Transcriptome analysis of Clematis lanuginosa: Novel features of the molecular events occurring under heat-shock stress

Ornamental Plant Research, 2022
The weak heat tolerance of Clematis ornamental varieties negatively affects their ornamental qualities in the summer. To elucidate heat resistance mechanisms, Clematis lanuginosa, which is an important original parent of the Clematis large-flowered group

Evidence for a heat shock transcription factor-independent mechanism for heat shock induction of transcription in Saccharomyces cerevisiae. [PDF]

Proceedings of the National Academy of Sciences, 1990
Transcription of the DNA damage-responsive gene, DDRA2, of Saccharomyces cerevisiae is activated by heat shock treatment as well as by mutagen/carcinogen exposure. Deletion analysis of upstream noncoding sequence indicated that sequences between approximately -190 and -140 base pairs were necessary for heat shock and DNA damage regulation of ...

Identifying transcription factors controlling the basal expression of human MRP4 highlights a substantial role for Sp1

FEBS Open Bio, EarlyView.
The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Heterotypic Signals from Neural HSF-1 Separate Thermotolerance from Longevity

Cell Reports, 2015
Integrating stress responses across tissues is essential for the survival of multicellular organisms. The metazoan nervous system can sense protein-misfolding stress arising in different subcellular compartments and initiate cytoprotective ...

Lipopolysaccharide uptake is augmented in lipopolysaccharide‐tolerant mouse macrophage‐like cells via increased CD14 expression

FEBS Open Bio, EarlyView.
In normal (nontolerant) cells, CD14 is crucial for both LPS uptake and LPS signaling. In LPS‐tolerant cells, in which LPS‐induced TNF‐α and IFN‐β production is suppressed, there is a dramatic increase in surface CD14 expression. The overexpressed CD14 in LPS‐tolerant cells is responsible for the enhanced LPS uptake without inducing pro‐inflammatory ...

mTOR is essential for the proteotoxic stress response, HSF1 activation and heat shock protein synthesis. [PDF]

PLoS ONE, 2012
The target of rapamycin (TOR) is a high molecular weight protein kinase that regulates many processes in cells in response to mitogens and variations in nutrient availability. Here we have shown that mTOR in human tissue culture cells plays a key role in

Heat shock transcription factor 1 preserves cardiac angiogenesis and adaptation during pressure overload [PDF]

, 2008
To examine how heat shock transcription factor 1 (HSF1) protects against maladaptive hypertrophy during pressure overload, we subjected HSF1 transgenic (TG), knockout (KO) and wild type (WT) mice to a constriction of transverse aorta (TAC), and found ...

Activation of heat shock transcription factor in yeast is not influenced by the levels of expression of heat shock proteins [PDF]

Molecular Microbiology, 2001
Heat shock transcription factor (HSF) transiently induces the expression of a universally conserved set of proteins, the heat shock proteins (Hsps), when cells are exposed to elevated temperatures as well as to a wide range of other environmental stresses.

Characterization of an Injectable Poly(vinyl alcohol)‐gelatin Hydrogel for Growth Factor Delivery in an Orthopedic Application

Advanced Healthcare Materials, EarlyView.
This work introduces photo‐crosslinkable tyraminated poly(vinyl alcohol)‐gelatin (PVA‐GT) hydrogels as tunable injectable platforms for tissue engineering and growth factor delivery applications. This schematic illustrates the two developed hydrogel formulations and the experimental workflow used to evaluate their physico‐chemical properties in vitro ...
