Project description:The expression level of miR-608 was found to be down regulated in several types of cancer. In our previous study, a single SNP in miR-608 (rs4919510) was found to be strongly associated with a higher risk of developing sepsis and multiple organ dysfunctions in all 3 independent study cohorts. However, the clinicopathological impact and the exact roles of miR-608 and its underlying molecular mechanisms in inflammation remain to be identified. In order to identify the exact terget gene of miR-608 in monocytes, we constructed lentiviral vectors with has-miR-608 inhibitor sequences and transfected U937 cells.We used microarrays to identified distinct classes of up-regulated genes during this process and look for possible target genes. U937 cells transfected by has-miR-608 inhibitor lentiviral vectors or negative control virus were analyzed. There are three samples in each group.

Project description:There are 19 differentially expressed microRNAs among new HIV-infected cases, old HIV-infected cases and healthy controls. Five microRNAs show trends in healthy controls, new HIV-infected cases and old HIV-infected cases, they are hsa-miR-1291, and hsa-miR-3609 with up-trends, and hsa-miR-3162-3p, hsa-miR-874-5p and hsa-miR-4258 with down-trends.
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.
