Description
Here we characterize the changes in the forebrain transcriptome resulting from the deletion of the transcription factor Lhx6, generated by RNA-seq technology with biologic replication. Lhx6 is an essential regulatory gene in the development of cortical interneurons generated in the medial ganglionic eminences of the embryonic brain. This data contains insights into gene networks important for the development of medial ganglionic eminence derived interneurons. Overall design: Forebrain total RNA profiles of 15-day old Lhx6 heterozygote (Het) and Lhx6 null mice were generated by deep sequencing, using Illumina GAIIx. Mutant allele used was Lhx6tm2Vpa (MGI:3702518). Each individual sample was comprised of two animals. Four samples for Lhx6 Het and three samples for Lhx6 null mice were generated and analysed in parallel.

Description
Regeneration requires cells to regulate proliferation and patterning according to their spatial position. Positional memory is a property that enables regenerating cells to recall spatial information from the uninjured tissue. Positional memory is hypothesized to rely on gradients of molecules, few of which have been identified. Here, we quantified the global abundance of transcripts, proteins and metabolites along the proximodistal axis of caudal fins of uninjured and regenerating adult zebrafish. Using this approach, we uncovered complex overlapping expression patterns for hundreds of molecules involved in diverse cellular functions, including developmental and bioelectric signaling as well as amino acid and lipid metabolism. Moreover, 32 genes differentially expressed at the RNA level had concomitant differential expression of the encoded proteins. Thus, the identification of proximodistal differences in levels of RNAs, proteins, and metabolites will facilitate future functional studies of positional memory during appendage regeneration. Overall design: RNA-seq was performed on 5 biological replicates for each of 3 positions along the proximodistal axis of the caudal fin; proximal, middle and distal (15 total samples). Each biological replicate was a pool of fin regions cut from 2 male and 2 female zebrafish.

Description
Spinal muscular atrophy (SMA) is a neurodegenerative disease which exhibits selective motor neuron death caused by a ubiquitous deficiency of the survival motor neuron (SMN) protein. It remains unclear how the ubiquitous reduction of SMN lead to death in selective motor neuron pools. Medial motor neuron columns (MMC) are vulnerable, whereas lateral motor columns (LMC) are resistant to motor neuron death in SMA. Here we performed microarray and pathway analysis comparing cholera toxin subunit B (CTb) labeled vulnerable MMC and resistant LMC of pre-symptomatic SMA with corresponding motor neuron columns of control mice to identify pathways involved in selective motor neuron death in SMA. WT is FVB. SMN is Delta7 (SMN7;SMN2;Smn-) on a FVB background.

Description
Translational profiling methodologies enable the systematic characterization of cell types in complex tissues such as the mammalian brain, where neuronal isolation is exceptionally difficult. Here, we report a versatile strategy to profile CNS cell types in a spatiotemporally-restricted fashion by engineering a Cre-dependent adeno-associated virus expressing an EGFP-tagged ribosomal protein (AAV-FLEX-EGFPL10a) to access translating mRNAs by TRAP. We demonstrate the utility of this AAV to target a variety of genetically and anatomically defined neural populations expressing Cre recombinase and illustrate the ability of this viral TRAP (vTRAP) approach to recapitulate the molecular profiles obtained by bacTRAP in corticothalamic neurons across multiple serotypes. Furthermore, spatially restricting AAV injections enabled the elucidation of regional differences in gene expression within this cell type. Taken together, these results establish the broad applicability of the vTRAP strategy for the molecular dissection of any CNS or peripheral cell type that can be engineered to express Cre. Overall design: Polysome-bound mRNAs from TRAP IPs were compared to whole tissue mRNAs. Data was collected from MCH neurons in hypothalamus using vTRAP, cortical layer 6 Ntsr1 neurons using vTRAP, and cortical layer 6 Ntsr1 neurons using bacTRAP. We include vTRAP data from three AAV serotypes for the cortical Ntsr1 cells. We collected three replicates for IP and inputs for vTRAP experiments, while bacTRAP data was collected in duplicate.

Stroke is a multiphasic progress characterized by neuron damage due to hypoxia followed by secondary damage from the subsequent inflammatory immune response. Infiltrating myeloid cells induce cerebral damage through pro-inflammatory cytokines, chemokines, proteases and generation of reactive oxygen species (ROS).

Description
About 40% IBD patients treated with anti-TNF antibodies do not respond to therapy. Baseline biomarkers of response are therefore of interest. By combining computational deconvolution of gene expression and meta-analysis approaches we identified cellular biomarkers in tissue (validated in 2 cohorts by IHC of biopsies), and investigated associated gene biomarkers in blood. This dataset provides data from the validation cohort III (blood).
