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.

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.

The miR-183/96/182 cluster is a checkpoint for resident immune cells and shapes the cellular landscape of the cornea.

Project description:The conserved miR-183/96/182 cluster (miR-183C) regulates both corneal sensory innervation and corneal resident immune cells (CRICs). This study is to uncover its role in CRICs and in shaping the corneal cellular landscape at a single-cell (sc) level.

Expression data from the RWPE-1 prostate epithelial cell line overexpressing the miR-183 family cluster

Project description:The full genomic miR-183 cluster (4.8kb) was cloned into lentiviral vector CD511B-1 with polycistronic GFP. RWPE-1 were transduced with a lentivirus from this vector (RWPE-1 183FC), or a CD511B-1 scrambled control with polycistronic GFP (RWPE-1 control). RWPE-1 were FACS sorted by GFP expression and expanded in culture. In RWPE-1 183FC, the miR-183 family members, miR-182, miR-96, and miR-183 were confirmed to be over-expressed at physioloically relevent levels, similar to the increased expression observed in prostate cancer epithelium.

Transcriptional profiling of lung cancer cells transfected with Zeb1.

Project description:To elucidate the mechanisms by which the mir-200 and the miR-183~96~182 cluster could regulate EMT and thus cellular migration, invasion and metastasis in NSCLC, we searched for common predicted targets of these microRNA families that might have a potential role in these biological processes. First we performed a cross comparison of multiple gene expression datasets from our mouse models of metastasis. We overlapped 224 genes that were elevated greater than four-folds upon Zeb1 induction in 393P cells with 210 genes that showed greater than two-fold increase in expression in the metastatic 344SQ cells compared to the non-metastatic 393P cells and 143 genes that were repressed to less than 0.5-fold in cells with exogenous expression of miR-200. This resulted in an enriched list of 45 genes that are potential miR-200 targets having a role in the process of EMT and metastasis. Next we performed an overlap of genes that were predicted targets of the miR-200 family members and the miR-183~96~182 cluster using the microRNA prediction algorithms miRanda (www.microRNA.org) and identified a list of 17 highly conserved common targets with a mirSVR score less than -6.0. The only 2 genes common in both the overlapping subsets were Zeb1 and Foxf2.

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.

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.

sRNA sequencing of liver from lean rats and ZDF rats treated with vehicle or colesevelam

Project description:Colesevelam is a bile acid sequestrant approved to treat both hyperlipidemia and type 2 diabetes, but the mechanism for its glucose lowering effects is not fully understood. The aim of this study was to investigate the role of hepatic microRNA’s as regulators of metabolic disease and to investigate the link between the cholesterol and glucose lowering effects of colesevelam. To quantify the impact of colesevelam treatment in rodent models of diabetes, metabolic studies were performed in Zucker Diabetic Fatty (ZDF) rats and db/db mice. Colesevelam treatments significantly decreased plasma glucose levels and increased glycolysis in the absence of changes to insulin levels in ZDF rats and db/db mice. High-throughput sequencing and real-time PCR were used to quantify hepatic miRNA and mRNA changes, and the cholesterol-sensitive miR-96/182/183 cluster was found to be significantly increased in livers from ZDF rats treated with colesevelam compared to vehicle controls. In summary, these results support that colesevelam likely improves glycemic control through hepatic miR-96/182/183, a mechanism that directly links cholesterol and glucose metabolism.
