The goal of this study was to identify ion channels, specifically transient receptor potential cation channel A (trpA1) channels, that were highly expressed and enriched in nociceptive sensory neurons of Drosophila larvae. In class IV da sensory neurons, we find that TrpA1 is the most highly expressed trpA1 channel of the 14 trpA1 channels in Drosophila, and that its expression is highly enriched when compared to the whole animal transcriptome. Overall design: Four biological replicates of 100 Drosophila melanogaster larval class IV dendritic arborization sensory neurons and five biological replicates of whole Drosophila melanogaster larvae were profiled by mRNA-Seq
TrpA1 activation in peripheral sensory neurons underlies the ionic basis of pain hypersensitivity in response to vinca alkaloids.

View SamplesAnopheles gambiae mosquitoes play an important role in malaria transmission. In sub-Saharan Africa, the dry season can last several months. The mechanisms for mosquito population to survive through the dry season are poorly understood. One possible mechanism is that adults increase their desiccation tolerance over the dry season. Genetic analyses have shown that inversions 2La, 2Rb, 2Rc, 2Rd and 2Ru are associated with aridity resistance, however little is known about the transcriptional response of genes in response to desiccation.

View SamplesPax6 is a transcription factor with key functional roles in embryonic development. In order to identify downstream effectors of Pax6 in the developing cerebral cortex we performed microarray analysis. We compared gene expression profiles of cortical tissues isolated from wild type and Pax6-/- mouse embryos.
Cellular retinaldehyde-binding protein (CRALBP) is a direct downstream target of transcription factor Pax6.

View SamplesThe development of the central nervous system (CNS) is a complex process that must be exquisitely controlled at multiple levels to ensure the production of appropriate types and quantity of neurons. RNA alternative polyadenylation (APA) contributes to transcriptome diversity and gene regulation and has recently been shown to be widespread in the CNS. However, previous studies have been primarily focused on the tissue specificity of APA and developmental APA change of whole model organisms, a systematic survey of APA usage is lacking during CNS development. Here we conducted global analysis of APA during mouse retinal development, and identified stage-specific polyadenylation (pA) sites that are enriched for genes critical for retinal development and visual perception. Moreover, we demonstrated 3'UTR lengthening and increased usage of intronic pA sites over development that would result in gaining many different RBP (RNA binding protein) and miRNA target sites. Furthermore, we showed that a considerable number of polyadenylated lncRNAs are co-expressed with protein-coding genes involved in retinal development and functions. Together, our data indicate that APA is highly and dynamically regulated during retinal development and maturation, suggesting that APA may serve as a crucial mechanism of gene regulation underlying the delicate process of CNS development. Overall design: PA-seq of mouse retina tissues at embryonic day E13.5, E15.5, E18.5 and postnatal day P0, P6, P21

View SamplesIL-17-producing CD8+ (Tc17)T cells are implicated in the pathogenesis of multiple sclerosis (MS), thereby representing a promising target for therapy. We found that dimethyl fumarate (DMF), a first-line medication for MS upregulated reactive oxygen species (ROS) by glutathione depletion in murine Tc17 cells, which limited IL-17 and diverted Tc17 cells towards cytotoxic T lymphocyte (CTL) signature. DMF enhanced PI3K-AKT-FOXO1-T-bet- as well as STAT5-signaling leading to restricted permissive histone state at the Il17 locus. T-bet-deficiency, inhibiting PI3K-AKT, STAT5 or histone deacetylases prevented DMF-ROS-mediated IL-17 suppression. In MS patients with stable response, DMF suppressed IL-17 production by CD8+ T-cells and triggered diversion from Tc17 towards CTL signature along with enriched ROS-, PI3K-AKT-FOXO1-signaling, demonstrating comparable regulation across species. Accordingly, in the mouse model for MS, DMF limited Tc17-encephalitogenicity. Our findings disclose DMF-ROS-AKT-driven pathway, which selectively modulates Tc17 fate to ameliorate MS, thus opening avenue to develop markers and targets for specific therapy. Overall design: Examination of DMF-induced expression changes in 3 conditions, 3 samples each: murine TC17 cells without treatment as control group, murine Tc17 cells treated with DMF and murine Tc17 cells treated with DMF and Glutathione(GSH)
