Viral modulation of stress granules
Virus Research, 2012 Following viral infection, the host responds by mounting a robust anti-viral response with the aim of creating an unfavorable environment for viral replication. As a countermeasure, viruses have elaborated mechanisms to subvert the host response in order to maintain viral protein synthesis and production.

Stress granules dynamics: benefits in cancer
BMB Reports, 2022 Stress granules (SGs) are stress-induced subcellular compartments, which carry out a particular function to cope with stress. These granules protect cells from stress-related damage and cell death through dynamic sequestration of numerous ribonucleoproteins (RNPs) and signaling proteins, thereby promoting cell survival under both physiological and ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Who Regulates Whom? An Overview of RNA Granules and Viral Infections
Viruses, 2016 After viral infection, host cells respond by mounting an anti-viral stress response in order to create a hostile atmosphere for viral replication, leading to the shut-off of mRNA translation (protein synthesis) and the assembly of RNA granules.

Dance with the Devil: Stress Granules and Signaling in Antiviral Responses
Viruses, 2020 Cells have evolved highly specialized sentinels that detect viral infection and elicit an antiviral response. Among these, the stress-sensing protein kinase R, which is activated by double-stranded RNA, mediates suppression of the host translation ...

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

RNA self-assembly contributes to stress granule formation and defining the stress granule transcriptome [PDF]
Proceedings of the National Academy of Sciences, 2018 Significance Stress granules, which are ubiquitous, non–membrane-bound assemblies of protein and RNA, form when translation initiation is inhibited, contribute to the regulation of gene expression, and are implicated in the pathologies of cancer and neurodegenerative disease. Understanding the mechanisms of stress

Stress granules regulate paraspeckles: RNP granule continuum at work [PDF]
Cell Stress, 2019 Eukaryotic cells contain several types of RNA-protein membraneless macro-complexes - ribonucleoprotein (RNP) granules that form by liquid-liquid phase separation. These structures represent biochemical microreactors for a variety of cellular processes and also act as highly accurate sensors of changes in the cellular environment.

FEBS Letters, EarlyView.This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

P Bodies, Stress Granules, and Viral Life Cycles [PDF]
, 2008 Eukaryotic mRNAs are in a dynamic equilibrium between different subcellular locations. Translating mRNAs can be found in polysomes, mRNAs stalled in translation initiation accumulate in stress granules and mRNAs targeted for degradation or translation ...
