All Roads Lead to ATF4 [PDF]

open access: yesDevelopmental Cell, 2003
Multiple intracellular stress pathways converge on a single event--phosphorylation of the translation initiation factor eIF2alpha and subsequent translational activation of the transcription factor ATF4. Exploring the consequences of this event has highlighted the ways in which stress is sensed and responded to via many distinct pathways.

Regulation of Nrf2 by Mitochondrial Reactive Oxygen Species in Physiology and Pathology

open access: yesBiomolecules, 2020
Reactive oxygen species (ROS) are byproducts of aerobic respiration and signaling molecules that control various cellular functions. Nrf2 governs the gene expression of endogenous antioxidant synthesis and ROS-eliminating enzymes in response to various ...

ATF4-sensitive genes and biological pathways.

open access: yes, 2023
(A) Gene ontology biological process enrichment analysis for genes with a TSS-proximal ATF4 peak called in ≥4 cell types (out of the 7 analyzed). One ChIP-Seq library was used to represent each cell type (the library with the most peaks called).

open access: yes, 2021
Representative immunofluorescent images of 8-week-old OLETF and LETO rats in the anterior cingulate cortex (ACC; A, B, C and D), basolateral amygdala (BLA; E, F, G, and H), and hippocampal cornu ammonis area 3 (CA3; I, J, K, and L.

ATF4- and PV-positive neurons in the corticolimbic system.

open access: yes, 2021
Representative immunofluorescent images of 8-week-old OLETF and LETO rats in the prelimbic cortex (PL; A, B, C and D), basolateral amygdala (BLA; E, F, G, and H), and hippocampal cornu ammonis area 3 (CA3; I, J, K, and L).

High ATF4 Expression Is Associated With Poor Prognosis, Amino Acid Metabolism, and Autophagy in Gastric Cancer

open access: yesFrontiers in Oncology, 2021
BackgroundThe role of activating transcription factor 4 (ATF4) underlying gastric cancer (GC) remains unclear. The purpose of this study was to investigate the expression levels and biological functions of ATF4 in GC.MethodsExpression of ATF4 was ...

ATF4 and HIF-1α in bone: An intriguing relationship [PDF]

open access: yesJournal of Bone and Mineral Research, 2013
As occurs in any other vascularized organ, one of the essential functions of blood vessels in bone is to be a source of O2, nutrients, hormones and growth factors (1). However, additional roles for bone blood vessels are emerging. For example, osteoblast precursors have been recently identified within their wall (2,3), which suggests that blood vessels

Dynamic induction of drug resistance through a stress-responsive enhancer in acute myeloid leukemia

open access: yesMolecular & Cellular Oncology, 2020
The drug efflux pump ABCB1 (ATP binding cassette subfamily B member 1) confers chemotherapy resistance in acute myeloid leukemia (AML). We recently identified an ABCB1 enhancer that is activated in response to a range of cellular stressors, including ...

Elucidation of an mTORC2-PKC-NRF2 pathway that sustains the ATF4 stress response and identification of Sirt5 as a key ATF4 effector

open access: yesCell Death Discovery, 2022
AbstractProliferating cancer cells are dependent on glutamine metabolism for survival when challenged with oxidative stresses caused by reactive oxygen species, hypoxia, nutrient deprivation and matrix detachment. ATF4, a key stress responsive transcription factor, is essential for cancer cells to sustain glutamine metabolism when challenged with these
