ATF4 Responds to Metabolic Stress in Drosophila
Background: Activating transcription factor 4 (ATF4) is a fundamental basic-leucine zipper transcription factor that plays a pivotal role in numerous stress responses, including endoplasmic reticulum (ER) stress and the integrated stress response.

The stress-induced transcription factor ATF4 has multiple conserved retrocopies that can alter gene expression [PDF]
Summary: The cell must defend against various stressors from internal and external sources that disrupt cell homeostasis. The integrated stress response (ISR) is a highly conserved pathway that helps restore this homeostasis through upregulating the ...

PRMT5 regulates ATF4 transcript splicing and oxidative stress response
Protein methyltransferase 5 (PRMT5) symmetrically dimethylates arginine residues leading to regulation of transcription and splicing programs. Although PRMT5 has emerged as an attractive oncology target, the molecular determinants of PRMT5 dependency in ...

Integrative single-cell and bulk analyses reveal ATF4-associated immune suppression and WNT/β-catenin signaling in osteosarcoma [PDF]
Background Osteosarcoma (OS) is highly heterogeneous and often exhibits an immunosuppressive tumor microenvironment, contributing to poor outcomes. The cell-type-resolved role of the ATF/CREB stress-response network, particularly ATF4, remains unclear in

Cardioprotective effect of Ginger in a rat model of myocardial damage and its possible intervention in PERK-ATF4-CHOP-PUMA apoptotic pathway [PDF]
For today the exact mechanisms of myocardial infarction and ischemia/reperfusion injury are still not fully understood. ER stress and integrated stress response pathways are thought to play an essential role in myocardial damage. This includes activation

GCN2 upregulates autophagy in response to short-term deprivation of a single essential amino acid
The ability to adapt the proteolysis rates based on fluctuations in essential amino acid (EAA) availability is essential for life. The GCN2-eIF2α-ATF4 signaling pathway is involved in the adaptive response to EAA deprivations.

Promoter methylation and expression pattern of DLX3, ATF4, and FRA1 genes during osteoblastic differentiation of adipose-derived mesenchymal stem cells [PDF]
Introduction: Nowadays, mesenchymal stem cells are touted as suitable cell supply for the restoration of injured bone tissue. The existence of osteogenic differentiation makes these cells capable of replenishing damaged cells in the least possible time ...
