Recent Advances in Virus–Host Interactions, Antiviral Bioactive Compounds, and Breeding for Disease Resistance of Porcine Epidemic Diarrhea Virus

open access: yesAnimal Research and One Health, EarlyView.
Basic research on the PEDV infection cycle and virus–host interactions advances the development of anti‐PEDV drugs and disease‐resistant breeding and helps strengthen disease prevention and control while reducing economic losses in the swine industry.

The phosphorylation of carboxyl-terminal eIF2α by SPA kinases contributes to enhanced translation efficiency during photomorphogenesis

open access: yesNature Communications
Light triggers an enhancement of global translation during photomorphogenesis in Arabidopsis, but little is known about the underlying mechanisms. The phosphorylation of the α-subunit of eukaryotic initiation factor 2 (eIF2α) at a conserved serine ...

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

open access: yesJournal 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 ...

Phosphorylation of the Translation Initiation Factor eIF2α Increases BACE1 Levels and Promotes Amyloidogenesis

open access: yes, 2008
Summaryβ-site APP cleaving enzyme-1 (BACE1), the rate-limiting enzyme for β-amyloid (Aβ) production, is elevated in Alzheimer's disease (AD). Here, we show that energy deprivation induces phosphorylation of the translation initiation factor eIF2α (eIF2α ...

Toxicity Differences Between Microplastics and Nanoplastics in Organs: From Molecular Mechanisms to Potential Therapeutic Strategies

open access: yesMed Research, EarlyView.
This review systematically compares the size‐dependent toxicity of microplastics and nanoplastics in the intestine, liver, kidney, lung, and brain. Particle size determines bioavailability, barrier penetration, and injury mechanisms. Because of their small size and high surface reactivity, NPs readily cross the intestinal epithelium and blood–brain ...

Butein Attenuates Cardiac Hypertrophy by Restoring Redox–Mitochondrial Homeostasis Through Nrf2–Sirt3 Signaling

open access: yesPhytotherapy Research, EarlyView.
Butein attenuates pathological cardiac hypertrophy by activating Nrf2–Sirt3 signaling, restoring mitochondrial function and redox homeostasis. ABSTRACT Butein (3,4,2′,4′‐tetrahydroxychalcone) is a bioactive chalcone with antioxidant, anti‐inflammatory, and cytoprotective properties.

Deletion of the eIF2α Kinase GCN2 fails to rescue the memory decline associated with Alzheimer's disease.

open access: yesPLoS ONE, 2013
Emerging evidence suggests that dysregulated translation through phosphorylation of eukaryotic initiation factor-2α (eIF2α) may contribute to Alzheimer's disease (AD) and related memory impairments. However, the underlying mechanisms remain unclear. Here,

Phosphorylation of initiation factor eIF2 in response to stress conditions is mediated by acidic ribosomal P1/P2 proteins in Saccharomyces cerevisiae. [PDF]

open access: yesPLoS ONE, 2013
Eukaryotic cells contain an unusually large cytoplasmic pool of P1/P2 phosphoproteins, which form the highly flexible 60S subunit stalk that is required to interact with and activate soluble translation factors.

Phosphorylation of eukaryotic initiation factor-2α (eIF2α) is associated with neuronal degeneration in Alzheimer's disease

open access: yes, 2002
Inhibition of protein translation is a mode of inducing neuronal apoptosis and neurodegeneration in Alzheimer's disease (AD). Phosphorylation of eukaryotic initiation factor-2α (eIF2α) terminates global protein translation and induces apoptosis.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

open access: yesInsect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.
