Characterization of lpa(2) (Edg4) and lpa(1)/lpa(2) (Edg2/Edg4) lysophosphatidic acid receptor knockout mice: signaling deficits without obvious phenotypic abnormality attributable to lpa(2).
Lysophosphatidic acid (LPA), a bioactive lipid produced by several cell types including postmitotic neurons and activated platelets, is thought to be involved in various biological processes, including brain development. Three cognate G protein-coupled receptors encoded by lpa(1)/lp(A1)/Edg-2/Gpcr26, lpa(2)/lp(A2)/Edg-4, and lpa(3)/lp(A3)/Edg-7 mediate the cellular effects of LPA. We have previ...
متن کاملConstitutive and lysophosphatidic acid (LPA)-induced LPA production: role of phospholipase D and phospholipase A2.
Ascitic fluid and plasma from ovarian cancer patients, but not from patients with nongynecological tumors, contain elevated levels of the bioactive phospholipid lysophosphatidic acid (LPA). We show that ovarian cancer cells constitutively produce increased amounts of LPA as compared with normal ovarian epithelium, the precursor of ovarian epithelial cancer, or breast cancer cells. In addition, ...
متن کاملThe LPA receptors.
Lysophosphatidic acid (LPA) is a growth factor-like lipid that produces many cellular responses. These responses, including actin cytoskeletal rearrangements, cell proliferation and inhibition of gap junction communication, have been documented in many cell types over the last 2 decades. Both non-receptor and receptor-mediated mechanisms had been implicated to explain these responses. A clear a...
متن کاملCycle Chains and the LPA Model
The LPA model is a three dimensional system of nonlinear difference equations that has found many applications in population dynamics and ecology. In this paper, we consider a special case of the model (a case that approximates that used in experimental bifurcation and chaos studies) and prove several theorems concerning the existence and stability of periodic cycles, invariant loops, and chaos...
متن کاملLysophosphatidic acid (LPA) signaling in vertebrate reproduction.
Lysophosphatidic acid (LPA) is a cell membrane phospholipid metabolite that can act as an extracellular signal. Its effects are mediated through at least five G protein-coupled receptors, LPA(1-5), and probably others as well. Studies in multiple species including LPAR-deficient mice and humans have identified or implicated important roles for receptor-mediated LPA signaling in multiple aspects...
