Recent studies have identified the presence of important quantities of labile zinc in the conducting airways. We hypothesized that modulation of this labile zinc could influence the production of proinflammatory chemokines in respiratory epithelial cells. The zinc chelator N,N,N\u2032 ,N\u2032-tetrakis(2-pyridylmethyl)ethylenediamine (TPEN) and the heavy metal chelator 2,3-dimercapto-1-propanesulfonic acid (DMPS) were used to reduce the labile zinc content of A549, BEAS-2B, and HFL-1 cells. Northern blot analysis and RNase protection assay were used to study the effects of the zinc chelators on mRNA expression. DMPS and TPEN specifically inhibited the production of eotaxin, regulated on activation, normal T-cell expressed, and presumably secreted, and monocyte chemotactic protein-1 in TNF-\u03b1-stimulated respiratory epithelial cells and fibroblasts through labile zinc chelation. The inhibitory effects of DMPS and TPEN were associated with the decreased binding of the zinc-finger transcription factor GATA-1, whereas no change in NF-\u03baB activation was observed. Together these results demonstrate that modulation of the labile pool of zinc can regulate gene expression and protein synthesis of C-C chemokines in lung epithelial cells and fibroblasts.<\/jats:p>","DOI":"10.1152\/ajplung.00406.2002","type":"journal-article","created":{"date-parts":[[2015,3,3]],"date-time":"2015-03-03T20:21:46Z","timestamp":1425414106000},"page":"L719-L729","source":"Crossref","is-referenced-by-count":40,"title":["Zinc chelators inhibit eotaxin, RANTES, and MCP-1 production in stimulated human airway epithelium and fibroblasts"],"prefix":"10.1152","volume":"285","author":[{"given":"Martin","family":"Richter","sequence":"first","affiliation":[{"name":"Unit\u00e9 de recherche pulmonaire, Facult\u00e9 de m\u00e9decine, Universit\u00e9 de Sherbrooke, Sherbrooke, Qu\u00e9bec, Canada J1H 5N4"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9 M.","family":"Cantin","sequence":"additional","affiliation":[{"name":"Unit\u00e9 de recherche pulmonaire, Facult\u00e9 de m\u00e9decine, Universit\u00e9 de Sherbrooke, Sherbrooke, Qu\u00e9bec, Canada J1H 5N4"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia","family":"Beaulieu","sequence":"additional","affiliation":[{"name":"Unit\u00e9 de recherche pulmonaire, Facult\u00e9 de m\u00e9decine, Universit\u00e9 de Sherbrooke, Sherbrooke, Qu\u00e9bec, Canada J1H 5N4"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandre","family":"Cloutier","sequence":"additional","affiliation":[{"name":"Unit\u00e9 de recherche pulmonaire, Facult\u00e9 de m\u00e9decine, Universit\u00e9 de Sherbrooke, Sherbrooke, Qu\u00e9bec, Canada J1H 5N4"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Lariv\u00e9e","sequence":"additional","affiliation":[{"name":"Unit\u00e9 de recherche pulmonaire, Facult\u00e9 de m\u00e9decine, Universit\u00e9 de Sherbrooke, Sherbrooke, Qu\u00e9bec, Canada J1H 5N4"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"24","reference":[{"key":"REF1","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.154.6.8970374"},{"key":"REF2","doi-asserted-by":"publisher","DOI":"10.1006\/bbrc.1996.1463"},{"key":"REF3","doi-asserted-by":"publisher","DOI":"10.1046\/j.1440-1711.1999.00825.x"},{"key":"REF4","doi-asserted-by":"crossref","unstructured":"Danoff TM, Lalley PA, Chang YS, Heeger PS, and Neilson EG.Cloning, genomic organization, and chromosomal localization of the Scya5 gene encoding the murine chemokine RANTES.J Immunol152: 1182-1189, 1994.","DOI":"10.4049\/jimmunol.152.3.1182"},{"key":"REF5","doi-asserted-by":"publisher","DOI":"10.1152\/ajplung.1997.272.1.L148"},{"key":"REF6","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.95.7.3333"},{"key":"REF7","doi-asserted-by":"publisher","DOI":"10.1016\/S0091-6749(00)90187-8"},{"key":"REF8","unstructured":"Goodman LS, Gilman A, Hardman JG, Gilman AG, and Limbird LE.Goodman & Gilman's the Pharmacological Basis of Therapeutics.
