The impact of schizophrenia genome wide association study genes on functional connectivity : a functional magnetic resonance imaging study
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Psychiatry, 2014)Genome-wide association studies (GWAS) have identified several genetic variants associated with increased schizophrenia risk. However, the specific mechanisms by which these variants increase risk are not fully understood. ... -
The impact of schizophrenia genome-wide association study genes on neurocognition and social cognition : a behavioural study
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Psychiatry, 2013)Genome wide association studies (GWAS) have established numerous previously unidentified variants associated with increased risk for schizophrenia (SZ). Exactly how most of these variants exert their influence remains ... -
The influence of Alzheimer's dementia on time spent caregiving for persons with Down Syndrome
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Psychiatry, 2003)Background: Persons with Down syndrome (DS) are at increased risk of Alzheimer’s type dementia (AD) when compared to the general population, yet little attention has been paid to the impact of the illness on such persons ... -
The neural basis of reward processing in Autism Spectrum Disorder : brain function, structure and connectivity
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Psychiatry, 2013)Autism spectrum disorder (ASD) is a pervasive developmental disorder defined by impairments in reciprocal social interaction and communication, as well as stereotyped behaviour and repetitive interests (Lord et al., 2011). ... -
Total and phosphorylated Tau protein as biological markers of Alzheimer's disease
(Elsevier, 2009)Advances in our understanding of tau-mediated neurodegeneration in Alzheimer?s disease (AD) are moving this disease pathway to center stage for the development of biomarkers and disease modifying drug discovery efforts. ... -
Transcriptome level analysis in Rett syndrome using human samples from different tissues
(BMC, 2018)The mechanisms of neuro-genetic disorders have been mostly investigated in the brain, however, for some pathologies, transcriptomic analysis in multiple tissues represent an opportunity and a challenge to understand the ... -
Transcriptomic analysis of Mecp2 mutant mice reveals differentially expressed genes and altered mechanisms in both blood and brain
(2019)Rett syndrome is a rare neuropsychiatric disorder with a wide symptomatology including impaired communication and movement, cardio-respiratory abnormalities, and seizures. The clinical presentation is typically associated ... -
Two patients walk into a clinic...a genomics perspective on the future of schizophrenia.
(BioMed Central, 2011)Progress is being made in schizophrenia genomics, suggesting that this complex brain disorder involves rare, moderate to high-risk mutations and the cumulative impact of small genetic effects, coupled with environmental ... -
Unlocking the treasure trove: From genes to schizophrenia biology
(2014)Significant progress is being made in defining the genetic etiology of schizophrenia. As the list of implicated genes grows, parallel developments in gene editing technology provide new methods to investigate gene function ... -
Use of codeine-containing medicines by Irish psychiatric in-patients before and after regulatory limitations on their supply.
(2013)Background. In recent years, concerns have been highlighted in several jurisdictions, including Ireland, regarding abuse of over-the-counter codeine-containing medicines. On the 1st of August 2010, national regulatory ... -
Using genome-wide complex trait analysis to quantify 'missing heritability' in Parkinson's disease.
(2012)Genome-wide association studies (GWASs) have been successful at identifying single-nucleotide polymorphisms (SNPs) highly associated with common traits; however, a great deal of the heritable variation associated with ... -
Variability in working memory performance explained by epistasis vs polygenic scores in the ZNF804A pathway.
(2014)IMPORTANCE We investigated the variation in neuropsychological function explained by risk alleles at the psychosis susceptibility gene ZNF804A and its interacting partners using single nucleotide polymorphisms (SNPs), ... -
The Wellcome trust UK-Irish bipolar affective disorder sibling-pair genome screen: first stage report
(Nature Publishing Group, 2002)We have completed the first stage of a two-stage genome wide screen designed to identify chromosomal regions that may harbour susceptibility genes for bipolar affective disorder. The first stage screening sample included ... -
What have the genomics ever done for the psychoses?
(2010)Background: Despite the substantial heritability of the psychoses and their genuine public health burden, the applicability of the genomic approach in psychiatry has been strongly questioned or prematurely dismissed.Method ... -
White matter microstructure underlying default mode network connectivity in the human brain
(2010)Resting state functional magnetic resonance imaging (fMRI) reveals a distinct network of correlated brain function representing a default mode state of the human brain. The underlying structural basis of this functional ... -
Whole genome linkage scan of recurrent depressive disorder from the depression network study
(Oxford University Press, 2005)Genome-wide linkage analysis was carried out in a sample of 497 sib pairs concordant for recurrent major depressive disorder (MDD). There was suggestive evidence for linkage on chromosome 1p36 where the LOD score for ... -
An X11[alpha]/FSBP complex represses transcription of the GSK3[beta] gene promoter.
(2010)X11? is a neuronal adaptor protein that interacts with the amyloid precursor protein (APP) via a centrally located phosphotyrosine binding (PTB) domain to inhibit production of A? peptide that is deposited in Alzheimer's ... -
X11beta rescues memory and long-term potentiation deficits in Alzheimer's disease APPswe Tg2576 mice.
(2009)Increased production and deposition of amyloid ?-protein (A?) are believed to be key pathogenic events in Alzheimer?s disease. As such, routes for lowering cerebral A? levels represent potential therapeutic targets for ...
