Blockade of AQP1 in the CP reduce the production of cerebrospinal fluid (CSF). Downregulation of AQP1 might be protective against some neurological disorders correlated with increased intracranial pressure and\/or poor drainage of CSF. Curcumin, the major constituent of the rhizome of\n                    <jats:italic toggle=\"yes\">Curcuma longa<\/jats:italic>\n                    , has been shown to inhibit potassium channels, Na\n                    <jats:sup>+<\/jats:sup>\n                    \u2013K\n                    <jats:sup>+<\/jats:sup>\n                    ATPase, as well as AQP3 in some cells. We therefore speculated that curcumin might be a useful tool to inhibit and\/or decrease AQP1, and thus might be useful in the regulation of CSF production in pathophysiological conditions, including traumatic brain injury, hydrocephalus, stroke, systemic hyponatremia, acute cerebral edema, and hypertension. Choroidal epithelial cells of the lateral ventricle of Wistar rats were isolated and grown in\n                    <jats:italic toggle=\"yes\">in-vitro<\/jats:italic>\n                    cultures for 24\u2009h. Curcumin was then added to the medium at different concentrations, and the cell viability tested by the (3,4,5-dimethylthiazol-2-yl)-2-5-diphenyltetrazolium bromide assay. Additional wells of cells were tested for AQP1 protein expression using immunocytochemistry, immunoblotting, and flow cytometry. Our results showed that curcumin treatment decreases AQP1 expression in rat choroid epithelium cells in a dose-dependent manner. We conclude that curcumin may be a useful tool to regulate CSF production in pathophysiological conditions such as hydrocephalus, systemic hyponatremia, hypertension, and other neurological conditions.\n                  <\/jats:p>","DOI":"10.1089\/jmf.2012.0208","type":"journal-article","created":{"date-parts":[[2013,6,4]],"date-time":"2013-06-04T09:56:28Z","timestamp":1370339788000},"page":"504-510","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":20,"title":["Curcumin Downregulates Aquaporin-1 Expression in Cultured Rat Choroid Plexus Cells"],"prefix":"10.1177","volume":"16","author":[{"given":"Mohammad","family":"Nabiuni","sequence":"first","affiliation":[{"name":"Kharazmi University (TMU)","place":["Iran"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zahra","family":"Nazari","sequence":"additional","affiliation":[{"name":"Kharazmi University (TMU)","place":["Iran"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zahra","family":"Safaeinejad","sequence":"additional","affiliation":[{"name":"Kharazmi University (TMU)","place":["Iran"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bahram","family":"Delfan","sequence":"additional","affiliation":[{"name":"Lorestan University of Medical Sciences","place":["Iran"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaleel A.","family":"Miyan","sequence":"additional","affiliation":[{"name":"The University of Manchester","place":["United Kingdom"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2013,6,1]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.ph.58.030196.003155"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.90.15.7275"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1152\/ajpcell.00433.2005"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/glia.20916"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1085\/jgp.20028597"},{"key":"e_1_3_3_7_2","first-page":"525","article-title":"Aquaporin-1 deletion reduces osmotic water permeability and cerebrospinal fluid production","volume":"86","author":"Oshio K","year":"2003","unstructured":"Oshio K, , Song Y, , Verkman AS, , Manley GT.
