Activating Transcription Factor 4 (ATF4) Modulates Post-synaptic Development and Dendritic Spine Morphology

Frontiers in Cellular Neuroscience, 2014
The ubiquitously expressed activating transcription factor 4 (ATF4) has been variably reported to either promote or inhibit neuronal plasticity and memory.

DNA binding and transcription activation specificity of hepatocyte nuclear factor 4 [PDF]

Nucleic Acids Research, 1998
Hepatocyte nuclear factor 4 (HNF-4) is an orphan intracellular receptor that appears to be a key factor in the regulation of energy metabolism. In order to gain greater understanding of the binding and activation requirements of HNF-4, we performed genetic analysis of the apoCIII promoter, a promoter that has previously been shown to be highly ...

The Effect of Resistance Training and Berberine Chloride on the Apoptosis-related Unfolded Protein Response Signaling Pathway in the Hippocampus of Diazinon-poisoned Rats

Basic and Clinical Neuroscience, 2021
Introduction: Diazinon is one of the most widely-used organophosphate pesticides in the world. This toxin enters the body in various ways and induces oxidative stress in various tissues.

ATF4 selectively regulates heat nociception and contributes to kinesin-mediated TRPM3 trafficking

Nature Communications, 2021
The molecular mechanisms mediating nociception are unclear. Here, the authors show that the Activating Transcription Factor 4 (ATF4) is important for the response to heat nociception in mice and ATF4 role in mediating protein trafficking in dorsal root ...

OPA1 deletion in brown adipose tissue improves thermoregulation and systemic metabolism via FGF21

eLife, 2021
Adrenergic stimulation of brown adipocytes alters mitochondrial dynamics, including the mitochondrial fusion protein optic atrophy 1 (OPA1). However, direct mechanisms linking OPA1 to brown adipose tissue (BAT) physiology are incompletely understood.

Inhibition of hepatocyte nuclear factor 4 transcriptional activity by the nuclear factor κB pathway [PDF]

Biochemical Journal, 2006
HNF-4 (hepatocyte nuclear factor 4) is a key regulator of liver-specific gene expression in mammals. We have shown previously that the activity of the human APOC3 (apolipoprotein C-III) promoter is positively regulated by the anti-inflammatory cytokine TGFβ (transforming growth factor β) and its effectors Smad3 (similar to mothers against ...

The Metabotropic GABAB Receptor Directly Interacts with the Activating Transcription Factor 4 [PDF]

Journal of Biological Chemistry, 2000
G protein-coupled receptors regulate gene expression by cellular signaling cascades that target transcription factors and their recognition by specific DNA sequences. In the central nervous system, heteromeric metabotropic gamma-aminobutyric acid type B (GABA(B)) receptors through adenylyl cyclase regulate cAMP levels, which may control transcription ...

Activating transcription factor 4 confers a multidrug resistance phenotype to gastric cancer cells through transactivation of SIRT1 expression. [PDF]

PLoS ONE, 2012
BACKGROUND: Multidrug resistance (MDR) in gastric cancer remains a major challenge to clinical treatment. Activating transcription factor 4 (ATF4) is a stress response gene involved in homeostasis and cellular protection.

Effect of leucine on endoplasmic reticulum stress induced by early weaning in the liver of piglets

浙江大学学报. 农业与生命科学版, 2018
To investigate the effects of dietary leucine supplementation on endoplasmic reticulum (ER) stress in the liver of early-weaning piglets, we explored the morphology of liver cells, expression pattern of ER stress-associated proteins, and effects on ER ...
