Project description:Analysis of HSF1-down regulation of HCC cells at gene expression level. Results provide important information of genes involved in HSF1, such as liver proliferation, apoptosis, stress response, metabolism, these genes were up- or down-regulated. Total RNA obtained from HSF1-KD KYN2 (HCC) cells and HSF1-control KYN2 cells. To identify genes generally involved in HSF1 associated, we compared expression profiles between HSF1-KD KYN2 (HCC) cells and HSF1-control KYN2 cells by using Illumina HumanWG-6 BeadChip.

Project description:To analyze target genes of human heat shock transcription factor 1 (HSF1), we first generated two independent HeLa clones (RDT1 and RDT2) expressing an actively mutated hHSF1 (hHSF1?RDT), which lacks the regulatory domain that masks its activation domain and possesses a glutamic acid at amino acid 395 instead of a leucine in the suppression domain of the trimerization domain (Fujimoto et al., J. Biol. Chem. 280, 34908-34916, 2005). We also generated a HeLa clone expressing chicken HSF1 (HeLa/cHSF1) to compare its profile of gene expression with those of RDT1 and RDT2 cells (Nakai and Morimoto, Mol. Cell. Biol. 13, 1983-1997, 1993). We then carried out DNA microarray analysis using total RNA isolated from HeLa, HeLa/cHSF1, RDT1, and RDT2 cells grown under normal growth conditions. mRNA levels in human HeLa, RDT1, RDT2, and HeLa/cHSF1 were analyzed by DNA microarray analysis using GeneChip Human Genome U133 Plus 2.0 Array (Affymetrix).

Project description:Identification of genes regulated by knockdown of HSF1 or RPA1
| PRJNA167801 | ENA
Project description:Heat shock transcription factor 1 (HSF1) is recognized as the major regulator of the heat shock transcriptional response, and also plays a central role in the cellular functions of cancer cells. Here, to identify the molecular mechanism by which HSF1 regulates the proliferation of cancer cells, comparative gene expression analysis was performed with mock and HSF1-knockdown cells. Silencing of HSF1 in human oral squamous cell carcinoma HSC-3 cells was carried out by siRNA technology and the expression of HSF1 was confirmed by Western blotting. Gene expression was analyzed using GeneChip oligonucleotide microarrays and computational gene expression analysis tools. HSF1 knockdown significantly decreased the number of viable cells. Of the 54,675 probe sets analyzed, 221 probe sets were up-regulated and 423 probe sets were down-regulated by >2-fold in HSF1-knockdown cells.

HSC-3 human oral squamous carcinoma cells were treated with siRNA for HSF1 or luciferase. Total RNA samples were prepared from the cells. Gene expression was analyzed by an Affymetrix GeneChipM-BM-. system with a Human Genome U133-plus 2.0 array. Sample preparation for array hybridization was carried out as described in the manufacturerM-bM-^@M-^Ys instructions.

Project description:Although HSF1 is known to play an important role in regulating the cellular response to proteotoxic stressors, little is known about the structure and function of the HSF1 signaling network under both stressed and unstressed conditions. In this study, we used a combination of chromatin immunoprecipitation (ChIP) microarray analysis and time course gene expression microarray analysis with and without siRNA-mediated inhibition of HSF1 comprehensively identify genes directly and indirectly regulated by HSF1 and examine the structure of the extended HSF1 signaling network. Correlation between promoter binding and gene expression was not significant for all genes bound by HSF1 suggesting that HSF1 binding per se is not sufficient for expression. However, the correlation with promoter binding was significant for genes identified as HSF1-regulated following siRNA knockdown allowing the identification of direct transcriptional targets of HSF1. Among promoters bound by HSF1 following heat shock, a gene ontology (GO) analysis showed significant enrichment only in categories related to protein folding. In contrast, analysis of the extended HSF1 signaling network showed enrichment in a variety of categories related to protein folding, anti-apoptosis, RNA splicing, ubiquitination and others, highlighting a complex transcriptional program directly and indirectly regulated by HSF1.,SUBMITTER_CITATION: Genome-wide analysis of human HSF1 signaling reveals a transcriptional program linked to cellular adaptation and survival Authors: Todd J.
