Lysosome Evanescence Mediates Autophagic Flux Impairment in Glucose Imbalanced Environments

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Schwann cells (SCs) support axonal function and promote nerve regeneration. This study investigated how various glucose concentrations influence SC viability, oxidative stress, and autophagy, which contribute to diabetic neuropathy. RSC96 SCs were cultured under five glucose conditions (0, 2.5, 5.5, 50, or 100 mM) for 24, 48, and 72 h.

Betacoronaviruses Differentially Activate the Integrated Stress Response to Optimize Viral Replication in Lung-Derived Cell Lines

Viruses
The betacoronavirus genus contains five of the seven human coronaviruses, making it a particularly critical area of research to prepare for future viral emergence. We utilized three human betacoronaviruses, one from each subgenus—HCoV-OC43 (embecovirus),

Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to

ER stress-induced eIF2-alpha phosphorylation underlies sensitivity of striatal neurons to pathogenic huntingtin.

PLoS ONE, 2014
A hallmark of Huntington's disease is the pronounced sensitivity of striatal neurons to polyglutamine-expanded huntingtin expression. Here we show that cultured striatal cells and murine brain striatum have remarkably low levels of phosphorylation of ...

Universal and Lineage‐Specific Patterns in the Distribution of ECOD Domain Homology Groups Across Superkingdoms

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Proteins are built from modular domains that serve as fundamental units of structure and evolution. While individual domains have been extensively cataloged, their collective distribution across the lineages of life has remained poorly resolved.

Deficiency of heme-regulated eIF2α kinase decreases hepcidin expression and splenic iron in HFE−/− mice

Haematologica, 2008
Heme-regulated eIF2α kinase (HRI) is essential for regulating globin translation in iron deficiency and in β-thalassemia. We investigated the role of heme-regulated eIF2α kinase in hemoglobin and red blood cell production as well as in iron homeostasis ...

Twenty‐Five Years of the Environmental Stress Response and the Enduring Power of Yeast in Stress Biology

Yeast, EarlyView.
ABSTRACT All organisms must be able to sense and respond to adverse environments, especially those that threaten cellular integrity. The age of genomics clarified the breadth and specificity of cellular stress responses, including in free‐living microbes directly exposed to a changing environment.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

Insect 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.

Inhibition of eIF2α dephosphorylation inhibits ErbB2-induced deregulation of mammary acinar morphogenesis

BMC Cell Biology, 2009
Background The ErbB2/Her2/Neu receptor tyrosine kinase is amplified in ~30% of human breast cancers. Phosphorylation of the translation initiation factor, eIF2α inhibits global protein synthesis and activates a stress signaling and growth suppressive ...
