Project description:The wild type (WT) and HSP-1 EEYD (worms generating endogenously mutated HSP-1) C. elegans were cultured under normal conditions (20 degrees) or exposed to 30 degrees for 16 hours as L4 larvae (referred to as heat stress/HS). In WT worms undergoing HS, the activity of CHN-1 ubiquitin ligase is anticipated to be inhibited by its interaction with wild-type HSP-1. In contrast, HSP-1 EEYD is expected not to inhibit CHN-1 in mutant worms, consequently leading to the degradation of a specific pool of proteins. This dataset unveils the identities of these proteins.

Project description:modENCODE_submission_4807 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.

Project description:Sexual dimorphism affects diverse biological functions such as immune responses. However, mechanisms by which different sexes alter immunity remained largely unknown. By using Caenorhabditis elegans as a model, here we show that male animals exhibit enhanced immunity against various pathogenic bacteria via upregulating autophagy. We found that male C. elegans displayed upregulation of helix loop helix 30 (HLH-30)/transcription factor EB (TFEB), a transcription factor crucial for autophagy, which contributed to the enhanced anti-bacterial immunity. We showed that autophagy-related protein 2 (atg-2) that is upregulated by HLH-30/TFEB, mediated increased immunity in male animals. Thus, male C. elegans appear to be equipped with enhanced autophagy for increasing pathogen resistance, likely conferring prolonged mate search with less infection.

Project description:Accumulating evidence has demonstrated the presence of inter-tissue communication regulating systemic aging, but the underlying molecular network has not been fully explored. We and others previously showed that two basic helix-loop-helix transcription factors, MML-1 and HLH-30, are required for lifespan extension in several longevity paradigms, including germline-less Caenorhabditis elegans. However, it is unknown what tissues these factors target to promote longevity. Here, using tissue-specific knockdown experiments, we found that MML-1 and its heterodimer partners MXL-2 and HLH-30 act primarily in neurons to extend longevity in germline-less animals. Neuronal functions of MML-1/MXL-2 and HLH-30 are also essential to prevent aging in non-neuronal tissues, including muscle and the intestine. Interestingly, however, both the temporal requirement and the downstream function of MML-1 in neurons were distinct from those of HLH-30. MML-1 was active early, while HLH-30 functioned later in life to sustain longevity in germline-less animals. Moreover, neuronal RNA interference (RNAi)-based transcriptome analysis revealed that the glutamate transporter GLT-5 is a novel downstream target of MML-1 but not HLH-30. Furthermore, the MML-1–GTL-5 axis in neurons is critical to prevent an age-dependent collapse of proteostasis and increased oxidative stress through autophagy and peroxidase MLT-7, respectively, in long-lived animals. Collectively, our study revealed that systemic aging is regulated by a novel molecular network involving neuronal MML-1 function in both neural and peripheral tissues.
