A New Vista of Opportunity in Diabetes Management: Natural Product‐Based β‐cell Preservation

Food Chemistry International, EarlyView.
Preserving functional β‐cells via natural products offers promising strategy for diabetes treatment. ABSTRACT A defining characteristic of diabetes is β‐cell failure, in which β‐cells cannot modulate insulin secretion to compensate for escalating insulin resistance, pushing forward disease development.

The ceramide synthase 2b gene mediates genomic sensing and regulation of sphingosine levels during zebrafish embryogenesis

eLife, 2017
Sphingosine-1-phosphate (S1P) is generated through phosphorylation of sphingosine by sphingosine kinases (Sphk1 and Sphk2). We show that sphk2 maternal-zygotic mutant zebrafish embryos (sphk2MZ) display early developmental phenotypes, including a delay ...

Sphingosine Kinase 1 Cooperates with Autophagy to Maintain Endocytic Membrane Trafficking

Cell Reports, 2016
Sphingosine kinase 1 (Sphk1) associates with early endocytic membranes during endocytosis; however, the role of sphingosine or sphingosine-1-phosphate as the critical metabolite in endocytic trafficking has not been established. Here, we demonstrate that

Sphingosine but not Sphingosine-1-phosphate Stimulates Suicidal Erythrocyte Death

Cellular Physiology and Biochemistry, 2011
Sphingosine kinase 1 phosphorylates sphingosine, which is converted to ceramide by ceramide synthetase. Ceramide triggers eryptosis, the suicidal erythrocyte death characterized by cell shrinkage and phosphatidylserine (PS) exposure at the erythrocyte surface.

Generation of Allogeneic CAR‐T Circumvents Functional Deficits in Patient‐Derived Autologous Product for Glioblastoma

International Journal of Cancer, EarlyView.
Clinical trials of chimeric antigen receptor T‐cell (CAR‐T) therapies in glioblastoma have shown limited clinical benefits. Whether this may be explained by the basal quality of CAR‐T products, which are currently generated using patient, autologous T‐cells, has been little explored.

Tumor‐Regional Immune Microenvironment: A Critical Factor in the Design of Radiotherapy–Immunotherapy Combination Trials

International Journal of Cancer, EarlyView.
ABSTRACT Clinical trials combining radiotherapy (RT) with immune checkpoint blockade (ICB) have shown improved outcomes in only a fraction of patients, and optimal strategies for integrating these modalities remain under intense investigation. With a few exceptions, phase III combination trials have yielded disappointing results.

Sphingosine kinase and sphingosine 1-phosphate in the heart: A decade of progress [PDF]

Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2013
Activation of sphingosine kinase/sphingosine 1-phosphate (SK/S1P)-mediated signaling has emerged as a critical cardioprotective pathway in response to acute ischemia/reperfusion injury. S1P is released in both ischemic pre- and post-conditioning. Application of exogenous S1P to cultured cardiac myocytes subjected to hypoxia or treatment of isolated ...

Multi‐omics biomarkers for intestinal infection and inflammation in inflammatory bowel disease: Current evidence, translational challenges, and diagnostic opportunities

Interdisciplinary Medicine, EarlyView.
Prospective multi‐site cohorts, multi‐omics profiling, and computational analysis may help identify biomarker patterns across clinical settings in IBD and superimposed infections. With further mechanistic and clinical validation, these signals could support the development of practical multi‐analyte tools for more precise diagnosis and management ...

Role of sphingosine kinase and sphingosine-1-phosphate in inflammatory arthritis

World Journal of Biological Chemistry, 2010
The importance of sphingosine kinase (SphK) and sphingosine-1-phosphate (S1P) in inflammation has been extensively demonstrated. As an intracellular second messenger, S1P plays an important role in calcium signaling and mobilization, and cell proliferation and survival.
