, 2020 The capacity of cells to organize complex biochemical reactions in intracellular space is a fundamental organizational principle of life. Key to this organization is the compartmentalization of the cytoplasm into distinct organelles, which is frequently achieved through intracellular membranes.

Sequestration of highly expressed mRNAs in cytoplasmic granules, P-bodies, and stress granules enhances cell viability. [PDF]
PLoS Genetics, 2012 Transcriptome analyses indicate that a core 10%-15% of the yeast genome is modulated by a variety of different stresses. However, not all the induced genes undergo translation, and null mutants of many induced genes do not show elevated sensitivity to ...

Cell Reports, 2018 Summary: Stress granules are non-membranous structures that transiently form in the cytoplasm during cellular stress, where they promote translational repression of non-essential RNAs and modulate cell signaling by sequestering key signal transduction ...

Stress Granules and Virus Replication [PDF]
Future Virology, 2011 Viruses are dependent on the cellular translation machinery for protein synthesis. Part of the innate immune response to infection is activation of the stress kinase PKR which phosphorylates the alpha subunit of the initiation factor eIF2. This results in inhibition of translation and is intended to block virus replication.

Shigella flexnerimodulates stress granule composition and inhibits stress granule aggregation [PDF]
Cellular Microbiology, 2016 Invasion and multiplication of the facultative, cytosolic, enteropathogen Shigella flexneri within the colonic epithelial lining leads to an acute inflammatory response, fever and diarrhea. During the inflammatory process, infected cells are subjected to numerous stresses including heat, oxidative stress and genotoxic stress.

The Stress Granule Transcriptome Reveals Principles of mRNA Accumulation in Stress Granules [PDF]
Molecular Cell, 2017 Stress granules are mRNA-protein assemblies formed from nontranslating mRNAs. Stress granules are important in the stress response and may contribute to some degenerative diseases. Here, we describe the stress granule transcriptome of yeast and mammalian cells through RNA-sequencing (RNA-seq) analysis of purified stress granule cores and single ...

Frontiers in Molecular Biosciences, 2022 Stress granules are non-membrane bound RNA-protein granules essential for survival during acute cellular stress. TIA-1 is a key protein in the formation of stress granules that undergoes liquid-liquid phase separation by association with specific RNAs ...

Stress granule transcription [PDF]
Science, 2018 Molecular Biology When translation initiation is stalled under stress, nontranslating messenger ribonucleoproteins form insoluble assemblies called stress granules (SGs) in the cytosol. Namkoong et al. sequenced all transcripts from purified SGs. They found that although translation of most transcripts is inhibited, only a subset of transcripts form ...

Stress‐induced mRNP granules: Form and function of processing bodies and stress granules [PDF]
WIREs RNA, 2019 In response to stress, cells must quickly reprogram gene expression to adapt and survive. This is achieved in part by altering levels of mRNAs and their translation into proteins. Recently, the formation of two stress‐induced messenger ribonucleoprotein (mRNP) assemblies named stress granules and processing bodies has been postulated to directly impact

Development of a novel light-up probe for detection of G-quadruplexes in stress granules
Scientific Reports, 2022 G-quadruplexes (G4s) regulate various biological processes in cells. However, cellular imaging of dynamically forming G4s in biomolecular condensates using small molecules has been poorly investigated. Herein, we present a fluorescent light-up probe with
