A Specific tRNA Half, 3'tiRNA‐GlyGCC, Regulates Hypoxic Pulmonary Artery Smooth Muscle Cell Proliferation via Myrf‐Mediated Endoplasmic Reticulum Stress

Cell Proliferation, EarlyView.
A schematic diagram illustrating how 3′tiRNA‐GlyGCC promotes the endoplasmic reticulum stress (ERS) and proliferation in hypoxic pulmonary artery smooth muscle cells (PASMCs) by inhibiting the expression of myelin regulatory factor (Myrf), ultimately leading to pulmonary hypertension (PH).

ER proteostasis meets mitochondrial function: contact sites as hubs of communication and therapeutic targets

The FEBS Journal, EarlyView.
Proteostasis ensures proper protein folding, modification, and degradation, while its impairment triggers ER stress. Chronic ER stress and maladaptive UPR via the CHOP–ERO1 axis remodel ERMCs, altering calcium signaling and mitochondrial metabolism.

The Endoplasmic Reticulum Stress Sensor Inositol-Requiring Enzyme 1α Augments Bacterial Killing through Sustained Oxidant Production

mBio, 2015
Bacterial infection can trigger cellular stress programs, such as the unfolded protein response (UPR), which occurs when misfolded proteins accumulate within the endoplasmic reticulum (ER).

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Unfolded protein response transducer IRE1-mediated signaling independent of XBP1 mRNA splicing is not required for growth and development of medaka fish

eLife, 2017
When activated by the accumulation of unfolded proteins in the endoplasmic reticulum, metazoan IRE1, the most evolutionarily conserved unfolded protein response (UPR) transducer, initiates unconventional splicing of XBP1 mRNA.

Biogenesis of TNF‐α‐insights into proteostasis and inflammation

The FEBS Journal, EarlyView.
TNF‐α biogenesis, trafficking, and signalling are tightly and reciprocally coupled to cellular proteostasis systems, including ER chaperones and endoplasmic reticulum‐associated degradation. This bidirectional crosstalk determines whether TNF‐α responses are adaptive or proteotoxic.

Iloperidone treatment mitigates the Juvenile Huntington's Disease phenotype possibly via Sigma‐1 Receptor Modulation

The FEBS Journal, EarlyView.
We investigated the potential of iloperidone as an activator of Sigma‐1 receptor (S1R) neuroprotective function in juvenile Huntington's disease (jHD). We tested iloperidone on cortical neurons differentiated from patient‐derived iPSCs, demonstrating that it acts as a S1R agonist, decreasing apoptosis, huntingtin aggregation, and oxidative stress ...

Ubiquitin and ubiquitin‐like modifications in the endoplasmic reticulum stress response

The FEBS Journal, EarlyView.
Endoplasmic reticulum (ER) stress activates various proteostasis control processes, including the unfolded protein response, ribosome‐associated quality control, and ER‐associated degradation. Ubiquitin and ubiquitin‐like modifications dynamically regulate these processes to determine cell fate, promoting adaptation or inducing cell death.

The unfolded protein sensor IRE1 is essential for homeostatic dendritic cell maturation

Nature Communications
Conventional type I dendritic cells (cDC1s) undergo homeostatic maturation upon apoptotic cell engulfment, hallmarked by the activation of the transcription factor LXRβ, which mediates cholesterol efflux and dampens interferon-stimulated gene expression.

IRE1-bZIP60 Pathway Is Required for Nicotiana attenuata Resistance to Fungal Pathogen Alternaria alternata

Frontiers in Plant Science, 2019
As an endoplasmic reticulum (ER) stress sensor, inositol-requiring enzyme 1 (IRE1) splices the bZIP60 mRNA, and produces an active bZIP60 transcription factor that regulates genes involved in the unfolded protein response (UPR) during ER stresses.
