MetabolomicsSphingosine-1-phosphate receptor 1 promotes ovarian cancer tumorsphere proliferation and metastasis
Despite extensive clinical endeavors to enhance high-grade serous ovarian cancer (HGSOC) detection and treatment, an alarming half of diagnosed women succumb annually to this disease. Significantly, nearly all HGSOC cases manifest ascites at diagnosis, a poor prognostic indicator. Malignant ascites ...

MetabolomicsTetrandrine regulates NAADP-mediated calcium signalling 1 through a novel LIMP-2-dependent, sphingosine-mediated mechanism.
Tetrandrine (Tet) is an highly potent inhibitor of Ebola virus replication by blocking NAADP51 dependent calcium release through endolysosomal two-pore channels (TPCs) and a moderately potent anti-tumor agent. Using a clickable, photoaffinity probe of Tet, we identified lysosomal integral membrane p...

MetabolomicsMetabolomic Analysis Reveals an Important Role of Sphingosine 1-phosphate in the Development of HFMD due to EV-A71 Infection

Hand, foot, and mouth disease (HFMD) is a serious pediatric infectious disease that causes immeasurable physical and mental health burdens. Currently, there is a lack of information on the mechanisms of HFMD severity and early diagnosis. We performed metabolomic profiling of sera from 84 Enterovi...

TranscriptomicsSphingosine-1-phosphate induces pro-remodelling response in airway smooth muscle cells
Background: Increased proliferation of airway smooth muscle (ASM) cells leading to hyperplasia and increased ASM mass is one of the most characteristic features of airway remodelling in asthma. A bioactive lipid, sphingosine-1-phosphate (S1P), has been suggested to affect airway remodelling by stimu...

TranscriptomicsTranscription profiling of human male embryonic stem cell line line grown in standard conditions, with feeder cells and treated with the signalling sphingolipid sphingosine-1-phosphate reveals S1P mediates key targets associated with survival, proliferation and pluripotency
Human embryonic stem cells (hESCs) replicate by the process of self-renewal, whilst maintaining their pluripotency. Understanding the pathways involved in the regulation of this self-renewal process will assist in developing fully-defined conditions for the proliferation of hESCS required for the...

TranscriptomicsSphingosine survival response of Staphylococcus aureus and Staphylococcus epidermidis
S. aureus and S. epidermidis were challenged with D-sphingosine, an antimicrobial lipid similar to sphingosines found in the major staphylococcal niche- human skin. Comparison of responses was used to identify resistance mechanisms and likely mode of action

TranscriptomicsSphingosine-1-phosphate phosphatase 1 regulates keratinocyte differentiation and epidermal homeostasis
Sphingosine 1-phosphate (S1P) is a bioactive lipid whose levels are tightly regulated by its synthesis and degradation. Intracellularly, S1P is dephosphoryled by the actions of two S1P-specific phosphatases, sphingosine 1-phosphate phosphatase 1 and 2. To identify the physiologic functions of S1P p...

TranscriptomicsA Sphingosine 1-Phosphate 1 Receptor Agonist Modulates Brain Death-Induced Neurogenic Pulmonary Injury
Lung transplantation remains the only viable therapy for patients with end-stage lung disease; however, full utilization of this treatment strategy is severely compromised by the lack of donor lung availability. For example, the vast majority of donor lungs available for transplantation are obtained...

TranscriptomicsS1P lyase deficiency disrupts lipid homeostasis in liver
The cleavage of sphingoid base phosphates by sphingosine-1-phosphate (S1P) lyase to produce phosphoethanolamine and a fatty aldehyde is the final degradative step in the sphingolipid metabolic pathway. We have studied mice with an inactive S1P lyase gene and have found that, in addition to the expec...

TranscriptomicsSphingosine-1-phosphate Phosphatase 2 Regulates Pancreatic Islet B-cell Endoplasmic Reticulum Stress and Proliferation
Sphingosine-1-phosphate (S1P) is a sphingolipid metabolite that regulates basic cell functions through metabolic and signaling pathways. Intracellular metabolism of S1P is controlled, in part, by two homologous S1P phosphatases, 1 and 2, which are encoded by Sgpp1 and Sgpp2, respectively. S1P phosph...
