Purified quiescent human blood T lymphocytes were subjected to: (i) acute exposure to hydrogen peroxide; (ii) chronic exposure to hydrogen peroxide; and (iii) acute exposure to ionizing radiation. The cells were then stimulated for 6\u2003h. DNA-binding activities (determined by the electrophoretic mobility shift assay) of three transcription factors: NF\u03baB, AP-1 and NFAT, were abolished in the lymphocytes by all three modes of oxidative stress. The lymphocytes exhibited lipid peroxidation only upon exposure to the lowest level of hydrogen peroxide used (20\u2003\u03bcm). All three modes of oxidative stress induced catalase activity in the lymphocytes. The only exception was hydrogen peroxide at 20\u2003\u03bcm, which did not induce catalase activity. We conclude that: (i) suppression of specific transcription factor functions can potentially serve as a marker of exposure to oxidative stress and its effects on human lymphocytes; (ii) lipid peroxidation is only detectable in human lymphocytes upon exposure to weak oxidative stress which does not induce catalase activity; (iii) therefore, transcription factor DNA-binding activities are more sensitive to oxidative stress than lipid peroxidation.<\/jats:p>","DOI":"10.1046\/j.1365-2249.1998.00548.x","type":"journal-article","created":{"date-parts":[[2003,3,11]],"date-time":"2003-03-11T10:10:14Z","timestamp":1047377414000},"page":"242-247","source":"Crossref","is-referenced-by-count":36,"title":["Oxidative stress suppresses transcription factor activities in stimulated lymphocytes"],"prefix":"10.1093","volume":"112","author":[{"given":"E","family":"Flescher","sequence":"first","affiliation":[{"name":"Department of Environmental Medicine, New York University Medical Center, Tuxedo, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H","family":"Tripoli","sequence":"additional","affiliation":[{"name":"Department of Environmental Medicine, New York University Medical Center, Tuxedo, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K","family":"Salnikow","sequence":"additional","affiliation":[{"name":"Department of Environmental Medicine, New York University Medical Center, Tuxedo, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F J","family":"Burns","sequence":"additional","affiliation":[{"name":"Department of Environmental Medicine, New York University Medical Center, Tuxedo, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2001,12,25]]},"reference":[{"key":"b1_409","first-page":"246","volume":"42","author":"Imboden JB","year":"1988","journal-title":"Prog in Allerg"},{"key":"b2_410","doi-asserted-by":"crossref","first-page":"355","DOI":"10.1126\/science.2783497","volume":"243","author":"Crabtree G","year":"1989","journal-title":"Sci"},{"key":"b3_411","doi-asserted-by":"crossref","first-page":"2734","DOI":"10.4049\/jimmunol.147.8.2734","volume":"147","author":"Granelli-Piperno A","year":"1991","journal-title":"J Immunol"},{"key":"b4_412","doi-asserted-by":"crossref","first-page":"457","DOI":"10.1126\/science.2497518","volume":"244","author":"Hoyos B","year":"1989","journal-title":"Sci"},{"key":"b5_413","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.270.38.22500"},{"key":"b6_414","doi-asserted-by":"crossref","unstructured":"6 GV Buxton .
