Anal Chim Acta 2024; 1297:342348. [PMID: 38438234 DOI: 10.1016/j.aca.2024.342348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Revised: 01/30/2024] [Accepted: 02/04/2024] [Indexed: 03/06/2024]
Abstract
Signaling lipids (SLs) play a crucial role in various signaling pathways, featuring diverse lipid backbone structures. Emerging evidence showing the biological significance and biomedical values of SLs has strongly spurred the advancement of analytical approaches aimed at profiling SLs. Nevertheless, the dramatic differences in endogenous abundances across lipid classes as well as multiple isomers within the same lipid class makes the development of a generic analytical method challenging. A better analytical method that combines comprehensive coverage and high sensitivity is needed to enable us to gain a deeper understanding of the biochemistry of these molecules in health and disease. In this study, we developed a fast and comprehensive targeted ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method for profiling SLs. The platform enables analyses of 260 metabolites covering oxylipins (isoprostanes, prostaglandins and other oxidized lipids), free fatty acids, lysophospholipids, sphingoid bases (C16, C18), platelet activating factors (C16, C18), endocannabinoids and bile acids. Various validation parameters including linearity, limit of detection, limit of quantification, extraction recovery, matrix effect, intra-day and inter-day precision were used to characterize this method. Metabolite quantitation was successfully achieved in both NIST Standard Reference Material for human plasma (NIST SRM 1950) and pooled human plasma, with 109 and 144 metabolites quantitated. The quantitation results in NIST SRM 1950 plasma demonstrated good correlations with certified or previously reported values in published literature. This study introduced quantitative data for 37 SLs for the first time. Metabolite concentrations measured in NIST SRM 1950 will serve as essential reference data for facilitating interlaboratory comparisons. The methodology established here will be the cornerstone for in-depth profiling of signaling lipids across diverse biological samples and contexts.

Abstract
Sphingosine-1-phosphate (S1P) is generated intracellularly and, when transported to the extracellular compartment, predominantly signals through S1P receptors. The S1P signalling pathway has been implicated in the pathophysiology of neurological injury following aneurysmal subarachnoid haemorrhage (aSAH). In this review, we bring together all the available data regarding the role of S1P in neurological injury following aSAH. There is agreement in the literature that S1P increases in the cerebrospinal fluid following aSAH and leads to cerebral artery vasospasm. On the other hand, the role of S1P in the parenchyma is less clear cut, with different studies arguing for beneficial and deleterious effects. A parsimonious interpretation of this apparently conflicting data is presented. We discuss the potential of S1P receptor modulators, in clinical use for multiple sclerosis, to be repurposed for aSAH. Finally, we highlight the gaps in our knowledge of S1P signalling in humans, the clinical challenges of targeting the S1P pathway after aSAH and other research priorities.

A new quantitative method for pseudouridine and uridine in human serum and its clinical application in acute myeloid leukemia. J Pharm Biomed Anal 2022; 219:114934. [PMID: 35839582 DOI: 10.1016/j.jpba.2022.114934] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Revised: 07/04/2022] [Accepted: 07/06/2022] [Indexed: 11/21/2022]
Abstract
Pseudouridine, a C-C glycosidic isomer of uridine, is derived from uridine via isomerization, and pseudouridylation is the most common post-transcriptional modification. Our previous study shows pseudouridine may serve an important role in acute myeloid leukemia (AML). The clinical value of pseudouridine and uridine is hampered by the lack of a quantitative methods with high sensitivity, specificity, and stability. Here, we established a supercritical fluid chromatography-tandem triple quadrupole mass spectrometry (SFC-TQ-MS)-based method to quantitate serum pseudouridine and uridine simultaneously. The procedure involves protein precipitation of sample, extraction with solid phase extraction (SPE) plate, 5-min SFC separation by applying gradient elution on a Acquity UPC2 Torus DIOL column, and analysis by TQ-MS using well-characterized calibration standards. After validation, the method was used to measure pseudouridine and uridine concentrations in 143 serum samples from healthy controls (HCs) and AML patients to evaluate their prognostic potential. The successfully validated assay had a linear range of 5-5000 ng/mL, accuracies between 97 % and 102 %, and intra- and inter-assay imprecision <10 %. Compared to HCs, pseudouridine was raised significantly, while uridine was curtailed severely in patients with AML. With a median concentration of 671.4 ng/mL as the prognostic cut-off value, high level pseudouridine independently predicted poor survival of AML patients. Quantification of serum pseudouridine and uridine by SFC-TQ-MS provides an analytically sensitive and reproducible method for clinical diagnosis, and high concentration of pseudouridine is an independent prognostic factor for patients with AML.

Validated LC-MS/MS method of Sphingosine 1-phosphate quantification in human serum for evaluation of response to radiotherapy in lung cancer. Thorac Cancer 2020; 11:1443-1452. [PMID: 32233070 PMCID: PMC7262919 DOI: 10.1111/1759-7714.13409] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2020] [Revised: 03/07/2020] [Accepted: 03/09/2020] [Indexed: 12/13/2022] Open
Abstract
Background Sphingosine 1‐phosphate (S1P), a bioactive lipid, has been shown to mediate cancer processes. Therefore, accurate qualitative and quantitative determination is essential. The current assay method is still cumbersome to be of practical use worldwide and the aim of this study was therefore to develop a fast, accurate, precise and efficient LC‐MS/MS method for targeted analyses of S1P in serum samples. Methods Liquid chromatography‐tandem mass spectrometry (LC‐MS/MS) is an established method used for monitoring and analyzing S1P levels in serum. We determined the level of serum S1P in 256 patients with lung cancer and 36 healthy donors, and used Spearman';s rank correlation analysis to evaluate the difference in serum S1P levels between radiotherapy and nonradiotherapy patients. Results Standard curves were linear over ranges of 25–600 ng/mL for S1P with correlation coefficient (r2) greater than 0.9996. The lower limit of quantifications (LLOQs) was 25 ng/mL. The intra‐ and interbatch precisions and accuracy was less than 10% for S1P. The recoveries of the method were found to be 80%–98%. Serum S1P levels in healthy donors were different from those in patients (P < 0.001). Of 256 lung cancer patients, 124 (48.4%) received radiotherapy and were identified to have concomitant low serum S1P levels (222.13 ± 48.63), whereas 132 (51.6%) who had not received radiotherapy were identified to have high levels (315.16 ± 51.06). The serum S1P levels were therefore associated with radiotherapy (Spearman's Rho = −0.653, P < 0.001). Conclusions Our results indicated that this new LC‐MS/MS method is rapid, sensitive, specific and reliable for the quantification of S1P levels in serum samples. The level of S1P in serum samples of patients with lung cancer who received radiotherapy was significantly lower than that in patients who did not receive radiotherapy. Key points An improved method was established to quantify S1P levels in human serum by LC‐MS/MS, which enabled the change in serum S1P levels in lung cancer patients to be monitored, in combination with radiotherapy, and their clinical significance to be analyzed.

Apolipoprotein M Inhibits Angiogenic and Inflammatory Response by Sphingosine 1-Phosphate on Retinal Pigment Epithelium Cells. Int J Mol Sci 2017; 19:ijms19010112. [PMID: 29301231 PMCID: PMC5796061 DOI: 10.3390/ijms19010112] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2017] [Revised: 12/20/2017] [Accepted: 12/28/2017] [Indexed: 01/04/2023] Open
Abstract
Sphingosine 1-phosphate (S1P) is a potent lipid mediator that modulates inflammatory responses and proangiogenic factors. It has been suggested that S1P upregulates choroidal neovascularization (CNV) and may be deeply involved in the pathogenesis of exudative age-related macular degeneration (AMD). Recent studies have suggested that apolipoprotein M (ApoM), a carrier protein for S1P, modulates the biological properties of S1P in the pathogenesis of atherosclerosis. However, the role of ApoM/S1P in AMD has not been explored. We investigated the effect of S1P on proangiogenic factors in human retinal pigment epithelium (RPE) cell lines in vitro. S1P promoted the expression of vascular endothelial growth factor in RPE cells. Hypoxia inducible factor-1α expression was also upregulated. These S1P-induced enhancements in growth factors and chemotactic cytokines in RPE cells were significantly inhibited by ApoM treatment. Additionally, in vivo experiments using a laser-induced CNV murine model demonstrated that intravitreal ApoM injection significantly reduced the progression of CNV formation. Although the detailed mechanisms remain to be elucidated, the present results provide a novel potential therapeutic target for AMD, and demonstrate a suppressive role for ApoM and S1P in the pathology of CNV progression.
