Transcriptomics analysis of cells transfected with miR-183 cluster mimics and immunostimulated with poly(I:C)

Project description:Our work demonstrated that miR-183 cluster regulates IFN production and signaling We used microarrays to detail the effect of miR-183 cluster on hepatic gene expression during immunostimulation with poly(I:C). Our finding suggests enrichment of pathways involved in IFN production and signaling. Amoung the miR-183 repressed genes, we identifies PPP2CA and TRIM27, which are negative regulators of the innate immune response.

miR-182 and miR-183 act as GDNF mimics in midbrain neurons

Project description:We found in primary midbrain neurons the expression of miR-182 and miR-183 is increased with the treatment of GDNF. Further we showed that the transfaction with these two miRNA mimics resulted into the increased neurite length and regeneration in vitro. These mimics also showed neuroprotection of dopamenergic neurons in vitro and in vivo with an effect similar to GDNF. Finally we showed this effect is mediated by the downregulation of Foxo transcription factors.

Negative control and mir-342-3p mimics-transfected RAW264.7 mouse macrophages.

Project description:RAW264.7 mouse macrophages were transfected with negative control and miR-342-3p mimics and subjected to microarray analysis 18 hours after the transfection. We used microarray to obtain global mRNA expression data of negative control and miR-342-3p mimics-transfected RAW264.7 cells.

Small RNA and High Molecular Weight RNA Deep Sequencing Analysis of miR-17~92 Mimics Transfected HeLa cells

Project description:Transient transfection of miRNA mimics are widely used to alter microRNA expression in cells. The goal of this study is to perform small RNA deep sequencing analysis of HeLa cells transfected with miR-17~92 cluster and address potential source of non-specific effects caused by this approach. HeLa cells were cultured as adherent cells. Equal molar concentration of miRNA mimics of miR-17~92 (100nM, 16.7nM each) were transfected and harvedsted at 6h post-transfection for small RNA deep sequencing analysis.

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.

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.
