Project description:In Caenorhabditis elegans, VA and VB motor neurons arise as lineal sisters but synapse with different interneurons to regulate locomotion. VA-specific inputs are defined by the UNC-4 homeoprotein and its transcriptional corepressor, UNC-37/Groucho, which function in the VAs to block the creation of chemical synapses and gap junctions with interneurons normally reserved for VBs. To reveal downstream genes that control this choice, we have employed a cell-specific microarray strategy that has now identified unc-4-regulated transcripts. One of these genes, ceh-12, a member of the HB9 family of homeoproteins, is normally restricted to VBs. We show that expression of CEH-12/HB9 in VA motor neurons in unc-4 mutants imposes VB-type inputs. Thus, this work reveals a developmental switch in which motor neuron input is defined by differential expression of transcription factors that select alternative presynaptic partners. The conservation of UNC-4, HB9, and Groucho expression in the vertebrate motor circuit argues that similar mechanisms may regulate synaptic specificity in the spinal cord.

The conservation of UNC-4, HB9, and Groucho expression in the vertebrate motor circuit argues that similar mechanisms may regulate synaptic specificity in the spinal cord. We employ the mRNA-tagging method to isolate poly(A) RNA from wildtype and unc-37 mutant A-class motor neurons by expressing a 3X FLAG-tagged poly(A) binding protein PAB-1 in DA/VA neurons under control of the unc-4 promoter. A 2-round IVT protocol (modified from the Affymetrix small-sample protocol) was used to convert starting RNA into biotinylated aRNA.

Project description:Purpose: To uncover immune and longevity genes and pathways that are modulated by the homeodomain PITX1/UNC-30, which plays a vital role in the GABAergic signaling in C elegans Methods: RNA was extracted from synchronized L4 stage unc-30(ok613) and WT animals grown at 20 C using Qiagen extraction kits and following standard methods Results: RNA seq analyses shows enriched and signficant upregulated immune, neuropeptide, ageing and metabolism genes and pathways that are dependent of GABAergic signaling Conclusions: Our study uncovered GABAgergic signaling to be modulator of the innate immunity in C elegans

Project description:Purpose: To uncover immune mediated genes and pathways by Pseudomonas aeruginosa infection that are modulated by the homeodomain PITX1/UNC-30, which plays a vital role in the GABAergic signaling in C. elegans Methods: RNA was extracted from synchronized Pseudomonas aeruginosa infected L4 stage unc-30(ok613) and WT using Qiagen extraction kits and following standard methods. The animals were grown on OP50 at 20 C and infected at 25 C. Results: RNA seq analyses shows enriched and signficant Pseudomonas aeruginosa mediated upregulated immune, neuropeptide and metabolism genes and pathways that are dependent of GABAergic signaling Conclusions: Our study uncovered GABAgergic signaling to be modulator of the innate immunity in C elegans during Pseudomonas aeruginosa infection

Project description:modENCODE_submission_3254 This submission comes from a modENCODE project of Michael Snyder. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: We are identifying the DNA binding sites for 300 transcription factors in C. elegans. Each transcription factor gene is tagged with the same GFP fusion protein, permitting validation of the gene's correct spatio-temporal expression pattern in transgenic animals. Chromatin immunoprecipitation on each strain is peformed using an anti-GFP antibody, and any bound DNA is deep-sequenced using Solexa GA2 technology. For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf EXPERIMENT TYPE: CHIP-seq.

Project description:To gain molecular insights on how UNC-49 regulates C. elegans innate immunity, we used RNA sequencing to profile gene expression in unc-49(e407) animals relative to wild-type animals with or without P. aeruginosa(PA14) infection. We found that UNC-49 suppresses the expression of insulin pathway genes, and lack of UNC-49-mediated suppression in unc-49(e407) animals contributes to their improved survival against P. aeruginosa infection.
