Project description:Investigation of whole genome gene expression level changes in miR-139-5p mimic-treated EC109 cells, compared to the scrambled negative controls. A four chip study using total RNA recovered from two separate cultures of miR-139-5p mimic-transfected EC109 cells and two separate cultures of scrambled negative control-transfected EC109 cells. Each chip measures the expression level of 44,049 genes from human esophageal cancer cell EC109 with three 60-mer probe pairs per gene.

Project description:Whole transcriptome Identification of direct targets of miR-139-5p using biotinylated pull-downs found that this miRNA has roles in breast cancer invasion and migration. MCF7 cells were transfected with biotinylated miR-139-5p. The miRNAs and target mRNA were pulled down with streptavidin and compared to the input control.
Project description:To evaluate gene expression alteration following miR-139-5p transfection in glioma cells. We find a significant downregulation of two transcriptional factors, E2F3 and HoxA9. Total RNA were extracted from U87, LN229 and U251 glioma cells transfected with miR-139-5p or miRNA negative control.
Project description:miR-125b-5p is a well known miRNA already describded in several forms of cancer. miR-125b-5p is expressed in adipose tissue, adipocytes as well as their precursor cells. We aim to invest the role of miR-125b-5p in white adipocytes conversion into brite adipocytes. To get an idea about putative targets of miR-125b-5p in adipocyte conversion, we transfected miR-125b-5p mimic in human Multipotent Adipose-Derived Stem (hMADS) cells, differenciated in white adipocytes. Gene expression profiling is performed 48h after hMADSC transfection. Two-condition experiment, hMADS cells at day 16 after conversion of white adipocytes into brite adipocytes, comparison of cells transfected with a mimic miR-125b-5p to cells transfected with a negative controle. Biological replicates: 4, indepently grown and harvested. On each array, one biological replicate of mimic miR-125b-5p transfected cells was directly compared to one biological replicate of mimic negative control transfected cells (serving as reference sample). All hybridizations were repeated with reversed dye assignment (dye-swap) as technical replicates.
Project description:Transcriptional profiling of human papillary thyroid cancer cells comparing control untreated BCPAP cells with BCPAP cells transfected with miR-145b-5p mimic. Two-condition experiment, BCPAP cells vs. miR-146b-5p transfexted BCPAP cells. Biological replicates: 1 control sample, 1 transfected sample.

Project description:We studied the impact of hsa-miR-139-5p on the protein output by means of an iTRAQ-based approach. First, we established two CAL-62 isogenic cell lines expressing either the mature hsa-miR-139-5p or a non-targeting control upon a doxycycline inducible promoter (PTRE3G-tGFP, Dharmacon). Total proteins of P-tGFP-hsa-miR139-5p untreated or treated with doxycycline (1ug/ml) for 96 and 120 hours were isolated and labeled with iTRAQ® reagent 8-plex. Two independent experiments were performed.
