P-body and Stress Granule Quantification in Caenorhabditis elegans

Bio-Protocol, 2017
Eukaryotic cells contain various types of cytoplasmic, non-membrane bound ribonucleoprotein (RNP) granules that consist of non-translating mRNAs and a versatile set of associated proteins. One prominent type of RNP granules is Processing bodies (P bodies)

Induction of Stress Granule Assembly is Essential for the Orchestration of DNA Damage Response [PDF]

, 2008
DNA damage provokes several responses including DNA repair, cell cycle regulation and apoptosis that collectively represent the DNA damage response (DDR).

On mesogranulation, network formation and supergranulation [PDF]

, 2000
We present arguments which show that in all likelihood mesogranulation is not a true scale of solar convection but the combination of the effects of both highly energetic granules, which give birth to strong positive divergences (SPDs) among which we ...

A switch for stress granule assembly [PDF]

Journal of Cell Biology, 2016
![Figure][1] Cells overexpressing USP10 (green) fail to form stress granules (magenta) when translation initiation is inhibited. [Kedersha et al.][2] describe how phosphorylation and the competition between mutually exclusive binding partners regulate G3BP’s ability to mediate ...

Amyloidogenic Peptide Fragments Designed From Bacterial Collagen‐like Proteins Form Hydrogel

Advanced Functional Materials, EarlyView.
This study identified amyloidogenic sequence motifs in bacterial collagen‐like proteins and exploited these to design peptides that self‐assemble into β‐sheet fibers and form hydrogels. One hydrogel supported healthy fibroblast growth, showing promise for biocompatible materials. Our work demonstrates that bacterial sequences can be harnessed to create

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

Advanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

Establishing a Model Precursor System: Over a Decade of Research on Carbon Dots from the Citric Acid‐Urea System

Advanced Functional Materials, EarlyView.
The citric acid/urea (CA‐Urea) precursor system offers a versatile, scalable route to carbon dots with tunable luminescence and multifunctionality. Mechanistic insights into precursor chemistry and reaction parameters have enabled doping, surface modification, and hybridization strategies, yielding CDs for luminescent devices, sensing, catalysis ...

Tia1 dependent regulation of mRNA subcellular location and translation controls p53 expression in B cells

Nature Communications, 2017
Sequestering mRNA in cytoplasmic stress granules is a mechanism for translational repression. Here the authors find that p53 mRNA, present in stress granules in activated B lymphocytes, is released upon DNA damage and is translated in a CAP-independent ...

Tissue‐Stimulator Platform for Electrically Stimulating Pancreatic β‐Cells for Long‐Term Functional Regulation

Advanced Functional Materials, EarlyView.
We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

Ar s enite treatment induces Hsp90 aggregates distinct from conventional stress granules in fission yeast

Microbial Cell
Various stress conditions, such as heat stress (HS) and oxidative stress, can cause biomolecular condensates represented by stress granules (SGs) via liquid-liquid phase separation.
