Transient intracellular acidification regulates the core transcriptional heat shock response
Heat shock induces a conserved transcriptional program regulated by heat shock factor 1 (Hsf1) in eukaryotic cells. Activation of this heat shock response is triggered by heat-induced misfolding of newly synthesized polypeptides, and so has been thought ...

Is there a role for HSF1 in viral infections?
Cells undergo numerous processes to adapt to new challenging conditions and stressors. Heat stress is regulated by a family of heat shock factors (HSFs) that initiate a heat shock response by upregulating the expression of heat shock proteins (HSPs ...

Heat shock response in archaea [PDF]
An adequate response to a sudden temperature rise is crucial for cellular fitness and survival. While heat shock response (HSR) is well described in bacteria and eukaryotes, much less information is available for archaea, of which many characterized species are extremophiles thriving in habitats typified by large temperature gradients.

Deteriorated stress response in stationary-phase yeast: Sir2 and Yap1 are essential for Hsf1 activation by heat shock and oxidative stress, respectively. [PDF]
Stationary-phase cultures have been used as an important model of aging, a complex process involving multiple pathways and signaling networks. However, the molecular processes underlying stress response of non-dividing cells are poorly understood ...

Transcriptomic Adaptation of Legionella pneumophila to Transient Heat Shock
A natural inhabitant of freshwater microbial ecology, Legionella pneumophila is an opportunistically pathogenic bacteria that has found a niche in hot water distribution systems (HWDS) where it challenges hospitals with the spread of nosocomial infection.

Drosophila heat shock response requires the jnk pathway and phosphorylation of mixed lineage kinase at a conserved serine-proline motif [PDF]
Defining context specific requirements for proteins and pathways is a major challenge in the study of signal transduction. For example, the stress-activated protein kinase (SAPK) pathways are comprised of families of closely related transducers that are ...

Systemic analysis of heat shock response induced by heat shock and a proteasome inhibitor MG132. [PDF]
The molecular basis of heat shock response (HSR), a cellular defense mechanism against various stresses, is not well understood. In this, the first comprehensive analysis of gene expression changes in response to heat shock and MG132 (a proteasome ...

Heat shock proteins in health and disease: therapeutic targets or therapeutic agents? [PDF]
For many years, heat shock or stress proteins have been regarded as intracellular molecules that have a range of housekeeping and cytoprotective functions, only being released into the extracellular environment in pathological situations such as necrotic
