(Submitter supplied) Purpose: We used RNA-Seq to compare the gene expression profiles in two long-lived C. elegans strains: (1) animals with a loss-of-function mutation in the hsb-1 gene, and (2) animals overexpressing hsf-1 under its endogenous promoter. Previous studies indicated that life span extension in both these strains is hsf-1-dependent. Methods: mRNA-Seq profiles for three biological replicates each of day 1 adult wild-type (N2 strain), hsb-1 mutant and hsf-1 overexpression strains were generated using 50 bp single-end sequencing on an Illumina HiSeq 2500 platform. more...

(Submitter supplied) Heat shock factor 1 (HSF-1) and forkhead box O (FOXO) are key transcription factors that protect cells from various stresses. InCaenorhabditis elegans, HSF-1 and FOXO together promote a long life span when insulin/IGF-1 signaling (IIS) is reduced. However, it remains poorly understood how HSF-1 and FOXO cooperate to confer IIS-mediated longevity. Here, we show that prefoldin 6 (PFD-6), a component of the molecular chaperone prefoldin-like complex, relays longevity response from HSF-1 to FOXO under reduced IIS. more...

(Submitter supplied) We report the transcritional targets of transcription factor downstream of insulin signalling. We knocked down transcription factors under reduced insulin signalling in Caenorhabditis elegans and did transcriptom analysis. This study identified target genes interaction complexity in analogous genetic and experimental conditions. It aid in gaining insight into the new molecular mechanisms downstream of rIIS

(Submitter supplied) To mitigate the deleterious effects of temperature increases on cellular organization and proteotoxicity, organisms have developed mechanisms to respond to heat stress. In eukaryotes, HSF1 is the master regulator of the heat shock transcriptional response, but the heat shock response pathway is not yet fully understood. From a forward genetic screen for suppressors of heat shock induced gene expression in Caenorhabditis elegans, we found a new allele of hsf-1 that alters its DNA-binding domain, and we found three additional alleles of sup-45, a previously molecularly uncharacterized genetic locus. more...

(Submitter supplied) FoxO transcription factors promote longevity across taxa. How they do so is poorly understood. In the nematode Caenorhabditis elegans, the A- and F-isoforms of the FoxO transcription factor DAF-16 extend life span in the context of reduced DAF-2 insulin-like growth factor receptor (IGFR) signaling. To elucidate the mechanistic basis for DAF-16/FoxO-dependent life span extension, we performed an integrative analysis of isoform-specific daf-16/FoxO mutants. more...

(Submitter supplied) To understand the roles of HSF-1 and its regulation in reproduction and heat shock response in a tissue-specific manner, we coupled tissue-specific HSF-1 depletion in C. elegans by auxin-inducible degron (AID) with genome-wide transcriptional analyses in whole animals. We used ChIP-seq to analyze the occupancy of HSF-1 (tagged with AID::GFP) and RNA Pol II in young adult (YA) animals grown at 20°C or upon heat shock (HS) at 34°C for 30 min following an acute depletion of HSF-1 by AID for 2 hours either in the somatic or in the germline cells. more...

(Submitter supplied) We have identified a role of the C. elegans miR-83 in regulating lifespan. mir-83 mutants exhibit an extended lifespan, and its overexpression is sufficient to decrease the prolonged lifespan of the mutants. We observed an upregulation in the expression of sets of miR-83 targets in young mir-83 mutant adults. However, in older mir-83 mutant adults, a different set of genes are upregulated. In vivo assays show that miR-83 regulates expression of a number of targets, including din-1, spp-9 and col-178. more...

(Submitter supplied) Aging and the age-associated decline of the proteome is determined in part through neuronal control of evolutionarily conserved transcriptional effectors, which safeguard homeostasis under fluctuating metabolic and stress conditions by regulating an expansive proteostatic network. We have discovered the Caenorhabditis elegans homeodomain-interacting protein kinase (HPK-1) acts as a key transcriptional effector to preserve neuronal integrity, function, and proteostasis during aging. more...
