Role of activating transcription factor 4 in the hepatic response to amino acid depletion by asparaginase [PDF]
The anti-leukemic agent asparaginase activates the integrated stress response (ISR) kinase GCN2 and inhibits signaling via mechanistic target of rapamycin complex 1 (mTORC1).

Upregulation of the coagulation factor VII gene during glucose deprivation is mediated by activating transcription factor 4. [PDF]
BACKGROUND: Constitutive production of blood coagulation proteins by hepatocytes is necessary for hemostasis. Stressful conditions trigger adaptive cellular responses and delay processing of most proteins, potentially affecting plasma levels of proteins ...

Role of Activating Transcription Factor 4 in Murine Choroidal Neovascularization Model. [PDF]
Neovascular age-related macular degeneration (nAMD) featuring choroidal neovascularization (CNV) is the principal cause of irreversible blindness in elderly people in the world. Integrated stress response (ISR) is one of the intracellular signals to be adapted to various stress conditions including endoplasmic reticulum (ER) stress.

Activating transcription factor-4 promotes mineralization in vascular smooth muscle cells. [PDF]
Emerging evidence indicates that upregulation of the ER stress-induced pro-osteogenic transcription factor ATF4 plays an important role in vascular calcification, a common complication in patients with aging, diabetes, and chronic kidney disease (CKD).

Activating transcription factor 4: a regulator of stress response in human cancers [PDF]
Activating transcription factor 4 (ATF4) is an adaptive response regulator of metabolic and oxidative homeostasis. In response to cellular stress, ATF4 is activated and functions as a regulator to promote cell adaptation for survival.

Drosophila melanogaster activating transcription factor 4 regulates glycolysis during endoplasmic reticulum stress. [PDF]
AbstractEndoplasmic reticulum (ER) stress results from an imbalance between the load of proteins entering the secretory pathway and the ability of the ER to fold and process them. The response to ER stress is mediated by a collection of signaling pathways termed the unfolded protein response, which plays important roles in development and disease. Here
