Description
RNAseq analysis was conducted to complement the targeted and untargeted metabolomics analysis of livers overexpressing the CoA-degrading enzyme Nudt7 or GFP (control). Lipid metabolism requires coenzyme A (CoA), which is found in multiple subcellular compartments including the peroxisomes. In the liver, CoA levels are dynamically adjusted between the fed and fasted states. The elevation in CoA levels that occurs during fasting is driven by increased synthesis but also correlates with decreased expression of Nudt7, the major CoA-degrading enzyme in the liver. Nudt7 resides in the peroxisomes and we overexpressed this enzyme in mouse livers to determine its effect on the size and composition of the hepatic CoA pool in the fed and fasted states. Nudt7 overexpression did not change total CoA levels but decreased the concentration of short-chain acyl-CoAs and choloyl-CoA in fasted livers, when endogenous Nudt7 activity was lowest. The effect on these acyl-CoAs correlated with a significant decrease in the hepatic bile acid content and in the rate of peroxisomal fatty acid oxidation, as estimated by targeted and untargeted metabolomics, combined with the measurement of fatty acid oxidation in intact hepatocytes. Identification of the CoA species and metabolic pathways affected the overexpression on Nudt7 in vivo supports the conclusion that the nutritionally-driven modulation of Nudt7 activity could contribute to the regulation of the peroxisomal CoA pool and peroxisomal lipid metabolism. Overall design: Liver mRNA profiles of 4 mice injected with adeno-associated virus to overexpress Nudt7 and 4 mice injected with adeno-associated virus to overexpress GFP (control) were generated by RNAseq using Illumina HiSeq1500

Description
Medulloblastoma is the most common pediatric CNS cancer. In order to identify important molecules important for deregulated tumor cell growth, we use microarray to detail the global gene expression profile in Shh-driven mouse medulloblastomas and determine the most differentially expressed genes compared to the control wild-type cerebellum.

Description
Asthma is a chronic inflammatory respiratory disease affecting over 300 million people around the world. Some asthma patients remain poorly controlled by conventional therapies and experience more life-threatening exacerbations. While patients with severe, refractory disease represent a heterogeneous group, a feature shared by most includes glucocorticoid insensitivity. We sought to characterize differences in the airway smooth muscle transcriptome response to glucocorticoids in fatal asthma vs. non-asthma donors. RNA-Seq was used to measure airway smooth muscle transcript expression differences between 9 donors with fatal asthma and 8 non-asthma donors. Cells from each donor were treated with budesonide or with vehicle control. Poly(A)-selected RNA-Seq libraries were prepared with the Illumina TruSeq method. An Illumina HiSeq 2500 instrument was used to generate 125 base pair paired-end reads. Overall design: Transcriptome profiles obtained via RNA-Seq for airway smooth muscle cells from 9 fatal asthma and 8 non-asthma donors treated with budesonide (100nM for 24h) or vehicle control were compared

Description
Induction of dnFGFR2bfor 3 partially overlapping intervals at the early stages of otocyst morphogenesis revealed expected and novel up and downregulated genes that were validated by in situ hybridization analysis. Cell cyle genes were enriched in the downregulated datasets and human hearingloss genes were enriched in the upregulated datasets. Overall design: Differential mRNA expression analysis of pooled Rosa26rtTA/+ (control) and pooled Rosa26rtTA/+;Tg(tetO-s(dn)Fgfr2b)/+ (experimental) embryos induced with doxycycline for the indicated intervals. N=4 biological replicates per treatment (i.e. 4 pregnant females)

Description
A protocol was established for the derivation of Schwann cell-like cells from human BMSCs. The commitment to the Schwann cell fate was acquired by Schwann cell-like cells in co-culture with rat DRG neurons. Microarray analysis provided evidence that the human BMSC-derived Schwann cells were functionally mature.

Description
The goal of this study was to investigate the role of intragenic CTCF in alternative pre-mRNA splicing through a combined CTCF-ChIP-seq and RNA-seq approach. CTCF depletion led to decreased inclusion of weak upstream exons. Overall design: CTCF ChIP-seq was performed in BJAB and BL41 B cell lines and normalized relative to Rabbit Ig control IP-seq reads. RNA-seq was performed in BJAB and BL41 cells transduced with shRNA against CTCF or RFP as a control, and in untransduced cells as well.
