Multivariable gene-set association suggested that common variation enrichment within biologically constrained genes observed for schizophrenia also occurs across several psychiatric phenotypes. Pairwise meta-analysis of schizophrenia and each psychiatric phenotype was implemented and identified 330 significantly associated genes (PMeta < 2.7 × 10−6) that were only nominally associated with each disorder individually (P < 0.05). These analyses consolidate the overlap between the genomic architecture of schizophrenia and other psychiatric disorders, uncovering several candidate pleiotropic genes which warrant further investigation.]]> Wed 26 Oct 2022 14:40:02 AEDT ]]> Effect of immune activation during early gestation or late gestation on inhibitory markers in adult male rats https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:45189 In situ hybridisation revealed that polyI:C offspring had: (1) SST mRNA reductions in the cingulate cortex and nucleus accumbens shell, regardless of MIA timing; (2) SSTR2 mRNA reductions in the cortex and striatum of GD19, but not GD10, MIA; (3) no alterations in cortical or striatal GAD1 mRNA of polyI:C offspring, but an expected reduction of PVALB mRNA in the infralimbic cortex, and; (4) no alterations in inhibitory markers in hippocampus. Maternal IL-6 response negatively correlated with adult offspring SST mRNA in cortex and striatum, but not hippocampus. These results show lasting inhibitory-related deficits in cortex and striatum in adult offspring from MIA. SST downregulation in specific cortical and striatal subregions, with additional deficits in somatostatin-related signalling through SSTR2, may contribute to some of the adult behavioural changes resulting from MIA and its timing.]]> Wed 26 Oct 2022 14:26:13 AEDT ]]> Epigenomic dysregulation in schizophrenia: in search of disease etiology and biomarkers https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:45103 Wed 26 Oct 2022 13:14:01 AEDT ]]> Differential effect of disease-associated ST8SIA2 haplotype on cerebral white matter diffusion properties in schizophrenia and healthy controls https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:34987 Wed 24 Nov 2021 15:52:45 AEDT ]]> Dietary intake of people with severe mental illness: systematic review and meta-analysis https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:35669 Wed 24 Nov 2021 15:51:43 AEDT ]]> The effect of maternal immune activation and adolescent cannabinoid exposure on behaviour, neurophysiology and cognition in a rodent model of schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:38769 Wed 20 Mar 2024 15:52:14 AEDT ]]> Interactive effects of polygenic risk and cognitive subtype on brain morphology in schizophrenia spectrum and bipolar disorders https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:51035 Wed 16 Aug 2023 10:17:09 AEST ]]> Cell type-specific manifestations of cortical thickness heterogeneity in schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:47091 Wed 14 Dec 2022 09:37:26 AEDT ]]> Electrophysiological, cognitive and clinical profiles of at-risk mental state: the longitudinal Minds in Transition (MinT) study https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:30417 Wed 11 Apr 2018 10:16:02 AEST ]]> Auditory prediction errors as individual biomarkers of schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:30677 p-values = 0.0326, FDR corrected) and an ROC analysis yielding an AUC of 0.87.

Methods: Using both univariate (voxel-based morphometry, VBM; cortical thickness) and multivariate (source-based morphometry, SBM) approaches, we examined the effects of variation of the rs1344706 polymorphism on grey matter integrity in 214 Caucasian schizophrenia cases and 94 Caucasian healthy individuals selected from the Australian Schizophrenia Research Bank. Results: Neither univariate nor multivariate analyses showed any associations between indices of grey matter and rs1344706 variation in schizophrenia or healthy participants. This was revealed in the context of the typical pattern of decreased grey matter integrity in schizophrenia compared to healthy individuals, including: (1) large grey matter volume reductions in the orbitofrontal and anterior cingulate cortices and the left fusiform/inferior temporal gyri; (2) decreased cortical thickness in the left inferior temporal and fusiform gyri, the left orbitofrontal gyrus, as well as in the right pars opercularis/precentral gyrus; and (3) decreased covariation of grey matter concentration in frontal and limbic brain regions emerging from the SBM analyses. Conclusions: Contrary to some – but not all – previous findings, this study of a large sample of schizophrenia cases and healthy controls reveals no evidence for association between grey matter alterations and variation in rs1344706 (ZNF804A). Differences in sample sizes and ethnicities may account for discrepant findings between the present and previous studies.]]> Wed 07 Jun 2023 14:36:02 AEST ]]> Men and women with psychosis and the impact of illness-duration on sex-differences: the second Australian national survey of psychosis https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:28028 Wed 04 Sep 2019 09:48:07 AEST ]]> Genetic correlation between amyotrophic lateral sclerosis and schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:34119 -4) with schizophrenia polygenic risk scores explaining up to 0.12% of the variance in ALS (P=8.4 × 10-7). A modest increase in comorbidity of ALS and schizophrenia is expected given these findings (odds ratio 1.08-1.26) but this would require very large studies to observe epidemiologically. We identify five potential novel ALS-associated loci using conditional false discovery rate analysis. It is likely that shared neurobiological mechanisms between these two disorders will engender novel hypotheses in future preclinical and clinical studies.]]> Wed 04 Sep 2019 09:40:14 AEST ]]> The Quality of Internet Websites for People Experiencing Psychosis: Pilot Expert Assessment https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:52173 Wed 04 Oct 2023 11:03:26 AEDT ]]> An active inference perspective on the negative symptoms of schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:49052 Wed 03 May 2023 15:47:20 AEST ]]> The "Double Whammy": Women's Experiences of Weight Gain After Diagnosis and Treatment for Schizophrenia Spectrum Disorders. https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:41435 Wed 03 Aug 2022 14:26:31 AEST ]]> The maternal immune activation model uncovers a role for the Arx gene in GABAergic dysfunction in schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:44959 Arx gene, critical to healthy neurodevelopment of PV interneurons, is reduced in the forebrain of MIA exposed mice. Finally, in a whole-genome sequenced patient cohort, we identified a novel missense mutation of ARX in a patient with schizophrenia and in the Psychiatric Genomics Consortium 2 cohort, a nominal association of proximal ARX SNPs with the disorder. This suggests MIA, as a risk factor for schizophrenia, may be influencing Arx expression to induce the GABAergic dysfunction seen in schizophrenia and that the ARX gene may play a role in the prenatal origins of schizophrenia pathophysiology.]]> Tue 25 Oct 2022 12:28:24 AEDT ]]> Complement genes contribute sex-biased vulnerability in diverse disorders https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:38872 1, whereas schizophrenia affects men with greater frequency and severity relative to women2. All three illnesses have their strongest common genetic associations in the major histocompatibility complex (MHC) locus, an association that in SLE and Sjögren’s syndrome has long been thought to arise from alleles of the human leukocyte antigen (HLA) genes at that locus3,4,5,6. Here we show that variation of the complement component 4 (C4) genes C4A and C4B, which are also at the MHC locus and have been linked to increased risk for schizophrenia7, generates 7-fold variation in risk for SLE and 16-fold variation in risk for Sjögren’s syndrome among individuals with common C4 genotypes, with C4A protecting more strongly than C4B in both illnesses. The same alleles that increase risk for schizophrenia greatly reduce risk for SLE and Sjögren’s syndrome. In all three illnesses, C4 alleles act more strongly in men than in women: common combinations of C4A and C4B generated 14-fold variation in risk for SLE, 31-fold variation in risk for Sjögren’s syndrome, and 1.7-fold variation in schizophrenia risk among men (versus 6-fold, 15-fold and 1.26-fold variation in risk among women, respectively). At a protein level, both C4 and its effector C3 were present at higher levels in cerebrospinal fluid and plasma8,9 in men than in women among adults aged between 20 and 50 years, corresponding to the ages of differential disease vulnerability. Sex differences in complement protein levels may help to explain the more potent effects of C4 alleles in men, women’s greater risk of SLE and Sjögren’s syndrome and men’s greater vulnerability to schizophrenia. These results implicate the complement system as a source of sexual dimorphism in vulnerability to diverse illnesses.]]> Tue 22 Feb 2022 16:36:25 AEDT ]]> Sex-Dependent Shared and Nonshared Genetic Architecture Across Mood and Psychotic Disorders https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:44746 Tue 21 Mar 2023 16:53:58 AEDT ]]> miRNA cargo in circulating vesicles from neurons is altered in individuals with schizophrenia and associated with severe disease https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:54330 Tue 20 Feb 2024 15:58:57 AEDT ]]> Estimation of Genetic Correlation via Linkage Disequilibrium Score Regression and Genomic Restricted Maximum Likelihood https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:44630 Tue 18 Oct 2022 12:11:18 AEDT ]]> Transcriptomic abnormalities in peripheral blood in bipolar disorder, and discrimination of the major psychoses https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:41878 Tue 16 Aug 2022 10:04:26 AEST ]]> Rare genome-wide copy number variation and expression of schizophrenia in 22q11.2 deletion syndrome https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:33797 Tue 15 Jan 2019 15:29:29 AEDT ]]> Detecting an intention to communicate from nonword sounds https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:43160 Tue 13 Sep 2022 15:35:25 AEST ]]> Why mismatch negativity continues to hold potential in probing altered brain function in schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:54261 Tue 13 Feb 2024 13:32:14 AEDT ]]> Schizophrenia-associated MicroRNA–Gene Interactions in the Dorsolateral Prefrontal Cortex https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:45935 Tue 08 Nov 2022 10:00:10 AEDT ]]> Cross-disorder analysis of schizophrenia and 19 immune-mediated diseases identifies shared genetic risk https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:46890 Tue 06 Dec 2022 12:02:52 AEDT ]]> Late gestation immune activation increases IBA1-positive immunoreactivity levels in the corpus callosum of adult rat offspring https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:33669 Iba1, Gfap, IL1-β and TNF-α mRNA levels in the cingulate cortex (CC) in adult offspring exposed to maternal immune activation. Prenatal exposure to immune activation had a significant main effect on microglial IBA1-positive immunoreactive material (IBA1+IRM) in the corpus callosum; post-hoc analyses identified a significant increase in GD19 offspring, but not GD10. No change in was observed in the CC. In contrast, maternal immune activation had a significant main effect on GFAP+IRM in the CC at GD19 (not GD10); post-hoc analyses only identified a strong trend towards increased GFAP+IRM in the GD19 offspring, with no white matter changes. This suggests late gestation maternal immune activation causes subtle alterations to microglia and astrocytes in the adult offspring.]]> Tue 04 Jun 2019 13:36:19 AEST ]]> Contribution of copy number variants to schizophrenia from a genome-wide study of 41,321 subjects https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:34283 −15), which persisted after excluding loci implicated in previous studies (OR = 1.07, P = 1.7 × 10−6).

These findings suggest that the MIR137 VNTR4 may impact neuroanatomical development that may, in turn, influence the expression of more severe cognitive symptoms in patients with schizophrenia.]]> Mon 21 Nov 2022 11:38:46 AEDT ]]> Developing and testing a new tool to investigate detection of "intention to communicate" in men and women with schizophrenia and mentally healthy controls, using behavioral and neuroimaging techniques https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:36121 Mon 20 Jul 2020 09:17:37 AEST ]]> Royal Australian and New Zealand College of Psychiatrists professional practice guidelines for the administration of electroconvulsive therapy https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:44569 Mon 17 Oct 2022 11:30:44 AEDT ]]> A polygenic resilience score moderates the genetic risk for schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:38229 Mon 16 Aug 2021 17:39:39 AEST ]]> Continuation of treatment with clozapine after an episode of neutropenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:46272 Mon 14 Nov 2022 15:14:08 AEDT ]]> Large-scale analysis of structural brain asymmetries in schizophrenia via the ENIGMA consortium https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:50977 Mon 14 Aug 2023 15:24:38 AEST ]]> Schizophrenia risk conferred by rare protein-truncating variants is conserved across diverse human populations https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:50972 Mon 14 Aug 2023 15:19:39 AEST ]]> Perceptions of causal attribution and attitudes to genetic testing among people with schizophrenia and their first-degree relatives https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:50953 Mon 14 Aug 2023 14:36:26 AEST ]]> Pairwise genetic meta-analyses between schizophrenia and substance dependence phenotypes reveals novel association signals with pharmacological significance https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:50935 Mon 14 Aug 2023 12:29:31 AEST ]]> Age at first birth in women is genetically associated with increased risk of schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:43035 Mon 12 Sep 2022 11:49:25 AEST ]]> Electrocardiographic abnormalities and psychotropic polypharmacy in schizophrenia and schizoaffective disorders https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:51593 Mon 11 Sep 2023 15:32:24 AEST ]]> Schizophrenia, Recovery, and Culture: The Need for an Indian Perspective https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:54759 Mon 11 Mar 2024 15:01:46 AEDT ]]> Cognitive Control System Gates Insula Processing of Affective Stimuli in Early Psychosis https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:52269 Mon 09 Oct 2023 09:56:28 AEDT ]]> White matter neuron biology and neuropathology in schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:35822 Mon 09 Dec 2019 16:39:38 AEDT ]]> A molecule-based genetic association approach implicates a range of voltage-gated calcium channels associated with schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:42814 Mon 05 Sep 2022 14:06:54 AEST ]]> Effects of immune activation during early or late gestation on schizophrenia-related behaviour in adult rat offspring https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:33142 Mon 03 Sep 2018 12:55:09 AEST ]]> Polygenic disruption of retinoid signalling in schizophrenia and a severe cognitive deficit subtype https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:48305 Mon 01 May 2023 15:23:00 AEST ]]> Circular RNA biogenesis is decreased in postmortem cortical gray matter in schizophrenia and may alter the bioavailability of associated miRNA https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:48732 Fri 31 Mar 2023 09:37:21 AEDT ]]> The effect of adjunctive mangosteen pericarp on cognition in people with schizophrenia: secondary analysis of a randomized controlled trial https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:45466 n = 114 participants with completed cognitive outcomes at follow up were included in this analysis. Using the Cogstate Brief Battery, the following cognitive outcomes were assessed: psychomotor function, attention, visual learning and memory (visual and working). Subgroup analyses investigated whether baseline clinical parameters (baseline cognitive functioning, illness severity and duration, depressive symptoms) moderated the relationship between mangosteen pericarp extract intervention and change in cognitive outcomes. Results: There were no significant between-group changes in any cognitive outcomes assessed. Subgroup analysis based on baseline cognition and clinical characteristics did not reveal any significant between-group difference in change. Conclusions: Mangosteen pericarp extract did not affect cognitive outcomes in people with schizophrenia. Further investigation regarding optimal dosing strategies for mangosteen interventions and the testing of additional cognitive domains may be warranted.]]> Fri 28 Oct 2022 14:45:19 AEDT ]]> Characterising transcriptional perturbations arising from altered expression of schizophrenia-associated microRNA https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:35646 Fri 27 Sep 2019 17:15:43 AEST ]]> Mapping genomic loci implicates genes and synaptic biology in schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:49672 Fri 26 May 2023 15:35:47 AEST ]]> Population-based identity-by-descent mapping combined with exome sequencing to detect rare risk variants for schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:42186 n = 3,473) by performing identity-by-descent (IBD) mapping followed by exome sequencing of individuals identified as sharing risk haplotypes to search for rare risk variants in coding regions. We identified 45 rare haplotypes (>1 cM) that were significantly more common in cases than controls. By exome sequencing 105 haplotype carriers, we investigated these haplotypes for functional coding variants that could be tested for association in independent GWAS samples. We identified one rare missense variant in PCNT but did not find statistical support for an association with schizophrenia in a replication analysis. However, IBD mapping can prioritize both individual samples and genomic regions for follow-up analysis but genome rather than exome sequencing may be more effective at detecting risk variants on rare haplotypes.]]> Fri 26 Aug 2022 10:49:17 AEST ]]> Genetic contributors to risk of schizophrenia in the presence of a 22q11.2 deletion https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:39019 Fri 22 Apr 2022 09:10:54 AEST ]]> Association of Schizophrenia Risk with Disordered Niacin Metabolism in an Indian Genome-wide Association Study https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:49494 Fri 19 May 2023 10:52:01 AEST ]]> Dysregulation of circRNA expression in the peripheral blood of individuals with schizophrenia and bipolar disorder https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:49352 Fri 12 May 2023 12:21:21 AEST ]]> Brain ageing in schizophrenia: evidence from 26 international cohorts via the ENIGMA Schizophrenia consortium https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:51559 Fri 08 Sep 2023 16:29:26 AEST ]]> Alteration of miRNA-mRNA interactions in lymphocytes of individuals with schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:37045 Fri 07 Aug 2020 14:34:14 AEST ]]> Interaction Testing and Polygenic Risk Scoring to Estimate the Association of Common Genetic Variants with Treatment Resistance in Schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:49142 Fri 05 May 2023 12:07:01 AEST ]]> Large-scale mapping of cortical alterations in 22q11.2 deletion syndrome: Convergence with idiopathic psychosis and effects of deletion size https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:41596 Fri 05 Aug 2022 14:58:18 AEST ]]> Polygenic risk for schizophrenia as a moderator of associations between childhood trauma and schizotypy https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:51364 Fri 01 Sep 2023 13:45:06 AEST ]]>
