The development of nonalcoholic fatty liver disease (NAFLD) is associated with increased reactive oxygen species (ROS) production. Previous observations on the contradictory roles of general control nonderepressible 2 (GCN2) in regulating the hepatic ...

Dengue Virus Induced COX-2 Signaling Is Regulated Through Nutrient Sensor GCN2
Nutrient sensor GCN2 plays a crucial role in the maintenance of cellular homeostasis during the condition of amino acid deprivation. Dysfunction in the GCN2 signaling underlies several chronic metabolic diseases.

RAF inhibitors activate the integrated stress response by direct activation of GCN2 [PDF]
Paradoxical activation of wild type RAF by chemical RAF inhibitors (RAFi) is a well-understood ‘on-target’ biological and clinical response. In this study, we show that a range of RAFi drive ERK1/2-independent activation of the Unfolded Protein Response (

GCN2 enhances host survival and drives eIF2α phosphorylation during mouse adenovirus type 1 infection [PDF]
The integrated stress response (ISR) is a cellular signaling pathway that reduces protein synthesis in the face of cellular stress, including viral infection. Two eukaryotic initiation factor 2α (eIF2α) kinases, protein kinase R (PKR) and general control

GCN2 is activated by methyl jasmonate through GCN1 and reactive oxygen species in Arabidopsis thaliana [PDF]
Plant growth and productivity rely on rapid energy management strategies to adapt dynamic environments. Previous work in Arabidopsis thaliana identified a fast-regulatory switch linking cytosolic translation and reactive oxygen species (ROS) signaling ...

Downhill running regulates cardiac immune response through GCN2. [PDF]
Downhill running (DR) has recently emerged as a promising exercise modality for cardiac rehabilitation, but the effect and mechanism of DR on myocardium remains unclear. General control nonderepressible 2 (GCN2), an eukaryotic initiation factor 2α (eIF2α)

A genetic approach to identify amino acids in Gcn1 required for Gcn2 activation.
The protein kinase Gcn2 is present in virtually all eukaryotic cells. It is best known for its role in helping cells cope with amino acid starvation. Under starvation, Gcn2 phosphorylates the α subunit of the eukaryotic translation initiation factor 2 ...

The antitumor activity of a novel GCN2 inhibitor in head and neck squamous cell carcinoma cell lines
Background: General control nonderepressible 2 (GCN2) senses amino acid deprivation and activates activating transcription factor 4 (ATF4), which regulates many adaptive genes. We evaluated the impact of AST-0513, a novel GCN2 inhibitor, on the GCN2-ATF4

Modulation of GCN2 activity under excess light stress by osmoprotectants and amino acids
The protein kinase GCN2 (General Control Nonderepressible2) and its phosphorylation target, the eukaryotic translation initiation factor (eIF)2α represent the core module of the plant’s integrated stress response, a signaling pathway widely conserved in ...
