Functional contribution of the transcription factor ATF4 to the pathogenesis of amyotrophic lateral sclerosis. [PDF]
PLoS ONE, 2013 Endoplasmic reticulum (ER) stress represents an early pathological event in amyotrophic lateral sclerosis (ALS). ATF4 is a key ER stress transcription factor that plays a role in both adaptation to stress and the activation of apoptosis.

Dietary Methionine Restriction Regulates Liver Protein Synthesis and Gene Expression Independently of Eukaryotic Initiation Factor 2 Phosphorylation in Mice [PDF]
, 2017 Background: The phosphorylation of eukaryotic initiation factor 2 (p-eIF2) during dietary amino acid insufficiency reduces protein synthesis and alters gene expression via the integrated stress response (ISR).Objective: We explored whether a Met ...

DDX3 regulates endoplasmic reticulum stress-induced ATF4 expression [PDF]
Scientific Reports, 2017 AbstractAccumulation of unfolded and potentially toxic proteins in the endoplasmic reticulum (ER) activates a cell stress adaptive response, which involves a reprogramming of general gene expression. ATF4 is a master stress-induced transcription factor that orchestrates gene expression in cells treated with various ER stress inducers including those ...

Hop2 Interacts with ATF4 to Promote Osteoblast Differentiation [PDF]
Journal of Bone and Mineral Research, 2019 ABSTRACT Activating transcription factor 4 (ATF4) is a member of the basic leucine zipper (bZip) transcription factor family required for the terminal differentiation of osteoblasts. Despite its critical importance as one of the three main osteoblast differentiation transcription factors, regulators of osteoblast terminal maturation ...

ZIKV infection activates the IRE1-XBP1 and ATF6 pathways of unfolded protein response in neural cells. [PDF]
, 2018 BACKGROUND: Many viruses depend on the extensive membranous network of the endoplasmic reticulum (ER) for their translation, replication, and packaging. Certain membrane modifications of the ER can be a trigger for ER stress, as well as the accumulation ...

Targeting the ATF4 pathway in cancer therapy
Expert Opinion on Therapeutic Targets, 2012 Activating transcription factor 4 (ATF4) is a member of the activating transcription factor family. ATF4 expression is increased in response to a diverse array of microenvironmental stresses including amino acid depletion, oxidative stress and endoplasmic reticulum (ER) stress that are sensed by upstream eukaryotic translation initiation factor 2α ...
