy, and a complete understanding of how chronicsleeprestriction and obesity are linked is currently lacking. The aim of this paper is to briefly review epidemiological evidence for an association between chronicsleeprestriction and obesity in adults, and outline the key methodological limitations of these studies. Particular attention is paid to the methods used to measure sleep and obesity, as well as the need to control for potential …

Background and aims: Decreasing energy intake relative to energy expenditure is the indisputable tenet of weight loss. In addition to caloric restriction modification of the type of dietary fat may provide further benefits. The aim of the present study was to examine the effect of energy restriction alone and with dietary fat modification on weight loss and adiposity, as well as on risk factors for obesity related disease. Methods and results: One-hundred and fifty overweight men and women were randomized into a 3 month controlled trial with four low fat (30% energy) dietary arms: (1) isocaloric (LF); (2) isocaloric with …

Preventing obesity could be done by lowering plasma TAG that inhibits adipogenesis. Oat and mushroom beta-glucans in the diet has been reported to lower plasma lipid; however the data focusing on their effects on TAG and obesity are insufficient. In the present study, lowering plasma triacylglycerol, fat deposition, body weight gain (BWG) in rats fed a high fat diet (HFD) was evaluated. Rats in the control group were given HFD only and rats in the treatment group fed HFD enriched with 0.2%, 0.6% and 1.8% (wt:wt) beta-glucan from oats (LD-O, MD-O, HD-O) or mushroom (LD-M, MD-M, HD-M). After 6 weeks …

Cannabis contains over 70 unique compounds and its abuse is linked to an increased risk of developing schizophrenia. The behavioural profiles of the psychotropic cannabis constituent Δ9-tetrahydrocannabinol (Δ9-THC) and the non-psychotomimetic constituent cannabidiol (CBD) were investigated with a battery of behavioural tests relevant to anxiety and positive, negative and cognitive symptoms of schizophrenia. Male adult C57BL/6JArc mice were given 21 daily intraperitoneal injections of vehicle, Δ9-THC (0.3, 1, 3 or 10 mg/kg) or CBD (1, 5, 10 or 50 mg/kg). Δ9-THC produced the classic cannabinoid CB1 receptor-mediated tetrad of hypolocomotion, analgesia, catalepsy and hypothermia while CBD had modest hyperthermic effects. …

This study examined the effects of different food sources of protein on energy intake, body weight maintenance, and on the responses of plasma leptin, insulin and adiponectin in chronic high-fat diet-induced obese mice. Obesity was induced in 47 mice with a high-fat diet for 20 weeks. They were divided into five diet groups to test the effects of a higher protein proportion (30% energy), achieved at the expense of carbohydrate. For the next eight weeks, four of the groups were fed diets of chow formulated with whey, soy, red meat or milk while the control group continued on their high-fat …

Objective: In recent years, abnormal changes in the endocannabinoid system have been found in schizophrenia. The superior temporal gyrus (STG) is strongly implicated in the pathophysiology of schizophrenia, particularly with regards to auditory hallucinations. In this study, we investigated the binding density of cannabinoid CB1 receptors in the STG of schizophrenia patients compared to control subjects. Methods: Quantitative autoradiography was used to investigate the binding densities of [3H] SR141716A (a selective antagonist) and [3H]CP-55940 (an agonist) to the CB1 receptors in the STG. Post-mortem brain tissue was obtained from the NSW Tissue Resource Centre (Australia). Results: Contrasting to previous findings …

Statins are increasingly being used for the treatment of a variety of conditions beyond their original indication for cholesterol lowering. We previously reported that simvastatin affected the dopaminergic system in the rat brain. This study aims to investigate regional changes of muscarinic M1/4 receptors in the rat brain after 4-week administration of simvastatin (1 or 10 mg/kg/day). M1/4 receptor distribution and alterations in the post-mortem rat brain were detected by [3H]pirenzepine binding autoradiography. Simvastatin (1 mg/kg/day) increased [3H]pirenzepine binding, predominantly in the prefrontal cortex (171%, P<0.001), primary motor cortex (153%, P=0.001), cingulate cortex (109%, P<0.001), hippocampus (138%, P …

An Investigation Of The Dimensionality Of The Pittsburgh Sleep Quality Index In Australian Adults, Christopher Magee, Peter Caputi, Donald Iverson, Xu-Feng Huang
Xu-Feng Huang
The Pittsburgh Sleep Quality Index (PSQI) is widely used to assess subjective sleep quality in clinical and non-clinical settings. Although the PSQI is routinely scored to provide a single sleep quality factor, two recent studies suggest that multiple factor scoring methods could be more appropriate. As a consequence, the present study investigated for the dimensionality and factor structure of the PSQI in 364 Australian adults aged 18 to 59 years. The results demonstrate that two factor and three factor scoring models were favored statistically over the single factor model. These results add to recent findings and suggest that scoring the …

Aripiprazole Differentially Affects Mesolimbic And Nigrostriatal Dopaminergic Transmission: Implications For Long-Term Drug Efficacy And Low Extrapyramidal Side-Effects, Xu-Feng Huang, Chao Deng, Mei Han
Xu-Feng Huang
Aripiprazole has been used effectively to treat schizophrenia in the clinic ; however, its mechanisms ofaction are not clear. This study examined how short- and long-term aripiprazole treatment affects dopaminergic transmission in mesolimbic and nigrostriatal pathways. For comparison, the effects of haloperidol and olanzapine treatment were also examined. Aripiprazole significantly increased D2 receptor mRNA expression and decreased tyrosine hydroxylase (TH) mRNA expression in the ventral tegmental area (VTA) after 1- and 12-wk treatment, but had no effect in substantia nigra (SN) and nucleus accumbens (NAc). Aripiprazole also decreased dopamine transporter (DAT) binding density in NAc (for 1- and 12- wk …
