Analysis of prefrontal cortex of Df(16)A/+ animals. Df(16)A/+ animals carry microdeletions of about 1.3Mb in the locus syntenic to human 22q11.2. Individuals with 22q11.2 microdeletions show behavioral and cognitive deficits and are at high risk of developing schizophrenia.

(Submitter supplied) Df16(A)+/- mice line is a model of human 22q11 microdeletion syndrome. We conducted an unbiased evaluation of the transcriptional difference in the prefrontal cortex and hippocampus areas between mutant and wild type animals at two early developmental stages (embryonic day 17 and postnatal day 6). These mice were generated by chromosomal engineering and carry a microdeltion of ~1.3Mb in the mouse locus syntenic to the human 22q11.1 The reasoning behind this expression profiling is that consistent alterations in transcriptional programs reflect either downstream (immediate or remote) effects of the deficiency or reactive (compensatory) changes, and can thus point to affected biological processes and molecular functions. more...

(Submitter supplied) We are using induced pluripotent stem cell (iPSC) technology to study neuropsychiatric disorders associated with 22q11.2 microdeletions (del), the most common known schizophrenia (SZ) -associated genetic factor. Several genes in the deleted region have been implicated; one of the more promising candidates is DGCR8, which codes for a protein involved in microRNA (miRNA) biogenesis. We carried out miRNA expression profiling (miRNA-seq) on neurons generated from iPSCs derived from controls and SZ patients with 22q11.2 del.

(Submitter supplied) Among the fundamental unresolved questions in psychiatry is why symptoms of psychosis, such as auditory hallucinations in schizophrenia, fail to appear until early adulthood. Here we report that in mouse models of 22q11.2 deletion syndrome (22q11DS), a leading genetic cause of schizophrenia, synaptic transmission at thalamocortical inputs to the auditory cortex becomes disrupted later in life, thereby recapitulating the adult onset of psychosis. more...

(Submitter supplied) Progressive ventricular enlargement is one of the most reproducible and recognizable structural abnormalities in schizophrenia, and is associated with more severe symptoms and poorer clinical outcome. The mechanisms of ventricular enlargement in schizophrenia is unknown. We identified that progressive ventricular enlargement is associated with deceleration of motile cilia beating in ependymal cells lining ventricular walls in murine models of schizophrenia-associated 22q11 deletion syndrome (22q11DS). more...

(Submitter supplied) Background: It has been found that miR-21 is increased in colonic tissues and decreased in peripheral blood regulatory T cells (Tregs) of patients with ulcerative colitis (UC). We aimed to investigate the influence of miR-21 on Tregs function in intestinal inflammation. Methods: Various CD4+ T cell populations were flow-cytometry sorted from miR-21-/- mice and littermates (WT) utilization in T-cell transfer colitis model and suppression of T cell activation and proliferation by Tregs. more...

(Submitter supplied) 22q11-deletion syndrome (22q11DS) is a developmental anomaly caused by a microdeletion on human chromosome 22q11. Although mouse models indicated Tbx1 as the gene responsible of the syndrome, the phenotypic spectrum of del22q11 patients is complex suggesting that gene-gene and gene-environment interactions, probably during embryonic development, are crucial in delineating the pathogenesis of 22q11DS. more...

(Submitter supplied) Canonical microRNAs (miRNAs) require two processing steps: the first by the Microprocessor, a complex of DGCR8 and Drosha, and the second by Dicer. dgcr8delta/delta mouse embryonic stem cells (mESCs) have less severe phenotypes than dicer1delta/delta mESCs, suggesting a physiological role for Microprocessor-independent, Dicer-dependent small RNAs. To identify these small RNAs with unusual biogenesis, we performed high-throughput sequencing from wild type, dgcr8delta/delta, and dicer1delta/delta mESCs. more...

(Submitter supplied) miR-132 and miR-212 are structurally-related microRNAs that have been found to exert powerful modulatory effects within the central nervous system (CNS). Notably, these microRNAs are tandomly processed from the same non-coding transcript, and share a common seed sequence: thus it has been difficult to assess the distinct contribution of each microRNA to gene expression within the CNS. Here, we employed a combination of conditional knockout and transgenic mouse models to examine the contribution of the miR-132/212 gene locus to learning and memory, and then to assess the distinct effects that each microRNA has on hippocampal gene expression. more...

(Submitter supplied) We intend to screen altered genes after overexpression of miR-196a in HD transgenic mice. Two transgenic mouse lines were used in this study, including HD transgenic mice and HD transgenic mice overexpressing miR-196a. The mice were all at approximate 12 months of age. At this point, HD transgenic mice showed severve motor dysfunctions, whereas HD transgenic mice overexpressing miR-196a displayed mild motor dysfunctions.

(Submitter supplied) Koolen-de Vries syndrome (KdVS) is a multi-system disorder characterized by intellectual disability, friendly behavior, and congenital malformations. The syndrome is caused either by microdeletions in the 17q21.31 chromosomal region or by variants in the KANSL1 gene. The reciprocal 17q21.31 microduplication syndrome is associated with psychomotor delay, and reduced social interaction. To investigate the pathophysiology of 17q21.31 microdeletion and microduplication syndromes, we generated three mouse models: 1) the deletion (Del/+); or 2) the reciprocal duplication (Dup/+) of the 17q21.31 syntenic region; and 3) a heterozygous Kansl1 (Kans1+/-) model. more...
