Plasma Glucosylsphingosine in GBA1 E365K, N409S, and L483P Heterozygous Mutation Carriers

Movement Disorders, EarlyView.
Abstract Background GBA1 encodes the lysosomal enzyme glucocerebrosidase, with key substrates that include glucosylceramide and glucosylsphingosine. The E365K variant is the most common variant in GBA1 that is associated with Parkinson's disease (PD) but is not associated with Gaucher disease.

Dietary Milk Sphingomyelin Reduces Systemic Inflammation in Diet-Induced Obese Mice and Inhibits LPS Activity in Macrophages

Beverages, 2017
High-fat diets (HFD) increase lipopolysaccharide (LPS) activity in the blood and may contribute to systemic inflammation with obesity. We hypothesized that dietary milk sphingomyelin (SM), which reduces lipid absorption and colitis in mice, would reduce ...

Mammalian sphingosine kinase (SphK) isoenzymes and isoform expression: challenges for SphK as an oncotarget

OncoTarget, 2017
The various sphingosine kinase (SphK) isoenzymes (isozymes) and isoforms, key players in normal cellular physiology, are strongly implicated in cancer and other diseases. Mutations in SphKs, that may justify abnormal physiological function, have not been

Enhancing Selective Brain Cancer Therapy: Integrating Nanomedicine and Molecular Dynamics to Target the Cancerous Lipid Composition

Nano Select, EarlyView.
Improving selectivity within therapeutic design is critical to ensure targeted delivery to brain tumors. Targeting the cellular membrane composition distinctive of the blood–brain barrier and brain cancer cells is explored in this review. Nanomedicine can be utilized for precise tumor recognition, and detailed mechanistic interactions of therapeutics ...

Exosomes from Human-Induced Pluripotent Stem Cell–Derived Mesenchymal Stromal Cells (hiPSC-MSCs) Protect Liver against Hepatic Ischemia/ Reperfusion Injury via Activating Sphingosine Kinase and Sphingosine-1-Phosphate Signaling Pathway

Cellular Physiology and Biochemistry, 2017
Background/Aims: This study aimed to evaluate the effects of exosomes produced by human-induced pluripotent stem cell-derived mesenchymal stromal cells (hiPSC-MSCs-Exo) on hepatic ischemia-reperfusion (I/R) injury, as well as the underlying mechanisms ...

Plasmodesmata‐located proteins: The molecular hubs in noncell‐autonomous immunity

New Plant Protection, EarlyView.
Plasmodesmata serve as critical battlefields for plant immunity, regulated by diverse proteins. This article provides a comprehensive review of the regulatory mechanisms, challenges, and future directions concerning proteins located within plasmodesmata and their roles in plant defense responses.

Intracellular localization of sphingosine kinase 1 alters access to substrate pools but does not affect the degradative fate of sphingosine-1-phosphate[S]

Journal of Lipid Research, 2010
Sphingosine kinase 1 (SK1) produces sphingosine-1-phosphate (S1P), a potent signaling lipid. The subcellular localization of SK1 can dictate its signaling function.

Advancing Extracellular Vesicle Research: A Review of Systems Biology and Multiomics Perspectives

PROTEOMICS, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are membrane‐bound vesicles secreted by various cell types into the extracellular space and play a role in intercellular communication. Their molecular cargo varies depending on the cell of origin and its functional state.

Brain Pericytes and Wnt/β‐Catenin Signaling Induce Functional Blood–Brain Barrier Phenotype in Human iPSC‐Derived Model

Small Methods, EarlyView.
This study shows that human iPSC‐derived endothelial cells acquire a functional blood–brain barrier phenotype when co‐cultured with brain pericytes and stimulated with CHIR‐99021, a Wnt/β‐catenin activator. This model recapitulates key barrier properties, inflammatory responses, and transcriptomic features of the native human BBB, offering new ...
