Aging has been associated with a progressive decline of proteostasis, but how this process affects proteome composition remains largely unexplored. Here, we profiled more than 5,000 proteins along the lifespan of the nematode C. elegans. We find that one-third of proteins change in abundance at least 2-fold during aging, resulting in a severe proteome imbalance. These changes are reduced in the long-lived daf-2 mutant but are enhanced in the short-lived daf-16 mutant. While ribosomal proteins de ...[more]

Project description:Upon heat shock, Hsf1 protein is extensively phosphorylated, however, this modification is inhibited by an hsf1-bal mutation. To get genome-wide effect of the hyperphosphorylation on Hsf1-regulated transcription, the heat-induced gene expression profiles in HSF1 and hsf1-bal cells were compared. Keywords: stress response

Project description:HuntingtonM-bM-^@M-^Ys disease (HD) is a neurodegenerative disorder that is associated with the deposition of proteinaceous aggregates in the brains of HD patients and mouse models. Previous studies have suggested that wide-scale disruption of protein homeostasis occurs in protein folding diseases. Protein homeostasis can be maintained by activation of the heat shock response (HSR) via the transcription factor heat shock factor 1 (HSF1), the pharmacological activation of which can be achieved by Hsp90 inhibition and has been demonstrated to be beneficial in cell and invertebrate models of HD. Whether the HSR is functional in HD and whether its activation has therapeutic potential in mammalian HD models is currently unknown. To address these issues, we used a novel, brain penetrant Hsp90 inhibitor to activate the HSR in brain after systemic administration. Microarrays, quantitative PCR and western blotting showed that the HSR becomes impaired with disease progression in two mouse models of HD and that this originates at the level of transcription.

Microarray quality control was performed using the software package provided on RACE (http://race.unil.ch).

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.

Project description:Stress responses are a key feature of normal physiology and are usurped by cancer cells to ensure enhanced protein synthesis for growth, to compensate for genomic instability, and to protect cancer cells from therapy induced stress. Heat shock factor-1 (HSF1) is a major stress-response transcription factor, and its activity is markedly enhanced in cancer. Stress induces HSF1 conformational changes and post-translational modifications, leading to assembly of active HSF1 trimers that bind DNA to control target gene expression. Although the function of HSF1 in transcription is relatively well-known, the mechanisms leading to HSF1 activation and enhanced stress response in tumours are unclear. To investigate whether HSF1 is a primary sensor of proteotoxic stress in vivo, we studied the range of conditions that can cause HSF1 activation in vitro and in cells, and conditions that prevent its activation. We show that purified recombinant HSF1 adopts a stable monomeric conformation in vitro. Heat stress caused a conformational change and the assembly of HSF1 trimers. Conditions leading to protein denaturation, including heat stress, crowding, Hsp90 inhibition, or proteasome inhibition, all directly lead to HSF1 activation. In contrast, HSF1 activation in vivo is prevented by proteosynthesis inhibition, which reduces the amount of denatured proteins in the cell. These results establish that HSF1 is a direct sensor of proteotoxic stress, independent of post-translational modification, where abrupt environmental changes that cause protein denaturation simultaneously induce a conformational change in monomeric HSF1 leading to its activation. This mechanism explains the universal ability of cells to respond to proteotoxic stress and trigger a protective response when increased chaperone activities are required to restore homeostasis.

Project description:Maintaining proteostasis is key to resisting stress and to promoting healthy aging. Proteostasis is necessary to preserve stem cell function, but little is known about the mechanisms that regulate proteostasis during stress in stem cells, and whether disruptions in proteostasis contribute stem cell aging is largely unexplored. We determined that ex vivo cultured mouse and human hematopoietic stem cells (HSCs) rapidly increase protein synthesis. This challenge to HSC proteostasis was associated with nuclear accumulation of Hsf1, and deletion of Hsf1 impaired HSC maintenance ex vivo. Strikingly, supplementing cultures with small molecules that enhance Hsf1 activation partially suppressed protein synthesis, rebalanced proteostasis, and supported retention of HSC serial reconstituting activity. Although Hsf1 was dispensable for young adult HSCs in vivo, Hsf1 deficiency increased protein synthesis and impaired the reconstituting activity of middle-aged HSCs. Hsf1 thus promotes proteostasis and the regenerative activity of HSCs in response to culture stress and aging.
