Morphological changes involving actin polymerization are mediated by at least two cognate G protein-coupled receptors, LPA<jats:sub>1<\/jats:sub>\/EDG-2 or LPA<jats:sub>2<\/jats:sub>\/EDG-4. Herein, we show that LPA can also induce actin depolymerization preceding actin polymerization within single TR mouse immortalized neuroblasts. Actin depolymerization resulted in immediate loss of membrane ruffling, whereas actin polymerization resulted in process retraction. Each pathway was found to be independent: depolymerization mediated by intracellular calcium mobilization, and \u03b1-actinin activity and polymerization mediated by the activation of the small Rho GTPase. \u03b1-Actinin\u2013mediated depolymerization seems to be involved in growth cone collapse of primary neurons, indicating a physiological significance of LPA-induced actin depolymerization. Further evidence for dual regulation of actin rearrangement was found by heterologous retroviral transduction of either lpa<jats:sub>1<\/jats:sub>orlpa<jats:sub>2<\/jats:sub>in B103 cells that neither express LPA receptors nor respond to LPA, to confer both forms of LPA-induced actin rearrangements. These results suggest that diverging intracellular signals from a single type of LPA receptor could regulate actin depolymerization, as well as polymerization, within a single cell. This dual actin rearrangement may play a novel, important role in regulation of the neuronal morphology and motility during brain development.<\/jats:p>","DOI":"10.1091\/mbc.01-09-0465","type":"journal-article","created":{"date-parts":[[2002,9,30]],"date-time":"2002-09-30T17:42:46Z","timestamp":1033407766000},"page":"2692-2705","source":"Crossref","is-referenced-by-count":53,"title":["Dual Regulation of Actin Rearrangement through Lysophosphatidic Acid Receptor in Neuroblast Cell Lines: Actin Depolymerization by Ca<sup>2+<\/sup>-\u03b1-Actinin and Polymerization by Rho"],"prefix":"10.1091","volume":"13","author":[{"given":"Nobuyuki","family":"Fukushima","sequence":"first","affiliation":[{"name":"Department of Molecular Biochemistry, Hokkaido University Graduate School of Medicine, Sapporo 060-8638, Japan;"},{"name":"Department of Pharmacology,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Isao","family":"Ishii","sequence":"additional","affiliation":[{"name":"Department of Pharmacology,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshiaki","family":"Habara","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, Hokkaido University Graduate School of Veterinary Medicine, Sapporo 060-0818, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cara B.","family":"Allen","sequence":"additional","affiliation":[{"name":"Neurosciences Program,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jerold","family":"Chun","sequence":"additional","affiliation":[{"name":"Department of Pharmacology,"},{"name":"Neurosciences Program,"},{"name":"Biomedical Sciences Program, School of Medicine, University of California, San Diego, La Jolla, California 92093-0636;"},{"name":"Molecular Neuroscience, Merck Research Laboratories, San Diego, California 91212; and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1076","reference":[{"key":"B1","doi-asserted-by":"crossref","first-page":"5592","DOI":"10.1016\/S0021-9258(18)45614-1","volume":"262","author":"Akiyama T.","year":"1987","journal-title":"J.
