Lighting Up the Stressed ER [PDF]
Balancing the capacity for protein maturation with changes in protein flux through the endoplasmic reticulum (ER) is crucial for maintaining ER homeostasis. In this issue, Merksamer et al. (2008) exploit a redox-sensitive fluorescent protein to monitor the environment inside the ER of living yeast, illuminating how this organelle responds to different ...

Ltc1 is an ER-localized sterol transporter and a component of ER-mitochondria and ER-vacuole contacts. [PDF]
Organelle contact sites perform fundamental functions in cells, including lipid and ion homeostasis, membrane dynamics, and signaling. Using a forward proteomics approach in yeast, we identified new ER-mitochondria and ER-vacuole contacts specified by an

Rab7a modulates ER stress and ER morphology
The Endoplasmic Reticulum (ER) is a membranous organelle with diverse structural and functional domains. Peripheral ER includes interconnected tubules, and dense tubular arrays called "ER matrices" together with bona fide flat cisternae. Transitions between these states are regulated by membrane-associated proteins and cytosolic factors.

Ethanol Induced Disordering of Pancreatic Acinar Cell Endoplasmic Reticulum: An ER Stress/Defective Unfolded Protein Response Model. [PDF]
Background & aimsHeavy alcohol drinking is associated with pancreatitis, whereas moderate intake lowers the risk. Mice fed ethanol long term show no pancreas damage unless adaptive/protective responses mediating proteostasis are disrupted. Pancreatic

Stress management at the ER: Regulators of ER stress-induced apoptosis
The endoplasmic reticulum (ER) is an elaborate cellular organelle essential for cell function and survival. Conditions that interfere with ER function lead to the accumulation and aggregation of unfolded proteins which are detected by ER transmembrane receptors that initiate the unfolded protein response (UPR) to restore normal ER function.

Estrogens promote misfolded proinsulin degradation to protect insulin production and delay diabetes [PDF]
Summary: Conjugated estrogens (CE) delay the onset of type 2 diabetes (T2D) in postmenopausal women, but the mechanism is unclear. In T2D, the endoplasmic reticulum (ER) fails to promote proinsulin folding and, in failing to do so, promotes ER stress and

ER stress modulates cellular metabolism [PDF]
Changes in metabolic processes play a critical role in the survival or death of cells subjected to various stresses. In the present study, we have investigated the effects of ER (endoplasmic reticulum) stress on cellular metabolism. A major difficulty in studying metabolic responses to ER stress is that ER stress normally leads to apoptosis and ...

Reciprocal regulation between ER stress and autophagy in renal tubular fibrosis and apoptosis
Both endoplasmic reticulum (ER) stress and autophagy have been implicated in chronic kidney injury and renal fibrosis. However, the relationship and regulatory mechanisms between ER stress and autophagy under this condition remain largely unknown.

Interplay between endoplasmic reticulum (ER) stress and autophagy induces mutant p53H273 degradation [PDF]
The unfolded protein response (UPR) is an adaptive response to intrinsic and external stressors, and it is mainly activated by the accumulation of misfolded proteins at the endoplasmic reticulum (ER) lumen producing ER stress.

Lipid nanoparticles as a tool to dissect dendritic cell maturation pathways
Summary: Depending on how antigens are being decoded by dendritic cells (DCs), their acquisition will induce a homeostatic or immunogenic maturation program.
