In vitro activation of heat shock transcription factor by 4-hydroxynonenal

Chemico-Biological Interactions, 1992
In the activation of eukaryotic heat shock genes, the acquisition of a binding ability to specific DNA sequence by a transcriptional activator, heat shock factor (HSF), is believed to be a crucial step. The induction of this new DNA binding activity of HSF is also obtained in a cell-free system (in vitro activation) by hyperthermia or at physiological ...

Activation transcription factor-4 and the acute vascular response to injury

Journal of Molecular Medicine, 2010
Atherosclerosis is a complex fibroproliferative-inflammatory process triggered by vascular injury. Transcription factors play an important role in the control of genes that effect critical changes in the vessel wall. Recent evidence indicates an emerging role for activation transcription factor 4 (ATF4), a master regulator for evolutionarily conserved ...

Regulation of FGF-4 Enhancer Activity by Transcription Factor NF-Y

Biochemical and Biophysical Research Communications, 1995
Regulation of FGF-4 gene expression is controlled both by elements in the promoter and by an enhancer domain located in the untranslated region of the third exon. We have determined that transcription factor NF-Y binds to the FGF-4 promoter. We further show by mutational analysis that binding of NF-Y is essential for FGF-4 enhancer activity but has ...

SUMOylation can regulate the activity of ETS-like transcription factor 4

Biochimica et Biophysica Acta (BBA) - Gene Regulatory Mechanisms, 2010
ETS-like transcription factor 4 (ELK4) (a.k.a. serum response factor accessory protein 1) belongs to the ternary complex factor (TCF) subfamily of E twenty-six (ETS) domain transcription factors. Compared to the other TCF subfamily members, ELK1 and ELK3 (NET), there is limited information of the mechanisms regulating the ELK4 activity.

Effects of activating transcription factor 4 deficiency on carbohydrate and lipid metabolism in mammals

IUBMB Life, 2012
AbstractIt has been shown that the mammalian activating transcription factor 4 (ATF4) is involved in many different physiological events, such as eye development, stress response, learning, and memory. However, several recent studies have demonstrated that ATF4 also plays an important role in the regulation of lipid and glucose metabolism, energy ...

Activating Transcription Factor 4 Modulates BDNF Release from Microglial Cells

Journal of Molecular Neuroscience, 2013
Pathogenic pain is a common sign of many diseases. The mechanism is unclear. Activating transcription factor 4 (ATF4) plays a critical role in cell activation. Brain-derived neurotrophic factor (BDNF) is an important molecule in pathogenic pain. This study aims to investigate the role of ATF4 in inducing BDNF release from microglial cells.

Short Communication: Activating Transcription Factor 4 (ATF4) Promotes HIV Type 1 Activation

AIDS Research and Human Retroviruses, 2012
Activating transcription factor 4 (ATF4) is a central factor in the cellular response to multiple stresses, including altered metabolic conditions, anoxia and hypoxia, and redox stress. ATF4 is triggered by endoplasmic reticulum stress and consequent unfolded protein response.

Interaction Between Activating Transcription Factor 4 and Interleukin 6 Dictates Osteoclast Differentiation and Activity

The FASEB Journal
ABSTRACT Osteoclast functioning determines homeostasis of bone texture, healing speed after bone injury, and integrity after bone remodeling. Osteoclastogenesis is tightly controlled by transcriptional factors and cytokine‐mediated signaling.

Activating transcription factor 4-dependent induction of FGF21 during amino acid deprivation

Biochemical Journal, 2012
Nutrient deprivation or starvation frequently correlates with amino acid limitation. Amino acid starvation initiates a signal transduction cascade starting with the activation of the kinase GCN2 (general control non-derepressible 2) phosphorylation of eIF2 (eukaryotic initiation factor 2), global protein synthesis reduction and increased ATF4 ...
