Project description:The goal of this experiment was to determine gene expression changes during Sendai virus infection as the result of expression or inhibition of miR-203 in A549 cells. The gene expression profiling experiment was performed with 4 groups (mock infected, Sendai virus infected, Sendai virus infeceted in the presence of exogenous miR-203, and Sendai virus infected in the presence of miR-203 inhibitor) with 3 biological replicates for each group. Total RNA was purified from A549 cells that were mock infected or infected with Sendai virus (Cantell strain, 5pfu/cell) alone or in the presence of miR-203 mimic or inhibitor for 10 hours.

Project description:MicroRNA-203 was up-regulated markedly upon H5N1 virus infection. To identify the potential target genes of miR-203, we constructed a miR-203 knockout A549 cell line. Then wild-type and miR-203 knockout A549 cells were mock-infected or infected with H5N1 virus for 48h. The Agilent Whole Human Genome Oligo Microarray was performed to analyze the mRNA expression profiling. Meanwhile, the online tool TargetScanHuman (http://www.targetscan.org/vert_71/) was used to predict biological targets of miR-203. We combined the predicted genes with the genes differentially expressed in wild-type and miR-203 knockout A549 cells, and preliminarily identified some candidate mRNAs. Then more experiments were performed to further verify these target genes, such as dual-luciferase reporter assay, quantitative real-time PCR or Western blot analysis.
Project description:Small RNAs were profiled during Sendai virus infection of human A549 cells to identify changes in microRNA abundance during the cellular antiviral response. Examination of microRNA abundance during Sendai virus infection.
Project description:We used phosphoproteomics combined with bioinformatics to characterize the global cellular protein phosphorylation events during Sendai virus infection in human lung epithelial cells.
Project description:To investigate the mechanism through which miR-203 inhibited the breast cancer cell invasion, we overpression miR-203 in MDA-MB-231 cell line and performed a microarray to examine the genes which maybe targeted and down-regulated by miR-203.

Project description:Innate immunity is the first line of defense against viral and microbial pathogens. BMDC is critical for innate immunity. To investigate the complicated net signaling after virus invasion, we did a cDNA microarray analysis of BMDC with or without Sendai Virus infection. We used microarrays to find proteins that upregulated by Sendai Virus infection and investigated if these proteins had functions in regulating Sendai Virus induced signaling pathway. BMDC cells are seperated from C57BL6 mice, infected with Sendai Virus or not,cultured and harveseted for RNA extraction and hybridization on Affymetrix microarrays
