The synthesis of a series of vinylated analogues of sphingosine-1-phosphate together with their unambiguous configurational assignment by VCD methods is reported. Among them, compound can irreversibly inhibit human sphingosine-1-phosphate lyase (hS1PL) while behaving also as an enzyme substrate. These findings, together with the postulated mechanism for S1PL activity, reinforce the role of as a new mechanism-based hS1PL inhibitor.

Urothelial Urinary Bladder Cancer Is Characterized by Stage-Dependent Aberrations in Metabolism of Bioactive Sphingolipids.
Int J Mol Sci
November 2024
Department of Physiology, Medical University of Bialystok, Mickiewicza 2c, 15-222 Białystok, Poland.
Article Synopsis
- This study investigates the metabolism of bioactive sphingolipids in bladder cancer, focusing on differences between non-muscle-invasive (NMIBC) and muscle-invasive (MIBC) tumors in 48 patients.
- Results showed that MIBC tumors had increased levels of sphingosine-1-phosphate (S1P) and ceramide compared to healthy tissue and NMIBC tumors, indicating stage-dependent changes in sphingolipid metabolism.
- The researchers suggest that the dysregulation of S1P metabolism may play a role in the progression of urothelial bladder cancer as it transitions from NMIBC to MIBC.

Sphingosine phosphate lyase insufficiency syndrome (SPLIS) is a genetic disease associated with renal, endocrine, neurological, skin and immune defects. SPLIS is caused by inactivating mutations in SGPL1, which encodes sphingosine phosphate lyase (SPL). SPL catalyzes the irreversible degradation of the bioactive sphingolipid sphingosine-1-phosphate (S1P), a key regulator of lymphocyte egress.

Sphingosine-1-phosphate (S1P) is a ubiquitous lipid mediator, acting via specific G-protein-coupled receptors (GPCR) and intracellularly. Previous work has shown that deletion of S1P lyase caused a chronic elevation of cytosolic [Ca] and enhanced Ca storage in mouse embryonic fibroblasts. Here, we studied the role of sphingosine kinase (SphK)-1 in Ca signaling, using two independently generated EA.

Article Synopsis
- Sphingosine-1-phosphate lyase insufficiency syndrome (SPLIS) is a rare genetic disorder linked to severe health issues like nephrotic syndrome, adrenal insufficiency, and various systemic symptoms, primarily caused by mutations in the SGPL1 gene.
- A study of 76 SPLIS patients found that overall survival is around 50%, with survival influenced by factors such as age at diagnosis, organ involvement, whether the patient received a kidney transplant, and specific SGPL1 genotypes.
- Children diagnosed with SPLIS nephropathy before age one have a significantly worse survival rate compared to those diagnosed after one year, highlighting the importance of early diagnosis and potential interventions.
Down-regulation of key regulatory factors in sphingosine-1-phosphate (S1P) pathway in human lung fibroblasts transfected with selected microRNAs.

Sphingosine 1 phosphate (S1P) is involved in the pathogenesis of asthma by stimulation of the alpha-smooth muscle actin (SMA) expression and remodeling of fibroblasts. This study was designed to determine the effects of selected micro RNAs in regulation of S1P and related metabolic pathways in a human lung fibroblast cell line. The fibroblast cell line (CIRC-HLF, C580) was cultured and transfected with individual viral vectors carrying miR124, mi125b, mi133b or mi130a.
