Members of the SR family of pre-mRNA splicing factors are phosphoproteins that share a phosphoepitope specifically recognized by monoclonal antibody (mAb) 104. Recent studies have indicated that phosphorylation may regulate the activity and the intracellular localization of these splicing factors. Here, we report the purification and kinetic properties of(More)
The molecular factors involved in the development of Post-Traumatic Stress Disorder (PTSD) remain poorly understood. Previous transcriptomic studies investigating the mechanisms of PTSD apply targeted approaches to identify individual genes under a cross-sectional framework lack a holistic view of the behaviours and properties of these genes at the(More)
We report striking differences in the substrate specificities of two human SR proteins, SF2/ASF and SC35, in constitutive splicing. beta-Globin pre-mRNA (exons 1 and 2) is spliced indiscriminately with either SR protein. Human immunodeficiency virus tat pre-mRNA (exons 2 and 3) and immunoglobulin mu-chain (IgM) pre-mRNA (exons C3 and C4) are preferentially(More)
Pre-mRNA splicing requires a large number of RNA-binding proteins that have one or more RNA-recognition motifs (RRMs). Among these is the SR protein family, whose members are essential for splicing and are able to commit pre-mRNAs to the splicing pathway with overlapping but distinct substrate specificity. Some SR proteins, such as SC35, contain an(More)
OBJECTIVE: Transcriptomic biomarkers of psychiatric diseases obtained from a query of peripheral tissues that are clinically accessible (e.g., blood cells instead of post-mortem brain tissue) have substantial practical appeal to discern the molecular subtypes of common complex diseases such as major psychosis. To this end, spliceome-profiling is a new(More)
OBJECTIVE Autism spectrum disorders (ASDs) are highly heritable neurodevelopmental disorders that onset clinically during the first years of life. ASD risk biomarkers expressed early in life could significantly impact diagnosis and treatment, but no transcriptome-wide biomarker classifiers derived from fresh blood samples from children with autism have yet(More)
Susceptibility to PTSD is determined by both genes and environment. Similarly, gene-expression levels in peripheral blood are influenced by both genes and environment, and expression levels of many genes show good correspondence between peripheral blood and brain. Therefore, our objectives were to test the following hypotheses: (1) pre-trauma expression(More)
Schizophrenia (SCZ) and bipolar disorder (BPD) are polygenic disorders with many genes contributing to their etiologies. The aim of this investigation was to search for dysregulated molecular and cellular pathways for these disorders as well as psychosis. We conducted a blood-based microarray investigation in two independent samples with SCZ and BPD from(More)
The Virtual Table presents stereoscopic graphics to a user in a workbench-like setting. For this device a user interface and new interaction techniques had been developed based on transparent props {a tracked hand-held pen and a pad 12. These props, but in particular the pad, are augmented with 3D graphics from the Virtual Table's display that can serve as(More)
Genes in the Wnt (wingless)/ β -catenin signaling pathway have been implicated in schizophrenia pathogenesis. No study has examined this pathway in the broader context of psychosis symptom severity. We investigated the association between symptom severity scores and expression of 25 Wnt pathway genes in blood from 19 psychotic patients. Significant(More)
