[PMID: 31683697 PMCID: PMC6896196 DOI: 10.3390/cancers11111696] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2019] [Revised: 10/25/2019] [Accepted: 10/30/2019] [Indexed: 12/25/2022] Open
Abstract
Sphingosylphosphorylcholine (SPC) is a unique type of lysosphingolipid found in some diseases, and has been studied in cardiovascular, neurological, and inflammatory phenomena. In particular, SPC’s studies on cancer have been conducted mainly in terms of effects on cancer cells, and relatively little consideration has been given to aspects of tumor microenvironment. This review summarizes the effects of SPC on cancer and tumor microenvironment, and presents the results and prospects of modulators that regulate the various actions of SPC.

Abstract
Sphingosylphosphorylcholine (SPC), an important lipid mediator in blood, inhibits the proliferation and migration of various cancer cells. However, its effect as a cell-specific sphingolipid in breast cancer cells is still unknown. Here, we showed that SPC promoted autophagy and apoptosis in triple-negative breast cancer MDA-MB-231 cells. Autophagy worked as a negative regulator of apoptosis-induced by SPC. Mechanistically, SPC mediated apoptosis via activating c-Jun N-terminal kinase (JNK). Meanwhile, p38MAPK (p38) and protein kinase B (PKB or AKT) signaling pathways were also activated to inhibit apoptosis, suggesting that SPC could evoke multiple signaling pathways to modulate cell apoptosis. In addition, the crosstalk between autophagy, p38, AKT and JNK is that autophagy, p38, and AKT attenuated the JNK. AKT and p38 were in the downstream of autophagy, which is autophagy/AKT/p38 signaling evoked by SPC to antagonize JNK signaling and subsequent apoptosis. Although the pathways that antagonize apoptosis were evoked, the cells eventually reached apoptosis by SPC. Therefore, the combination with pharmacological autophagy inhibitors would be a more effective therapeutic strategy for eliminating breast cancer cells by SPC.

Abstract
Background The prognosis of pancreatic cancer (PC) is one of the poorest among all cancers, due largely to the lack of methods for screening and early detection. New biomarkers for identifying high-risk or early-stage subjects could significantly impact PC mortality. The goal of this study was to find metabolic biomarkers associated with PC by using a comprehensive metabolomics technology to compare serum profiles of PC patients to healthy control subjects. Methods A non-targeted metabolomics approach based on high-resolution, flow-injection Fourier transform ion cyclotron resonance mass spectrometry (FI-FTICR-MS) was used to generate comprehensive metabolomic profiles containing 2478 accurate mass measurements from the serum of Japanese PC patients (n=40) and disease-free subjects (n=50). Targeted flow-injection tandem mass spectrometry (FI-MS/MS) assays for specific metabolic systems were developed and used to validate the FI-FTICR-MS results. A FI-MS/MS assay for the most discriminating metabolite discovered by FI-FTICR-MS (PC-594) was further validated in two USA Caucasian populations; one comprised 14 PCs, six intraductal papillary mucinous neoplasims (IPMN) and 40 controls, and a second comprised 1000 reference subjects aged 30 to 80, which was used to create a distribution of PC-594 levels among the general population. Results FI-FTICR-MS metabolomic analysis showed significant reductions in the serum levels of metabolites belonging to five systems in PC patients compared to controls (all p<0.000025). The metabolic systems included 36-carbon ultra long-chain fatty acids, multiple choline-related systems including phosphatidylcholines, lysophosphatidylcholines and sphingomyelins, as well as vinyl ether-containing plasmalogen ethanolamines. ROC-AUCs based on FI-MS/MS of selected markers from each system ranged between 0.93 ±0.03 and 0.97 ±0.02. No significant correlations between any of the systems and disease-stage, gender, or treatment were observed. Biomarker PC-594 (an ultra long-chain fatty acid), was further validated using an independently-collected US Caucasian population (blinded analysis, n=60, p=9.9E-14, AUC=0.97 ±0.02). PC-594 levels across 1000 reference subjects showed an inverse correlation with age, resulting in a drop in the AUC from 0.99 ±0.01 to 0.90 ±0.02 for subjects aged 30 to 80, respectively. A PC-594 test positivity rate of 5.0% in low-risk reference subjects resulted in a PC sensitivity of 87% and a significant improvement in net clinical benefit based on decision curve analysis. Conclusions The serum metabolome of PC patients is significantly altered. The utility of serum metabolite biomarkers, particularly PC-594, for identifying subjects with elevated risk of PC should be further investigated.

Abstract
The goal of this study was to evaluate the possible protective effects of sphingosylphosphorylcholine (SPC) against cholestatic oxidative stress and liver damage in the common bile duct ligated rats. Fifty-six animals were included in each of the following 7 groups: control, SPC control, phosphate-buffered solution control, sham operated, bile duct ligation (BDL), BDL plus phosphate-buffered solution, and BDL plus SPC. Sphingosylphosphorylcholine was administered 14 days at a daily dose of 2 microm/mL intraperitoneally. The severity of cholestasis and hepatic injury was determined by changes in the plasma enzyme activities of aspartate aminotransferase, alanine aminotransferase, gama glutamin transferase, and levels of total bilirubin and direct bilirubin. Malondialdehyde, nitric oxide, and superoxide dismutase were determined to evaluate the oxidative status in the liver tissue. Myeloperoxidase activity and levels of tissue hydroxyproline were determined to assess neutrophil activation and collagen accumulation, respectively. Treatment with SPC markedly reduced serum transaminase activities as compared to BDL rats. Sphingosylphosphorylcholine also inhibited the increase in liver malondialdehyde; nitric oxide levels significantly and also attenuated the depletion of superoxide dismutase in the liver after BDL. Similarly, the increase in tissue myeloperoxidase activity and hydroxyproline owing to BDL was also attenuated by the SPC treatment. These data were supported by histopathologic findings. The alpha-smooth muscle actin-positive cells in the BDL were observed to be reduced with the SPC treatment. In conclusion, these findings suggested that SPC can attenuate hepatic damage in extrahepatic cholestasis by prevention of oxidative stress, and inflammatory process. All these findings suggest that SPC may be a promising new therapeutic agent for cholestatic liver injury.

Phorbol 12-myristate 13-acetate inhibits FRO anaplastic human thyroid cancer cell proliferation by inducing cell cycle arrest in G1/S phase: evidence for an effect mediated by PKCdelta. Mol Cell Endocrinol 2008; 292:26-35. [PMID: 18541361 DOI: 10.1016/j.mce.2008.04.018] [Citation(s) in RCA: 24] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2008] [Revised: 04/30/2008] [Accepted: 04/30/2008] [Indexed: 01/06/2023]
Abstract
Phorbol 12-myristate 13-acetate (PMA) is known to affect a variety of cellular processes, including cell proliferation, differentiation, and migration. PMA has been shown to promote antiproliferative and antimigratory effects in many types of cancer cells. Our findings show that PMA induced a strong antiproliferative effect in two anaplastic (FRO and ARO) and one follicular (ML-1) thyroid cancer cell lines, and increased the fraction of FRO cells in G1 phase of the cell cycle. The fractions in the S and G2 phases were decreased. Moreover, PMA evoked a significant increase in the levels of the cell cycle regulators p21Waf1/Cip1 and p27Kip1. The levels of cyclin D3 and the cyclin-dependent kinases cdk4 and cdk6 decreased, as did the phosphorylation of the Rb-protein. PMA did not induce apoptosis. PMA stimulated the translocation of protein kinase C (PKC) alpha, betaI and delta isoforms to the cell membrane. PKCdelta small interfering RNA attenuated the PMA-induced antiproliferative effect and prevented the upregulation of p21Waf1/Cip1 and p27Kip1. Prolonged stimulation with PMA decreased the phosphorylation of mitogen-activated protein (MAP) kinase. PMA also decreased the phosphorylation of Akt and evoked a biphasic change in the phosphorylation of the forkhead box class-O protein (FOXO): an increase in phosphorylation, followed by a dephosphorylation. In addition, PMA inhibited FRO, ARO and ML-1 cell migration toward serum. The inactive phorbol ester analog 4alpha-phorbol and the diacylglycerol analog 1,2-dioctanoyl-sn-glycerol were without an effect on proliferation and migration. The results indicate that PMA is an effective inhibitor of thyroid cancer cell proliferation and migration by a mechanism involving PKC-MAP kinase/Akt and FOXO signaling.
