Lysosome‐Featured Cell Aggregate‐Released Extracellular Vesicles Regulate Iron Homeostasis and Alleviate Post‐Irradiation Endothelial Ferroptosis for Mandibular Regeneration

Advanced Science, EarlyView.
Lysosomal redistribution occurs via extracellular vesicles in multi‐stem cell aggregates and controls iron homeostasis for safeguarding cell aggregation. These cell aggregate‐released extracellular vesicles (CA‐EVs) rescue lysosomal impairments and exert anti‐ferroptosis effects in recipient irradiated endothelial cells.

Ultrastructural localization of adenosine triphosphatase activity in lymphocytes activated in vitro by phytohaemagglutinin [PDF]

, 1982
The ultrastructural localization of Ca 2+, Mg2+ -activated ATPase was studied in phytohaemagglutinin activated lymphocytes and in normal unstimulated lymphocytes. Cells, fixed in paraformaldehyde-glutaraldehyde, were incubated in a medium containing 3 mM

Exploring Immediate Photon Effects From 635 nm Light on Mitochondrial Bioenergetics

Journal of Biophotonics, EarlyView.
The investigation of in vitro impacts of 635 nm laser irradiation in mitochondrial bioenergetics demonstrated that red light induces transient and localized effects, highlighting the complexities of cellular and mitochondrial photostimulation mechanisms. ABSTRACT Visible light primarily targets mitochondria at the cellular level, but photon interaction

Mitochondrial dynamics in autoimmune diseases

Rheumatology &Autoimmunity, EarlyView.
Roles of mitochondrial dynamic imbalance in autoimmune diseases. The imbalance of mitochondrial fusion and fission is involved in the occurrence and development of autoimmune diseases, including systemic lupus erythematosus, Sjogren's syndrome, rheumatoid arthritis, multiple sclerosis, myasthenia gravis, type 1 diabetes, psoriasis, and autoimmune ...

Analysis of the Movement of Chlamydomonas Flagella: The Function of the Radial-spoke System Is Revealed by Comparison of Wild-type and Mutant Flagella [PDF]

, 1982
The mutation uni-1 gives rise to uniflagellate Chlamydomonas cells which rotate around a fixed point in the microscope field, so that the flagellar bending pattern can be photographed easily .

Plasma membrane Ca2+-ATPases can shape the pattern of Ca2+ transients induced by store-operated Ca2+ entry [PDF]

, 2015
Calcium (Ca2+) is a critical cofactor and signaling mediator in cells, and the concentration of cytosolic Ca2+ is regulated by multiple proteins, including the plasma membrane Ca2+-ATPases (adenosine triphosphatases) (PMCAs), which use ATP to transport ...

Adenosine Triphosphatase Activity of the Vascular System.

Experimental Biology and Medicine, 1952
SummaryThe AT Pase activity of the vascular system of the dog has been studied, lit has been shown that the enzyme content of -the different arteries enjoys wide variation. The venous system does not contain the enzyme. ATPase activity of the aorta of the rat was not influenced by age or captivity.

Epigenetic control of cell identities from epiblast to gastrulation

The FEBS Journal, EarlyView.
In this review, we present and contextualize current knowledge about the roles of epigenetic modifiers during the development of mouse epiblast to gastrulation stage. The epigenetic regulation of enhancer and promoter elements by DNA methylation, histone modifications, and chromatin accessibility in concert with lineage‐specific transcription factors ...

Omics approaches to identify potential biomarkers of inflammatory diseases in the focal adhesion complex [PDF]

, 2017
Inflammatory diseases such as inflammatory bowel disease require recurrent invasive tests, including blood tests, radiology and endoscopic evaluation for diagnosis, assessment of disease activity and to determine optimal therapeutic strategies. ‘Bedside’
