CELSR3 deficiency leads to tic-related behaviors and dopaminergic alterations in the striatum

ABSTRACT: The gene CELSR3 (cadherin EGF LAG seven‐pass-G‐type receptor 3) has been recently recognized as a high-confidence risk factor for tic disorders (TD). Celsr3 mutant mice displayed tic-like grooming stereotypies and jerks, as well as sensorimotor gating deficits, which were opposed by TD therapies. Single-nucleus transcriptomic analyses revealed that Celsr3 mutants featured a unique group of eccentric striatal projection neurons. Notably, the Drd3 gene, encoding the dopamine D3 receptor, was significantly upregulated in these cells as well as striosomal D1-positive neurons, while it was reduced in calretinin-positive GABAergic interneurons.

Spatial component of: CELSR3 deficiency leads to tic-related behaviors and dopaminergic alterations in the striatum

Project description:The gene CELSR3 (cadherin EGF LAG seven‐pass-G‐type receptor 3) has been recently recognized as a high-confidence risk factor for tic disorders (TD). Celsr3 mutant mice displayed tic-like grooming stereotypies and jerks, as well as sensorimotor gating deficits, which were opposed by TD therapies. Spatial transcriptomic analyses revealed that Celsr3 mutants featured abnormalities of the extracellular matrix in the striatum. Notably, there are alterations in collagen and extracellular organization.

Expression data from highly purified MMTV-Neu Tumor Initiating Cells (TICs) and the non-TIC CD24- fraction

Project description:The cancer stem cell model maintains that tumors are organized in a hierarchy driven by tumor initiating cells (TICs), and that patient survival inversely correlates with TIC gene expression. Here we generated a prognostic signature for HER2+ breast cancer from TICs purified from MMTV-Her2/Neu mammary tumors. TICs from this model, identified as Lin-:CD24+:JAG1- at a frequency of 2-5% by serial and single cell transplantation assays, showed elevated expression of proliferation genes and low expression of differentiation genes (compared to non-TIC fraction CD24- of the same tumor). We used microarrays to detect differentially expressed genes in the TIC fraction compared to the non-TIC fraction of the same tumor Cells from each primary tumor were separated by FACS into TIC and non-TIC fractions and total RNA was extracted and hybridized on Affymetrix microarrays.

Gut Microbiota from Human Autism Spectrum Disorder Induces Behavioral Deficits in Mice

Project description:We transplanted gut microbiota via fecal transfer from TD and ASD children into germ-free wild-type mice, and reveal that colonization with ASD microbiomes induces hallmark changes in sociability, vocalization, and stereotypies. The brains of mice receiving gut microbiota from ASD individuals display alternative splicing patterns for genes dysregulated in the human ASD brain.

Micro-RNAs from Plasma-Derived Small Extracellular Vesicles as Potential Biomarkers for Tic Disorders Diagnosis

Project description:tic disorders (TDs) are a series of childhood neuropsychiatric disorders characterized by invol-untary motor and/or vocal tics and commonly comorbid with several other psychopathological and/or behavioral disorders. In the present study, we aimed to identify serum small extracellular vesicles (sEVs) derived microRNAs (miRNAs) from the serum samples of children for Tic Disorders Diagnosis

The chloroplast outer and inner envelope membrane translocase (TOC/TIC) interaction network identifies a 23 kDa glycine-rich protein as new subunit of the 1-MDa TIC complex

Project description:The protein import machinery is essential for chloroplast biogenesis, but knowledge on its exact functioning and the subunits involved in protein translocation is incomplete. Using TAP-tagged Toc159, we reproducibly identified a translocase interaction network that comprises in addition to known TOC members, the 1-MDa TIC complex, six FtsH/FtsHi proteases, Tic110, the KOC1 kinase and several other proteins, some of which with unknown function. The analysis of sub-complexes constituting the Toc159 interaction network in wildtype and a mutant defective in the 1-MDa TIC complex (tic56-3) revealed that the TOC and FtsH/FtsHi complex(es) accumulate independently of the TIC complex as do most other proteins in the network. An exception is a glycine-rich protein of 23 kDa that co-migrates with the 1-MDa complex and is co-regulated with its subunits in tic56-3. This protein was tentatively designated as Tic23. Tic23 abundance is significantly decreased in tic20-I mutant plants and the protein is completely absent from tic56-1 and Spectinomycin-treated wildtype plants lacking Tic214, suggesting a mutual dependency between its accumulation and intactness of the 1-MDa complex. Likewise, tic23-I mutants expressing reduced levels of Tic23 are pale-green and accumulate significantly decreased amounts of Tic20-I. Similar to tic56-3 plastids, the in vitro protein import capacity of tic23-I mutants is not affected. Taken together our results identify Tic23 as an additional component of the 1-MDa TIC complex that is required for complex stability and assembly while it serves complex-mediated functions other than protein import.

Consequences of loss of spinophilin on striatal mGluR5 phosphorylation and interactome

Project description:Constitutive knockout of the obsessive-compulsive disorder-associated protein, SAPAP3, results in repetitive motor dysfunction, such as excessive grooming, caused by increased mGluR5 activity in striatal medium spiny neurons (MSNs). However, signaling mechanisms that mediate mGluR5-dependent grooming dysfunction are not fully understood. Here, we investigate the function of the striatal signaling hub protein, spinophilin, in regulating mGluR5 phosphorylation and protein interactions, which may predict spinophilin’s role in regulating mGluR5-dependent grooming dysfunction.
