Project description:The study profiles genome-wide miRNA expression in blood from 15 early-onset SZ (EOS) cases and 15 healthy controls. A total of 1070 miRNAs were detected by the microarrays in our samples. We profiles miRNA expression in 15 schizophrenia samples and 15 healthy controls to explore the alteration of miRNAs in schizophrenia.
Project description:The study profiles genome-wide mRNA expression in blood from 18 early-onset SZ (EOS) cases and 12 healthy controls. A total of 1070 mRNAs were detected by the microarrays in our samples. 18 schizophrenia samples and 12 healthy controls were used to acquire blood expression profiles
Project description:Schizophrenia (SZ) and bipolar disorder (BD) are severe psychiatric conditions, with a lifetime prevalence of about 1%. Both disorders have a neurodevelopment component, with onset of symptoms occurring most frequently during late adolescence or early adulthood. Genetic findings indicate the existence of an overlap in genetic susceptibility across the disorders. These gene expression profiles were used to identify the molecular mechanisms that differentiate SZ and BP from healthy controls but also that distinguish both from healthy individuals. They were also used to expand an analysis from an experiment that searched molecular alterations in human induced pluripotent stem cells derived from fibroblasts from control subject and individual with schizophrenia and further differentiated to neuron to identify genes relevant for the development of schizophrenia (GSE62105). Brain tissue (frontal cortex) from 30 healthy controls, 29 bipolar disorder patients and 29 schizophrenia patients were analyzed. The reference is an in-house pool of RNA extracted from 15 human cell lines.

Project description:Genome-wide patterns of DNA methylation were quantified using the Illumina Infinium HumanMethylation450K BeadChip (“450K array”) in DNA samples isolated from blood for schizophrenia cases, first episode psychosis patients and controls. These samples were profiled as part of a wider study where they were meta-analysed with other cohorts.
Project description:The use of biospecimens sampled from patients with active symptomatic manifestation has been regarded as indispensable for studying pathophysiological mechanisms in many medical conditions, such as several types of cancers, liver disorders encompassing hepatitis, and lung disorders including idiopathic pulmonary fibrosis. However, due to the difficulty in accessing the brain in living patients, this strategy has not been utilized in psychiatry. To overcome this limitation, multiple investigators have recently highlighted the utility of olfactory epithelium-derived neuronal cells (henceforth, ‘olfactory neuronal cells’), easily accessible through a nasal biopsy, as a promising surrogate that captures neuron-relevant molecular signatures in the course of functional impairment in living patients with major psychiatric disorders. We analyzed gene expression profiles of olfactory neuronal cells from patients with schizophrenia compared to those from healthy controls. A microarray analysis identified significantly dysregulated genes in SZ
