At the site of first contact, the gingiva is exposed to aromatic amines and polycyclic hydrocarbons. These are metabolized by the N-acetyltransferases (NAT), leading to local detoxification and\/or activation reactions contributing to the risk of periodontal destruction in smokers. The purpose of this study was to detect the expression of N-acetyltransferase isoenzymes NAT1 and NAT2 in periodontal granulation tissue. In 24 specimens obtained from periodontitis patients or control subjects, mRNA encoding for NAT1 and NAT2 was detected by RT-PCR, and proteins were identified by immunohistochemistry. In periodontal granulation tissues, immunoreactivity for NAT1 and NAT2 was detected in infiltrating leukocytes and fibroblasts. In normal gingiva, both enzymes were found in epithelial cells, whereas NAT1 was also detected in endothelial cells. The results suggest that these enzymes may play a role in the defense against xenobiotics and the accelerated progression of periodontal disease in smokers.<\/jats:p>","DOI":"10.1177\/154405910208100512","type":"journal-article","created":{"date-parts":[[2009,1,8]],"date-time":"2009-01-08T19:39:42Z","timestamp":1231443582000},"page":"349-353","source":"Crossref","is-referenced-by-count":11,"title":["Expression of N-acetyltransferases in Periodontal Granulation Tissue"],"prefix":"10.1177","volume":"81","author":[{"given":"P.","family":"Meisel","sequence":"first","affiliation":[{"name":"Department of Pharmacology,"},{"name":"Department of Anatomy, and"},{"name":"Department of Human Genetics, Ernst Moritz Arndt University Greifswald, F.-Loeffler-Str. 23d, D-17487 Greifswald; and"},{"name":"Dental Clinics, Department of Periodontology, Rotgerberstr. 8, D-17487 Greifswald, Germany;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Giebel","sequence":"additional","affiliation":[{"name":"Department of Pharmacology,"},{"name":"Department of Anatomy, and"},{"name":"Department of Human Genetics, Ernst Moritz Arndt University Greifswald, F.-Loeffler-Str. 23d, D-17487 Greifswald; and"},{"name":"Dental Clinics, Department of Periodontology, Rotgerberstr. 8, D-17487 Greifswald, Germany;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Peters","sequence":"additional","affiliation":[{"name":"Department of Pharmacology,"},{"name":"Department of Anatomy, and"},{"name":"Department of Human Genetics, Ernst Moritz Arndt University Greifswald, F.-Loeffler-Str. 23d, D-17487 Greifswald; and"},{"name":"Dental Clinics, Department of Periodontology, Rotgerberstr. 8, D-17487 Greifswald, Germany;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Foerster","sequence":"additional","affiliation":[{"name":"Department of Pharmacology,"},{"name":"Department of Anatomy, and"},{"name":"Department of Human Genetics, Ernst Moritz Arndt University Greifswald, F.-Loeffler-Str. 23d, D-17487 Greifswald; and"},{"name":"Dental Clinics, Department of Periodontology, Rotgerberstr. 8, D-17487 Greifswald, Germany;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I.","family":"Cascorbi","sequence":"additional","affiliation":[{"name":"Department of Pharmacology,"},{"name":"Department of Anatomy, and"},{"name":"Department of Human Genetics, Ernst Moritz Arndt University Greifswald, F.-Loeffler-Str. 23d, D-17487 Greifswald; and"},{"name":"Dental Clinics, Department of Periodontology, Rotgerberstr. 8, D-17487 Greifswald, Germany;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Wulff","sequence":"additional","affiliation":[{"name":"Department of Pharmacology,"},{"name":"Department of Anatomy, and"},{"name":"Department of Human Genetics, Ernst Moritz Arndt University Greifswald, F.-Loeffler-Str. 23d, D-17487 Greifswald; and"},{"name":"Dental Clinics, Department of Periodontology, Rotgerberstr. 8, D-17487 Greifswald, Germany;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Fanghaenel","sequence":"additional","affiliation":[{"name":"Department of Pharmacology,"},{"name":"Department of Anatomy, and"},{"name":"Department of Human Genetics, Ernst Moritz Arndt University Greifswald, F.-Loeffler-Str. 23d, D-17487 Greifswald; and"},{"name":"Dental Clinics, Department of Periodontology, Rotgerberstr. 8, D-17487 Greifswald, Germany;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Th.","family":"Kocher","sequence":"additional","affiliation":[{"name":"Department of Pharmacology,"},{"name":"Department of Anatomy, and"},{"name":"Department of Human Genetics, Ernst Moritz Arndt University Greifswald, F.-Loeffler-Str. 23d, D-17487 Greifswald; and"},{"name":"Dental Clinics, Department of Periodontology, Rotgerberstr. 8, D-17487 Greifswald, Germany;"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2002,5,1]]},"reference":[{"key":"BADAWI-ETAL-1996","unstructured":"Badawi AF, Stern SJ, Lang NP, Kadlubar FF -1996- Cytochrome P-450 and acetyltransferase expression as biomarkers of carcinogen-DNA adduct levels and human cancer susceptibility.
