Metabolic Dysfunction‐Associated Steatotic Liver Disease and Obesity: Pathogenesis, Diagnostics, Risk Stratification, and Therapeutic Approach

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Metabolic dysfunction‐associated steatotic liver disease (MASLD) has emerged as the most prevalent chronic liver disease worldwide, closely linked to the global rising incidence of obesity and metabolic syndrome. This review synthesizes current evidence on the pathogenesis, gut–liver axis, and multidisciplinary management of MASLD within the ...

Transmission of ER stress response by ATF6 promotes endochondral bone growth [PDF]

Journal of Orthopaedic Surgery and Research, 2015
We reported earlier that X-box binding protein1 spliced (XBP1S), a key regulator of the unfolded protein response (UPR), as a bone morphogenetic protein 2 (BMP2)-inducible transcription factor, positively regulates endochondral bone formation by activating granulin-epithelin precursor (GEP) chondrogenic growth factor.

Molecular mechanism of ATF6 in unfolded protein response and its role in disease

Heliyon
Activating transcription factor 6 (ATF6), an important signaling molecule in unfolded protein response (UPR), plays a role in the pathogenesis of several diseases, including diseases such as congenital retinal disease, liver fibrosis and ankylosing ...

CRISPR‐Based Gene Dependency Screens Reveal Mechanism of BRAF Inhibitor Resistance in Anaplastic Thyroid Cancer

Molecular Carcinogenesis, EarlyView.
ABSTRACT Anaplastic thyroid cancer (ATC) is the most aggressive form of thyroid cancer. Despite recent advances in treating BRAFV600E‐driven ATC, therapy resistance remains a significant challenge, often resulting in disease progression and death.

Transcription factor ATF4 directs basal and stress-induced gene expression in the unfolded protein response and cholesterol metabolism in the liver [PDF]

, 2016
Disturbances in protein folding and membrane compositions in the endoplasmic reticulum (ER) elicit the unfolded protein response (UPR). Each of three UPR sensory proteins-PERK (PEK/EIF2AK3), IRE1, and ATF6-is activated by ER stress.

Endoplasmic reticulum stress and the unfolded protein response in lung diseases: molecular pathways and therapeutic interventions

The Journal of Pathology, EarlyView.
Abstract Endoplasmic reticulum stress (ERS) occurs when the protein‐folding capacity of the endoplasmic reticulum (ER) is overwhelmed, triggering the unfolded protein response (UPR) to restore homeostasis. However, severe or persistent ERS can shift the UPR toward pro‐inflammatory, apoptotic, and fibrotic signaling, thereby exacerbating tissue injury ...

Endoproteolysis of the ER Stress Transducer ATF6 in the Presence of Functionally Inactive Presenilins

Neurobiology of Disease, 2001
Presenilin (PS) proteins facilitate endoproteolysis of selected type I transmembrane proteins such as the Alzheimer's disease (AD) associated β-Amyloid precursor protein (βAPP) and Notch.

Estrogens promote misfolded proinsulin degradation to protect insulin production and delay diabetes [PDF]

, 2018
Summary: Conjugated estrogens (CE) delay the onset of type 2 diabetes (T2D) in postmenopausal women, but the mechanism is unclear. In T2D, the endoplasmic reticulum (ER) fails to promote proinsulin folding and, in failing to do so, promotes ER stress and

Chrysin Mitigates Acetamiprid‐Induced Testicular Injury in Mice via Suppression of Endoplasmic Reticulum Stress and Inflammation

Environmental Toxicology, EarlyView.
ABSTRACT Acetamiprid (ACP) is a neonicotinoid pesticide that is extensively utilized for the management of insect populations, but its toxic effects on the male reproductive system have become a source of concern. Chrysin (CHR) is a natural flavone found in many plants and bee products, including honey and propolis.

ER stress‐related ATF6 upregulates CIP2A and contributes to poor prognosis of colon cancer

Molecular Oncology, 2018
Endoplasmic reticulum (ER) stress is an adaptive response to various stress conditions and plays emerging roles in cancer. Activating transcription factor 6 (ATF6), one of the three major ER stress transducers, has been shown to contribute to ...
