    Molecular mechanism of thermosensory function of human heat shock transcription factor Hsf1

    Nikolai Hentze et al.
    Heat-induced local unfolding allows Hsf1 to form trimers and bind to DNA, which depends on Hsf1 concentration and is promoted, not inhibited, by Hsp90.

    The translation elongation factor eEF1A1 couples transcription to translation during heat shock response

    Maria Vera et al.
    Eukaryotic translation elongation factor 1A1 controls the process of heat shock response, from transcriptional activation of the HSP70 gene, to HSP70 mRNA stabilization, nuclear export, and translation.

    Cytoplasmic protein misfolding titrates Hsp70 to activate nuclear Hsf1

    Anna E Masser et al.
    Hsp70 restricts DNA binding activity of Hsf1 to control the width and amplitude of the heat-shock regulon.

    Endogenous siRNAs promote proteostasis and longevity in germline-less Caenorhabditis elegans

    Moran Cohen-Berkman et al.
    Endo-siRNAs slow down the rate of aging and enable the maintenance of a responsive heat shock response in aging germline-less Caenorhabditis elegans.

    Transient intracellular acidification regulates the core transcriptional heat shock response

    Catherine G Triandafillou et al.
    When translation stops, cells require intracellular acidification to turn on the conserved heat shock response during stress, and stress-triggered acidification (common in eukaryotes) is adaptive, promoting cell and population fitness.

    Diversification of the Caenorhabditis heat shock response by Helitron transposable elements

    Jacob M Garrigues et al.
    Helitron transposable elements, by providing high density transcription factor binding sites upstream of host genes, have diversified the heat shock response within and among Caenorhabditis species.

    A ribosome assembly stress response regulates transcription to maintain proteome homeostasis

    Benjamin Albert et al.
    Ribosome assembly is monitored to promote proteostatis through a system whereby unassembled ribosomal proteins lead to activation of heat shock factor 1 and inactivation of the RP gene activator Ifh1.

    Cell-based HTS identifies a chemical chaperone for preventing ER protein aggregation and proteotoxicity

    Keisuke Kitakaze et al.
    Cell-based high-throughput screening identifies IBT21 as a chemical chaperone, that inhibits ER protein aggregation and prevents the cell death caused by a proteotoxin, the aggregation-prone prion protein.

    Notch signalling maintains Hedgehog responsiveness via a Gli-dependent mechanism during spinal cord patterning in zebrafish

    Craig T Jacobs, Peng Huang
    Genetic analyses combining photoconvertible cell signalling reporters with gain- and loss-of function manipulations reveal a novel role for Notch signalling in controlling Hedgehog response in neural progenitor cells.

    Genome-wide identification of neuronal activity-regulated genes in Drosophila

    Xiao Chen et al.
    Activity-regulated genes in Drosophila neurons differ from the well-characterized situation in mammals, and these genes provided a strategy to construct reporters for monitoring neuronal activity in fly brains.
