Project description:We used microarrays to detail the global programme of gene expression that occurs in response to miR-449 or miR-34 overexpression in proliferating HAECs. Each donors were transfected with pre-miR-Negative control, pre-miR-449a and pre-miR-449b. The donors 3 and 4 were morever transfected with pre-miRs-34 (34a, 34b-5p, 34c-5p).
Project description:Here we performed a RNA-seq experiment on samples of adherent cultures of mouse neural stem cells (NS5 cell line) under normal growth conditions and after 4 hours of treatment with the gamma-secretase inhibitor LY 411575. This resulted in the generation of a genome-wide mRNA expression pattern and quantification for these cells in the two conditions.
Project description:We have performed a systems-level analysis of the RFX/Daf-19 family transcription factor, Rfx2. Using a combination of high-throughput sequencing of Rfx2-regulated transcripts and chromosomal binding sites, we provide a comprehensive accounting of the target genes by which Rfx2 controls ciliogenesis and cilia beating in vertebrates. RNA-seq: two biological replicates for control and RFX2 knockdown by morpholino injection, ChIP-seq: RFX2-GFP pulldown with GFP antibody, GFP only expression used as control
Project description:The generation of diverse neuronal types and subtypes from multipotent progenitors during development is crucial for assembling functional neural circuits in the adult central nervous system. It is well known that Notch signalling pathway through the inhibition of proneural genes is a key regulator of neurogenesis in the vertebrate central nervous system. However, its role during hypothalamus formation along with its downstream effectors remains poorly defined. Here, we have transiently blocked Notch activity in chick embryos and used global gene expression analysis to provide evidence that Notch signalling modulates the generation of neurons in the early developing hypothalamus by lateral inhibition. Most importantly, we have taken advantage of this model to identify novel targets of Notch signalling, such as Tagln3 and Chga, which were expressed in hypothalamic neuronal nuclei. This data gives essential advances into the early generation of neurons in the hypothalamus. We demonstrate that inhibition of Notch signalling during early development of the hypothalamus enhances expression of several new markers. These genes must be considered as important new targets of the Notch/proneural network. Four sets of samples were used for analysing transcriptome changes in DAPT treated chicl embryos. The rostral part of the head (including the anterior forebrain, optic vesicles and overlying tissue) was collected from control embryos and DAPT-treated embryos at stage HH13.
