(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) 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) To understand the function and regulation of the C. elegans heat shock factor (HSF-1) in larval development, we have used ChIP-seq to analyze the occupancy of HSF1 and RNA Pol II in L2 larvae and young adult (YA) animals grown at 20°C or upon heat shock at 34°C for 30 min. In addition, we have used RNA-seq to analyze the transcriptomes of wild type (N2), hsf-1(ok600) mutants and hsf-1(ok600); rmSi1[hsf-1::gfp] L2 larvae grown at 20°C and characterized the gene expression change by heat shock in wild type (N2) animals at L2 stage.

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) 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 observed that heat shock of Caenorhabditis elegans leads to the formation of nuclear double-stranded RNA (dsRNA) foci, detectable with a dsRNA-specific monoclonal antibody. These foci significantly overlap with nuclear HSF-1 granules. To investigate the molecular mechanism(s) underlying dsRNA foci formation, we used RNA-seq to globally characterize total RNA and immunoprecipitated dsRNA from control and heat-shocked worms. more...
