Lysophosphatidic acid (LPA) is a pleiotropic bioactive lysophospholipid involved in inflammatory mediator synthesis. Signaling through p38MAPK, ERK, Rho kinase, and MSK-CREB contributes to LPA-mediated IL-8 production in fibroblast-like synoviocytes (FLS) from rheumatoid arthritis (RA) patients. The study was undertaken to investigate how LPA activates MSKs and how signaling crosstalk between T...
BACKGROUND Lysophosphatidic acid (LPA) governs a number of physiologic and pathophysiological processes. Malignant ascites fluid is rich in LPA, and LPA receptors are aberrantly expressed by ovarian cancer cells, implicating LPA in the initiation and progression of ovarian cancer. However, there is an absence of systematic data critically analyzing the transcriptional changes induced by LPA in ...
Lysophosphatidic acid (LPA) is a bioactive phospholipid that signals through a family of at least six G protein-coupled receptors designated LPA₁₋₆. LPA type 1 receptor (LPA₁) exhibits widespread tissue distribution and regulates a variety of physiological and pathological cellular functions. Here, we evaluated the in vitro pharmacology, pharmacokinetic, and pharmacodynamic properties of the LP...
Lysophosphatidic acid (LPA) is present at high concentrations in ascites and plasma of ovarian cancer patients. Studies conducted in experimental models demonstrate that LPA promotes ovarian cancer invasion/ metastasis by up-regulating protease expression, elevating protease activity, and enhancing angiogenic factor expression. In this study, we investigated the effect of LPA on ovarian cancer ...
Lysophosphatidic acid (LPA) is an agonist for peroxisome proliferator activated receptor-γ (PPARγ). Although glycerol-3-phosphate acyltransferase-1 (GPAT1) esterifies glycerol-3-phosphate to form LPA, an intermediate in the de novo synthesis of glycerolipids, it has been assumed that LPA synthesized by this route does not have a signaling role. The availability of Chinese Hamster Ovary (CHO) ce...
Lysophosphatidic acid (LPA) is produced by tumor cells and is present in the ascites fluid of ovarian cancer patients. To determine the role of endogenous LPA in the ovarian cancer cell line SKOV3, we treated cells with the LPA receptor antagonist VPC32183 and found that it inhibited cell growth and induced apoptosis. Exogenous LPA further stimulated ERK and Akt phosphorylation and NF-κB activi...
Lysophosphatidic acid (LPA) is a bioactive phospholipid that activates cell proliferation, differentiation and migration via the activation of its membrane-bound receptors (LPAR 1 to 6) expressed in various tissues and organs. Adipose tissue produces LPA, which, in turn, increases preadipocyte proliferation, mainly through the stimulation of LPA1R. However, while LPA plasma levels increase with...
Lysophosphatidic acid (LPA) is a simple bioactive phospholipid with diverse physiological actions on many cell types. LPA induces proliferative and/or morphological effects and has been proposed to be involved in biologically important processes including neurogenesis, myelination, angiogenesis, wound healing, and cancer progression. LPA acts through specific G protein-coupled, seven-transmembr...
This chapter gives an applied introduction to latent profile and class analysis (LPA/LCA). LPA/LCA are model-based methods for clustering individuals in unobserved groups. Their primary goals probing whether and, if so, how many classes can be identified the data estimating their proportional size response profiles. Moreover, membership serve as a predictor or outcome external variables. Substa...
Lysophosphatidic acid (LPA) acts via binding to specific G protein-coupled receptors and has been implicated in the biology of breast cancer. Here, we characterize LPA receptor expression patterns in common established breast cancer cell lines and their contribution to breast cancer cell motility. By measuring expression of the LPA receptors LPA1, LPA2, and LPA3 with real-time quantitative PCR,...
