Aging-induced type I interferon response at the choroid plexus negatively affects brain function.

ABSTRACT: We investigated gene expression profile of the Brain's choroid plexus and other organs of young and aged mice. Additionally, we analysed gene expression profile of the choroid plexus in iso- and heterochronic- parabiosis settings of young and aged mice. 75 samples

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

Choroid Plexus Gene Expression in ApoE3 or ApoE4-Knockin Mouse Choroid Plexuses

Project description:Laser capture microdissected choroid plexuses were obtained and expression arrays were generated to investigate gene expression in ApoE-Knockin choroid plexuses; the choroid plexus forms the cerebrospinal fluid, the cerebrospinal fliod barrier, functions as the major gateway for blood-born leukocytes to enter the brain in degenerative and inflammatory brain diseases, and the principal neuroimmune interface in the brain. We found lipid deposits in the aged choroid plexus of hyperlipidemic ApoE4-Knockin mice but none in normolipidemic ApoE4-Knockin or normolipidemic or hyperlipidemic ApoE3-Knockin control choroid plexuses. Here, we studied the functional impact and gene epressions these choroid plexuses.

Choroid Plexus Gene Expression in wild-type (wt) and ApoE-deficient Mouse Choroid Plexuses

Project description:Laser capture microdissected choroid plexuses were obtained and expression arrays were generated to investigate gene expression in wt and ApoE choroid plexuses; the choroid plexus forms the cerebrospinal fluid, the cerebrospinal fliod barrier, functions as the major gateway for blood-born leukocytes to enter the brain in degenerative and inflammatory brain diseases, and the principal neuroimmune interface in the brain. We found lipid deposits in the aged choroid plexus of hyperlipidemic mice but none in the wt control choroid plexuses. Here, we studied the functional impact and gene epressions in wt and ApoE-deficient choroid plexuses.

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.

Expression data from whole lateral ventricle choroid plexus tissue of young (two months old) and aged (eighteen months old) CD1 male mice.

Project description:We used microarrays to reveal the global expression profiles of young and old whole lateral ventricle choroid plexus tissue. RNA was isolated from whole lateral ventricle choroid plexus tissue followed by RNA amplification and hybridization on Affymetrix microarrays. Each sample contains both lateral ventricle choroid plexi from one male CD1 mouse. A total of six samples (three biological replicates from 2 different ages) were analyzed.
