Mast cell clones: a model for the analysis of cellular maturation. [PDF]
Cloned mouse mast cells resemble, by ultrastructure, immature mast cells observed in vivo. These mast cell clones can be grown in the absence of any other cells, facilitating direct investigations of their biochemistry and function.

Stress granules are cytoplasmic foci that directly respond to the protein synthesis status of the cell. Various environmental insults, such as oxidative stress or extreme heat, block protein synthesis; consequently, mRNA will stall in translation, and ...

Cellular bases of the RNA metabolism dysfunction in motor neurons of a murine model of spinal muscular atrophy: Role of Cajal bodies and the nucleolus [PDF]
Spinal muscular atrophy (SMA) is caused by a homozygous deletion or mutation in the survival motor neuron 1 (SMN1) gene that leads to reduced levels of SMN protein resulting in degeneration of motor neurons (MNs).

Stress granules are non-membranous cytoplasmic foci induced by various stress conditions. It is a protective strategy used by cells to suppress overall translation during stress. In cancer cells, it was thought that the formation of stress granules could

ALS mutant FUS proteins are recruited into stress granules in induced pluripotent stem cells- derived motoneurons [PDF]
Patient-derived induced Pluripotent Stem Cells (iPSCs) provide an opportunity to study human diseases mainly in those cases where no suitable model systems are available.

Phase transitioned nuclear Oskar promotes cell division of Drosophila primordial germ cells
Germ granules are non-membranous ribonucleoprotein granules deemed the hubs for post-transcriptional gene regulation and functionally linked to germ cell fate across species.

The 5' → 3' exoribonuclease XRN1/Pacman and its functions in cellular processes and development [PDF]
XRN1 is a 5' → 3' processive exoribonuclease that degrades mRNAs after they have been decapped. It is highly conserved in all eukaryotes, including homologs in Drosophila melanogaster (Pacman), Caenorhabditis elegans (XRN1), and Saccharomyces cerevisiae (

Formation of Antiviral Cytoplasmic Granules during Orthopoxvirus Infection [PDF]
ABSTRACT Vaccinia virus (VV) mutants lacking the double-stranded RNA (dsRNA)-binding E3L protein (Δ E3L mutant VV) show restricted replication in most cell types, as dsRNA produced by VV activates protein kinase R (PKR), leading to eIF2α phosphorylation and impaired translation initiation.

Malonate induces the assembly of cytoplasmic stress granules [PDF]
Malonate, a classic inhibitor of respiratory electron transport chain, induces mitochondrial stress. Stress granules (SGs) are a kind of dynamic foci structure during stress. The study on the connection of mitochondrial stress and SG assembly is still limited.

Cytoplasmic protein granules organize kinase-mediated RAS signaling
Understanding how cells spatially organize signaling events is important in normal biology and pathological conditions such as cancer. Here, we uncover a membraneless, protein granule-based subcellular structure that can organize receptor tyrosine kinase
