The microRNA cluster miR-183/96/182 contributes to long-term memory in a protein phosphatase 1 dependent manner

Project description:Memory formation is a complex cognitive function regulated by coordinated synaptic and nuclear processes in neurons. In mammals, it is controlled by multiple molecular activators and suppressors, including the key signaling regulator protein phosphatase 1 (PP1). Here, we show that memory control by PP1 involves the miR-183/96/182 cluster, which is selectively regulated during memory formation. Inhibiting nuclear PP1 in mice brain or training in object recognition task similarly increases miR-183/96/182 expression in the hippocampus. Mimicking this increase by overexpressing miR-183/96/182 enhances object memory, while suppressing endogenous level of the cluster reduces it. This effect involves the modulation of many plasticity-related genes, and we identified HDAC9 as one of the functional targets. Further, PP1 controls miR-183/96/182 in a transcription-independent manner influencing processing of their precursors. These findings provide novel evidence for the role of miRNAs in memory formation and suggest the implication of PP1 in miRNAs processing in the adult brain.

The miR-183/96/182 Cluster Regulates Sensory Innervation, Resident Myeloid Cells and Functions of the Cornea Through Cell type-specific Target Genes

Project description:The miR-183/96/182 cluster (miR-183C) is specifically expressed in sensory neurons and immune cells and modulates corneal immune/inflammatory response to bacterial infection. To uncover the roles of miR-183C in corneal homeostasis through its regulation of sensory neurons of the trigeminal ganglia (TG) and innate myeloid cells, we created miR-183C conventional knockout (KO), and sensory nerve-specific (SNS-CKO) and myeloid cell-specific conditional knockout (MS-CKO) mice. We performed 3'RNA sequencing in the TG and corneas of these knockout mice and their wild type (WT)-control littermates. To study specific functions of miR-183C in corneal resident myeloid cells (CRMCs), we isolated Csf1r-EGFP+ CRMCs from conventional KO and MS-CKO and their WT control mice. By comparison of the gene expression profiles of the KO or CKO vs their corresponding WT mice, we identified a series of differentially expressed genes. Bioinformatic analyses uncovered tissue- and/or cell-type-specific target genes of miR-183C. Functional annotation of the target genes revealed functions of miR-183C in TG and CRMCs.

Regulation of Th17 cell pathogenic function by miR-183/96/182

Project description:Th17 cells are key players in autoimmune diseases. However, the roles of non-coding RNAs in Th17 cells are largely unknown. Here, we show that deletion of the Dicer gene specifically in Th17 cells protects from experimental autoimmune encephalomyelitis (EAE). Th17 cells highly express the miR-183/96/182 cluster (miR-183C), in response to IL-6/STAT3 signaling. Moreover, miR-183C regulates pathogenic cytokine expression during Th17 development. Furthermore, transcription factor Foxo1 is one of functional targets of miR-183C in Th17 cells: Foxo1 negatively regulates the pathogenicity of Th17 cells and miR-183C represses Foxo1 expression. Collectively, our results demonstrate one of crucial roles for miR-183C cluster in regulation of Th17 cell function in autoimmune diseases.

A mouse model of miR-96, miR-182 and miR-183 misexpression implicates miRNAs in cochlear cell fate and homeostasis

Project description:Transgenic FVB/NCrl-Tg(GFAP-Mir183,Mir96,Mir182)MDW1 mice (Tg1MDW) overexpress this neurosensory-specific miRNA cluster in the inner ear and were developed as a model system to identify target genes and biologic processes regulated by the miR-183 cluster. Affymetrix mRNA microarray data analysis revealed that downregulated genes in P5 Tg1MDW/1MDW cochlea are statistically enriched for evolutionarily conserved predicted miR-96, miR-182 or miR-183 target sites.

Modulation of the microRNA cluster miR-183-96-182 expression by the Epstein-Barr virus latent membrane protein 1

Project description:Epstein-Barr virus (EBV) is an oncogenic human herpesvirus involved in the pathogenesis of Burkitt’s lymphoma (BL) and various other lymphoproliferative disorders. In BL, EBV protein expression is restricted to the EBNA-1, but small non-coding RNAs such as the EBERs and micro (mi)RNAs can also be detected. miRNAs play major roles in crucial processes such as proliferation, differentiation and cell death. It has recently become clear that alteration in the expression profile of miRNAs contribute to the pathogenesis of a number of malignancies. During latent infection, EBV expresses 25 viral pre-miRNAs and modulates the expression of specific cellular miRNAs, such as miR-155 and miR-146, which potentially play a role in oncogenesis. Here, we established the small RNA expression profiles of three BL cell lines. Using large-scale sequencing coupled to northern blot and real-time RT-PCR analysis validation, we demonstrated the differential expression of some cellular and viral miRNAs. High-level expression of the miR-183-96-182 cluster and EBV miR-BART cluster was significantly associated with EBV type I latency. This expression was not affected by viral reactivation since TGF-ß1 stimulation did not significantly change the miRNA profiles. However, the expression of latent membrane protein (LMP)-1 triggered down-regulation of the expression of the miR-183-96-182 cluster. We further show that this effect involves the AKT signaling pathway.

The miR-183/96/182 cluster regulates sensory innervation, resident myeloid cells and functions of the cornea through cell type-specific target genes.

Project description:The conserved miR-183/96/182 cluster (miR-183C) is expressed in both corneal resident myeloid cells (CRMCs) and sensory nerves (CSN) and modulates corneal immune/inflammatory responses. To uncover cell type-specific roles of miR-183C in CRMC and CSN and their contributions to corneal physiology, myeloid-specific miR-183C conditional knockout (MS-CKO), and sensory nerve-specific CKO (SNS-CKO) mice were produced and characterized in comparison to the conventional miR-183C KO. Immunofluorescence and confocal microscopy of flatmount corneas, corneal sensitivity, and tear volume assays were performed in young adult naïve mice; 3' RNA sequencing (Seq) and proteomics in the trigeminal ganglion (TG), cornea and CRMCs. Our results showed that, similar to conventional KO mice, the numbers of CRMCs were increased in both MS-CKO and SNS-CKO vs age- and sex-matched WT control littermates, suggesting intrinsic and extrinsic regulations of miR-183C on CRMCs. The number of CRMCs was increased in male vs female MS-CKO mice, suggesting sex-dependent regulation of miR-183C on CRMCs. In the miR-183C KO and SNS-CKO, but not the MS-CKO mice, CSN density was decreased in the epithelial layer of the cornea, but not the stromal layer. Functionally, corneal sensitivity and basal tear volume were reduced in the KO and SNS-CKO, but not the MS-CKO mice. Tear volume in males is consistently higher than female WT mice. Bioinformatic analyses of the transcriptomes revealed a series of cell-type specific target genes of miR-183C in TG sensory neurons and CRMCs. Our data elucidate that miR-183C imposes intrinsic and extrinsic regulation on the establishment and function of CSN and CRMCs by cell-specific target genes. miR-183C modulates corneal sensitivity and tear production through its regulation of corneal sensory innervation.
