(Submitter supplied) We performed ChIP-seq of Hsf1 under non heat shock, 5-minute heat shock and 120 minute heat shock conditions. We used the conditional chemical genetics approach known as “anchor away” (AA) to rapidly inactivate Hsf1. We coupled Hsf1-AA to and nascent RNA seq (NAC)-seq to define the genes whose expression depends on Hsf1 during heat shock.

(Submitter supplied) Thermotolerance is a crucial virulence attribute for Cryptococcus neoformans, which causes fatal fungal meningitis in humans. A protein kinase, Sch9, suppresses the thermotolerance of C. neoformans but its regulatory mechanism remains unknown. Here we elucidated the Sch9-dependent and -independent signaling networks for modulating the thermotolerance of C. neoformans through a genome-wide transcriptome analysis and reverse genetics approaches. more...

(Submitter supplied) Heat shock transcription factors HSF1 and HSF2 both are necessary for proper spermatogenesis, which is disrupted at elevated temperatures. We studied how HSF1 and HSF2 cooperate during the heat shock response in mouse spermatocytes. For this purpose we used ChIP-sequencing. ChIP-Seq analyses revealed that the temperature elevation induces remodeling of HSF1 and HSF2 binding to chromatin. The highest HSF1-chromatin binding was observed at 43°C, when HSF2-chromatin binding was reduced. more...

(Submitter supplied) We used the conditional chemical genetics approach known as “anchor away” (AA) to rapidly inactivate the essential yeast transcription factor Hsf1. We coupled Hsf1-AA to RNA-seq and NET-seq to define the genes whose expression depends on Hsf1 and performed Hsf1-3xFLAG-V5 ChIP-seq to validate direct targets. We also carried out a number of other perturbations to yeast stress pathways to show that most of the gene expression changes during heat shock are Hsf1-independent but depend on PKA signaling and the Msn2/4 general stress transcription factors. more...

(Submitter supplied) Heat shock (HS) causes dramatic and rapid changes in transcription of thousands of genes in metazoans. We have used insitu Hi-C in Drosophila S2 and human K562 cells to determine the effects of HS upon chromatin conformation. Our study shows that topologically associated domains (TADs), compartments and distal regulatory interactions remain unchanged upon HS.

(Submitter supplied) Heat shock response (HSR) is critical for survival of organisms undergoing proteotoxic stress. Heat shock factor 1 (HSF1) is widely believed to be the master regulator of this response. Here, we examined the kinetics of the transcriptional response and HSF1 binding changes genome-wide after heat shock (HS) with high sensitivity and high spatial and temporal resolution using PRO-seq and ChIP-seq assays respectively in wild type and in hsf1-deletion mouse embryonic fibroblasts. more...

(Submitter supplied) In somatic cells elevated temperature induces activation of the heat shock transcription factor 1 (HSF1) what leads to heat shock proteins synthesis and cytoprotection. However, in the male germ cells (spermatocytes) upon HSF1 activation, caspase-3 dependent apoptosis is induced and spermatogenic cells are actively eliminated. To find out molecular targets of HSF1 in all promoter regions, and to elucidate a mechanism of such diverse HSF1 activity we carried out genome-wide HSF1 binding analysis in control and heat-shocked cells, either spermatogenic or somatic. more...

(Submitter supplied) Effect of hsf1-R206S/F256S mutation on heat-induced transcription of genes is analyzed. Total RNA was isolated from HSF1 wild type and hsf1-R206S/F256S cells grown at 39oC for 15 min. Probe cDNA was primed by oligo(dT) and was synthesized in the presence of 33P-dCTP. Hybridization was carried out using the same GF100 GeneFilter. Value higher than 30 in HSF1 wild type cells is confident. Values from duplicate experiments were averaged, and the average fold changes were calculated. more...

(Submitter supplied) We investigated whether interfering with HSF1 LLPS affected the expression of its target genes using RNA sequencing. We found HS induced HSPs gene expression in LLPS-dependent manner. LLPS-dependent gene activation was also observed in M1 cells under NHS condition. In addition, LLPS-incompetent M3 infected cells showed less HSP gene expression even under HS condition. Thus, these data collectively support a crucial role for LLPS of HSF1 in activating HSP genes expression.

(Submitter supplied) Heat Shock Factor 1 (Hsf1) in yeast drives the basal transcription of key proteostasis factors and its activity is induced as part of the core heat shock response. In this study we stringently test the role of Hsf1 under basal and stress conditions using a newly constructed hsf1∆ strain. To assess how cells mount transcriptional stress responses when Hsf1 is inactivated, we performed mRNA-sequencing (mRNA-seq) upon hear shock (HS) or treatment with azetidine-2-carboxylic acid (AzC).

(Submitter supplied) HSF1 is a major transcriptional regulator of heat shock responses. Many cells activate HSF1 in response to heat shock temperatures (>42oC) and other cellular stress causing agents. Unlike other cell types, T cells activate HSF1 in response to T cell activation or when exposed to febrile (40oC) temperatures, suggesting a role for HSF1 beyond the heat-shock response. We used microarray analysis and HSF1 knock-out mice to study the HSF1 mediated gene regulation in activated T cells under normal and fever temperatures.
