A PDX1-ATF transcriptional complex governs β cell survival during stress

Molecular Metabolism, 2018
Objective: Loss of insulin secretion due to failure or death of the insulin secreting β cells is the central cause of diabetes. The cellular response to stress (endoplasmic reticulum (ER), oxidative, inflammatory) is essential to sustain normal β cell ...

The Effects of Angiotensin Receptor Neprilysin Inhibitor on Endoplasmic Reticulum Stress in Doxorubicin‐Mediated Cardiomyopathy‐Associated Heart Failure Model in Rats

Journal of Applied Toxicology, EarlyView.
ABSTRACT One of the most serious complications associated with the use of the chemotherapeutic agent doxorubicin (DOX) is cardiomyopathy. Although cardioprotective drugs such as angiotensin receptor‐neprilysin inhibitors (ARNI) are used to prevent cardiomyopathy in DOX patients, no studies have reported the relationship between ARNI and endoplasmic ...

Stem-loop-induced ribosome queuing in the uORF2/ATF4 overlap fine-tunes stress-induced human ATF4 translational control

Cell Reports
Summary: Activating transcription factor 4 (ATF4) is a master transcriptional regulator of the integrated stress response, leading cells toward adaptation or death.

Bisphenol Analog‐Induced Cytotoxicity: Unraveling Endoplasmic Reticulum (ER) Stress and Apoptotic Pathways

Journal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA) is increasingly replaced by structural analogs, yet their safety remains insufficiently characterized. This study investigated whether BPA and selected analogs, bisphenol AF (BPAF), bisphenol AP (BPAP), bisphenol P (BPP), and bisphenol E (BPE), induce cytotoxicity through activation of endoplasmic reticulum (ER) stress and ...

Roles of activation transcription factor 4 (ATF4) and YrdC in the response of vascular smooth muscle cells to injury

, 2008
Neointimal proliferation is a key process underlying many cardiovascular diseases such as atherosclerosis and angioplasty-induced restenosis. Vascular smooth muscle cells (SMC) are significant contributors to the development and stability of the neointimal lesion.

The bidirectional regulatory network between ATF4 and lncRNAs in systemic diseases

Frontiers in Oncology
Long non-coding RNAs (lncRNAs) are pivotal regulators of gene expression across multiple biological contexts, including stress responses and cellular adaptation. Activating transcription factor 4 (ATF4) is a key transcriptional effector of the integrated

Air Pollution Quinones Impair Intestinal Barrier Integrity and Endoplasmic Reticulum in Differentiated Caco‐2 Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Particulate matter (PM) is a major global health threat, linked to millions of deaths annually. Beyond inhalation, PM components reach the gastrointestinal tract through the mucociliary escalator or contaminated food and water. Among PM's organic fraction, redox‐active quinones such as 1,2‐naphthoquinone (NQ) and 9,10‐phenanthrenequinone (PQ ...

ATF4 inhibits tumor development and mediates p-GCN2/ASNS upregulation in colon cancer

Scientific Reports
Colon cancer (CC) is a highly malignant tumor with a high incidence and poor prognosis. This study aimed to explore the function and molecular mechanisms of activating transcription factor 4 (ATF4) in CC.

FAM175B promotes apoptosis by inhibiting ATF4 ubiquitination in esophageal squamous cell carcinoma

Molecular Oncology, 2019
FAM175B is a reported regulator of p53 and suppresses tumorigenesis in numerous types of cancer, but very little is known about its function in esophageal squamous cell carcinomas (ESCCs), almost 70% of which exhibit mutations in p53.

Improving protein secretion with autophagy‐inhibiting or proteasome‐activating small molecules

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Therapeutic proteins are produced frequently by mammalian cells in large‐scale bioreactors. As a result, producer cells are exposed to a chemically (nutrients, gas exchange, target protein overexpression) and physically (shear due to mixing) stressful environment, which can lead to endoplasmic reticulum (ER) stress and loss of ...
