Shigella flexnerimodulates stress granule composition and inhibits stress granule aggregation [PDF]
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 MRN complex is transcriptionally regulated by MYCN during neural cell proliferation to control replication stress [PDF]
The MRE11/RAD50/NBS1 (MRN) complex is a major sensor of DNA double strand breaks, whose role in controlling faithful DNA replication and preventing replication stress is also emerging. Inactivation of the MRN complex invariably leads to developmental and/

Summary: Low-complexity “prion-like” domains in key RNA-binding proteins (RBPs) mediate the reversible assembly of RNA granules. Individual RBPs harboring these domains have been linked to specific neurodegenerative diseases.

Aspergillus oryzae AoSO is a novel component of stress granules upon heat stress in filamentous fungi. [PDF]
Stress granules are a type of cytoplasmic messenger ribonucleoprotein (mRNP) granule formed in response to the inhibition of translation initiation, which typically occurs when cells are exposed to stress.

TIA1 Mutations in Amyotrophic Lateral Sclerosis and Frontotemporal Dementia Promote Phase Separation and Alter Stress Granule Dynamics. [PDF]
Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are age-related neurodegenerative disorders with shared genetic etiologies and overlapping clinical and pathological features. Here we studied a novel ALS/FTD family and identified the

Stress granule transcription [PDF]
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 ...

Background-deflection Brillouin microscopy reveals altered biomechanics of intracellular stress granules by ALS protein FUS [PDF]
Altered cellular biomechanics have been implicated as key photogenic triggers in age-related diseases. An aberrant liquid-to-solid phase transition, observed in in vitro reconstituted droplets of FUS protein, has been recently proposed as a possible ...

Stress‐induced mRNP granules: Form and function of processing bodies and stress granules [PDF]
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

Summary: How cells adapt to varying environmental conditions is largely unknown. Here, we show that, in budding yeast, the RNA-binding and stress granule protein Pub1 has an intrinsic property to form condensates upon starvation or heat stress and that ...

Infectious Bronchitis Virus Regulates Cellular Stress Granule Signaling
Viruses must hijack cellular translation machinery to express viral genes. In many cases, this is impeded by cellular stress responses. These stress responses result in the global inhibition of translation and the storage of stalled mRNAs, into RNA ...
