Role of the Unfolded Protein Response in β Cell Compensation and Failure during Diabetes

Journal of Diabetes Research, 2014
Pancreatic β cell failure leads to diabetes development. During disease progression, β cells adapt their secretory capacity to compensate the elevated glycaemia and the peripheral insulin resistance.

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

Environmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

The Stress Rheostat: An Interplay Between the Unfolded Protein Response (UPR) and Autophagy in Neurodegeneration

Current Molecular Medicine, 2008
The unfolded protein response (UPR) is a conserved adaptive reaction that increases cell survival under conditions of endoplasmic reticulum (ER) stress. The UPR controls diverse processes such as protein folding, secretion, ER biogenesis, protein quality control and macroautophagy.

Comparative Analysis of Heat Exposure‐Induced Molecular Changes in Two Turtle Species with Contrasting Thermal Adaptations

Integrative Zoology, EarlyView.
Protein processing in the endoplasmic reticulum is highlighted in response to heat stress in Platysternon megacephalum. Under heat stress, the up‐regulation of genes such as CHOP in protein processing in the endoplasmic reticulum pathway, along with the suppression of energy and lipid metabolism and the up‐regulation of JARID2 expression, leads to ...

Systemic signaling contributes to the unfolded protein response of the plant endoplasmic reticulum

Nature Communications, 2018
The unfolded protein response (UPR) maintains cellular function under ER stress. While typically considered cell autonomous, here Lai et al. show that in Arabidopsis the UPR also has a systemic component triggered by intercellular movement of at least ...

Folding, misfolding, and regulation of intracellular traffic of G protein‐coupled receptors involved in the hypothalamic–pituitary–gonadal axis

Andrology, EarlyView.
Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.

Identification of novel components of the Unfolded Protein Response in Arabidopsis

Frontiers in Plant Science, 2016
Unfavorable environmental and developmental conditions may cause disturbances in protein folding in the endoplasmic reticulum (ER) that are recognized and counteracted by components of the Unfolded Protein Response (UPR) signaling pathways.

A quad‐cistronic fluorescent biosensor system for real‐time detection of subcellular Ca2+ signals

British Journal of Pharmacology, EarlyView.
Background and Purpose The calcium ion (Ca2+) is a versatile cellular messenger regulating a variety of biological processes. Compounds modulating subcellular Ca2+ signals hold substantial pharmacological potential. Advances in fluorescent biosensors have revolutionised Ca2+ imaging.

Differential regulation of translational stress responses by herpesvirus ubiquitin deconjugases

The FEBS Journal, EarlyView.
Translating viral mRNAs is challenging due to structural features that may slow translation or induce ribosome stalling. The viral ubiquitin deconjugases encoded by human pathogenic herpesviruses regulate the cellular response to ribosomal stress by inhibiting various branches of the Ribosomal Quality Control (RQC) and activating Ribosomal Stress ...
