Effect of hypoxia, glutamine and glucose deprivation on the expression of mRNA of the retinoblastoma binding proteins in glioma cells

Біологічні студії, 2011
Hypoxia and ischemia, as well as endoplasmic reticulum stress, are principal factors which are necessary for tumor neovascularization and growth. We have studied the effect of blocking the endoplasmic reticulum – nuclei-1, the main signaling enzyme of ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Calcium bridges built by mitochondria-associated endoplasmic reticulum membranes: potential targets for neural repair in neurological diseases

Neural Regeneration Research
The exchange of information and materials between organelles plays a crucial role in regulating cellular physiological functions and metabolic levels. Mitochondria-associated endoplasmic reticulum membranes serve as physical contact channels between the ...

Endoplasmic reticulum–mitochondria interplay in chronic pain: The calcium connection

Molecular Pain, 2020
Chronic pain is a debilitating condition that affects roughly a third to a half of the world’s population. Despite its substantial effect on society, treatment for chronic pain is modest, at best, notwithstanding its side effects.

RBM10 Regulates Embryonic Trophoblast Injury via Endoplasmic Reticulum Stress

Clinical and Experimental Obstetrics & Gynecology, 2022
Background: Previous studies shown that RNA binding motif proteins (RBM) participate in regulating various physiological processes such as cell autophagy, proliferation, and apoptosis, and are abnormally highly expressed in placental trophoblast cells ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Stress Management: How the Endoplasmic Reticulum Mitigates Protein Misfolding and Oxidative Stress by the Dual Role of Glutathione Peroxidase 8

Biomolecules
The endoplasmic reticulum mediates essential processes such as protein folding, transport, and post-translational modifications. Disruptions in endoplasmic reticulum function can lead to the accumulation of unfolded or misfolded proteins, initiating ...

Endoplasmic reticulum stress-induced apoptosis in the penumbra aggravates secondary damage in rats with traumatic brain injury

Neural Regeneration Research, 2016
Neuronal apoptosis is mediated by intrinsic and extrinsic signaling pathways such as the membrane-mediated, mitochondrial, and endoplasmic reticulum stress pathways.

Sirtuin1 protects endothelial Caveolin-1 expression and preserves endothelial function via suppressing miR-204 and endoplasmic reticulum stress. [PDF]

, 2017
Sirtuin1 (Sirt1) is a class III histone deacetylase that regulates a variety of physiological processes, including endothelial function. Caveolin1 (Cav1) is also an important determinant of endothelial function. We asked if Sirt1 governs endothelial Cav1
