GLS1 Orchestrates Exosome‐Mediated Tumor‐Endothelial Communication to Facilitate Angiogenesis

Advanced Science, Volume 13, Issue 41, 22 July 2026.
This study reveals a previously unappreciated, non‐metabolic function of GLS1 in the control of tumor angiogenesis via exosome‐mediated CAV1‐TNC signaling, indicating that therapeutic targeting of GLS1 may offer a dual benefit by simultaneously suppressing tumor metabolic activity and angiogenic processes in head and neck cancer. ABSTRACT Glutaminase 1

Conformational changes of apoB-100 in SMase-modified LDL mediate formation of large aggregates at acidic pH[S]

Journal of Lipid Research, 2012
During atherogenesis, the extracellular pH of atherosclerotic lesions decreases. Here, we examined the effect of low, but physiologically plausible pH on aggregation of modified LDL, one of the key processes in atherogenesis.

Exercise‐Induced Extracellular Vesicles as Mediators of Mitochondrial Biogenesis and Insulin Sensitivity in Metabolic Adaptation

Endocrinology, Diabetes &Metabolism, Volume 9, Issue 4, July 2026.
Exercise stimulates the release of extracellular vesicles from metabolically active tissues. These vesicles transport regulatory cargos, including microRNAs, proteins, lipids, and metabolites, to target organs such as skeletal muscle, adipose tissue, liver, and vascular tissues.

Sphingolipid Metabolism and Neutral Sphingomyelinases [PDF]

, 2013
Sphingolipids are an important class of lipid molecules that play fundamental roles in our cells and body. Beyond a structural role, it is now clearly established that sphingolipids serve as bioactive signaling molecules to regulate diverse processes including inflammatory signaling, cell death, proliferation, and pain sensing. Sphingolipid metabolites

Absorption and lipoprotein transport of sphingomyelin

Journal of Lipid Research, 2006
Dietary sphingomyelin (SM) is hydrolyzed by intestinal alkaline sphingomyelinase and neutral ceramidase to sphingosine, which is absorbed and converted to palmitic acid and acylated into chylomicron triglycerides (TGs).

Sleep deprivation aggravates hepatocytes steatosis and insulin resistance by regulating exosomal microRNAs

Interdisciplinary Medicine, Volume 4, Issue 4, July 2026.
Sleep deprivation accelerates the progression of MASLD and IR by up‐regulating the expression of miR‐3572‐5p and down‐regulating the expression of miR‐183‐5p in circulating exosomes, thereby inhibiting fatty acid β‐oxidation and disrupting insulin signaling pathways. Abstract Sleep deprivation (SD) threatens human health and increases the prevalence of

Enterotoxin Production of Bacillus thuringiensis Isolates From Biopesticides, Foods, and Outbreaks

Frontiers in Microbiology, 2018
While the relevance of Bacillus (B.) cereus as a major cause of gastroenteritis is undisputed, the role of the closely related B. thuringiensis in foodborne disease is unclear. B. thuringiensis strains frequently harbor enterotoxin genes.

Plasma Membrane Lipid Domains as Platforms for Vesicle Biogenesis and Shedding?

Biomolecules, 2018
Extracellular vesicles (EVs) contribute to several pathophysiological processes and appear as emerging targets for disease diagnosis and therapy. However, successful translation from bench to bedside requires deeper understanding of EVs, in particular ...
