Stress granule dynamics
WebStress granules formation is connected to several diseases, including neurodegeneration. The formation of SGs is considered a pro-survival strategy in neurons to ease out the intermittent stresses. However, persistent stress and mutation in RNA binding proteins could increase SGs in the neuron that could be toxic leading to pathology. WebJan 1, 2024 · Both SGs and PBs are dynamic structures that constantly exchange mRNAs with the cytosol, polysomes and other RNA granules [ 13, 15 ]. Drugs that stabilize polysomes (e.g. cycloheximide (CHX), emetine) and thus disrupt this equilibrium cause the disassembly of SGs and PBs [ 8, 52 ].

WebApr 30, 2024 · Stress granule (SG) formation is frequently accompanied by ubiquitin proteasome system (UPS) impairment and ubiquitylated protein accumulation. SGs, ubiquitin, and UPS components co-localize, but the relationship between the ubiquitin pathway and SGs has not been systematically characterized. WebJun 25, 2024 · In response to many types of stress, eukaryotic cells initiate an adaptive and reversible response that includes down-regulation of key cellular activities along with sequestration of cytoplasmic mRNAs into structures called stress granules.
