Project description:To clarify the gene expression profile in MLE-12 cells transfected with microRNA mimics upon influenza virus infection, we transfected microRNA mimics (mmu-miR-483-3p or Negative control miRNA) into MLE-12 cells and infected A/Puerto Rico/8/1934 (PR8) strain at an MOI of 2 at 24 hours post transfection. RNA was isolated from cells at 12 hours post infection. We found that miR-483-3p transfection down-regulated the genes involved in the innate immunity regulation upon influenza virus infection.
Project description:Purpose: To compare the E9.5 Dgcr8 conditional knockout embryonic heart cells transfected with NC miRNA and miR-541 mimics Methods: In vitro cultured E9.5 Dgcr8 conditional KO heart cells transfected with miR-541-5p and NC miRNA were extracted with TRIZOL 48hrs after transfection, and 10ng total RNA was reverse transcribed and amplified by Smart-seq2 protocol as described (Picelli et al., 2014). Duplicated biological samples were analyzed using Illumina HiSeqX10, Clean reads were mapped to mouse genome (mm9) using BWA software. Results: Genes differentially expressed in E9.5 Dgcr8 cKO embryonic heart cells transfected with NC miRNA and miR-541 were identified. Conclusions: miRNA-541 significantly changes the gene expression profiles of E9.5 Dgcr8 cKO embryonic heart cells and promote the cardiac function
Project description:Studies have shown that miR-361-3p is associated the progression of HCC cells and has potential to be used as a biomarker for cancer therapy. However, the mechanism of how miR-361-3p regulates the progression of HCC cells is not clear. To explore this mechanism, we transfected miR-361-3p mimics into Huh 7 cells , and verified the transfection efficiency with qRT-PCR. Then, we performed transcriptomic analysis using data obtained from RNA-seq of 3 pairs of these transfected cells.
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.
Project description:Nuclear factor κB (NF-κB) pathway plays an important role in hepatocellular carcinoma (HCC) progression. miR-194 was previously shown to reduce the induction of NF-κB activity upon addition of tumor necrosis factor α (TNFα). To clarify the molecular mechanism responsible for the effect of miR-194 on NF-κB pathway, mRNA microarray assays were performed to identify the genes that were suppressed by miR-194. HEK-293T cells transfected with miR-194 mimics were cultured for RNA extraction and hybridization on Affymetrix mRNA microarrays. These were compared against the control, which were HEK-293T cells transfected with negative control mimics.
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.
