Yeast Gcn2 retains activity following humanization of its auto‐phosphorylation region

FEBS Open Bio, EarlyView.
Using Saccharomyces cerevisiae as a model to study Gcn2 activation and regulation is limited by the lack of antibodies detecting phosphorylated Gcn2. To overcome this, we engineered Gcn2‐HsC, a yeast Gcn2 variant recognizable by commercial anti‐human phospho‐GCN2 antibodies.

Mechanistic insights into post-translational modifications in hepatic fibrosis: pathogenic roles and therapeutic potentials

Journal of Translational Medicine
Hepatic fibrosis, a critical progression in liver disease, has been widely studied. While the activation of stellate cells and the accumulation of extracellular matrix components are recognized as key mechanisms, additional research is necessary to ...

Microglial activation in spaceflight and microgravity: potential risk of cognitive dysfunction and poor neural health

Frontiers in Cellular Neuroscience
Due to the increased crewed spaceflights in recent years, it is vital to understand how the space environment affects human health. A lack of gravitational force is known to risk multiple physiological functions of astronauts, particularly damage to the ...

Lysosome blockade induces divergent metabolic programs in macrophages and tumours for cancer immunotherapy

Journal of Experimental & Clinical Cancer Research, 2023
Background Platinum-drugs based chemotherapy in clinic increases the potency of tumor cells to produce M2 macrophages, thus leading to poor anti-metastatic activity and immunosuppression.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Identification of (20R)‐protopanaxadiol from Panax ginseng as a novel anti‐SARS‐CoV‐2 compound

FEBS Open Bio, EarlyView.
We established a noninfectious BAC‐based SARS‐CoV‐2 replicon that enables antiviral screening under BSL‐2 conditions. Using this platform, we screened 373 food‐derived compounds and identified (20R)‐protopanaxadiol from Panax ginseng as a novel inhibitor of SARS‐CoV‐2 RNA replication, highlighting the value of safe replicon systems for antiviral ...

Protocol for quantifying miRNA trafficking across the endosomal membrane

FEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Type I interferons modulate autophagy to shape gemcitabine response in pancreatic cancer cells

FEBS Open Bio, EarlyView.
Type I interferons differentially modulate autophagy and the response of pancreatic cancer cells to gemcitabine. IFNα2b stimulates autophagic flux and protects cells from gemcitabine‐induced cell death, contributing to chemoresistance. In contrast, IFNβ1a inhibits autophagosome formation and enhances gemcitabine‐induced cell death, resulting in ...

Effect of paternal exposure to glyphosate and microcystin-LR on zebrafish (Danio rerio) fathers and progeny: An integrated investigation based on behavioral, histopathological, biochemical, and transcriptomic analysis

Ecotoxicology and Environmental Safety
The coexistence of glyphosate (GLY) and microcystin-LR (MC-LR) in the environment has become a problem that cannot be ignored. However, the combined toxic effects of these compounds on aquatic organisms remain underexplored. The purpose of this study was
