Project description:In order to comprehensively identify genes directly regulated by AP4, a genome-wide chromatin-immunoprecipitation analysis (ChIP) followed by next generation sequencing (ChIP-seq) was performed after activation of a conditional AP4 allele in DLD-1 cells. One DLD-1 Sample was sequenced.

Project description:This is a prospective-retrospective study to determine if the expression of the miRNA’s miR-31-3p and miR-31-5p are prognostic of patient outcomes or predictive of the benefit from anti-EGFR therapy in stage III Colon Cancer. The present study will utilize FFPE tumor samples collected from patients enrolled in the PETACC-8 study conducted by the Fédération Francophone de Cancérologie Digestive (FFCD). This phase 3 clinical trial prospectively randomized fully resected stage III colon cancer patients to receive adjuvant treatment with either FOLFOX-4 plus cetuximab or FLOFOX-4 alone.

Project description:The transition of the endothelium to a pro-inflammatory state is key to progression of chronic inflammatory diseases including rheumatoid arthritis, chronic bowel disease and atherosclerosis. In atherosclerosis it is hypothesized that low density lipoproteins (LDL) that become trapped in the intima of the blood vessels are oxidized to minimally modified LDL (mmLDL) and that these serve as an important contributing factors to endothelial dysfunction. Oxidized 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphatidylcholine (OX-PAPC), a model of the active phospholipid components of mmLDL affects the expression of hundreds of genes involved in inflammatory and other biological processes in human aortic endothelial cells (HAECs). We hypothesized that microRNAs (miRNAs) partially regulate this response. Using next generation sequencing, we identified miR-21-3p and miR-27a-5p to be induced 4-fold and 3-fold, respectively in response to OX-PAPC treatment compared to control treatment in HAECs. To identify the targets, we performed whole genome transcript profiling following transient over-expression of these two miRNAs followed by. In total, 1254 genes were down-regulated with 925 of them overlapping between the two miRNAs. Functional enrichment analysis using Gene Ontology predicted that the two miRNAs were involved in the regulation of NF-κB signaling. We characterized the Toll/interleukin-1 receptor (TIR) domain-containing adaptor protein TICAM2 as a direct target of miR-21-3p and miR-27a-5p. Furthermore, we showed that over-expression of miR-21-3p and miR-27a-5p lead to decreased p65 translocation to the nucleus and decreased the expression of known NF-κB downstream target genes confirming both miRNAs’ role in negatively regulating NF-κB signaling in endothelial cells. mRNA expression profiling of human aortic endothelial cells from two separate donors that were transfected with 1 nM microRNA mimics and negative control. The miRIDIAN mimics used were miR-21-3p (Catalog Number:C-301023-01-0005), miR-27a-5p (Catalog No: C-301028-01-0005), negative control (Catalog No: CN-001000-01-05)

Project description:MiRNAs have been shown to alter both protein expression and secretion in different cellular contexts. By combining in vitro, in vivo and in silico techniques, we demonstrated that overexpression of pre-miR-1307 reduced the ability of breast cancer cells to induce endothelial cell sprouting and angiogenesis. However, the molecular mechanism behind this and the effect of the individual mature miRNAs derived from pre-miR-1307 on protein secretion and is largely unknown. Here, we overexpressed miR-1307-3p|0, -3p|1 and 5p|0 in MDA-MB-231 breast cancer cells and assessed the impact of miRNA overexpression on protein secretion by Mass Spectrometry. Unsupervised hierarchical clustering revealed a distinct phenotype induced by overexpression of miR-1307-5p|0 compared to the controls and to the 5’isomiRs derived from the 3p-arm. Together, our results suggest different impacts of miR-1307-3p and miR-1307-5p on protein secretion which is in line with our in vitro observation that miR-1307-5p, but not the isomiRs derived from the 3p-arm reduce endothelial cell sprouting in vitro. Hence these data support the hypothesis that miR-1307-5p is at least partly responsible for impaired vasculature in tumors overexpressing pre-miR-1307.

Project description:To identify putative novel specific targets of mir-199-5p, we overexpressed miR-199a-5p as well as miR-21 and a siRNA targeted against CAV1 in human HFL1 pulmonary fibroblasts (CCL-153) by transfecting them with synthetic pre-miRNAs or a synthetic “negative” pre-miRNA as control (miR-Neg). RNA samples were harvested at 48 hours post-transfection and 2 independent experiments were carried out. Additional samples correspond to HFL1 cells treated or not with 10ng/ml TGFbeta for 48 hours in the absence of serum (2 independent experiments). 2 independent experiments performed in a one color design, corresponding to 7 conditions (miR-Neg, miR-199-5p, miR-21, si-Neg, si-CAV1, control, TGFbeta) and a total of 14 samples.
