Low levels of human leukocyte antigen-DR (HLA-DR) in tumors have been shown to negatively influence prognosis and response to ICIs. Lysophosphatidic acid (LPA) is produced in large amounts by melanoma and is abundantly present in the tumor microenvironment. LPA induces the release of various cytokines and chemokines from tumor cells, which affect cancer development, metastasis, and tumor immunity. In the present study, we investigated the role of LPA-induced IL-10 release in regulating HLA-DR expression and the underlying mechanisms in human melanoma cells. We showed that LPA (0.001–10 μM) dose-dependently increased DR6 transcript levels through activating LPAR1 in HEK293T cells. Knockdown of NF-κB1 abrogated the LPA-increased DR6 expression without affecting basal DR6 expression in both A2058 and A375 melanoma cell lines. LPA (10 µM) significantly increased IL-10 transcripts in A2058 and A375 melanoma cells, the effect was abolished by pharmacological inhibition of LPAR1 or knockdown of DR6. We found a statistically significant correlation between the expression of LPAR1, DR6 and IL-10 in human melanoma tissue and an association between increased expression of LPAR1 and reduced effectiveness of ICI therapy. We demonstrated that LPA (10 µM) markedly suppressed HLA-DR expression in both A375 and A2058 melanoma cells via activating the LPAR1-DR6-IL-10 pathway. These data suggest that the LPAR1-DR6-IL-10 autocrine loop could constitute a novel mechanism used by tumor cells to evade immunosurveillance by decreasing HLA-DR expression.}, year = {2025}, eissn = {1745-7254}, pages = {222-230}, orcid-numbers = {Major, Enikő/0000-0001-5854-9395;

Here, we report that adding unsaturated LPA to standard mouse chow also increased the content of reactive oxygen species and oxidized phospholipids (OxPLs) in jejunum mucus. To determine the role of intestinal autotaxin, enterocyte-specific Ldlr-/-/Enpp2 KO (in-testinal KO) mice were generated. In control mice, the WD increased enterocyte Enpp2 expression and raised autotaxin levels. Ex vivo, addition of OxPL to jejunum from Ldlr-/- mice on a chow diet induced expression of Enpp2. In control mice, the WD raised OxPL levels in jejunum mucus and decreased gene expression in enterocytes for a number of peptides and proteins that affect antimicrobial activity. On the WD, the control mice developed elevated levels of lipopolysaccharide in jejunum mucus and plasma, with increased dyslipidemia and increased athero-sclerosis. All these changes were reduced in the in-testinal KO mice. We conclude that the WD increases the formation of intestinal OxPL, which i) induce enterocyte Enpp2 and autotaxin resulting in higher enterocyte LPA levels; that ii) contribute to the formation of reactive oxygen species that help to maintain the high OxPL levels; iii) decrease intestinal antimicrobial activity; and iv) raise plasma lipopoly-saccharide levels that promote systemic inflammation and enhance atherosclerosis.}, keywords = {ATHEROSCLEROSIS; Small intestine; oxidized phospholipids; Lysophosphatidic acid; Lysophospholipase D; apolipoprotein A-I mimetic peptides; transgenic tomatoes expressing the apoA-I mimetic peptide 6F}, year = {2023}, eissn = {1539-7262}, orcid-numbers = {Wang, Huan/0000-0003-1115-143X} } @article{MTMT:33856644, title = {Pathogenesis and Treatment of Pruritus Associated with Chronic Kidney Disease and Cholestasis}, url = {https://m2.mtmt.hu/api/publication/33856644}, author = {Kim, Jin-Cheol and Shim, Won-Sik and Kwak, In-Suk and Lee, Dong-Hun and Park, Jin-Seo and Lee, So-Yeon and Kang, Seok-Young and Chung, Bo-Young and Park, Chun-Wook and Kim, Hye-One}, doi = {10.3390/ijms24021559}, journal-iso = {INT J MOL SCI}, journal = {INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES}, volume = {24}, unique-id = {33856644}, issn = {1661-6596}, abstract = {Itching is an unpleasant sensation that provokes the desire to scratch.

Biomarkers are analytic indicators of the biological and disease processes within an individual that can be accurately and reproducibly measured. The field of biomarkers in SSc is complex as recent studies have implicated at least 240 pathways and dysregulated proteins in SSc pathogenesis. Anti-nuclear antibodies (ANA) are classical biomarkers with well-described clinical classifications and are present in more than 90% of SSc patients and include anti-centromere, anti-Th/To, anti-RNA polymerase III, and anti-topoisomerase I antibodies. Transforming growth factor-beta (TGF-beta) is central to the fibrotic process of SSc and is intimately intertwined with other biomarkers. Tyrosine kinases, interferon-1 signaling, IL-6 signaling, endogenous thrombin, peroxisome proliferator-activated receptors (PPARs), lysophosphatidic acid receptors, and amino acid metabolites are new biomarkers with the potential for developing new therapeutic agents. Other biomarkers implicated in SSc-ILD include signal transducer and activator of transcription 4 (STAT4), CD226 (DNAX accessory molecule 1), interferon regulatory factor 5 (IRF5), interleukin-1 receptor-associated kinase-1 (IRAK1), connective tissue growth factor (CTGF), pyrin domain containing 1 (NLRP1), T-cell surface glycoprotein zeta chain (CD3 zeta) or CD247, the NLR family, SP-D (surfactant protein), KL-6, leucine-rich alpha 2-glycoprotein-1 (LRG1), CCL19, genetic factors including DRB1 alleles, the interleukins (IL-1, IL-4, IL-6, IL-8, IL-10 IL-13, IL-16, IL-17, IL-18, IL-22, IL-32, and IL-35), the chemokines CCL (2,3,5,13,20,21,23), CXC (8,9,10,11,16), CX3CL1 (fractalkine), and GDF15.

LPA may regulate microglial activation, which is important in the pathogenesis of NPSLE, as well as blood-brain-barrier weakening and depression-like behaviours.Neuropsychiatric systemic lupus erythematosus (NPSLE) is an incurable disease characterised by neuropsychiatric symptoms, particularly depression. Novel therapeutic options for NPSLE are urgently needed. Several previous reports have suggested that both microglial activation and impaired neurogenesis may be involved in the progression of depression. In contrast, the administration of lysophosphatidic acid (LPA) ameliorates depression and anxiety. Therefore, in the present study, we determined whether treatment with LPA affects microglial activation, impaired neurogenesis, and abnormal behaviour in MRL/lpr mice. In both tail suspension test and forced swim test, the MRL/lpr mice exhibited a significant increase in total immobility time compared with MRL/+ mice. Treatment with LPA significantly suppressed the prolonged immobility time in MRL/lpr mice. In contrast, pretreatment with ki16425 (a specific antagonist of LPA receptor 1 and 3) significantly reversed the effects of LPA. Furthermore, MRL/lpr mice exhibited impairments in spatial working memory and visual cognitive memory, which were suppressed by LPA treatment. The expression levels of TMEM119, CD68, GFAP, and caspase-3 in the hippocampus and prefrontal cortex of MRL/lpr mice were significantly higher than those in MRL/+ mice. Treatment with LPA inhibited these increases in MRL/lpr mice. Pretreatment with ki16425 reversed LPA-mediated inhibition of microglial activation. The quantity of sodium fluorescein that leaked into the brain tissues in MRL/lpr mice were significantly higher than that in MRL/+ mice. Treatment with LPA tended to decrease the sodium fluorescein leakage. These findings suggest that treatment with LPA may regulate microglial activation, which is important in the pathogenesis of NPSLE, as well as blood-brain-barrier weakening and abnormal behaviour.}, keywords = {DEPRESSION; neuroinflammation; microglia; LPA; NPSLE}, year = {2023}, eissn = {1365-2249}, pages = {81-92}, orcid-numbers = {Nagata, Wataru/0000-0002-4343-8315} } @article{MTMT:34282714, title = {Differential targeting of lysophosphatidic acid LPA1, LPA2, and LPA3 receptor signalling by tricyclic and tetracyclic antidepressants.}, url = {https://m2.mtmt.hu/api/publication/34282714}, author = {Olianas, Maria C. and Dedoni, Simona and Onali, Pierluigi}, doi = {10.1016/j.ejphar.2023.176064}, journal-iso = {EUR J PHARMACOL}, journal = {EUROPEAN JOURNAL OF PHARMACOLOGY}, volume = {959}, unique-id = {34282714}, issn = {0014-2999}, abstract = {We previously reported that in different cell types antidepressant drugs activate lysophosphatidic acid (LPA) LPA1 receptor to induce proliferative and prosurvival responses. Here, we further characterize this unique action of antidepressants by examining their effects on two additional LPA receptor family members, LPA2 and LPA3. Human LPA1-3 receptors were stably expressed in HEK-293 cells (HEK-LPA1,-LPA2 and -LPA3 cells) and their functional activity was determined by Western blot and immunofluorescence. LPA effectively stimulated the phosphorylation of extracellular signal-regulated protein kinases 1 and 2 (ERK1/2) in HEK-LPA1,-LPA2, and-LPA3 cells. The tricyclic antidepressants amitriptyline, clomipramine, imipramine and desipramine increased phospho-ERK1/2 levels in HEK-LPA1 and -LPA3 cells but were relatively poor agonists in LPA2-expressing cells. The tetracyclic antidepressants mianserin and mirtazapine were active at all three LPA receptors. When combined with LPA, both amitriptyline and mianserin potentiated Gi/o-mediated phosphorylation of ERK1/2 induced by LPA in HEK-LPA1,-LPA2 and-LPA3 cells, CHO-K1 fibroblasts and HT22 hippocampal neuroblasts. This potentiation was associated with enhanced phosphorylation of CREB and S6 ribosomal protein, two molecular targets of activated ERK1/2. The antidepressants also potentiated LPA-induced Gq/11-mediated phosphorylation of AMP-activated protein kinase in HEK-LPA1 and -LPA3 cells. Conversely, amitriptyline and mianserin were found to inhibit LPA-induced Rho activation in HEK-LPA1 and LPA2 cells.

Lysophosphatidic acids (LPAs) are bioactive phospholipids elevated in inflammation. The aim of this study was to test whether LPA inhibits GLP-1 secretion in vitro and in vivo. GLUTag L-cells were treated with various LPA species, with or without LPA receptor (LPAR) antagonists, and media GLP-1 levels, cellular cyclic AMP and calcium ion concentrations, and DPP4 activity levels were analyzed. Mice were injected with LPA, with or without LPAR antagonists, and serum GLP-1 and DPP4 activity were measured. GLUTag GLP-1 secretion was decreased similar to 70-90% by various LPAs. GLUTag expression of Lpar1, 2, and 3 was orders of magnitude higher than Lpar4, 5, and 6, implicating the former group in this effect. In agreement, inhibition of GLP-1 secretion was reversed by the LPAR1/3 antagonist Ki16425, the LPAR1 antagonists AM095 and AM966, or the LPAR2 antagonist LPA2-antagonist 1. We hypothesized involvement of G alpha(i)-mediated LPAR activity, and found that intracellular cyclic AMP and calcium ion concentrations were decreased by LPA, but restored by Ki16425. Mouse LPA injection caused an similar to 50% fall in circulating GLP-1, although only LPAR1 or LPAR1/3 antagonists, but not LPAR2 antagonism, prevented this.

ATX was inhibited in vivo in DNBS [dinitrobenzene sulfonic acid]-induced colitis mice, which were evaluated for colonic inflammation and fibrosis. 3T3-L1 cells and primary colonic fibroblasts were used in vitro to investigate the interaction between MAT and intestinal fibrosis, as well as the molecular mechanism underlying this interaction. Results MAT adjacent to the fibrostenotic intestine in CD patients showed an activated ATX-LPA axis. An in vivo study indicated that inhibition of ATX was associated with the improvement of morphology and function of diseased MAT, which was combined with ameliorated intestinal inflammation and fibrosis in DNBS-instilled mice. In vitro studies showed that hypoxia stimulated adipocyte ATX expression and that LPA stabilized adipocyte HIF-1 alpha protein, forming an ATX-LPA-HIF-1 alpha amplification loop and aggravating adipocyte dysfunction. LPA secreted by adipocytes bound to LPA(1) on the surface of fibroblasts, promoted their proliferation and differentiation, and increased the expression of fibrosis-related factors. Conclusions The ATX-LPA axis regulated intestinal fibrosis by influencing the proliferation and differentiation of intestinal fibroblasts. Inhibiting this axis may be a therapeutic target for intestinal fibrosis in CD.}, keywords = {Lysophosphatidic acid; AUTOTAXIN; intestinal fibrosis; Mesenteric adipose tissue}, year = {2022}, eissn = {1876-4479} } @article{MTMT:33008120, title = {Preclinical detection of lysophosphatidic acid: A new window for ovarian cancer diagnostics}, url = {https://m2.mtmt.hu/api/publication/33008120}, author = {Huang, Xueyan and Feng, Bin and Liu, Meihui and Liu, Zuyuan and Li, Shi and Zeng, Wenbin}, doi = {10.1016/j.talanta.2022.123561}, journal-iso = {TALANTA}, journal = {TALANTA}, volume = {247}, unique-id = {33008120}, issn = {0039-9140}, abstract = {Ovarian cancer, a highly metastatic disease characterized by widespread peritoneal and ascites dissemination, is the leading cause of death from gynecological malignancies and poses a serious threat to women's lives.

Recent studies have shown that lysophosphatidic acid (LPA) can maintain intestinal epithelial renewal in vitro and conditional deletion of Lpar5 (Lpar5(iKO)) in mice ablates the intestinal epithelium and increases morbidity. In contrast, constitutive Lpar5 deletion (Lpar5(cKO)) does not cause a defect in intestinal crypt regeneration. In this study, we investigated whether another LPA receptor (LPAR) compensates for constitutive loss of LPA(5) function to allow regeneration of intestinal epithelium. In Lpar5(cKO) intestinal epithelial cells (IECs), Lpar2 was upregulated and blocking LPA(2) function reduced proliferation and increased apoptosis of Lpar5(cKO) IECs. Similar to Lpar5(cKO) mice, the absence of Lpar2 (Lpar2(-/-)) resulted in upregulation of Lpar5 in IECs, indicating that LPA(2) and LPA(5) reciprocally compensate for the loss of each other. Blocking LPA(2) in Lpar5(cKO) enteroids reduced phosphorylation of Akt, indicating that LPA(2) maintains the growth of Lpar5(cKO) enteroids through activation of the PI3K-Akt pathway. The present study provides evidence that loss of an LPAR can be compensated by another LPAR.

Although miRNAs are involved in almost all processes of normal human cells, they are also involved in the abnormal functions of cancer cells. MiRNAs can play dual regulatory roles in cancer, acting either as tumor suppressors or as tumor promoters, depending on the target, tumor type, and stage. In the current review, we discuss the present status of miRNA modulation in the setting of lysophosphatidic acid (LPA) signaling. LPA is produced from lysophosphatidylcholine by the enzyme autotaxin and signals via a range of G protein-coupled receptors to affect cellular processes, which ultimately causes changes in cell morphology, survival, proliferation, differentiation, migration, and adhesion. Several studies have identified miRNAs that are over-expressed in response to stimulation by LPA, but their functional roles have not yet been fully clarified.

Therefore, deciphering the factors that impact motor neuron (MN) excitability offers an opportunity to uncover further aetiopathogenic mechanisms, neuroprotective agents, therapeutic targets, and/or biomarkers in ALS. Here, we hypothesised that the lipokine lysophosphatidic acid (lpa) regulates MN excitability via the G-protein-coupled receptor lpa(1). Then, modulating lpa(1)-mediated signalling might affect disease progression in the ALS SOD1-G93A mouse model.Methods The influence of lpa-lpa(1) signalling on the electrical properties, Ca2+ dynamic and survival of MNs was tested in vitro. Expression of lpa(1) in cultured MNs and in the spinal cord of SOD1-G93A mice was analysed. ALS mice were chronically treated with a small-interfering RNA against lpa(1) (siRNA(lpa1)) or with the lpa(1) inhibitor AM095. Motor skills, MN loss, and lifespan were evaluated.Results AM095 reduced MN excitability. Conversely, exogenous lpa increased MN excitability by modulating task1 'leak' potassium channels downstream of lpa(1). Lpa-lpa(1) signalling evoked an excitotoxic response in MNs via voltage-sensitive calcium channels. Cultured SOD1-G93A MNs displayed lpa(1) upregulation and heightened vulnerability to lpa. In transgenic mice, lpa(1) was upregulated mostly in spinal cord MNs before cell loss. Chronic administration of either siRNA(lpa1) or AM095 reduced lpa(1) expression at least in MNs, delayed MN death, improved motor skills, and prolonged life expectancy of ALS mice.Conclusions These results suggest that stressed lpa-lpa(1) signalling contributes to MN degeneration in SOD1-G93A mice.

The release of large PS+ REVs required higher concentrations of LPA. RBCs were not activated by LPA 20:4. Interestingly, blockade of LPA2 enhanced LPA-mediated PS REV release in RBCs. Furthermore, LPA receptor agonists and antagonists highlighted that LPA 20:4 inhibited LPA3dependent PS exposure and, through the LPA2 receptor, inhibited PS REV production. Activation of RBCs with LPA 18:1 in normal plasma stimulated the release of PS and PS+ REVs.

LPA levels (sum of 16:0, 18:0, 18:1, 18:2, and 20:4 LPA) were higher in the renal cortex of hypertensive Dahl salt-sensitive (Dahl S) rats fed a high-salt diet than those in normotensive rats fed a low-salt diet (296.6 +/- 22.9 vs. 196.3 +/- 8.5 nmol/g protein).

Cell viability was determined by a luminescence assay.Key findings: Cannabinoid agonists induced activation of both ERK1/2 and p38 MAP kinases. The effects of the CB1/CB2 receptor agonist HU210 were antagonized by the CB1 antagonist rimonabant, whereas the responses to the CB2 agonist JWH133 were blocked by the CB2 antagonist SR144528. HU210 reduced the apoptotic cell death induced by the pro-inflammatory cytokine TNF-alpha, whereas JWH133 enhanced the cytokine cytotoxicity. Blockade of ERK1/2 and p38 MAPK activation abrogated the HU210 pro-survival and the JWH133 pro-apoptotic effects, respectively. HU210 and the endocannabinoid anandamide, but not JWH133, potentiated ERK1/2 stimulation by LPA and the tricyclic antidepressant amitriptyline acting through the LPA(1) receptor. HU210 enhanced amitriptyline-stimulated CREB phosphorylation and protection against TNF-alpha-induced apoptosis, whereas JWH133 had no effect.

Here, lipidomics has been used to explore the early impact of alginate (ALG) hydrogel architecture (2D films or 3D printed scaffolds) and the type of gelling agent (CaCl2 or FeCl3) on the lipid profile of human fibroblasts.Methods: 2D and 3D ALG scaffolds were prepared and characterized in terms of water content, swelling, mechanical resistance and morphology before human fibroblast seeding (8 days). Using a liquid chromatographytriple quadrupole-tandem mass spectrometry approach, selected ceramides (CER), lysophosphatidylcholines (LPC), lysophosphatidic acids (LPA) and free fatty acids (FFA) were analyzed.Results: The results showed a clear alteration in the CER expression profile depending of both the geometry and the gelling agent used to prepare the hydrogels. As for LPCs, the main parameter affecting their distribution is the scaffold architecture with a significant decrease in the relative expression levels of the species with higher chain length (C20 to C22) for 3D scaffolds compared to 2D films. In the case of FFAs and LPAs only slight differences were observed as a function of scaffold geometry or gelling agent.Conclusions: Variations in the cell membrane lipid profile were observed for 3D cell cultures compared to 2D and these data are consistent with activation processes occurring through the mutual interactions between fibroblasts and ALG support. These unknown physiologically relevant changes add insights into the discussion about the relationship between biomaterial and the variations of cell biological functions.}, keywords = {fatty acids; Lysophosphatidylcholines; HUMAN FIBROBLASTS; Liquid chromatography-Mass spectrometry; Ceramides; Alginate; 3D printing; Lysophosphatidic acids}, year = {2021}, eissn = {1872-8006}, orcid-numbers = {Remaggi, Giulia/0000-0001-7488-1136} } @article{MTMT:31688911, title = {Potential association of plasma lysophosphatidic acid (LPA) species with cognitive impairment in abstinent alcohol use disorders outpatients}, url = {https://m2.mtmt.hu/api/publication/31688911}, author = {Garcia-Marchena, Nuria and Pizarro, Nieves and Pavon, Francisco J. and Martinez-Huelamo, Miriam and Flores-Lopez, Maria and Requena-Ocana, Nerea and Araos, Pedro and Silva-Pena, Daniel and Suarez, Juan and Santin, Luis J. and de la Torre, Rafael and Rodriguez de Fonseca, Fernando and Serrano, Antonia}, doi = {10.1038/s41598-020-74155-0}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {10}, unique-id = {31688911}, abstract = {Lysophosphatidic acid (LPA) species are bioactive lipids participating in neurodevelopmental processes.

Data derived from transcriptome and secretome analyses of primary ascite-derived cells indicate that (a) the major route of LPA synthesis is the consecutive action of a secretory phospholipase A(2) (PLA(2)) and autotaxin, (b) that the components of this pathway are coordinately upregulated in ascites, and (c) that CD163+CD206+ tumor-associated macrophages play an essential role as main producers of PLA(2)G7 and autotaxin. The latter conclusion is consistent with mass spectrometry-based metabolomic analyses of conditioned medium from ascites cells, which showed that tumor-associated macrophages, but not tumor cells, are able to produce 20:4 acyl-LPA in lipid-free medium. Furthermore, our transcriptomic data revealed that LPA receptor (LPAR) genes are expressed in a clearly cell type-selective manner: While tumor cells express predominantly LPAR1-3, macrophages and T cells also express LPAR5 and LPAR6 at high levels, pointing to cell type-selective LPA signaling pathways.

Recently, hydrophilic interaction liquid chromatography (HILIC) has demonstrated the ability to perform lipidomic analyses of biological samples. In the present study, we developed the quantitative measurement of cPA and its related lipid species, such as lysophosphatidic acid (LPA) and lysophosphatidylcholine (LPC), in rat serum using HILIC equipped with tandem-mass spectrometry (MS/MS). The lipid analysis using HILIC-MS/MS system demonstrated high linearity and reproducibility. The modified Bligh and Dyer method using citric acid was showed high efficiency on the extraction of cPA and LPA without contamination of artificial products. In rat serum, cPA and LPC contained more saturated fatty acids such as palmitic acid and stearic acid than unsaturated fatty acids, whereas LPA and phosphatidylcholine more contained unsaturated fatty acids than saturated fatty acids.

LPAR2 mRNA was overexpressed in HGSC cells in effusions compared to solid lesions, with opposite findings for LPAR3 and LPAR6 mRNA and ATX protein. Higher LPAR1 levels were significantly related to longer overall survival (OS) in pre-chemotherapy effusions (p = 0.027). Conversely, higher expression of LPAR1, LPAR2, and LPAR5 in post-chemotherapy effusions was significantly associated with shorter OS (p = 0.037, p = 0.025 and p = 0.021, respectively) and progression-free survival (PFS) (p < 0.001, p = 0.007 and p < 0.001, respectively) in univariate survival analysis.

It is estimated that secretory diarrhea causes 2.5 million deaths annually among children under the age of five in the developing world. A critical barrier in treating diarrheal disease is lack of easy-to-use effective treatments. While antibiotics may shorten the length and severity of diarrhea, oral rehydration remains the primary approach in managing secretory diarrhea. Existing treatments mostly depend on reconstituting medicines with water that is often contaminated which can be an unresolved problem in the developing world. Standard treatments for secretory diarrhea also include drugs that decrease intestinal motility. This approach is less than ideal because in cases where infection is the cause, this can increase the incidence of bacterial translocation and the potential for sepsis. Our goal is to develop a safe, effective, easy-to-use, and inexpensive treatment to reduce fluid loss in secretory diarrhea. We have developed Rx100, which is a metabolically stable analog of lysophosphatidic acid. We tested the hypothesis that Rx100, similarly to lysophosphatidic acid, inhibits the activation of the cystic fibrosis transmembrane regulator CI channel and also reduces barrier permeability resulting in the decrease of fluid loss in multiple etiologies of secretory diarrhea. Here we have established the bioavailability and efficacy of Rx100 in cholera toxin-induced secretory diarrhea models.

In the present study, mRNA expression of all 6 LPA receptor genes was detected in murine aortic VSMCs, with the highest levels of LPA1, LPA2, LPA4, and LPA6 In endothelium-denuded thoracic aorta (TA) and abdominal aorta (AA) segments, 1-oleoyl-LPA and the LPA1-3 agonist VPC31143 induced dose-dependent vasoconstriction. VPC31143-induced AA contraction was sensitive to pertussis toxin (PTX), the LPA1&3 antagonist Ki16425, and genetic deletion of LPA1 but not that of LPA2 or inhibition of LPA3 by diacylglycerol pyrophosphate. Surprisingly, vasoconstriction was also diminished in vessels lacking cyclooxygenase-1 [COX1 knockout (KO)] or the thromboxane prostanoid (TP) receptor (TP KO). VPC31143 increased thromboxane A2 (TXA2) release from TA of wild-type, TP KO, and LPA2 KO mice but not from LPA1 KO or COX1 KO mice, and PTX blocked this effect. Our findings indicate that LPA causes vasoconstriction in VSMCs, mediated by LPA1-, Gi-, and COX1-dependent autocrine/paracrine TXA2 release and consequent TP activation. We propose that this new-found interaction between the LPA/LPA1 and TXA2/TP pathways plays significant roles in vasoregulation, hemostasis, thrombosis, and vascular remodeling.-Dancs, P.

They play critical roles in numerous cellular and physiological processes, including cell proliferation, differentiation, neurotransmission, development and apoptosis. Consequently, aberrant receptor activity has been demonstrated in numerous disorders/diseases, and as a result GPCRs have become the most successful drug target class in pharmaceuticals treating a wide variety of indications such as pain, inflammation, neurobiological and metabolic disorders. Many independent studies have also demonstrated a key role for GPCRs in tumourigenesis, establishing their involvement in cancer initiation, progression, and metastasis. Given the growing appreciation of the role(s) that GPCRs play in cancer pathogenesis, it is surprising to note that very few GPCRs have been effectively exploited in pursuit of anti-cancer therapies. The present review provides a broad overview of the roles that various GPCRs play in cancer growth and development, highlighting the potential of pharmacologically modulating these receptors for the development of novel anti-cancer therapeutics. © 2017 Elsevier Inc.}, keywords = {Animals; Inflammation; Humans; APOPTOSIS; metabolism; MICE; CANCER; GENETICS; DISEASE PROGRESSION; AGONISTS; PAIN;

Lysophosphatidic acid (LPA) is a major lysophospholipid found systemically, and its levels are elevated in certain pathological settings, such as cancer and infections. In this study, we demonstrate that BCR signal transduction by mature murine B cells is inhibited upon LPA engagement of the LPA5 (GPR92) receptor via a Galpha12/13-Arhgef1 pathway. The inhibition of BCR signaling by LPA5 manifests by impaired intracellular calcium store release and most likely by interfering with inositol 1,4,5-triphosphate receptor activity. We further show that LPA5 also limits Ag-specific induction of CD69 and CD86 expression and that LPA5-deficient B cells display enhanced Ab responses. Thus, these data show that LPA5 negatively regulates BCR signaling, B cell activation, and immune response. Our findings extend the influence of lysophospholipids on immune function and suggest that alterations in LPA levels likely influence adaptive humoral immunity.}, keywords = {Animals; MICE; Mice, Knockout; B-Lymphocytes/*immunology; Signal Transduction/genetics/*immunology; Antibody Formation/*physiology; Receptors, Lysophosphatidic Acid/genetics/*immunology; Receptors, Antigen, B-Cell/genetics/*immunology; Lectins, C-Type/genetics/immunology; Immunity, Humoral/*physiology; Gene Expression Regulation/genetics/immunology; GTP-Binding Protein alpha Subunits, G12-G13/genetics/immunology; Antigens, Differentiation, T-Lymphocyte/genetics/immunology; Antigens, CD86/genetics/immunology; Antigens, CD/genetics/immunology}, year = {2014}, eissn = {1550-6606}, pages = {85-95}, orcid-numbers = {Tigyi, Gabor/0000-0001-5371-171X} } @article{MTMT:26413664, title = {Convergence of vitamin D and lysophosphatidic acid signaling in stimulating human osteoblast maturation}, url = {https://m2.mtmt.hu/api/publication/26413664}, author = {Mansell, J.P.}, doi = {10.3389/fphys.2014.00263}, journal-iso = {FRONT PHYSIOL}, journal = {FRONTIERS IN PHYSIOLOGY}, volume = {5}, unique-id = {26413664}, year = {2014}, eissn = {1664-042X} } @article{MTMT:26417950, title = {Docosatetraenoyl LPA is elevated in exhaled breath condensate in idiopathic pulmonary fibrosis}, url = {https://m2.mtmt.hu/api/publication/26417950}, author = {Montesi, Sydney B and Mathai, Susan K and Brenner, Laura N and Gorshkova, Irina A and Berdyshev, Evgeny V and Tager, Andrew M and Shea, Barry S}, doi = {10.1186/1471-2466-14-5}, journal-iso = {BMC PULM MED}, journal = {BMC PULMONARY MEDICINE}, volume = {14}, unique-id = {26417950}, issn = {1471-2466}, year = {2014}, eissn = {1471-2466} } @article{MTMT:26413661, title = {Melanoma Cells Break Down LPA to Establish Local Gradients That Drive Chemotactic Dispersal}, url = {https://m2.mtmt.hu/api/publication/26413661}, author = {Muinonen-Martin, Andrew J and Susanto, Olivia and Zhang, Qifeng and Smethurst, Elizabeth and Faller, William J and Veltman, Douwe M and Kalna, Gabriela and Lindsay, Colin and Bennett, Dorothy C and Sansom, Owen J and Herd, Robert and Jones, Robert and Machesky, Laura M and Wakelam, Michael J O and Knecht, David A and Insall, Robert H}, doi = {10.1371/journal.pbio.1001966}, journal-iso = {PLOS BIOL}, journal = {PLOS BIOLOGY}, volume = {12}, unique-id = {26413661}, issn = {1544-9173}, year = {2014}, eissn = {1545-7885}, orcid-numbers = {Susanto, Olivia/0000-0001-6360-1952; Sansom, Owen J/0000-0001-9540-3010} } @article{MTMT:26416548, title = {Complexities of lysophospholipid signalling in glioblastoma}, url = {https://m2.mtmt.hu/api/publication/26416548}, author = {Ng, Wayne and Pebay, Alice and Drummond, Katharine and Burgess, Antony and Kaye, Andrew H and Morokoff, Andrew}, doi = {10.1016/j.jocn.2014.02.013}, journal-iso = {J CLIN NEUROSCI}, journal = {JOURNAL OF CLINICAL NEUROSCIENCE}, volume = {21}, unique-id = {26416548}, issn = {0967-5868}, year = {2014}, eissn = {1532-2653}, pages = {893-898}, orcid-numbers = {Pebay, Alice/0000-0002-7408-9453; Morokoff, Andrew/0000-0002-5159-3438} } @article{MTMT:26417473, title = {Challenges in accurate quantitation of lysophosphatidic acids in human biofluids}, url = {https://m2.mtmt.hu/api/publication/26417473}, author = {Onorato, Joelle M and Shipkova, Petia and Minnich, Anne and Aubry, Anne-Francoise and Easter, John and Tymiak, Adrienne}, doi = {10.1194/jlr.D050070}, journal-iso = {J LIPID RES}, journal = {JOURNAL OF LIPID RESEARCH}, volume = {55}, unique-id = {26417473}, issn = {0022-2275}, year = {2014}, eissn = {1539-7262}, pages = {1784-1796} } @article{MTMT:2756690, title = {Design and synthesis of sulfamoyl benzoic acid analogues with subnanomolar agonist activity specific to the LPA2 receptor.}, url = {https://m2.mtmt.hu/api/publication/2756690}, author = {Patil, R and Fells, JI and Szabó, Erzsébet and Lim, KG and Norman, DD and Balogh, Andrea and Patil, S and Strobos, J and Miller, DD and Tigyi, Gabor}, doi = {10.1021/jm5007116}, journal-iso = {J MED CHEM}, journal = {JOURNAL OF MEDICINAL CHEMISTRY}, volume = {57}, unique-id = {2756690}, issn = {0022-2623}, abstract = {Lysophosphatidic acid (LPA) is a growth factor-like mediator and a ligand for multiple GPCR.

Mechanical removal of the endothelium or genetic deletion of endothelial nitric oxide synthase (eNOS) not only diminished vasorelaxation by LPA or VPC31143 but converted it to vasoconstriction. Freshly isolated mouse aortic endothelial cells expressed LPA1, LPA2, LPA4 and LPA5 transcripts. The LPA1,3 antagonist Ki16425, the LPA1 antagonist AM095, and the genetic deletion of LPA1, but not that of LPA2, abolished LPA-induced vasorelaxation. Inhibition of the phosphoinositide 3 kinase-protein kinase B/Akt pathway by wortmannin or MK-2206 failed to influence the effect of LPA. However, pharmacological inhibition of phospholipase C (PLC) by U73122 or edelfosine, but not genetic deletion of PLCepsilon, abolished LPA-induced vasorelaxation and indicated that a PLC enzyme, other than PLCepsilon, mediates the response.

This is explained mainly since autotaxin produces the lipid growth factor, lysophosphatidate (LPA), which stimulates cell division, survival and migration. It has recently become evident that these signaling effects of LPA also produce resistance to chemotherapy and radiation-induced cell death. This results especially from the stimulation of LPA(2) receptors, which depletes the cell of Siva-1, a pro-apoptotic signaling protein and stimulates prosurvival kinase pathways through a mechanism mediated via TRIP-6. LPA signaling also increases the formation of sphingosine 1-phosphate, a pro-survival lipid. At the same time, LPA decreases the accumulation of ceramides, which are used in radiation therapy and by many chemotherapeutic agents to stimulate apoptosis. The signaling actions of extracellular LPA are terminated by its dephosphorylation by a family of lipid phosphate phosphatases (LPP) that act as ecto-enzymes. In addition, lipid phosphate phoshatase-1 attenuates signaling downstream of the activation of both LPA receptors and receptor tyrosine kinases. This makes many cancer cells hypersensitive to the action of various growth factors since they often express low LPP1/3 activity. Increasing our understanding of the complicated signaling pathways that are used by LPA to stimulate cell survival should identify new therapeutic targets that can be exploited to increase the efficacy of chemo- and radio-therapy.
