Exploring PDE5A upregulation in bipolar disorder: insights from single-nuclei RNA sequencing of human basal ganglia

ABSTRACT: The basal ganglia has been considered as a potential target implicated in bipolar disorder (BD), but there is currently limited research on molecular changes. In this study, we conducted single-nucleus RNA sequencing on 30,752 nuclei from the putamen, caudate nucleus, pallidum, and substantia nigra of postmortem brains without apparent neurological and psychiatric disorders, as well as 24,672 nuclei from the same brain regions of BD patients. By performing differential expression analysis, weighted gene co-expression network analysis (WGCNA), single-cell regulome analysis (SCENIC), and CellChat analysis, we investigated the cell type-specific gene expression and network changes in the basal ganglia of BD patients compared to healthy individuals. These findings provide an important direction for the study of bipolar disorder.

Transcriptional characterization of mouse and rat ventral pallidum using single nucleus RNA-sequencing

Project description:The ventral pallidum (VP) was defined as a basal ganglia nucleus and a major output of the nucleus accumbens. It is known to be involved in motivated behaviors, including feeding. We sought to further characterize VP by sequencing the RNA from individual nuclei in mouse and rat VP and analyzing neuronal expression patterns. We also investigated the impact of a high-fat diet on VP transcription. These data will be useful for understanding cell type diversity in VP, homology between mouse and rat VP, and the impact of diet on VP gene expression.

Transcriptome profiling of the human dorsal striatum in bipolar disorder

Project description:Bipolar disorder (BD) is a highly heritable and heterogeneous mental illness whose manifestations often include impulsive and risk-taking behavior. This particular phenotype suggests that abnormal striatal function could be involved in BD etiology, yet most transcriptomic studies of this disorder have concentrated on cortical brain regions. We report the first transcriptome profiling by RNA-Seq of the human dorsal striatum comparing bipolar and control subjects. Differential expression analysis and functional pathway enrichment analysis were performed to identify changes in gene expression that correlate with BD status. Further co-expression and enrichment analyses were performed to identify sets of correlated genes that show association to BD. Total RNA samples were isolated from 36 postmortem dorsal striatum subjects (18 bipolar and 18 control) and sequenced. One outlier sample was removed and 35 samples (18 bipolar and 17 control) were analyzed.

Knockdown of TSPAN8 gene expression in the SH-SY5Y neuroblastoma cell line

Project description:Bipolar disorder (BD) has an estimated heritability of about 80%. Different pathways and candidate genes may contribute to the pathogenesis of BD, but definite mechanisms are yet unresolved. In a previous study, we identified the single nucleotide polymorphism (SNP) rs4500567, located in the upstream region of Tetraspanin 8 (TSPAN8), to be associated with bipolar disorder (BD). The SNP´s minor allele results in a predicted binding site for the transcription factor Nuclear Factor Interleukin 3, regulated (NFIL3); luciferase assays confirmed allele-specific TSPAN8 expression levels.

Transcriptional profiling of monocytes of bipolar patients and controls

Project description:Bipolar disorder (BD) is a psychiatric disorder in which the core feature is pathological disturbance in mood ranging from extreme elation (mania) to severe depression. Study has shown an aberrant pro-inflammatory status of monocytes/macrophages in mood disorders. Therefore, this study aimed at studying the monocyte compartment in Bipolar Disorder, by transcription profiling of CD14+ monocytes in patients and controls.

Promoter-wide profiling of DNA hydroxymethylation in prefrontal cortex of healthy controls

Project description:Bipolar disorder (BD) is a severe mental disorder characterized by repeated mood swings. Although genetic factors with small effect sizes are collectively associated with the pathophysiology of BD, the underlying molecular mechanisms, especially how environmental factors affect the brain genome, remain largely unknown. We revealed neuronal cell-type-specific, pathophysiology-related DNA methylation changes in the prefrontal cortex (PFC) of BD patients, highlighting the importance of the neural epigenome for understanding BD.
