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:MicroRNAs (miRNAs), small non-coding RNAs, are powerful and extremely versatile regulators of the gene expression in cells, playing an important role in every step of cancer progression. Here, we report a list of transcripts regulated by miR-662 and miR-24-2-5p transient overexpressions using miRNA MIMIC transfection (MIMIC-miR-662 and MIMIC-miR-24-2-5p, respectively) compared to control (MIMIC-negCTRL-FAM+) at 36 hours post-transfection in human MDA-MB-231-luc2-NW1 (NW1) (for miR-662 and miR-24-2-5p) and MCF7 (only for miR-24-2-5p) breast cancer cell lines. We found 38 transcripts significantly deregulated (17 downregulated, 21 upregulated) in miR-662-overexpressing NW1 cells compared to mock-transfected cells; 222 (187 downregulated, 35 upregulated) and 34 (32 downregulated, 2 upregulated) transcripts deregulated in miR-24-2-5p-overexpressing NW1 and MCF7 cells, respectively, compared to mock-transfected cells. Furthermore, a total of 30 transcripts (29 downregulated, 1 upregulated) were shared between miR-24-2-5p-overexpressing NW1 and MCF7 cells compared to mock-transfected cells. For miR-662, which we found to promote breast cancer metastasis by stimulating cancer cell stemness (Puppo et al., 2023), we observed the deregulation of Cell Migration Inducing Hyaluronidase 1 (CEMIP), Interleukin 6 receptor (IL6R), High Mobility Group AT-Hook 2 (HMGA2), Small Ubiquitin Like Modifier 3 (SUMO3), and Polymerase (DNA) Delta Interacting Protein 2 (POLDIP2), which reinforced the evidence of the involvement of miR-662 in the acquisition of a stem-like phenotype by human NW1 breast cancer cells and miR-662 contribution to breast cancer bone metastasis formation. For miR-24-2-5p, we found that the downregulation of two transcripts, WD Repeat and FYVE Domain Containing 1(WDFY1) and SH3 Domain Binding Glutamate Rich Protein Like 2 (SH3BGRL2), might explain a possible role of miR-24-2-5p as a tumour suppressor by reducing breast cancer cell invasive properties.
