T-cell internal antigen-1 (TIA-1) has roles in regulating alternative pre-mRNA splicing, mRNA translation, and stress granule (SG) formation in human cells. As an evolutionarily conserved response to environmental stress, SGs have been reported in various species. However, SG formation in chicken cells and the role of chicken TIA-1 (cTIA-1) in SG assembly has not been elucidated. In the present...

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...

Computational problems can be specified by logical statements interpreted in a computable model (a.k.a. claims). Semantic Games (SGs) of claims, a well-researched area, provide novel answers to crowdsourcing challenges yet with several limitations. Most notably that SGs provide a binary interaction mechanism that requires both participants to hold contradictory positions on the underlying claim...

UNLABELLED Stress granules (SGs) are dynamic accumulations of stalled preinitiation complexes and translational machinery that assemble under stressful conditions. Sodium selenite (Se) induces the assembly of noncanonical type II SGs that differ in morphology, composition, and mechanism of assembly from canonical SGs. Se inhibits translation initiation by altering the cap-binding activity of eu...

The Sgs-7 and Sgs-8 glue genes at 68C are divergently transcribed and are separated by 475 bp. Fusion genes with Adh or lacZ coding sequences were constructed, and the expression of these genes, with different amounts of upstream sequences present, was tested by a transient expression procedure and by germ line transformation. A cis-acting element for both genes is located asymmetrically in the...

Myosin Va (MyoVa) is a prime candidate for controlling actin-based organelle motion in neurons and neuroendocrine cells. Its function in secretory granule (SG) trafficking was investigated in enterochromaffin cells by wide-field and total internal reflection fluorescence microscopy. The distribution of endogenous MyoVa partially overlapped with SGs and microtubules. Impairing MyoVa function by ...

Sjögren's syndrome (SjS) is an autoimmune disease characterized by distraction of particularly salivary and lacrimal glands. The aim of the present study was to compare salivary gland scintigraphy (SGS) and salivary gland ultrasonography (SUS) in identifying salivary gland function in patients first diagnosed with SjS. We recruited 20 such patients with SjS (5 male, 15 female, aged from 35 to 6...

Large eddy simulation (LES) is regarded as one of the most promising numerical methods to predict unsteady turbulent flows at high Reynolds number. In LES the flow field is decomposed into grid and subgrid scales. The grid scale (GS) flow field is computed numerically using discrete filtered Navier-Stokes equation with a model for the subgrid scale (SGS) stress. Therefore, the reliability of th...

An essential constituent of the integrated stress response (ISR) is a reversible translational suppression. This mRNA silencing occurs in distinct cytoplasmic foci called stress granules (SGs), which transiently associate with processing bodies (PBs), typically serving as mRNA decay centers. How mRNAs are protected from degradation in these structures remains elusive. We identify that Zipcode-b...
