Stress granules
Cell growth and proliferation are fundamental processes in living organisms and are dynamically controlled by environmental cues. TOR complex 1 (TORC1) is a central protein kinase involved in the regulation of cell growth in response to a wide variety of cellular states and is the target of the immunosuppressant and anticancer drug rapamycin. In the budding yeast Saccharomyces cerevisiae, TORC1...
متن کاملStress granules
What are stress granules? Stress granules are non-membranous cytoplasmic foci ranging in size from 0.1 to 2.0 μm, composed of non-translating messenger ribonucleoproteins (mRNPs) that rapidly aggregate in cells exposed to adverse environmental conditions. Their assembly is triggered by a variety of environmental stresses including heat shock, oxidative stress, hyperosmolarity, viral infection, ...
متن کاملUVC-Induced Stress Granules in Mammalian Cells
Stress granules (SGs) are well characterized cytoplasmic RNA bodies that form under various stress conditions. We have observed that exposure of mammalian cells in culture to low doses of UVC induces the formation of discrete cytoplasmic RNA granules that were detected by immunofluorescence staining using antibodies to RNA-binding proteins. UVC-induced cytoplasmic granules are not Processing Bo...
متن کاملYeast processing bodies and stress granules: self-assembly ribonucleoprotein particles
Processing bodies (PBs) and stress granules (SGs) are two highly conserved cytoplasmic ribonucleoprotein foci that contain translationally repressed mRNAs together with proteins from the mRNA metabolism. Interestingly, they also share some common features with other granules, including the prokaryotic inclusion bodies. Although the function of PBs and SGs remains elusive, major advances have be...
متن کاملStress-specific differences in assembly and composition of stress granules and related foci.
Cells have developed different mechanisms to respond to stress, including the formation of cytoplasmic foci known as stress granules (SGs). SGs are dynamic and formed as a result of stress-induced inhibition of translation. Despite enormous interest in SGs due to their contribution to the pathogenesis of several human diseases, many aspects of SG formation are poorly understood. SGs induced by ...
