Project description:Our work seeks to understand the role of neuropeptide signaling in the regulation of metabolism and cellular stress. The primary goal of this sequencing experiment was to determine how whole animal expression of FLP-17 changes in the context of different extrachromasomal arrays and how this corresponds to hsp-4p::gfp reporter expression. As a secondary goal, we sought to determine how increasing FLP-17 expression modulates downstream transcriptional pathways.

Project description:Temperature is a prominent environmental stimulus that influences life span. Previous studies indicate that in Caenorhabditis elegans, thermosensory perception in the AFD neuron maintains life span at warm temperatures. How thermosensation is translated into neuronal signals that shape aging remains elusive. We found that the Caenorhabditis elegans CREB crh-1, as well as several key genes in AFD thermosensory transduction, were specifically required for normal life span at warm temperatures. crh-1 acted in the AFD to increase transcription of the CRE-containing neuropeptide gene flp-6 in a temperature-dependent manner. Both crh-1 and flp-6 were necessary and sufficient for longevity at warm temperatures, and their effects depended on the AIY interneuron. Moreover, flp-6 signaling downregulated ins-7/insulin and several insulin pathway genes, whose activity compromised life span. We postulate that temperature experience is integrated in the thermosensory neurons to generate CREB-dependent neuropeptide signals that antagonize insulin signaling and promote temperature-specific longevity.

Project description:To identify genes whose expression in Caenorhabditis elegans is regulated by unc-43/CamKII or egl-8/PLCbeta during adulthood, we performed an exploratory whole transcriptome RNA-sequencing (RNA-seq) study on unc-43(gf), unc-43(-), egl-8(-) and corresponding unc-43(+)/egl-8(+) control worms. To further account for potential influences of genetic background on unc-43/egl-8 function, these experiments were conducted in long-lived insulin-receptor defective [daf-2(-)], as well as in otherwise wildtype [i.e daf-2(+)] strains.

Project description:Depending on the cellular context, TF expression can vary dramatically both spatially and temporally. These differences in expression patterns can result in tissue-specific differences in TF binding to downstream targets. To identify targets on a tissue-specific basis, Targeted DamID (TaDa) has been recently introduced to generate TF binding profiles in various models including C. elegans. However, TaDa suffers from portability such that a new promoter-TF fusion transgene must be constructed for every new experimental condition of interest. Here, we adapt NanoDam for usage in C. elegans, which relies on the use of endogenous TF-GFP knock-ins, a plethora of which have already been generated by the community. We report that NanoDam single copy transgenes consisting of lowly expressed, tissue-specific GFP nanobody-Dam fusions, when combined with endogenous GFP-tagged alleles of TFs, results in robust, tissue-specific profiling. Using an endogenous GFP-tagged allele of EGL-43/EVI1, we performed NanoDam profiling of two disparate tissue types, the anchor cell (AC) and dopaminergic neurons, and identify targets unique to each and shared by both cell types. We also identify two GATA TFs, ELT-6 and EGL-18, as novel regulators of AC invasion. Taken together, we demonstrate that NanoDam is capable of profiling endogenous GFP-tagged TFs to identify novel downstream targets in specific cell types of C. elegans.
