Project description:To investigate the effect of miR-203 in type 2 diabetes, target genes of miR-203 need to be investigated. The β cell specific miR-203 transgene (miR-203 TG) mice was constructed, and scRNA-seq was then performed on mouse islets.

Project description:We identify numerous miR-203 in vivo targets that are highly enriched for the promotion of cell cycle and cell division. Importantly, individual targets including p63, Skp2 and Msi2 play distinct roles downstream of miR-203 to regulate the cell cycle and long-term proliferation. Together, our findings reveal rapid and widespread impact of miR-203 on the self-renewal program during the epidermal differentiation and provide mechanistic insights for the potent role of miR-203 where coordinated repression of multiple targets is required for the function of this miRNA. We used microarrays to measure transcriptome changes upon miR-203's induction in mouse skin and identified new targets of miR-203.

We used microarrays to measure transcriptome changes upon miR-203's induction in mouse skin and identified new targets of miR-203. We use two pairs of biological duplicates to perform the microarray analysis from the epidermal samples harvested from K14-rtTA/TRE-miR-203/K14-H2BGFP (DP) and TRE-miR-203/K14-H2BGFP (SP) littermates at P4, 24h after the Dox injection.
Project description:Expression profiling of prostate EPT1 cells transducted with two types of miRNAs (miR-182, miR-203) and RNAi clones knocking down SNAI2.
Project description:The goal of this experiment was to determine gene expression changes during IFNα treatment 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, IFNα treated, IFNα treated in the presence of exogenous miR-203, and IFNα treated in the presence of miR-203 inhibitor) with 3 biological replicates for each group. Total RNA was purified from A549 cells that were untreated of treated with IFNα (1000 units/mL) alone or in the presence of miR-203 mimic or inhibitor for 10 hours.
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: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.
