Human Choroid Plexus Single Nucleus RNA Sequencing Data [snRNA-Seq]

ABSTRACT: This study presents single-nucleus RNA sequencing data generated from postmortem human choroid plexus tissue. Isolated nuclei were profiled using the 10x Genomics Chromium platform to characterize gene expression across diverse cell populations of the choroid plexus. The resulting dataset provides a resource for investigating cell-type-specific transcriptional programs and cellular heterogeneity within the human choroid plexus in health and disease.

Spatial Transcriptomics Data from Human Choroid Plexus

Project description:This study presents spatial transcriptomic data generated from postmortem human choroid plexus tissue. Spatially resolved gene expression profiles were obtained using the Curio Bioscience Seeker v1.1 platform, enabling in situ transcript capture across intact tissue sections. This dataset provides a resource for investigating spatial organization, cellular heterogeneity, and regional transcriptional programs within the human choroid plexus.

Gene expression data from normal mouse choroid plexus, choroid plexus papilloma and choroid plexus carcinoma

Project description:Atoh1-Cre; Myc/Myc mice developed choroid plexus papilloma and Atoh1-Cre; Myc/Myc; p53fl/fl mice developed choroid plexus carcinoma. By studying the gene expression profiles of normal choroid plexus, choroid plexus papilloma and choroid plexus carcinoma in mice, we aim to gain a better understanding of the biology of choroid plexus tumors

Single Nucleus RNAseq dissection of choroid plexus tumor cell heterogeneity

Project description:To examine the cellular and transcriptional heterogeneity of choroid plexus tumors we determined the single nucleus transcriptomes of 23,906 nuclei from normal choroid plexus and choroid plexus tumors. The resulting cellular atlas profiles cellular and transcriptional heterogeneity, copy number alterations, and cell-cell interaction networks in normal and cancerous choroid plexus. We observe changes in choroid plexus tumor epithelial cell gene transcription that correlate with genome wide methylation profiles. In addition, we characterize tumor-grade-specific tumor microenvironments that include altered macrophage and mesenchymal cell states, as well as changes in extracellular matrix components.

Choroid Plexus-Derived Insulin Inhibits Feeding via Direct Signaling through Arcuate Nucleus

Project description:The choroid plexus is an important source of trophic factors for the developing and mature brain. Recently we described the expression and production of mature insulin in epithelial cells of the choroid plexus, and how its secretion can be modulated by serotonin through Htr2c, a metabotropic receptor that signals via Gq. To understand the function of this choroid plexus-derived insulin, here we describe a way to genetically target epithelial cells of the choroid plexus using a viral vector. With this, we modulated insulin expression and evaluated behavior. Insulin overexpression in the choroid plexus of wild type mice led to an inhibition in feeding, whereas insulin knockdown in choroid plexus of Ins1-/-Ins2fl/fl mice promoted discrete increases in food intake, especially after a period of fasting. Insulin overexpression in choroid plexus induced roust transcriptomic changes in the hypothalamus, most of which related to axonal growth and synapse-related processes. Finally, activation of Gq signaling in insulin-overexpressing choroid plexuses led to acute AKT phosphorylation in neurons of the arcuate nucleus, suggesting a direct action, through the CSF, of choroid plexus-derived insulin on the hypothalamus. Taken together our findings prove that the choroid plexus is a relevant source of insulin in the central nervous system, with physiological implications in feeding behavior. We believe that choroid plexus-derived insulin has to be taken into consideration in future work pertaining insulin actions in the brain.

Gene expression profiles obtained from laser-microdissected human choroid plexus papilloma cells

Project description:Gene expression profiles generated from human tumor cells laser-microdissected from surgical samples of seven choroid plexus papillomas (Grade I WHO) as eight samples of epithelial cells lasermicrodissected from normal choroid plexus obtained at autopsy. Choroid plexus tumors are rare pediatric brain tumors derrived from the choroid plexus epithelium. Gene expression profiles of lasermicrodissected tumor cells from 7 individual choroid plexus tumor samples obtained at surgery were compared to gene expression profiles from non-neoplastic choroid plexus epithelial cells lasermicrodissected from normal non-neoplastic choroid plexus obtained at autopsy (Am J Surg Pathol. 2006 Jan;30(1):66-74.) in order to identfy genes differentially expressed in choroid plexus tumor cells.

OTX2 homeoprotein regulates adult choroid plexus activity

Project description:Choroid plexus secretes cerebrospinal fluid important for brain development and homeostasis. The OTX2 homeoprotein is critical for choroid plexus development and remains highly expressed in adult choroid plexus. Through RNA sequencing analyses of constitutive and conditional knockdown adult mouse models, we reveal putative roles for OTX2 in choroid plexus function, including cell signaling and adhesion, and show that it regulates the expression of factors secreted into cerebrospinal fluid, notably transthyretin. We also show that Otx2 expression impacts choroid plexus immune and stress responses, and also affects splicing which leads to changes in mRNA isoforms of proteins implicated in oxidative stress response and DNA repair. Through mass spectrometry analysis of OTX2 protein partners in the choroid plexus, and in known non-cell autonomous target regions such as visual cortex and subventricular zone, we identified putative targets involved in cell adhesion, chromatin structure and RNA processing. Thus, OTX2 retains important roles in choroid plexus function and brain homeostasis throughout life.

Proteomics profiling of pediatric choroid plexus tumors

Project description:Aggresome is a para nuclear inclusion body that functions as a storage compartment for misfolded proteins. Our previous work revealed the presence of aggresomes in pediatric choroid plexus tumors (CPT). CPTs are rare neoplasms comprised of three pathological subgroups; choroid plexus carcinoma (CPC), a grade III tumor, atypical choroid plexus papilloma (ACPP), a grade II tumor, and choroid plexus papilloma (CPP), a grade I tumor. In the current study, we aimed to investigate the prognostic value of aggresomes-positivity and its correlation to the pathological and molecular subtypes. The proteomics profiling of 21 CPT pediatric samples was investigated using ABSciex Triple TOF 5600+ mass spectrometer.
