Description
Small molecule splicing modifiers have been extensively described which target the generic splicing machinery and thus have low target specificity. We have identified potent splicing modifiers with unprecedented high selectively, correcting the splicing deficit of the SMN2 (survival motor neuron 2) gene in Spinal Muscular Atrophy (SMA). Here we show that they directly bind to two sites of the SMN2 pre-mRNA, thereby stabilizing a novel ribonucleoprotein (RNP) complex in the SMN2 gene that is critical for the high target specificity of these small molecules over other genes. In addition to the therapeutic potential of these molecules for treatment of SMA, our work may have wide-ranging consequences for further research to identify small molecules that target splicing correction of specific genes by interacting with tertiary RNA structures. Overall design: mRNA profiling of type I SMA fibroblasts treated with NVS-SM1

Description
Small RNAs (sRNA) that act by base pairing with trans-encoded mRNAs modulate metabolism in response to a variety of environmental stimuli. Here, we describe an Hfq-binding sRNA (FnrS) whose expression is induced upon a shift from aerobic to anaerobic conditions and which acts to down regulate the levels of a variety of mRNAs encoding metabolic enzymes. Anaerobic induction in minimal medium depends strongly on FNR but is also affected by ArcA and CRP. Whole genome expression analysis showed that the levels of at least 32 mRNAs are down regulated upon FnrS overexpression, 15 of which are predicted to base pair with FnrS by TargetRNA. The sRNA is highly conserved across its entire length in numerous enterobacteria, and mutation analysis revealed that two separate regions of FnrS base pair with different sets of target mRNAs. The majority of the target genes previously reported to be down regulated in an FNR-dependent manner lack recognizable FNR binding sites. We thus suggest that FnrS extends the FNR regulon and increases the efficiency of anaerobic metabolism by repressing the synthesis of enzymes that are not needed under these conditions.

Description
To better understand the scale of gene expression changes that occur during the formation of mature adipocytes from preadipocytes, we compared and characterised the transcriptome profile of mesenchymal stromal cells derived from human adipose tissue, otherwise known as adipose-derived stromal cells (ASCs), undergoing adipocyte differentiation on day 1, 7, 14 and 21 (representing the early to late stage process of adipogenesis). Microarray technique was systematically employed to study gene expression in adipose-derived stromal cells during adipogenic differentiation over a 21 day period to identify genes that are important in driving adipogenesis in humans.

Description
Dendritic cells are the initiators of the adaptive immune response, therefore its gene expression allow us to predict the responses to vaccination. We used bone marrow derived dendritic cells (BMDC) to analyze the gene expression that result from the exposure to adjuvants. We use model antigen OVA and cyclic di-AMP (CDA) as an adjuvant in order to characterize the genes involved in the activation of dendritic cells by CDA alone or when the antigen is present.

Description
We report the RNAseq analysis of human dermal fibroblasts which have been treated by protocols to stimulate their differentiation towards the otic lineage. This was achieved by transfection with different transcription factors with the aim to induce an initial reprogramming of the cells and was followed by growth factor treatments known to promote otic differentiation. The results show that a partial differentiation towards the otic lineage is achieved by these protocols. Overall design: RNAseq profiles were obtained from human dermal fibroblasts with two different protocols. Prior to treatment with growth factors stimulating differentiation, the samples were either transfected with the transcription factors OCT4 or a combination of ATOH1, POU4F3 and GFI1.

Description
The zebrafish is a powerful model for the study of hematopoietic stem and progenitor cells (HSPC). We have developed a novel HSPC-specific transgenic line (Runx1+23:GFP). We have used this line in time-lapse live imaging studies to track the migration of HSPC during development. We have also performed a chemical genetic screen to find small molecules that modulate HSPC numbers during development. Treating embryos from 2-3 days post fertilization (2-3 dpf) then fixing for in situ staining with HSPC probes cmyb and runx1, we found the compound lycorine increased HSPC numbers. Applying this compound during time-lapse live imaging showed increased accumulation of Runx+ HSPC in the caudal hematopoietic tissue (CHT). Treatment from 2-3 dpf, then washing off the compound, had a sustained effect on the size of the HSPC with Runx+ numbers higher at 5 and 7 dpf.

Description
Continuous contact with self-major histocompatibility complex ligands is essential for the survival of naive CD4 T cells. We have previously shown that the resulting tonic TCR signaling also influences their fate upon activation by increasing their ability to differentiate into induced regulatory T cells. To decipher the molecular mechanisms governing this process, microarray data comparing highly (Ly-6C-) and lowly (Ly-6C+) Self-reactive naive CD4 T cells were obtained.
