Angiogenin-Cleaved tRNA Halves Interact with Cytochrome c, Protecting Cells from Apoptosis during Osmotic Stress

M Saikia, R Jobava, M Parisien, A Putnam… - … and cellular biology, 2014 - Taylor & Francis
Adaptation to changes in extracellular tonicity is essential for cell survival. However, severe
or chronic hyperosmotic stress induces apoptosis, which involves cytochrome c (Cyt c) …

[PDF][PDF] A unique ISR program determines cellular responses to chronic stress

BJ Guan, V van Hoef, R Jobava, O Elroy-Stein… - Molecular cell, 2017 - cell.com
The integrated stress response (ISR) is a homeostatic mechanism induced by endoplasmic
reticulum (ER) stress. In acute/transient ER stress, decreased global protein synthesis and …

[HTML][HTML] Adaptation to chronic ER stress enforces pancreatic β-cell plasticity

…, L Gao, S Bracey, J Wu, CA Mbow, R Jobava… - Nature …, 2022 - nature.com
Pancreatic β-cells are prone to endoplasmic reticulum (ER) stress due to their role in insulin
secretion. They require sustainable and efficient adaptive stress responses to cope with this …

[PDF][PDF] DAZL regulates germ cell survival through a network of PolyA-proximal mRNA interactions

…, MM Hannigan, SM Weyn-Vanhentenryck, R Jobava… - Cell reports, 2018 - cell.com
The RNA binding protein DAZL is essential for gametogenesis, but its direct in vivo functions,
RNA targets, and the molecular basis for germ cell loss in Dazl-null mice are unknown. …

[HTML][HTML] Regulation of interferon-stimulated gene BST2 by a lncRNA transcribed from a shared bidirectional promoter

…, E Zebrowski, L Kostadinova, R Jobava… - Frontiers in …, 2015 - frontiersin.org
Recent genome-wide studies have revealed the presence of thousands of long non-protein-coding
RNAs (lncRNAs), some of which may play critical roles in the cell. We have …

[PDF][PDF] The influence of speed of approach and humidity on the intensity of ESD

S Frei, M Senghaas, R Jobava… - Proc. 13th Int. Zurich …, 1999 - bs.etit.tu-dortmund.de
ESD may be a serious threat to electronic devices and systems. The intensity of ESD can
vary strongly in spite of constant charge voltage. The bad reproducibility of ESD is notorious. …

PACT-mediated PKR activation acts as a hyperosmotic stress intensity sensor weakening osmoadaptation and enhancing inflammation

…, BJ Guan, Z Gao, XH Gao, J Wu, R Jobava… - Elife, 2020 - elifesciences.org
… We have shown that protein kinase R (PKR) promotes the nuclear localization of Serine-536
phosphorylated NF-kB family member p65, which leads to an increase in inflammatory …

Computer simulation of ESD from voluminous objects compared to transient fields of humans

R Jobava, D Pommerenke… - IEEE Transactions …, 2000 - ieeexplore.ieee.org
Computer simulation of electrostatic discharge (ESD) for simplified objects is described and
compared to measured transient fields of human/metal ESD. The simulation algorithm uses …

[PDF][PDF] Stress-induced perturbations in intracellular amino acids reprogram mRNA translation in osmoadaptation independently of the ISR

D Krokowski, R Jobava, KJ Szkop, CW Chen, X Fu… - Cell reports, 2022 - cell.com
The integrated stress response (ISR) plays a pivotal role in adaptation of translation
machinery to cellular stress. Here, we demonstrate an ISR-independent osmoadaptation …

[PDF][PDF] GADD34 function in protein trafficking promotes adaptation to hyperosmotic stress in human corneal cells

…, BJ Guan, J Wu, Y Zheng, PP Pattabiraman, R Jobava… - Cell reports, 2017 - cell.com
GADD34, a stress-induced regulatory subunit of the phosphatase PP1, is known to function
in hyperosmotic stress through its well-known role in the integrated stress response (ISR) …
